The Free Translation Project is +a way to get maintainers of free software, translators, and users all +together, so that free software will gradually become able to speak many +languages. A few packages already provide translations for their +messages. + + If you found this `ABOUT-NLS' file inside a distribution, you may +assume that the distributed package does use GNU `gettext' internally, +itself available at your nearest GNU archive site. But you do _not_ +need to install GNU `gettext' prior to configuring, installing or using +this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work on translations can contact the appropriate team. + + When reporting bugs in the `intl/' directory or bugs which may be +related to internationalization, you should tell about the version of +`gettext' which is used. The information can be found in the +`intl/VERSION' file, in internationalized packages. + +1.1 Quick configuration advice +============================== + +If you want to exploit the full power of internationalization, you +should configure it using + + ./configure --with-included-gettext + +to force usage of internationalizing routines provided within this +package, despite the existence of internationalizing capabilities in the +operating system where this package is being installed. So far, only +the `gettext' implementation in the GNU C library version 2 provides as +many features (such as locale alias, message inheritance, automatic +charset conversion or plural form handling) as the implementation here. +It is also not possible to offer this additional functionality on top +of a `catgets' implementation. Future versions of GNU `gettext' will +very likely convey even more functionality. So it might be a good idea +to change to GNU `gettext' as soon as possible. + + So you need _not_ provide this option if you are using GNU libc 2 or +you have installed a recent copy of the GNU gettext package with the +included `libintl'. + +1.2 INSTALL Matters +=================== + +Some packages are "localizable" when properly installed; the programs +they contain can be made to speak your own native language. Most such +packages use GNU `gettext'. Other packages have their own ways to +internationalization, predating GNU `gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system already +provides the GNU `gettext' functions. If not, the included GNU +`gettext' library will be used. This library is wholly contained +within this package, usually in the `intl/' subdirectory, so prior +installation of the GNU `gettext' package is _not_ required. +Installers may use special options at configuration time for changing +the default behaviour. The commands: + + ./configure --with-included-gettext + ./configure --disable-nls + +will, respectively, bypass any pre-existing `gettext' to use the +internationalizing routines provided within this package, or else, +_totally_ disable translation of messages. + + When you already have GNU `gettext' installed on your system and run +configure without an option for your new package, `configure' will +probably detect the previously built and installed `libintl.a' file and +will decide to use this. This might not be desirable. You should use +the more recent version of the GNU `gettext' library. I.e. if the file +`intl/VERSION' shows that the library which comes with this package is +more recent, you should use + + ./configure --with-included-gettext + +to prevent auto-detection. + + The configuration process will not test for the `catgets' function +and therefore it will not be used. The reason is that even an +emulation of `gettext' on top of `catgets' could not provide all the +extensions of the GNU `gettext' library. + + Internationalized packages usually have many `po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at `configure' time by using the +`--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable `LINGUAS' +may be set, prior to configuration, to limit the installed set. +`LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +1.3 Using This Package +====================== + +As a user, if your language has been installed for this package, you +only have to set the `LANG' environment variable to the appropriate +`LL_CC' combination. If you happen to have the `LC_ALL' or some other +`LC_xxx' environment variables set, you should unset them before +setting `LANG', otherwise the setting of `LANG' will not have the +desired effect. Here `LL' is an ISO 639 two-letter language code, and +`CC' is an ISO 3166 two-letter country code. For example, let's +suppose that you speak German and live in Germany. At the shell +prompt, merely execute `setenv LANG de_DE' (in `csh'), +`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). +This can be done from your `.login' or `.profile' file, once and for +all. + + You might think that the country code specification is redundant. +But in fact, some languages have dialects in different countries. For +example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The +country code serves to distinguish the dialects. + + The locale naming convention of `LL_CC', with `LL' denoting the +language and `CC' denoting the country, is the one use on systems based +on GNU libc. On other systems, some variations of this scheme are +used, such as `LL' or `LL_CC.ENCODING'. You can get the list of +locales supported by your system for your language by running the +command `locale -a | grep '^LL''. + + Not all programs have translations for all languages. By default, an +English message is shown in place of a nonexistent translation. If you +understand other languages, you can set up a priority list of languages. +This is done through a different environment variable, called +`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' +for the purpose of message handling, but you still need to have `LANG' +set to the primary language; this is required by other parts of the +system libraries. For example, some Swedish users who would rather +read translations in German than English for when Swedish is not +available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. + + Special advice for Norwegian users: The language code for Norwegian +bokma*l changed from `no' to `nb' recently (in 2003). During the +transition period, while some message catalogs for this language are +installed under `nb' and some older ones under `no', it's recommended +for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and +older translations are used. + + In the `LANGUAGE' environment variable, but not in the `LANG' +environment variable, `LL_CC' combinations can be abbreviated as `LL' +to denote the language's main dialect. For example, `de' is equivalent +to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' +(Portuguese as spoken in Portugal) in this context. + +1.4 Translating Teams +===================== + +For the Free Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list. The up-to-date list of +teams can be found at the Free Translation Project's homepage, +`http://translationproject.org/', in the "Teams" area. + + If you'd like to volunteer to _work_ at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is _not_ the same as the list itself, it has +`-request' appended. For example, speakers of Swedish can send a +message to `sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate +_actively_ in translations, or at solving translational difficulties, +rather than merely lurking around. If your team does not exist yet and +you want to start one, or if you are unsure about what to do or how to +get started, please write to `coordinator@translationproject.org' to +reach the coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology in use. Proven linguistic skills are praised more than +programming skills, here. + +1.5 Available Packages +====================== + +Languages are not equally supported in all packages. The following +matrix shows the current state of internationalization, as of November +2007. The matrix shows, in regard of each package, for which languages +PO files have been submitted to translation coordination, with a +translation percentage of at least 50%. + + Ready PO files af am ar

Of course you have to respect the GNU Library General Public +License which covers the use of the GNU `gettext' library. This means +in particular that even non-free programs can use `libintl' as a shared +library, whereas only free software can use `libintl' as a static +library or use modified versions of `libintl'. + + Once the sources are changed appropriately and the setup can handle +the use of `gettext' the only thing missing are the translations. The +Free Translation Project is also available for packages which are not +developed inside the GNU project. Therefore the information given above +applies also for every other Free Software Project.

It is + numbered 2 because it goes with version 2 of the ordinary GPL.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Library General Public License, applies to some +specially designated Free Software Foundation software, and to any +other libraries whose authors decide to use it. You can use it for +your libraries, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if +you distribute copies of the library, or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link a program with the library, you must provide +complete object files to the recipients so that they can relink them +with the library, after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + Our method of protecting your rights has two steps: (1) copyright +the library, and (2) offer you this license which gives you legal +permission to copy, distribute and/or modify the library. + + Also, for each distributor's protection, we want to make certain +that everyone understands that there is no warranty for this free +library. If the library is modified by someone else and passed on, we +want its recipients to know that what they have is not the original +version, so that any problems introduced by others will not reflect on +the original authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that companies distributing free +software will individually obtain patent licenses, thus in effect +transforming the program into proprietary software. To prevent this, +we have made it clear that any patent must be licensed for everyone's +free use or not licensed at all. + + Most GNU software, including some libraries, is covered by the ordinary +GNU General Public License, which was designed for utility programs. This +license, the GNU Library General Public License, applies to certain +designated libraries. This license is quite different from the ordinary +one; be sure to read it in full, and don't assume that anything in it is +the same as in the ordinary license. + + The reason we have a separate public license for some libraries is that +they blur the distinction we usually make between modifying or adding to a +program and simply using it. Linking a program with a library, without +changing the library, is in some sense simply using the library, and is +analogous to running a utility program or application program. However, in +a textual and legal sense, the linked executable is a combined work, a +derivative of the original library, and the ordinary General Public License +treats it as such. + + Because of this blurred distinction, using the ordinary General +Public License for libraries did not effectively promote software +sharing, because most developers did not use the libraries. We +concluded that weaker conditions might promote sharing better. + + However, unrestricted linking of non-free programs would deprive the +users of those programs of all benefit from the free status of the +libraries themselves. This Library General Public License is intended to +permit developers of non-free programs to use free libraries, while +preserving your freedom as a user of such programs to change the free +libraries that are incorporated in them. (We have not seen how to achieve +this as regards changes in header files, but we have achieved it as regards +changes in the actual functions of the Library.) The hope is that this +will lead to faster development of free libraries. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, while the latter only +works together with the library. + + Note that it is possible for a library to be covered by the ordinary +General Public License rather than by this special one. + + GNU LIBRARY GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library which +contains a notice placed by the copyright holder or other authorized +party saying it may be distributed under the terms of this Library +General Public License (also called "this License"). Each licensee is +addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also compile or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + c) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + d) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the source code distributed need not include anything that is normally +distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Library General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16.

With this patch, the + interface is now: + GstPpluginDesc *gst_plugin__get_desc(void); + The reason we change the C structure into function, is that it is + potentially more common to have function pointers, avoiding possible + binding language limitation.

Each thread push one buffer on one pad. There are + two pads in the collectpads so the second buffer will trigger the + collect-callback. + This is what happens when the hang occurs: + The first thread pushes a buffer and initializes a cookie to the value of a + counter in the collectpads object and waits on a cond for the counter to change + and for someone to consume the buffer (i.e. _pop() it). + The second thread pushes a buffer and calls the collected callback, which + signals the cond that the test thread is waiting for. + The test thread pops both buffers (without holding any lock). Each call to + _pop() increases the counter broadcasts the condition that the first thread is + now waiting for. It then joins both threads (hangs). + The first thread wakes up and returns, since its buffer has been consumed. + The second thread starts executing again. When the callback, called by the + second thread, has returned it initializes a cookie to the value of a counter, + which has already prematurely been increased by the test thread when it popped + the buffers, and wait's on a cond for the counter to change and for someone to + consume the buffer (i.e. _pop() it).

An older version of gst-plugins-good is also + installed in that prefix, along with random other plugin modules. Now, + when doing 'make check' in the just-built gst-plugins-good tree, we + want to only load plugins from GStreamer core, gst-plugins-base, and + gst-plugins-good, but not random other modules (we don't want any unit + tests to fail just because some module in gst-plugins-bad has a broken + plugin_init, for example). Also, we want to only load gst-plugins-good + modules from the locally-built source tree, but not any of the older + gst-plugins-good modules installed. This is usually assured by loading + the ones in the source tree first (by adding that path first to the + right environment variables), but it gets tricky when plugins are + moved, removed, merged, or renamed, or the plugin filename changes. + Note that 'make check' should really work right without doing + 'make install' or uninstalling the old gst-plugins-good package (or + any other gst-plugins-foo package) first. + Enter GST_PLUGIN_LOADING_WHITELIST. This environment variable may + contain source-package@path-prefix pairs separated by the platform + search path separator (G_SEARCHPATH_SEPARATOR_S). The source package + and path prefix are separated by the '@' character.

Previously (ie. before, in + the git version) we would return TRUE in that case and seekable=FALSE, which + is more correct, but causes backwards compatibility problems. (Before that + we would change the format of the query when answering, which was completely + broken since callers don't expect that or check for it). Since the SEEKING + query is a fairly recent addition, not all demuxers, parsers and decoders + implement it yet, in which case any SEEKING query by an application will + just be passed upstream where it will then be handled by basesrc. Now, if + e.g. totem does a SEEKING query for TIME format and we have a demuxer that + doesn't implement the query, basesrc would answer it with seekable=FALSE in + most cases, and totem can only take that as authoritative answer, not knowing + that the demuxer doesn't implement the SEEKING query. To avoid this, we make + basesrc return FALSE to SEEKING queries in unhandled formats. That way + applications like totem can fall back on assuming seekability depending on + whether a duration is available, or somesuch.

This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell command './configure && make && make install' +should configure, build, and install this package. The following +more-detailed instructions are generic; see the 'README' file for +instructions specific to this package. Some packages provide this +'INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The 'configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a 'Makefile' in each directory of the package. +It may also create one or more '.h' files containing system-dependent +definitions. Finally, it creates a shell script 'config.status' that +you can run in the future to recreate the current configuration, and a +file 'config.log' containing compiler output (useful mainly for +debugging 'configure'). + + It can also use an optional file (typically called 'config.cache' and +enabled with '--cache-file=config.cache' or simply '-C') that saves the +results of its tests to speed up reconfiguring. Caching is disabled by +default to prevent problems with accidental use of stale cache files. + + If you need to do unusual things to compile the package, please try +to figure out how 'configure' could check whether to do them, and mail +diffs or instructions to the address given in the 'README' so they can +be considered for the next release. If you are using the cache, and at +some point 'config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file 'configure.ac' (or 'configure.in') is used to create +'configure' by a program called 'autoconf'. You need 'configure.ac' if +you want to change it or regenerate 'configure' using a newer version of +'autoconf'. + + The simplest way to compile this package is: + + 1. 'cd' to the directory containing the package's source code and type + './configure' to configure the package for your system. + + Running 'configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type 'make' to compile the package. + + 3. Optionally, type 'make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type 'make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the 'make install' phase executed with root + privileges. + + 5. Optionally, type 'make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior 'make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing 'make clean'. To also remove the + files that 'configure' created (so you can compile the package for + a different kind of computer), type 'make distclean'. There is + also a 'make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type 'make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide 'make + distcheck', which can by used by developers to test that all other + targets like 'make install' and 'make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the 'configure' script does not know about. Run './configure --help' +for details on some of the pertinent environment variables. + + You can give 'configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here is +an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU 'make'. 'cd' to the +directory where you want the object files and executables to go and run +the 'configure' script. 'configure' automatically checks for the source +code in the directory that 'configure' is in and in '..'. This is known +as a "VPATH" build. + + With a non-GNU 'make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use 'make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple '-arch' options to the +compiler but only a single '-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the 'lipo' tool if you have problems. + +Installation Names +================== + + By default, 'make install' installs the package's commands under +'/usr/local/bin', include files under '/usr/local/include', etc. You +can specify an installation prefix other than '/usr/local' by giving +'configure' the option '--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option '--exec-prefix=PREFIX' to 'configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like '--bindir=DIR' to specify different values for particular +kinds of files. Run 'configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the default +for these options is expressed in terms of '${prefix}', so that +specifying just '--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to 'configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +'make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, 'make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +'${prefix}'. Any directories that were specified during 'configure', +but not in terms of '${prefix}', must each be overridden at install time +for the entire installation to be relocated. The approach of makefile +variable overrides for each directory variable is required by the GNU +Coding Standards, and ideally causes no recompilation. However, some +platforms have known limitations with the semantics of shared libraries +that end up requiring recompilation when using this method, particularly +noticeable in packages that use GNU Libtool. + + The second method involves providing the 'DESTDIR' variable. For +example, 'make install DESTDIR=/alternate/directory' will prepend +'/alternate/directory' before all installation names. The approach of +'DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of '${prefix}' +at 'configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving 'configure' the +option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'. + + Some packages pay attention to '--enable-FEATURE' options to +'configure', where FEATURE indicates an optional part of the package. +They may also pay attention to '--with-PACKAGE' options, where PACKAGE +is something like 'gnu-as' or 'x' (for the X Window System). The +'README' should mention any '--enable-' and '--with-' options that the +package recognizes. + + For packages that use the X Window System, 'configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the 'configure' options '--x-includes=DIR' and +'--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of 'make' will be. For these packages, running './configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with 'make V=1'; while running './configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with 'make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC +is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX 'make' updates targets which have the same time stamps as their +prerequisites, which makes it generally unusable when shipped generated +files such as 'configure' are involved. Use GNU 'make' instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its '' header file. The option '-nodtk' can be used as a +workaround. If GNU CC is not installed, it is therefore recommended to +try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put '/usr/ucb' early in your 'PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in '/usr/bin'. So, if you need '/usr/ucb' +in your 'PATH', put it _after_ '/usr/bin'. + + On Haiku, software installed for all users goes in '/boot/common', +not '/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features 'configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, 'configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +'--build=TYPE' option. TYPE can either be a short name for the system +type, such as 'sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file 'config.sub' for the possible values of each field. If +'config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option '--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with '--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for 'configure' scripts to share, +you can create a site shell script called 'config.site' that gives +default values for variables like 'CC', 'cache_file', and 'prefix'. +'configure' looks for 'PREFIX/share/config.site' if it exists, then +'PREFIX/etc/config.site' if it exists. Or, you can set the +'CONFIG_SITE' environment variable to the location of the site script. +A warning: not all 'configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to 'configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the 'configure' command line, using 'VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified 'gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an +Autoconf limitation. Until the limitation is lifted, you can use this +workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +'configure' Invocation +====================== + + 'configure' recognizes the following options to control how it +operates. + +'--help' +'-h' + Print a summary of all of the options to 'configure', and exit. + +'--help=short' +'--help=recursive' + Print a summary of the options unique to this package's + 'configure', and exit. The 'short' variant lists options used only + in the top level, while the 'recursive' variant lists options also + present in any nested packages. + +'--version' +'-V' + Print the version of Autoconf used to generate the 'configure' + script, and exit. + +'--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally 'config.cache'. FILE defaults to '/dev/null' to + disable caching. + +'--config-cache' +'-C' + Alias for '--cache-file=config.cache'. + +'--quiet' +'--silent' +'-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to '/dev/null' (any error + messages will still be shown). + +'--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + 'configure' can determine that directory automatically. + +'--prefix=DIR' + Use DIR as the installation prefix. *note Installation Names:: for + more details, including other options available for fine-tuning the + installation locations. + +'--no-create' +'-n' + Run the configure checks, but stop before creating any output + files. + +'configure' also accepts some other, not widely useful, options. Run +'configure --help' for more details. diff --git a/MAINTAINERS b/MAINTAINERS new file mode 100644 index 0000000..72aac8e --- /dev/null +++ b/MAINTAINERS @@ -0,0 +1,12 @@ +GStreamer is currently maintained by the consensus of a number +of people, including, but not limited to: + + Jan Schmidt + Wim Taymans + David Schleef + Tim-Philipp Müller + Sebastian Dröge + +Maintainer-related issues should be addressed to: + + gstreamer-devel@lists.freedesktop.org diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..de057c4 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,206 @@ +DISTCHECK_CONFIGURE_FLAGS=--enable-gtk-doc + +# note: keep in sync with configure.ac +ACLOCAL_AMFLAGS = -I m4 -I common/m4 + +aclocaldir = $(datadir)/aclocal +aclocal_DATA = gst-element-check-1.0.m4 + +SUBDIRS = pkgconfig \ + gst libs plugins tests \ + docs \ + po \ + m4 \ + common \ + data + +if BUILD_TOOLS +SUBDIRS += tools +endif + +# These are all the possible subdirs +DIST_SUBDIRS = pkgconfig \ + gst libs plugins tools tests \ + docs \ + po \ + m4 \ + common \ + data + +# include before EXTRA_DIST for win32 assignment +include $(top_srcdir)/common/win32.mak + +EXTRA_DIST = \ + gst-element-check-1.0.m4 \ + configure.ac autogen.sh depcomp \ + MAINTAINERS ABOUT-NLS RELEASE gstreamer.doap \ + scripts/gst-uninstalled \ + $(shell find "$(top_srcdir)" -type f -name meson.build ! -path "$(top_srcdir)/gstreamer-*" ) \ + gst/gstenumtypes.c.template gst/gstenumtypes.h.template \ + libs/gst/controller/controller_mkenum.py \ + meson_options.txt \ + gst/parse/gen_lex.py.in gst/parse/gen_grammar.py.in \ + $(win32) + +DISTCLEANFILES = _stdint.h + +include $(top_srcdir)/common/release.mak +include $(top_srcdir)/common/po.mak + +if GST_GCOV_ENABLED +clean-gcov: + find -name "*.da" -o -name "*.gcov" | xargs rm || true + +clean-bbg: + find -name "*.bbg" -o -name "*.bb" | xargs rm || true + +GCOV_DIRS=gst libs + +## .PHONY so it always rebuilds it +.PHONY: coverage-report.txt + +coverage-report.txt: + BBG_FILES=`find $(GCOV_DIRS) -name "*.bbg"` ;

Coinciding with the 1.14 + release, a new release with the 1.14 API additions is happening. + + +Major new features and changes + +WebRTC support + +There is now basic support for WebRTC in GStreamer in form of a new +webrtcbin element and a webrtc support library. This allows you to build +applications that set up connections with and stream to and from other +WebRTC peers, whilst leveraging all of the usual GStreamer features such +as hardware-accelerated encoding and decoding, OpenGL integration, +zero-copy and embedded platform support. And it's easy to build and +integrate into your application too! + +WebRTC enables real-time communication of audio, video and data with web +browsers and native apps, and it is supported or about to be support by +recent versions of all major browsers and operating systems. + +GStreamer's new WebRTC implementation uses libnice for Interactive +Connectivity Establishment (ICE) to figure out the best way to +communicate with other peers, punch holes into firewalls, and traverse +NATs. + +The implementation is not complete, but all the basics are there, and +the code sticks fairly close to the PeerConnection API. Where +functionality is missing it should be fairly obvious where it needs to +go. + +For more details, background and example code, check out Nirbheek's blog +post _GStreamer has grown a WebRTC implementation_, as well as Matthew's +_GStreamer WebRTC_ talk from last year's GStreamer Conference in Prague. + +New Elements + +- webrtcbin handles the transport aspects of webrtc connections (see + WebRTC section above for more details) + +- New srtsink and srtsrc elements for the Secure Reliable Transport + (SRT) video streaming protocol, which aims to be easy to use whilst + striking a new balance between reliability and latency for low + latency video streaming use cases. More details about SRT and the + implementation in GStreamer in Olivier's blog post _SRT in + GStreamer_. + +- av1enc and av1dec elements providing experimental support for the + next-generation royalty free video AV1 codec, alongside Matroska + support for it. + +- hlssink2 is a rewrite of the existing hlssink element, but unlike + its predecessor hlssink2 takes elementary streams as input and + handles the muxing to MPEG-TS internally. It also leverages + splitmuxsink internally to do the splitting. This allows more + control over the chunk splitting and sizing process and relies less + on the co-operation of an upstream muxer. Different to the old + hlssink it also works with pre-encoded streams and does not require + close interaction with an upstream encoder element. + +- audiolatency is a new element for measuring audio latency end-to-end + and is useful to measure roundtrip latency including both the + GStreamer-internal latency as well as latency added by external + components or circuits. + +- 'fakevideosink is basically a null sink for video data and very + similar to fakesink, only that it will answer allocation queries and + will advertise support for various video-specific things such + GstVideoMeta, GstVideoCropMeta and GstVideoOverlayCompositionMeta + like a normal video sink would. This is useful for throughput + testing and testing the zero-copy path when creating a new pipeline. + +- ipcpipeline: new plugin that allows the splitting of a pipeline into + multiple processes. Usually a GStreamer pipeline runs in a single + process and parallelism is achieved by distributing workloads using + multiple threads. This means that all elements in the pipeline have + access to all the other elements' memory space however, including + that of any libraries used. For security reasons one might therefore + want to put sensitive parts of a pipeline such as DRM and decryption + handling into a separate process to isolate it from the rest of the + pipeline. This can now be achieved with the new ipcpipeline plugin. + Check out George's blog post _ipcpipeline: Splitting a GStreamer + pipeline into multiple processes_ or his lightning talk from last + year's GStreamer Conference in Prague for all the gory details. + +- proxysink and proxysrc are new elements to pass data from one + pipeline to another within the same process, very similar to the + existing inter elements, but not limited to raw audio and video + data. These new proxy elements are very special in how they work + under the hood, which makes them extremely powerful, but also + dangerous if not used with care. The reason for this is that it's + not just data that's passed from sink to src, but these elements + basically establish a two-way wormhole that passes through queries + and events in both directions, which means caps negotiation and + allocation query driven zero-copy can work through this wormhole. + There are scheduling considerations as well: proxysink forwards + everything into the proxysrc pipeline directly from the proxysink + streaming thread. There is a queue element inside proxysrc to + decouple the source thread from the sink thread, but that queue is + not unlimited, so it is entirely possible that the proxysink + pipeline thread gets stuck in the proxysrc pipeline, e.g. when that + pipeline is paused or stops consuming data for some other reason. + This means that one should always shut down down the proxysrc + pipeline before shutting down the proxysink pipeline, for example. + Or at least take care when shutting down pipelines. Usually this is + not a problem though, especially not in live pipelines. For more + information see Nirbheek's blog post _Decoupling GStreamer + Pipelines_, and also check out out the new ipcpipeline plugin for + sending data from one process to another process (see above). + +- lcms is a new LCMS-based ICC color profile correction element + +- openmptdec is a new OpenMPT-based decoder for module music formats, + such as S3M, MOD, XM, IT. It is built on top of a new + GstNonstreamAudioDecoder base class which aims to unify handling of + files which do not operate a streaming model. The wildmidi plugin + has also been revived and is also implemented on top of this new + base class. + +- The curl plugin has gained a new curlhttpsrc element, which is + useful for testing HTTP protocol version 2.0 amongst other things. + +- The msdk plugin has gained a MPEG-2 video decoder(msdkmpeg2dec), VP8 + decoder(msdkvp8dec) and a VC1/WMV decoder(msdkvc1dec) + +Noteworthy new API + +- GstPromise provides future/promise-like functionality. This is used + in the GStreamer WebRTC implementation. + +- GstReferenceTimestampMeta is a new meta that allows you to attach + additional reference timestamps to a buffer. These timestamps don't + have to relate to the pipeline clock in any way. Examples of this + could be an NTP timestamp when the media was captured, a frame + counter on the capture side or the (local) UNIX timestamp when the + media was captured. The decklink elements make use of this. + +- GstVideoRegionOfInterestMeta: it's now possible to attach generic + free-form element-specific parameters to a region of interest meta, + for example to tell a downstream encoder to use certain codec + parameters for a certain region. + +- gst_bus_get_pollfd can be used to obtain a file descriptor for the + bus that can be poll()-ed on for new messages. This is useful for + integration with non-GLib event loops. + +- gst_get_main_executable_path() can be used by wrapper plugins that + need to find things in the directory where the application + executable is located. In the same vein, + GST_PLUGIN_DEPENDENCY_FLAG_PATHS_ARE_RELATIVE_TO_EXE can be used to + signal that plugin dependency paths are relative to the main + executable. + +- pad templates can be told about the GType of the pad subclass of the + pad via newly-added GstPadTemplate API API or the + gst_element_class_add_static_pad_template_with_gtype() convenience + function. gst-inspect-1.0 will use this information to print pad + properties. + +- new convenience functions to iterate over element pads without using + the GstIterator API: gst_element_foreach_pad(), + gst_element_foreach_src_pad(), and gst_element_foreach_sink_pad(). + +- GstBaseSrc and appsrc have gained support for buffer lists: + GstBaseSrc subclasses can use gst_base_src_submit_buffer_list(), and + applications can use gst_app_src_push_buffer_list() to push a buffer + list into appsrc. + +- The GstHarness unit test harness has a couple of new convenience + functions to retrieve all pending data in the harness in form of a + single chunk of memory. + +- GstAudioStreamAlign is a new helper object for audio elements that + handles discontinuity detection and sample alignment. It will align + samples after the previous buffer's samples, but keep track of the + divergence between buffer timestamps and sample position (jitter). + If it exceeds a configurable threshold the alignment will be reset. + This simply factors out code that was duplicated in a number of + elements into a common helper API. + +- The GstVideoEncoder base class implements Quality of Service (QoS) + now. This is disabled by default and must be opted in by setting the + "qos" property, which will make the base class gather statistics + about the real-time performance of the pipeline from downstream + elements (usually sinks that sync the pipeline clock). Subclasses + can then make use of this by checking whether input frames are late + already using gst_video_encoder_get_max_encode_time() If late, they + can just drop them and skip encoding in the hope that the pipeline + will catch up. + +- The GstVideoOverlay interface gained a few helper functions for + installing and handling a "render-rectangle" property on elements + that implement this interface, so that this functionality can also + be used from the command line for testing and debugging purposes. + The property wasn't added to the interface itself as that would + require all implementors to provide it which would not be + backwards-compatible. + +- A new base class, GstNonstreamAudioDecoder for non-stream audio + decoders was added to gst-plugins-bad. This base-class is meant to + be used for audio decoders that require the whole stream to be + loaded first before decoding can start. Examples of this are module + formats (MOD/S3M/XM/IT/etc), C64 SID tunes, video console music + files (GYM/VGM/etc), MIDI files and others. The new openmptdec + element is based on this. + +- Full list of API new in 1.14: +- GStreamer core API new in 1.14 +- GStreamer base library API new in 1.14 +- gst-plugins-base libraries API new in 1.14 +- gst-plugins-bad: no list, mostly GstWebRTC library and new + non-stream audio decoder base class. + +New RTP features and improvements + +- rtpulpfecenc and rtpulpfecdec are new elements that implement + Generic Forward Error Correction (FEC) using Uneven Level Protection + (ULP) as described in RFC 5109. This can be used to protect against + certain types of (non-bursty) packet loss, and important packets + such as those containing codec configuration data or key frames can + be protected with higher redundancy. Equally, packets that are not + particularly important can be given low priority or not be protected + at all. If packets are lost, the receiver can then hopefully restore + the lost packet(s) from the surrounding packets which were received. + This is an alternative to, or rather complementary to, dealing with + packet loss using _retransmission (rtx)_. GStreamer has had + retransmission support for a long time, but Forward Error Correction + allows for different trade-offs: The advantage of Forward Error + Correction is that it doesn't add latency, whereas retransmission + requires at least one more roundtrip to request and hopefully + receive lost packets; Forward Error Correction increases the + required bandwidth however, even in situations where there is no + packet loss at all, so one will typically want to fine-tune the + overhead and mechanisms used based on the characteristics of the + link at the time. + +- New _Redundant Audio Data (RED)_ encoders and decoders for RTP as + per RFC 2198 are also provided (rtpredenc and rtpreddec), mostly for + chrome webrtc compatibility, as chrome will wrap ULPFEC-protected + streams in RED packets, and such streams need to be wrapped and + unwrapped in order to use ULPFEC with chrome. + +- a few new buffer flags for FEC support: + GST_BUFFER_FLAG_NON_DROPPABLE can be used to mark important buffers, + e.g. to flag RTP packets carrying keyframes or codec setup data for + RTP Forward Error Correction purposes, or to prevent still video + frames from being dropped by elements due to QoS. There already is a + GST_BUFFER_FLAG_DROPPABLE. GST_RTP_BUFFER_FLAG_REDUNDANT is used to + signal internally that a packet represents a redundant RTP packet + and used in rtpstorage to hold back the packet and use it only for + recovery from packet loss. Further work is still needed in + payloaders to make use of these. + +- rtpbin now has an option for increasing timestamp offsets gradually: + Sudden large changes to the internal ts_offset may cause timestamps + to move backwards and may also cause visible glitches in media + playback. The new "max-ts-offset-adjustment" and "max-ts-offset" + properties let the application control the rate to apply changes to + ts_offset. There have also been some EOS/BYE handling improvements + in rtpbin. + +- rtpjitterbuffer has a new fast start mode: in many scenarios the + jitter buffer will have to wait for the full configured latency + before it can start outputting packets. The reason for that is that + it often can't know what the sequence number of the first expected + RTP packet is, so it can't know whether a packet earlier than the + earliest packet received will still arrive in future. This behaviour + can now be bypassed by setting the "faststart-min-packets" property + to the number of consecutive packets needed to start, and the jitter + buffer will start output packets as soon as it has N consecutive + packets queued internally. This is particularly useful to get a + first video frame decoded and rendered as quickly as possible. + +- rtpL8pay and rtpL8depay provide RTP payloading and depayloading for + 8-bit raw audio + +New element features + +- playbin3 has gained support or gapless playback via the + "about-to-finish" signal where users can set the uri for the next + item to play. For non-live streams this will be emitted as soon as + the first uri has finished downloading, so with sufficiently large + buffers it is now possible to pre-buffer the next item well ahead of + time (unlike playbin where there would not be a lot of time between + "about-to-finish" emission and the end of the stream). If the stream + format of the next stream is the same as that of the previous + stream, the data will be concatenated via the concat element. + Whether this will result in true gaplessness depends on the + container format and codecs used, there might still be codec-related + gaps between streams with some codecs. + +- tee now does allocation query aggregation, which is important for + zero-copy and efficient data handling, especially for video. Those + who want to drop allocation queries on purpose can use the identity + element's new "drop-allocation" property for that instead. + +- audioconvert now has a "mix-matrix" property, which obsoletes the + audiomixmatrix element. There's also mix matrix support in the audio + conversion and channel mixing API. + +- x264enc: new "insert-vui" property to disable VUI (Video Usability + Information) parameter insertion into the stream, which allows + creation of streams that are compatible with certain legacy hardware + decoders that will refuse to decode in certain combinations of + resolution and VUI parameters; the max. allowed number of B-frames + was also increased from 4 to 16. + +- dvdlpcmdec: has gained support for Blu-Ray audio LPCM. + +- appsrc has gained support for buffer lists (see above) and also seen + some other performance improvements. + +- flvmux has been ported to the GstAggregator base class which means + it can work in defined-latency mode with live input sources and + continue streaming if one of the inputs stops producing data. + +- jpegenc has gained a "snapshot" property just like pngenc to make it + easier to output just a single encoded frame. + +- jpegdec will now handle interlaced MJPEG streams properly and also + handles frames without an End of Image marker better. + +- v4l2: There are now video encoders for VP8, VP9, MPEG4, and H263. + The v4l2 video decoder handles dynamic resolution changes, and the + video4linux device provider now does much faster device probing. The + plugin also no longer uses the libv4l2 library by default, as it has + prevented a lot of interesting use cases like CREATE_BUFS, DMABuf, + usage of TRY_FMT. As the libv4l2 library is totally inactive and not + really maintained, we decided to disable it. This might affect a + small number of cheap/old webcams with custom vendor formats for + which we do not provide conversion in GStreamer. It is possible to + re-enable support for libv4l2 at run-time however, by setting the + environment variable GST_V4L2_USE_LIBV4L2=1. + +- rtspsrc now has support for RTSP protocol version 2.0 as well as + ONVIF audio backchannels (see below for more details). It also + sports a new "accept-certificate" signal for "manually" checking a + TLS certificate for validity. It now also prints RTSP/SDP messages + to the gstreamer debug log instead of stdout. + +- shout2send now uses non-blocking I/O and has a configurable network + operations timeout. + +- splitmuxsink has gained a "split-now" action signal and new + "alignment-threshold" and "use-robust-muxing" properties. If robust + muxing is enabled, it will check and set the muxer's reserved space + properties if present. This is primarily for use with mp4mux's + robust muxing mode. + +- qtmux has a new _prefill recording mode_ which sets up a moov header + with the correct sample positions beforehand, which then allows + software like Adobe Premiere and FinalCut Pro to import the files + while they are still being written to. This only works with constant + framerate I-frame only streams, and for now only support for ProRes + video and raw audio is implemented. Adding support for additional + codecs is just a matter of defining appropriate maximum frame sizes + though. + +- qtmux also supports writing of svmi atoms with stereoscopic video + information now. Trak timescales can be configured on a per-stream + basis using the "trak-timescale" property on the sink pads. Various + new formats can be muxed: MPEG layer 1 and 2, AC3 and Opus, as well + as PNG and VP9. + +- souphttpsrc now does connection sharing by default: it shares its + SoupSession with other elements in the same pipeline via a + GstContext if possible (session-wide settings are all the defaults). + This allows for connection reuse, cookie sharing, etc. Applications + can also force a context to use. In other news, HTTP headers + received from the server are posted as element messages on the bus + now for easier diagnostics, and it's also possible now to use other + types of proxy servers such as SOCKS4 or SOCKS5 proxies, support for + which is implemented directly in gio. Before only HTTP proxies were + allowed. + +- qtmux, mp4mux and matroskamux will now refuse caps changes of input + streams at runtime. This isn't really supported with these + containers (or would have to be implemented differently with a + considerable effort) and doesn't produce valid and spec-compliant + files that will play everywhere. So if you can't guarantee that the + input caps won't change, use a container format that does support on + the fly caps changes for a stream such as MPEG-TS or use + splitmuxsink which can start a new file when the caps change. What + would happen before is that e.g. rtph264depay or rtph265depay would + simply send new SPS/PPS inband even for AVC format, which would then + get muxed into the container as if nothing changed. Some decoders + will handle this just fine, but that's often more luck than by + design. In any case, it's not right, so we disallow it now. + +- matroskamux has Table of Content (TOC) support now (chapters etc.) + and matroskademux TOC support has been improved. matroskademux has + also seen seeking improvements searching for the right cluster and + position. + +- videocrop now uses GstVideoCropMeta if downstream supports it, which + means cropping can be handled more efficiently without any copying. + +- compositor now has support for _crossfade blending_, which can be + used via the new "crossfade-ratio" property on the sink pads. + +- The avwait element has a new "end-timecode" property and posts + "avwait-status" element messages now whenever avwait starts or stops + passing through data (e.g. because target-timecode and end-timecode + respectively have been reached). + +- 'alsamidisrc' element has been broken for many many years and has + now been repaired allowing live capture from your MIDI HW. + +- h265parse and h265parse will try harder to make upstream output the + same caps as downstream requires or prefers, thus avoiding + unnecessary conversion. The parsers also expose chroma format and + bit depth in the caps now. + +- The dtls elements now longer rely on or require the application to + run a GLib main loop that iterates the default main context + (GStreamer plugins should never rely on the application running a + GLib main loop). + +- openh264enc allows to change the encoding bitrate dynamically at + runtime now + +- nvdec is a new plugin for hardware-accelerated video decoding using + the NVIDIA NVDEC API (which replaces the old VDPAU API which is no + longer supported by NVIDIA) + +- The NVIDIA NVENC hardware-accelerated video encoders now support + dynamic bitrate and preset reconfiguration and support the I420 + 4:2:0 video format. It's also possible to configure the gop size via + the new "gop-size" property. + +- The MPEG-TS muxer and demuxer (tsmux, tsdemux) now have support for + JPEG2000 + +- openjpegdec and jpeg2000parse support 2-component images now (gray + with alpha), and jpeg2000parse has gained limited support for + conversion between JPEG2000 stream-formats. (JP2, J2C, JPC) and also + extracts more details such as colorimetry, interlace-mode, + field-order, multiview-mode and chroma siting. + +- The decklink plugin for Blackmagic capture and playback cards have + seen numerous improvements: + +- decklinkaudiosrc and decklinkvideosrc now put hardware reference + timestamp on buffers in form of GstReferenceTimestampMetas. + This can be useful to know on multi-channel cards which frames from + different channels were captured at the same time. + +- decklinkvideosink has gained support for Decklink hardware keying + with two new properties ("keyer-mode" and "keyer-level") to control + the built-in hardware keyer of Decklink cards. + +- decklinkaudiosink has been re-implemented around GstBaseSink instead + of the GstAudioBaseSink base class, since the Decklink APIs don't + fit very well with the GstAudioBaseSink APIs, which used to cause + various problems due to inaccuracies in the clock calculations. + Problems were audio drop-outs and A/V sync going wrong after + pausing/seeking. + +- support for more than 16 devices, without any artificial limit + +- work continued on the msdk plugin for Intel's Media SDK which + enables hardware-accelerated video encoding and decoding on Intel + graphics hardware on Windows or Linux. Added the video memory, + buffer pool, and context/session sharing support which helps to + improve the performance and resource utilization. Rendernode support + is in place which helps to avoid the constraint of having a running + graphics server as DRM-Master. Encoders are exposing a number rate + control algorithms now. More encoder tuning options like + trellis-quantiztion (h264), slice size control (h264), B-pyramid + prediction(h264), MB-level bitrate control, frame partitioning and + adaptive I/B frame insertion were added, and more pixel formats and + video codecs are supported now. The encoder now also handles + force-key-unit events and can insert frame-packing SEIs for + side-by-side and top-bottom stereoscopic 3D video. + +- dashdemux can now do adaptive trick play of certain types of DASH + streams, meaning it can do fast-forward/fast-rewind of normal (non-I + frame only) streams even at high speeds without saturating network + bandwidth or exceeding decoder capabilities. It will keep statistics + and skip keyframes or fragments as needed. See Sebastian's blog post + _DASH trick-mode playback in GStreamer_ for more details. It also + supports webvtt subtitle streams now and has seen improvements when + seeking in live streams. + +- kmssink has seen lots of fixes and improvements in this cycle, + including: + +- Raspberry Pi (vc4) and Xilinx DRM driver support + +- new "render-rectangle" property that can be used from the command + line as well as "display-width" and "display-height", and + "can-scale" properties + +- GstVideoCropMeta support + +Plugin and library moves + +MPEG-1 audio (mp1, mp2, mp3) decoders and encoders moved to -good + +Following the expiration of the last remaining mp3 patents in most +jurisdictions, and the termination of the mp3 licensing program, as well +as the decision by certain distros to officially start shipping full mp3 +decoding and encoding support, these plugins should now no longer be +problematic for most distributors and have therefore been moved from +-ugly and -bad to gst-plugins-good. Distributors can still disable these +plugins if desired. + +In particular these are: + +- mpg123audiodec: an mp1/mp2/mp3 audio decoder using libmpg123 +- lamemp3enc: an mp3 encoder using LAME +- twolamemp2enc: an mp2 encoder using TwoLAME + +GstAggregator moved from -bad to core + +GstAggregator has been moved from gst-plugins-bad to the base library in +GStreamer and is now stable API. + +GstAggregator is a new base class for mixers and muxers that have to +handle multiple input pads and aggregate streams into one output stream. +It improves upon the existing GstCollectPads API in that it is a proper +base class which was also designed with live streaming in mind. +GstAggregator subclasses will operate in a mode with defined latency if +any of the inputs are live streams. This ensures that the pipeline won't +stall if any of the inputs stop producing data, and that the configured +maximum latency is never exceeded. + +GstAudioAggregator, audiomixer and audiointerleave moved from -bad to -base + +GstAudioAggregator is a new base class for raw audio mixers and muxers +and is based on GstAggregator (see above). It provides defined-latency +mixing of raw audio inputs and ensures that the pipeline won't stall +even if one of the input streams stops producing data. + +As part of the move to stabilise the API there were some last-minute API +changes and clean-ups, but those should mostly affect internal elements. + +It is used by the audiomixer element, which is a replacement for +'adder', which did not handle live inputs very well and did not align +input streams according to running time. audiomixer should behave much +better in that respect and generally behave as one would expected in +most scenarios. + +Similarly, audiointerleave replaces the 'interleave' element which did +not handle live inputs or non-aligned inputs very robustly. + +GstAudioAggregator and its subclases have gained support for input +format conversion, which does not include sample rate conversion though +as that would add additional latency. Furthermore, GAP events are now +handled correctly. + +We hope to move the video equivalents (GstVideoAggregator and +compositor) to -base in the next cycle, i.e. for 1.16. + +GStreamer OpenGL integration library and plugin moved from -bad to -base + +The GStreamer OpenGL integration library and opengl plugin have moved +from gst-plugins-bad to -base and are now part of the stable API canon. +Not all OpenGL elements have been moved; a few had to be left behind in +gst-plugins-bad in the new openglmixers plugin, because they depend on +the GstVideoAggregator base class which we were not able to move in this +cycle. We hope to reunite these elements with the rest of their family +for 1.16 though. + +This is quite a milestone, thanks to everyone who worked to make this +happen! + +Qt QML and GTK plugins moved from -bad to -good + +The Qt QML-based qmlgl plugin has moved to -good and provides a +qmlglsink video sink element as well as a qmlglsrc element. qmlglsink +renders video into a QQuickItem, and qmlglsrc captures a window from a +QML view and feeds it as video into a pipeline for further processing. +Both elements leverage GStreamer's OpenGL integration. In addition to +the move to -good the following features were added: + +- A proxy object is now used for thread-safe access to the QML widget + which prevents crashes in corner case scenarios: QML can destroy the + video widget at any time, so without this we might be left with a + dangling pointer. + +- EGL is now supported with the X11 backend, which works e.g. on + Freescale imx6 + +The GTK+ plugin has also moved from -bad to -good. It includes gtksink +and gtkglsink which both render video into a GtkWidget. gtksink uses +Cairo for rendering the video, which will work everywhere in all +scenarios but involves an extra memory copy, whereas gtkglsink fully +leverages GStreamer's OpenGL integration, but might not work properly in +all scenarios, e.g. where the OpenGL driver does not properly support +multiple sharing contexts in different threads; on Linux Nouveau is +known to be broken in this respect, whilst NVIDIA's proprietary drivers +and most other drivers generally work fine, and the experience with +Intel's driver seems to be mixed; some proprietary embedded Linux +drivers don't work; macOS works. + +GstPhysMemoryAllocator interface moved from -bad to -base + +GstPhysMemoryAllocator is a marker interface for allocators with +physical address backed memory. + +Plugin removals + +- the sunaudio plugin was removed, since it couldn't ever have been + built or used with GStreamer 1.0, but no one even noticed in all + these years. + +- the schroedinger-based Dirac encoder/decoder plugin has been + removed, as there is no longer any upstream or anyone else + maintaining it. Seeing that it's quite a fringe codec it seemed best + to simply remove it. + +API removals + +- some MPEG video parser API in the API unstable codecutils library in + gst-plugins-bad was removed after having been deprecated for 5 + years. + + +Miscellaneous changes + +- The video support library has gained support for a few new pixel + formats: +- NV16_10LE32: 10-bit variant of NV16, packed into 32bit words (plus 2 + bits padding) +- NV12_10LE32: 10-bit variant of NV12, packed into 32bit words (plus 2 + bits padding) +- GRAY10_LE32: 10-bit grayscale, packed in 32bit words (plus 2 bits + padding) + +- decodebin, playbin and GstDiscoverer have seen stability + improvements in corner cases such as shutdown while still starting + up or shutdown in error cases (hat tip to the oss-fuzz project). + +- floating reference handling was inconsistent and has been cleaned up + across the board, including annotations. This solves various + long-standing memory leaks in language bindings, which e.g. often + caused elements and pads to be leaked. + +- major gobject-introspection annotation improvements for large parts + of the library API, including nullability of return types and + function parameters, correct types (e.g. strings vs. filenames), + ownership transfer, array length parameters, etc. This allows to use + bigger parts of the GStreamer API to be safely used from dynamic + language bindings (e.g. Python, Javascript) and allows static + bindings (e.g. C#, Rust, Vala) to autogenerate more API bindings + without manual intervention. + +OpenGL integration + +- The GStreamer OpenGL integration library has moved to + gst-plugins-base and is now part of our stable API. + +- new MESA3D GBM BACKEND. On devices with working libdrm support, it + is possible to use Mesa3D's GBM library to set up an EGL context + directly on top of KMS. This makes it possible to use the GStreamer + OpenGL elements without a windowing system if a libdrm- and + Mesa3D-supported GPU is present. + +- Prefer wayland display over X11: As most Wayland compositors support + XWayland, the X11 backend would get selected. + +- gldownload can export dmabufs now, and glupload will advertise + dmabuf as caps feature. + + +Tracing framework and debugging improvements + +- NEW MEMORY RINGBUFFER BASED DEBUG LOGGER, useful for long-running + applications or to retrieve diagnostics when encountering an error. + The GStreamer debug logging system provides in-depth debug logging + about what is going on inside a pipeline. When enabled, debug logs + are usually written into a file, printed to the terminal, or handed + off to a log handler installed by the application. However, at + higher debug levels the volume of debug output quickly becomes + unmanageable, which poses a problem in disk-space or bandwidth + restricted environments or with long-running pipelines where a + problem might only manifest itself after multiple days. In those + situations, developers are usually only interested in the most + recent debug log output. The new in-memory ringbuffer logger makes + this easy: just installed it with gst_debug_add_ring_buffer_logger() + and retrieve logs with gst_debug_ring_buffer_logger_get_logs() when + needed. It is possible to limit the memory usage per thread and set + a timeout to determine how long messages are kept around. It was + always possible to implement this in the application with a custom + log handler of course, this just provides this functionality as part + of GStreamer. + +- 'fakevideosink is a null sink for video data that advertises + video-specific metas and behaves like a video sink. See above for + more details. + +- gst_util_dump_buffer() prints the content of a buffer to stdout. + +- gst_pad_link_get_name() and gst_state_change_get_name() print pad + link return values and state change transition values as strings. + +- The LATENCY TRACER has seen a few improvements: trace records now + contain timestamps which is useful to plot things over time, and + downstream synchronisation time is now excluded from the measured + values. + +- Miniobject refcount tracing and logging was not entirley + thread-safe, there were duplicates or missing entries at times. This + has now been made reliable. + +- The netsim element, which can be used to simulate network jitter, + packet reordering and packet loss, received new features and + improvements: it can now also simulate network congestion using a + token bucket algorithm. This can be enabled via the "max-kbps" + property. Packet reordering can be disabled now via the + "allow-reordering" property: Reordering of packets is not very + common in networks, and the delay functions will always introduce + reordering if delay > packet-spacing, so by setting + "allow-reordering" to FALSE you guarantee that the packets are in + order, while at the same time introducing delay/jitter to them. By + using the new "delay-distribution" property the user can control how + the delay applied to delayed packets is distributed: This is either + the uniform distribution (as before) or the normal distribution; in + addition there is also the gamma distribution which simulates the + delay on wifi networks better. + + +Tools + +- gst-inspect-1.0 now prints pad properties for elements that have pad + subclasses with special properties, such as compositor or + audiomixer. This only works for elements that use the newly-added + GstPadTemplate API API or the + gst_element_class_add_static_pad_template_with_gtype() convenience + function to tell GStreamer about the special pad subclass. + +- gst-launch-1.0 now generates a gstreamer pipeline diagram (.dot + file) whenever SIGHUP is sent to it on Linux/*nix systems. + +- gst-discoverer-1.0 can now analyse live streams such as rtsp:// URIs + + +GStreamer RTSP server + +- Initial support for RTSP protocol version 2.0 was added, which is to + the best of our knowledge the first RTSP 2.0 implementation ever! + +- ONVIF audio backchannel support. This is an extension specified by + ONVIF that allows RTSP clients (e.g. a control room operator) to + send audio back to the RTSP server (e.g. an IP camera). + Theoretically this could have been done also by using the RECORD + method of the RTSP protocol, but ONVIF chose not to do that, so the + backchannel is set up alongside the other streams. Format + negotiation needs to be done out of band, if needed. Use the new + ONVIF-specific subclasses GstRTSPOnvifServer and + GstRTSPOnvifMediaFactory to enable this functionality. + +- The internal server streaming pipeline is now dynamically + reconfigured on PLAY based on the transports needed. This means that + the server no longer adds the pipeline plumbing for all possible + transports from the start, but only if needed as needed. This + improves performance and memory footprint. + +- rtspclientsink has gained an "accept-certificate" signal for + manually checking a TLS certificate for validity. + +- Fix keep-alive/timeout issue for certain clients using TCP + interleave as transport who don't do keep-alive via some other + method such as periodic RTSP OPTION requests. We now put netaddress + metas on the packets from the TCP interleaved stream, so can map + RTCP packets to the right stream in the server and can handle them + properly. + +- Language bindings improvements: in general there were quite a few + improvements in the gobject-introspection annotations, but we also + extended the permissions API which was not usable from bindings + before. + +- Fix corner case issue where the wrong mount point was found when + there were multiple mount points with a common prefix. + + +GStreamer VAAPI + +- Improve DMABuf's usage, both upstream and dowstream, and + memory:DMABuf caps feature is also negotiated when the dmabuf-based + buffer cannot be mapped onto user-space. + +- VA initialization was fixed when it is used in headless systems. + +- VA display sharing, through GstContext, among the pipeline, has been + improved, adding the possibility to the application share its VA + display (external display) via gst.vaapi.app.Display context. + +- VA display cache was removed. + +- libva's log messages are now redirected into the GStreamer log + handler. + +- Decoders improved their upstream re-negotiation by avoiding to + re-instantiate the internal decoder if stream caps are compatible + with the previous one. + +- When downstream doesn't support GstVideoMeta and the decoded frames + don't have standard strides, they are copied onto system + memory-based buffers. + +- H.264 decoder has a low-latency property, for live streams which + doesn't conform the H.264 specification but still it is required to + push the frames to downstream as soon as possible. + +- As part of the Google Summer of Code 2017 the H.264 decoder drops + MVC and SVC frames when base-only property is enabled. + +- Added support for libva-2.0 (VA-API 1.0). + +- H.264 and H.265 encoders handle Region-Of-Interest metas by adding a + delta-qp for every rectangle within the frame specified by those + metas. + +- Encoders for H.264 and H.265 set the media profile by the downstream + caps. + +- H.264 encoder inserts an AU delimiter for each encoded frame when + aud property is enabled (it is only available for certain drivers + and platforms). + +- H.264 encoder supports for P and B hierarchical prediction modes. + +- All encoders handles a quality-level property, which is a number + from 1 to 8, where a lower number means higher quality, but slower + processing, and vice-versa. + +- VP8 and VP9 encoders support constant bit-rate mode (CBR). + +- VP8, VP9 and H.265 encoders support variable bit-rate mode (VBR). + +- Resurrected GstGLUploadTextureMeta handling for EGL backends. + +- H.265 encoder can configure its number of reference frames via the + refs property. + +- Add H.264 encoder mbbrc property, which controls the macro-block + bitrate as auto, on or off. + +- Add H.264 encoder temporal-levels property, to select the number of + temporal levels to be included. + +- Add to H.264 and H.265 encoders the properties qp-ip and qp-ib, to + handle the QP (quality parameter) difference between the I and P + frames, and the I and B frames, respectively. + +- vaapisink was demoted to marginal rank on Wayland because COGL + cannot display YUV surfaces. + +More details in Víctor's blog post _GStreamer VA-API 1.14: what’s new?_. + + +GStreamer Editing Services and NLE + +- Handle crossfade in complex scenarios by using the new + compositorpad::crossfade-ratio property + +- Add API allowing to stop using proxies for clips in the timeline + +- Allow management of none square pixel aspect ratios by allowing + application to deal with them in the way they want + +- Misc fixes around the timeline editing API + + +GStreamer validate + +- Handle running scenarios on live pipelines (in the "content sense", + not the GStreamer one) + +- Implement RTSP support with a basic server based on gst-rtsp-server, + and add RTSP 1.0 and 2.0 integration tests + +- Implement a plugin that allows users to implement configurable + tests. It currently can check if a particular element is added a + configurable number of time in the pipeline. In the future that + plugin should allow us to implement specific tests of any kind in a + descriptive way + +- Add a verbosity configuration which behaves in a similare way as the + gst-launch-1.0 verbose flags allowing the informations to be + outputed on any running pipeline when enabling GstValidate. + +- Misc optimization in the launcher, making the tests run much faster. + + +GStreamer C# bindings + +- Port to the meson build system, autotools support has been removed + +- Use a new GlibSharp version, set as a meson subproject + +- Update wrapped API to GStreamer 1.14 + +- Removed the need for "glue" code + +- Provide a nuget + +- Misc API fixes + + +Build and Dependencies + +- the new WebRTC support in gst-plugins-bad depends on the GStreamer + elements that ship as part of libnice, and libnice version 1.1.14 is + required. Also the dtls and srtp plugins. + +- gst-plugins-bad no longer depends on the libschroedinger Dirac codec + library. + +- The srtp plugin can now also be built against libsrtp2. + +- some plugins and libraries have moved between modules, see the + _Plugin and_ _library moves_ section above, and their respective + dependencies have moved with them of course, e.g. the GStreamer + OpenGL integration support library and plugin is now in + gst-plugins-base, and mpg123, LAME and twoLAME based audio decoder + and encoder plugins are now in gst-plugins-good. + +- Unify static and dynamic plugin interface and remove plugin specific + static build option: Static and dynamic plugins now have the same + interface. The standard --enable-static/--enable-shared toggle is + sufficient. This allows building static and shared plugins from the + same object files, instead of having to build everything twice. + +- The default plugin entry point has changed. This will only affect + plugins that are recompiled against new GStreamer headers. Binary + plugins using the old entry point will continue to work. However, + plugins that are recompiled must have matching plugin names in + GST_PLUGIN_DEFINE and filenames, as the plugin entry point for + shared plugins is now deduced from the plugin filename. This means + you can no longer have a plugin called foo living in a file called + libfoobar.so or such, the plugin filename needs to match. This might + cause problems with some external third party plugin modules when + they get rebuilt against GStreamer 1.14. + + +Note to packagers and distributors + +A number of libraries, APIs and plugins moved between modules and/or +libraries in different modules between version 1.12.x and 1.14.x, see +the _Plugin and_ _library moves_ section above. Some APIs have seen +minor ABI changes in the course of moving them into the stable APIs +section. + +This means that you should try to ensure that all major GStreamer +modules are synced to the same major version (1.12 or 1.13/1.14) and can +only be upgraded in lockstep, so that your users never end up with a mix +of major versions on their system at the same time, as this may cause +breakages. + +Also, plugins compiled against >= 1.14 headers will not load with +GStreamer <= 1.12 owing to a new plugin entry point (but plugin binaries +built against older GStreamer versions will continue to load with newer +versions of GStreamer of course). + +There is also a small structure size related ABI breakage introduced in +the gst-plugins-bad codecparsers library between version 1.13.90 and +1.13.91. This should "only" affect gstreamer-vaapi, so anyone who ships +the release candidates is advised to upgrade those two modules at the +same time. + + +Platform-specific improvements + +Android + +- ahcsrc (Android camera source) does autofocus now + +macOS and iOS + +- no major changes in macOS and iOS support, only bugfixes + +Windows + +- The GStreamer wasapi plugin was rewritten and should not only be + usable now, but in top shape and suitable for low-latency use cases. + The Windows Audio Session API (WASAPI) is Microsoft's most modern + method for talking with audio devices, and now that the wasapi + plugin is up to scratch it is preferred over the directsound plugin. + The ranks of the wasapisink and wasapisrc elements have been updated + to reflect this. Further improvements include: + +- support for more than 2 channels + +- a new "low-latency" property to enable low-latency operation (which + should always be safe to enable) + +- support for the AudioClient3 API which is only available on Windows + 10: in wasapisink this will be used automatically if available; in + wasapisrc it will have to be enabled explicitly via the + "use-audioclient3" property, as capturing audio with low latency and + without glitches seems to require setting the realtime priority of + the entire pipeline to "critical", which cannot be done from inside + the element, but has to be done in the application. + +- set realtime thread priority to avoid glitches + +- allow opening devices in exclusive mode, which provides much lower + latency compared to shared mode where WASAPI's engine period is + 10ms. This can be activated via the "exclusive" property. + +- Also see Nirbheek's blog post _Low Latency Audio on Windows with + GStreamer_. + +- There are now GstDeviceProvider implementations for the wasapi and + directsound plugins, so it's now possible to discover both audio + sources and audio sinks on Windows via the GstDeviceMonitor API + +- debug log timestamps are now higher granularity owing to + g_get_monotonic_time() now being used as fallback in + gst_utils_get_timestamp().

Also, distributors have brought up issues about the legal status +of some of the plug-ins we ship. To remedy this, we've divided the previous +set of available plug-ins into four modules: + +- gst-plugins-base: a small and fixed set of plug-ins, covering a wide range + of possible types of elements; these are continuously kept up-to-date + with any core changes during the development series. + + - We believe distributors can safely ship these plug-ins. + - People writing elements should base their code on these elements. + - These elements come with examples, documentation, and regression tests. + +- gst-plugins-good: a set of plug-ins that we consider to have good quality + code, correct functionality, our preferred license (LGPL for the plug-in + code, LGPL or LGPL-compatible for the supporting library). + + - We believe distributors can safely ship these plug-ins. + - People writing elements should base their code on these elements. + +- gst-plugins-ugly: a set of plug-ins that have good quality and correct + functionality, but distributing them might pose problems. The license + on either the plug-ins or the supporting libraries might not be how we'd + like. The code might be widely known to present patent problems. + + - Distributors should check if they want/can ship these plug-ins. + - People writing elements should base their code on these elements. + +- gst-plugins-bad: a set of plug-ins that aren't up to par compared to the + rest. They might be close to being good quality, but they're missing + something - be it a good code review, some documentation, a set of tests, + a real live maintainer, or some actual wide use. + If the blanks are filled in they might be upgraded to become part of + either gst-plugins-good or gst-plugins-ugly, depending on the other factors. + + - If the plug-ins break, you can't complain - instead, you can fix the + problem and send us a patch, or bribe someone into fixing them for you. + - New contributors can start here for things to work on. + +PLATFORMS +--------- + +- Linux is of course fully supported +- FreeBSD is reported to work; other BSDs should work too +- Solaris is reported to work; a specific sunaudiosink plugin has been written +- MacOSX works, binary 1.x packages can be built using the cerbero build tool +- Windows works; binary 1.x packages can be built using the cerbero build tool + - MSys/MinGW builds + - Microsoft Visual Studio builds are not yet available or supported +- Android works, binary 1.x packages can be built using the cerbero build tool +- iOS works + +INSTALLING FROM PACKAGES +------------------------ + +You should always prefer installing from packages first. GStreamer is +well-maintained for a number of distributions, including Fedora, Debian, +Ubuntu, Mandrake, Gentoo, ... + +Only in cases where you: +- want to hack on GStreamer +- want to verify that a bug has been fixed +- do not have a sane distribution +should you choose to build from source tarballs or git. + +Find more information about the various packages at +http://gstreamer.freedesktop.org/download/ + +COMPILING FROM SOURCE TARBALLS +------------------------------ + +- again, make sure that you really need to install from source ! + If GStreamer is one of your first projects ever that you build from source, + consider taking on an easier project. + +- check output of ./configure --help to see if any options apply to you +- run + ./configure + make + + to build GStreamer. +- if you want to install it (not required, but what you usually want to do), run + make install + +- try out a simple test: + gst-launch -v fakesrc num_buffers=5 ! fakesink + (If you didn't install GStreamer, prefix gst-launch with tools/) + + If it outputs a bunch of messages from fakesrc and fakesink, everything is + ok. + + If it did not work, keep in mind that you might need to adjust the + PATH and/or LD_LIBRARY_PATH environment variables to make the system + find GStreamer in the prefix where you installed (by default that is /usr/local). + +- After this, you're ready to install gst-plugins, which will provide the + functionality you're probably looking for by now, so go on and read + that README. + +COMPILING FROM GIT +------------------ + +When building from git sources, you will need to run autogen.sh to generate +the build system files. + +You will need a set of additional tools typical for building from git, +including: +- autoconf +- automake +- libtool + +autogen.sh will check for recent enough versions and complain if you don't have +them. You can also specify specific versions of automake and autoconf with +--with-automake and --with-autoconf + +Check autogen.sh options by running autogen.sh --help + +autogen.sh can pass on arguments to configure + +When you have done this once, you can use autoregen.sh to re-autogen with +the last passed options as a handy shortcut. Use it. + +After the autogen.sh stage, you can follow the directions listed in +"COMPILING FROM SOURCE" + +You can also run your whole git stack uninstalled in your home directory, +so that you can quickly test changes without affecting your system setup or +interfering with GStreamer installed from packages. Many GStreamer developers +use an uninstalled setup for their work. + +There is a 'create-uninstalled-setup.sh' script in + + http://cgit.freedesktop.org/gstreamer/gstreamer/tree/scripts/ + +to easily create an uninstalled setup from scratch. + + +PLUG-IN DEPENDENCIES AND LICENSES +--------------------------------- + +GStreamer is developed under the terms of the LGPL (see LICENSE file for +details). Some of our plug-ins however rely on libraries which are available +under other licenses. This means that if you are distributing an application +which has a non-GPL compatible license (for instance a closed-source +application) with GStreamer, you have to make sure not to distribute GPL-linked +plug-ins. + +When using GPL-linked plug-ins, GStreamer is for all practical reasons +under the GPL itself. + +HISTORY +------- + +The fundamental design comes from the video pipeline at Oregon Graduate +Institute, as well as some ideas from DirectMedia. It's based on plug-ins that +will provide the various codec and other functionality. The interface +hopefully is generic enough for various companies (ahem, Apple) to release +binary codecs for Linux, until such time as they get a clue and release the +source. diff --git a/RELEASE b/RELEASE new file mode 100644 index 0000000..58b04f2 --- /dev/null +++ b/RELEASE @@ -0,0 +1,84 @@ +This is GStreamer core 1.14.1. + +The GStreamer team is pleased to announce a new bug-fix release in the +stable 1.x API series of your favourite cross-platform multimedia framework! + +The 1.14 release series adds new features on top of the 1.12 series and is +part of the API and ABI-stable 1.x release series of the GStreamer multimedia +framework. + +Full release notes can be found at: + + https://gstreamer.freedesktop.org/releases/1.14/ + +Binaries for Android, iOS, Mac OS X and Windows will be provided shortly +after the release. + +This module will not be very useful by itself and should be used in conjunction +with other GStreamer modules for a complete multimedia experience. + + - gstreamer: provides the core GStreamer libraries and some generic plugins + + - gst-plugins-base: a basic set of well-supported plugins and additional + media-specific GStreamer helper libraries for audio, + video, rtsp, rtp, tags, OpenGL, etc. + + - gst-plugins-good: a set of well-supported plugins under our preferred + license + + - gst-plugins-ugly: a set of well-supported plugins which might pose + problems for distributors + + - gst-plugins-bad: a set of plugins of varying quality that have not made + their way into one of core/base/good/ugly yet, for one + reason or another.

should start by going through our FAQ at +http://gstreamer.freedesktop.org/data/doc/gstreamer/head/faq/html/ + +There is more documentation; go to +http://gstreamer.freedesktop.org/documentation +

+GStreamer 1.0 series +-------------------- + +Starring + + GSTREAMER + +The core around which all other modules revolve. Base functionality and +libraries, some essential elements, documentation, and testing. + + BASE + +A well-groomed and well-maintained collection of GStreamer plug-ins and +elements, spanning the range of possible types of elements one would want +to write for GStreamer. + +And introducing, for the first time ever, on the development screen ... + + THE GOOD + + --- "Such ingratitude. After all the times I've saved your life." + +A collection of plug-ins you'd want to have right next to you on the +battlefield. Shooting sharp and making no mistakes, these plug-ins have it +all: good looks, good code, and good licensing. Documented and dressed up +in tests. If you're looking for a role model to base your own plug-in on, +here it is. + +If you find a plot hole or a badly lip-synced line of code in them, +let us know - it is a matter of honour for us to ensure Blondie doesn't look +like he's been walking 100 miles through the desert without water. + + THE UGLY + + --- "When you have to shoot, shoot. Don't talk." + +There are times when the world needs a color between black and white. +Quality code to match the good's, but two-timing, backstabbing and ready to +sell your freedom down the river. These plug-ins might have a patent noose +around their neck, or a lock-up license, or any other problem that makes you +think twice about shipping them. + +We don't call them ugly because we like them less. Does a mother love her +son less because he's not as pretty as the other ones ? No - she commends +him on his great personality. These plug-ins are the life of the party. +And we'll still step in and set them straight if you report any unacceptable +behaviour - because there are two kinds of people in the world, my friend: +those with a rope around their neck and the people who do the cutting. + + THE BAD + + --- "That an accusation?" + +No perfectly groomed moustache or any amount of fine clothing is going to +cover up the truth - these plug-ins are Bad with a capital B. +They look fine on the outside, and might even appear to get the job done, but +at the end of the day they're a black sheep. Without a golden-haired angel +to watch over them, they'll probably land in an unmarked grave at the final +showdown. + +Don't bug us about their quality - exercise your Free Software rights, +patch up the offender and send us the patch on the fastest steed you can +steal from the Confederates. Because you see, in this world, there's two +kinds of people, my friend: those with loaded guns and those who dig. +You dig. + +The Lowdown +----------- + + --- "I've never seen so many plug-ins wasted so badly." + +GStreamer Plug-ins has grown so big that it's hard to separate the wheat from +the chaff. Also, distributors have brought up issues about the legal status +of some of the plug-ins we ship. To remedy this, we've divided the previous +set of available plug-ins into four modules: + +- gst-plugins-base: a small and fixed set of plug-ins, covering a wide range + of possible types of elements; these are continuously kept up-to-date + with any core changes during the development series. + + - We believe distributors can safely ship these plug-ins. + - People writing elements should base their code on these elements. + - These elements come with examples, documentation, and regression tests. + +- gst-plugins-good: a set of plug-ins that we consider to have good quality + code, correct functionality, our preferred license (LGPL for the plug-in + code, LGPL or LGPL-compatible for the supporting library). + + - We believe distributors can safely ship these plug-ins. + - People writing elements should base their code on these elements. + +- gst-plugins-ugly: a set of plug-ins that have good quality and correct + functionality, but distributing them might pose problems. The license + on either the plug-ins or the supporting libraries might not be how we'd + like. The code might be widely known to present patent problems. + + - Distributors should check if they want/can ship these plug-ins. + - People writing elements should base their code on these elements. + +- gst-plugins-bad: a set of plug-ins that aren't up to par compared to the + rest. They might be close to being good quality, but they're missing + something - be it a good code review, some documentation, a set of tests, + a real live maintainer, or some actual wide use. + If the blanks are filled in they might be upgraded to become part of + either gst-plugins-good or gst-plugins-ugly, depending on the other factors. + + - If the plug-ins break, you can't complain - instead, you can fix the + problem and send us a patch, or bribe someone into fixing them for you. + - New contributors can start here for things to work on. + +PLATFORMS +--------- + +- Linux is of course fully supported +- FreeBSD is reported to work; other BSDs should work too +- Solaris is reported to work; a specific sunaudiosink plugin has been written +- MacOSX works, binary 1.x packages can be built using the cerbero build tool +- Windows works; binary 1.x packages can be built using the cerbero build tool + - MSys/MinGW builds + - Microsoft Visual Studio builds are not yet available or supported +- Android works, binary 1.x packages can be built using the cerbero build tool +- iOS works + +INSTALLING FROM PACKAGES +------------------------ + +You should always prefer installing from packages first. GStreamer is +well-maintained for a number of distributions, including Fedora, Debian, +Ubuntu, Mandrake, Gentoo, ... + +Only in cases where you: +- want to hack on GStreamer +- want to verify that a bug has been fixed +- do not have a sane distribution +should you choose to build from source tarballs or git. + +Find more information about the various packages at +http://gstreamer.freedesktop.org/download/ + +COMPILING FROM SOURCE TARBALLS +------------------------------ + +- again, make sure that you really need to install from source ! + If GStreamer is one of your first projects ever that you build from source, + consider taking on an easier project. + +- check output of ./configure --help to see if any options apply to you +- run + ./configure + make + + to build GStreamer. +- if you want to install it (not required, but what you usually want to do), run + make install + +- try out a simple test: + gst-launch -v fakesrc num_buffers=5 ! fakesink + (If you didn't install GStreamer, prefix gst-launch with tools/) + + If it outputs a bunch of messages from fakesrc and fakesink, everything is + ok. + + If it did not work, keep in mind that you might need to adjust the + PATH and/or LD_LIBRARY_PATH environment variables to make the system + find GStreamer in the prefix where you installed (by default that is /usr/local). + +- After this, you're ready to install gst-plugins, which will provide the + functionality you're probably looking for by now, so go on and read + that README. + +COMPILING FROM GIT +------------------ + +When building from git sources, you will need to run autogen.sh to generate +the build system files. + +You will need a set of additional tools typical for building from git, +including: +- autoconf +- automake +- libtool + +autogen.sh will check for recent enough versions and complain if you don't have +them. You can also specify specific versions of automake and autoconf with +--with-automake and --with-autoconf + +Check autogen.sh options by running autogen.sh --help + +autogen.sh can pass on arguments to configure + +When you have done this once, you can use autoregen.sh to re-autogen with +the last passed options as a handy shortcut. Use it. + +After the autogen.sh stage, you can follow the directions listed in +"COMPILING FROM SOURCE" + +You can also run your whole git stack uninstalled in your home directory, +so that you can quickly test changes without affecting your system setup or +interfering with GStreamer installed from packages. Many GStreamer developers +use an uninstalled setup for their work. + +There is a 'create-uninstalled-setup.sh' script in + + http://cgit.freedesktop.org/gstreamer/gstreamer/tree/scripts/ + +to easily create an uninstalled setup from scratch. + + +PLUG-IN DEPENDENCIES AND LICENSES +--------------------------------- + +GStreamer is developed under the terms of the LGPL (see LICENSE file for +details). Some of our plug-ins however rely on libraries which are available +under other licenses. This means that if you are distributing an application +which has a non-GPL compatible license (for instance a closed-source +application) with GStreamer, you have to make sure not to distribute GPL-linked +plug-ins. + +When using GPL-linked plug-ins, GStreamer is for all practical reasons +under the GPL itself. + +HISTORY +------- + +The fundamental design comes from the video pipeline at Oregon Graduate +Institute, as well as some ideas from DirectMedia. It's based on plug-ins that +will provide the various codec and other functionality. The interface +hopefully is generic enough for various companies (ahem, Apple) to release +binary codecs for Linux, until such time as they get a clue and release the +source. diff --git a/common/c-to-xml.py b/common/c-to-xml.py new file mode 100644 index 0000000..7a7a35b --- /dev/null +++ b/common/c-to-xml.py @@ -0,0 +1,36 @@ +# -*- Mode: Python -*- +# vi:si:et:sw=4:sts=4:ts=4 + +""" +Convert a C program to valid XML to be included in docbook +""" + +from __future__ import print_function, unicode_literals + +import sys +import os +from xml.sax import saxutils + +def main(): + if len(sys.argv) == 1: + sys.stderr.write("Please specify a source file to convert") + sys.exit(1) + source = sys.argv[1] + + if not os.path.exists(source): + sys.stderr.write("%s does not exist.\n" % source) + sys.exit(1) + + content = open(source, "r").read() + + # print header + print ('') + print ('') + print () + print ('') + + # print content + print (saxutils.escape(content)) + print ('') + +main() diff --git a/common/check-exports b/common/check-exports new file mode 100755 index 0000000..8d617ff --- /dev/null +++ b/common/check-exports @@ -0,0 +1,54 @@ +#!/bin/sh +# check-exports +# +# quick'n'dirty script that retrieves the list of exported symbols of a given +# library using 'nm', and compares that against the list of symbols-to-export +# of our win32/common/libfoo.def files. + +if [ $# -ne 2 ];

+# Function    : UpdateFileIfChanged
+# Description : Compares the old version of the file with the new version and
+#                if the file has changed it moves the new version into the old
+#                versions place. This is used so we only change files if
+#                needed, so we can do proper dependency tracking and we don't
+#                needlessly check files into version control systems that haven't
+#               changed.
+#                It returns 0 if the file hasn't changed, and 1 if it has.
+# Arguments   : $old_file - the pathname of the old file.
+#                $new_file - the pathname of the new version of the file.
+#                $make_backup - 1 if a backup of the old file should be kept.
+#                        It will have the .bak suffix added to the file name.

+#
+# SYNOPSIS
+#
+#   AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])]
+#
+# DESCRIPTION
+#
+#   the "ISO C9X: 7.18 Integer types " section requires the
+#   existence of an include file  that defines a set of
+#   typedefs, especially uint8_t,int32_t,uintptr_t. Many older
+#   installations will not provide this file, but some will have the
+#   very same definitions in . In other enviroments we can
+#   use the inet-types in  which would define the typedefs
+#   int8_t and u_int8_t respectivly.
+#
+#   This macros will create a local "_stdint.h" or the headerfile given
+#   as an argument. In many cases that file will just "#include
+#   " or "#include ", while in other environments
+#   it will provide the set of basic 'stdint's definitions/typedefs:
+#
+#     int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
+#     int_least32_t.. int_fast32_t.. intmax_t
+#
+#   which may or may not rely on the definitions of other files, or
+#   using the AC_CHECK_SIZEOF macro to determine the actual sizeof each
+#   type.
+#
+#   if your header files require the stdint-types you will want to
+#   create an installable file mylib-int.h that all your other
+#   installable header may include. So if you have a library package
+#   named "mylib", just use
+#
+#        AX_CREATE_STDINT_H(mylib-int.h)
+#
+#   in configure.ac and go to install that very header file in
+#   Makefile.am along with the other headers (mylib.h) - and the
+#   mylib-specific headers can simply use "#include " to
+#   obtain the stdint-types.
+#
+#   Remember, if the system already had a valid , the
+#   generated file will include it directly. No need for fuzzy
+#   HAVE_STDINT_H things... (oops, GCC 4.2.x has deliberatly disabled
+#   its stdint.h for non-c99 compilation and the c99-mode is not the
+#   default. Therefore this macro will not use the compiler's stdint.h
+#   - please complain to the GCC developers).

+# SYNOPSIS
+#
+#   AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+#   This macro figures out how to build C programs using POSIX threads. It
+#   sets the PTHREAD_LIBS output variable to the threads library and linker
+#   flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+#   flags that are needed. (The user can also force certain compiler
+#   flags/libs to be tested by setting these environment variables.)
+#
+#   Also sets PTHREAD_CC to any special C compiler that is needed for
+#   multi-threaded programs (defaults to the value of CC otherwise). (This
+#   is necessary on AIX to use the special cc_r compiler alias.)
+#
+#   NOTE: You are assumed to not only compile your program with these flags,
+#   but also to link with them as well. For example, you might link with
+#   $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+#   If you are only building threaded programs, you may wish to use these
+#   variables in your default LIBS, CFLAGS, and CC:
+#
+#     LIBS="$PTHREAD_LIBS $LIBS"
+#     CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
+#     CC="$PTHREAD_CC"
+#
+#   In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
+#   has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to
+#   that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
+#
+#   Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
+#   PTHREAD_PRIO_INHERIT symbol is defined when compiling with
+#   PTHREAD_CFLAGS.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a threads library
+#   is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
+#   is not found. If ACTION-IF-FOUND is not specified, the default action
+#   will define HAVE_PTHREAD.
+#
+#   Please let the authors know if this macro fails on any platform, or if
+#   you have any other suggestions or comments. This macro was based on work
+#   by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
+#   from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
+#   Alejandro Forero Cuervo to the autoconf macro repository. We are also
+#   grateful for the helpful feedback of numerous users.

+dnl
+dnl This macro adds a command line argument to allow the user to enable
+dnl or disable a feature, and if the feature is enabled, performs a supplied
+dnl test to check if the feature is available.
+dnl
+dnl The test should define HAVE_ to "yes" or "no" depending
+dnl on whether the feature is available.
+dnl
+dnl The macro will set USE_ to "yes" or "no" depending on
+dnl whether the feature is to be used.
+dnl Thomas changed this, so that when USE_ was already set
+dnl to no, then it stays that way.
+dnl
+dnl The macro will call AM_CONDITIONAL(USE_, ...) to allow
+dnl the feature to control what is built in Makefile.ams.  If you want
+dnl additional actions resulting from the test, you can add them with the
+dnl ACTION-IF-USE and ACTION-IF-NOTUSE parameters.
+dnl
+dnl FEATURE-NAME        is the name of the feature, and should be in
+dnl                     purely upper case characters.
+dnl FEATURE-DESCRIPTION is used to describe the feature in help text for
+dnl                     the command line argument.
+dnl DEPENDENT-PLUGINS   lists any plug-ins which depend on this feature.
+dnl TEST-FOR-FEATURE    is a test which sets HAVE_ to "yes"
+dnl                     or "no" depending on whether the feature is
+dnl                     available.
+dnl DISABLE-BY-DEFAULT  if "disabled", the feature is disabled by default,
+dnl                     if any other value, the feature is enabled by default.
+dnl ACTION-IF-USE       any extra actions to perform if the feature is to be
+dnl                     used.
+dnl ACTION-IF-NOTUSE    any extra actions to perform if the feature is not to

+\`configure' configures GStreamer 1.14.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
+  --libdir=DIR            object code libraries [EPREFIX/lib]
+  --includedir=DIR        C header files [PREFIX/include]
+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
+  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
+  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## This next piece of magic avoids the "deleted header file" problem.
+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH
+## to the object.  Take care to not repeat it in the output.

+GStreamer documentation notes
+
+IMPORTANT
+=========
+
+Please make sure you've read and understood everything in this file
+before you try changing documentation.
+
+Some of the docbook-related bits in this README might be out of date now that
+quite a bit of the documentation has moved into the gst-docs repository.
+
+OVERVIEW
+========
+
+GStreamer has two sets of documentation that we maintain:
+* API references, using gtk-doc (gstreamer, gstreamer-libs)
+* FAQ / Application Development Manual / Plugin Writer's Guide / Tutorials -
+  these are maintained in markdown format and live in the gst-docs repository.
+
+DOCBOOK NOTES
+=============
+
+OK, I've grown so tired of having to coax the docs to build every time I
+get round to it that I've decided to note down some of the things that
+are important to know.
+
+OVERVIEW
+--------
+* Our documentation should all be Docbook/XML.  No SGML.
+* The source for the documentation is:
+  - one or more .xml files, with the main one being gstreamer-(whatever).xml
+  - image files
+    - in .svg
+    - in .png (and maybe others)
+* We want to generate docs in HTML, PS and PDF
+* We want to use xml to to generate these
+
+CONVENTIONS
+-----------
+We stick to some simple conventions for writing docbook documentation.
+* id names:
+  - all id's start with chapter-, part-, section-, or misc-
+  - verify this is the case by looking at the generated file names in html/
+  - sections should also include the chapter name;
+    for example in a chapter called chapter-example, a section would be
+    called section-example-hello-world
+
+HOW IMAGES ARE HANDLED
+----------------------
+* the format of images used is:
+  - PNG for html
+  - EPS for ps
+  - PDF for pdf
+
+* images may need to be converted from their source format to the end format
+
+* a file called image.entities is generated that provides two entities:
+  ℑ and &IMAGE;
+  ℑ is the file extension (png, ps, pdf)
+* all generated images will be put in images/
+
+HOW THE BUILD WORKS FOR EACH FORMAT
+-----------------------------------
+* HTML:
+  - xmlto html gstreamer-whatever.xml should produce the html docs.
+  - We do this in the html subdir of the doc builddir.
+  - images are copied to (builddir)/html/images
+  - PNGS should be set to all of the png's referenced for html, both
+    already there and auto-generated
+
+* PS :
+  - images are converted to .ps files in EPS format.  Generated images are
+    put in images/
+  - xmlto ps gstreamer-whatever.xml generates the ps file
+
+* PDF :
+  There are two ways:
+  - ps2pdf is the easiest
+  - we specify ps, PS as the image type, but using xmlto the build will fail
+    because it uses ps2pdf internally and it fails to generate the images
+    By hand-generating .pdf images before xmlto we can make the build succeed.
+    (This is why image-pdf has file ext pdf but type EPS; this tricks xmlto in
+     doing the right thing)
+    xmlto pdf gstreamer-whatever.xml generates pdf (but seems to fail on the
+    FAQ, so for now we use ps2pdf)
+
+HOW THE BUILD SYSTEM IS SET UP
+------------------------------
+* make all should build html, ps, and pdf
+* html is built in a subdir, with the png/ps images copied there
+* ps and pdf are built in the current dir, in one file
+
+SPELL CHECKING
+--------------
+* with aspell
+  * aspell -b -c --mode=sgml --lang=en .xml
+    unfortunately the curses-ui of aspell (0.50.5) has problems with the xml tags
+
+
+GTK-DOC NOTES
+=============
+
+* files under revision control:
+  - Makefile.am
+  - gstreamer-sections.txt
+    describes which symbols later appear on one api-doc page
+    configure which symbols are shown/invisible/private
+  - gstreamer.types
+    the types file lists all get_type() functions that register the GObject types
+  - gstreamer-docs.sgml
+    defines the overall structure of the api documentation
+  - tmpl/
+    - only add the file to CVS if you have at least filled the short description
+      (filename corresponds to the  tag in the sections file)
+    - document as much as possible in the source (*.c files)
+
+* what to do when adding a new piece of API:
+  - add both an entity and use the entity in gstreamer-docs.sgml
+  - add a new 
 to gstreamer-sections.txt in the correct alphabetical
+    position related to the other sections (so that it is easier to locate)
+  - add all documented symbols to gstreamer-sections.txt in the proper section
+    (default),,
+  - document at least the Short_Description in tmpl/.sgml
+  - document symbols where they are defined, so that when one changes the
+    definition, the chaces are good that docs are updated.
+    - document functions, signals in the .c files
+    - document structs, typedefs, enums in the .h files
+
+* checklist:
+  - make sure *-sections.txt has a  set for each <FILE>
+  - add only *one* <TITLE> to each file, when you have multiple classes in one
+    source-file, create one <FILE> section for each class
+  - the <TITLE> *must* be named like the type of the GType, when it gets
+    registered (otherwise gtkdoc introspection fails)
+  - for clarity name the <FILE> like the <TITLE>, but all lowercase
+
+* what to do when trying to improve the docs
+  - compare the output of
+    grep "_get_type" gstreamer-sections.txt | sort
+    with the types in XXX.types to detect entries that
+    are maybe missing
+  - gtk docs does not warns about empty member docs!, run
+    find . -name "*.[c,h]" -exec egrep -Hn "^ +\* +@.*: *$" {} \;
+    in the project root to find them
+  - gtk docs does not warns about empty Returns: docs!, run
+    find . -name "*.[c,h]" -exec egrep -Hn "^ +\* +@Returns: *$" {} \;
+    in the project root to find them
+
+* what happens during a gtk-doc build ?
+  - Scan step:
+    - based on a $(MODULE).types file:
+      - gtkdoc-scangobj creates a gtkdoc-scan binary
+        - using CC, LD, CFLAGS, LDFLAGS env var
+        - using --type-init-func and --module parameters
+        - gtkdoc-scan creates
+          - $MODULE.signals.new
+          - $MODULE.hierarchy.new
+          - $MODULE.interfaces.new
+          - $MODULE.prerequisites.new
+          - $MODULE.args.new
+        - generated source and objects get deleted
+        - gtkdoc-scangobj merges changes into the original files
+    - gtkdoc-scan
+      - extracts decls of functions, macros, enums, structs, unions from headers
+      - generates
+        - $MODULE-decl.txt
+        - $MODULE-decl-list.txt
+      - $MODULE-decl-list.txt then should get copied to $MODULE-sections.txt
+    - scan-build.stamp gets created
+  
+  - Template generation step:
+    - gtkdoc-mktmpl --module=$MODULE
+      - reads in tmpl/*.sgml
+      - moves them to tmpl/*.sgml.bak
+      - recreates tmpl/*.sgml according to $MODULE-sections.txt
+      - moves unused stuff to $MODULE-unused.txt
+    - tmpl-build.stamp gets generated
+
+* Possible errors and how to fix them
+  - Warning: multiple "IDs" for constraint linkend: gst-tag-register.
+    - check if gst_tag_register is listed more than once in -sections.txt
+
+STYLE GUIDE FOR GTK-DOC
+=======================
+- this is in addition to gtk-doc's style-guide.txt
+
+- when documenting signals, use "the #Gst..." for the object receiving the
+  signal; no trailing dot, and no "that received the signal"
+- function/macro descriptions are descriptive, not imperative
+  ie, it uses the third person verb
+- synopsis and description should have most-used/application functions at the
+  top
+- functions that can return FALSE/NULL or fail should describe their failure
+  conditions like this:
+  * Returns NULL if no element with the given name is found in the bin, if
+  * the frobble was stuck in the froob, or the frizzle was frazzed.
+- a line with function attributes should be added before Returns:
+  - can contain:
+    "MT safe." - the function is verified to be multithreadingsafe
+    "Caller owns returned reference" for refcounted classes
+    "Caller owns returned value" for other types (iterators, ..)
+  - we do this because, in contrast with GLib/GTK, we are more explicit
+    about threadsafety and related issues
+- link to signals from the description like this:
+  * The <link linkend="GstBin-element-added">element-added</link> signal
+
+WEBSITE DOCUMENTATION
+=====================
+
+Updating the online documentation is pretty simple.
+Make sure that you
+a) have a working freedesktop.org account
+b) $HOME/.ssh/config set up so that it has the right User for the Host
+   (for example, I have:
+Host freedesktop.org
+  User thomasvs
+c) verify this works by doing ssh freedesktop.org and being logged in without
+   a password prompt
+d) have verified your changes build documentation locally.
+
+Then, after updating any of the docs, run "make upload" from that directory.
+Or, run "make upload" from this (docs) directory.
+
+DOCUMENTING ELEMENTS
+====================
+As of september 2005 we have some system to document plugins and elements
+in the various plugin packages.
+
+- in a submodule, docs go in docs/plugins
+- template can be copied from gst-plugins-base
+- to add plugins documentation:
+  - create docs/plugins
+  - create Makefile.am and friends, add to configure.ac
+  - create docs/version.entities.in, add to configure.ac
+  - in docs/plugins:
+    - create $(module)-plugins.types with #include <gst/gst.h>
+    - run make
+    - edit the -docs.sgml
+    - add to cvs:
+      cvs add *-plugins-docs.sgml *-plugins.args *-plugins.hierarchy *-plugins.interfaces *-plugins.prerequisites *-plugins.signals *-plugins.types inspect-build.stamp inspect.stamp scanobj-build.stamp
+      cvs add inspect
+      cvs add inspect/*.xml
+    - Additional types can be added to the documentation by placing them in
+      the .types file like this:
+        type:GstPlayBaseBin
+      This is useful for documenting plugin-private types that implement
+      signals or properties. The GType is looked up by name after all the
+      element classes have been printed - so this is only useful for types
+      that are created as a consequence of loading plugins and registering
+      the element(s).
+
+- to add a plugin to be documented:
+  - make sure inspect/ has generated a inspect/plugin-xxx.xml file for it.
+    - if it has not, make sure you have pygst installed and run 'make update'.
+      and add it to CVS.
+  - add an xi:include in -docs.sgml in the Plugins chapter for that plugin
+
+- to add an element to be documented:
+  - add an xi:include in the Elements chapter for the element
+    in the main -docs.sgml
+  - add a section for it in -sections.txt with
+      <SECTION>
+      <FILE>element-(element)</FILE>
+      <TITLE>(element)
+      GstXxx
+      
+      GstXxxClass
+      GST_XXX
+      GST_XXX_CLASS
+      GST_IS_XXX
+      GST_IS_XXX_CLASS
+      GST_TYPE_XXX
+      gst_xxx_get_type
+      

+  - add a gtk-doc section to the source code like:
+/**
+ * SECTION:element-multifdsink
+
+  and fill it with documentation about the element, preferably inside
+  a  docbook container.
+  - add an example:
+    - either a few pipelines, inside 
+    - or a piece of code:
+      - create an example program (element)-example.c in the plugin dir
+      - add the full path (starting with $(top_srcdir)) for this example
+        to the EXAMPLE_CFILES variable in Makefile.am
+      - add an xinclude of a file named "element-(element)-example.xml"
+        to the docbook documentation piece in the element source code
+  - add the header to EXTRA_HFILES in Makefile.am to be able to document
+    signals and args; in that case, the object struct needs to be in
+    -sections.txt outside of the Standard Subsection (which is annoying,
+    but ...)
+    (FIXME: are we sure we can both do the xinclude from the tmpl/ sgml,
+     as well as an override from the source itself ? maybe we should just
+     make sure the xinclude is in the source itself instead ?)
+  - if the plugin has no public header, don't add the c-file, add entries to the
+    -overrides.txt file (see playbin docs in plugins-base).
+  - to rebuild the docs, do:
+    make clean
+    make update
+    make
+  - examples will only show up using gtk-doc 1.4 or later - it relies on
+    merging stuff from .sgml with inline docs.  We might want to change
+    this to only get stuff from the source.
+  - you need to commit resulting files to git:
+    - changes to *.signals and *.args
+    - new files for your plugin created in inspect/
+  - if you get this warning:
+    " Documentation in template xxx for ./tmpl/element-yyy:Short_Description
+      being overridden by inline comments"
+    per-default the description from the GST_ELEMENT_DETAILS is put to the
+    Short_Description. This warning mean you have a different one in the section
+    docs as "@short_description:".
+
+- the plugin-doc-list on the gstreamer homepage is updated along with other
+  web site updates.
+
+- maintainer tricks:
+  - in gst-plugins-foo/docs/plugins/, run
+        make check-inspected-versions
+    to show plugins whose inspect information is not up-to-date (which is
+    usually either because they have been moved to a different module or
+    because they are not built on the maintainer's machine for some reason).
+    Whether it really makes sense to update the version number is debatable
+    (after all, the inspected information may be outdated and things may have
+    changed, in which case it would be bad to change the version number)
+  - find files that have docs
+    for file in `find . -name "*.c" -exec grep -l " * SECTION:element-" {} \; | sort`; do if [ -e ${file/.c/.h} ]; then echo ${file/.c/.h}; else echo "no header for $file"; fi; done
+    for file in `find . -name "*.cc" -exec grep -l " * SECTION:element-" {} \; | sort`; do if [ -e ${file/.cc/.h} ]; then echo ${file/.cc/.h}; else echo "no header for $file"; fi; done
+    - add those .h files to EXTRA_HFILES in Makefile.am
+  - update gst-plugins-xxx-docs.sgml
+    cd docs/plugins
+    ls -1 xml/plugin-*.xml | sort | sed -e "s/\(.*\)/    \/"
+    ls -1 xml/element-*.xml | grep -v -- "-details.xml" | sort | sed -e "s/\(.*\)/    \/"
+    - maybe we can generate these lists after "make update" and just xi:include
+      them in gst-plugins-xxx-docs.sgml. They should be committed to the vcs.
+
+- possible errors:
+  - "multiple constraints for linkend ID":
+    check if each section in -sections.txt actually starts and ends with
+    
 and 

+  - if a plugin does not show up:
+    - check inspect/plugin-xxx.xml and tmpl/elements-
+
+RANDOM THINGS I'VE LEARNED
+==========================
+
+* for clean builddir != srcdir separation, I wanted to use xmlto --searchpath
+  so the source xml could find the built entity file.
+  But xmlto --searchpath is (right now) for TeX input, not xml input.
+  xsltproc has a --path option (that xmlto doesn't use yet), but it
+  resolves single files to $(specified_path)/$(srcdir)/$(file)
+  For now, we need to hack around it by copying xml to the build dir.
+
+
+DEVHELP INTEGRATION
+-------------------
+Check https://wiki.gnome.org/Apps/Devhelp
+It's a really nice development app allowing you to look up API stuff
+from various gtk-doc'd libraries.  GStreamer is one of these ;)
+
+gtk-doc generates both html API docs and the matching .devhelp(2) books.
+
+IMAGES
+------
+It's important to keep the original source format for images, to be able
+to change and regenerate later on.  Original files go in
+docs/images

+Building GStreamer and GStreamer Applications
+3
+GStreamer Core
+
+
+
+Building GStreamer and GStreamer Applications
+
+How to build the GStreamer framework and applications using it.
+
+
+
+
+Building GStreamer on UNIX
+
+  
+  
+    On UNIX, GStreamer uses the standard GNU build system,
+    using autoconf for package
+    configuration and resolving portability issues,
+    automake for building makefiles
+    that comply with the GNU Coding Standards, and
+    libtool for building shared
+    libraries on multiple platforms.  The normal sequence for
+    compiling and installing the GStreamer library is thus:
+
+    
+      ./configure
+      make
+      make install
+    
+  
+
+  
+    The standard options provided by GNU
+    autoconf may be passed to the
+    configure script.  Please see the
+    autoconf documentation or run
+    ./configure --help for information about
+    the standard options.
+  
+
+  
+    In addition there are several options to activate or deactivate features.
+    E.g. passing  to configure
+    will turn the debugging subsystem into a non-functional stub and remove all
+    macro based invocations from within the library (and anything compiled
+    against the library afterwards.)
+  
+  
+    If library size matters and one builds in a controlled environment, it is
+    also possible to totally remove subsystem code. This is intentionally not
+    offered as a configure option as it causes an ABI break. Code built against
+    a version of GStreamer without these modifications needs to be recompiled.
+
+    
+      make CFLAGS="-DGST_REMOVE_DEPRECATED -DGST_REMOVE_DISABLED"
+    
+
+    
+      
+        
+          GST_REMOVE_DEPRECATED - Omit deprecated functions
+          from the library.
+        
+      
+      
+        
+          GST_REMOVE_DISABLED - Omit stubs for disabled
+          subsystems from the library.
+        
+      
+    
+  
+
+
+
+
+Building GStreamer Applications
+
+
+Applications and libraries can use pkg-config to get all the
+needed compiler and linker flags to build against GStreamer. Please note that
+GStreamer is split into several libraries itself.
+pkg-config --list-all | grep gstreamer will list the
+available libraries.

+
+    GStreamer Overview
+    
+GStreamer is a streaming media framework.
+It uses graphs of elements which operate on data.
+The functionality to process media is provided by plug-ins which provide
+features like elements, typefinding, and so on.
+This allows new functionality to be added simply by installing new plug-ins.
+    
+
+    
+GStreamer is cross-platform and works on most UNIX-like platforms as well as
+Windows.  It is released under the GNU Library General Public License
+(GNU LGPL).

+      including initialization, plugin management and types,
+      as well as the object hierarchy that defines elements and bins,
+      along with some more specialized elements.

Description

+
Memory is usually created by allocators with a gst_allocator_alloc()
+method call. When NULL is used as the allocator, the default allocator will
+be used.

+
New allocators can be registered with gst_allocator_register().
+Allocators are identified by name and can be retrieved with
+gst_allocator_find(). gst_allocator_set_default() can be used to change the
+default allocator.

+
New memory can be created with gst_memory_new_wrapped() that wraps the memory
+allocated elsewhere.

+

+

+
Functions

+

+
gst_allocator_find ()

+
GstAllocator *
+gst_allocator_find (const gchar *name);

+
Find a previously registered allocator with name
+. When name
+ is NULL, the
+default allocator will be returned.

+

+
Parameters

+

+++++
+
+
+
+
+
+





name
the name of the allocator. 
[allow-none]

+

+

+
Returns

+
a GstAllocator or NULL when
+the allocator with name
+was not registered. Use gst_object_unref()
+to release the allocator after usage. 

+
[transfer full][nullable]

+

+

+

+

+
gst_allocator_register ()

+
void
+gst_allocator_register (const gchar *name,
+                        GstAllocator *allocator);

+
Registers the memory allocator
+ with name
+. This function takes ownership of
+allocator
+.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+

+

+

+

+

+
gst_allocator_set_default ()

+
void
+gst_allocator_set_default (GstAllocator *allocator);

+
Set the default allocator. This function takes ownership of allocator
+.

+

+
Parameters

+

+++++
+
+
+
+
+
+





allocator
a GstAllocator. 
[transfer full]

+

+

+

+

+
gst_allocation_params_init ()

+
void
+gst_allocation_params_init (GstAllocationParams *params);

+
Initialize params
+ to its default values

+

+
Parameters

+

+++++

+

+
gst_allocation_params_copy ()

+
GstAllocationParams *
+gst_allocation_params_copy (const GstAllocationParams *params);

+
Create a copy of params
+.

+
Free-function: gst_allocation_params_free

+

+
Parameters

+

+++++
+
+
+
+
+
+





params
a GstAllocationParams. 
[transfer none][nullable]

+

+

+
Returns

+
a new #GstAllocationParams, free with
+gst_allocation_params_free(). 

+
[transfer full][nullable]

+

+

+

+

+
gst_allocation_params_free ()

+
void
+gst_allocation_params_free (GstAllocationParams *params);

+
Free params
+

+

+
Parameters

+

+++++
+
+
+
+

+
gst_allocator_alloc ()

+
GstMemory *
+gst_allocator_alloc (GstAllocator *allocator,
+                     gsize size,
+                     GstAllocationParams *params);

+
Use allocator
+ to allocate a new memory block with memory that is at least
+size
+ big.

+
The optional params
+ can specify the prefix and padding for the memory. If
+NULL is passed, no flags, no extra prefix/padding and a default alignment is
+used.

+
The prefix/padding will be filled with 0 if flags contains
+GST_MEMORY_FLAG_ZERO_PREFIXED and GST_MEMORY_FLAG_ZERO_PADDED respectively.

+
When allocator
+ is NULL, the default allocator will be used.

+
The alignment in params
+ is given as a bitmask so that align
+ + 1 equals
+the amount of bytes to align to. For example, to align to 8 bytes,
+use an alignment of 7.

+

+

Implemented Interfaces

+

+GstBin implements
+ GstChildProxy.

Includes

#include <gst/gst.h>
+

+

+

+
Description

+
GstBin is an element that can contain other GstElement, allowing them to be
+managed as a group.
+Pads from the child elements can be ghosted to the bin, see GstGhostPad.
+This makes the bin look like any other elements and enables creation of
+higher-level abstraction elements.

+
A new GstBin is created with gst_bin_new(). Use a GstPipeline instead if you
+want to create a toplevel bin because a normal bin doesn't have a bus or
+handle clock distribution of its own.

+
After the bin has been created you will typically add elements to it with
+gst_bin_add(). You can remove elements with gst_bin_remove().

+
An element can be retrieved from a bin with gst_bin_get_by_name(), using the
+elements name. gst_bin_get_by_name_recurse_up() is mainly used for internal
+purposes and will query the parent bins when the element is not found in the
+current bin.

+
An iterator of elements in a bin can be retrieved with
+gst_bin_iterate_elements(). Various other iterators exist to retrieve the
+elements in a bin.

+
gst_object_unref() is used to drop your reference to the bin.

+
The “element-added” signal is fired whenever a new element is added to
+the bin. Likewise the “element-removed” signal is fired whenever an
+element is removed from the bin.

+

+
Notes

+
A GstBin internally intercepts every GstMessage posted by its children and
+implements the following default behaviour for each of them:

+
    
+
  • GST_MESSAGE_EOS: This message is only posted by sinks in the PLAYING
+state. If all sinks posted the EOS message, this bin will post and EOS
+message upwards.
    • 
+
  • GST_MESSAGE_SEGMENT_START: Just collected and never forwarded upwards.
+The messages are used to decide when all elements have completed playback
+of their segment.
    • 
+
  • GST_MESSAGE_SEGMENT_DONE: Is posted by GstBin when all elements that posted
+a SEGMENT_START have posted a SEGMENT_DONE.
    • 
+
  • GST_MESSAGE_DURATION_CHANGED: Is posted by an element that detected a change
+in the stream duration. The default bin behaviour is to clear any
+cached duration values so that the next duration query will perform
+a full duration recalculation. The duration change is posted to the
+application so that it can refetch the new duration with a duration
+query. Note that these messages can be posted before the bin is
+prerolled, in which case the duration query might fail.
    • 
+
  • GST_MESSAGE_CLOCK_LOST: This message is posted by an element when it
+can no longer provide a clock. The default bin behaviour is to
+check if the lost clock was the one provided by the bin. If so and
+the bin is currently in the PLAYING state, the message is forwarded to
+the bin parent.
+This message is also generated when a clock provider is removed from
+the bin. If this message is received by the application, it should
+PAUSE the pipeline and set it back to PLAYING to force a new clock
+distribution.
    • 
+
  • GST_MESSAGE_CLOCK_PROVIDE: This message is generated when an element
+can provide a clock. This mostly happens when a new clock
+provider is added to the bin. The default behaviour of the bin is to
+mark the currently selected clock as dirty, which will perform a clock
+recalculation the next time the bin is asked to provide a clock.
+This message is never sent tot the application but is forwarded to
+the parent of the bin.
    • 
+
  • OTHERS: posted upwards.
    • 
+

+
A GstBin implements the following default behaviour for answering to a
+GstQuery:

+
    
+
  • GST_QUERY_DURATION:If the query has been asked before with the same format
+and the bin is a toplevel bin (ie. has no parent),
+use the cached previous value. If no previous value was cached, the
+query is sent to all sink elements in the bin and the MAXIMUM of all
+values is returned. If the bin is a toplevel bin the value is cached.
+If no sinks are available in the bin, the query fails.
    • 
+
  • GST_QUERY_POSITION:The query is sent to all sink elements in the bin and the
+MAXIMUM of all values is returned. If no sinks are available in the bin,
+the query fails.
    • 
+
  • OTHERS:the query is forwarded to all sink elements, the result
+of the first sink that answers the query successfully is returned. If no
+sink is in the bin, the query fails.
    • 
+

+
A GstBin will by default forward any event sent to it to all sink
+(GST_EVENT_TYPE_DOWNSTREAM) or source (GST_EVENT_TYPE_UPSTREAM) elements
+depending on the event type.
+If all the elements return TRUE, the bin will also return TRUE, else FALSE
+is returned. If no elements of the required type are in the bin, the event
+handler will return TRUE.

+

+

+

+
Functions

+

+
gst_bin_new ()

+
GstElement *
+gst_bin_new (const gchar *name);

+
Creates a new bin with the given name.

+

+
Parameters

+

+++++
+
+
+
+
+
+





name
the name of the new bin. 
[allow-none]

+

+

+
Returns

+
a new GstBin. 

+
[transfer floating]

+

+

+

+

+
gst_bin_add ()

+
gboolean
+gst_bin_add (GstBin *bin,
+             GstElement *element);

+
Adds the given element to the bin.  Sets the element's parent, and thus
+takes ownership of the element. An element can only be added to one bin.

+
If the element's pads are linked to other pads, the pads will be unlinked
+before the element is added to the bin.

+
When you add an element to an already-running pipeline, you will have to
+take care to set the state of the newly-added element to the desired
+state (usually PLAYING or PAUSED, same you set the pipeline to originally)
+with gst_element_set_state(), or use gst_element_sync_state_with_parent().
+The bin or pipeline will not take care of this for you.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





bin
a GstBin
 
element
the GstElement to add. 
[transfer floating]

+

+

+
Returns

+
 TRUE if the element could be added, FALSE if
+the bin does not want to accept the element.

+

+

+

+

+
gst_bin_remove ()

+
gboolean
+gst_bin_remove (GstBin *bin,
+                GstElement *element);

+
Removes the element from the bin, unparenting it as well.
+Unparenting the element means that the element will be dereferenced,
+so if the bin holds the only reference to the element, the element
+will be freed in the process of removing it from the bin.  If you
+want the element to still exist after removing, you need to call
+gst_object_ref() before removing it from the bin.

+
If the element's pads are linked to other pads, the pads will be unlinked
+before the element is removed from the bin.

+

+

+
Subclasses can override the add_element
+ and remove_element
+ to
+update the list of children in the bin.

+
The handle_message
+ method can be overridden to implement custom
+message handling.  handle_message
+ takes ownership of the message, just like
+gst_element_post_message.

+
The deep_element_added
+ vfunc will be called when a new element has been
+added to any bin inside this bin, so it will also be called if a new child
+was added to a sub-bin of this bin. GstBin implementations that override
+this message should chain up to the parent class implementation so the
+element-added-deep signal is emitted on all parents.

GST_BIN_FLAG_NO_RESYNC

+
don't resync a state change when elements are
+            added or linked in the bin (Since 1.0.5)

+		 
GST_BIN_FLAG_STREAMS_AWARE

+
Indicates whether the bin can handle elements
+            that add/remove source pads at any point in time without
+            first posting a no-more-pads signal (Since 1.10)

+		 
GST_BIN_FLAG_LAST

+
the last enum in the series of flags for bins.
+Derived classes can use this as first value in a list of flags.

+		 

+

+

+

+

+
Property Details

+

+
The “async-handling” property

+
  “async-handling”           gboolean

+
If set to TRUE, the bin will handle asynchronous state changes.
+This should be used only if the bin subclass is modifying the state
+of its children on its own.

+
Flags: Read / Write

+
Default value: FALSE

+

+

+

+
The “message-forward” property

+
  “message-forward”          gboolean

+
Forward all children messages, even those that would normally be filtered by
+the bin. This can be interesting when one wants to be notified of the EOS
+state of individual elements, for example.

+
The messages are converted to an ELEMENT message with the bin as the
+source. The structure of the message is named 'GstBinForwarded' and contains
+a field named 'message' of type GST_TYPE_MESSAGE that contains the original
+forwarded message.

+
Flags: Read / Write

+
Default value: FALSE

+

+

+

+
Signal Details

The “deep-element-added” signal

+
void
+user_function (GstBin     *bin,
+               GstBin     *sub_bin,
+               GstElement *element,
+               gpointer    user_data)

+
Will be emitted after the element was added to sub_bin.

+
The “do-latency” signal

+
gboolean
+user_function (GstBin  *bin,
+               gpointer user_data)

+
Will be emitted when the bin needs to perform latency calculations. This
+signal is only emitted for toplevel bins or when async-handling is
+enabled.

+
Only one signal handler is invoked. If no signals are connected, the
+default handler is invoked, which will query and distribute the lowest
+possible latency to all sinks.

+
Connect to this signal if the default latency calculations are not
+sufficient, like when you need different latencies for different sinks in
+the same pipeline.

Description

+
Buffers are the basic unit of data transfer in GStreamer. They contain the
+timing and offset along with other arbitrary metadata that is associated
+with the GstMemory blocks that the buffer contains.

+
Buffers are usually created with gst_buffer_new(). After a buffer has been
+created one will typically allocate memory for it and add it to the buffer.
+The following example creates a buffer that can hold a given video frame
+with a given width, height and bits per plane.

+

+  
+

GstBuffer *buffer;
+GstMemory *memory;
+gint size, width, height, bpp;
+...
+size = width * height * bpp;
+buffer = gst_buffer_new ();
+memory = gst_allocator_alloc (NULL, size, NULL);
+gst_buffer_insert_memory (buffer, -1, memory);
+...

+

+
+

+
Alternatively, use gst_buffer_new_allocate() to create a buffer with
+preallocated data of a given size.

+
Buffers can contain a list of GstMemory objects. You can retrieve how many
+memory objects with gst_buffer_n_memory() and you can get a pointer
+to memory with gst_buffer_peek_memory()

+
A buffer will usually have timestamps, and a duration, but neither of these
+are guaranteed (they may be set to GST_CLOCK_TIME_NONE). Whenever a
+meaningful value can be given for these, they should be set. The timestamps
+and duration are measured in nanoseconds (they are GstClockTime values).

+
The buffer DTS refers to the timestamp when the buffer should be decoded and
+is usually monotonically increasing. The buffer PTS refers to the timestamp when
+the buffer content should be presented to the user and is not always
+monotonically increasing.

+
A buffer can also have one or both of a start and an end offset. These are
+media-type specific. For video buffers, the start offset will generally be
+the frame number. For audio buffers, it will be the number of samples
+produced so far. For compressed data, it could be the byte offset in a
+source or destination file. Likewise, the end offset will be the offset of
+the end of the buffer. These can only be meaningfully interpreted if you
+know the media type of the buffer (the preceding CAPS event). Either or both
+can be set to GST_BUFFER_OFFSET_NONE.

+
gst_buffer_ref() is used to increase the refcount of a buffer. This must be
+done when you want to keep a handle to the buffer after pushing it to the
+next element. The buffer refcount determines the writability of the buffer, a
+buffer is only writable when the refcount is exactly 1, i.e. when the caller
+has the only reference to the buffer.

+
To efficiently create a smaller buffer out of an existing one, you can
+use gst_buffer_copy_region(). This method tries to share the memory objects
+between the two buffers.

+
If a plug-in wants to modify the buffer data or metadata in-place, it should
+first obtain a buffer that is safe to modify by using
+gst_buffer_make_writable().  This function is optimized so that a copy will
+only be made when it is necessary.

+
Several flags of the buffer can be set and unset with the
+GST_BUFFER_FLAG_SET() and GST_BUFFER_FLAG_UNSET() macros. Use
+GST_BUFFER_FLAG_IS_SET() to test if a certain GstBufferFlags flag is set.

+
Buffers can be efficiently merged into a larger buffer with
+gst_buffer_append(). Copying of memory will only be done when absolutely
+needed.

+
Arbitrary extra metadata can be set on a buffer with gst_buffer_add_meta().
+Metadata can be retrieved with gst_buffer_get_meta(). See also GstMeta

+
An element should either unref the buffer or push it out on a src pad
+using gst_pad_push() (see GstPad).

+
Buffers are usually freed by unreffing them with gst_buffer_unref(). When
+the refcount drops to 0, any memory and metadata pointed to by the buffer is
+unreffed as well. Buffers allocated from a GstBufferPool will be returned to
+the pool when the refcount drops to 0.

+
The GstParentBufferMeta is a meta which can be attached to a GstBuffer
+to hold a reference to another buffer that is only released when the child
+GstBuffer is released.

+
Typically, GstParentBufferMeta is used when the child buffer is directly
+using the GstMemory of the parent buffer, and wants to prevent the parent
+buffer from being returned to a buffer pool until the GstMemory is available
+for re-use. (Since 1.6)

+copy of the data the source buffer contains.

+

+
Parameters

+

+++++
+
+
+
+
+
+





buf

Returns

+
a new copy of buf
+.

+

+
gst_buffer_is_writable()

+
#define         gst_buffer_is_writable(buf)     gst_mini_object_is_writable (GST_MINI_OBJECT_CAST (buf))
+

+
Tests if you can safely write to a buffer's metadata or its memory array.
+It is only safe to change buffer metadata when the current reference is
+writable, i.e. nobody can see the modifications you will make.

+

+
Parameters

+

+++++
+
+
+
+
+
+





buf
a GstBuffer
 

+

+

+

+

+
gst_buffer_make_writable()

+
#define         gst_buffer_make_writable(buf)   GST_BUFFER_CAST (gst_mini_object_make_writable (GST_MINI_OBJECT_CAST (buf)))
+

+
Returns a writable copy of buf
+. If the source buffer is
+already writable, this will simply return the same buffer.

+
Use this function to ensure that a buffer can be safely modified before
+making changes to it, including changing the metadata such as PTS/DTS.

+
If the reference count of the source buffer buf
+ is exactly one, the caller
+is the sole owner and this function will return the buffer object unchanged.

+
If there is more than one reference on the object, a copy will be made using
+gst_buffer_copy(). The passed-in buf
+ will be unreffed in that case, and the
+caller will now own a reference to the new returned buffer object. Note
+that this just copies the buffer structure itself, the underlying memory is
+not copied if it can be shared amongst multiple buffers.

+
In short, this function unrefs the buf in the argument and refs the buffer
+that it returns. Don't access the argument after calling this function unless
+you have an additional reference to it.

+

+
Parameters

+

+++++
+
+
+
+
+

+
gst_buffer_replace ()

+
gboolean
+gst_buffer_replace (GstBuffer **obuf,
+                    GstBuffer *nbuf);

+
Modifies a pointer to a GstBuffer to point to a different GstBuffer. The
+modification is done atomically (so this is useful for ensuring thread safety
+in some cases), and the reference counts are updated appropriately (the old
+buffer is unreffed, the new is reffed).

+
Either nbuf
+ or the GstBuffer pointed to by obuf
+ may be NULL.

+

+

GST_BUFFER_FLAG_LIVE

+
the buffer is live data and should be discarded in
+                                the PAUSED state.

+		 
GST_BUFFER_FLAG_DECODE_ONLY

+
the buffer contains data that should be dropped
+                                because it will be clipped against the segment
+                                boundaries or because it does not contain data
+                                that should be shown to the user.

+		 
GST_BUFFER_FLAG_DISCONT

+
the buffer marks a data discontinuity in the stream.
+                                This typically occurs after a seek or a dropped buffer
+                                from a live or network source.

+		 
GST_BUFFER_FLAG_RESYNC

+
the buffer timestamps might have a discontinuity
+                                and this buffer is a good point to resynchronize.

+		 
GST_BUFFER_FLAG_CORRUPTED

+
the buffer data is corrupted.

+		 
GST_BUFFER_FLAG_MARKER

+
the buffer contains a media specific marker. for
+                                video this is typically the end of a frame boundary, for audio
+                                this is usually the start of a talkspurt.

+		 
GST_BUFFER_FLAG_HEADER

+
the buffer contains header information that is
+                                needed to decode the following data.

+		 
GST_BUFFER_FLAG_GAP

+
the buffer has been created to fill a gap in the
+                                stream and contains media neutral data (elements can
+                                switch to optimized code path that ignores the buffer
+                                content).

+		 
GST_BUFFER_FLAG_DROPPABLE

+
the buffer can be dropped without breaking the
+                                stream, for example to reduce bandwidth.

+		 
GST_BUFFER_FLAG_DELTA_UNIT

+
this unit cannot be decoded independently.

+		 
GST_BUFFER_FLAG_TAG_MEMORY

+
this flag is set when memory of the buffer
+                                is added/removed

+		 
GST_BUFFER_FLAG_SYNC_AFTER

+
Elements which write to disk or permanent
+				 storage should ensure the data is synced after
+				 writing the contents of this buffer. (Since 1.6)

+		 
GST_BUFFER_FLAG_NON_DROPPABLE

+
This buffer is important and should not be dropped.
+                                This can be used to mark important buffers, e.g. to flag
+                                RTP packets carrying keyframes or codec setup data for RTP
+                                Forward Error Correction purposes, or to prevent still video
+                                frames from being dropped by elements due to QoS. (Since 1.14)

+		 
GST_BUFFER_FLAG_LAST

+
additional media specific flags can be added starting from
+                                this flag.

struct GstParentBufferMeta

+
struct GstParentBufferMeta {

+

+
The GstParentBufferMeta is a GstMeta which can be attached to a GstBuffer
+to hold a reference to another buffer that is only released when the child
+GstBuffer is released.

+
Typically, GstParentBufferMeta is used when the child buffer is directly
+using the GstMemory of the parent buffer, and wants to prevent the parent
+buffer from being returned to a buffer pool until the GstMemory is available
+for re-use.

struct GstReferenceTimestampMeta

+
struct GstReferenceTimestampMeta {
+  GstMeta parent;
+
+  GstCaps *reference;

+

+
GstReferenceTimestampMeta can be used to attach alternative timestamps and
+possibly durations to a GstBuffer. These are generally not according to
+the pipeline clock and could be e.g. the NTP timestamp when the media was
+captured.

+
The reference is stored as a GstCaps in reference
+. Examples of valid
+references would be "timestamp/x-drivername-stream" for timestamps that are locally
+generated by some driver named "drivername" when generating the stream,
+e.g. based on a frame counter, or "timestamp/x-ntp, host=pool.ntp.org,
+port=123" for timestamps based on a specific NTP server.

Description

+
Buffer lists are an object containing a list of buffers.

+
Buffer lists are created with gst_buffer_list_new() and filled with data
+using a gst_buffer_list_insert().

+
Buffer lists can be pushed on a srcpad with gst_pad_push_list(). This is
+interesting when multiple buffers need to be pushed in one go because it
+can reduce the amount of overhead for pushing each buffer individually.

+

+

+
Functions

+

+
gst_buffer_list_new ()

+
GstBufferList *
+gst_buffer_list_new (void);

+
Creates a new, empty GstBufferList. The caller is responsible for unreffing
+the returned GstBufferList.

+
Free-function: gst_buffer_list_unref

+

+
Returns

+
the new GstBufferList. gst_buffer_list_unref()
+after usage. 

+
[transfer full]

+

+

+
gst_buffer_list_new_sized ()

+
GstBufferList *
+gst_buffer_list_new_sized (guint size);

+
Creates a new, empty GstBufferList. The caller is responsible for unreffing
+the returned GstBufferList. The list will have size
+ space preallocated so
+that memory reallocations can be avoided.

+
Description

+
A GstBufferPool is an object that can be used to pre-allocate and recycle
+buffers of the same size and with the same properties.

+
A GstBufferPool is created with gst_buffer_pool_new().

+
Once a pool is created, it needs to be configured. A call to
+gst_buffer_pool_get_config() returns the current configuration structure from
+the pool. With gst_buffer_pool_config_set_params() and
+gst_buffer_pool_config_set_allocator() the bufferpool parameters and
+allocator can be configured. Other properties can be configured in the pool
+depending on the pool implementation.

+
A bufferpool can have extra options that can be enabled with
+gst_buffer_pool_config_add_option(). The available options can be retrieved
+with gst_buffer_pool_get_options(). Some options allow for additional
+configuration properties to be set.

+
After the configuration structure has been configured,
+gst_buffer_pool_set_config() updates the configuration in the pool. This can
+fail when the configuration structure is not accepted.

+
After the a pool has been configured, it can be activated with
+gst_buffer_pool_set_active(). This will preallocate the configured resources
+in the pool.

+
When the pool is active, gst_buffer_pool_acquire_buffer() can be used to
+retrieve a buffer from the pool.

+
Buffers allocated from a bufferpool will automatically be returned to the
+pool with gst_buffer_pool_release_buffer() when their refcount drops to 0.

+
The bufferpool can be deactivated again with gst_buffer_pool_set_active().
+All further gst_buffer_pool_acquire_buffer() calls will return an error. When
+all buffers are returned to the pool they will be freed.

+
Use gst_object_unref() to release the reference to a bufferpool. If the
+refcount of the pool reaches 0, the pool will be freed.

+

+

+
Functions

+

+
GST_BUFFER_POOL_IS_FLUSHING()

+
#define GST_BUFFER_POOL_IS_FLUSHING(pool)  (g_atomic_int_get (&pool->flushing))
+

+
Check if the bufferpool is flushing. Subclasses might want to check the
+state of the pool in the acquire function.

+
Validate that changes made to config
+ are still valid in the context of the
+expected parameters. This function is a helper that can be used to validate
+changes made by a pool to a config when gst_buffer_pool_set_config()
+returns FALSE. This expects that caps
+ haven't changed and that
+min_buffers
+ aren't lower then what we initially expected.
+This does not check if options or allocator parameters are still valid,
+won't check if size have changed, since changing the size is valid to adapt
+padding.

+
A call to gst_buffer_pool_set_config() can update the allocator and params
+with the values that it is able to do. Some pools are, for example, not able

+specified in params
+. Use gst_buffer_pool_get_config() to get the currently

+

+
Description

+
The GstBus is an object responsible for delivering GstMessage packets in
+a first-in first-out way from the streaming threads (see GstTask) to the
+application.

+
Since the application typically only wants to deal with delivery of these
+messages from one thread, the GstBus will marshall the messages between
+different threads. This is important since the actual streaming of media
+is done in another thread than the application.

+
The GstBus provides support for GSource based notifications. This makes it
+possible to handle the delivery in the glib mainloop.

+
The GSource callback function gst_bus_async_signal_func() can be used to
+convert all bus messages into signal emissions.

+
A message is posted on the bus with the gst_bus_post() method. With the
+gst_bus_peek() and gst_bus_pop() methods one can look at or retrieve a
+previously posted message.

+
The bus can be polled with the gst_bus_poll() method. This methods blocks
+up to the specified timeout value until one of the specified messages types
+is posted on the bus. The application can then gst_bus_pop() the messages
+from the bus to handle them.
+Alternatively the application can register an asynchronous bus function
+using gst_bus_add_watch_full() or gst_bus_add_watch(). This function will
+install a GSource in the default glib main loop and will deliver messages
+a short while after they have been posted. Note that the main loop should
+be running for the asynchronous callbacks.

+
It is also possible to get messages from the bus without any thread
+marshalling with the gst_bus_set_sync_handler() method. This makes it
+possible to react to a message in the same thread that posted the
+message on the bus. This should only be used if the application is able
+to deal with messages from different threads.

+
Every GstPipeline has one bus.

+
Note that a GstPipeline will set its bus into flushing state when changing
+from READY to NULL state.

+

+

+
Functions

+

+
GstBusFunc ()

+
gboolean
+(*GstBusFunc) (GstBus *bus,
+               GstMessage *message,
+               gpointer user_data);

+
Specifies the type of function passed to gst_bus_add_watch() or
+gst_bus_add_watch_full(), which is called from the mainloop when a message
+is available on the bus.

+
The message passed to the function will be unreffed after execution of this
+function so it should not be freed in the function.

+
Note that this function is used as a GSourceFunc which means that returning
+FALSE will remove the GSource from the mainloop.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+





bus
the GstBus that sent the message
 
message
the GstMessage
 
user_data
user data that has been given, when registering the handler
 

+

+

+
Returns

+
 FALSE if the event source should be removed.

+

+

+

+

+
GstBusSyncHandler ()

+
GstBusSyncReply
+(*GstBusSyncHandler) (GstBus *bus,
+                      GstMessage *message,
+                      gpointer user_data);

+
Handler will be invoked synchronously, when a new message has been injected
+into the bus. This function is mostly used internally. Only one sync handler
+can be attached to a given bus.

+
If the handler returns GST_BUS_DROP, it should unref the message, else the
+message should not be unreffed by the sync handler.

+                          GDestroyNotify notify);

+
Sets the synchronous handler on the bus. The function will be called
+every time a new message is posted on the bus. Note that the function
+will be called in the same thread context as the posting object. This
+function is usually only called by the creator of the bus. Applications
+should handle messages asynchronously using the gst_bus watch and poll
+functions.

+
You cannot replace an existing sync_handler. You can pass NULL to this
+function, which will clear the existing handler.

void
+gst_bus_get_pollfd (GstBus *bus,
+                    GPollFD *fd);

+
Gets the file descriptor from the bus which can be used to get notified about
+messages being available with functions like g_poll(), and allows integration
+into other event loops based on file descriptors.
+Whenever a message is available, the POLLIN / G_IO_IN event is set.

+
Warning: NEVER read or write anything to the returned fd but only use it

+                        gpointer user_data,
+                        GDestroyNotify notify);

+
Adds a bus watch to the default main context with the given priority
+ (e.g.
+G_PRIORITY_DEFAULT). It is also possible to use a non-default  main
+context set up using g_main_context_push_thread_default() (before
+one had to create a bus watch source and attach it to the desired main
+context 'manually').

+
This function is used to receive asynchronous messages in the main loop.
+There can only be a single bus watch per bus, you must remove it before you
+can set a new one.

+
The bus watch will only work if a GLib main loop is being run.

+
When func
+ is called, the message belongs to the caller; if you want to
+keep a copy of it, call gst_message_ref() before leaving func
+.

+
The watch can be removed using gst_bus_remove_watch() or by returning FALSE
+from func
+. If the watch was added to the default main context it is also
+possible to remove the watch using g_source_remove().

+
The bus watch will take its own reference to the bus
+, so it is safe to unref
+bus
+ using gst_object_unref() after setting the bus watch.

+
gst_bus_disable_sync_message_emission ()

+
void
+gst_bus_disable_sync_message_emission (GstBus *bus);

+
Instructs GStreamer to stop emitting the "sync-message" signal for this bus.
+See gst_bus_enable_sync_message_emission() for more information.

+
In the event that multiple pieces of code have called
+gst_bus_enable_sync_message_emission(), the sync-message emissions will only
+be stopped after all calls to gst_bus_enable_sync_message_emission() were
+"cancelled" by calling this function. In this way the semantics are exactly
+the same as gst_object_ref() that which calls enable should also call
+disable.

+
MT safe.

+

+
Parameters

+

+++++
+
+
+
+
+
+





bus
a GstBus on which you previously called
+gst_bus_enable_sync_message_emission()
 

+

+

+

+

+
gst_bus_enable_sync_message_emission ()

+
void
+gst_bus_enable_sync_message_emission (GstBus *bus);

+
Instructs GStreamer to emit the "sync-message" signal after running the bus's
+sync handler. This function is here so that code can ensure that they can
+synchronously receive messages without having to affect what the bin's sync
+handler is.

+
This function may be called multiple times. To clean up, the caller is
+responsible for calling gst_bus_disable_sync_message_emission() as many times
+as this function is called.

+
While this function looks similar to gst_bus_add_signal_watch(), it is not
+exactly the same -- this function enables synchronous emission of
+signals when messages arrive; gst_bus_add_signal_watch() adds an idle callback
+to pop messages off the bus asynchronously. The sync-message signal
+comes from the thread of whatever object posted the message; the "message"
+signal is marshalled to the main thread via the main loop.

+
After calling this statement, the bus will emit the "message" signal for each

+++++
+
+
+
+
+
+
+
+

+
+





bus
a GstBus on which you want to receive the "message" signal
 
priority
The priority of the watch.

+

+

+

+
gst_bus_remove_signal_watch ()

+
void
+gst_bus_remove_signal_watch (GstBus *bus);

+
Removes a signal watch previously added with gst_bus_add_signal_watch().

+
MT safe.

+

+
Parameters

+

+++++
+
+
+
+
+
+





bus
a GstBus you previously added a signal watch to
 

+

+

+

+

+
gst_bus_poll ()

+
GstMessage *
+gst_bus_poll (GstBus *bus,
+              GstMessageType events,
+              GstClockTime timeout);

+
Poll the bus for messages. Will block while waiting for messages to come.
+You can specify a maximum time to poll with the timeout
+ parameter. If
+timeout
+ is negative, this function will block indefinitely.

+
All messages not in events
+ will be popped off the bus and will be ignored.
+It is not possible to use message enums beyond GST_MESSAGE_EXTENDED in the
+events
+ mask

+
Because poll is implemented using the "message" signal enabled by
+gst_bus_add_signal_watch(), calling gst_bus_poll() will cause the "message"
+signal to be emitted for every message that poll sees. Thus a "message"
+signal handler will see the same messages that this function sees -- neither
+will steal messages from the other.

+
This function will run a main loop from the default main context when
+polling.

+
You should never use this function, since it is pure evil. This is
+especially true for GUI applications based on Gtk+ or Qt, but also for any
+other non-trivial application that uses the GLib main loop. As this function
+runs a GLib main loop, any callback attached to the default GLib main
+context may be invoked. This could be timeouts, GUI events, I/O events etc.;
+even if gst_bus_poll() is called with a 0 timeout. Any of these callbacks
+may do things you do not expect, e.g. destroy the main application window or
+some other resource; change other application state; display a dialog and
+run another main loop until the user clicks it away. In short, using this
+function may add a lot of complexity to your code through unexpected
+re-entrancy and unexpected changes to your application's state.

+
For 0 timeouts use gst_bus_pop_filtered() instead of this function; for
+other short timeouts use gst_bus_timed_pop_filtered(); everything else is
+better handled by setting up an asynchronous bus watch and doing things
+from there.

Description

+
Caps (capabilities) are lightweight refcounted objects describing media types.
+They are composed of an array of GstStructure.

+
Caps are exposed on GstPadTemplate to describe all possible types a
+given pad can handle. They are also stored in the GstRegistry along with
+a description of the GstElement.

+
Caps are exposed on the element pads using the gst_pad_query_caps() pad
+function. This function describes the possible types that the pad can
+handle or produce at runtime.

+
A GstCaps can be constructed with the following code fragment:

+

GstCaps *caps = gst_caps_new_simple ("video/x-raw",
+   "format", G_TYPE_STRING, "I420",
+   "framerate", GST_TYPE_FRACTION, 25, 1,
+   "pixel-aspect-ratio", GST_TYPE_FRACTION, 1, 1,
+   "width", G_TYPE_INT, 320,
+   "height", G_TYPE_INT, 240,
+   NULL);

+

+
+

+
A GstCaps is fixed when it has no properties with ranges or lists. Use
+gst_caps_is_fixed() to test for fixed caps. Fixed caps can be used in a
+caps event to notify downstream elements of the current media type.

+
Various methods exist to work with the media types such as subtracting
+or intersecting.

+
Be aware that the current GstCaps / GstStructure serialization into string
+has limited support for nested GstCaps / GstStructure fields. It can only
+support one level of nesting. Using more levels will lead to unexpected
+behavior when using serialization features, such as gst_caps_to_string() or
+gst_value_serialize() and their counterparts.

+
Note that this function is the semantic equivalent of a gst_caps_ref()
+followed by a gst_caps_make_writable(). If you only want to hold on to a
+reference to the data, you should use gst_caps_ref().

+
When you are finished with the caps, call gst_caps_unref() on it.

+               GstCaps *new_caps);

+
Modifies a pointer to a GstCaps to point to a different GstCaps. This
+function is similar to gst_caps_replace() except that it takes ownership
+of new_caps
+.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





old_caps
pointer to a pointer to a GstCaps to be
+replaced. 
[inout][transfer full]
new_caps
pointer to a GstCaps that will
+replace the caps pointed to by old_caps
+. 
[transfer full][allow-none]

+

+

+
Returns

+
 TRUE if new_caps
+was different from old_caps
+

+

+

+

+

+
gst_caps_to_string ()

+
gchar *
+gst_caps_to_string (const GstCaps *caps);

+
Converts caps
+ to a string representation.  This string representation
+can be converted back to a GstCaps by gst_caps_from_string().

+
For debugging purposes its easier to do something like this:

+

+  
+    
+      
+        
+        
+      
+    
+  
1
GST_LOG ("caps are %" GST_PTR_FORMAT, caps);

+

+
+

+This prints the caps in human readable form.

+
The current implementation of serialization will lead to unexpected results
+when there are nested GstCaps / GstStructure deeper than one level.

+

+
Parameters

+

+++++
+
+
+
+
+
+





caps
a GstCaps
 

+

+

+
Returns

+
a newly allocated string representing caps
+. 

+
[transfer full]

+

+

+

+

+
gst_caps_from_string ()

+
GstCaps *
+gst_caps_from_string (const gchar *string);

+
Converts caps
+ from a string representation.

+
The current implementation of serialization will lead to unexpected results
+when there are nested GstCaps / GstStructure deeper than one level.

+

+
Parameters

+

+++++
+
+
+
+
+
+





string
a string to convert to GstCaps
 

+

+

+
Returns

+
a newly allocated GstCaps. 

+
[transfer full][nullable]

+

+

+

+

+
gst_caps_subtract ()

+
GstCaps *
+gst_caps_subtract (GstCaps *minuend,
+                   GstCaps *subtrahend);

+
Subtracts the subtrahend
+ from the minuend
+.

+
This function does not work reliably if optional properties for caps
+are included on one caps and omitted on the other.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





minuend
GstCaps to subtract from
 
subtrahend
GstCaps to subtract
 

+

+

+
Returns

+
the resulting caps. 

+
[transfer full]

+

+

+

+

+
gst_caps_make_writable()

+
#define         gst_caps_make_writable(caps)   GST_CAPS_CAST (gst_mini_object_make_writable (GST_MINI_OBJECT_CAST (caps)))
+

+
Returns a writable copy of caps
+.

+
If there is only one reference count on caps
+, the caller must be the owner,
+and so this function will return the caps object unchanged. If on the other
+hand there is more than one reference on the object, a new caps object will
+be returned. The caller's reference on caps
+ will be removed, and instead the
+caller will own a reference to the returned object.

+
In short, this function unrefs the caps in the argument and refs the caps
+that it returns. Don't access the argument after calling this function. See
+also: gst_caps_ref().

+

+
Parameters

+

+++++
+
+
+
+
+
+





caps
a GstCaps. 
[transfer full]

+

+

+
Returns

+
a writable caps which may or may not be the
+same as caps
+. 

+
[transfer full]

+

+

+

+

+
gst_caps_truncate ()

+
GstCaps *
+gst_caps_truncate (GstCaps *caps);

+
Discard all but the first structure from caps
+. Useful when
+fixating.

+
This function takes ownership of caps
+ and will call gst_caps_make_writable()
+on it if necessary, so you must not use caps
+ afterwards unless you keep an
+additional reference to it with gst_caps_ref().

+

+
Parameters

+

+++++
+
+
+
+
+
+





caps
the GstCaps to truncate. 
[transfer full]

+

+

+
Returns

+
truncated caps. 

+
[transfer full]

+

+

+

+

+
gst_caps_fixate ()

+
GstCaps *
+gst_caps_fixate (GstCaps *caps);

+
Modifies the given caps
+ into a representation with only fixed
+values. First the caps will be truncated and then the first structure will be
+fixated with gst_structure_fixate().

+
This function takes ownership of caps
+ and will call gst_caps_make_writable()
+on it so you must not use caps
+ afterwards unless you keep an additional
+reference to it with gst_caps_ref().

+

+
Parameters

+

+++++
+
+
+
+
+
+





caps
a GstCaps to fixate. 
[transfer full]

+

+

+
Returns

+
the fixated caps. 

+
[transfer full]

+

+

+

+

+
gst_caps_ref ()

+
GstCaps *
+gst_caps_ref (GstCaps *caps);

+
Add a reference to a GstCaps object.

+
From this point on, until the caller calls gst_caps_unref() or
+gst_caps_make_writable(), it is guaranteed that the caps object will not
+change. This means its structures won't change, etc. To use a GstCaps
+object, you must always have a refcount on it -- either the one made
+implicitly by e.g. gst_caps_new_simple(), or via taking one explicitly with
+this function.

+

+
Parameters

+

+++++
+
+
+
+
+
+





caps
the GstCaps to reference
 

+

+

+
Returns

+
 the same GstCaps object.

+

+

+

+

+
gst_caps_unref ()

+
void
+gst_caps_unref (GstCaps *caps);

+
Unref a GstCaps and and free all its structures and the
+structures' values when the refcount reaches 0.

+

+
Parameters

+

+++++
+
+
+
+
+
+





caps
a GstCaps.
 

+

+

enum GstCapsIntersectMode

+
Modes of caps intersection

+
GST_CAPS_INTERSECT_ZIG_ZAG
+ tries to preserve overall order of both caps
+by iterating on the caps' structures as the following matrix shows:

+

+  
+    
+      
+        
+        
+      
+    
+  
1
+2
+3
+4
+5
caps1
+      +-------------
+      | 1  2  4  7
+caps2 | 3  5  8 10
+      | 6  9 11 12

+

+
+

+Used when there is no explicit precedence of one caps over the other. e.g.
+tee's sink pad getcaps function, it will probe its src pad peers' for their
+caps and intersect them with this mode.

+
GST_CAPS_INTERSECT_FIRST
+ is useful when an element wants to preserve
+another element's caps priority order when intersecting with its own caps.
+Example: If caps1 is [A, B, C] and caps2 is [E, B, D, A], the result
+would be [A, B], maintaining the first caps priority on the intersection.

#define GST_CAPS_NONE             _gst_caps_none
+

+
The opposite of GST_CAPS_ANY: it means that the pad/element outputs an
+undefined media type that can not be detected. This macro returns a singleton
+and should not be unreffed.

+

+

+

+
GST_STATIC_CAPS_ANY

+
#define GST_STATIC_CAPS_ANY       GST_STATIC_CAPS("ANY")
+

+
Creates a new GstCaps static caps that matches anything.

+

+
GST_STATIC_CAPS_NONE

+
#define GST_STATIC_CAPS_NONE      GST_STATIC_CAPS("NONE")
+

Description

+
GstCapsFeatures can optionally be set on a GstCaps to add requirements
+for additional features for a specific GstStructure. Caps structures with
+the same name but with a non-equal set of caps features are not compatible.
+If a pad supports multiple sets of features it has to add multiple equal
+structures with different feature sets to the caps.

+
Empty GstCapsFeatures are equivalent with the GstCapsFeatures that only
+contain GST_CAPS_FEATURE_MEMORY_SYSTEM_MEMORY. ANY GstCapsFeatures as
+created by gst_caps_features_new_any() are equal to any other GstCapsFeatures
+and can be used to specify that any GstCapsFeatures would be supported, e.g.
+for elements that don't touch buffer memory. GstCaps with ANY GstCapsFeatures
+are considered non-fixed and during negotiation some GstCapsFeatures have
+to be selected.

+
Examples for caps features would be the requirement of a specific GstMemory
+types or the requirement of having a specific GstMeta on the buffer. Features
+are given as a string of the format "memory:GstMemoryTypeName" or
+"meta:GstMetaAPIName".

+

+

+
Object Hierarchy

+
    GInterface
+    ╰── GstChildProxy
+

+

+

+
Prerequisites

+

+GstChildProxy requires
+ GObject.

+

+

+
Known Implementations

+

+GstChildProxy is implemented by
+ GstBin and  GstPipeline.

+

+

+
Includes

+
#include <gst/gst.h>
+

+

+

+
Description

+
This interface abstracts handling of property sets for elements with
+children. Imagine elements such as mixers or polyphonic generators. They all
+have multiple GstPad or some kind of voice objects. Another use case are
+container elements like GstBin.
+The element implementing the interface acts as a parent for those child
+objects.

+
By implementing this interface the child properties can be accessed from the
+parent element by using gst_child_proxy_get() and gst_child_proxy_set().

+
Property names are written as "child-name::property-name". The whole naming
+scheme is recursive. Thus "child1::child2::property" is valid too, if
+"child1" and "child2" implement the GstChildProxy interface.

+

+

+
Functions

+

+
gst_child_proxy_get_children_count ()

+
guint
+gst_child_proxy_get_children_count (GstChildProxy *parent);

+
Gets the number of child objects this parent contains.

+

+
Parameters

+

+++++
+
+
+
+
+
+





parent
the parent object
 

+

+

+
Returns

+
 the number of child objects

+
MT safe.

+

+

+

+

+
gst_child_proxy_get_child_by_name ()

+
GObject *
+gst_child_proxy_get_child_by_name (GstChildProxy *parent,
+                                   const gchar *name);

+
Looks up a child element by the given name.

+
This virtual method has a default implementation that uses GstObject
+together with gst_object_get_name(). If the interface is to be used with
+GObjects, this methods needs to be overridden.

+

+
Parameters

+
the child object or NULL if
+not found (index too high). Unref after usage.

+
MT safe. 

+
[transfer full][nullable]

+

+

+

+

+
gst_child_proxy_lookup ()

 TRUE if target
+and pspec
+could be found. FALSE otherwise. In that
+case the values for pspec
+and target
+are not modified. Unref target
+after
+usage. For plain GObjects target
+is the same as object

Description

+
GStreamer uses a global clock to synchronize the plugins in a pipeline.
+Different clock implementations are possible by implementing this abstract
+base class or, more conveniently, by subclassing GstSystemClock.

+
The GstClock returns a monotonically increasing time with the method
+gst_clock_get_time(). Its accuracy and base time depend on the specific
+clock implementation but time is always expressed in nanoseconds. Since the
+baseline of the clock is undefined, the clock time returned is not
+meaningful in itself, what matters are the deltas between two clock times.
+The time returned by a clock is called the absolute time.

+
The pipeline uses the clock to calculate the running time. Usually all
+renderers synchronize to the global clock using the buffer timestamps, the
+newsegment events and the element's base time, see GstPipeline.

+
A clock implementation can support periodic and single shot clock
+notifications both synchronous and asynchronous.

+
One first needs to create a GstClockID for the periodic or single shot
+notification using gst_clock_new_single_shot_id() or
+gst_clock_new_periodic_id().

+
To perform a blocking wait for the specific time of the GstClockID use the
+gst_clock_id_wait(). To receive a callback when the specific time is reached
+in the clock use gst_clock_id_wait_async(). Both these calls can be
+interrupted with the gst_clock_id_unschedule() call. If the blocking wait is
+unscheduled a return value of GST_CLOCK_UNSCHEDULED is returned.

+
Periodic callbacks scheduled async will be repeatedly called automatically
+until it is unscheduled. To schedule a sync periodic callback,
+gst_clock_id_wait() should be called repeatedly.

+
The async callbacks can happen from any thread, either provided by the core
+or from a streaming thread. The application should be prepared for this.

+
A GstClockID that has been unscheduled cannot be used again for any wait
+operation, a new GstClockID should be created and the old unscheduled one
+should be destroyed with gst_clock_id_unref().

+
It is possible to perform a blocking wait on the same GstClockID from
+multiple threads. However, registering the same GstClockID for multiple
+async notifications is not possible, the callback will only be called for
+the thread registering the entry last.

+
None of the wait operations unref the GstClockID, the owner is responsible
+for unreffing the ids itself. This holds for both periodic and single shot
+notifications. The reason being that the owner of the GstClockID has to
+keep a handle to the GstClockID to unblock the wait on FLUSHING events or
+state changes and if the entry would be unreffed automatically, the handle
+might become invalid without any notification.

+
These clock operations do not operate on the running time, so the callbacks
+will also occur when not in PLAYING state as if the clock just keeps on
+running. Some clocks however do not progress when the element that provided
+the clock is not PLAYING.

+
When a clock has the GST_CLOCK_FLAG_CAN_SET_MASTER flag set, it can be
+slaved to another GstClock with the gst_clock_set_master(). The clock will
+then automatically be synchronized to this master clock by repeatedly
+sampling the master clock and the slave clock and recalibrating the slave
+clock with gst_clock_set_calibration(). This feature is mostly useful for
+plugins that have an internal clock but must operate with another clock
+selected by the GstPipeline.  They can track the offset and rate difference
+of their internal clock relative to the master clock by using the
+gst_clock_get_calibration() function.

+
The master/slave synchronisation can be tuned with the “timeout”,
+“window-size” and “window-threshold” properties.
+The “timeout” property defines the interval to sample the master
+clock and run the calibration functions. “window-size” defines the
+number of samples to use when calibrating and “window-threshold”
+defines the minimum number of samples before the calibration is performed.

gst_clock_set_master ()

+
gboolean
+gst_clock_set_master (GstClock *clock,
+                      GstClock *master);

+
Set master
+ as the master clock for clock
+. clock
+ will be automatically
+calibrated so that gst_clock_get_time() reports the same time as the
+master clock.

+
A clock provider that slaves its clock to a master can get the current
+calibration values with gst_clock_get_calibration().

+
master
+ can be NULL in which case clock
+ will not be slaved anymore. It will
+however keep reporting its time adjusted with the last configured rate
+and time offsets.

+

+

+
gst_clock_get_master ()

+
GstClock *
+gst_clock_get_master (GstClock *clock);

+
Set the accuracy of the clock. Some clocks have the possibility to operate
+with different accuracy at the expense of more resource usage. There is
+normally no need to change the default resolution of a clock. The resolution
+of a clock can only be changed if the clock has the
+GST_CLOCK_FLAG_CAN_SET_RESOLUTION flag set.

+
Adjusts the rate and time of clock
+. A rate of 1/1 is the normal speed of
+the clock. Values bigger than 1/1 make the clock go faster.

+
internal
+ and external
+ are calibration parameters that arrange that
+gst_clock_get_time() should have been external
+ at internal time internal
+.
+This internal time should not be in the future; that is, it should be less
+than the value of gst_clock_get_internal_time() when this function is called.

+
Subsequent calls to gst_clock_get_time() will return clock times computed as
+follows:

+

+    
+      
+        
+        
+      
+    
+

time = (internal_time - internal) * rate_num / rate_denom + external

+

+
+

+
This formula is implemented in gst_clock_adjust_unlocked(). Of course, it
+tries to do the integer arithmetic as precisely as possible.

+
Note that gst_clock_get_time() always returns increasing values so when you
+move the clock backwards, gst_clock_get_time() will report the previous value
+until the clock catches up.

+
Description

+
GstContext is a container object used to store contexts like a device
+context, a display server connection and similar concepts that should
+be shared between multiple elements.

+
Applications can set a context on a complete pipeline by using
+gst_element_set_context(), which will then be propagated to all
+child elements. Elements can handle these in GstElementClass.set_context()
+and merge them with the context information they already have.

+
When an element needs a context it will do the following actions in this
+order until one step succeeds:

+
    
+
  1. Check if the element already has a context
    2. 
+
  2. Query downstream with GST_QUERY_CONTEXT for the context
    3. 
+
  3. Query upstream with GST_QUERY_CONTEXT for the context
    4. 
+
  4. Post a GST_MESSAGE_NEED_CONTEXT message on the bus with the required
+context types and afterwards check if a usable context was set now
    5. 
+
  5. Create a context by itself and post a GST_MESSAGE_HAVE_CONTEXT message
+on the bus.
    6. 
+

+
Bins will catch GST_MESSAGE_NEED_CONTEXT messages and will set any previously
+known context on the element that asks for it if possible. Otherwise the
+application should provide one if it can.

+
GstContexts can be persistent.
+A persistent GstContext is kept in elements when they reach
+GST_STATE_NULL, non-persistent ones will be removed.
+Also, a non-persistent context won't override a previous persistent
+context set to an element.

+

+

+

Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





binding
the control binding
 
timestamp
the time the control-change should be read from
 

+

+

+                                     gpointer values);

+
Gets a number of values for the given controlled property starting at the
+requested time. The array values
+ need to hold enough space for n_values
+ of
+the same type as the objects property's type.

+
This function is useful if one wants to e.g. draw a graph of the control
+curve or apply a control curve sample by sample.

+
The values are unboxed and ready to be used. The similar function
+gst_control_binding_get_g_value_array() returns the array as GValues and is
+more suitable for bindings.

+requested time. The array values
+ need to hold enough space for n_values
+ of
+GValue.

+
This function is useful if one wants to e.g. draw a graph of the control
+curve or apply a control curve sample by sample.

+
Description

+
The GstControlSource is a base class for control value sources that could
+be used to get timestamp-value pairs. A control source essentially is a
+function over time.

+
A GstControlSource is used by first getting an instance of a specific
+control-source, creating a binding for the control-source to the target property
+of the element and then adding the binding to the element. The binding will
+convert the data types and value range to fit to the bound property.

+
For implementing a new GstControlSource one has to implement
+GstControlSourceGetValue and GstControlSourceGetValueArray functions.
+These are then used by gst_control_source_get_value() and
+gst_control_source_get_value_array() to get values for specific timestamps.

+

+

+
Functions

+

+

Description

+
GstDynamicTypeFactory is used to represent a type that can be
+automatically loaded the first time it is used. For example,
+a non-standard type for use in caps fields.

+
In general, applications and plugins don't need to use the factory
+beyond registering the type in a plugin init function. Once that is
+done, the type is stored in the registry, and ready as soon as the
+registry is loaded.

+

+
Description

+
GstElement is the abstract base class needed to construct an element that
+can be used in a GStreamer pipeline. Please refer to the plugin writers
+guide for more information on creating GstElement subclasses.

+
The name of a GstElement can be get with gst_element_get_name() and set with
+gst_element_set_name().  For speed, GST_ELEMENT_NAME() can be used in the
+core when using the appropriate locking. Do not use this in plug-ins or
+applications in order to retain ABI compatibility.

+
Elements can have pads (of the type GstPad).  These pads link to pads on
+other elements.  GstBuffer flow between these linked pads.
+A GstElement has a GList of GstPad structures for all their input (or sink)
+and output (or source) pads.
+Core and plug-in writers can add and remove pads with gst_element_add_pad()
+and gst_element_remove_pad().

+
An existing pad of an element can be retrieved by name with
+gst_element_get_static_pad(). A new dynamic pad can be created using
+gst_element_request_pad() with a GstPadTemplate.
+An iterator of all pads can be retrieved with gst_element_iterate_pads().

+
Elements can be linked through their pads.
+If the link is straightforward, use the gst_element_link()
+convenience function to link two elements, or gst_element_link_many()
+for more elements in a row.
+Use gst_element_link_filtered() to link two elements constrained by
+a specified set of GstCaps.
+For finer control, use gst_element_link_pads() and
+gst_element_link_pads_filtered() to specify the pads to link on
+each element by name.

+
Each element has a state (see GstState).  You can get and set the state
+of an element with gst_element_get_state() and gst_element_set_state().
+Setting a state triggers a GstStateChange. To get a string representation
+of a GstState, use gst_element_state_get_name().

+
You can get and set a GstClock on an element using gst_element_get_clock()
+and gst_element_set_clock().
+Some elements can provide a clock for the pipeline if
+the GST_ELEMENT_FLAG_PROVIDE_CLOCK flag is set. With the
+gst_element_provide_clock() method one can retrieve the clock provided by
+such an element.
+Not all elements require a clock to operate correctly. If the
+GST_ELEMENT_FLAG_REQUIRE_CLOCK() flag is set, a clock should be set on the
+element with gst_element_set_clock().

+
Note that clock selection and distribution is normally handled by the
+toplevel GstPipeline so the clock functions are only to be used in very
+specific situations.

+

+

+
gst_element_no_more_pads ()

+
void
+gst_element_no_more_pads (GstElement *element);

+
Use this function to signal that the element does not expect any more pads
+to show up in the current pipeline. This function should be called whenever
+pads have been added by the element itself. Elements with GST_PAD_SOMETIMES
+pad templates use this in combination with autopluggers to figure out that
+the element is done initializing its pads.

+
This function emits the “no-more-pads” signal.

+
MT safe.

+

+
Parameters

+

+++++
+
+
+
+
+
+





element

gst_element_release_request_pad ()

+
void
+gst_element_release_request_pad (GstElement *element,
+                                 GstPad *pad);

+
Makes the element free the previously requested pad as obtained
+with gst_element_request_pad().

+
This does not unref the pad. If the pad was created by using
+gst_element_request_pad(), gst_element_release_request_pad() needs to be
+followed by gst_object_unref() to free the pad
+.

+
MT safe.

+

+
Parameters

+

+++++
+
+
+
+
+
+

+
Removes pad
+ from element
+. pad
+ will be destroyed if it has not been
+referenced elsewhere using gst_object_unparent().

+
This function is used by plugin developers and should not be used
+by applications. Pads that were dynamically requested from elements
+with gst_element_request_pad() should be released with the
+gst_element_release_request_pad() function instead.

+
Pads are not automatically deactivated so elements should perform the needed
+steps to deactivate the pad in case this pad is removed in the PAUSED or
+PLAYING state. See gst_pad_set_active() for more information about
+deactivating pads.

+
The pad and the element should be unlocked when calling this function.

+
This function will emit the “pad-removed” signal on the element.

gst_element_set_start_time ()

+
void
+gst_element_set_start_time (GstElement *element,
+                            GstClockTime time);

+
Set the start time of an element. The start time of the element is the
+running time of the element when it last went to the PAUSED state. In READY
+or after a flushing seek, it is set to 0.

+
Toplevel elements like GstPipeline will manage the start_time and
+base_time on its children. Setting the start_time to GST_CLOCK_TIME_NONE
+on such a toplevel element will disable the distribution of the base_time to
+the children and can be useful if the application manages the base_time
+itself, for example if you want to synchronize capture from multiple
+pipelines, and you can also ensure that the pipelines have the same clock.

gst_element_set_state ()

+
GstStateChangeReturn
+gst_element_set_state (GstElement *element,
+                       GstState state);

+
Sets the state of the element. This function will try to set the
+requested state by going through all the intermediary states and calling
+the class's state change function for each.

+
This function can return GST_STATE_CHANGE_ASYNC, in which case the
+element will perform the remainder of the state change asynchronously in
+another thread.
+An application can use gst_element_get_state() to wait for the completion
+of the state change or it can wait for a GST_MESSAGE_ASYNC_DONE or
+GST_MESSAGE_STATE_CHANGED on the bus.

+
State changes to GST_STATE_READY or GST_STATE_NULL never return

+
+
+
+
+

+                       GstState *pending,
+                       GstClockTime timeout);

+
Gets the state of the element.

+
For elements that performed an ASYNC state change, as reported by
+gst_element_set_state(), this function will block up to the
+specified timeout value for the state change to complete.
+If the element completes the state change or goes into
+an error, this function returns immediately with a return value of
+GST_STATE_CHANGE_SUCCESS or GST_STATE_CHANGE_FAILURE respectively.

+
For elements that did not return GST_STATE_CHANGE_ASYNC, this function
+returns the current and pending state immediately.

+
This function returns GST_STATE_CHANGE_NO_PREROLL if the element
+successfully changed its state but is not able to provide data yet.
+This mostly happens for live sources that only produce data in
+GST_STATE_PLAYING. While the state change return is equivalent to
+GST_STATE_CHANGE_SUCCESS, it is returned to the application to signal that
+some sink elements might not be able to complete their state change because
+an element is not producing data to complete the preroll. When setting the
+element to playing, the preroll will complete and playback will start.

+

+

+
Returns

+
 GST_STATE_CHANGE_SUCCESS if the element has no more pending state
+and the last state change succeeded, GST_STATE_CHANGE_ASYNC if the
+element is still performing a state change or
+GST_STATE_CHANGE_FAILURE if the last state change failed.

+
gst_element_is_locked_state ()

+
gboolean
+gst_element_is_locked_state (GstElement *element);

+
Checks if the state of an element is locked.
+If the state of an element is locked, state changes of the parent don't
+affect the element.
+This way you can leave currently unused elements inside bins. Just lock their
+state before changing the state from GST_STATE_NULL.

+gst_element_continue_state (GstElement *element,
+                            GstStateChangeReturn ret);

+
Commit the state change of the element and proceed to the next
+pending state if any. This function is used
+by elements that do asynchronous state changes.
+The core will normally call this method automatically when an
+element returned GST_STATE_CHANGE_SUCCESS from the state change function.

+
If after calling this method the element still has not reached
+the pending state, the next state change is performed.

+
This method is used internally and should normally not be called by plugins
+or applications.

+
This function must be called with STATE_LOCK held.

+

+

+
gst_element_lost_state ()

+
void
+gst_element_lost_state (GstElement *element);

+
Brings the element to the lost state. The current state of the
+element is copied to the pending state so that any call to
+gst_element_get_state() will return GST_STATE_CHANGE_ASYNC.

+
An ASYNC_START message is posted. If the element was PLAYING, it will
+go to PAUSED. The element will be restored to its PLAYING state by
+the parent pipeline when it prerolls again.

+
This is mostly used for elements that lost their preroll buffer
+in the GST_STATE_PAUSED or GST_STATE_PLAYING state after a flush,
+they will go to their pending state again when a new preroll buffer is
+queued. This function can only be called when the element is currently
+not in error or an async state change.

+
This function is used internally and should normally not be called from
+plugins or applications.

element
a GstElement to invoke the convert query on.
 
src_format
a GstFormat to convert from.
 
src_val
a value to convert.
 
dest_format
the GstFormat to convert to.
 
dest_val
a pointer to the result. 
[out]

+

+
gst_element_query_position ()

+
gboolean
+gst_element_query_position (GstElement *element,
+                            GstFormat format,
+                            gint64 *cur);

+
Queries an element (usually top-level pipeline or playbin element) for the
+stream position in nanoseconds. This will be a value between 0 and the
+stream duration (if the stream duration is known). This query will usually
+only work once the pipeline is prerolled (i.e. reached PAUSED or PLAYING
+state). The application will receive an ASYNC_DONE message on the pipeline
+bus when that is the case.

+
If one repeatedly calls this function one can also create a query and reuse
+it in gst_element_query().

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+





element
a GstElement to invoke the position query on.
 
format
the GstFormat requested
 
cur
a location in which to store the current
+position, or NULL. 
[out][allow-none]

+

+

+
Returns

+
 TRUE if the query could be performed.

+

+

+

+

+
gst_element_query_duration ()

+
gboolean
+gst_element_query_duration (GstElement *element,
+                            GstFormat format,
+                            gint64 *duration);

+
Queries an element (usually top-level pipeline or playbin element) for the
+total stream duration in nanoseconds. This query will only work once the
+pipeline is prerolled (i.e. reached PAUSED or PLAYING state). The application
+will receive an ASYNC_DONE message on the pipeline bus when that is the case.

+
If the duration changes for some reason, you will get a DURATION_CHANGED
+message on the pipeline bus, in which case you should re-query the duration
+using this function.

+

+

gst_element_send_event ()

+
gboolean
+gst_element_send_event (GstElement *element,
+                        GstEvent *event);

+
Sends an event to an element. If the element doesn't implement an
+event handler, the event will be pushed on a random linked sink pad for
+downstream events or a random linked source pad for upstream events.

+
This function takes ownership of the provided event so you should
+gst_event_ref() it if you want to reuse the event after this call.

+
MT safe.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





element
a GstElement to send the event to.
 
event
the GstEvent to send to the element. 
[transfer full]

+

+

+
Returns

+
 TRUE if the event was handled. Events that trigger a preroll (such
+as flushing seeks and steps) will emit GST_MESSAGE_ASYNC_DONE.

+

+

+

+

+
gst_element_seek_simple ()

+
gboolean
+gst_element_seek_simple (GstElement *element,
+                         GstFormat format,
+                         GstSeekFlags seek_flags,
+                         gint64 seek_pos);

+
Simple API to perform a seek on the given element, meaning it just seeks
+to the given position relative to the start of the stream. For more complex
+operations like segment seeks (e.g. for looping) or changing the playback
+rate or seeking relative to the last configured playback segment you should
+use gst_element_seek().

+
In a completely prerolled PAUSED or PLAYING pipeline, seeking is always
+guaranteed to return TRUE on a seekable media type or FALSE when the media
+type is certainly not seekable (such as a live stream).

+
Some elements allow for seeking in the READY state, in this
+case they will store the seek event and execute it when they are put to
+PAUSED. If the element supports seek in READY, it will always return TRUE when
+it receives the event in the READY state.

+

+

+
+
+
+
+
+
+
+
+
+
+
+
+

+
+





element
a GstElement to seek on
 
format
a GstFormat to execute the seek in, such as GST_FORMAT_TIME
 
seek_flags
seek options; playback applications will usually want to use
+GST_SEEK_FLAG_FLUSH | GST_SEEK_FLAG_KEY_UNIT here
 
seek_pos
position to seek to (relative to the start); if you are doing
+a seek in GST_FORMAT_TIME this value is in nanoseconds -
+multiply with GST_SECOND to convert seconds to nanoseconds or
+with GST_MSECOND to convert milliseconds to nanoseconds.
 

+

+

+
Returns

+
 TRUE if the seek operation succeeded. Flushing seeks will trigger a
+preroll, which will emit GST_MESSAGE_ASYNC_DONE.

+

+

+

+

+
gst_element_seek ()

+
gboolean
+gst_element_seek (GstElement *element,

+                  GstSeekType stop_type,
+                  gint64 stop);

+
Sends a seek event to an element. See gst_event_new_seek() for the details of
+the parameters. The seek event is sent to the element using
+gst_element_send_event().

GST_STATE_CHANGE_NULL_TO_READY

+
state change from NULL to READY.

+
    
+
  • The element must check if the resources it needs are available. Device
+sinks and -sources typically try to probe the device to constrain their
+caps.
    • 
+
  • The element opens the device (in case feature need to be probed).
    • 
+

+		 
GST_STATE_CHANGE_READY_TO_PAUSED

+
state change from READY to PAUSED.

+
    
+
  • The element pads are activated in order to receive data in PAUSED.
+Streaming threads are started.
    • 
+
  • Some elements might need to return GST_STATE_CHANGE_ASYNC and complete
+the state change when they have enough information. It is a requirement
+for sinks to return GST_STATE_CHANGE_ASYNC and complete the state change
+when they receive the first buffer or GST_EVENT_EOS (preroll).
+Sinks also block the dataflow when in PAUSED.
    • 
+
  • A pipeline resets the running_time to 0.
    • 
+
  • Live sources return GST_STATE_CHANGE_NO_PREROLL and don't generate data.
    • 
+

+		 
GST_STATE_CHANGE_PAUSED_TO_PLAYING

+
state change from PAUSED to PLAYING.

+
    
+
  • Most elements ignore this state change.
    • 
+
  • The pipeline selects a GstClock and distributes this to all the children
+before setting them to PLAYING. This means that it is only allowed to
+synchronize on the GstClock in the PLAYING state.
    • 
+
  • The pipeline uses the GstClock and the running_time to calculate the
+base_time. The base_time is distributed to all children when performing
+the state change.
    • 
+
  • Sink elements stop blocking on the preroll buffer or event and start
+rendering the data.
    • 
+
  • Sinks can post GST_MESSAGE_EOS in the PLAYING state. It is not allowed
+to post GST_MESSAGE_EOS when not in the PLAYING state.
    • 
+
  • While streaming in PAUSED or PLAYING elements can create and remove
+sometimes pads.
    • 
+
  • Live sources start generating data and return GST_STATE_CHANGE_SUCCESS.
    • 
+

+		 
GST_STATE_CHANGE_PLAYING_TO_PAUSED

+
state change from PLAYING to PAUSED.

+
    
+
  • Most elements ignore this state change.
    • 
+
  • The pipeline calculates the running_time based on the last selected
+GstClock and the base_time. It stores this information to continue
+playback when going back to the PLAYING state.
    • 
+
  • Sinks unblock any GstClock wait calls.
    • 
+
  • When a sink does not have a pending buffer to play, it returns
+GST_STATE_CHANGE_ASYNC from this state change and completes the state
+change when it receives a new buffer or an GST_EVENT_EOS.
    • 
+
  • Any queued GST_MESSAGE_EOS items are removed since they will be reposted
+when going back to the PLAYING state. The EOS messages are queued in
+GstBin containers.
    • 
+
  • Live sources stop generating data and return GST_STATE_CHANGE_NO_PREROLL.
    • 
+

+		 
GST_STATE_CHANGE_PAUSED_TO_READY

+
state change from PAUSED to READY.

+
    
+
  • Sinks unblock any waits in the preroll.
    • 
+
  • Elements unblock any waits on devices
    • 
+
  • Chain or get_range functions return GST_FLOW_FLUSHING.
    • 
+
  • The element pads are deactivated so that streaming becomes impossible and
+all streaming threads are stopped.
    • 
+
  • The sink forgets all negotiated formats
    • 
+
  • Elements remove all sometimes pads
    • 
+

+		 
GST_STATE_CHANGE_READY_TO_NULL

+
state change from READY to NULL.

+
    
+
  • Elements close devices
    • 
+
  • Elements reset any internal state.
    • 
+

+		 
GST_STATE_CHANGE_NULL_TO_NULL

+
state change from NULL to NULL. (Since 1.14)

+		 
GST_STATE_CHANGE_READY_TO_READY

+
state change from READY to READY,
+This might happen when going to PAUSED asynchronously failed, in that case
+elements should make sure they are in a proper, coherent READY state. (Since 1.14)

+		 
GST_STATE_CHANGE_PAUSED_TO_PAUSED

+
state change from PAUSED to PAUSED.
+This might happen when elements were in PLAYING state and 'lost state',
+they should make sure to go back to real 'PAUSED' state (prerolling for example). (Since 1.14)

+		 
GST_STATE_CHANGE_PLAYING_TO_PLAYING

+
state change from PLAYING to PLAYING. (Since 1.14)

+		 

+

+

+

+

+
enum GstStateChangeReturn

+

+user_function (GstElement *gstelement,
+               gpointer    user_data)

+
This signals that the element will not generate more dynamic pads.
+Note that this signal will usually be emitted from the context of
+the streaming thread.

+

+

Description

+
GstElementFactory is used to create instances of elements. A
+GstElementFactory can be added to a GstPlugin as it is also a
+GstPluginFeature.

+
Use the gst_element_factory_find() and gst_element_factory_create()
+functions to create element instances or use gst_element_factory_make() as a
+convenient shortcut.

+
The following code example shows you how to create a GstFileSrc element.

Description

+
The event class provides factory methods to construct events for sending
+and functions to query (parse) received events.

+
Events are usually created with gst_event_new_*() which takes event-type
+specific parameters as arguments.
+To send an event application will usually use gst_element_send_event() and
+elements will use gst_pad_send_event() or gst_pad_push_event().
+The event should be unreffed with gst_event_unref() if it has not been sent.

+
Events that have been received can be parsed with their respective
+gst_event_parse_*() functions. It is valid to pass NULL for unwanted details.

+
Events are passed between elements in parallel to the data stream. Some events
+are serialized with buffers, others are not. Some events only travel downstream,
+others only upstream. Some events can travel both upstream and downstream.

+
The events are used to signal special conditions in the datastream such as
+EOS (end of stream) or the start of a new stream-segment.
+Events are also used to flush the pipeline of any pending data.

+
Most of the event API is used inside plugins. Applications usually only
+construct and use seek events.
+To do that gst_event_new_seek() is used to create a seek event. It takes
+the needed parameters to specify seeking time and mode.

Parameters

+

+++++
+
+
+
+

+
Parameters

+

+++++
+
+
+
+
+
+





event
The GstEvent.
 

+

+

+
Returns

+
The structure of the event. The structure
+is still owned by the event, which means that you should not free
+it and that the pointer becomes invalid when you free the event.
+This function checks if event
+is writable and will never return
+NULL.

+
MT safe. 

+
[transfer none]

+

+

+

+

+
gst_event_new_custom ()

+
GstEvent *
+gst_event_new_custom (GstEventType type,
+                      GstStructure *structure);

+
Create a new custom-typed event. This can be used for anything not
+handled by other event-specific functions to pass an event to another
+element.

+
Make sure to allocate an event type with the GST_EVENT_MAKE_TYPE macro,
+assigning a free number and filling in the correct direction and
+serialization flags.

+
New custom events can also be created by subclassing the event type if
+needed.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





type

+gst_event_get_structure (GstEvent *event);

+
Access the structure of the event.

+

+
Parameters

+

+++++
+
+
+
+
+
+





event
The GstEvent.
 

+

+

+
Returns

+
The structure of the event. The
+structure is still owned by the event, which means that you should not free
+it and that the pointer becomes invalid when you free the event.

+
MT safe. 

+
[transfer none][nullable]

+

+

+

+

+
gst_event_has_name ()

+
gboolean
+gst_event_has_name (GstEvent *event,
+                    const gchar *name);

+
Checks if event
+ has the given name
+. This function is usually used to
+check the name of a custom event.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





event
The GstEvent.
 
name
name to check
 

+

+

+
Returns

+
 TRUE if name
+matches the name of the event structure.

+

+

+

+

+
gst_event_get_seqnum ()

+
guint32
+gst_event_get_seqnum (GstEvent *event);

+
Retrieve the sequence number of a event.

+
Events have ever-incrementing sequence numbers, which may also be set
+explicitly via gst_event_set_seqnum(). Sequence numbers are typically used to
+indicate that a event corresponds to some other set of events or messages,
+for example an EOS event corresponding to a SEEK event. It is considered good
+practice to make this correspondence when possible, though it is not
+required.

+
Note that events and messages share the same sequence number incrementor;
+two events or messages will never have the same sequence number unless
+that correspondence was made explicitly.

+

+
Parameters

+

+++++
+
+
+
+
+
+





event
A GstEvent.
 

+

+

+
Returns

+
 The event's sequence number.

+
MT safe.

+

+

+

+

+
gst_event_set_seqnum ()

+
void
+gst_event_set_seqnum (GstEvent *event,
+                      guint32 seqnum);

+
Set the sequence number of a event.

+
This function might be called by the creator of a event to indicate that the
+event relates to other events or messages. See gst_event_get_seqnum() for
+more information.

+
MT safe.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





event
A GstEvent.
 
seqnum
A sequence number.
 

+

+

+

+

+
gst_event_get_running_time_offset ()

+
gint64
+gst_event_get_running_time_offset (GstEvent *event);

+
Retrieve the accumulated running time offset of the event.

+
Events passing through GstPads that have a running time
+offset set via gst_pad_set_offset() will get their offset
+adjusted according to the pad's offset.

+
If the event contains any information that related to the
+running time, this information will need to be updated
+before usage with this offset.

+

+
Parameters

+

+++++
+
+
+
+
+
+





event
A GstEvent.
 

+

+

+
Returns

+
 The event's running time offset

+
MT safe.

+

+
Since: 1.4

+

+

+

+
gst_event_set_running_time_offset ()

+
void
+gst_event_set_running_time_offset (GstEvent *event,
+                                   gint64 offset);

+
Set the running time offset of a event. See
+gst_event_get_running_time_offset() for more information.

+
MT safe.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





event
A GstEvent.
 
offset
A the new running time offset
 

+

+
Since: 1.4

+

+

+

+
gst_event_new_flush_start ()

+
GstEvent *
+gst_event_new_flush_start (void);

+
Allocate a new flush start event. The flush start event can be sent
+upstream and downstream and travels out-of-bounds with the dataflow.

+
It marks pads as being flushing and will make them return
+GST_FLOW_FLUSHING when used for data flow with gst_pad_push(),
+gst_pad_chain(), gst_pad_get_range() and gst_pad_pull_range().
+Any event (except a GST_EVENT_FLUSH_STOP) received
+on a flushing pad will return FALSE immediately.

+
Elements should unlock any blocking functions and exit their streaming
+functions as fast as possible when this event is received.

+
This event is typically generated after a seek to flush out all queued data
+in the pipeline so that the new media is played as soon as possible.

+

+
Returns

+
a new flush start event. 

+
[transfer full]

+

+

+

+

+
gst_event_new_flush_stop ()

+
GstEvent *
+gst_event_new_flush_stop (gboolean reset_time);

+
Allocate a new flush stop event. The flush stop event can be sent
+upstream and downstream and travels serialized with the dataflow.
+It is typically sent after sending a FLUSH_START event to make the
+pads accept data again.

+
Elements can process this event synchronized with the dataflow since
+the preceding FLUSH_START event stopped the dataflow.

+
This event is typically generated to complete a seek and to resume
+dataflow.

+

+
Parameters

+

+++++
+
+
+
+
+
+





reset_time
if time should be reset
 

+

+

+
Returns

+
a new flush stop event. 

+
[transfer full]

+

+

+

+

+
gst_event_parse_flush_stop ()

+
void
+gst_event_parse_flush_stop (GstEvent *event,
+                            gboolean *reset_time);

+
Parse the FLUSH_STOP event and retrieve the reset_time
+ member.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





event
The event to parse
 
reset_time
if time should be reset. 
[out]

+

+

+

+

+
gst_event_new_eos ()

+
GstEvent *
+gst_event_new_eos (void);

+
Create a new EOS event. The eos event can only travel downstream
+synchronized with the buffer flow. Elements that receive the EOS
+event on a pad can return GST_FLOW_EOS as a GstFlowReturn
+when data after the EOS event arrives.

+
The EOS event will travel down to the sink elements in the pipeline
+which will then post the GST_MESSAGE_EOS on the bus after they have
+finished playing any buffered data.

+
When all sinks have posted an EOS message, an EOS message is
+forwarded to the application.

+
The EOS event itself will not cause any state transitions of the pipeline.

+

+
Returns

+
the new EOS event. 

+
[transfer full]

+

+

+

+

+
gst_event_new_gap ()

+
GstEvent *
+gst_event_new_gap (GstClockTime timestamp,
+                   GstClockTime duration);

+
Create a new GAP event. A gap event can be thought of as conceptually
+equivalent to a buffer to signal that there is no data for a certain
+amount of time. This is useful to signal a gap to downstream elements
+which may wait for data, such as muxers or mixers or overlays, especially
+for sparse streams such as subtitle streams.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





timestamp
the start time (pts) of the gap
 
duration
the duration of the gap
 

+

+

+
Returns

+
the new GAP event.

gst_event_new_stream_start ()

+
GstEvent *
+gst_event_new_stream_start (const gchar *stream_id);

+
Create a new STREAM_START event. The stream start event can only
+travel downstream synchronized with the buffer flow. It is expected
+to be the first event that is sent for a new stream.

+
Source elements, demuxers and other elements that create new streams
+are supposed to send this event as the first event of a new stream. It
+should not be sent after a flushing seek or in similar situations
+and is used to mark the beginning of a new logical stream. Elements
+combining multiple streams must ensure that this event is only forwarded
+downstream once and not for every single input stream.

+
The stream_id
+ should be a unique string that consists of the upstream
+stream-id, / as separator and a unique stream-id for this specific
+stream. A new stream-id should only be created for a stream if the upstream
+stream is split into (potentially) multiple new streams, e.g. in a demuxer,
+but not for every single element in the pipeline.
+gst_pad_create_stream_id() or gst_pad_create_stream_id_printf() can be
+used to create a stream-id.  There are no particular semantics for the
+stream-id, though it should be deterministic (to support stream matching)
+and it might be used to order streams (besides any information conveyed by
+stream flags).

gst_event_new_segment ()

+
GstEvent *
+gst_event_new_segment (const GstSegment *segment);

+
Create a new SEGMENT event for segment
+. The segment event can only travel
+downstream synchronized with the buffer flow and contains timing information
+and playback properties for the buffers that will follow.

+
The segment event marks the range of buffers to be processed. All
+data not within the segment range is not to be processed. This can be
+used intelligently by plugins to apply more efficient methods of skipping
+unneeded data. The valid range is expressed with the start
+ and stop
+
+values.

+
The time value of the segment is used in conjunction with the start
+value to convert the buffer timestamps into the stream time. This is
+usually done in sinks to report the current stream_time.
+time
+ represents the stream_time of a buffer carrying a timestamp of
+start
+. time
+ cannot be -1.

+
start
+ cannot be -1, stop
+ can be -1. If there
+is a valid stop
+ given, it must be greater or equal the start
+, including
+when the indicated playback rate
+ is < 0.

+
The applied_rate
+ value provides information about any rate adjustment that
+has already been made to the timestamps and content on the buffers of the
+stream. (rate
+ * applied_rate
+) should always equal the rate that has been
+requested for playback. For example, if an element has an input segment
+with intended playback rate
+ of 2.0 and applied_rate of 1.0, it can adjust
+incoming timestamps and buffer content by half and output a segment event
+with rate
+ of 1.0 and applied_rate
+ of 2.0

+
After a segment event, the buffer stream time is calculated with:

+
  time + (TIMESTAMP(buf) - start) * ABS (rate * applied_rate)

gst_event_new_qos ()

GstEvent *
+gst_event_new_qos (GstQOSType type,
+                   gdouble proportion,
+                   GstClockTimeDiff diff,
+                   GstClockTime timestamp);

+
Allocate a new qos event with the given values.
+The QOS event is generated in an element that wants an upstream
+element to either reduce or increase its rate because of
+high/low CPU load or other resource usage such as network performance or
+throttling. Typically sinks generate these events for each buffer
+they receive.

+
type
+ indicates the reason for the QoS event. GST_QOS_TYPE_OVERFLOW is
+used when a buffer arrived in time or when the sink cannot keep up with
+the upstream datarate. GST_QOS_TYPE_UNDERFLOW is when the sink is not
+receiving buffers fast enough and thus has to drop late buffers.
+GST_QOS_TYPE_THROTTLE is used when the datarate is artificially limited
+by the application, for example to reduce power consumption.

+
proportion
+ indicates the real-time performance of the streaming in the
+element that generated the QoS event (usually the sink). The value is
+generally computed based on more long term statistics about the streams
+timestamps compared to the clock.
+A value < 1.0 indicates that the upstream element is producing data faster
+than real-time. A value > 1.0 indicates that the upstream element is not
+producing data fast enough. 1.0 is the ideal proportion
+ value. The
+proportion value can safely be used to lower or increase the quality of
+the element.

+
diff
+ is the difference against the clock in running time of the last
+buffer that caused the element to generate the QOS event. A negative value
+means that the buffer with timestamp
+ arrived in time. A positive value
+indicates how late the buffer with timestamp
+ was. When throttling is
+enabled, diff
+ will be set to the requested throttling interval.

+
timestamp
+ is the timestamp of the last buffer that cause the element
+to generate the QOS event. It is expressed in running time and thus an ever
+increasing value.

+
The upstream element can use the diff
+ and timestamp
+ values to decide
+whether to process more buffers. For positive diff
+, all buffers with
+timestamp <= timestamp
+ + diff
+ will certainly arrive late in the sink
+as well. A (negative) diff
+ value so that timestamp
+ + diff
+ would yield a
+result smaller than 0 is not allowed.

+
The application can use general event probes to intercept the QoS
+event and implement custom application specific QoS handling.

+                    GstSeekType stop_type,
+                    gint64 stop);

+
Allocate a new seek event with the given parameters.

+
The seek event configures playback of the pipeline between start
+ to stop
+
+at the speed given in rate
+, also called a playback segment.
+The start
+ and stop
+ values are expressed in format
+.

+
A rate
+ of 1.0 means normal playback rate, 2.0 means double speed.
+Negatives values means backwards playback. A value of 0.0 for the
+rate is not allowed and should be accomplished instead by PAUSING the
+pipeline.

+
A pipeline has a default playback segment configured with a start
+position of 0, a stop position of -1 and a rate of 1.0. The currently
+configured playback segment can be queried with GST_QUERY_SEGMENT.

+
start_type
+ and stop_type
+ specify how to adjust the currently configured
+start and stop fields in playback segment. Adjustments can be made relative
+or absolute to the last configured values. A type of GST_SEEK_TYPE_NONE
+means that the position should not be updated.

+
When the rate is positive and start
+ has been updated, playback will start
+from the newly configured start position.

+
For negative rates, playback will start from the newly configured stop
+position (if any). If the stop position is updated, it must be different from
+-1 (GST_CLOCK_TIME_NONE) for negative rates.

+
It is not possible to seek relative to the current playback position, to do
+this, PAUSE the pipeline, query the current playback position with
+GST_QUERY_POSITION and update the playback segment current position with a
+GST_SEEK_TYPE_SET to the desired position.

Create a new step event. The purpose of the step event is to instruct a sink
+to skip amount
+ (expressed in format
+) of media. It can be used to implement
+stepping through the video frame by frame or for doing fast trick modes.

+
A rate of <= 0.0 is not allowed. Pause the pipeline, for the effect of rate
+= 0.0 or first reverse the direction of playback using a seek event to get
+the same effect as rate < 0.0.

+
The flush
+ flag will clear any pending data in the pipeline before starting
+the step operation.

+
The intermediate
+ flag instructs the pipeline that this step operation is
+part of a larger step operation.

gst_event_new_protection ()

+                          const gchar *origin);

+
Creates a new event containing information specific to a particular
+protection system (uniquely identified by system_id
+), by which that
+protection system can acquire key(s) to decrypt a protected stream.

+
In order for a decryption element to decrypt media
+protected using a specific system, it first needs all the
+protection system specific information necessary to acquire the decryption
+key(s) for that stream. The functions defined here enable this information
+to be passed in events from elements that extract it
+(e.g., ISOBMFF demuxers, MPEG DASH demuxers) to protection decrypter
+elements that use it.

+
Events containing protection system specific information are created using
+gst_event_new_protection, and they can be parsed by downstream elements
+using gst_event_parse_protection.

+
In Common Encryption, protection system specific information may be located
+within ISOBMFF files, both in movie (moov) boxes and movie fragment (moof)
+boxes; it may also be contained in ContentProtection elements within MPEG
+DASH MPDs. The events created by gst_event_new_protection contain data
+identifying from which of these locations the encapsulated protection system
+specific information originated. This origin information is required as
+some protection systems use different encodings depending upon where the
+information originates.

+
The events returned by gst_event_new_protection() are implemented
+in such a way as to ensure that the most recently-pushed protection info
+event of a particular origin
+ and system_id
+ will
+be stuck to the output pad of the sending element.

+

+

Create a new STREAM_COLLECTION event. The stream collection event can only
+travel downstream synchronized with the buffer flow.

+
Source elements, demuxers and other elements that manage collections
+of streams and post GstStreamCollection messages on the bus also send
+this event downstream on each pad involved in the collection, so that
+activation of a new collection can be tracked through the downstream
+data flow.

+

+
Parameters

+

+++++

gst_event_new_stream_group_done ()

+
GstEvent *
+gst_event_new_stream_group_done (guint group_id);

+
Create a new Stream Group Done event. The stream-group-done event can
+only travel downstream synchronized with the buffer flow. Elements
+that receive the event on a pad should handle it mostly like EOS,
+and emit any data or pending buffers that would depend on more data
+arriving and unblock, since there won't be any more data.

+
This event is followed by EOS at some point in the future, and is
+generally used when switching pads - to unblock downstream so that
+new pads can be exposed before sending EOS on the existing pads.

+

+

GST_QOS_TYPE_OVERFLOW

+
The QoS event type that is produced when upstream

+

+
enum GstSeekFlags

+
Flags to be used with gst_element_seek() or gst_event_new_seek(). All flags
+can be used together.

+
A non flushing seek might take some time to perform as the currently
+playing data in the pipeline will not be cleared.

+
An accurate seek might be slower for formats that don't have any indexes
+or timestamp markers in the stream. Specifying this flag might require a
+complete scan of the file in those cases.

+
When performing a segment seek: after the playback of the segment completes,
+no EOS will be emitted by the element that performed the seek, but a
+GST_MESSAGE_SEGMENT_DONE message will be posted on the bus by the element.
+When this message is posted, it is possible to send a new seek event to
+continue playback. With this seek method it is possible to perform seamless
+looping or simple linear editing.

+
When doing fast forward (rate > 1.0) or fast reverse (rate < -1.0) trickmode
+playback, the GST_SEEK_FLAG_TRICKMODE flag can be used to instruct decoders
+and demuxers to adjust the playback rate by skipping frames. This can improve
+performance and decrease CPU usage because not all frames need to be decoded.

+
Beyond that, the GST_SEEK_FLAG_TRICKMODE_KEY_UNITS flag can be used to
+request that decoders skip all frames except key units, and
+GST_SEEK_FLAG_TRICKMODE_NO_AUDIO flags can be used to request that audio
+decoders do no decoding at all, and simple output silence.

+
The GST_SEEK_FLAG_SNAP_BEFORE flag can be used to snap to the previous
+relevant location, and the GST_SEEK_FLAG_SNAP_AFTER flag can be used to
+select the next relevant location. If GST_SEEK_FLAG_KEY_UNIT is specified,
+the relevant location is a keyframe. If both flags are specified, the nearest
+of these locations will be selected. If none are specified, the implementation is
+free to select whichever it wants.

+
The before and after here are in running time, so when playing backwards,
+the next location refers to the one that will played in next, and not the
+one that is located after in the actual source stream.

+
Also see part-seeking.txt in the GStreamer design documentation for more
+details on the meaning of these flags and the behaviour expected of
+elements that handle them.

GST_SEEK_FLAG_SEGMENT

+
perform a segment seek.

+		 
GST_SEEK_FLAG_TRICKMODE

+
when doing fast forward or fast reverse playback, allow

GST_SEEK_FLAG_SNAP_BEFORE

+
go to a location before the requested position,

go to a location after the requested position,

GST_SEEK_FLAG_SNAP_NEAREST

+
go to a position near the requested position,

+                    to the requested position, if both keyframes are at an equal
+                    distance, behaves like GST_SEEK_FLAG_SNAP_BEFORE.

+		 
GST_SEEK_FLAG_TRICKMODE_KEY_UNITS

+
when doing fast forward or fast reverse
+                    playback, request that elements only decode keyframes
+                    and skip all other content, for formats that have
+                    keyframes. (Since 1.6)

+		 
GST_SEEK_FLAG_TRICKMODE_NO_AUDIO

+
when doing fast forward or fast reverse
+                    playback, request that audio decoder elements skip

+
Description

+
GhostPads are useful when organizing pipelines with GstBin like elements.
+The idea here is to create hierarchical element graphs. The bin element
+contains a sub-graph. Now one would like to treat the bin-element like any
+other GstElement. This is where GhostPads come into play. A GhostPad acts as
+a proxy for another pad. Thus the bin can have sink and source ghost-pads
+that are associated with sink and source pads of the child elements.

+
If the target pad is known at creation time, gst_ghost_pad_new() is the
+function to use to get a ghost-pad. Otherwise one can use gst_ghost_pad_new_no_target()
+to create the ghost-pad and use gst_ghost_pad_set_target() to establish the
+association later on.

+
Note that GhostPads add overhead to the data processing of a pipeline.

+

+

+

+
Description

+
GstMemory is a lightweight refcounted object that wraps a region of memory.
+They are typically used to manage the data of a GstBuffer.

+
A GstMemory object has an allocated region of memory of maxsize. The maximum
+size does not change during the lifetime of the memory object. The memory
+also has an offset and size property that specifies the valid range of memory
+in the allocated region.

+
Memory is usually created by allocators with a gst_allocator_alloc()
+method call. When NULL is used as the allocator, the default allocator will
+be used.

+
New allocators can be registered with gst_allocator_register().
+Allocators are identified by name and can be retrieved with
+gst_allocator_find(). gst_allocator_set_default() can be used to change the
+default allocator.

+
New memory can be created with gst_memory_new_wrapped() that wraps the memory
+allocated elsewhere.

+
Refcounting of the memory block is performed with gst_memory_ref() and
+gst_memory_unref().

+
The size of the memory can be retrieved and changed with
+gst_memory_get_sizes() and gst_memory_resize() respectively.

+
Getting access to the data of the memory is performed with gst_memory_map().
+The call will return a pointer to offset bytes into the region of memory.
+After the memory access is completed, gst_memory_unmap() should be called.

+
Memory can be copied with gst_memory_copy(), which will return a writable
+copy. gst_memory_share() will create a new memory block that shares the
+memory with an existing memory block at a custom offset and with a custom
+size.

+
Memory can be efficiently merged when gst_memory_is_span() returns TRUE.

+

+

mem
a GstMemory. 
[transfer full]
info
pointer for info. 
[out]
flags
mapping flags
 

+

+

+
Returns

+
a GstMemory object mapped
+with flags
+or NULL when a mapping is not possible. 

+
[transfer full][nullable]

+

+

+

+

+
gst_memory_map ()

+
gboolean
+gst_memory_map (GstMemory *mem,
+                GstMapInfo *info,
+                GstMapFlags flags);

+
Fill info
+ with the pointer and sizes of the memory in mem
+ that can be
+accessed according to flags
+.

+
This function can return FALSE for various reasons:

+
    
+
  • the memory backed by mem
+ is not accessible with the given flags
+.
    • 
+
  • the memory was already mapped with a different mapping.
    • 
+

+
info
+ and its contents remain valid for as long as mem
+ is valid and
+until gst_memory_unmap() is called.

+
For each gst_memory_map() call, a corresponding gst_memory_unmap() call
+should be done.

+

+

+gst_memory_copy (GstMemory *mem,
+                 gssize offset,
+                 gssize size);

+
Return a copy of size
+ bytes from mem
+ starting from offset
+. This copy is
+guaranteed to be writable. size
+ can be set to -1 to return a copy
+from offset
+ to the end of the memory region.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+





mem
a GstMemory
 
offset
offset to copy from
 
size
size to copy, or -1 to copy to the end of the memory region
 

+

+

+
Returns

+
 a new GstMemory.

+

+

+

+

+
gst_memory_share ()

+
GstMemory *
+gst_memory_share (GstMemory *mem,
+                  gssize offset,
+                  gssize size);

+
Return a shared copy of size
+ bytes from mem
+ starting from offset
+. No
+memory copy is performed and the memory region is simply shared. The result
+is guaranteed to be non-writable. size
+ can be set to -1 to return a shared
+copy from offset
+ to the end of the memory region.

+

+
Parameters

+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+





mem
a GstMemory
 
offset
offset to share from
 
size
size to share, or -1 to share to the end of the memory region
 

+

+

+
Returns

+
 a new GstMemory.

+

+
gst_memory_is_span ()

+
gboolean
+gst_memory_is_span (GstMemory *mem1,
+                    GstMemory *mem2,
+                    gsize *offset);

+
Check if mem1
+ and mem2 share the memory with a common parent memory object
+and that the memory is contiguous.

+
If this is the case, the memory of mem1
+ and mem2
+ can be merged
+efficiently by performing gst_memory_share() on the parent object from
+the returned offset
+.

+
Description

+
Messages are implemented as a subclass of GstMiniObject with a generic
+GstStructure as the content. This allows for writing custom messages without
+requiring an API change while allowing a wide range of different types
+of messages.

+
Messages are posted by objects in the pipeline and are passed to the
+application using the GstBus.

+
The basic use pattern of posting a message on a GstBus is as follows:

+

+  
+    
+      
+        
+        
+      
+    
+  
1
gst_bus_post (bus, gst_message_new_eos());

+

+
+

+
A GstElement usually posts messages on the bus provided by the parent
+container using gst_element_post_message().

+

+

+
Functions

+

+
GST_MESSAGE_SRC()

+
#define GST_MESSAGE_SRC(message)        (GST_MESSAGE_CAST(message)->src)
+

+
Get the object that posted message
+.

+

+
Parameters

gst_message_get_seqnum ()

+
guint32
+gst_message_get_seqnum (GstMessage *message);

+
Retrieve the sequence number of a message.

+
Messages have ever-incrementing sequence numbers, which may also be set
+explicitly via gst_message_set_seqnum(). Sequence numbers are typically used
+to indicate that a message corresponds to some other set of messages or
+events, for example a SEGMENT_DONE message corresponding to a SEEK event. It
+is considered good practice to make this correspondence when possible, though
+it is not required.

+
Note that events and messages share the same sequence number incrementor;
+two events or messages will never have the same sequence number unless
+that correspondence was made explicitly.

+

+
Parameters

+

+++++
+
+
+
+
+
+

Set the sequence number of a message.

+
This function might be called by the creator of a message to indicate that
+the message relates to other messages or events. See gst_message_get_seqnum()
+for more information.

+

+gst_message_replace (GstMessage **old_message,
+                     GstMessage *new_message);

+
Modifies a pointer to a GstMessage to point to a different GstMessage. The
+modification is done atomically (so this is useful for ensuring thread safety
+in some cases), and the reference counts are updated appropriately (the old
+message is unreffed, the new one is reffed).

+
Either new_message
+ or the GstMessage pointed to by old_message
+ may be NULL.

gst_message_new_buffering ()

+
GstMessage *
+gst_message_new_buffering (GstObject *src,
+                           gint percent);

+
Create a new buffering message. This message can be posted by an element that
+needs to buffer data before it can continue processing. percent
+ should be a
+value between 0 and 100. A value of 100 means that the buffering completed.

+
When percent
+ is < 100 the application should PAUSE a PLAYING pipeline. When
+percent
+ is 100, the application can set the pipeline (back) to PLAYING.
+The application must be prepared to receive BUFFERING messages in the
+PREROLLING state and may only set the pipeline to PLAYING after receiving a
+message with percent
+ set to 100, which can happen after the pipeline
+completed prerolling.

This message can be posted by an element that performs synchronisation against the
+clock (live) or it could be dropped by an element that performs QoS because of QOS
+events received from a downstream element (!live).

+
running_time
+, stream_time
+, timestamp

+                          const GstStructure *entry_struct);

+
Creates a new redirect message and adds a new entry to it. Redirect messages
+are posted when an element detects that the actual data has to be retrieved
+from a different location. This is useful if such a redirection cannot be
+handled inside a source element, for example when HTTP 302/303 redirects
+return a non-HTTP URL.

+
The redirect message can hold multiple entries. The first one is added
+when the redirect message is created, with the given location, tag_list,
+entry_struct arguments. Use gst_message_add_redirect_entry() to add more
+entries.

+
Each entry has a location, a tag list, and a structure. All of these are
+optional. The tag list and structure are useful for additional metadata,
+such as bitrate statistics for the given location.

+
By default, message recipients should treat entries in the order they are
+stored. The recipient should therefore try entry #0 first, and if this
+entry is not acceptable or working, try entry #1 etc. Senders must make
+sure that they add entries in this order. However, recipients are free to
+ignore the order and pick an entry that is "best" for them. One example
+would be a recipient that scans the entries for the one with the highest
+bitrate tag.

+
The specified location string is copied. However, ownership over the tag
+list and structure are transferred to the message.

GST_MESSAGE_UNKNOWN

+
an undefined message

+		 
GST_MESSAGE_EOS

+
end-of-stream reached in a pipeline. The application will
+only receive this message in the PLAYING state and every time it sets a
+pipeline to PLAYING that is in the EOS state. The application can perform a
+flushing seek in the pipeline, which will undo the EOS state again.

+		 
GST_MESSAGE_ERROR

+
an error occurred. When the application receives an error
+message it should stop playback of the pipeline and not assume that more
+data will be played.

+		 
GST_MESSAGE_WARNING

+
a warning occurred.

+		 
GST_MESSAGE_INFO

+
an info message occurred

+		 
GST_MESSAGE_TAG

+
a tag was found.

+		 
GST_MESSAGE_BUFFERING

+
the pipeline is buffering. When the application
+receives a buffering message in the PLAYING state for a non-live pipeline it
+must PAUSE the pipeline until the buffering completes, when the percentage
+field in the message is 100%. For live pipelines, no action must be
+performed and the buffering percentage can be used to inform the user about
+the progress.

+		 
GST_MESSAGE_STATE_CHANGED

+
a state change happened

+		 
GST_MESSAGE_STATE_DIRTY

+
an element changed state in a streaming thread.
+This message is deprecated.

+		 
GST_MESSAGE_STEP_DONE

+
a stepping operation finished.

+		 
GST_MESSAGE_CLOCK_PROVIDE

+
an element notifies its capability of providing
+                            a clock. This message is used internally and
+                            never forwarded to the application.

+		 
GST_MESSAGE_CLOCK_LOST

+
The current clock as selected by the pipeline became
+                         unusable. The pipeline will select a new clock on
+                         the next PLAYING state change. The application
+                         should set the pipeline to PAUSED and back to
+                         PLAYING when this message is received.

+		 
GST_MESSAGE_NEW_CLOCK

+
a new clock was selected in the pipeline.

+		 
GST_MESSAGE_STRUCTURE_CHANGE

+
the structure of the pipeline changed. This
+message is used internally and never forwarded to the application.

+		 
GST_MESSAGE_STREAM_STATUS

+
status about a stream, emitted when it starts,
+                            stops, errors, etc..

+		 
GST_MESSAGE_APPLICATION

+
message posted by the application, possibly
+                          via an application-specific element.

+		 
GST_MESSAGE_ELEMENT

+
element-specific message, see the specific element's
+                      documentation

+		 
GST_MESSAGE_SEGMENT_START

+
pipeline started playback of a segment. This
+message is used internally and never forwarded to the application.

+		 
GST_MESSAGE_SEGMENT_DONE

+
pipeline completed playback of a segment. This
+message is forwarded to the application after all elements that posted
+GST_MESSAGE_SEGMENT_START
+ posted a GST_MESSAGE_SEGMENT_DONE message.

+		 
GST_MESSAGE_DURATION_CHANGED

+
The duration of a pipeline changed. The
+application can get the new duration with a duration query.

+		 
GST_MESSAGE_LATENCY

+
Posted by elements when their latency changes. The
+application should recalculate and distribute a new latency.

+		 
GST_MESSAGE_ASYNC_START

+
Posted by elements when they start an ASYNC
+GstStateChange. This message is not forwarded to the application but is used
+internally.

+		 
GST_MESSAGE_ASYNC_DONE

+
Posted by elements when they complete an ASYNC
+GstStateChange. The application will only receive this message from the toplevel
+pipeline.

+		 
GST_MESSAGE_REQUEST_STATE

+
Posted by elements when they want the pipeline to
+change state. This message is a suggestion to the application which can
+decide to perform the state change on (part of) the pipeline.

+		 
GST_MESSAGE_STEP_START

+
A stepping operation was started.

+		 
GST_MESSAGE_QOS

+
A buffer was dropped or an element changed its processing
+strategy for Quality of Service reasons.

+
A new table of contents (TOC) was found or previously found TOC
+was updated.

+		 
GST_MESSAGE_RESET_TIME

+
Message to request resetting the pipeline's
+    running time from the pipeline. This is an internal message which
+    applications will likely never receive.

+		 
GST_MESSAGE_STREAM_START

+
Message indicating start of a new stream. Useful
+    e.g. when using playbin in gapless playback mode, to get notified when
+    the next title actually starts playing (which will be some time after
+    the URI for the next title has been set).

+		 
GST_MESSAGE_NEED_CONTEXT

+
Message indicating that an element wants a specific context (Since 1.2)

+		 
GST_MESSAGE_HAVE_CONTEXT

+
Message indicating that an element created a context (Since 1.2)

+		 
GST_MESSAGE_EXTENDED

+
Message is an extended message type (see below).
+    These extended message IDs can't be used directly with mask-based API
+    like gst_bus_poll() or gst_bus_timed_pop_filtered(), but you can still
+    filter for GST_MESSAGE_EXTENDED and then check the result for the
+    specific type. (Since 1.4)

+		 
GST_MESSAGE_DEVICE_ADDED

+
Message indicating a GstDevice was added to
+    a GstDeviceProvider (Since 1.4)

+
Description

+
GstObject provides a root for the object hierarchy tree filed in by the
+GStreamer library.  It is currently a thin wrapper on top of
+GInitiallyUnowned. It is an abstract class that is not very usable on its own.

+
GstObject gives us basic refcounting, parenting functionality and locking.
+Most of the functions are just extended for special GStreamer needs and can be
+found under the same name in the base class of GstObject which is GObject
+(e.g. g_object_ref() becomes gst_object_ref()).

+
Since GstObject derives from GInitiallyUnowned, it also inherits the
+floating reference. Be aware that functions such as gst_bin_add() and
+gst_element_add_pad() take ownership of the floating reference.

+
In contrast to GObject instances, GstObject adds a name property. The functions
+gst_object_set_name() and gst_object_get_name() are used to set/get the name
+of the object.

+

+
controlled properties

+
Controlled properties offers a lightweight way to adjust gobject properties
+over stream-time. It works by using time-stamped value pairs that are queued
+for element-properties. At run-time the elements continuously pull value
+changes for the current stream-time.

+
What needs to be changed in a GstElement?
+Very little - it is just two steps to make a plugin controllable!

+
    
+
  • mark gobject-properties paramspecs that make sense to be controlled,
+by GST_PARAM_CONTROLLABLE.
    • 
+
  • when processing data (get, chain, loop function) at the beginning call
+gst_object_sync_values(element,timestamp).
+This will make the controller update all GObject properties that are
+under its control with the current values based on the timestamp.
    • 
+

+
What needs to be done in applications? Again it's not a lot to change.

+
    
+
  • create a GstControlSource.
+csource = gst_interpolation_control_source_new();
+g_object_set (csource, "mode", GST_INTERPOLATION_MODE_LINEAR, NULL);
    • 
+
  • Attach the GstControlSource on the controller to a property.
+gst_object_add_control_binding (object, gst_direct_control_binding_new (object, "prop1", csource));
    • 
+
  • Set the control values
+gst_timed_value_control_source_set ((GstTimedValueControlSource *)csource,0 * GST_SECOND, value1);
+gst_timed_value_control_source_set ((GstTimedValueControlSource *)csource,1 * GST_SECOND, value2);
    • 
+
  • start your pipeline
    • 
+

Functions

+

+
GST_OBJECT_FLAGS()

+
#define GST_OBJECT_FLAGS(obj)                  (GST_OBJECT_CAST (obj)->flags)
+

+
This macro returns the entire set of flags for the object.

+

+
Parameters

+

+++++
+
+
+
+
+
+





obj
a GstObject
 

+

+

+
#define GST_OBJECT_FLAG_IS_SET(obj,flag)       ((GST_OBJECT_FLAGS (obj) & (flag)) == (flag))
+

+
This macro checks to see if the given flag is set.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





obj
a GstObject
 
flag
Flag to check for
 

+

+
This macro sets the given bits.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





obj
a GstObject
 
flag
Flag to set
 

+

+

+

+

+
GST_OBJECT_FLAG_UNSET()

+
#define GST_OBJECT_FLAG_UNSET(obj,flag)        (GST_OBJECT_FLAGS (obj) &= ~(flag))

+
GST_OBJECT_NAME()

+
#define GST_OBJECT_NAME(obj)            (GST_OBJECT_CAST(obj)->name)
+

+
Get the name of this object. This is not thread-safe by default
+(i.e. you will have to make sure the object lock is taken yourself).
+If in doubt use gst_object_get_name() instead.

gst_object_ref_sink ()

+
gpointer
+gst_object_ref_sink (gpointer object);

+
Increase the reference count of object
+, and possibly remove the floating
+reference, if object
+ has a floating reference.

+
In other words, if the object is floating, then this call "assumes ownership"
+of the floating reference, converting it to a normal reference by clearing
+the floating flag while leaving the reference count unchanged. If the object
+is not floating, then this call adds a new normal reference increasing the
+reference count by one.

+
For more background on "floating references" please see the GObject
+documentation.

+                              GValue *values);

+
Gets a number of GValues for the given controlled property starting at the
+requested time. The array values
+ need to hold enough space for n_values
+ of
+GValue.

+
This function is useful if one wants to e.g. draw a graph of the control
+curve or apply a control curve sample by sample.

object
the object that has controlled properties
 
property_name
the name of the property to get
 
timestamp
the time that should be processed
 
interval
the time spacing between subsequent values
 
n_values
the number of values
 
values
array to put control-values in. 
[array length=n_values]

+

+

+
Returns

+
 TRUE if the given array could be filled, FALSE otherwise

+

+

+

+

+
gst_object_get_control_rate ()

+
GstClockTime
+gst_object_get_control_rate (GstObject *object);

+
Obtain the control-rate for this object
+. Audio processing GstElement
+objects will use this rate to sub-divide their processing loop and call
+gst_object_sync_values() inbetween. The length of the processing segment
+should be up to control
+-rate nanoseconds.

+
If the object
+ is not under property control, this will return
+GST_CLOCK_TIME_NONE. This allows the element to avoid the sub-dividing.

+
The control-rate is not expected to change if the element is in
+GST_STATE_PAUSED or GST_STATE_PLAYING.

+

+
Parameters

+

+++++
+
+
+
+
+
+





object
the object that has controlled properties
 

+

+

gst_object_set_control_rate ()

+
void
+gst_object_set_control_rate (GstObject *object,
+                             GstClockTime control_rate);

+
Change the control-rate for this object
+. Audio processing GstElement
+objects will use this rate to sub-divide their processing loop and call
+gst_object_sync_values() inbetween. The length of the processing segment
+should be up to control
+-rate nanoseconds.

+
The control-rate should not change if the element is in GST_STATE_PAUSED or
+GST_STATE_PLAYING.

+

+
Parameters

GST_OBJECT_FLAG_MAY_BE_LEAKED

+
the object is expected to stay alive even
+after gst_deinit() has been called and so should be ignored by leak
+detection tools. (Since 1.10)

+		 
GST_OBJECT_FLAG_LAST

+
subclasses can add additional flags starting from this flag

+

+
Property Details

+

+
The “name” property

+
  “name”                     gchar *

+
The name of the object.

+
Flags: Read / Write / Construct

+
Default value: NULL

+

+

+

+
The “parent” property

+
  “parent”                   GstObject *

+
The parent of the object. Please note, that when changing the 'parent'
+property, we don't emit “notify” and “deep-notify”
+signals due to locking issues. In some cases one can use
+“element-added” or “element-removed” signals on the parent to
+achieve a similar effect.

+
Flags: Read / Write

+

+

+

+
Signal Details

+

+
The “deep-notify” signal

+
void
+user_function (GstObject  *gstobject,
+               GstObject  *prop_object,
+               GParamSpec *prop,
+               gpointer    user_data)

+
The deep notify signal is used to be notified of property changes. It is
+typically attached to the toplevel bin to receive notifications from all
+the elements contained in that bin.

+

+

+





gstobject
a GstObject
 
prop_object
the object that originated the signal
 
prop
the property that changed
 
user_data
user data set when the signal handler was connected.
 

+

+
Flags: No Hooks

+
Description

+
A GstElement is linked to other elements via "pads", which are extremely
+light-weight generic link points.

+
Pads have a GstPadDirection, source pads produce data, sink pads consume
+data.

+
Pads are typically created from a GstPadTemplate with
+gst_pad_new_from_template() and are then added to a GstElement. This usually
+happens when the element is created but it can also happen dynamically based
+on the data that the element is processing or based on the pads that the
+application requests.

+
Pads without pad templates can be created with gst_pad_new(),
+which takes a direction and a name as an argument.  If the name is NULL,
+then a guaranteed unique name will be assigned to it.

+
A GstElement creating a pad will typically use the various
+gst_pad_set_*_function() calls to register callbacks for events, queries or
+dataflow on the pads.

+
gst_pad_get_parent() will retrieve the GstElement that owns the pad.

+
After two pads are retrieved from an element by gst_element_get_static_pad(),
+the pads can be linked with gst_pad_link(). (For quick links,
+you can also use gst_element_link(), which will make the obvious
+link for you if it's straightforward.). Pads can be unlinked again with
+gst_pad_unlink(). gst_pad_get_peer() can be used to check what the pad is
+linked to.

+
Before dataflow is possible on the pads, they need to be activated with
+gst_pad_set_active().

+
gst_pad_query() and gst_pad_peer_query() can be used to query various
+properties of the pad and the stream.

+
To send a GstEvent on a pad, use gst_pad_send_event() and
+gst_pad_push_event(). Some events will be sticky on the pad, meaning that
+after they pass on the pad they can be queried later with
+gst_pad_get_sticky_event() and gst_pad_sticky_events_foreach().
+gst_pad_get_current_caps() and gst_pad_has_current_caps() are convenience
+functions to query the current sticky CAPS event on a pad.

+
GstElements will use gst_pad_push() and gst_pad_pull_range() to push out
+or pull in a buffer.

+
The dataflow, events and queries that happen on a pad can be monitored with
+probes that can be installed with gst_pad_add_probe(). gst_pad_is_blocked()
+can be used to check if a block probe is installed on the pad.
+gst_pad_is_blocking() checks if the blocking probe is currently blocking the
+pad. gst_pad_remove_probe() is used to remove a previously installed probe
+and unblock blocking probes if any.

+
Pad have an offset that can be retrieved with gst_pad_get_offset(). This
+offset will be applied to the running_time of all data passing over the pad.
+gst_pad_set_offset() can be used to change the offset.

+
Convenience functions exist to start, pause and stop the task on a pad with
+gst_pad_start_task(), gst_pad_pause_task() and gst_pad_stop_task()
+respectively.

+                   guint size,
+                   GstBuffer **buffer);

+
When pad
+ is flushing this function returns GST_FLOW_FLUSHING
+immediately and buffer
+ is NULL.

+
Calls the getrange function of pad
+, see GstPadGetRangeFunction for a
+description of a getrange function. If pad
+ has no getrange function
+installed (see gst_pad_set_getrange_function()) this function returns
+GST_FLOW_NOT_SUPPORTED.

+
If buffer
+ points to a variable holding NULL, a valid new GstBuffer will be
+placed in buffer
+ when this function returns GST_FLOW_OK. The new buffer
+must be freed with gst_buffer_unref() after usage.

+
When buffer
+ points to a variable that points to a valid GstBuffer, the
+buffer will be filled with the result data when this function returns
+GST_FLOW_OK. If the provided buffer is larger than size
+, only
+size
+ bytes will be filled in the result buffer and its size will be updated
+accordingly.

+
Note that less than size
+ bytes can be returned in buffer
+ when, for example,
+an EOS condition is near or when buffer
+ is not large enough to hold size
+
+bytes. The caller should check the result buffer size to get the result size.

+
When this function returns any other result value than GST_FLOW_OK, buffer
+
+will be unchanged.

+
This is a lowlevel function. Usually gst_pad_pull_range() is used.

+GST_QUERY_SEEKING.

+
Any offset
+ larger or equal than the length will make the function return
+GST_FLOW_EOS, which corresponds to EOS. In this case buffer
+ does not
+contain a valid buffer.

+
The buffer size of buffer
+ will only be smaller than length
+ when offset
+ is
+near the end of the stream. In all other cases, the size of buffer
+ must be
+exactly the requested size.

+
It is allowed to call this function with a 0 length
+ and valid offset
+, in
+which case buffer
+ will contain a 0-sized buffer and the function returns
+GST_FLOW_OK.

+
When this function is called with a -1 offset
+, the sequentially next buffer
+of length length
+ in the stream is returned.

+
When this function is called with a -1 length
+, a buffer with a default
+optimal length is returned in buffer
+. The length might depend on the value
+of offset
+.

+ is not linked GST_FLOW_NOT_LINKED is returned else this
+function returns the result of gst_pad_get_range() on the peer pad.
+See gst_pad_get_range() for a list of return values and for the
+semantics of the arguments of this function.

+
If buffer
+ points to a variable holding NULL, a valid new GstBuffer will be
+placed in buffer
+ when this function returns GST_FLOW_OK. The new buffer
+must be freed with gst_buffer_unref() after usage. When this function
+returns any other result value, buffer
+ will still point to NULL.

+
When buffer
+ points to a variable that points to a valid GstBuffer, the
+buffer will be filled with the result data when this function returns
+GST_FLOW_OK. When this function returns any other result value,
+buffer
+ will be unchanged. If the provided buffer is larger than size
+, only
+size
+ bytes will be filled in the result buffer and its size will be updated
+accordingly.

+
Note that less than size
+ bytes can be returned in buffer
+ when, for example,
+an EOS condition is near or when buffer
+ is not large enough to hold size
+
+bytes. The caller should check the result buffer size to get the result size.

+GST_FLOW_ERROR if NULL. 
[out callee-allocates]

+

+

+
Returns

+
 a GstFlowReturn from the peer pad.

+
MT safe.

+

+

+

+

+
gst_pad_activate_mode ()

+
gboolean
+gst_pad_activate_mode (GstPad *pad,
+                       GstPadMode mode,
+                       gboolean active);

+
Activates or deactivates the given pad in mode
+ via dispatching to the
+pad's activatemodefunc. For use from within pad activation functions only.

+
If you don't know what this is, you probably don't want to call it.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+





pad
the GstPad to activate or deactivate.
 
mode
the requested activation mode
 
active
whether or not the pad should be active.
 

+

+

+
Returns

+
 TRUE if the operation was successful.

+
MT safe.

+

+

+

+

+
gst_pad_send_event ()

+
gboolean
+gst_pad_send_event (GstPad *pad,
+                    GstEvent *event);

+
Sends the event to the pad. This function can be used
+by applications to send events in the pipeline.

+
If pad
+ is a source pad, event
+ should be an upstream event. If pad
+ is a
+sink pad, event
+ should be a downstream event. For example, you would not
+send a GST_EVENT_EOS on a src pad; EOS events only propagate downstream.
+Furthermore, some downstream events have to be serialized with data flow,
+like EOS, while some can travel out-of-band, like GST_EVENT_FLUSH_START. If
+the event needs to be serialized with data flow, this function will take the
+pad's stream lock while calling its event function.

+
To find out whether an event type is upstream, downstream, or downstream and
+serialized, see GstEventTypeFlags, gst_event_type_get_flags(),
+GST_EVENT_IS_UPSTREAM, GST_EVENT_IS_DOWNSTREAM, and
+GST_EVENT_IS_SERIALIZED. Note that in practice that an application or
+plugin doesn't need to bother itself with this information; the core handles
+all necessary locks and checks.

+
This function takes ownership of the provided event so you should
+gst_event_ref() it if you want to reuse the event after this call.

+

+
Parameters

+
Invokes the default event handler for the given pad.

+
The EOS event will pause the task associated with pad
+ before it is forwarded
+to all internally linked pads,

The event is sent to all pads internally linked to pad
+. This function
+takes ownership of event
+.

+
Dispatches a query to a pad. The query should have been allocated by the
+caller via one of the type-specific allocation functions. The element that
+the pad belongs to is responsible for filling the query with an appropriate
+response, which should then be parsed with a type-specific query parsing
+function.

+
Again, the caller is responsible for both the allocation and deallocation of
+the query structure.

+
Please also note that some queries might need a running pipeline to work.

+

+
Parameters

+

+++++
+
+

+                          const gchar *stream_id);

+
Creates a stream-id for the source GstPad pad
+ by combining the
+upstream information with the optional stream_id
+ of the stream
+of pad
+. pad
+ must have a parent GstElement and which must have zero
+or one sinkpad. stream_id
+ can only be NULL if the parent element
+of pad
+ has only a single source pad.

+
This function generates an unique stream-id by getting the upstream
+stream-start event stream ID and appending stream_id
+ to it. If the
+element has no sinkpad it will generate an upstream stream-id by
+doing an URI query on the element and in the worst case just uses
+a random number. Source elements that don't implement the URI
+handler interface should ideally generate a unique, deterministic
+stream-id manually instead.

+
Since stream IDs are sorted alphabetically, any numbers in the
+stream ID should be printed with a fixed number of characters,
+preceded by 0's, such as by using the format %03u instead of %u.

#define GST_PAD_IS_ACCEPT_TEMPLATE(pad)    (GST_OBJECT_FLAG_IS_SET (pad, GST_PAD_FLAG_ACCEPT_TEMPLATE))
+

+
Check if the pad's accept caps operation will use the pad template caps.
+The default accept-caps will do a query caps to get the caps, which might
+be querying downstream causing unnecessary overhead. It is recommended to
+implement a proper accept-caps query handler or to use this flag to prevent
+recursive accept-caps handling.

+		 
GST_PAD_FLAG_NEED_RECONFIGURE

+
the pad should be reconfigured/renegotiated.

+		 
GST_PAD_FLAG_PENDING_EVENTS

+
the pad has pending events

+		 
GST_PAD_FLAG_FIXED_CAPS

+
the pad is using fixed caps. This means that
+    once the caps are set on the pad, the default caps query function
+    will only return those caps.

+		 
GST_PAD_FLAG_PROXY_CAPS

+
the default event and query handler will forward
+                     all events and queries to the internally linked pads
+                     instead of discarding them.

+		 
GST_PAD_FLAG_PROXY_ALLOCATION

+
the default query handler will forward

+		 
GST_PAD_FLAG_ACCEPT_INTERSECT

+
the default accept-caps handler will check
+                     it the caps intersect the query-caps result instead
+                     of checking for a subset. This is interesting for
+                     parsers that can accept incompletely specified caps.

+		 
GST_PAD_FLAG_ACCEPT_TEMPLATE

+
the default accept-caps handler will use
+                     the template pad caps instead of query caps to
+                     compare with the accept caps. Use this in combination

enum GstPadLinkCheck

+
The amount of checking to be done when linking pads. GST_PAD_LINK_CHECK_CAPS

+ are performed.

+
Only disable some of the checks if you are 100% certain you know the link
+will not fail because of hierarchy/caps compatibility failures. If uncertain,
+use the default checks (GST_PAD_LINK_CHECK_DEFAULT) or the regular methods
+for linking the pads.

+		 
GST_PAD_LINK_CHECK_TEMPLATE_CAPS

Pad is flushing.

+		 
GST_FLOW_EOS

+
Pad is EOS.

+		 
GST_FLOW_NOT_NEGOTIATED

+
Pad is not negotiated.

+		 
GST_FLOW_ERROR

+
Some (fatal) error occurred. Element generating
+                              this error should post an error message with more
+                              details.

+		 
GST_FLOW_NOT_SUPPORTED

+
This operation is not supported.

+		 
GST_FLOW_CUSTOM_ERROR

+
Elements can use values starting from

enum GstPadMode

+
The status of a GstPad. After activating a pad, which usually happens when the
+parent element goes from READY to PAUSED, the GstPadMode defines if the
+pad operates in push or pull mode.

GST_PAD_PROBE_DROP

+
drop data in data probes. For push mode this means that
+       the data item is not sent downstream. For pull mode, it means that
+       the data item is not passed upstream. In both cases, no other probes
+       are called for this item and GST_FLOW_OK or TRUE is returned to the
+       caller.

+		 
GST_PAD_PROBE_OK

+
normal probe return value. This leaves the probe in
+       place, and defers decisions about dropping or passing data to other
+       probes, if any. If there are no other probes, the default behaviour
+       for the probe type applies ('block' for blocking probes,
+       and 'pass' for non-blocking probes).

+		 
GST_PAD_PROBE_REMOVE

+
remove this probe.

+		 
GST_PAD_PROBE_PASS

+
pass the data item in the block probe and block on the
+       next item.

+		 
GST_PAD_PROBE_HANDLED

+
Data has been handled in the probe and will not be
+       forwarded further. For events and buffers this is the same behaviour as
+       GST_PAD_PROBE_DROP (except that in this case you need to unref the buffer
+       or event yourself). For queries it will also return TRUE to the caller.
+       The probe can also modify the GstFlowReturn value by using the
+       GST_PAD_PROBE_INFO_FLOW_RETURN() accessor.
+       Note that the resulting query must contain valid entries.

Description

+
Padtemplates describe the possible media types a pad or an elementfactory can
+handle. This allows for both inspection of handled types before loading the
+element plugin as well as identifying pads on elements that are not yet
+created (request or sometimes pads).

+
Pad and PadTemplates have GstCaps attached to it to describe the media type
+they are capable of dealing with. gst_pad_template_get_caps() or
+GST_PAD_TEMPLATE_CAPS() are used to get the caps of a padtemplate. It's not
+possible to modify the caps of a padtemplate after creation.

+
PadTemplates have a GstPadPresence property which identifies the lifetime
+of the pad and that can be retrieved with GST_PAD_TEMPLATE_PRESENCE(). Also
+the direction of the pad can be retrieved from the GstPadTemplate with
+GST_PAD_TEMPLATE_DIRECTION().

+
The GST_PAD_TEMPLATE_NAME_TEMPLATE() is important for GST_PAD_REQUEST pads
+because it has to be used as the name in the gst_element_get_request_pad()
+call to instantiate a pad from this template.

+
Padtemplates can be created with gst_pad_template_new() or with
+gst_static_pad_template_get(), which creates a GstPadTemplate from a
+GstStaticPadTemplate that can be filled with the
+convenient GST_STATIC_PAD_TEMPLATE() macro.

+
A padtemplate can be used to create a pad (see gst_pad_new_from_template()
+or gst_pad_new_from_static_template()) or to add to an element class
+(see gst_element_class_add_static_pad_template()).

+
The following code example shows the code to create a pad from a padtemplate.

+  GST_PAD_SINK,    // the direction of the pad
+  GST_PAD_ALWAYS,  // when this pad will be present
+  GST_STATIC_CAPS (        // the capabilities of the padtemplate
+    "audio/x-raw, "
+      "channels = (int) [ 1, 6 ]"

+element class, this is usually done in the class_init of the class:

+

+
Description

+
A GstPipeline is a special GstBin used as the toplevel container for
+the filter graph. The GstPipeline will manage the selection and
+distribution of a global GstClock as well as provide a GstBus to the
+application.

+
gst_pipeline_new() is used to create a pipeline. when you are done with
+the pipeline, use gst_object_unref() to free its resources including all
+added GstElement objects (if not otherwise referenced).

+
Elements are added and removed from the pipeline using the GstBin
+methods like gst_bin_add() and gst_bin_remove() (see GstBin).

+
Before changing the state of the GstPipeline (see GstElement) a GstBus
+can be retrieved with gst_pipeline_get_bus(). This bus can then be
+used to receive GstMessage from the elements in the pipeline.

+
By default, a GstPipeline will automatically flush the pending GstBus
+messages when going to the NULL state to ensure that no circular
+references exist when no messages are read from the GstBus. This
+behaviour can be changed with gst_pipeline_set_auto_flush_bus().

+
When the GstPipeline performs the PAUSED to PLAYING state change it will
+select a clock for the elements. The clock selection algorithm will by
+default select a clock provided by an element that is most upstream
+(closest to the source). For live pipelines (ones that return
+GST_STATE_CHANGE_NO_PREROLL from the gst_element_set_state() call) this
+will select the clock provided by the live source. For normal pipelines
+this will select a clock provided by the sinks (most likely the audio
+sink). If no element provides a clock, a default GstSystemClock is used.

+
The clock selection can be controlled with the gst_pipeline_use_clock()
+method, which will enforce a given clock on the pipeline. With
+gst_pipeline_auto_clock() the default clock selection algorithm can be
+restored.

+
A GstPipeline maintains a running time for the elements. The running
+time is defined as the difference between the current clock time and
+the base time. When the pipeline goes to READY or a flushing seek is
+performed on it, the running time is reset to 0. When the pipeline is
+set from PLAYING to PAUSED, the current clock time is sampled and used to
+configure the base time for the elements when the pipeline is set
+to PLAYING again. The effect is that the running time (as the difference
+between the clock time and the base time) will count how much time was spent
+in the PLAYING state. This default behaviour can be changed with the
+gst_element_set_start_time() method.

+

+

+

+
gst_pipeline_auto_clock ()

+
void
+gst_pipeline_auto_clock (GstPipeline *pipeline);

+
Let pipeline
+ select a clock automatically. This is the default
+behaviour.

+

+

+
Parameters

+

+++++
+
+
+
+
+
+





pipeline
a GstPipeline

gst_pipeline_set_auto_flush_bus ()

+
void
+gst_pipeline_set_auto_flush_bus (GstPipeline *pipeline,
+                                 gboolean auto_flush);

+
Usually, when a pipeline goes from READY to NULL state, it automatically
+flushes all pending messages on the bus, which is done for refcounting
+purposes, to break circular references.

+
This means that applications that update state using (async) bus messages
+(e.g. do certain things when a pipeline goes from PAUSED to READY) might
+not get to see messages when the pipeline is shut down, because they might
+be flushed before they can be dispatched in the main thread. This behaviour
+can be disabled using this function.

+
It is important that all messages on the bus are handled when the
+automatic flushing is disabled else memory leaks will be introduced.

+
MT safe.

+

+

+ will automatically flush messages when going to
+the NULL state.

+

+
Parameters

+
+
+
+
+
+

gst_pipeline_set_delay ()

+
void
+gst_pipeline_set_delay (GstPipeline *pipeline,
+                        GstClockTime delay);

+
Set the expected delay needed for all elements to perform the
+PAUSED to PLAYING state change. delay
+ will be added to the
+base time of the elements so that they wait an additional delay
+
+amount of time before starting to process buffers and cannot be
+GST_CLOCK_TIME_NONE.

+
This option is used for tuning purposes and should normally not be
+used.

+
MT safe.

void
+gst_pipeline_set_latency (GstPipeline *pipeline,
+                          GstClockTime latency);

+
Sets the latency that should be configured on the pipeline. Setting
+GST_CLOCK_TIME_NONE will restore the default behaviour of using the minimum
+latency from the LATENCY query. Setting this is usually not required and
+the pipeline will figure out an appropriate latency automatically.

+
Setting a too low latency, especially lower than the minimum latency from
+the LATENCY query, will most likely cause the pipeline to fail.

+
Description

+
GStreamer is extensible, so GstElement instances can be loaded at runtime.
+A plugin system can provide one or more of the basic

+GStreamerGstPluginFeature subclasses.
+
A plugin should export a symbol gst_plugin_desc that is a
+struct of type GstPluginDesc.
+the plugin loader will check the version of the core library the plugin was
+linked against and will create a new GstPlugin. It will then call the
+GstPluginInitFunc function that was provided in the

+gst_plugin_desc.
+
Once you have a handle to a GstPlugin (e.g. from the GstRegistry), you
+can add any object that subclasses GstPluginFeature.

+
Usually plugins are always automatically loaded so you don't need to call
+gst_plugin_load() explicitly to bring it into memory. There are options to
+statically link plugins to an app or even use GStreamer without a plugin
+repository in which case gst_plugin_load() can be needed to bring the plugin
+into memory.

+

+

+
Functions

+

+
gst_plugin_error_quark ()

+
GQuark
+gst_plugin_error_quark (void);

+
Get the error quark.

+

+
Returns

+
 The error quark used in GError messages

+

+

+

+

+
GstPluginInitFunc ()

+
gboolean
+(*GstPluginInitFunc) (GstPlugin *plugin);

+
A plugin should provide a pointer to a function of this type in the
+plugin_desc struct.
+This function will be called by the loader at startup. One would then
+register each GstPluginFeature.

+

+
Parameters

+

+++++
+
+
+
+
+
+





plugin
The plugin object
 

+

+

+
Returns

+
 TRUE if plugin initialised successfully

+

+

+

+

+
GstPluginInitFullFunc ()

+
gboolean
+(*GstPluginInitFullFunc) (GstPlugin *plugin,
+                          gpointer user_data);

+
A plugin should provide a pointer to a function of either GstPluginInitFunc
+or this type in the plugin_desc struct.
+The function will be called by the loader at startup. One would then
+register each GstPluginFeature. This version allows
+user data to be passed to init function (useful for bindings).

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





plugin
The plugin object
 
user_data
extra data
 

+

+

+
Returns

+
 TRUE if plugin initialised successfully

+

+

+

+

+
GST_PLUGIN_DEFINE()

+
#define             GST_PLUGIN_DEFINE(major,minor,name,description,init,version,license,package,origin)

+
This macro needs to be used to define the entry point and meta data of a
+plugin. One would use this macro to export a plugin, so that it can be used
+by other applications.

+
The macro uses a define named PACKAGE for the GstPluginDesc,source field.
+When using autoconf, this is usually set automatically via the AC_INIT
+macro, and set in config.h. If you are not using autoconf, you will need to
+define PACKAGE yourself and set it to a short mnemonic string identifying
+your application/package, e.g. 'someapp' or 'my-plugins-foo.

+
If defined, the GST_PACKAGE_RELEASE_DATETIME will also be used for the
+GstPluginDesc,release_datetime field.

Includes

+

+

+

+
Description

+
This interface offers methods to query and manipulate parameter preset sets.
+A preset is a bunch of property settings, together with meta data and a name.
+The name of a preset serves as key for subsequent method calls to manipulate
+single presets.
+All instances of one type will share the list of presets. The list is created
+on demand, if presets are not used, the list is not created.

+
The interface comes with a default implementation that serves most plugins.
+Wrapper plugins will override most methods to implement support for the
+native preset format of those wrapped plugins.
+One method that is useful to be overridden is gst_preset_get_property_names().
+With that one can control which properties are saved and in which order.
+When implementing support for read-only presets, one should set the vmethods
+for gst_preset_save_preset() and gst_preset_delete_preset() to NULL.
+Applications can use gst_preset_is_editable() to check for that.

+
The default implementation supports presets located in a system directory,
+application specific directory and in the users home directory. When getting
+a list of presets individual presets are read and overlaid in 1) system,
+2) application and 3) user order. Whenever an earlier entry is newer, the
+later entries will be updated. Since 1.8 you can also provide extra paths
+where to find presets through the GST_PRESET_PATH environment variable.
+Presets found in those paths will be concidered as "app presets".

+

+

+

Description

+
The GstPromise object implements the container for values that may
+be available later. i.e. a Future or a Promise in

+https://en.wikipedia.org/wiki/Futures_and_promises
As with all Future/Promise-like functionality, there is the concept of the
+producer of the value and the consumer of the value.

+
A GstPromise is created with gst_promise_new() by the consumer and passed
+to the producer to avoid thread safety issues with the change callback.
+A GstPromise can be replied to with a value (or an error) by the producer
+with gst_promise_reply(). gst_promise_interrupt() is for the consumer to
+indicate to the producer that the value is not needed anymore and producing
+that value can stop.  The GST_PROMISE_RESULT_EXPIRED
+ state set by a call
+to gst_promise_expire() indicates to the consumer that a value will never
+be produced and is intended to be called by a third party that implements
+some notion of message handling such as GstBus.
+A callback can also be installed at GstPromise creation for
+result changes with gst_promise_new_with_change_func().
+The change callback can be used to chain GstPromises's together as in the
+following example.

+

+  
+

const GstStructure *reply;
+GstPromise *p;
+if (gst_promise_wait (promise) != GST_PROMISE_RESULT_REPLIED)
+  return; // interrupted or expired value
+reply = gst_promise_get_reply (promise);
+if (error in reply)
+  return; // propagate error
+p = gst_promise_new_with_change_func (another_promise_change_func, user_data, notify);
+pass p to promise-using API

+

+
+

+
Each GstPromise starts out with a GstPromiseResult of
+GST_PROMISE_RESULT_PENDING and only ever transitions once
+into one of the other GstPromiseResult's.

+
In order to support multi-threaded code, gst_promise_reply(),
+gst_promise_interrupt() and gst_promise_expire() may all be from
+different threads with some restrictions and the final result of the promise
+is whichever call is made first.  There are two restrictions on ordering:

+
    
+
  1. That gst_promise_reply() and gst_promise_interrupt() cannot be called
+after gst_promise_expire()
    2. 
+
  2. That gst_promise_reply() and gst_promise_interrupt()
+cannot be called twice.
    3. 
+

+
The change function set with gst_promise_new_with_change_func() is
+called directly from either the gst_promise_reply(),
+gst_promise_interrupt() or gst_promise_expire() and can be called
+from an arbitrary thread.  GstPromise using APIs can restrict this to
+a single thread or a subset of threads but that is entirely up to the API
+that uses GstPromise.

Description

+
Queries can be performed on pads (gst_pad_query()) and elements
+(gst_element_query()). Please note that some queries might need a running
+pipeline to work.

+
Queries can be created using the gst_query_new_*() functions.
+Query values can be set using gst_query_set_*(), and parsed using
+gst_query_parse_*() helpers.

+
The following example shows how to query the duration of a pipeline:

+res = gst_element_query (pipeline, query);
+if (res) {
+  gint64 duration;
+  gst_query_parse_duration (query, NULL, &duration);
+  g_print ("duration = %"GST_TIME_FORMAT, GST_TIME_ARGS (duration));
+} else {
+  g_print ("duration query failed...");
+}
+gst_query_unref (query);

gst_query_new_caps ()

+
GstQuery *
+gst_query_new_caps (GstCaps *filter);

+
Constructs a new query object for querying the caps.

+
The CAPS query should return the allowable caps for a pad in the context
+of the element's state, its link to other elements, and the devices or files
+it has opened. These caps must be a subset of the pad template caps. In the
+NULL state with no links, the CAPS query should ideally return the same caps
+as the pad template. In rare circumstances, an object property can affect
+the caps returned by the CAPS query, but this is discouraged.

+
For most filters, the caps returned by CAPS query is directly affected by the
+allowed caps on other pads. For demuxers and decoders, the caps returned by
+the srcpad's getcaps function is directly related to the stream data. Again,
+the CAPS query should return the most specific caps it reasonably can, since this
+helps with autoplugging.

+
The filter
+ is used to restrict the result caps, only the caps matching
+filter
+ should be returned from the CAPS query. Specifying a filter might
+greatly reduce the amount of processing an element needs to do.

+
Check if query
+ has scheduling mode set.

+
When checking if upstream supports pull mode, it is usually not
+enough to just check for GST_PAD_MODE_PULL with this function, you
+also want to check whether the scheduling flags returned by
+gst_query_parse_scheduling() have the seeking flag set (meaning
+random access is supported, not only sequential pulls).

+
Description

+
One registry holds the metadata of a set of plugins.

+
Design:

+
The GstRegistry object is a list of plugins and some functions for dealing
+with them. Each GstPlugin is matched 1-1 with a file on disk, and may or may
+not be loaded at a given time.

+
The primary source, at all times, of plugin information is each plugin file
+itself. Thus, if an application wants information about a particular plugin,
+or wants to search for a feature that satisfies given criteria, the primary
+means of doing so is to load every plugin and look at the resulting
+information that is gathered in the default registry. Clearly, this is a time
+consuming process, so we cache information in the registry file. The format
+and location of the cache file is internal to gstreamer.

+
On startup, plugins are searched for in the plugin search path. The following
+locations are checked in this order:

+
    
+
  • location from --gst-plugin-path commandline option.
    • 
+
  • the GST_PLUGIN_PATH environment variable.
    • 
+
  • the GST_PLUGIN_SYSTEM_PATH environment variable.
    • 
+
  • default locations (if GST_PLUGIN_SYSTEM_PATH is not set).
+Those default locations are:
+$XDG_DATA_HOME/gstreamer-$GST_API_VERSION/plugins/
+and $prefix/libs/gstreamer-$GST_API_VERSION/.
+$XDG_DATA_HOME defaults to
+$HOME/.local/share.
    • 
+

+
The registry cache file is loaded from
+$XDG_CACHE_HOME/gstreamer-$GST_API_VERSION/registry-$ARCH.bin
+(where $XDG_CACHE_HOME defaults to $HOME/.cache) or the file listed in the GST_REGISTRY
+env var. One reason to change the registry location is for testing.

+
For each plugin that is found in the plugin search path, there could be 3
+possibilities for cached information:

+
    
+
  • the cache may not contain information about a given file.
    • 
+
  • the cache may have stale information.
    • 
+
  • the cache may have current information.
    • 
+

+
In the first two cases, the plugin is loaded and the cache updated. In
+addition to these cases, the cache may have entries for plugins that are not
+relevant to the current process. These are marked as not available to the
+current process. If the cache is updated for whatever reason, it is marked
+dirty.

+
A dirty cache is written out at the end of initialization. Each entry is
+checked to make sure the information is minimally valid. If not, the entry is
+simply dropped.

+

+
Implementation notes:

+
The "cache" and "registry" are different concepts and can represent
+different sets of plugins. For various reasons, at init time, the cache is
+stored in the default registry, and plugins not relevant to the current
+process are marked with the GST_PLUGIN_FLAG_CACHED bit. These plugins are
+removed at the end of initialization.

+

+

+

+
Functions

+

+
gst_registry_get ()

Description

+
This helper structure holds the relevant values for tracking the region of
+interest in a media file, called a segment.

+
The structure can be used for two purposes:

+
    
+
  • performing seeks (handling seek events)
    • 
+
  • tracking playback regions (handling newsegment events)
    • 
+

+
The segment is usually configured by the application with a seek event which
+is propagated upstream and eventually handled by an element that performs the seek.

+
The configured segment is then propagated back downstream with a newsegment event.
+This information is then used to clip media to the segment boundaries.

+
A segment structure is initialized with gst_segment_init(), which takes a GstFormat
+that will be used as the format of the segment values. The segment will be configured
+with a start value of 0 and a stop/duration of -1, which is undefined. The default
+rate and applied_rate is 1.0.

+
The public duration field contains the duration of the segment. When using
+the segment for seeking, the start and time members should normally be left
+to their default 0 value. The stop position is left to -1 unless explicitly
+configured to a different value after a seek event.

+
The current position in the segment should be set by changing the position
+member in the structure.

+
For elements that perform seeks, the current segment should be updated with the
+gst_segment_do_seek() and the values from the seek event. This method will update
+all the segment fields. The position field will contain the new playback position.
+If the start_type was different from GST_SEEK_TYPE_NONE, playback continues from
+the position position, possibly with updated flags or rate.

+
For elements that want to use GstSegment to track the playback region,
+update the segment fields with the information from the newsegment event.
+The gst_segment_clip() method can be used to check and clip
+the media data to the segment boundaries.

+
For elements that want to synchronize to the pipeline clock, gst_segment_to_running_time()
+can be used to convert a timestamp to a value that can be used to synchronize
+to the clock. This function takes into account the base as well as
+any rate or applied_rate conversions.

+
For elements that need to perform operations on media data in stream_time,
+gst_segment_to_stream_time() can be used to convert a timestamp and the segment
+info to stream time (which is always between 0 and the duration of the stream).

+

+

+
Functions

+

+
gst_segment_clip ()

+
gboolean
+gst_segment_clip (const GstSegment *segment,
+                  GstFormat format,
+                  guint64 start,
+                  guint64 stop,
+                  guint64 *clip_start,
+                  guint64 *clip_stop);

+
Clip the given start
+ and stop
+ values to the segment boundaries given
+in segment
+. start
+ and stop
+ are compared and clipped to segment
+
+start and stop values.

+
If the function returns FALSE, start
+ and stop
+ are known to fall
+outside of segment
+ and clip_start
+ and clip_stop
+ are not updated.

+
When the function returns TRUE, clip_start
+ and clip_stop
+ will be
+updated. If clip_start
+ or clip_stop
+ are different from start
+ or stop
+
+respectively, the region fell partially in the segment.

+
Note that when stop
+ is -1, clip_stop
+ will be set to the end of the
+segment. Depending on the use case, this may or may not be what you want.

+                     gdouble rate,
+                     GstFormat format,
+                     GstSeekFlags flags,

+                     guint64 stop,
+                     gboolean *update);

+
Update the segment structure with the field values of a seek event (see
+gst_event_new_seek()).

+
After calling this method, the segment field position and time will
+contain the requested new position in the segment. The new requested
+position in the segment depends on rate
+ and start_type
+ and stop_type
+.

+
For positive rate
+, the new position in the segment is the new segment
+
+start field when it was updated with a start_type
+ different from
+GST_SEEK_TYPE_NONE. If no update was performed on segment
+ start position
+(GST_SEEK_TYPE_NONE), start
+ is ignored and segment
+ position is
+unmodified.

+
For negative rate
+, the new position in the segment is the new segment
+
+stop field when it was updated with a stop_type
+ different from
+GST_SEEK_TYPE_NONE. If no stop was previously configured in the segment, the
+duration of the segment will be used to update the stop position.
+If no update was performed on segment
+ stop position (GST_SEEK_TYPE_NONE),
+stop
+ is ignored and segment
+ position is unmodified.

+
The applied rate of the segment will be set to 1.0 by default.
+If the caller can apply a rate change, it should update segment
+
+rate and applied_rate after calling this function.

+
update
+ will be set to TRUE if a seek should be performed to the segment
+position field. This field can be FALSE if, for example, only the rate
+
+has been changed but not the playback position.

+

+
Description

+
A GstStructure is a collection of key/value pairs. The keys are expressed
+as GQuarks and the values can be of any GType.

+
In addition to the key/value pairs, a GstStructure also has a name. The name
+starts with a letter and can be filled by letters, numbers and any of "/-_.:".

+
GstStructure is used by various GStreamer subsystems to store information
+in a flexible and extensible way. A GstStructure does not have a refcount
+because it usually is part of a higher level object such as GstCaps,
+GstMessage, GstEvent, GstQuery. It provides a means to enforce mutability
+using the refcount of the parent with the gst_structure_set_parent_refcount()
+method.

+
A GstStructure can be created with gst_structure_new_empty() or
+gst_structure_new(), which both take a name and an optional set of
+key/value pairs along with the types of the values.

+
Field values can be changed with gst_structure_set_value() or
+gst_structure_set().

+
Field values can be retrieved with gst_structure_get_value() or the more
+convenient gst_structure_get_*() functions.

+
Fields can be removed with gst_structure_remove_field() or
+gst_structure_remove_fields().

+
Strings in structures must be ASCII or UTF-8 encoded. Other encodings are
+not allowed. Strings may be NULL however.

+
Be aware that the current GstCaps / GstStructure serialization into string
+has limited support for nested GstCaps / GstStructure fields. It can only
+support one level of nesting. Using more levels will lead to unexpected
+behavior when using serialization features, such as gst_caps_to_string() or
+gst_value_serialize() and their counterparts.

structure
a GstStructure
 
name
structure name to check for
 

+

+

+
Returns

+
 TRUE if name
+matches the name of the structure.

+

+

+

+

+
gst_structure_set_name ()

+
void
+gst_structure_set_name (GstStructure *structure,
+                        const gchar *name);

+
Sets the name of the structure to the given name
+.  The string
+provided is copied before being used. It must not be empty, start with a
+letter and can be followed by letters, numbers and any of "/-_.:".

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





structure
a GstStructure
 
name
the new name of the structure
 

+

+

+

+

+
gst_structure_get_name_id ()

+
GQuark
+gst_structure_get_name_id (const GstStructure *structure);

+
Get the name of structure
+ as a GQuark.

+

+
Parameters

+

+++++
+
+
+
+
+
+





structure
a GstStructure
 

+

+

+
Returns

+
 the quark representing the name of the structure.

+

+

+

+

+
gst_structure_id_get ()

+
gboolean
+gst_structure_id_get (const GstStructure *structure,
+                      GQuark first_field_id,
+                      ...);

+
Parses the variable arguments and reads fields from structure
+ accordingly.
+Variable arguments should be in the form field id quark, field type
+(as a GType), pointer(s) to a variable(s) to hold the return value(s).
+The last variable argument should be NULL (technically it should be a
+0 quark, but we require NULL so compilers that support it can check for
+the NULL terminator and warn if it's not there).

+
This function is just like gst_structure_get() only that it is slightly
+more efficient since it saves the string-to-quark lookup in the global
+quark hashtable.

+
For refcounted (mini)objects you will receive a new reference which
+you must release with a suitable _unref() when no longer needed. For
+strings and boxed types you will receive a copy which you will need to
+release with either g_free() or the suitable function for the boxed type.

+
Description

+
The GStreamer core provides a GstSystemClock based on the system time.
+Asynchronous callbacks are scheduled from an internal thread.

+
Clock implementors are encouraged to subclass this systemclock as it
+implements the async notification.

+
Subclasses can however override all of the important methods for sync and
+async notifications to implement their own callback methods or blocking
+wait operations.

+

+

+
Functions

+

+
gst_system_clock_obtain ()

+
GstClock *
+gst_system_clock_obtain (void);

+
Get a handle to the default system clock. The refcount of the
+clock will be increased so you need to unref the clock after
+usage.

+

+
Returns

+
the default clock.

+
MT safe. 

+
[transfer full]

+

+

+

+

+
gst_system_clock_set_default ()

+
void
+gst_system_clock_set_default (GstClock *new_clock);

+
Sets the default system clock that can be obtained with
+gst_system_clock_obtain().

+
This is mostly used for testing and debugging purposes when you
+want to have control over the time reported by the default system
+clock.

+
MT safe.

GstTagMergeFunc ()

+
void
+(*GstTagMergeFunc) (GValue *dest,
+                    const GValue *src);

+
A function for merging multiple values of a tag used when registering
+tags.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+

src
the source GValue

gst_tag_register ()

+
void
+gst_tag_register (const gchar *name,
+                  GstTagFlag flag,
+                  GType type,
+                  const gchar *nick,
+                  const gchar *blurb,
+                  GstTagMergeFunc func);

+
Registers a new tag type for the use with GStreamer's type system. If a type
+with that name is already registered, that one is used.
+The old registration may have used a different type however. So don't rely
+on your supplied values.

+
Important: if you do not supply a merge function the implication will be
+that there can only be one single value for this tag in a tag list and
+any additional values will silently be discarded when being added (unless
+GST_TAG_MERGE_REPLACE, GST_TAG_MERGE_REPLACE_ALL, or
+GST_TAG_MERGE_PREPEND is used as merge mode, in which case the new
+value will replace the old one in the list).

+
The merge function will be called from gst_tag_list_copy_value() when
+it is required that one or more values for a tag be condensed into
+one single value. This may happen from gst_tag_list_get_string(),
+gst_tag_list_get_int(), gst_tag_list_get_double() etc. What will happen
+exactly in that case depends on how the tag was registered and if a
+merge function was supplied and if so which one.

+
Two default merge functions are provided: gst_tag_merge_use_first() and
+gst_tag_merge_strings_with_comma().

Checks if the given tag is fixed. A fixed tag can only contain one value.
+Unfixed tags can contain lists of values.

+

+
Parameters

GstTagList *
+gst_tag_list_new (const gchar *tag,
+                  ...);

+
Creates a new taglist and appends the values for the given tags. It expects
+tag-value pairs like gst_tag_list_add(), and a NULL terminator after the
+last pair. The type of the values is implicit and is documented in the API
+reference, but can also be queried at runtime with gst_tag_get_type(). It
+is an error to pass a value of a type not matching the tag type into this
+function. The tag list will make copies of any arguments passed
+(e.g. strings, buffers).

+
After creation you might also want to set a GstTagScope on the returned
+taglist to signal if the contained tags are global or stream tags. By
+default stream scope is assumes. See gst_tag_list_set_scope().

Checks if the given taglist is empty.

+

+
Parameters

+

+++++
+
+
+
+
+
+





list
A GstTagList.
 

+

+

+
Returns

+

+

+

+

+
gst_tag_list_is_equal ()

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





list1
a GstTagList.
 
list2
a GstTagList.
 

+

+

+
Returns

+
 TRUE if the taglists are equal, otherwise FALSE

+

+

+

+

+
gst_tag_list_copy ()

+
GstTagList *
+gst_tag_list_copy (const GstTagList *taglist);

+
Creates a new GstTagList as a copy of the old taglist
+. The new taglist
+will have a refcount of 1, owned by the caller, and will be writable as
+a result.

+
Note that this function is the semantic equivalent of a gst_tag_list_ref()
+followed by a gst_tag_list_make_writable(). If you only want to hold on to a
+reference to the data, you should use gst_tag_list_ref().

+
When you are finished with the taglist, call gst_tag_list_unref() on it.

+

+
Parameters

+

+++++
+
+
+
+
+
+





taglist
a GstTagList.
 

+

+

+
Returns

+
 the new GstTagList

+

+

+

+

+
gst_tag_list_ref ()

+
GstTagList *
+gst_tag_list_ref (GstTagList *taglist);

+
Add a reference to a GstTagList mini object.

+
From this point on, until the caller calls gst_tag_list_unref() or
+gst_tag_list_make_writable(), it is guaranteed that the taglist object will
+not change. To use a GstTagList object, you must always have a refcount on
+it -- either the one made implicitly by e.g. gst_tag_list_new(), or via
+taking one explicitly with this function.

+

+
Parameters

+

+++++
+
+
+
+
+
+





taglist
the GstTagList to reference
 

+

+

+
Returns

+
 the same GstTagList mini object.

+

+

+

+

+
gst_tag_list_unref ()

+
void
+gst_tag_list_unref (GstTagList *taglist);

+
Unref a GstTagList, and and free all its memory when the refcount reaches 0.

+

+
Parameters

+

+++++
+
+
+
+
+
+





taglist
a GstTagList.
 

+

+

+

+

+
gst_tag_list_is_writable()

+
#define gst_tag_list_is_writable(taglist)    gst_mini_object_is_writable (GST_MINI_OBJECT_CAST (taglist))
+

+
Tests if you can safely modify taglist
+. It is only safe to modify taglist
+when there is only one owner of the taglist - ie, the refcount is 1.

+

+
Parameters

+

+++++
+
+
+
+
+
+





taglist
a GstTagList
 

+

+

+

+

+
gst_tag_list_make_writable()

+
#define gst_tag_list_make_writable(taglist)   GST_TAG_LIST (gst_mini_object_make_writable (GST_MINI_OBJECT_CAST (taglist)))
+

+
Returns a writable copy of taglist
+.

+
If there is only one reference count on taglist
+, the caller must be the
+owner, and so this function will return the taglist object unchanged. If on
+the other hand there is more than one reference on the object, a new taglist
+object will be returned (which will be a copy of taglist
+). The caller's
+reference on taglist
+ will be removed, and instead the caller will own a
+reference to the returned object.

+
In short, this function unrefs the taglist in the argument and refs the
+taglist that it returns. Don't access the argument after calling this
+function. See also: gst_tag_list_ref().

+

+
Parameters

+

+++++
+
+
+
+
+
+





taglist
a GstTagList. 
[transfer full]

+

+

+
Returns

+
a writable taglist which may or may not be the

+

+

+
Prerequisites

+

+GstTagSetter requires
+ GstElement.

+

+

+
Includes

+
#include <gst/gstprotection.h>
+

+

+

+
Description

+
Element interface that allows setting of media metadata.

+
Elements that support changing a stream's metadata will implement this
+interface. Examples of such elements are 'vorbisenc', 'theoraenc' and
+'id3v2mux'.

+
If you just want to retrieve metadata in your application then all you
+need to do is watch for tag messages on your pipeline's bus. This
+interface is only for setting metadata, not for extracting it. To set tags
+from the application, find tagsetter elements and set tags using e.g.
+gst_tag_setter_merge_tags() or gst_tag_setter_add_tags(). Also consider
+setting the GstTagMergeMode that is used for tag events that arrive at the
+tagsetter element (default mode is to keep existing tags).
+The application should do that before the element goes to GST_STATE_PAUSED.

+
Elements implementing the GstTagSetter interface often have to merge
+any tags received from upstream and the tags set by the application via
+the interface. This can be done like this:

+
Description

+
GstTask is used by GstElement and GstPad to provide the data passing
+threads in a GstPipeline.

+
A GstPad will typically start a GstTask to push or pull data to/from the
+peer pads. Most source elements start a GstTask to push data. In some cases
+a demuxer element can start a GstTask to pull data from a peer element. This
+is typically done when the demuxer can perform random access on the upstream
+peer element for improved performance.

+
Although convenience functions exist on GstPad to start/pause/stop tasks, it
+might sometimes be needed to create a GstTask manually if it is not related to
+a GstPad.

+
Before the GstTask can be run, it needs a GRecMutex that can be set with
+gst_task_set_lock().

+
The task can be started, paused and stopped with gst_task_start(), gst_task_pause()
+and gst_task_stop() respectively or with the gst_task_set_state() function.

+
A GstTask will repeatedly call the GstTaskFunction with the user data
+that was provided when creating the task with gst_task_new(). While calling
+the function it will acquire the provided lock. The provided lock is released
+when the task pauses or stops.

+
Stopping a task with gst_task_stop() will not immediately make sure the task is
+not running anymore. Use gst_task_join() to make sure the task is completely
+stopped and the thread is stopped.

+
After creating a GstTask, use gst_object_unref() to free its resources. This can
+only be done when the task is not running anymore.

+
Task functions can send a GstMessage to send out-of-band data to the
+application. The application can receive messages from the GstBus in its
+mainloop.

+
For debugging purposes, the task will configure its object name as the thread
+name on Linux. Please note that the object name should be configured before the
+task is started; changing the object name after the task has been started, has
+no effect on the thread name.

+

+

+

Description

+
GstToc functions are used to create/free GstToc and GstTocEntry structures.
+Also they are used to convert GstToc into GstStructure and vice versa.

+
GstToc lets you to inform other elements in pipeline or application that playing
+source has some kind of table of contents (TOC). These may be chapters, editions,
+angles or other types. For example: DVD chapters, Matroska chapters or cue sheet
+TOC. Such TOC will be useful for applications to display instead of just a
+playlist.

+
Using TOC is very easy. Firstly, create GstToc structure which represents root
+contents of the source. You can also attach TOC-specific tags to it. Then fill
+it with GstTocEntry entries by appending them to the GstToc using
+gst_toc_append_entry(), and appending subentries to a GstTocEntry using
+gst_toc_entry_append_sub_entry().

+
Note that root level of the TOC can contain only either editions or chapters. You
+should not mix them together at the same level. Otherwise you will get serialization
+/deserialization errors. Make sure that no one of the entries has negative start and
+ stop values.

+
Use gst_event_new_toc() to create a new TOC GstEvent, and gst_event_parse_toc() to
+parse received TOC event. Use gst_event_new_toc_select() to create a new TOC select GstEvent,
+and gst_event_parse_toc_select() to parse received TOC select event. The same rule for
+the GstMessage: gst_message_new_toc() to create new TOC GstMessage, and
+gst_message_parse_toc() to parse received TOC message.

+
TOCs can have global scope or current scope. Global scope TOCs contain
+all entries that can possibly be selected using a toc select event, and
+are what an application is usually interested in. TOCs with current scope
+only contain the parts of the TOC relevant to the currently selected/playing
+stream; the current scope TOC is used by downstream elements such as muxers
+to write correct TOC entries when transcoding files, for example. When
+playing a DVD, the global TOC would contain a hierarchy of all titles,
+chapters and angles, for example, while the current TOC would only contain
+the chapters for the currently playing title if playback of a specific
+title was requested.

+
Applications and plugins should not rely on TOCs having a certain kind of
+structure, but should allow for different alternatives. For example, a
+simple CUE sheet embedded in a file may be presented as a flat list of
+track entries, or could have a top-level edition node (or some other
+alternative type entry) with track entries underneath that node; or even
+multiple top-level edition nodes (or some other alternative type entries)
+each with track entries underneath, in case the source file has extracted
+a track listing from different sources).

+

Description

+
Tracing modules will create instances of this class to announce the data they
+will log and create a log formatter.

+

+

+
Functions

+

+
gst_tracer_record_new ()

+
GstTracerRecord *
+gst_tracer_record_new (const gchar *name,
+                       const gchar *firstfield,
+                       ...);

+
Create a new tracer record. The record instance can be used to efficiently
+log entries using gst_tracer_record_log().

+
The name
+ without the ".class" suffix will be used for the log records.
+There must be fields for each value that gets logged where the field name is
+the value name. The field must be a GstStructure describing the value. The
+sub structure must contain a field called 'type' of G_TYPE_GTYPE that
+contains the GType of the value. The resulting GstTracerRecord will take
+ownership of the field structures.

+
The way to deal with optional values is to log an additional boolean before
+the optional field, that if TRUE signals that the optional field is valid
+and FALSE signals that the optional field should be ignored. One must still
+log a placeholder value for the optional field though. Please also note, that
+pointer type values must not be NULL - the underlying serialisation can not
+handle that right now.

+
Please note that this is still under discussion and subject to change.

gst_tracer_record_log ()

+
void
+gst_tracer_record_log (GstTracerRecord *self,
+                       ...);

+
Serialzes the trace event into the log.

+
Right now this is using the gstreamer debug log with the level TRACE (7) and
+the category "GST_TRACER".

+
Please note that this is still under discussion and subject to change.

+

+

+

+

+
enum GstTracerValueScope

+
Tracing record will contain fields that contain a meassured value or extra
+meta-data. One such meta data are values that tell where a measurement was
+taken. This enumerating declares to which scope such a meta data field
+relates to. If it is e.g. GST_TRACER_VALUE_SCOPE_PAD, then each of the log
+events may contain values for different GstPads.

+
Gets the list of all registered typefind factories. You must free the
+list using gst_plugin_feature_list_free().

+
The returned factories are sorted by highest rank first, and then by
+factory name.

+
Free-function: gst_plugin_feature_list_free

const gchar * const *
+gst_type_find_factory_get_extensions (GstTypeFindFactory *factory);

+
Gets the extensions associated with a GstTypeFindFactory. The returned
+array should not be changed. If you need to change stuff in it, you should
+copy it using g_strdupv().  This function may return NULL to indicate
+a 0-length list.

+

Building GStreamer and GStreamer Applications

+
Building GStreamer and GStreamer Applications — 
+How to build the GStreamer framework and applications using it.
+

+

+

+
Building GStreamer on UNIX

+

+    On UNIX, GStreamer uses the standard GNU build system,
+    using autoconf for package
+    configuration and resolving portability issues,
+    automake for building makefiles
+    that comply with the GNU Coding Standards, and
+    libtool for building shared
+    libraries on multiple platforms.  The normal sequence for
+    compiling and installing the GStreamer library is thus:
+
+    

+


+      ./configure

+      make

+      make install

+    

+

+  

+

+    The standard options provided by GNU
+    autoconf may be passed to the
+    configure script.  Please see the
+    autoconf documentation or run
+    ./configure --help for information about
+    the standard options.
+  

+

+    In addition there are several options to activate or deactivate features.
+    E.g. passing --disable-gst-debug to configure
+    will turn the debugging subsystem into a non-functional stub and remove all
+    macro based invocations from within the library (and anything compiled
+    against the library afterwards.)
+  

+

+    If library size matters and one builds in a controlled environment, it is
+    also possible to totally remove subsystem code. This is intentionally not
+    offered as a configure option as it causes an ABI break. Code built against
+    a version of GStreamer without these modifications needs to be recompiled.
+
+    

+


+      make CFLAGS="-DGST_REMOVE_DEPRECATED -DGST_REMOVE_DISABLED"

+    

+

+
+    

+
    
+
  • 
+          GST_REMOVE_DEPRECATED - Omit deprecated functions
+          from the library.
+        
    • 
+
  • 
+          GST_REMOVE_DISABLED - Omit stubs for disabled
+          subsystems from the library.
+        
    • 
+

+

+  

+

+

+
Building GStreamer Applications

+

+Applications and libraries can use pkg-config to get all the
+needed compiler and linker flags to build against GStreamer. Please note that
+GStreamer is split into several libraries itself.
+pkg-config --list-all | grep gstreamer will list the
+available libraries.

+How to run and debug your GStreamer application
+

+

+
Running and debugging GStreamer Applications

+

+
Environment variables

+
 
+GStreamer inspects a few of environment variables in addition to standard
+variables like LANG, PATH or HOME. 
+

+
GST_PLUGIN_SYSTEM_PATH,
+         GST_PLUGIN_SYSTEM_PATH_1_0. 
+
+This environment variable can be set to a colon-separated list of paths (or
+semicolon-separated list on Windows).
+If this variable is not set, GStreamer will fill in this list for you
+with
+

+
    
+
  • 
+plug-ins in the user's home directory, or rather the user's "data home"
+directory according to the xdg base dir specification. Usually this will be
+a directory called
+plugins inside the
+.local/share/gstreamer-1.0 directory in
+the user's home directory by default, though this search path may change if
+the XDG_DATA_HOME environment variable is set.
+    
    • 
+
  • 
+plug-ins installed system-wide.  On this system, they are stored in
+/usr/local/lib/gstreamer-1.0.
+    
    • 
+

+

+   
+GStreamer will scan these paths for GStreamer plug-ins.  These plug-ins will
+be loaded after the plug-ins in the GST_PLUGIN_PATH variable below.
+
+The paths are scanned in the given order.  This allows a user to override
+system-installed plug-ins with his own versions.
+   
+The GST_PLUGIN_SYSTEM_PATH_1_0 variant is useful if both the old GStreamer 0.10
+version and the new GStreamer 1.0 version need to be pointed to new plugin
+paths. The latter will use the _1_0 variant over the non-versioned one if
+it is set.
+  
+Setting this variable to an empty string will cause GStreamer not to scan any
+system paths at all for plug-ins.  This can be useful if you're running
+uninstalled (for development purposes) or while running testsuites.
+   

+
GST_PLUGIN_PATH, GST_PLUGIN_PATH_1_0. 
+This environment variable can be set to a colon-separated list of paths (or a
+semicolon-separated list on Windows).
+GStreamer will scan these paths for GStreamer plug-ins.  These plug-ins will
+be loaded in addition to, and before, the plug-ins in the system paths.
+  
+The GST_PLUGIN_PATH_1_0 variant is useful if both the old GStreamer 0.10
+version and the new GStreamer 1.0 version need to be pointed to new plugin
+paths. The latter will use the _1_0 variant over the non-versioned one if
+it is set.
+  

+
GST_DEBUG. 
+If GStreamer has been configured with --enable-gst-debug=yes,
+this variable can be set to a list of debug options, which cause GStreamer
+to print out different types of debugging information to stderr.
+  
+The variable takes a comma-separated list of "category_name:level" pairs
+to set specific levels for the individual categories.
+The level value ranges from 0 (nothing) to 9 (MEMDUMP).

+Logs all fixme messages. Fixme messages are messages that indicate that something
+in the executed code path is not fully implemented or handled yet.  The purpose
+of this message is to make it easier to spot incomplete/unfinished pieces of
+code when reading the debug log.
+
4 - INFO

+Logs all informational messages.  These are typically used for events in
+the system that only happen once, or are important and rare enough to be
+logged at this level.
+
5 - DEBUG

+Logs all debug messages.  These are general debug messages for events
+that happen only a limited number of times during an object's lifetime;
+these include setup, teardown, change of parameters, ...
+
6 - LOG

+Logs all log messages.  These are messages for events
+that happen repeatedly during an object's lifetime;
+these include streaming and steady-state conditions.
+
7 - TRACE

+Logs all trace messages.  These messages for events
+that happen repeatedly during an object's lifetime such as the
+ref/unref cycles.
+
9 - MEMDUMP

+Log all memory dump messages. Memory dump messages are used to log
+(small) chunks of data as memory dumps in the log. They will be displayed
+as hexdump with ASCII characters.
+

+

+
+ The category_name can contain "*" as a wildcard.
+  
+For example, setting GST_DEBUG to
+GST_AUTOPLUG:6,GST_ELEMENT_*:4, will cause the
+GST_AUTOPLUG category to be logged at full
+LOG level, while all categories starting with
+GST_ELEMENT_ will be logged at INFO level.
+  
+To get all possible debug output, set
+GST_DEBUG
+to *:9. For debugging purposes a *:6 debug
+log is usually the most useful, as it contains all important information, but
+hides a lot of noise such as refs/unrefs. For bug reporting purposes, a
+*:6 log is also what will be requested usually. It's often
+also worth running with *:3 to see if there are any
+non-fatal errors or warnings that might be related to the problem at hand.
+  
+Since GStreamer 1.2 it is also possible to specify debug levels by name,
+e.g. GST_DEBUG=*:WARNING,*audio*:LOG
+  

+
GST_DEBUG_NO_COLOR. 
+Set this environment variable to any value ("1" typically) to switch off
+colouring in GST_DEBUG output. This has the same effect as specifying the
+--gst-debug-no-color or
+--gst-debug-color-mode=off command line option to
+well-behaved GStreamer applications (ie. those that pass command-line
+options correctly to GStreamer).
+This is particularly useful to reduce the size of debug output and also allows
+for the output to be compressed much better than with colours turned on.
+  
+Has the same effect as setting GST_DEBUG_COLOR_MODE environment variable to
+"off".
+  

+
GST_DEBUG_COLOR_MODE. 
+Set this environment variable to change log colouring in GST_DEBUG output.
+Possible values:
+

on

+Enables debug log output coloring. Uses default coloring method for current
+platform. This is the default.
+          
off

+

+Disables debug log output coloring. This has the same effect as specifying the
+--gst-debug-color-mode=off command line option to
+well-behaved GStreamer applications (ie. those that pass command-line
+options correctly to GStreamer).
+This is particularly useful to reduce the size of debug output and also allows
+for the output to be compressed much better than with colours turned on.
+          

+

+Has the same effect as setting GST_DEBUG_NO_COLOR environment variable to
+any value.
+          

+
auto

+Same as on.
+          
disable

+Same as off.
+          
unix

+Enables debug log output coloring and forces the use of UNIX termial codes
+for coloring, even if this method is not normally used on current platform.
+This has the same effect as specifying the
+--gst-debug-color-mode=unix command line option to
+well-behaved GStreamer applications (ie. those that pass command-line options
+correctly to GStreamer).
+This is particularly useful to dump debug output into a file on non-UNIX
+platforms to be sent to developers who have viewers that support UNIX terminal
+codes.
+          

+

+  

+
GST_DEBUG_OPTIONS. 
+This environment variable can be used to tweak the behaviour of the debugging
+system. Currently the only options supported are "pretty-tags" and "full-tags".
+In "pretty-tags" mode (the default), taglists in the debug log will be
+serialized so that only the first few and last few bytes of a buffer-type tag
+will be serialized into the log, to avoid dumping hundreds of lines of useless
+output into the log in case of large image tags and the like.
+  

+
GST_DEBUG_DUMP_DOT_DIR. 
+Set this environment variable to a path to turn on all
+#GST_DEBUG_BIN_TO_DOT_FILE or #GST_DEBUG_BIN_TO_DOT_FILE_WITH_TS calls
+and have the dot files in that location.
+  
+This will only work if the application in question makes these calls in
+strategic places (like when the pipeline state changes or an error occurs).
+gst-launch-1.0 is one such application.
+  
+When gst-launch-1.0 changes state through NULL to PLAYING
+and back to NULL, a dot file is generated on each state change. To have
+gst-launch-1.0 write a snapshot of the pipeline state, send
+a SIGHUP to the gst-launch-1.0 process.
+  
+These .dot files can then be turned into images using the 'dot' utility
+from the graphviz set of tools, like this:
+  dot foo.dot -Tsvg -o foo.svg or
+  dot foo.dot -Tpng -o foo.png or
+  dot foo.dot -Tjpg -o foo.jpg.
+  
+There is also a utility called xdot which allows you to
+view the dot file directly without converting it first.
+  

+
GST_REGISTRY, GST_REGISTRY_1_0. 
+Set this environment variable to make GStreamer use a different file for the
+plugin cache / registry than the default one. This is useful when operating
+in a separate environment which should not affect the default cache in the
+user's home directory.
+  

+
GST_REGISTRY_FORK. 
+Set this environment variable to "no" to prevent GStreamer from forking on
+startup in order to update the plugin registry. This is useful for debugging
+purposes, but should not be used under normal circumstances, since it means
+that plugins may be loaded into memory even if they are not needed by the
+application.
+  

+
GST_REGISTRY_UPDATE. 
+Set this environment variable to "no" to prevent GStreamer from updating the
+plugin registry. This is useful for embedded device which is not updating the
+plugins frequently, it will save time when doing gst_init().
+  

+
GST_TRACE. 
+    Enable memory allocation tracing. Most GStreamer objects have support for
+    tracing the number of unfreed objects and their memory pointers.
+  
+The variable takes a comma-separated list of tracing options to enable.
+    

+

++++
+
+
+
+
+
+
+
+
+
+
+




live

+  Counts all live objects and dumps an overview of the number of unfreed
+  objects at program exit.
+
mem-live

+  Keep track of the unfreed memory pointers and dump an overview of all unfreed
+  memory at program exit. Together with a level 9 debug log this can be used to
+  follow the lifecycle of leaked objects in order to track down where they are
+  leaked. This can be useful for debugging memory leaks in situations where
+  tools such as valgrind are not available, or not an option.
+

+

+
+ Use all to enable all tracing flags.
+  

+
GST_DEBUG_FILE. 
+  Set this variable to a file path to redirect all GStreamer debug
+  messages to this file. If left unset, debug messages with be output
+  unto the standard error.
+  

+
ORC_CODE. 
+Useful Orc environment variable. Set ORC_CODE=debug to enable debuggers
+such as gdb to create useful backtraces from Orc-generated code.  Set
+ORC_CODE=backup or ORC_CODE=emulate if you suspect Orc's SIMD code
+generator is producing incorrect code (Quite a few important
+GStreamer plugins like videotestsrc, audioconvert or audioresample use Orc).
+One can also combine flags like ORC_CODE=backup,debug.
+  

+
G_DEBUG. 
+Useful GLib environment variable. Set G_DEBUG=fatal_warnings to make
+GStreamer programs abort when a critical warning such as an assertion failure
+occurs. This is useful if you want to find out which part of the code caused
+that warning to be triggered and under what circumstances. Simply set G_DEBUG
+as mentioned above and run the program in gdb (or let it core dump). Then get
+a stack trace in the usual way.
+  

+
G_SLICE. 
+Useful GLib environment variable. Set G_SLICE=always-malloc when running
+GStreamer programs in valgrind, or debugging memory leaks with other tools.
+See the GLib API reference for more details.
+  

+
GST_TAG_ENCODING. 
+Try this character encoding first for tag-related strings where the encoding
+is not defined and which are not UTF-8 already. By default the current locale
+will be tried (if not UTF-8).
+  

+
GST_TAG_ID3_ENCODING. 
+Try this character encoding first for ID3 tag-related strings where the
+encoding is not defined and which are not UTF-8 already. By default the current
+locale will be tried (if not UTF-8).
+  

+
GST_TAG_ID3V1_ENCODING. 
+Try this character encoding first for ID3v1 tag-related strings where the
+encoding does not look like UTF-8.
+  

+
GST_GL_WINDOW. 
+Influences the window system to use by the GStreamer OpenGL library.
+Common values are 'x11', 'wayland', 'win32' or 'cocoa'.
+  

+
GST_GL_PLATFORM. 
+Influences the OpenGL platform to use by the GStreamer OpenGL library.
+Common values are 'egl', 'glx', 'wgl' or 'cgl'.
+  

+
GST_GL_API. 
+Influences the OpenGL API requested by the OpenGL platform.
+Common values are 'opengl' or 'gles2'.
+

Description

+
GStreamer is a framework for constructing graphs of various filters
+(termed elements here) that will handle streaming media.  Any discrete
+(packetizable) media type is supported, with provisions for automatically
+determining source type.  Formatting/framing information is provided with
+a powerful negotiation framework.  Plugins are heavily used to provide for
+all elements, allowing one to construct plugins outside of the GST
+library, even released binary-only if license require (please don't).
+GStreamer covers a wide range of use cases including: playback, recording,
+editing, serving streams, voice over ip and video calls.

+
The GStreamer library should be initialized with
+gst_init() before it can be used. You should pass pointers to the main argc
+and argv variables so that GStreamer can process its own command line
+options, as shown in the following example.

+

+
Initializing the gstreamer library

int
+main (int argc, char *argv[])
+{
+  // initialize the GStreamer library
+  gst_init (&argc, &argv);
+  ...
+}

+

+
+

+
It's allowed to pass two NULL pointers to gst_init() in case you don't want
+to pass the command line args to GStreamer.

+
You can also use GOption to initialize your own parameters as shown in
+the next code fragment:

+

+

+  {"tags", 't', 0, G_OPTION_ARG_NONE, &tags,
+      N_("Output tags (also known as metadata)"), NULL},
+  {NULL}
+ };
+ ctx = g_option_context_new ("[ADDITIONAL ARGUMENTS]");
+ g_option_context_add_main_entries (ctx, options, GETTEXT_PACKAGE);
+ g_option_context_add_group (ctx, gst_init_get_option_group ());
+ if (!g_option_context_parse (ctx, &argc, &argv, &err)) {
+   g_print ("Error initializing: %s\n", GST_STR_NULL (err->message));
+   exit (1);
+ }
+ g_option_context_free (ctx);
+...
+}

+

+
+

+
Use gst_version() to query the library version at runtime or use the
+GST_VERSION_* macros to find the version at compile time. Optionally
+gst_version_string() returns a printable string.

+
The gst_deinit() call is used to clean up all internal resources used
+by GStreamer. It is mostly used in unit tests to check for leaks.

+

+

+

+
Functions

+

+
gst_init ()

+
void
+gst_init (int *argc,
+          char **argv[]);

+
Initializes the GStreamer library, setting up internal path lists,
+registering built-in elements, and loading standard plugins.

+
Unless the plugin registry is disabled at compile time, the registry will be
+loaded. By default this will also check if the registry cache needs to be
+updated and rescan all plugins if needed. See gst_update_registry() for
+details and section

+Running GStreamer Applications
for how to disable automatic registry updates.

+
This function will terminate your program if it was unable to initialize
+GStreamer for some reason.  If you want your program to fall back,
+use gst_init_check() instead.

+
WARNING: This function does not work in the same way as corresponding
+functions in other glib-style libraries, such as gtk_init(). In
+particular, unknown command line options cause this function to
+abort program execution.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





argc
pointer to application's argc. 
[inout][allow-none]
argv
pointer to application's argv. 
[inout][array length=argc][allow-none]

+

+

+

+

+
gst_init_check ()

+
gboolean
+gst_init_check (int *argc,
+                char **argv[],
+                GError **err);

+
Initializes the GStreamer library, setting up internal path lists,
+registering built-in elements, and loading standard plugins.

+
This function will return FALSE if GStreamer could not be initialized
+for some reason.  If you want your program to fail fatally,
+use gst_init() instead.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+





argc
pointer to application's argc. 
[inout][allow-none]
argv
pointer to application's argv. 
[inout][array length=argc][allow-none]
err
pointer to a GError to which a message will be posted on error
 

+

+

+
Returns

+
 TRUE if GStreamer could be initialized.

+

+

+

+

+
gst_init_get_option_group ()

+
GOptionGroup *
+gst_init_get_option_group (void);

+
Returns a GOptionGroup with GStreamer's argument specifications. The
+group is set up to use standard GOption callbacks, so when using this
+group in combination with GOption parsing methods, all argument parsing
+and initialization is automated.

+
This function is useful if you want to integrate GStreamer with other
+libraries that use GOption (see g_option_context_add_group() ).

+
If you use this function, you should make sure you initialise the GLib
+threading system as one of the very first things in your program
+(see the example at the beginning of this section).

+
[skip]

+

+
Returns

+
a pointer to GStreamer's option group. 

+
[transfer full][nullable]

+

+

+

+

+
gst_is_initialized ()

+
gboolean
+gst_is_initialized (void);

+
Use this function to check if GStreamer has been initialized with gst_init()
+or gst_init_check().

+

+
Returns

+
 TRUE if initialization has been done, FALSE otherwise.

+

+

+

+

+
gst_deinit ()

+
void
+gst_deinit (void);

+
Clean up any resources created by GStreamer in gst_init().

+
It is normally not needed to call this function in a normal application
+as the resources will automatically be freed when the program terminates.
+This function is therefore mostly used by testsuites and other memory
+profiling tools.

+
After this call GStreamer (including this method) should not be used anymore.

+

+

+

+
gst_version ()

+
void
+gst_version (guint *major,
+             guint *minor,
+             guint *micro,
+             guint *nano);

+
Gets the version number of the GStreamer library.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+





major
pointer to a guint to store the major version number. 
[out]
minor
pointer to a guint to store the minor version number. 
[out]
micro
pointer to a guint to store the micro version number. 
[out]
nano
pointer to a guint to store the nano version number. 
[out]

+

+

+

+

+
gst_version_string ()

+
gchar *
+gst_version_string (void);

+
This function returns a string that is useful for describing this version
+of GStreamer to the outside world: user agent strings, logging, ...

+

+
Returns

+
a newly allocated string describing this version
+of GStreamer. 

+
[transfer full]

+

+

+

+

+
gst_segtrap_is_enabled ()

+
gboolean
+gst_segtrap_is_enabled (void);

+
Some functions in the GStreamer core might install a custom SIGSEGV handler
+to better catch and report errors to the application. Currently this feature
+is enabled by default when loading plugins.

+
Applications might want to disable this behaviour with the
+gst_segtrap_set_enabled() function. This is typically done if the application
+wants to install its own handler without GStreamer interfering.

+

+
Returns

+
 TRUE if GStreamer is allowed to install a custom SIGSEGV handler.

+

+

+

+

+
gst_segtrap_set_enabled ()

+
void
+gst_segtrap_set_enabled (gboolean enabled);

+
Applications might want to disable/enable the SIGSEGV handling of
+the GStreamer core. See gst_segtrap_is_enabled() for more information.

+

+
Parameters

+

+++++
+
+
+
+
+
+





enabled
whether a custom SIGSEGV handler should be installed.
 

+

+

+

+

+
gst_registry_fork_is_enabled ()

+
gboolean
+gst_registry_fork_is_enabled (void);

+
By default GStreamer will perform scanning and rebuilding of the
+registry file using a helper child process.

+
Applications might want to disable this behaviour with the
+gst_registry_fork_set_enabled() function, in which case new plugins
+are scanned (and loaded) into the application process.

+

+
Returns

+
 TRUE if GStreamer will use the child helper process when
+rebuilding the registry.

+

+

+

+

+
gst_registry_fork_set_enabled ()

+
void
+gst_registry_fork_set_enabled (gboolean enabled);

+
Applications might want to disable/enable spawning of a child helper process
+when rebuilding the registry. See gst_registry_fork_is_enabled() for more
+information.

+

+
Parameters

+

+++++
+
+
+
+
+
+





enabled
whether rebuilding the registry can use a temporary child helper process.
 

+

+

+

+

+
gst_update_registry ()

+
gboolean
+gst_update_registry (void);

+
Forces GStreamer to re-scan its plugin paths and update the default
+plugin registry.

+
Applications will almost never need to call this function, it is only
+useful if the application knows new plugins have been installed (or old
+ones removed) since the start of the application (or, to be precise, the
+first call to gst_init()) and the application wants to make use of any
+newly-installed plugins without restarting the application.

+
Applications should assume that the registry update is neither atomic nor
+thread-safe and should therefore not have any dynamic pipelines running
+(including the playbin and decodebin elements) and should also not create
+any elements or access the GStreamer registry while the update is in
+progress.

+
Note that this function may block for a significant amount of time.

+

+
Returns

+
 TRUE if the registry has been updated successfully (does not
+imply that there were changes), otherwise FALSE.

+

+

+

+

+
gst_get_main_executable_path ()

+
const gchar *
+gst_get_main_executable_path (void);

+
This helper is mostly helpful for plugins that need to
+inspect the folder of the main executable to determine
+their set of features.

+
When a plugin is initialized from the gst-plugin-scanner
+external process, the returned path will be the same as from the
+parent process.

+

+
Returns

+
The path of the executable that
+initialized GStreamer, or NULL if it could not be determined.

Description

+
This describes the configuration options for GStreamer. When building
+GStreamer there are a lot of parts (known internally as "subsystems" ) that
+can be disabled for various reasons. The most common reasons are speed and
+size, which is important because GStreamer is designed to run on embedded
+systems.

+
If a subsystem is disabled, most of this changes are done in an API
+compatible way, so you don't need to adapt your code in most cases. It is
+never done in an ABI compatible way though. So if you want to disable a
+subsystem, you have to rebuild all programs depending on GStreamer, too.

+
If a subsystem is disabled in GStreamer, a value is defined in
+<gst/gst.h>. You can check this if you do subsystem-specific stuff.

+

Description

+
Applications should create a GstDeviceMonitor when they want
+to probe, list and monitor devices of a specific type. The
+GstDeviceMonitor will create the appropriate
+GstDeviceProvider objects and manage them. It will then post
+messages on its GstBus for devices that have been added and
+removed.

+
The device monitor will monitor all devices matching the filters that
+the application has set.

+
The basic use pattern of a device monitor is as follows:

+
Adds a filter for which GstDevice will be monitored, any device that matches
+all these classes and the GstCaps will be returned.

+
If this function is called multiple times to add more filters, each will be
+matched independently. That is, adding more filters will not further restrict
+what devices are matched.

The GstCaps supported by the device as returned by gst_device_get_caps() are
+not intersected with caps filters added using this function.

Description

+
A GstDeviceProvider subclass is provided by a plugin that handles devices
+if there is a way to programatically list connected devices. It can also
+optionally provide updates to the list of connected devices.

+
Each GstDeviceProvider subclass is a singleton, a plugin should
+normally provide a single subclass for all devices.

+
Applications would normally use a GstDeviceMonitor to monitor devices
+from all relevant providers.

+

+

+
Functions

+

+
gst_device_provider_can_monitor ()

+
gboolean
+gst_device_provider_can_monitor (GstDeviceProvider *provider);

Description

+
GStreamer elements can throw non-fatal warnings and fatal errors.
+Higher-level elements and applications can programmatically filter
+the ones they are interested in or can recover from,
+and have a default handler handle the rest of them.

+
The rest of this section will use the term “error”
+to mean both (non-fatal) warnings and (fatal) errors; they are treated
+similarly.

+
Errors from elements are the combination of a GError and a debug string.
+The GError contains:

+
    
+
  • a domain type: CORE, LIBRARY, RESOURCE or STREAM
    • 
+
  • a code: an enum value specific to the domain
    • 
+
  • a translated, human-readable message
    • 
+
  • a non-translated additional debug string, which also contains
    • 
+
  • file and line information
    • 
+

+
Elements do not have the context required to decide what to do with
+errors.  As such, they should only inform about errors, and stop their
+processing.  In short, an element doesn't know what it is being used for.

+
It is the application or compound element using the given element that
+has more context about the use of the element. Errors can be received by
+listening to the GstBus of the element/pipeline for GstMessage objects with
+the type GST_MESSAGE_ERROR or GST_MESSAGE_WARNING. The thrown errors should
+be inspected, and filtered if appropriate.

+
An application is expected to, by default, present the user with a
+dialog box (or an equivalent) showing the error message.  The dialog
+should also allow a way to get at the additional debug information,
+so the user can provide bug reporting information.

+
A compound element is expected to forward errors by default higher up
+the hierarchy; this is done by default in the same way as for other types
+of GstMessage.

+
When applications or compound elements trigger errors that they can
+recover from, they can filter out these errors and take appropriate action.
+For example, an application that gets an error from xvimagesink
+that indicates all XVideo ports are taken, the application can attempt
+to use another sink instead.

+
Elements throw errors using the GST_ELEMENT_ERROR convenience macro:

+

+    
+  
1
+2
GST_ELEMENT_ERROR (src, RESOURCE, NOT_FOUND,
+  (_("No file name specified for reading.")), (NULL));

+

+
+

+
Things to keep in mind:

+
    
+
  • Don't go off inventing new error codes.  The ones
+currently provided should be enough.  If you find your type of error
+does not fit the current codes, you should use FAILED.
    • 
+
  • Don't provide a message if the default one suffices.
+this keeps messages more uniform.  Use (NULL) - not forgetting the
+parentheses.
    • 
+
  • If you do supply a custom message, it should be
+marked for translation.  The message should start with a capital
+and end with a period.  The message should describe the error in short,
+in a human-readable form, and without any complex technical terms.
+A user interface will present this message as the first thing a user
+sees.  Details, technical info, ... should go in the debug string.
    • 
+
  • The debug string can be as you like.  Again, use (NULL)
+if there's nothing to add - file and line number will still be
+passed.  GST_ERROR_SYSTEM can be used as a shortcut to give
+debug information on a system call error.

Description

+
GStreamer's debugging subsystem is an easy way to get information about what
+the application is doing.  It is not meant for programming errors. Use GLib
+methods (g_warning and friends) for that.

+
The debugging subsystem works only after GStreamer has been initialized

+

+
The debugging subsystem is used to log informational messages while the
+application runs.  Each messages has some properties attached to it. Among
+these properties are the debugging category, the severity (called "level"
+here) and an optional GObject it belongs to. Each of these messages is sent
+to all registered debugging handlers, which then handle the messages.
+GStreamer attaches a default handler on startup, which outputs requested
+messages to stderr.

+
Messages are output by using shortcut macros like GST_DEBUG,
+GST_CAT_ERROR_OBJECT or similar. These all expand to calling gst_debug_log()
+with the right parameters.
+The only thing a developer will probably want to do is define his own
+categories. This is easily done with 3 lines. At the top of your code,
+declare
+the variables and set the default category.

+

+  
+    
+      
+        
+        
+      
+    
+  
1
+2
GST_DEBUG_CATEGORY_STATIC (my_category);  // define category (statically)
+#define GST_CAT_DEFAULT my_category       // set as default

+

+
+

+After that you only need to initialize the category.

+

+  
+    
+      
+        
+        
+      
+    
+  
1
+2
GST_DEBUG_CATEGORY_INIT (my_category, "my category",
+                         0, "This is my very own");

+

+
+

+Initialization must be done before the category is used first.
+Plugins do this
+in their plugin_init function, libraries and applications should do that
+during their initialization.

+
The whole debugging subsystem can be disabled at build time with passing the
+--disable-gst-debug switch to configure. If this is done, every function,
+macro and even structs described in this file evaluate to default values or
+nothing at all.
+So don't take addresses of these functions or use other tricks.
+If you must do that for some reason, there is still an option.
+If the debugging
+subsystem was compiled out, GST_DISABLE_GST_DEBUG is defined in
+<gst/gst.h>,
+so you can check that before doing your trick.
+Disabling the debugging subsystem will give you a slight (read: unnoticeable)
+speed increase and will reduce the size of your compiled code. The GStreamer
+library itself becomes around 10% smaller.

+
Please note that there are naming conventions for the names of debugging
+categories. These are explained at GST_DEBUG_CATEGORY_INIT().

+

+

+
Functions

+

+
GST_STR_NULL()

+
#define GST_STR_NULL(str) ((str) ? (str) : "(NULL)")
+

+
Macro to use when a string must not be NULL, but may be NULL. If the string
+is NULL, "(NULL)" is printed instead.
+In GStreamer printf string arguments may not be NULL, because on some
+platforms (ie Solaris) the libc crashes in that case. This includes debugging
+strings.

+

+
Parameters

+

+++++
+
+
+
+
+
+





str
The string to check. 
[allow-none]

+

+

+

+

+
GST_DEBUG_PAD_NAME()

+
#define             GST_DEBUG_PAD_NAME(pad)

+
Evaluates to 2 strings, that describe the pad. Often used in debugging
+statements.

+

+
Parameters

+

+++++
+
+
+
+
+
+





pad
The pad to debug.

GST_DEBUG_CATEGORY_INIT()

+
#define             GST_DEBUG_CATEGORY_INIT(cat,name,color,description)

+
Initializes a new GstDebugCategory with the given properties and set to
+the default threshold.

+

+
This macro expands to nothing if debugging is disabled.

+
When naming your category, please follow the following conventions to ensure
+that the pattern matching for categories works as expected. It is not
+earth-shattering if you don't follow these conventions, but it would be nice
+for everyone.

+
If you define a category for a plugin or a feature of it, name the category
+like the feature. So if you wanted to write a "filesrc" element, you would
+name the category "filesrc". Use lowercase letters only.
+If you define more than one category for the same element, append an
+underscore and an identifier to your categories, like this: "filesrc_cache"

+
If you create a library or an application using debugging categories, use a
+common prefix followed by an underscore for all your categories. GStreamer
+uses the GST prefix so GStreamer categories look like "GST_STATES". Be sure
+to include uppercase letters.

GST_DEBUG_BIN_TO_DOT_FILE()

+
#define GST_DEBUG_BIN_TO_DOT_FILE(bin, details, file_name) gst_debug_bin_to_dot_file (bin, details, file_name)
+

+
To aid debugging applications one can use this method to write out the whole
+network of gstreamer elements that form the pipeline into an dot file.
+This file can be processed with graphviz to get an image, like this:

+

+  
+    
+      
+        
+        
+      
+    
+  
1
dot -Tpng -oimage.png graph_lowlevel.dot

+

+
+

+There is also a utility called xdot which allows you to view the dot file
+directly without converting it first.

+
The macro is only active if gstreamer is configured with
+"--gst-enable-gst-debug" and the environment variable
+GST_DEBUG_DUMP_DOT_DIR is set to a basepath (e.g. /tmp).

+

+

GST_LEVEL_NONE

+
No debugging level specified or desired. Used to deactivate
+ debugging output.

+		 
GST_LEVEL_ERROR

+
Error messages are to be used only when an error occurred
+ that stops the application from keeping working correctly.
+ An examples is gst_element_error, which outputs a message with this priority.
+ It does not mean that the application is terminating as with g_error.

+		 
GST_LEVEL_WARNING

+
Warning messages are to inform about abnormal behaviour
+ that could lead to problems or weird behaviour later on. An example of this
+ would be clocking issues ("your computer is pretty slow") or broken input
+ data ("Can't synchronize to stream.")

+		 
GST_LEVEL_FIXME

+
Fixme messages are messages that indicate that something
+ in the executed code path is not fully implemented or handled yet. Note
+ that this does not replace proper error handling in any way, the purpose
+ of this message is to make it easier to spot incomplete/unfinished pieces
+ of code when reading the debug log.

+		 
GST_LEVEL_INFO

+
Informational messages should be used to keep the developer
+ updated about what is happening.
+ Examples where this should be used are when a typefind function has
+ successfully determined the type of the stream or when an mp3 plugin detects
+ the format to be used. ("This file has mono sound.")

+		 
GST_LEVEL_DEBUG

+
Debugging messages should be used when something common
+ happens that is not the expected default behavior, or something that's
+ useful to know but doesn't happen all the time (ie. per loop iteration or
+ buffer processed or event handled).
+ An example would be notifications about state changes or receiving/sending
+ of events.

+		 
GST_LEVEL_LOG

+
Log messages are messages that are very common but might be
+ useful to know. As a rule of thumb a pipeline that is running as expected
+ should never output anything else but LOG messages whilst processing data.
+ Use this log level to log recurring information in chain functions and
+ loop functions, for example.

+		 
GST_LEVEL_TRACE

+
Tracing-related messages.
+ Examples for this are referencing/dereferencing of objects.

+		 
GST_LEVEL_MEMDUMP

+
memory dump messages are used to log (small) chunks of
+ data as memory dumps in the log. They will be displayed as hexdump with
+ ASCII characters.

+		 
GST_LEVEL_COUNT

+
The number of defined debugging levels.

+		 

+

+

+

+

+
GST_LEVEL_DEFAULT

+
#define GST_LEVEL_DEFAULT GST_LEVEL_NONE
+

+
Defines the default debugging level to be used with GStreamer. It is normally
+set to GST_LEVEL_NONE so nothing get printed.
+As it can be configured at compile time, developer builds may chose to
+override that though.
+You can use this as an argument to gst_debug_set_default_threshold() to
+reset the debugging output to default behaviour.

+

+

+

+
GST_LEVEL_MAX

+
#define GST_LEVEL_MAX GST_LEVEL_COUNT
+

+
Defines the maximum debugging level to be enabled at compilation time. By default
+it is set such that all debugging statements will be enabled.

+
If you wish to compile GStreamer and plugins with only some debugging statements
+(Such as just warnings and errors), you can define it at compile time to the
+maximum debug level. Any debug statements above that level will be compiled out.

+
Since: 1.6

+

+

+

+
enum GstDebugColorFlags

+
These are some terminal style flags you can use when creating your
+debugging categories to make them stand out in debugging output.

Description

+
A GstIterator is used to retrieve multiple objects from another object in
+a threadsafe way.

+
Various GStreamer objects provide access to their internal structures using
+an iterator.

+
Note that if calling a GstIterator function results in your code receiving
+a refcounted object (with, say, g_value_get_object()), the refcount for that
+object will not be increased. Your code is responsible for taking a reference
+if it wants to continue using it later.

+
The basic use pattern of an iterator is as follows:

+

+while (!done) {

+    case GST_ITERATOR_OK:
+      ...get/use/change item here...
+      g_value_reset (&item);
+      break;
+    case GST_ITERATOR_RESYNC:
+      ...rollback changes to items...
+      gst_iterator_resync (it);
+      break;
+    case GST_ITERATOR_ERROR:
+      ...wrong parameters were given...
+      done = TRUE;
+      break;
+    case GST_ITERATOR_DONE:
+      done = TRUE;

+                       GObject *owner,
+                       GstIteratorItemFunction item);

+
Create a new iterator designed for iterating list
+.

+
The list you iterate is usually part of a data structure owner
+ and is
+protected with lock
+.

+
The iterator will use lock
+ to retrieve the next item of the list and it
+will then call the item
+ function before releasing lock
+ again.

+
When a concurrent update to the list is performed, usually by owner
+ while
+holding lock
+, master_cookie
+ will be updated. The iterator implementation
+will notice the update of the cookie and will return GST_ITERATOR_RESYNC to
+the user of the iterator in the next call to gst_iterator_next().

+

+
Parameters

+

+++++
+
+
+
+
+
+





it

+

+

+

+

+
gst_iterator_next ()

+
GstIteratorResult
+gst_iterator_next (GstIterator *it,
+                   GValue *elem);

+
Get the next item from the iterator in elem
+.

+
Only when this function returns GST_ITERATOR_OK, elem
+ will contain a valid
+value. elem
+ must have been initialized to the type of the iterator or
+initialized to zeroes with g_value_unset(). The caller is responsible for
+unsetting or resetting elem
+ with g_value_unset() or g_value_reset()
+after usage.

+
When this function returns GST_ITERATOR_DONE, no more elements can be
+retrieved from it
+.

+
A return value of GST_ITERATOR_RESYNC indicates that the element list was
+concurrently updated. The user of it
+ should call gst_iterator_resync() to
+get the newly updated list.

+
A return value of GST_ITERATOR_ERROR indicates an unrecoverable fatal error.

+                   gpointer user_data);

+
Folds func
+ over the elements of iter
+. That is to say, func
+ will be called
+as func
+ (object, ret
+, user_data
+) for each object in it
+. The normal use
+of this procedure is to accumulate the results of operating on the objects in
+ret
+.

+
This procedure can be used (and is used internally) to implement the
+gst_iterator_foreach() and gst_iterator_find_custom() operations.

+
The fold will proceed as long as func
+ returns TRUE. When the iterator has no
+more arguments, GST_ITERATOR_DONE will be returned. If func
+ returns FALSE,
+the fold will stop, and GST_ITERATOR_OK will be returned. Errors or resyncs
+will cause fold to return GST_ITERATOR_ERROR or GST_ITERATOR_RESYNC as
+appropriate.

+
The iterator will not be freed.

Description

+
The GstMeta structure should be included as the first member of a GstBuffer
+metadata structure. The structure defines the API of the metadata and should
+be accessible to all elements using the metadata.

+
A metadata API is registered with gst_meta_api_type_register() which takes a
+name for the metadata API and some tags associated with the metadata.
+With gst_meta_api_type_has_tag() one can check if a certain metadata API
+contains a given tag.

+
Multiple implementations of a metadata API can be registered.
+To implement a metadata API, gst_meta_register() should be used. This
+function takes all parameters needed to create, free and transform metadata
+along with the size of the metadata. The function returns a GstMetaInfo
+structure that contains the information for the implementation of the API.

+
A specific implementation can be retrieved by name with gst_meta_get_info().

+
See GstBuffer for how the metadata can be added, retrieved and removed from
+buffers.

+

+

+
Description

+
GstMiniObject is a simple structure that can be used to implement refcounted
+types.

+
Subclasses will include GstMiniObject as the first member in their structure
+and then call gst_mini_object_init() to initialize the GstMiniObject fields.

+
gst_mini_object_ref() and gst_mini_object_unref() increment and decrement the
+refcount respectively. When the refcount of a mini-object reaches 0, the
+dispose function is called first and when this returns TRUE, the free
+function of the miniobject is called.

+
A copy can be made with gst_mini_object_copy().

+
gst_mini_object_is_writable() will return TRUE when the refcount of the
+object is exactly 1, meaning the current caller has the only reference to the
+object. gst_mini_object_make_writable() will return a writable version of the
+object, which might be a new copy when the refcount was not 1.

+
Opaque data can be associated with a GstMiniObject with
+gst_mini_object_set_qdata() and gst_mini_object_get_qdata(). The data is
+meant to be specific to the particular object and is not automatically copied
+with gst_mini_object_copy() or similar methods.

+
A weak reference can be added and remove with gst_mini_object_weak_ref()
+and gst_mini_object_weak_unref() respectively.

+

+

+
Functions

+

+
GstMiniObjectCopyFunction ()

+
GstMiniObject *
+(*GstMiniObjectCopyFunction) (const GstMiniObject *obj);

+
Function prototype for methods to create copies of instances.

+

+
Parameters

+
+





obj

+

+
GstMiniObjectDisposeFunction ()

+
gboolean
+(*GstMiniObjectDisposeFunction) (GstMiniObject *obj);

+
Function prototype for when a miniobject has lost its last refcount.
+Implementation of the mini object are allowed to revive the
+passed object by doing a gst_mini_object_ref(). If the object is not
+revived after the dispose function, the function should return TRUE
+and the memory associated with the object is freed.

+

+
Parameters

+++++
+
+
+
+
+
+





obj

gst_mini_object_ref ()

+
GstMiniObject *
+gst_mini_object_ref (GstMiniObject *mini_object);

+
Increase the reference count of the mini-object.

Note that the refcount affects the writability
+of mini
+-object, see gst_mini_object_is_writable(). It is
+important to note that keeping additional references to
+GstMiniObject instances can potentially increase the number
+of memcpy operations in a pipeline, especially if the miniobject
+is a GstBuffer.

+
Adds a weak reference callback to a mini object. Weak references are
+used for notification when a mini object is finalized. They are called
+"weak references" because they allow you to safely hold a pointer
+to the mini object without calling gst_mini_object_ref()
+(gst_mini_object_ref() adds a strong reference, that is, forces the object
+to stay alive).

+

+
gst_mini_object_is_writable ()

+
gboolean
+gst_mini_object_is_writable (const GstMiniObject *mini_object);

+
If mini_object
+ has the LOCKABLE flag set, check if the current EXCLUSIVE
+lock on object
+ is the only one, this means that changes to the object will
+not be visible to any other object.

+
If the LOCKABLE flag is not set, check if the refcount of mini_object
+ is
+exactly 1, meaning that no other reference exists to the object and that the
+object is therefore writable.

+
Modification of a mini-object should only be done after verifying that it
+is writable.

+                           GDestroyNotify destroy);

+
This sets an opaque, named pointer on a miniobject.
+The name is specified through a GQuark (retrieved e.g. via
+g_quark_from_static_string()), and the pointer
+can be gotten back from the object
+ with gst_mini_object_get_qdata()
+until the object
+ is disposed.
+Setting a previously set user data pointer, overrides (frees)
+the old pointer set, using NULL as pointer essentially
+removes the data stored.

+
destroy
+ may be specified which is called with data
+ as argument
+when the object
+ is disposed, or the data is being overwritten by
+a call to gst_mini_object_set_qdata() with the same quark
+.

+
Modifies a pointer to point to a new mini-object. The modification
+is done atomically. This version is similar to gst_mini_object_replace()
+except that it does not increase the refcount of newdata
+ and thus
+takes ownership of newdata
+.

Description

+
These function allow to create a pipeline based on the syntax used in the
+gst-launch-1.0 utility (see man-page for syntax documentation).

+
Please note that these functions take several measures to create
+somewhat dynamic pipelines. Due to that such pipelines are not always
+reusable (set the state to NULL and back to PLAYING).

+

+

+
Functions

+

+
gst_parse_error_quark ()

+
GQuark
+gst_parse_error_quark (void);

+
Get the error quark used by the parsing subsystem.

+

+
Returns

+
 the quark of the parse errors.

+

+

+

+

+
gst_parse_launch ()

+
GstElement *
+gst_parse_launch (const gchar *pipeline_description,
+                  GError **error);

+
Create a new pipeline based on command line syntax.
+Please note that you might get a return value that is not NULL even though
+the error
+ is set. In this case there was a recoverable parsing error and you
+can try to play the pipeline.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





pipeline_description
the command line describing the pipeline
 
error
the error message in case of an erroneous pipeline.
 

+

+

+
Returns

+
a new element on success, NULL on
+failure. If more than one toplevel element is specified by the
+pipeline_description
+, all elements are put into a GstPipeline, which
+than is returned.

error
the error message in case of an erroneous pipeline.
 

+

+

+
Returns

+
a new element on success, NULL on
+failure. If more than one toplevel element is specified by the
+pipeline_description
+, all elements are put into a GstPipeline, which
+then is returned (unless the GST_PARSE_FLAG_PLACE_IN_BIN flag is set, in
+which case they are put in a GstBin instead).

+                                GError **err);

+
This is a convenience wrapper around gst_parse_launch() to create a
+GstBin from a gst-launch-style pipeline description. See
+gst_parse_launch() and the gst-launch man page for details about the
+syntax. Ghost pads on the bin for unlinked source or sink pads
+within the bin can automatically be created (but only a maximum of
+one ghost pad for each direction will be created; if you expect
+multiple unlinked source pads or multiple unlinked sink pads
+and want them all ghosted, you will have to create the ghost pads
+yourself).

 GstPoll
 GstPollFD
#defineGST_POLL_FD_INIT

+

+

+
Includes

+
#include <gst/gst.h>
+

+

+

+
Description

+
A GstPoll keeps track of file descriptors much like fd_set (used with
+select()) or a struct pollfd array (used with poll()). Once created with
+gst_poll_new(), the set can be used to wait for file descriptors to be
+readable and/or writable. It is possible to make this wait be controlled
+by specifying TRUE for the controllable
+ flag when creating the set (or
+later calling gst_poll_set_controllable()).

+
New file descriptors are added to the set using gst_poll_add_fd(), and
+removed using gst_poll_remove_fd(). Controlling which file descriptors
+should be waited for to become readable and/or writable are done using
+gst_poll_fd_ctl_read() and gst_poll_fd_ctl_write().

+
Use gst_poll_wait() to wait for the file descriptors to actually become
+readable and/or writable, or to timeout if no file descriptor is available
+in time. The wait can be controlled by calling gst_poll_restart() and
+gst_poll_set_flushing().

+
Once the file descriptor set has been waited for, one can use
+gst_poll_fd_has_closed() to see if the file descriptor has been closed,
+gst_poll_fd_has_error() to see if it has generated an error,
+gst_poll_fd_can_read() to see if it is possible to read from the file
+descriptor, and gst_poll_fd_can_write() to see if it is possible to
+write to it.

+

+

+
Functions

+

+
gst_poll_add_fd ()

gboolean
+gst_poll_add_fd (GstPoll *set,

gst_poll_fd_ignored ()

+
void
+gst_poll_fd_ignored (GstPoll *set,

+
Mark fd
+ as ignored so that the next call to gst_poll_wait() will yield

+gst_poll_new().

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





set
a GstPoll.
 
controllable
new controllable state.
 

+

+

+
Returns

+
 TRUE if the controllability of set
+could be updated.

+

+

+

+

+
gst_poll_set_flushing ()

+
void
+gst_poll_set_flushing (GstPoll *set,
+                       gboolean flushing);

+
When flushing
+ is TRUE, this function ensures that current and future calls
+to gst_poll_wait() will return -1, with errno set to EBUSY.

+
Unsetting the flushing state will restore normal operation of set
+.

+
This function only works for non-timer GstPoll objects created with
+gst_poll_new().

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





set
a GstPoll.
 
flushing
new flushing state.
 

+

+

+

+

+
gst_poll_wait ()

+
gint
+gst_poll_wait (GstPoll *set,
+               GstClockTime timeout);

+
Wait for activity on the file descriptors in set
+. This function waits up to
+the specified timeout
+.  A timeout of GST_CLOCK_TIME_NONE waits forever.

+
For GstPoll objects created with gst_poll_new(), this function can only be
+called from a single thread at a time.  If called from multiple threads,
+-1 will be returned with errno set to EPERM.

+
This is not true for timer GstPoll objects created with
+gst_poll_new_timer(), where it is allowed to have multiple threads waiting
+simultaneously.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





set
a GstPoll.
 
timeout
a timeout in nanoseconds.
 

+

+

+
Returns

+
 The number of GstPollFD in set
+that have activity or 0 when no
+activity was detected after timeout
+. If an error occurs, -1 is returned
+and errno is set.

+

+

+

+

+
gst_poll_read_control ()

+
gboolean
+gst_poll_read_control (GstPoll *set);

+
Read a byte from the control socket of the controllable set
+.

+
This function only works for timer GstPoll objects created with
+gst_poll_new_timer().

+

+
Parameters

+

+++++
+
+
+
+
+
+





set
a GstPoll.
 

+

+

+
Returns

+
 TRUE on success. FALSE when when there was no byte to read or
+reading the byte failed. If there was no byte to read, and only then, errno
+will contain EWOULDBLOCK or EAGAIN. For all other values of errno this always signals a
+critical error.

+

+

+

+

+
gst_poll_write_control ()

+
gboolean
+gst_poll_write_control (GstPoll *set);

+
Write a byte to the control socket of the controllable set
+.
+This function is mostly useful for timer GstPoll objects created with
+gst_poll_new_timer().

+
It will make any current and future gst_poll_wait() function return with
+1, meaning the control socket is set. After an equal amount of calls to
+gst_poll_read_control() have been performed, calls to gst_poll_wait() will
+block again until their timeout expired.

+
This function only works for timer GstPoll objects created with
+gst_poll_new_timer().

+

+
Parameters

+

+++++
+
+
+
+
+
+





set
a GstPoll.
 

+

+

+
Returns

+
 TRUE on success. FALSE when when the byte could not be written.
+errno contains the detailed error code but will never be EAGAIN, EINTR or
+EWOULDBLOCK. FALSE always signals a critical error.

+

+

+

+

+
Types and Values

+

+
GstPoll

+
typedef struct _GstPoll GstPoll;

+
A set of file/network descriptors.

+

+

+

+
GstPollFD

+
typedef struct {
+  int fd;
+} GstPollFD;
+

+
A file descriptor object.

+

+
Members

+

+++++
+
+
+
+
+
+





int fd;
a file descriptor
 

+

+

+

+

+
GST_POLL_FD_INIT

+
#define GST_POLL_FD_INIT  { -1, -1 }
+

+
A GstPollFD must be initialized with this macro, before it can be
+used. This macro can used be to initialize a variable, but it cannot
+be assigned to a variable. In that case you have to use
+gst_poll_fd_init().

+

+

+
Includes

+
#include <gst/gstprotection.h>
+

+

+

+
Description

+
The GstProtectionMeta class enables the information needed to decrypt a
+GstBuffer to be attached to that buffer.

+
Typically, a demuxer element would attach GstProtectionMeta objects
+to the buffers that it pushes downstream. The demuxer would parse the
+protection information for a video/audio frame from its input data and use
+this information to populate the GstStructure info
+ field,
+which is then encapsulated in a GstProtectionMeta object and attached to
+the corresponding output buffer using the gst_buffer_add_protection_meta()
+function. The information in this attached GstProtectionMeta would be
+used by a downstream decrypter element to recover the original unencrypted
+frame.

+

+

+
Functions

GstProtectionMeta *
+gst_buffer_add_protection_meta (GstBuffer *buffer,

Includes

+
#include <gst/gstprotection.h>
+

+

+

+
Description

+
A GstStream is a high-level object defining a stream of data which is, or
+can be, present in a GstPipeline.

+
It is defined by a unique identifier, a "Stream ID". A GstStream does not
+automatically imply the stream is present within a pipeline or element.

+
Any element that can introduce new streams in a pipeline should create the
+appropriate GstStream object, and can convey that object via the
+GST_EVENT_STREAM_START event and/or the GstStreamCollection.

+
Elements that do not modify the nature of the stream can add extra information
+on it (such as enrich the GstCaps, or GstTagList). This is typically done
+by parsing elements.

+

+

+

struct GstStream

+
struct GstStream {
+  const gchar *stream_id;
+};
+

+
A high-level object representing a single stream. It might be backed, or
+not, by an actual flow of data in a pipeline (GstPad).

+
A GstStream does not care about data changes (such as decoding, encoding,
+parsing,...) as long as the underlying data flow corresponds to the same
+high-level flow (ex: a certain audio track).

+
A GstStream contains all the information pertinent to a stream, such as
+stream-id, tags, caps, type, ...

+
Elements can subclass a GstStream for internal usage (to contain information
+pertinent to streams of data).

+

+

+

+

+

+

+
enum GstStreamType

+
GstStreamType describes a high level classification set for
+flows of data in GstStream objects.

+
Note that this is a flag, and therefore users should not assume it
+will be a single value. Do not use the equality operator for checking
+whether a stream is of a certain type.

A collection of GstStream that are available.

+
A GstStreamCollection will be provided by elements that can make those
+streams available. Applications can use the collection to show the user
+what streams are available by using gst_stream_collection_get_stream()

+
Once posted, a GstStreamCollection is immutable. Updates are made by sending
+a new GstStreamCollection message, which may or may not share some of
+the GstStream objects from the collection it replaces. The receiver can check
+the sender of a stream collection message to know which collection is
+obsoleted.

+
Several elements in a pipeline can provide GstStreamCollection.

+
Applications can activate streams from a collection by using the
+GST_EVENT_SELECT_STREAMS event on a pipeline, bin or element.

If you just want to retrieve the TOC in your application then all you
+need to do is watch for TOC messages on your pipeline's bus (or you can
+perform TOC query). This interface is only for setting TOC data, not for
+extracting it. To set TOC from the application, find proper tocsetter element
+and set TOC using gst_toc_setter_set_toc().

+
Elements implementing the GstTocSetter interface can extend existing TOC
+by getting extend UID for that (you can use gst_toc_find_entry() to retrieve it)
+with any TOC entries received from downstream.

+

+

+
Functions

+

+
gst_toc_setter_set_toc ()

+
void
+gst_toc_setter_set_toc (GstTocSetter *setter,
+                        GstToc *toc);

+
Set the given TOC on the setter. Previously set TOC will be
+unreffed before setting a new one.

+

+

+

+

+
Description

+
The following functions allow you to detect the media type of an unknown
+stream.

+

+

+
Functions

+

+
GstTypeFindFunction ()

+
void
+(*GstTypeFindFunction) (GstTypeFind *find,
+                        gpointer user_data);

+
A function that will be called by typefinding.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





find
A GstTypeFind structure
 
user_data
optional data to pass to the function
 

+

+

+

+

+
gst_type_find_peek ()

+
const guint8 *
+gst_type_find_peek (GstTypeFind *find,
+                    gint64 offset,
+                    guint size);

+
Returns the size
+ bytes of the stream to identify beginning at offset. If
+offset is a positive number, the offset is relative to the beginning of the
+stream, if offset is a negative number the offset is relative to the end of
+the stream. The returned memory is valid until the typefinding function
+returns and must not be freed.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+





find
The GstTypeFind object the function was called with
 
offset
The offset
 
size
The number of bytes to return
 

+

+

+
Returns

+
the
+requested data, or NULL if that data is not available. 

+
[transfer none][array length=size][nullable]

+

+

+

+

+
gst_type_find_suggest ()

+
void
+gst_type_find_suggest (GstTypeFind *find,
+                       guint probability,
+                       GstCaps *caps);

+
If a GstTypeFindFunction calls this function it suggests the caps with the
+given probability. A GstTypeFindFunction may supply different suggestions
+in one call.
+It is up to the caller of the GstTypeFindFunction to interpret these values.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+





find
The GstTypeFind object the function was called with
 
probability
The probability in percent that the suggestion is right
 
caps
The fixed GstCaps to suggest
 

+

+

+

+

+
gst_type_find_suggest_simple ()

+
void
+gst_type_find_suggest_simple (GstTypeFind *find,
+                              guint probability,
+                              const char *media_type,
+                              const char *fieldname,
+                              ...);

+
If a GstTypeFindFunction calls this function it suggests the caps with the
+given probability. A GstTypeFindFunction may supply different suggestions
+in one call. It is up to the caller of the GstTypeFindFunction to interpret
+these values.

+
This function is similar to gst_type_find_suggest(), only that instead of
+passing a GstCaps argument you can create the caps on the fly in the same
+way as you can with gst_caps_new_simple().

+
Make sure you terminate the list of arguments with a NULL argument and that
+the values passed have the correct type (in terms of width in bytes when
+passed to the vararg function - this applies particularly to gdouble and
+guint64 arguments).

+

+

+and "value" are splitted by "=" sub-delims. The "key" returned by this API may
+be undefined keyword by standard.
+A value may be NULL to indicate that the key should appear in the fragment
+string in the URI, but does not have a value. Free the returned GHashTable
+with g_hash_table_unref() when it is no longer required.

+

+

+
Description

+
The GstURIHandler is an interface that is implemented by Source and Sink
+GstElement to unify handling of URI.

+
An application can use the following functions to quickly get an element
+that handles the given URI for reading or writing
+(gst_element_make_from_uri()).

+
Source and Sink plugins should implement this interface when possible.

+

+

+
Functions

+

+
gst_uri_error_quark ()

+
GQuark
+gst_uri_error_quark (void);

+

+

+

+
GST_URI_TYPE_IS_VALID()

+
#define GST_URI_TYPE_IS_VALID(type) ((type) == GST_URI_SRC || (type) == GST_URI_SINK)
+

+
Tests if the type direction is valid.

+

+
Parameters

+

+++++
+
+
+
+
+
+





type
A GstURIType
 

+

+

+

+

+
gst_uri_protocol_is_valid ()

+
gboolean
+gst_uri_protocol_is_valid (const gchar *protocol);

+
Tests if the given string is a valid protocol identifier. Protocols
+must consist of alphanumeric characters, '+', '-' and '.' and must
+start with a alphabetic character. See RFC 3986 Section 3.1.

+

+
Parameters

+

+++++
+
+
+
+
+
+





protocol
A string
 

+

+

+
Returns

+
 TRUE if the string is a valid protocol identifier, FALSE otherwise.

+

+

+

+

+
gst_uri_protocol_is_supported ()

+
gboolean
+gst_uri_protocol_is_supported (const GstURIType type,
+                               const gchar *protocol);

+
Checks if an element exists that supports the given URI protocol. Note
+that a positive return value does not imply that a subsequent call to
+gst_element_make_from_uri() is guaranteed to work.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





type
Whether to check for a source or a sink

+

+
Returns

+
 TRUE

+

+

+

+

+
gst_uri_is_valid ()

+
gboolean
+gst_uri_is_valid (const gchar *uri);

+
Tests if the given string is a valid URI identifier. URIs start with a valid
+scheme followed by ":" and maybe a string identifying the location.

+

+
Parameters

+

+++++
+
+
+
+
+
+





uri
A URI string
 

+

+

+
Returns

+
 TRUE if the string is a valid URI

+

+

+

+
gst_uri_get_protocol ()

+
gchar *
+gst_uri_get_protocol (const gchar *uri);

+
+
+





uri
A URI string
 

+

+

+
Returns

[nullable]

+

+

+

+

+
gst_uri_get_location ()

+
gchar *
+gst_uri_get_location (const gchar *uri);

+
Extracts the location out of a given valid URI, ie. the protocol and "://"
+are stripped from the URI, which means that the location returned includes
+the hostname if one is specified. The returned string must be freed using
+g_free().

+
Free-function: g_free

+

+
Parameters

+

+++++
+
+
+
+
+
+





uri
A URI string
 

+

+

+
Returns

+
the location for this URI. Returns

+empty string is returned. 

+
[transfer full][nullable]

+

+

+

+

+
gst_uri_construct ()

+
gchar *
+gst_uri_construct (const gchar *protocol,
+                   const gchar *location);

gchar *
+gst_filename_to_uri (const gchar *filename,
+                     GError **error);

+
Similar to g_filename_to_uri(), but attempts to handle relative file paths
+as well. Before converting filename
+ into an URI, it will be prefixed by
+the current working directory if it is a relative path, and then the path
+will be canonicalised so that it doesn't contain any './' or '../' segments.

+
On Windows filename should be in UTF-8 encoding.

gst_util_seqnum_next ()

+
guint32
+gst_util_seqnum_next (void);

+
Return a constantly incrementing sequence number.

+
This function is used internally to GStreamer to be able to determine which
+events and messages are "the same". For example, elements may set the seqnum
+on a segment-done message to be the same as that of the last seek event, to
+indicate that event and the message correspond to the same segment.

+
This function never returns GST_SEQNUM_INVALID (which is 0).

+

+
Returns

+
 A constantly incrementing 32-bit unsigned integer, which might
+overflow at some point. Use gst_util_seqnum_compare() to make sure
+you handle wraparound correctly.

+
Searches inside array
+ for search_data
+ by using the comparison function
+search_func
+. array
+ must be sorted ascending.

As search_data
+ is always passed as second argument to search_func
+ it's
+not required that search_data
+ has the same type as the array elements.

+
The complexity of this search function is O(log (num_elements)).

+combination and order of values. Each value on its own is not particularly
+meaningful, only the ordered array in its entirety is meaningful. This is
+used for example to express channel layouts for multichannel audio where
+each channel needs to be mapped to a position in the room.

+

+

+
Description

+
Use the GST_VERSION_* macros e.g. when defining own plugins. The GStreamer
+runtime checks if these plugin and core version match and refuses to use a
+plugin compiled against a different version of GStreamer.
+You can also use the macros to keep the GStreamer version information in
+your application.

+
Use the gst_version() function if you want to know which version of
+GStreamer you are currently linked against.

+
The version macros get defined by including "gst/gst.h".

+

+

+
Functions

+

+
GST_CHECK_VERSION()

+
#define             GST_CHECK_VERSION(major,minor,micro)

+
Check whether a GStreamer version equal to or greater than
+major.minor.micro is present.

+GStreamer is a streaming media framework.
+It uses graphs of elements which operate on data.
+The functionality to process media is provided by plug-ins which provide
+features like elements, typefinding, and so on.
+This allows new functionality to be added simply by installing new plug-ins.
+    

+

+GStreamer is cross-platform and works on most UNIX-like platforms as well as
+Windows.  It is released under the GNU Library General Public License
+(GNU LGPL).

+
+How to run and debug your GStreamer application
+
+
+
+
+Running and debugging GStreamer Applications
+
+
+Environment variables
+
+ 
+GStreamer inspects a few of environment variables in addition to standard
+variables like LANG, PATH or HOME. 
+
+
+
+  <envar>GST_PLUGIN_SYSTEM_PATH</envar>,
+         <envar>GST_PLUGIN_SYSTEM_PATH_1_0</envar>
+
+  
+
+This environment variable can be set to a colon-separated list of paths (or
+semicolon-separated list on Windows).
+If this variable is not set, GStreamer will fill in this list for you
+with
+
+  
+    
+plug-ins in the user's home directory, or rather the user's "data home"
+directory according to the xdg base dir specification. Usually this will be
+a directory called
+plugins inside the
+.local/share/gstreamer-&GST_API_VERSION; directory in
+the user's home directory by default, though this search path may change if
+the XDG_DATA_HOME environment variable is set.
+    
+  
+  
+    
+plug-ins installed system-wide.  On this system, they are stored in
+&GST_PLUGINS_DIR;.
+    
+
+
+
+   
+
+    
+GStreamer will scan these paths for GStreamer plug-ins.  These plug-ins will
+be loaded after the plug-ins in the GST_PLUGIN_PATH variable below.
+
+The paths are scanned in the given order.  This allows a user to override
+system-installed plug-ins with his own versions.
+   
+  
+The GST_PLUGIN_SYSTEM_PATH_1_0 variant is useful if both the old GStreamer 0.10
+version and the new GStreamer 1.0 version need to be pointed to new plugin
+paths. The latter will use the _1_0 variant over the non-versioned one if
+it is set.
+  
+
+    
+Setting this variable to an empty string will cause GStreamer not to scan any
+system paths at all for plug-ins.  This can be useful if you're running
+uninstalled (for development purposes) or while running testsuites.
+   
+
+
+
+
+  <envar>GST_PLUGIN_PATH</envar>, <envar>GST_PLUGIN_PATH_1_0</envar>
+
+  
+This environment variable can be set to a colon-separated list of paths (or a
+semicolon-separated list on Windows).
+GStreamer will scan these paths for GStreamer plug-ins.  These plug-ins will
+be loaded in addition to, and before, the plug-ins in the system paths.
+  
+  
+The GST_PLUGIN_PATH_1_0 variant is useful if both the old GStreamer 0.10
+version and the new GStreamer 1.0 version need to be pointed to new plugin
+paths. The latter will use the _1_0 variant over the non-versioned one if
+it is set.
+  
+
+
+
+  <envar>GST_DEBUG</envar>
+
+  
+If GStreamer has been configured with ,
+this variable can be set to a list of debug options, which cause GStreamer
+to print out different types of debugging information to stderr.
+  
+  
+The variable takes a comma-separated list of "category_name:level" pairs
+to set specific levels for the individual categories.
+The level value ranges from 0 (nothing) to 9 (MEMDUMP).
+    
+
+      
+        1 - 
+        
+
+Logs all fatal errors.  These are errors that do not allow the core or elements
+to perform the requested action.  The application can still recover if
+programmed to handle the conditions that triggered the error.
+
+        
+      
+
+      
+        2 - 
+        
+
+Logs all warnings.  Typically these are non-fatal, but user-visible problems
+are expected to happen.
+
+        
+      
+
+      
+        3 - 
+        
+
+Logs all fixme messages. Fixme messages are messages that indicate that something
+in the executed code path is not fully implemented or handled yet.  The purpose
+of this message is to make it easier to spot incomplete/unfinished pieces of
+code when reading the debug log.
+
+        
+      
+
+      
+        4 - 
+        
+
+Logs all informational messages.  These are typically used for events in
+the system that only happen once, or are important and rare enough to be
+logged at this level.
+
+        
+      
+
+      
+        5 - 
+        
+
+Logs all debug messages.  These are general debug messages for events
+that happen only a limited number of times during an object's lifetime;
+these include setup, teardown, change of parameters, ...
+
+        
+      
+
+      
+        6 - 
+        
+
+Logs all log messages.  These are messages for events
+that happen repeatedly during an object's lifetime;
+these include streaming and steady-state conditions.
+
+        
+      
+
+      
+        7 - 
+        
+
+Logs all trace messages.  These messages for events
+that happen repeatedly during an object's lifetime such as the
+ref/unref cycles.
+
+        
+      
+
+      
+        9 - 
+        
+
+Log all memory dump messages. Memory dump messages are used to log
+(small) chunks of data as memory dumps in the log. They will be displayed
+as hexdump with ASCII characters.
+
+        
+      
+    
+
+ The category_name can contain " as a wildcard.
+  
+
+  
+For example, setting GST_DEBUG to
+, will cause the
+ category to be logged at full
+ level, while all categories starting with
+ will be logged at  level.
+  
+
+  
+To get all possible debug output, set
+GST_DEBUG
+to . For debugging purposes a  debug
+log is usually the most useful, as it contains all important information, but
+hides a lot of noise such as refs/unrefs. For bug reporting purposes, a
+ log is also what will be requested usually. It's often
+also worth running with  to see if there are any
+non-fatal errors or warnings that might be related to the problem at hand.
+  
+
+  
+Since GStreamer 1.2 it is also possible to specify debug levels by name,
+e.g. GST_DEBUG=*:WARNING,*audio*:LOG
+  
+
+
+
+
+  <envar>GST_DEBUG_NO_COLOR</envar>
+
+  
+Set this environment variable to any value ("1" typically) to switch off
+colouring in GST_DEBUG output. This has the same effect as specifying the
+ or
+=off command line option to
+well-behaved GStreamer applications (ie. those that pass command-line
+options correctly to GStreamer).
+This is particularly useful to reduce the size of debug output and also allows
+for the output to be compressed much better than with colours turned on.
+  
+  
+Has the same effect as setting GST_DEBUG_COLOR_MODE environment variable to
+"off".
+  
+
+
+
+
+  <envar>GST_DEBUG_COLOR_MODE</envar>
+
+  
+Set this environment variable to change log colouring in GST_DEBUG output.
+Possible values:
+    
+
+      
+        
+        
+          
+Enables debug log output coloring. Uses default coloring method for current
+platform. This is the default.
+          
+        
+      
+
+      
+        
+        
+          
+Disables debug log output coloring. This has the same effect as specifying the
+=off command line option to
+well-behaved GStreamer applications (ie. those that pass command-line
+options correctly to GStreamer).
+This is particularly useful to reduce the size of debug output and also allows
+for the output to be compressed much better than with colours turned on.
+          
+          
+Has the same effect as setting GST_DEBUG_NO_COLOR environment variable to
+any value.
+          
+        
+      
+
+      
+        
+        
+          
+Same as .
+          
+        
+      
+
+      
+        
+        
+          
+Same as .
+          
+        
+      
+
+      
+        
+        
+          
+Enables debug log output coloring and forces the use of UNIX termial codes
+for coloring, even if this method is not normally used on current platform.
+This has the same effect as specifying the
+=unix command line option to
+well-behaved GStreamer applications (ie. those that pass command-line options
+correctly to GStreamer).
+This is particularly useful to dump debug output into a file on non-UNIX
+platforms to be sent to developers who have viewers that support UNIX terminal
+codes.
+          
+        
+      
+
+    
+  
+
+
+
+
+  <envar>GST_DEBUG_OPTIONS</envar>
+
+  
+This environment variable can be used to tweak the behaviour of the debugging
+system. Currently the only options supported are "pretty-tags" and "full-tags".
+In "pretty-tags" mode (the default), taglists in the debug log will be
+serialized so that only the first few and last few bytes of a buffer-type tag
+will be serialized into the log, to avoid dumping hundreds of lines of useless
+output into the log in case of large image tags and the like.
+  
+
+
+
+
+  <envar>GST_DEBUG_DUMP_DOT_DIR</envar>
+
+  
+Set this environment variable to a path to turn on all
+#GST_DEBUG_BIN_TO_DOT_FILE or #GST_DEBUG_BIN_TO_DOT_FILE_WITH_TS calls
+and have the dot files in that location.
+  
+  
+This will only work if the application in question makes these calls in
+strategic places (like when the pipeline state changes or an error occurs).
+gst-launch-&GST_API_VERSION; is one such application.
+  
+  
+When gst-launch-&GST_API_VERSION; changes state through NULL to PLAYING
+and back to NULL, a dot file is generated on each state change. To have
+gst-launch-&GST_API_VERSION; write a snapshot of the pipeline state, send
+a SIGHUP to the gst-launch-&GST_API_VERSION; process.
+  
+  
+These .dot files can then be turned into images using the 'dot' utility
+from the graphviz set of tools, like this:
+  dot foo.dot -Tsvg -o foo.svg or
+  dot foo.dot -Tpng -o foo.png or
+  dot foo.dot -Tjpg -o foo.jpg.
+  
+  
+There is also a utility called xdot which allows you to
+view the dot file directly without converting it first.
+  
+
+
+
+
+
+  <envar>GST_REGISTRY</envar>, <envar>GST_REGISTRY_1_0</envar>
+
+  
+Set this environment variable to make GStreamer use a different file for the
+plugin cache / registry than the default one. This is useful when operating
+in a separate environment which should not affect the default cache in the
+user's home directory.
+  
+
+
+
+
+  <envar>GST_REGISTRY_FORK</envar>
+
+  
+Set this environment variable to "no" to prevent GStreamer from forking on
+startup in order to update the plugin registry. This is useful for debugging
+purposes, but should not be used under normal circumstances, since it means
+that plugins may be loaded into memory even if they are not needed by the
+application.
+  
+
+
+
+
+  <envar>GST_REGISTRY_UPDATE</envar>
+
+  
+Set this environment variable to "no" to prevent GStreamer from updating the
+plugin registry. This is useful for embedded device which is not updating the
+plugins frequently, it will save time when doing gst_init().
+  
+
+
+
+
+  <envar>GST_TRACE</envar>
+
+  
+    Enable memory allocation tracing. Most GStreamer objects have support for
+    tracing the number of unfreed objects and their memory pointers.
+  
+  
+The variable takes a comma-separated list of tracing options to enable.
+    
+
+      
+        live
+        
+
+  Counts all live objects and dumps an overview of the number of unfreed
+  objects at program exit.
+
+        
+      
+
+      
+        mem-live
+        
+
+  Keep track of the unfreed memory pointers and dump an overview of all unfreed
+  memory at program exit. Together with a level 9 debug log this can be used to
+  follow the lifecycle of leaked objects in order to track down where they are
+  leaked. This can be useful for debugging memory leaks in situations where
+  tools such as valgrind are not available, or not an option.
+
+        
+      
+    
+
+ Use  to enable all tracing flags.
+  
+
+
+
+  <envar>GST_DEBUG_FILE</envar>
+
+  
+  Set this variable to a file path to redirect all GStreamer debug
+  messages to this file. If left unset, debug messages with be output
+  unto the standard error.
+  
+
+
+
+
+  <envar>ORC_CODE</envar>
+
+  
+Useful Orc environment variable. Set ORC_CODE=debug to enable debuggers
+such as gdb to create useful backtraces from Orc-generated code.  Set
+ORC_CODE=backup or ORC_CODE=emulate if you suspect Orc's SIMD code
+generator is producing incorrect code (Quite a few important
+GStreamer plugins like videotestsrc, audioconvert or audioresample use Orc).
+One can also combine flags like ORC_CODE=backup,debug.
+  
+
+
+
+
+  <envar>G_DEBUG</envar>
+
+  
+Useful GLib environment variable. Set G_DEBUG=fatal_warnings to make
+GStreamer programs abort when a critical warning such as an assertion failure
+occurs. This is useful if you want to find out which part of the code caused
+that warning to be triggered and under what circumstances. Simply set G_DEBUG
+as mentioned above and run the program in gdb (or let it core dump). Then get
+a stack trace in the usual way.
+  
+
+
+
+
+  <envar>G_SLICE</envar>
+
+  
+Useful GLib environment variable. Set G_SLICE=always-malloc when running
+GStreamer programs in valgrind, or debugging memory leaks with other tools.
+See the GLib API reference for more details.
+  
+
+
+
+
+  <envar>GST_TAG_ENCODING</envar>
+  
+Try this character encoding first for tag-related strings where the encoding
+is not defined and which are not UTF-8 already. By default the current locale
+will be tried (if not UTF-8).
+  
+
+
+
+  <envar>GST_TAG_ID3_ENCODING</envar>
+  
+Try this character encoding first for ID3 tag-related strings where the
+encoding is not defined and which are not UTF-8 already. By default the current
+locale will be tried (if not UTF-8).
+  
+
+
+
+  <envar>GST_TAG_ID3V1_ENCODING</envar>
+  
+Try this character encoding first for ID3v1 tag-related strings where the
+encoding does not look like UTF-8.
+  
+
+
+
+  <envar>GST_GL_WINDOW</envar>
+  
+Influences the window system to use by the GStreamer OpenGL library.
+Common values are 'x11', 'wayland', 'win32' or 'cocoa'.
+  
+
+
+
+  <envar>GST_GL_PLATFORM</envar>
+  
+Influences the OpenGL platform to use by the GStreamer OpenGL library.
+Common values are 'egl', 'glx', 'wgl' or 'cgl'.
+  
+
+
+
+  <envar>GST_GL_API</envar>
+  
+Influences the OpenGL API requested by the OpenGL platform.
+Common values are 'opengl' or 'gles2'.

+    GStreamer Libraries
+
+    
+      To ease the creation of plugins, a library system was created. The most common
+      functions for a plugin can be found in a library.
+    
+    
+      GStreamer provides some standard libraries you can use to create plugins.
+    
+
+    
+      GStreamer Base and Utillity Classes
+      
+        libgstbase-&GST_API_VERSION;.so provides some base classes to be extended
+        by elements and utillity classes that are most useful for plugin developers.

+
+    
+      GStreamer Dynamic Parameter Control
+      
+        libgstcontroller-&GST_API_VERSION;.so provides functionality to animate
+        element properties over time.

Description

+
This class is for elements that receive buffers in an undesired size.
+While for example raw video contains one image per buffer, the same is not
+true for a lot of other formats, especially those that come directly from
+a file. So if you have undefined buffer sizes and require a specific size,
+this object is for you.

+
An adapter is created with gst_adapter_new(). It can be freed again with
+g_object_unref().

+
The theory of operation is like this: All buffers received are put
+into the adapter using gst_adapter_push() and the data is then read back
+in chunks of the desired size using gst_adapter_map()/gst_adapter_unmap()
+and/or gst_adapter_copy(). After the data has been processed, it is freed
+using gst_adapter_unmap().

+
Other methods such as gst_adapter_take() and gst_adapter_take_buffer()
+combine gst_adapter_map() and gst_adapter_unmap() in one method and are
+potentially more convenient for some use cases.

+
For example, a sink pad's chain function that needs to pass data to a library
+in 512-byte chunks could be implemented like this:

+

+  
+    
+      
+

+sink_pad_chain (GstPad *pad, GstObject *parent, GstBuffer *buffer)
+{
+  MyElement *this;
+  GstAdapter *adapter;
+  GstFlowReturn ret = GST_FLOW_OK;
+
+  this = MY_ELEMENT (parent);
+
+  adapter = this->adapter;
+
+  // put buffer into adapter
+  gst_adapter_push (adapter, buffer);
+
+  // while we can read out 512 bytes, process them
+  while (gst_adapter_available (adapter) >= 512 && ret == GST_FLOW_OK) {
+    const guint8 *data = gst_adapter_map (adapter, 512);
+    // use flowreturn as an error value
+    ret = my_library_foo (data);
+    gst_adapter_unmap (adapter);
+    gst_adapter_flush (adapter, 512);
+  }
+  return ret;
+}

+

+
+

+
For another example, a simple element inside GStreamer that uses GstAdapter
+is the libvisual element.

+
An element using GstAdapter in its sink pad chain function should ensure that
+when the FLUSH_STOP event is received, that any queued data is cleared using
+gst_adapter_clear(). Data should also be cleared or processed on EOS and
+when changing state from GST_STATE_PAUSED to GST_STATE_READY.

+
Also check the GST_BUFFER_FLAG_DISCONT flag on the buffer. Some elements might
+need to clear the adapter after a discontinuity.

+
The adapter will keep track of the timestamps of the buffers
+that were pushed. The last seen timestamp before the current position
+can be queried with gst_adapter_prev_pts(). This function can
+optionally return the number of bytes between the start of the buffer that
+carried the timestamp and the current adapter position. The distance is
+useful when dealing with, for example, raw audio samples because it allows
+you to calculate the timestamp of the current adapter position by using the
+last seen timestamp and the amount of bytes since.  Additionally, the
+gst_adapter_prev_pts_at_offset() can be used to determine the last
+seen timestamp at a particular offset in the adapter.

+
The adapter will also keep track of the offset of the buffers
+(GST_BUFFER_OFFSET) that were pushed. The last seen offset before the
+current position can be queried with gst_adapter_prev_offset(). This function
+can optionally return the number of bytes between the start of the buffer
+that carried the offset and the current adapter position.

+
Additionally the adapter also keeps track of the PTS, DTS and buffer offset
+at the last discontinuity, which can be retrieved with
+gst_adapter_pts_at_discont(), gst_adapter_dts_at_discont() and
+gst_adapter_offset_at_discont(). The number of bytes that were consumed
+since then can be queried with gst_adapter_distance_from_discont().

+
A last thing to note is that while GstAdapter is pretty optimized,
+merging buffers still might be an operation that requires a malloc() and
+memcpy() operation, and these operations are not the fastest. Because of
+this, some functions like gst_adapter_available_fast() are provided to help
+speed up such cases should you want to. To avoid repeated memory allocations,
+gst_adapter_copy() can be used to copy data into a (statically allocated)
+user provided buffer.

+
GstAdapter is not MT safe. All operations on an adapter must be serialized by
+the caller. This is not normally a problem, however, as the normal use case
+of GstAdapter is inside one pad's chain function, in which case access is
+serialized via the pad's STREAM_LOCK.

+
Note that gst_adapter_push() takes ownership of the buffer passed. Use
+gst_buffer_ref() before pushing it into the adapter if you still want to
+access the buffer later. The adapter will never modify the data in the
+buffer pushed in it.

+

+

+
Functions

+

+
gst_adapter_new ()

+
GstAdapter *
+gst_adapter_new (void);

+
Creates a new GstAdapter. Free with g_object_unref().

+

+
Returns

+
a new GstAdapter. 

+
[transfer full]

+

+

+

+

+
gst_adapter_clear ()

+
void
+gst_adapter_clear (GstAdapter *adapter);

+
Removes all buffers from adapter
+.

+

+
Parameters

+

+++++
+
+
+
+
+
+





adapter
a GstAdapter
 

+

+

+

+

+
gst_adapter_push ()

+
void
+gst_adapter_push (GstAdapter *adapter,
+                  GstBuffer *buf);

+
Adds the data from buf
+ to the data stored inside adapter
+ and takes
+ownership of the buffer.

+

+
Parameters

+

+++++
+
+
+
+
+
+

+
+
+
+
+
+





adapter
a GstAdapter
 
buf
a GstBuffer to add to queue in the adapter. 
[transfer full]

+

+

+

+

+
gst_adapter_map ()

+
gconstpointer
+gst_adapter_map (GstAdapter *adapter,
+                 gsize size);

+
Gets the first size
+ bytes stored in the adapter
+. The returned pointer is
+valid until the next function is called on the adapter.

+
Note that setting the returned pointer as the data of a GstBuffer is
+incorrect for general-purpose plugins. The reason is that if a downstream
+element stores the buffer so that it has access to it outside of the bounds
+of its chain function, the buffer will have an invalid data pointer after
+your element flushes the bytes. In that case you should use
+gst_adapter_take(), which returns a freshly-allocated buffer that you can set
+as GstBuffer memory or the potentially more performant
+gst_adapter_take_buffer().

+
Returns NULL if size
+ bytes are not available.

+

+

+                  gsize size);

+
Copies size
+ bytes of data starting at offset
+ out of the buffers
+contained in GstAdapter into an array dest

+
Similar to gst_adapter_copy, but more suitable for language bindings. size
+
+bytes of data starting at offset
+ will be copied out of the buffers contained
+in adapter
+ and into a new GBytes structure which is returned. Depending on
+the value of the size
+ argument an empty GBytes structure may be returned.

gst_adapter_take_buffer ()

+
GstBuffer *
+gst_adapter_take_buffer (GstAdapter *adapter,
+                         gsize nbytes);

+
Returns a GstBuffer containing the first nbytes
+ bytes of the
+adapter
+. The returned bytes will be flushed from the adapter.
+This function is potentially more performant than
+gst_adapter_take() since it can reuse the memory in pushed buffers
+by subbuffering or merging. This function will always return a
+buffer with a single memory region.

+
Note that no assumptions should be made as to whether certain buffer
+flags such as the DISCONT flag are set on the returned buffer, or not.
+The caller needs to explicitly set or unset flags that should be set or
+unset.

+
Since 1.6 this will also copy over all GstMeta of the input buffers except
+for meta with the GST_META_FLAG_POOLED flag or with the "memory" tag.

+
Caller owns a reference to the returned buffer. gst_buffer_unref() after
+usage.

GstBuffer *
+gst_adapter_take_buffer_fast (GstAdapter *adapter,

+
Returns a GstBuffer containing the first nbytes
+ of the adapter
+.
+The returned bytes will be flushed from the adapter.  This function
+is potentially more performant than gst_adapter_take_buffer() since
+it can reuse the memory in pushed buffers by subbuffering or
+merging. Unlike gst_adapter_take_buffer(), the returned buffer may
+be composed of multiple non-contiguous GstMemory objects, no
+copies are made.

+
Note that no assumptions should be made as to whether certain buffer
+flags such as the DISCONT flag are set on the returned buffer, or not.
+The caller needs to explicitly set or unset flags that should be set or
+unset.

+
This will also copy over all GstMeta of the input buffers except
+for meta with the GST_META_FLAG_POOLED flag or with the "memory" tag.

+
This function can return buffer up to the return value of
+gst_adapter_available() without making copies if possible.

+
Caller owns a reference to the returned buffer. gst_buffer_unref() after
+usage.

Returns a GstBufferList of buffers containing the first nbytes
+ bytes of
+the adapter
+. The returned bytes will be flushed from the adapter.
+When the caller can deal with individual buffers, this function is more
+performant because no memory should be copied.

+
Caller owns the returned list. Call gst_buffer_list_unref() to free
+the list after usage.

+
Description

+
Manages a set of pads with the purpose of aggregating their buffers.
+Control is given to the subclass when all pads have data.

+
    
+
  • Base class for mixers and muxers. Subclasses should at least implement
+the GstAggregatorClass.aggregate() virtual method.
    • 
+
  • Installs a GstPadChainFunction, a GstPadEventFullFunction and a
+GstPadQueryFunction to queue all serialized data packets per sink pad.
+Subclasses should not overwrite those, but instead implement
+GstAggregatorClass.sink_event() and GstAggregatorClass.sink_query() as
+needed.
    • 
+
  • When data is queued on all pads, the aggregate vmethod is called.
    • 
+
  • One can peek at the data on any given GstAggregatorPad with the
+gst_aggregator_pad_peek_buffer() method, and remove it from the pad
+with the gst_aggregator_pad_pop_buffer() method. When a buffer
+has been taken with pop_buffer(), a new buffer can be queued
+on that pad.
    • 
+
  • If the subclass wishes to push a buffer downstream in its aggregate
+implementation, it should do so through the
+gst_aggregator_finish_buffer() method. This method will take care
+of sending and ordering mandatory events such as stream start, caps
+and segment.
    • 
+
  • Same goes for EOS events, which should not be pushed directly by the
+subclass, it should instead return GST_FLOW_EOS in its aggregate
+implementation.
    • 
+
  • Note that the aggregator logic regarding gap event handling is to turn
+these into gap buffers with matching PTS and duration. It will also
+flag these buffers with GST_BUFFER_FLAG_GAP and GST_BUFFER_FLAG_DROPPABLE
+to ease their identification and subsequent processing.
    • 
+
  • Subclasses must use (a subclass of) GstAggregatorPad for both their
+sink and source pads.
+See gst_element_class_add_static_pad_template_with_gtype().
    • 
+

+
This class used to live in gst-plugins-bad and was moved to core.

The aggregator base class will handle in a thread-safe way all manners of
+concurrent flushes, seeks, pad additions and removals, leaving to the
+subclass the responsibility of clipping buffers, and aggregating buffers in
+the way the implementor sees fit.

+
It will also take care of event ordering (stream-start, segment, eos).

+
Basically, a simple implementation will override aggregate
+, and call
+_finish_buffer from inside that function.

flush ()
Optional.
+Called after a successful flushing seek, once all the flush
+stops have been received. Flush pad-specific data in
+GstAggregatorPad->flush.
 
clip ()
Optional.
+Called when a buffer is received on a sink pad, the task of
+clipping it and translating it to the current segment falls
+on the subclass. The function should use the segment of data
+and the negotiated media type on the pad to perform
+clipping of input buffer. This function takes ownership of
+buf and should output a buffer or return NULL in
+if the buffer should be dropped.
 
finish_buffer ()
Optional.
+Called when a subclass calls gst_aggregator_finish_buffer()
+from their aggregate function to push out a buffer.
+Subclasses can override this to modify or decorate buffers
+before they get pushed out. This function takes ownership
+of the buffer passed. Subclasses that override this method
+should always chain up to the parent class virtual method.
 
sink_event ()
Optional.
+Called when an event is received on a sink pad, the subclass
+should always chain up.
 
sink_query ()
Optional.
+Called when a query is received on a sink pad, the subclass
+should always chain up.
 
src_event ()
Optional.
+Called when an event is received on the src pad, the subclass
+should always chain up.
 
src_query ()
Optional.
+Called when a query is received on the src pad, the subclass
+should always chain up.
 
src_activate ()
Optional.
+Called when the src pad is activated, it will start/stop its
+pad task right after that call.
 
aggregate ()
Mandatory.
+Called when buffers are queued on all sinkpads. Classes
+should iterate the GstElement->sinkpads and peek or steal
+buffers from the GstAggregatorPads. If the subclass returns
+GST_FLOW_EOS, sending of the eos event will be taken care
+of. Once / if a buffer has been constructed from the
+aggregated buffers, the subclass should call _finish_buffer.
 
stop ()
Optional.
+Called when the element goes from PAUSED to READY.
+The subclass should free all resources and reset its state.
 
start ()
Optional.
+Called when the element goes from READY to PAUSED.
+The subclass should get ready to process
+aggregated buffers.
 
get_next_time ()
Optional.
+Called when the element needs to know the running time of the next
+rendered buffer for live pipelines. This causes deadline
+based aggregation to occur. Defaults to returning
+GST_CLOCK_TIME_NONE causing the element to wait for buffers
+on all sink pads before aggregating.
 
create_new_pad ()
  
update_src_caps ()
Lets subclasses update the GstCaps representing
+the src pad caps before usage.  The result should end up
+in ret
+. Return GST_AGGREGATOR_FLOW_NEED_DATA to indicate that the
+element needs more information (caps, a buffer, etc) to
+choose the correct caps. Should return ANY caps if the
+stream has not caps at all.
 
fixate_src_caps ()
Optional.
+Fixate and return the src pad caps provided.  The function takes
+ownership of caps
+and returns a fixated version of
+caps
+. caps
+is not guaranteed to be writable.
 
negotiated_src_caps ()
Optional.
+Notifies subclasses what caps format has been negotiated
 
decide_allocation ()
Optional.
+Allows the subclass to influence the allocation choices.
+Setup the allocation parameters for allocating output
+buffers. The passed in query contains the result of the
+downstream allocation query.
 
propose_allocation ()

Description

+
This base class is for parser elements that process data and splits it
+into separate audio/video/whatever frames.

+
It provides for:

+
    
+
  • provides one sink pad and one source pad
    • 
+
  • handles state changes
    • 
+
  • can operate in pull mode or push mode
    • 
+
  • handles seeking in both modes
    • 
+
  • handles events (SEGMENT/EOS/FLUSH)
    • 
+
  • handles queries (POSITION/DURATION/SEEKING/FORMAT/CONVERT)
    • 
+
  • handles flushing
    • 
+

+
The purpose of this base class is to provide the basic functionality of
+a parser and share a lot of rather complex code.

+

+
Description of the parsing mechanism:

+

+
Set-up phase

+
    
+
  • GstBaseParse calls start
+ to inform subclass that data processing is
+about to start now.
    • 
+
  • GstBaseParse class calls set_sink_caps
+ to inform the subclass about
+incoming sinkpad caps. Subclass could already set the srcpad caps
+accordingly, but this might be delayed until calling
+gst_base_parse_finish_frame() with a non-queued frame.
    • 
+
  • At least at this point subclass needs to tell the GstBaseParse class
+how big data chunks it wants to receive (min_frame_size). It can do
+this with gst_base_parse_set_min_frame_size().
    • 
+
  • GstBaseParse class sets up appropriate data passing mode (pull/push)
+and starts to process the data.
    • 
+

+

+

+
Parsing phase

+
    
+
  • GstBaseParse gathers at least min_frame_size bytes of data either
+by pulling it from upstream or collecting buffers in an internal
+GstAdapter.
    • 
+
  • 
+
    A buffer of (at least) min_frame_size bytes is passed to subclass with
+handle_frame
+. Subclass checks the contents and can optionally
+return GST_FLOW_OK along with an amount of data to be skipped to find
+a valid frame (which will result in a subsequent DISCONT).
+If, otherwise, the buffer does not hold a complete frame,
+handle_frame
+ can merely return and will be called again when additional
+data is available.  In push mode this amounts to an
+additional input buffer (thus minimal additional latency), in pull mode
+this amounts to some arbitrary reasonable buffer size increase.
+Of course, gst_base_parse_set_min_frame_size() could also be used if a
+very specific known amount of additional data is required.
+If, however, the buffer holds a complete valid frame, it can pass
+the size of this frame to gst_base_parse_finish_frame().
+If acting as a converter, it can also merely indicate consumed input data
+while simultaneously providing custom output data.
+Note that baseclass performs some processing (such as tracking
+overall consumed data rate versus duration) for each finished frame,
+but other state is only updated upon each call to handle_frame
+
+(such as tracking upstream input timestamp).
    
+
    Subclass is also responsible for setting the buffer metadata
+(e.g. buffer timestamp and duration, or keyframe if applicable).
+(although the latter can also be done by GstBaseParse if it is
+appropriately configured, see below).  Frame is provided with
+timestamp derived from upstream (as much as generally possible),
+duration obtained from configuration (see below), and offset
+if meaningful (in pull mode).
    
+
    Note that check_valid_frame
+ might receive any small
+amount of input data when leftover data is being drained (e.g. at EOS).
    
+
    • 
+
  • As part of finish frame processing,
+just prior to actually pushing the buffer in question,
+it is passed to pre_push_frame
+ which gives subclass yet one
+last chance to examine buffer metadata, or to send some custom (tag)
+events, or to perform custom (segment) filtering.
    • 
+
  • During the parsing process GstBaseParseClass will handle both srcpad
+and sinkpad events. They will be passed to subclass if event
+ or
+src_event
+ callbacks have been provided.
    • 
+

+

+

+
Shutdown phase

+
  • GstBaseParse class calls stop
+ to inform the subclass that data
+parsing will be stopped.

+
Subclass is responsible for providing pad template caps for
+source and sink pads. The pads need to be named "sink" and "src". It also
+needs to set the fixed caps on srcpad, when the format is ensured (e.g.
+when base class calls subclass' set_sink_caps
+ function).

+
This base class uses GST_FORMAT_DEFAULT as a meaning of frames. So,
+subclass conversion routine needs to know that conversion from
+GST_FORMAT_TIME to GST_FORMAT_DEFAULT must return the
+frame number that can be found from the given byte position.

+
GstBaseParse uses subclasses conversion methods also for seeking (or
+otherwise uses its own default one, see also below).

+
Subclass start
+ and stop
+ functions will be called to inform the beginning
+and end of data processing.

+
Things that subclass need to take care of:

+
    
+
  • Provide pad templates
    • 
+
  • Fixate the source pad caps when appropriate
    • 
+
  • Inform base class how big data chunks should be retrieved. This is
+done with gst_base_parse_set_min_frame_size() function.
    • 
+
  • Examine data chunks passed to subclass with handle_frame
+ and pass
+proper frame(s) to gst_base_parse_finish_frame(), and setting src pad
+caps and timestamps on frame.
    • 
+
  • Provide conversion functions
    • 
+
  • Update the duration information with gst_base_parse_set_duration()
    • 
+
  • Optionally passthrough using gst_base_parse_set_passthrough()
    • 
+
  • Configure various baseparse parameters using
+gst_base_parse_set_average_bitrate(), gst_base_parse_set_syncable()
+and gst_base_parse_set_frame_rate().
    • 
+
  • In particular, if subclass is unable to determine a duration, but
+parsing (or specs) yields a frames per seconds rate, then this can be
+provided to GstBaseParse to enable it to cater for
+buffer time metadata (which will be taken from upstream as much as
+possible). Internally keeping track of frame durations and respective
+sizes that have been pushed provides GstBaseParse with an estimated
+bitrate. A default convert
+ (used if not overridden) will then use these
+rates to perform obvious conversions.  These rates are also used to
+update (estimated) duration at regular frame intervals.

gst_base_parse_merge_tags ()

+
void
+gst_base_parse_merge_tags (GstBaseParse *parse,
+                           GstTagList *tags,
+                           GstTagMergeMode mode);

+
Sets the parser subclass's tags and how they should be merged with any
+upstream stream tags. This will override any tags previously-set
+with gst_base_parse_merge_tags().

+
Note that this is provided for convenience, and the subclass is
+not required to use this and can still do tag handling on its own.

gst_base_parse_set_duration ()

+
void
+gst_base_parse_set_duration (GstBaseParse *parse,
+                             GstFormat fmt,
+                             gint64 duration,
+                             gint interval);

+
Sets the duration of the currently playing media. Subclass can use this
+when it is able to determine duration and/or notices a change in the media
+duration.  Alternatively, if interval
+ is non-zero (default), then stream
+duration is determined based on estimated bitrate, and updated every interval
+
+frames.

+

+
Parameters

+
+
+
+
+
+
+
+
+
+
+

parse
GstBaseParse.
 
fmt

gst_base_parse_set_average_bitrate ()

+
void
+gst_base_parse_set_average_bitrate (GstBaseParse *parse,
+                                    guint bitrate);

+
Optionally sets the average bitrate detected in media (if non-zero),
+e.g. based on metadata, as it will be posted to the application.

+
By default, announced average bitrate is estimated. The average bitrate
+is used to estimate the total duration of the stream and to estimate
+a seek position, if there's no index and the format is syncable
+(see gst_base_parse_set_syncable()).

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+

+                                   guint min_size);

+
Subclass can use this function to tell the base class that it needs to
+give at least min_size buffers.

+

+
Parameters

+
+
+
+
+
+
+
+

gst_base_parse_set_passthrough ()

+
void
+gst_base_parse_set_passthrough (GstBaseParse *parse,
+                                gboolean passthrough);

+
Set if the nature of the format or configuration does not allow (much)
+parsing, and the parser should operate in passthrough mode (which only
+applies when operating in push mode). That is, incoming buffers are
+pushed through unmodified, i.e. no check_valid_frame
+ or parse_frame
+
+callbacks will be invoked, but pre_push_frame
+ will still be invoked,
+so subclass can perform as much or as little is appropriate for
+passthrough semantics in pre_push_frame
+.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+

+                                    gboolean has_timing);

+
Set if frames carry timing information which the subclass can (generally)
+parse and provide.  In particular, intrinsic (rather than estimated) time
+can be obtained following a seek.

+

+
Parameters

+

+++++
+
+

gst_base_parse_drain ()

+
void
+gst_base_parse_drain (GstBaseParse *parse);

+
Drains the adapter until it is empty. It decreases the min_frame_size to
+match the current adapter size and calls chain method until the adapter
+is emptied or chain returns with error.

+                               guint lead_out);

+
If frames per second is configured, parser can take care of buffer duration
+and timestamping.  When performing segment clipping, or seeking to a specific
+location, a corresponding decoder might need an initial lead_in
+ and a
+following lead_out
+ number of frames to ensure the desired segment is
+entirely filled upon decoding.

+                            GstClockTime max_latency);

+
Sets the minimum and maximum (which may likely be equal) latency introduced
+by the parsing process.  If there is such a latency, which depends on the
+particular parsing of the format, it typically corresponds to 1 frame duration.

gst_base_parse_set_infer_ts ()

+
void
+gst_base_parse_set_infer_ts (GstBaseParse *parse,
+                             gboolean infer_ts);

+
By default, the base class might try to infer PTS from DTS and vice
+versa.  While this is generally correct for audio data, it may not
+be otherwise. Sub-classes implementing such formats should disable
+timestamp inferring.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+

gst_base_parse_set_pts_interpolation ()

+
void
+gst_base_parse_set_pts_interpolation (GstBaseParse *parse,
+                                      gboolean pts_interpolate);

+
By default, the base class will guess PTS timestamps using a simple
+interpolation (previous timestamp + duration), which is incorrect for
+data streams with reordering, where PTS can go backward. Sub-classes
+implementing such formats should disable PTS interpolation.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+

void
+gst_base_parse_set_ts_at_offset (GstBaseParse *parse,
+                                 gsize offset);

+
This function should only be called from a handle_frame
+ implementation.

+
GstBaseParse creates initial timestamps for frames by using the last
+timestamp seen in the stream before the frame starts.  In certain
+cases, the correct timestamps will occur in the stream after the
+start of the frame, but before the start of the actual picture data.
+This function can be used to set the timestamps based on the offset
+into the frame data that the picture starts.

+
Adds an entry to the index associating offset

+                          gint overhead);

+
Allocates a new GstBaseParseFrame. This function is mainly for bindings,

+++++
+
+
+
+
+
+
+
+
+
+
+

buffer
a GstBuffer. 
[transfer none]
flags
the flags
 
overhead
number of bytes in this frame which should be counted as

+Set to -1 to mark the entire frame as metadata. If in doubt, set to 0.
 

+

+

+
Returns

+
 a newly-allocated GstBaseParseFrame. Free with
+gst_base_parse_frame_free() when no longer needed.

+

+

+

+
gst_base_parse_frame_init ()

+
void
+gst_base_parse_frame_init (GstBaseParseFrame *frame);

+
Sets a GstBaseParseFrame to initial state.  Currently this means
+all public fields are zero-ed and a private flag is set to make
+sure gst_base_parse_frame_free() only frees the contents but not
+the actual frame. Use this function to initialise a GstBaseParseFrame
+allocated on the stack.

+

+
Parameters

+

GstFlowReturn
+gst_base_parse_push_frame (GstBaseParse *parse,
+                           GstBaseParseFrame *frame);

+
Pushes the frame's buffer downstream, sends any pending events and
+does some timestamp and segment handling. Takes ownership of
+frame's buffer, though caller retains ownership of frame
+.

+
This must be called with sinkpad STREAM_LOCK held.

+                             gint size);

+
Collects parsed data and pushes this downstream.
+Source pad caps must be set when this is called.

+
If frame
+'s out_buffer is set, that will be used as subsequent frame data.
+Otherwise, size
+ samples will be taken from the input and used for output,
+and the output's metadata (timestamps etc) will be taken as (optionally)
+set by the subclass on frame
+'s (input) buffer (which is otherwise
+ignored for any but the above purpose/information).

+
Note that the latter buffer is invalidated by this call, whereas the
+caller retains ownership of frame
+.

start ()
Optional.
+Called when the element starts processing.
+Allows opening external resources.
 
stop ()
Optional.
+Called when the element stops processing.
+Allows closing external resources.
 
set_sink_caps ()
Optional.
+Allows the subclass to be notified of the actual caps set.
 
handle_frame ()
Parses the input data into valid frames as defined by subclass
+which should be passed to gst_base_parse_finish_frame().
+The frame's input buffer is guaranteed writable,
+whereas the input frame ownership is held by caller
+(so subclass should make a copy if it needs to hang on).
+Input buffer (data) is provided by baseclass with as much
+metadata set as possible by baseclass according to upstream
+information and/or subclass settings,
+though subclass may still set buffer timestamp and duration
+if desired.
 
pre_push_frame ()
Optional.
+Called just prior to pushing a frame (after any pending
+events have been sent) to give subclass a chance to perform
+additional actions at this time (e.g. tag sending) or to
+decide whether this buffer should be dropped or not
+(e.g. custom segment clipping).
 
convert ()
Optional.
+Convert between formats.
 
sink_event ()
Optional.
+Event handler on the sink pad. This function should chain
+up to the parent implementation to let the default handler
+run.
 
src_event ()
Optional.
+Event handler on the source pad. Should chain up to the
+parent to let the default handler run.
 
get_sink_caps ()
Optional.
+Allows the subclass to do its own sink get caps if needed.
 
detect ()
Optional.
+Called until it doesn't return GST_FLOW_OK anymore for
+the first buffers. Can be used by the subclass to detect
+the stream format.
 
sink_query ()
Optional.
+Query handler on the sink pad. This function should chain
+up to the parent implementation to let the default handler
+run (Since 1.2)
 
src_query ()
Optional.
+Query handler on the source pad. Should chain up to the
+parent to let the default handler run (Since 1.2)

+

+
Frame (context) data passed to each frame parsing virtual methods.  In
+addition to providing the data to be checked for a valid frame or an already
+identified frame, it conveys additional metadata or control information
+from and to the subclass w.r.t. the particular frame in question (rather
+than global parameters).  Some of these may apply to each parsing stage, others
+only to some a particular one.  These parameters are effectively zeroed at start
+of each frame's processing, i.e. parsing virtual method invocation sequence.

Property Details

+

+
The “disable-passthrough” property

+
  “disable-passthrough”      gboolean

+
If set to TRUE, baseparse will unconditionally force parsing of the
+incoming data. This can be required in the rare cases where the incoming
+side-data (caps, pts, dts, ...) is not trusted by the user and wants to
+force validation and parsing of the incoming data.
+If set to FALSE, decision of whether to parse the data or not is up to
+the implementation (standard behaviour).

+
Flags: Read / Write

+
Default value: FALSE

Description

+
GstBaseSink is the base class for sink elements in GStreamer, such as
+xvimagesink or filesink. It is a layer on top of GstElement that provides a
+simplified interface to plugin writers. GstBaseSink handles many details
+for you, for example: preroll, clock synchronization, state changes,
+activation in push or pull mode, and queries.

+
In most cases, when writing sink elements, there is no need to implement
+class methods from GstElement or to set functions on pads, because the
+GstBaseSink infrastructure should be sufficient.

+
GstBaseSink provides support for exactly one sink pad, which should be
+named "sink". A sink implementation (subclass of GstBaseSink) should
+install a pad template in its class_init function, like so:

+

+  
+    
+

static void
+my_element_class_init (GstMyElementClass *klass)
+{
+  GstElementClass *gstelement_class = GST_ELEMENT_CLASS (klass);
+
+  // sinktemplate should be a #GstStaticPadTemplate with direction
+  // %GST_PAD_SINK and name "sink"
+  gst_element_class_add_static_pad_template (gstelement_class, &sinktemplate);
+
+  gst_element_class_set_static_metadata (gstelement_class,
+      "Sink name",
+      "Sink",
+      "My Sink element",
+      "The author <my.sink@my.email>");
+}

+

+
+

+
GstBaseSink will handle the prerolling correctly. This means that it will
+return GST_STATE_CHANGE_ASYNC from a state change to PAUSED until the first
+buffer arrives in this element. The base class will call the
+GstBaseSinkClass.preroll() vmethod with this preroll buffer and will then
+commit the state change to the next asynchronously pending state.

+
When the element is set to PLAYING, GstBaseSink will synchronise on the
+clock using the times returned from GstBaseSinkClass.get_times(). If this
+function returns GST_CLOCK_TIME_NONE for the start time, no synchronisation
+will be done. Synchronisation can be disabled entirely by setting the object
+“sync” property to FALSE.

+
After synchronisation the virtual method GstBaseSinkClass.render() will be
+called. Subclasses should minimally implement this method.

+
Subclasses that synchronise on the clock in the GstBaseSinkClass.render()
+method are supported as well. These classes typically receive a buffer in
+the render method and can then potentially block on the clock while
+rendering. A typical example is an audiosink.
+These subclasses can use gst_base_sink_wait_preroll() to perform the
+blocking wait.

+
Upon receiving the EOS event in the PLAYING state, GstBaseSink will wait
+for the clock to reach the time indicated by the stop time of the last
+GstBaseSinkClass.get_times() call before posting an EOS message. When the
+element receives EOS in PAUSED, preroll completes, the event is queued and an
+EOS message is posted when going to PLAYING.

+
GstBaseSink will internally use the GST_EVENT_SEGMENT events to schedule
+synchronisation and clipping of buffers. Buffers that fall completely outside
+of the current segment are dropped. Buffers that fall partially in the
+segment are rendered (and prerolled). Subclasses should do any subbuffer
+clipping themselves when needed.

+
GstBaseSink will by default report the current playback position in
+GST_FORMAT_TIME based on the current clock time and segment information.
+If no clock has been set on the element, the query will be forwarded
+upstream.

+
The GstBaseSinkClass.set_caps() function will be called when the subclass
+should configure itself to process a specific media type.

+
The GstBaseSinkClass.start() and GstBaseSinkClass.stop() virtual methods
+will be called when resources should be allocated. Any
+GstBaseSinkClass.preroll(), GstBaseSinkClass.render() and
+GstBaseSinkClass.set_caps() function will be called between the
+GstBaseSinkClass.start() and GstBaseSinkClass.stop() calls.

+
The GstBaseSinkClass.event() virtual method will be called when an event is
+received by GstBaseSink. Normally this method should only be overridden by
+very specific elements (such as file sinks) which need to handle the
+newsegment event specially.

+
The GstBaseSinkClass.unlock() method is called when the elements should
+unblock any blocking operations they perform in the
+GstBaseSinkClass.render() method. This is mostly useful when the
+GstBaseSinkClass.render() method performs a blocking write on a file
+descriptor, for example.

+
The “max-lateness” property affects how the sink deals with
+buffers that arrive too late in the sink. A buffer arrives too late in the
+sink when the presentation time (as a combination of the last segment, buffer
+timestamp and element base_time) plus the duration is before the current
+time of the clock.
+If the frame is later than max-lateness, the sink will drop the buffer
+without calling the render method.
+This feature is disabled if sync is disabled, the
+GstBaseSinkClass.get_times() method does not return a valid start time or
+max-lateness is set to -1 (the default).
+Subclasses can use gst_base_sink_set_max_lateness() to configure the
+max-lateness value.

+
The “qos” property will enable the quality-of-service features of
+the basesink which gather statistics about the real-time performance of the
+clock synchronisation. For each buffer received in the sink, statistics are
+gathered and a QOS event is sent upstream with these numbers. This
+information can then be used by upstream elements to reduce their processing
+rate, for example.

+
The “async” property can be used to instruct the sink to never
+perform an ASYNC state change. This feature is mostly usable when dealing
+with non-synchronized streams or sparse streams.

+

+

+
Functions

+

+
gst_base_sink_query_latency ()

+
gboolean
+gst_base_sink_query_latency (GstBaseSink *sink,
+                             gboolean *live,
+                             gboolean *upstream_live,
+                             GstClockTime *min_latency,
+                             GstClockTime *max_latency);

+
Query the sink for the latency parameters. The latency will be queried from
+the upstream elements. live
+ will be TRUE if sink
+ is configured to
+synchronize against the clock. upstream_live
+ will be TRUE if an upstream
+element is live.

+
If both live
+ and upstream_live
+ are TRUE, the sink will want to compensate
+for the latency introduced by the upstream elements by setting the
+min_latency
+ to a strictly positive value.

+
This function is mostly used by subclasses.

+
+
+
+
+
+





sink
the sink
 

+

+
gst_base_sink_do_preroll ()

+
GstFlowReturn
+gst_base_sink_do_preroll (GstBaseSink *sink,
+                          GstMiniObject *obj);

+
If the sink
+ spawns its own thread for pulling buffers from upstream it
+should call this method after it has pulled a buffer. If the element needed
+to preroll, this function will perform the preroll and will then block
+until the element state is changed.

+
This function should be called with the PREROLL_LOCK held.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





sink
the sink
 
obj
the mini object that caused the preroll. 
[transfer none]

+

+

+
Returns

+
 GST_FLOW_OK if the preroll completed and processing can
+continue. Any other return value should be returned from the render vmethod.

+

+

+

+

+
gst_base_sink_wait ()

+
GstFlowReturn
+gst_base_sink_wait (GstBaseSink *sink,
+                    GstClockTime time,
+                    GstClockTimeDiff *jitter);

+
This function will wait for preroll to complete and will then block until time
+
+is reached. It is usually called by subclasses that use their own internal
+synchronisation but want to let some synchronization (like EOS) be handled
+by the base class.

+
This function should only be called with the PREROLL_LOCK held (like when
+receiving an EOS event in the ::event vmethod or when handling buffers in
+::render).

+
The time
+ argument should be the running_time of when the timeout should happen
+and will be adjusted with any latency and offset configured in the sink.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+





sink
the sink
 
time
the running_time to be reached
 
jitter
the jitter to be filled with time diff, or NULL. 
[out][allow-none]

+

+

+
Returns

+
 GstFlowReturn

+

+

+

+

+
gst_base_sink_wait_preroll ()

+
GstFlowReturn
+gst_base_sink_wait_preroll (GstBaseSink *sink);

+
If the GstBaseSinkClass.render() method performs its own synchronisation
+against the clock it must unblock when going from PLAYING to the PAUSED state
+and call this method before continuing to render the remaining data.

+
If the GstBaseSinkClass.render() method can block on something else than
+the clock, it must also be ready to unblock immediately on
+the GstBaseSinkClass.unlock() method and cause the
+GstBaseSinkClass.render() method to immediately call this function.
+In this case, the subclass must be prepared to continue rendering where it
+left off if this function returns GST_FLOW_OK.

+
This function will block until a state change to PLAYING happens (in which
+case this function returns GST_FLOW_OK) or the processing must be stopped due
+to a state change to READY or a FLUSH event (in which case this function
+returns GST_FLOW_FLUSHING).

+
This function should only be called with the PREROLL_LOCK held, like in the
+render function.

+

+
Parameters

+

+++++
+
+
+
+
+
+





sink
the sink
 

+

+

+
Returns

+
 GST_FLOW_OK if the preroll completed and processing can
+continue. Any other return value should be returned from the render vmethod.

+

+

+

+

+
gst_base_sink_wait_clock ()

+
GstClockReturn
+gst_base_sink_wait_clock (GstBaseSink *sink,
+                          GstClockTime time,
+                          GstClockTimeDiff *jitter);

+
This function will block until time
+ is reached. It is usually called by
+subclasses that use their own internal synchronisation.

+
If time
+ is not valid, no synchronisation is done and GST_CLOCK_BADTIME is
+returned. Likewise, if synchronisation is disabled in the element or there
+is no clock, no synchronisation is done and GST_CLOCK_BADTIME is returned.

+
This function should only be called with the PREROLL_LOCK held, like when
+receiving an EOS event in the GstBaseSinkClass.event() vmethod or when
+receiving a buffer in
+the GstBaseSinkClass.render() vmethod.

+
The time
+ argument should be the running_time of when this method should
+return and is not adjusted with any latency or offset configured in the
+sink.

get_caps ()
Called to get sink pad caps from the subclass
 
set_caps ()
Notify subclass of changed caps
 
fixate ()
Only useful in pull mode. Implement if you have
+ideas about what should be the default values for the caps you support.
 
activate_pull ()
Subclasses should override this when they can provide an
+alternate method of spawning a thread to drive the pipeline in pull mode.
+Should start or stop the pulling thread, depending on the value of the
+"active" argument. Called after actually activating the sink pad in pull
+mode. The default implementation starts a task on the sink pad.
 
get_times ()
Called to get the start and end times for synchronising
+the passed buffer to the clock
 
propose_allocation ()
configure the allocation query
 
start ()
Start processing. Ideal for opening resources in the subclass
 
stop ()
Stop processing. Subclasses should use this to close resources.
 
unlock ()
Unlock any pending access to the resource. Subclasses should
+unblock any blocked function ASAP and call gst_base_sink_wait_preroll()
 
unlock_stop ()
Clear the previous unlock request. Subclasses should clear
+any state they set during GstBaseSinkClass.unlock(), and be ready to
+continue where they left off after gst_base_sink_wait_preroll(),
+gst_base_sink_wait() or gst_wait_sink_wait_clock() return or
+GstBaseSinkClass.render() is called again.
 
query ()
perform a GstQuery on the element.
 
event ()
Override this to handle events arriving on the sink pad
 
wait_event ()
Override this to implement custom logic to wait for the event
+time (for events like EOS and GAP). Subclasses should always first
+chain up to the default implementation.
 
prepare ()
Called to prepare the buffer for render
+and preroll
+. This
+function is called before synchronisation is performed.
 
prepare_list ()
Called to prepare the buffer list for render_list
+. This
+function is called before synchronisation is performed.
 
preroll ()
Called to present the preroll buffer if desired.
 
render ()
Called when a buffer should be presented or output, at the
+correct moment if the GstBaseSink has been set to sync to the clock.
 
render_list ()
Same as render
+but used with buffer lists instead of
+buffers.

Property Details

+

+
The “async” property

+
  “async”                    gboolean

+
If set to TRUE, the basesink will perform asynchronous state changes.
+When set to FALSE, the sink will not signal the parent when it prerolls.
+Use this option when dealing with sparse streams or when synchronisation is
+not required.

+
Flags: Read / Write

+
Default value: TRUE

+

+

+

+
The “blocksize” property

+
  “blocksize”                guint

+
The amount of bytes to pull when operating in pull mode.

+
Flags: Read / Write

+
Default value: 4096

+

+

+

+
The “enable-last-sample” property

+
  “enable-last-sample”       gboolean

+
Enable the last-sample property. If FALSE, basesink doesn't keep a
+reference to the last buffer arrived and the last-sample property is always
+set to NULL. This can be useful if you need buffers to be released as soon
+as possible, eg. if you're using a buffer pool.

+
Flags: Read / Write

+
Default value: TRUE

+

+

+

+
The “last-sample” property

+
  “last-sample”              GstSample *

+
The last buffer that arrived in the sink and was used for preroll or for
+rendering. This property can be used to generate thumbnails. This property
+can be NULL when the sink has not yet received a buffer.

+
Flags: Read

+

+

+

+
The “max-bitrate” property

+
  “max-bitrate”              guint64

+
Control the maximum amount of bits that will be rendered per second.
+Setting this property to a value bigger than 0 will make the sink delay
+rendering of the buffers when it would exceed to max-bitrate.

+
Flags: Read / Write

+
Default value: 0

+
Since: 1.2

+

+

+

+
The “max-lateness” property

+

+
Generate Quality-of-Service events upstream.

+
Flags: Read / Write

+
Default value: FALSE

+

+

+

+
The “render-delay” property

+
  “render-delay”             guint64

+
The additional delay between synchronisation and actual rendering of the
+media. This property will add additional latency to the device in order to
+make other sinks compensate for the delay.

+
Flags: Read / Write

+
Default value: 0

+

+

+

+
The “sync” property

+
  “sync”                     gboolean

+
Sync on the clock.

The “throttle-time” property

+
  “throttle-time”            guint64

+
The time to insert between buffers. This property can be used to control
+the maximum amount of buffers per second to render. Setting this property
+to a value bigger than 0 will make the sink create THROTTLE QoS events.

+
Flags: Read / Write

+
Default value: 0

+

+

+

+
The “ts-offset” property

+
  “ts-offset”                gint64

+
Controls the final synchronisation, a negative value will render the buffer
+earlier while a positive value delays playback. This property can be
+used to fix synchronisation in bad files.

+
Flags: Read / Write

+
Default value: 0

+

+
Description

+
This is a generic base class for source elements. The following
+types of sources are supported:

+
    
+
  • random access sources like files
    • 
+
  • seekable sources
    • 
+
  • live sources
    • 
+

+
The source can be configured to operate in any GstFormat with the
+gst_base_src_set_format() method. The currently set format determines
+the format of the internal GstSegment and any GST_EVENT_SEGMENT
+events. The default format for GstBaseSrc is GST_FORMAT_BYTES.

+
GstBaseSrc always supports push mode scheduling. If the following
+conditions are met, it also supports pull mode scheduling:

+

+
If all the conditions are met for operating in pull mode, GstBaseSrc is
+automatically seekable in push mode as well. The following conditions must
+be met to make the element seekable in push mode when the format is not
+GST_FORMAT_BYTES:

+

+
When the element does not meet the requirements to operate in pull mode, the
+offset and length in the GstBaseSrcClass.create() method should be ignored.
+It is recommended to subclass GstPushSrc instead, in this situation. If the
+element can operate in pull mode but only with specific offsets and
+lengths, it is allowed to generate an error when the wrong values are passed
+to the GstBaseSrcClass.create() function.

+
GstBaseSrc has support for live sources. Live sources are sources that when
+paused discard data, such as audio or video capture devices. A typical live
+source also produces data at a fixed rate and thus provides a clock to publish
+this rate.
+Use gst_base_src_set_live() to activate the live source mode.

+
A live source does not produce data in the PAUSED state. This means that the
+GstBaseSrcClass.create() method will not be called in PAUSED but only in
+PLAYING. To signal the pipeline that the element will not produce data, the
+return value from the READY to PAUSED state will be
+GST_STATE_CHANGE_NO_PREROLL.

+
A typical live source will timestamp the buffers it creates with the
+current running time of the pipeline. This is one reason why a live source
+can only produce data in the PLAYING state, when the clock is actually
+distributed and running.

+
Live sources that synchronize and block on the clock (an audio source, for
+example) can use gst_base_src_wait_playing() when the
+GstBaseSrcClass.create() function was interrupted by a state change to
+PAUSED.

+
The GstBaseSrcClass.get_times() method can be used to implement pseudo-live
+sources. It only makes sense to implement the GstBaseSrcClass.get_times()
+function if the source is a live source. The GstBaseSrcClass.get_times()
+function should return timestamps starting from 0, as if it were a non-live
+source. The base class will make sure that the timestamps are transformed
+into the current running_time. The base source will then wait for the
+calculated running_time before pushing out the buffer.

+
For live sources, the base class will by default report a latency of 0.
+For pseudo live sources, the base class will by default measure the difference
+between the first buffer timestamp and the start time of get_times and will
+report this value as the latency.
+Subclasses should override the query function when this behaviour is not
+acceptable.

+
There is only support in GstBaseSrc for exactly one source pad, which
+should be named "src". A source implementation (subclass of GstBaseSrc)
+should install a pad template in its class_init function, like so:

+

+{
+  GstElementClass *gstelement_class = GST_ELEMENT_CLASS (klass);
+  // srctemplate should be a #GstStaticPadTemplate with direction
+  // %GST_PAD_SRC and name "src"
+  gst_element_class_add_static_pad_template (gstelement_class, &srctemplate);
+
+  gst_element_class_set_static_metadata (gstelement_class,
+     "Source name",
+     "Source",
+     "My Source element",
+     "The author <my.sink@my.email>");
+}

+

+
+

+

+
Controlled shutdown of live sources in applications

+
Applications that record from a live source may want to stop recording
+in a controlled way, so that the recording is stopped, but the data
+already in the pipeline is processed to the end (remember that many live
+sources would go on recording forever otherwise). For that to happen the
+application needs to make the source stop recording and send an EOS
+event down the pipeline. The application would then wait for an
+EOS message posted on the pipeline's bus to know when all data has
+been processed and the pipeline can safely be stopped.

+
An application may send an EOS event to a source element to make it
+perform the EOS logic (send EOS event downstream or post a
+GST_MESSAGE_SEGMENT_DONE on the bus). This can typically be done
+with the gst_element_send_event() function on the element or its parent bin.

+
After the EOS has been sent to the element, the application should wait for
+an EOS message to be posted on the pipeline's bus. Once this EOS message is
+received, it may safely shut down the entire pipeline.

+

+

+

+
Functions

+

+
gst_base_src_wait_playing ()

+
GstFlowReturn
+gst_base_src_wait_playing (GstBaseSrc *src);

+
If the GstBaseSrcClass.create() method performs its own synchronisation
+against the clock it must unblock when going from PLAYING to the PAUSED state
+and call this method before continuing to produce the remaining data.

+
This function will block until a state change to PLAYING happens (in which
+case this function returns GST_FLOW_OK) or the processing must be stopped due
+to a state change to READY or a FLUSH event (in which case this function
+returns GST_FLOW_FLUSHING).

+

+
Parameters

+

+++++
+
+
+
+
+
+





src
the src
 

+

+

+
Returns

+
 GST_FLOW_OK if src
+is PLAYING and processing can
+continue. Any other return value should be returned from the create vmethod.

+

+

+

+

+
gst_base_src_start_wait ()

+
GstFlowReturn
+gst_base_src_start_wait (GstBaseSrc *basesrc);

+
Wait until the start operation completes.

+

+
Parameters

+

+++++
+
+
+
+
+
+





basesrc
base source instance
 

+

+

+
Returns

+
 a GstFlowReturn.

+

+
gst_base_src_start_complete ()

+
void
+gst_base_src_start_complete (GstBaseSrc *basesrc,
+                             GstFlowReturn ret);

+
Complete an asynchronous start operation. When the subclass overrides the
+start method, it should call gst_base_src_start_complete() when the start
+operation completes either from the same thread or from an asynchronous
+helper thread.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+

+

+

+

+
gst_base_src_is_live ()

+
gboolean
+gst_base_src_is_live (GstBaseSrc *src);

+
Check if an element is in live mode.

+

+
Parameters

+

+++++
+
+
+
+
+
+





src
base source instance
 

+

+

+
Returns

+
 TRUE if element is in live mode.

+

+

+

+

+
gst_base_src_set_live ()

+
void
+gst_base_src_set_live (GstBaseSrc *src,
+                       gboolean live);

+
If the element listens to a live source, live
+ should
+be set to TRUE.

+
A live source will not produce data in the PAUSED state and
+will therefore not be able to participate in the PREROLL phase
+of a pipeline. To signal this fact to the application and the
+pipeline, the state change return value of the live source will
+be GST_STATE_CHANGE_NO_PREROLL.

+

+

gst_base_src_set_format ()

+
void
+gst_base_src_set_format (GstBaseSrc *src,
+                         GstFormat format);

+
Sets the default format of the source. This will be the format used
+for sending SEGMENT events and for performing seeks.

+
If a format of GST_FORMAT_BYTES is set, the element will be able to
+operate in pull mode if the GstBaseSrcClass.is_seekable() returns TRUE.

+
This function must only be called in states < GST_STATE_PAUSED.

+                            GstClockTime *max_latency);

+
Query the source for the latency parameters. live
+ will be TRUE when src
+ is
+configured as a live source. min_latency
+ and max_latency
+ will be set
+to the difference between the running time and the timestamp of the first

Lets GstBaseSrc sub-classes to know the memory allocator
+
+used by the base class and its params
+.

+
Unref the allocator
+ after usage.

GstBufferPool *
+gst_base_src_get_buffer_pool (GstBaseSrc *src);

+

+
Parameters

+

+++++
+
+
+
+
+
+





src

+

+
gst_base_src_is_async ()

+
gboolean
+gst_base_src_is_async (GstBaseSrc *src);

+
Get the current async behaviour of src
+. See also gst_base_src_set_async().

+

+
Parameters

+

+++++
+
+
+
+
+
+





src
base source instance
 

+

+

+
Returns

+
 TRUE if src
+is operating in async mode.

+

+

+

+

+
gst_base_src_set_async ()

+
void
+gst_base_src_set_async (GstBaseSrc *src,
+                        gboolean async);

+
Configure async behaviour in src
+, no state change will block. The open,
+close, start, stop, play and pause virtual methods will be executed in a
+different thread and are thus allowed to perform blocking operations. Any
+blocking operation should be unblocked with the unlock vmethod.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+

+
gst_base_src_submit_buffer_list ()

void
+gst_base_src_submit_buffer_list (GstBaseSrc *src,
+                                 GstBufferList *buffer_list);

+
Subclasses can call this from their create virtual method implementation
+to submit a buffer list to be pushed out later. This is useful in
+cases where the create function wants to produce multiple buffers to be
+pushed out in one go in form of a GstBufferList, which can reduce overhead
+drastically, especially for packetised inputs (for data streams where
+the packetisation/chunking is not important it is usually more efficient
+to return larger buffers instead).

+
Subclasses that use this function from their create function must return
+GST_FLOW_OK and no buffer from their create virtual method implementation.
+If a buffer is returned after a buffer list has also been submitted via this
+function the behaviour is undefined.

+
Subclasses must only call this function once per create function call and
+subclasses must only call this function when the source operates in push
+mode.

get_caps ()
Called to get the caps to report
 
negotiate ()
Negotiated the caps with the peer.
 
fixate ()
Called during negotiation if caps need fixating. Implement instead of
+setting a fixate function on the source pad.
 
set_caps ()
Notify subclass of changed output caps
 
decide_allocation ()
configure the allocation query
 
start ()
Start processing. Subclasses should open resources and prepare
+to produce data. Implementation should call gst_base_src_start_complete()
+when the operation completes, either from the current thread or any other
+thread that finishes the start operation asynchronously.
 
stop ()
Stop processing. Subclasses should use this to close resources.
 
get_times ()
Given a buffer, return the start and stop time when it
+should be pushed out. The base class will sync on the clock using
+these times.
 
get_size ()
Return the total size of the resource, in the format set by
+gst_base_src_set_format().
 
is_seekable ()
Check if the source can seek
 
prepare_seek_segment ()
Prepare the GstSegment that will be passed to the
+GstBaseSrcClass.do_seek() vmethod for executing a seek
+request. Sub-classes should override this if they support seeking in
+formats other than the configured native format. By default, it tries to
+convert the seek arguments to the configured native format and prepare a
+segment in that format.
 
do_seek ()
Perform seeking on the resource to the indicated segment.
 
unlock ()
Unlock any pending access to the resource. Subclasses should unblock
+any blocked function ASAP. In particular, any create() function in
+progress should be unblocked and should return GST_FLOW_FLUSHING. Any
+future GstBaseSrcClass.create() function call should also return
+GST_FLOW_FLUSHING until the GstBaseSrcClass.unlock_stop() function has
+been called.
 
unlock_stop ()
Clear the previous unlock request. Subclasses should clear any
+state they set during GstBaseSrcClass.unlock(), such as clearing command
+queues.
 
query ()
Handle a requested query.
 
event ()
Override this to implement custom event handling.
 
create ()
Ask the subclass to create a buffer with offset and size.  When the
+subclass returns GST_FLOW_OK, it MUST return a buffer of the requested size
+unless fewer bytes are available because an EOS condition is near. No
+buffer should be returned when the return value is different from
+GST_FLOW_OK. A return value of GST_FLOW_EOS signifies that the end of
+stream is reached. The default implementation will call
+GstBaseSrcClass.alloc() and then call GstBaseSrcClass.fill().
 
alloc ()
Ask the subclass to allocate a buffer with for offset and size. The
+default implementation will create a new buffer from the negotiated allocator.
 
fill ()
Ask the subclass to fill the buffer with data for offset and size. The
+passed buffer is guaranteed to hold the requested amount of bytes.

Includes

+

+

+
Description

+
This base class is for filter elements that process data. Elements
+that are suitable for implementation using GstBaseTransform are ones
+where the size and caps of the output is known entirely from the input
+caps and buffer sizes. These include elements that directly transform
+one buffer into another, modify the contents of a buffer in-place, as
+well as elements that collate multiple input buffers into one output buffer,
+or that expand one input buffer into multiple output buffers. See below
+for more concrete use cases.

+
It provides for:

+
    
+
  • one sinkpad and one srcpad
    • 
+
  • Possible formats on sink and source pad implemented
+with custom transform_caps function. By default uses
+same format on sink and source.
    • 
+
  • Handles state changes
    • 
+
  • Does flushing
    • 
+
  • Push mode
    • 
+
  • Pull mode if the sub-class transform can operate on arbitrary data
    • 
+

+

+
Use Cases

+

+
Passthrough mode

+
    
+
  • Element has no interest in modifying the buffer. It may want to inspect it,
+in which case the element should have a transform_ip function. If there
+is no transform_ip function in passthrough mode, the buffer is pushed
+intact.
    • 
+
  • The GstBaseTransformClass.passthrough_on_same_caps variable
+will automatically set/unset passthrough based on whether the
+element negotiates the same caps on both pads.
    • 
+
  • GstBaseTransformClass.passthrough_on_same_caps on an element that
+doesn't implement a transform_caps function is useful for elements that
+only inspect data (such as level)
    • 
+
  • 
+
    Example elements
    
+
      
+
    • Level
      • 
+
    • Videoscale, audioconvert, videoconvert, audioresample in certain modes.
      • 
+
    
+
    • 
+

+

+

+
Modifications in-place - input buffer and output buffer are the same thing.

+
    
+
  • The element must implement a transform_ip function.
    • 
+
  • Output buffer size must <= input buffer size
    • 
+
  • If the always_in_place flag is set, non-writable buffers will be copied
+and passed to the transform_ip function, otherwise a new buffer will be
+created and the transform function called.
    • 
+
  • Incoming writable buffers will be passed to the transform_ip function
+immediately.
    • 
+
  • 
+
    only implementing transform_ip and not transform implies always_in_place = TRUE
    
+
    • 
+
      Example elements:
      
+
        
+
      • Volume
        • 
+
      • Audioconvert in certain modes (signed/unsigned conversion)
        • 
+
      • videoconvert in certain modes (endianness swapping)
        • 
+
      
+
    
+
    • 
+

+

+

+
Modifications only to the caps/metadata of a buffer

+
    
+
  • The element does not require writable data, but non-writable buffers
+should be subbuffered so that the meta-information can be replaced.
    • 
+
  • Elements wishing to operate in this mode should replace the
+prepare_output_buffer method to create subbuffers of the input buffer
+and set always_in_place to TRUE
    • 
+
  • 
+
    Example elements
    
+
      
+
    • Capsfilter when setting caps on outgoing buffers that have
+none.
      • 
+
    • identity when it is going to re-timestamp buffers by
+datarate.
      • 
+
    
+
    • 
+

+

+

+
Normal mode

+
    
+
  • always_in_place flag is not set, or there is no transform_ip function
    • 
+
  • Element will receive an input buffer and output buffer to operate on.
    • 
+
  • Output buffer is allocated by calling the prepare_output_buffer function.
    • 
+
  • 
+
    Example elements:
    
+
    • Videoscale, videoconvert, audioconvert when doing
+scaling/conversions
    
+
    • 
+

+

+

+
Special output buffer allocations

+
    
+
  • Elements which need to do special allocation of their output buffers
+beyond allocating output buffers via the negotiated allocator or
+buffer pool should implement the prepare_output_buffer method.
    • 
+
  • 
+
    Example elements:
    
+
    • efence
    
+
    • 
+

+

+

+

+

+
Sub-class settable flags on GstBaseTransform

+
    
+
  • 
+
    passthrough
    
+
      
+
    • Implies that in the current configuration, the sub-class is not interested in modifying the buffers.
      • 
+
    • Elements which are always in passthrough mode whenever the same caps has been negotiated on both pads can set the class variable passthrough_on_same_caps to have this behaviour automatically.
      • 
+
    
+
    • 
+
  • 
+
    always_in_place
    
+
      
+
    • Determines whether a non-writable buffer will be copied before passing
+to the transform_ip function.
      • 
+
    • Implied TRUE if no transform function is implemented.
      • 
+
    • Implied FALSE if ONLY transform function is implemented.

Parameters

+

+++++
+
+
+
+
+
+





trans
the GstBaseTransform to query
 

+

+

+
Returns

+
 TRUE is the transform is configured in passthrough mode.

+

+

+

+

+

+
gst_base_transform_set_passthrough ()

+
void
+gst_base_transform_set_passthrough (GstBaseTransform *trans,
+                                    gboolean passthrough);

+
Set passthrough mode for this filter by default. This is mostly
+useful for filters that do not care about negotiation.

+
Always TRUE for filters which don't implement either a transform
+or transform_ip method.

+
MT safe.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+

trans
the GstBaseTransform to set
 
passthrough
boolean indicating passthrough mode.
 

+

+

+

+

+
gst_base_transform_set_prefer_passthrough ()

+
void
+gst_base_transform_set_prefer_passthrough
+                               (GstBaseTransform *trans,
+                                gboolean prefer_passthrough);

+
If prefer_passthrough
+ is TRUE (the default), trans
+ will check and
+prefer passthrough caps from the list of caps returned by the
+transform_caps vmethod.

+
If set to FALSE, the element must order the caps returned from the
+transform_caps function in such a way that the preferred format is
+first in the list. This can be interesting for transforms that can do
+passthrough transforms but prefer to do something else, like a
+capsfilter.

void
+gst_base_transform_set_gap_aware (GstBaseTransform *trans,
+                                  gboolean gap_aware);

+
If gap_aware
+ is FALSE (the default), output buffers will have the
+GST_BUFFER_FLAG_GAP flag unset.

+
If set to TRUE, the element must handle output buffers with this flag set
+correctly, i.e. it can assume that the buffer contains neutral data but must
+unset the flag if the output is no neutral data.

gboolean passthrough_on_same_caps;
If set to TRUE, passthrough mode will be
+automatically enabled if the caps are the same.
+Set to FALSE by default.
 
gboolean transform_ip_on_passthrough;
If set to TRUE, transform_ip
+will be called in
+passthrough mode. The passed buffer might not be
+writable. When FALSE, neither transform
+nor
+transform_ip
+will be called in passthrough mode.
+Set to TRUE by default.
 
transform_caps ()
Optional.  Given the pad in this direction and the given
+caps, what caps are allowed on the other pad in this
+element ?
 
fixate_caps ()
Optional. Given the pad in this direction and the given
+caps, fixate the caps on the other pad. The function takes
+ownership of othercaps
+and returns a fixated version of
+othercaps
+. othercaps
+is not guaranteed to be writable.
 
accept_caps ()
Optional.
+Subclasses can override this method to check if caps
+can be
+handled by the element. The default implementation might not be
+the most optimal way to check this in all cases.
 
set_caps ()
allows the subclass to be notified of the actual caps set.
 
query ()
Optional.
+Handle a requested query. Subclasses that implement this
+should must chain up to the parent if they didn't handle the
+query
 
decide_allocation ()
Setup the allocation parameters for allocating output
+buffers. The passed in query contains the result of the
+downstream allocation query. This function is only called
+when not operating in passthrough mode. The default
+implementation will remove all memory dependent metadata.
+If there is a filter_meta
+method implementation, it will
+be called for all metadata API in the downstream query,
+otherwise the metadata API is removed.
 
filter_meta ()
Return TRUE if the metadata API should be proposed in the
+upstream allocation query. The default implementation is NULL
+and will cause all metadata to be removed.
 
propose_allocation ()
Propose buffer allocation parameters for upstream elements.
+This function must be implemented if the element reads or
+writes the buffer content. The query that was passed to
+the decide_allocation is passed in this method (or NULL
+when the element is in passthrough mode). The default
+implementation will pass the query downstream when in
+passthrough mode and will copy all the filtered metadata
+API in non-passthrough mode.
 
transform_size ()
Optional. Given the size of a buffer in the given direction
+with the given caps, calculate the size in bytes of a buffer
+on the other pad with the given other caps.
+The default implementation uses get_unit_size and keeps
+the number of units the same.
 
get_unit_size ()
Required if the transform is not in-place.
+get the size in bytes of one unit for the given caps.
 
start ()
Optional.
+Called when the element starts processing.
+Allows opening external resources.
 
stop ()
Optional.
+Called when the element stops processing.
+Allows closing external resources.
 
sink_event ()
Optional.
+Event handler on the sink pad. The default implementation
+handles the event and forwards it downstream.
 
src_event ()
Optional.
+Event handler on the source pad. The default implementation
+handles the event and forwards it upstream.
 
prepare_output_buffer ()
Optional.
+Subclasses can override this to do their own
+allocation of output buffers.  Elements that only do
+analysis can return a subbuffer or even just
+return a reference to the input buffer (if in
+passthrough mode). The default implementation will
+use the negotiated allocator or bufferpool and
+transform_size to allocate an output buffer or it
+will return the input buffer in passthrough mode.
 
copy_metadata ()
Optional.
+Copy the metadata from the input buffer to the output buffer.
+The default implementation will copy the flags, timestamps and
+offsets of the buffer.
 
transform_meta ()
Optional. Transform the metadata on the input buffer to the
+output buffer. By default this method copies all meta without
+tags. subclasses can implement this method and return TRUE if
+the metadata is to be copied.
 
before_transform ()
Optional.
+This method is called right before the base class will
+start processing. Dynamic properties or other delayed
+configuration could be performed in this method.
 
transform ()
Required if the element does not operate in-place.
+Transforms one incoming buffer to one outgoing buffer.
+The function is allowed to change size/timestamp/duration
+of the outgoing buffer.
 
transform_ip ()
Required if the element operates in-place.
+Transform the incoming buffer in-place.
 
submit_input_buffer ()
Function which accepts a new input buffer and pre-processes it.
+The default implementation performs caps (re)negotiation, then
+QoS if needed, and places the input buffer into the queued_buf
+member variable. If the buffer is dropped due to QoS, it returns
+GST_BASE_TRANSFORM_FLOW_DROPPED. If this input buffer is not
+contiguous with any previous input buffer, then is_discont
+is set to TRUE. (Since 1.6)
 
generate_output ()
Called after each new input buffer is submitted repeatedly
+until it either generates an error or fails to generate an output
+buffer. The default implementation takes the contents of the
+queued_buf
+variable, generates an output buffer if needed
+by calling the class prepare_output_buffer
+, and then
+calls either transform
+or transform_ip
+. Elements that don't
+do 1-to-1 transformations on input to output buffers can either
+return GST_BASE_TRANSFORM_FLOW_DROPPED or simply not generate
+an output buffer until they are ready to do so. (Since 1.6)
 

+

  • Collectpads are created with gst_collect_pads_new(). A callback should then
+be installed with gst_collect_pads_set_function().
    • 
+
  • Pads are added to the collection with gst_collect_pads_add_pad()/
+gst_collect_pads_remove_pad(). The pad has to be a sinkpad. When added,
+the chain, event and query functions of the pad are overridden. The
+element_private of the pad is used to store private information for the
+collectpads.
    • 
+
  • For each pad, data is queued in the _chain function or by
+performing a pull_range.
    • 
+
  • When data is queued on all pads in waiting mode, the callback function is called.
    • 
+
  • Data can be dequeued from the pad with the gst_collect_pads_pop() method.
+One can peek at the data with the gst_collect_pads_peek() function.
+These functions will return NULL if the pad received an EOS event. When all
+pads return NULL from a gst_collect_pads_peek(), the element can emit an EOS
+event itself.
    • 
+
  • Data can also be dequeued in byte units using the gst_collect_pads_available(),
+gst_collect_pads_read_buffer() and gst_collect_pads_flush() calls.
    • 
+
  • Elements should call gst_collect_pads_start() and gst_collect_pads_stop() in
+their state change functions to start and stop the processing of the collectpads.
+The gst_collect_pads_stop() call should be called before calling the parent
+element state change function in the PAUSED_TO_READY state change to ensure
+no pad is blocked and the element can finish streaming.
    • 
+
  • gst_collect_pads_set_waiting() sets a pad to waiting or non-waiting mode.
+CollectPads element is not waiting for data to be collected on non-waiting pads.
+Thus these pads may but need not have data when the callback is called.
+All pads are in waiting mode by default.

+                          gboolean lock);

+
Add a pad to the collection of collect pads. The pad has to be
+a sinkpad. The refcount of the pad is incremented. Use
+gst_collect_pads_remove_pad() to remove the pad from the collection
+again.

+
You specify a size for the returned GstCollectData structure
+so that you can use it to store additional information.

+
You can also specify a GstCollectDataDestroyNotify that will be called
+just before the GstCollectData structure is freed. It is passed the
+pointer to the structure and should free any custom memory and resources
+allocated for it.

+
Keeping a pad locked in waiting state is only relevant when using
+the default collection algorithm (providing the oldest buffer).
+It ensures a buffer must be available on this pad for a collection
+to take place.  This is of typical use to a muxer element where
+non-subtitle streams should always be in waiting state,
+e.g. to assure that caps information is available on all these streams
+when initial headers have to be written.

+
The pad will be automatically activated in push mode when pads
+ is
+started.

+                               gpointer user_data);

+
CollectPads provides a default collection algorithm that will determine
+the oldest buffer available on all of its pads, and then delegate
+to a configured callback.
+However, if circumstances are more complicated and/or more control
+is desired, this sets a callback that will be invoked instead when
+all the pads added to the collection have buffers queued.
+Evidently, this callback is not compatible with
+gst_collect_pads_set_buffer_function() callback.
+If this callback is set, the former will be unset.

Description

+
A value mapping object that attaches control sources to gobject properties. It
+will map the control values directly to the target property range. If a
+non-absolute direct control binding is used, the value range [0.0 ... 1.0]
+is mapped to full target property range, and all values outside the range
+will be clipped. An absolute control binding will not do any value
+transformations.

Description

+
GstNetClientClock implements a custom GstClock that synchronizes its time
+to a remote time provider such as GstNetTimeProvider. GstNtpClock
+implements a GstClock that synchronizes its time to a remote NTPv4 server.

+
A new clock is created with gst_net_client_clock_new() or
+gst_ntp_clock_new(), which takes the address and port of the remote time
+provider along with a name and an initial time.

+
This clock will poll the time provider and will update its calibration
+parameters based on the local and remote observations.

+
The "round-trip" property limits the maximum round trip packets can take.

+
Various parameters of the clock can be configured with the parent GstClock
+"timeout", "window-size" and "window-threshold" object properties.

+
A GstNetClientClock and GstNtpClock is typically set on a GstPipeline with
+gst_pipeline_use_clock().

+
If you set a GstBus on the clock via the "bus" object property, it will
+send GST_MESSAGE_ELEMENT
+ messages with an attached GstStructure containing
+statistics about clock accuracy and network traffic.

+

Description

+
GstPtpClock implements a PTP (IEEE1588:2008) ordinary clock in slave-only
+mode, that allows a GStreamer pipeline to synchronize to a PTP network
+clock in some specific domain.

+
The PTP subsystem can be initialized with gst_ptp_init(), which then starts
+a helper process to do the actual communication via the PTP ports. This is
+required as PTP listens on ports < 1024 and thus requires special
+privileges. Once this helper process is started, the main process will
+synchronize to all PTP domains that are detected on the selected
+interfaces.

+
gst_ptp_clock_new() then allows to create a GstClock that provides the PTP
+time from a master clock inside a specific PTP domain. This clock will only
+return valid timestamps once the timestamps in the PTP domain are known. To
+check this, you can use gst_clock_wait_for_sync(), the GstClock::synced
+signal and gst_clock_is_synced().

+
To gather statistics about the PTP clock synchronization,
+gst_ptp_statistics_callback_add() can be used. This gives the application
+the possibility to collect all kinds of statistics from the clock
+synchronization.

+
gboolean
+gst_ptp_init (guint64 clock_id,
+              gchar **interfaces);

+
Initialize the GStreamer PTP subsystem and create a PTP ordinary clock in
+slave-only mode for all domains on the given interfaces
+ with the
+given clock_id
+.

+
If clock_id
+ is GST_PTP_CLOCK_ID_NONE, a clock id is automatically
+generated from the MAC address of the first network interface.

+
This function is automatically called by gst_ptp_clock_new() with default
+parameters if it wasn't called before.

+

+
Parameters

network interfaces to run the clock on. 
[transfer none][array zero-terminated=1][allow-none]

+

+

+
Returns

+
 TRUE if the GStreamer PTP clock subsystem could be initialized.

+

+
Since: 1.6

+

+

+

+
gst_ptp_deinit ()

+
void
+gst_ptp_deinit (void);

+
Deinitialize the GStreamer PTP subsystem and stop the PTP clock. If there
+are any remaining GstPtpClock instances, they won't be further synchronized
+to the PTP network clock.

+
Since: 1.6

+

+

+

+
gst_ptp_is_initialized ()

+
gboolean
+gst_ptp_is_initialized (void);

+
Check if the GStreamer PTP clock subsystem is initialized.

+

+
Returns

+
 TRUE if the GStreamer PTP clock subsystem is intialized.

+

+
Since: 1.6

+

+

+

+
gst_ptp_is_supported ()

+
gboolean
+gst_ptp_is_supported (void);

+
Check if PTP clocks are generally supported on this system, and if previous
+initializations did not fail.

+

+
Returns

+
 TRUE if PTP clocks are generally supported on this system, and
+previous initializations did not fail.

+

+
Since: 1.6

+

+

+

+
gst_ptp_clock_new ()

+
GstClock *
+gst_ptp_clock_new (const gchar *name,
+                   guint domain);

+
Creates a new PTP clock instance that exports the PTP time of the master
+clock in domain
+. This clock can be slaved to other clocks as needed.

+
If gst_ptp_init() was not called before, this will call gst_ptp_init() with
+default parameters.

+
This clock only returns valid timestamps after it received the first
+times from the PTP master clock on the network. Once this happens the
+GstPtpClock::internal-clock property will become non-NULL. You can
+check this with gst_clock_wait_for_sync(), the GstClock::synced signal and
+gst_clock_is_synced().

Description

+
This class is mostly useful for elements that cannot do
+random access, or at least very slowly. The source usually
+prefers to push out a fixed size buffer.

+
Subclasses usually operate in a format that is different from the
+default GST_FORMAT_BYTES format of GstBaseSrc.

+
Classes extending this base class will usually be scheduled
+in a push based mode. If the peer accepts to operate without
+offsets and within the limits of the allowed block size, this
+class can operate in getrange based mode automatically. To make
+this possible, the subclass should implement and override the
+SCHEDULING query.

+
The subclass should extend the methods from the baseclass in
+addition to the ::create method.

+
Seeking, flushing, scheduling and sync is all handled by this
+base class.

+};
+

+
Subclasses can override any of the available virtual methods or not, as
+needed. At the minimum, the fill
+ method should be overridden to produce
+buffers.

alloc ()
Ask the subclass to allocate a buffer. The subclass decides which

+a new buffer from the negotiated allocator.
 
fill ()
Ask the subclass to fill the buffer with data.

Description

+
GstTestClock is an implementation of GstClock which has different
+behaviour compared to GstSystemClock. Time for GstSystemClock advances
+according to the system time, while time for GstTestClock changes only
+when gst_test_clock_set_time() or gst_test_clock_advance_time() are
+called. GstTestClock provides unit tests with the possibility to
+precisely advance the time in a deterministic manner, independent of the
+system time or any other external factors.

+

+
+

+
GstClock allows for setting up single shot or periodic clock notifications
+as well as waiting for these notifications synchronously (using
+gst_clock_id_wait()) or asynchronously (using gst_clock_id_wait_async() or
+gst_clock_id_wait_async()). This is used by many GStreamer elements,
+among them GstBaseSrc and GstBaseSink.

+
GstTestClock keeps track of these clock notifications. By calling
+gst_test_clock_wait_for_next_pending_id() or
+gst_test_clock_wait_for_multiple_pending_ids() a unit tests may wait for the
+next one or several clock notifications to be requested. Additionally unit
+tests may release blocked waits in a controlled fashion by calling
+gst_test_clock_process_next_clock_id(). This way a unit test can control the
+inaccuracy (jitter) of clock notifications, since the test can decide to
+release blocked waits when the clock time has advanced exactly to, or past,
+the requested clock notification time.

+
There are also interfaces for determining if a notification belongs to a
+GstTestClock or not, as well as getting the number of requested clock
+notifications so far.

+
N.B.: When a unit test waits for a certain amount of clock notifications to
+be requested in gst_test_clock_wait_for_next_pending_id() or
+gst_test_clock_wait_for_multiple_pending_ids() then these functions may block
+for a long time. If they block forever then the expected clock notifications
+were never requested from GstTestClock, and so the assumptions in the code
+of the unit test are wrong. The unit test case runner in gstcheck is
+expected to catch these cases either by the default test case timeout or the
+one set for the unit test by calling tcase_set_timeout().

+
The sample code below assumes that the element under test will delay a
+buffer pushed on the source pad by some latency until it arrives on the sink
+pad. Moreover it is assumed that the element will at some point call
+gst_clock_id_wait() to synchronously wait for a specific time. The first
+buffer sent will arrive exactly on time only delayed by the latency. The
+second buffer will arrive a little late (7ms) due to simulated jitter in the
+clock notification.

+

Since GstTestClock is only supposed to be used in unit tests it calls
+g_assert(), g_assert_cmpint() or g_assert_cmpuint() to validate all function
+arguments. This will highlight any issues with the unit test code itself.

Property Details

+

+
The “clock-type” property

+
  “clock-type”               GstClockType

+
The kind of clock implementation to be reported by this clock.

+
Flags: Read / Write

+
Default value: GST_CLOCK_TYPE_MONOTONIC

+

+

+

+
The “start-time” property

+
  “start-time”               guint64

+
When a GstTestClock is constructed it will have a certain start time set.
+If the clock was created using gst_test_clock_new_with_start_time() then
+this property contains the value of the start_time
+ argument. If
+gst_test_clock_new() was called the clock started at time zero, and thus
+this property contains the value 0.

+
Flags: Read / Write / Construct Only

+
Default value: 0

Description

+
GstTriggerControlSource is a GstControlSource, that returns values from user-given
+control points. It allows for a tolerance on the time-stamps.

+
To use GstTriggerControlSource get a new instance by calling
+gst_trigger_control_source_new(), bind it to a GParamSpec and set some
+control points by calling gst_timed_value_control_source_set().

+
All functions are MT-safe.

+

+

+
Functions

+

+
gst_trigger_control_source_new ()

+

#include <gst/base/gstbitreader.h>
+

+

+

+
Description

+
GstBitReader provides a bit reader that can read any number of bits
+from a memory buffer. It provides functions for reading any number of bits
+into 8, 16, 32 and 64 bit variables.

+

+

+
Functions

+

+
GST_BIT_READER_INIT()

+
#define GST_BIT_READER_INIT(data, size) {data, size, 0, 0}
+

+
A GstBitReader must be initialized with this macro, before it can be
+used. This macro can used be to initialize a variable, but it cannot
+be assigned to a variable. In that case you have to use
+gst_bit_reader_init().

+GstBuffer *

+void
+

+

+

+
Includes

+
#include <gst/check/gstbufferstraw.h>
+

+

+

+
Description

+
These macros and functions are for internal use of the unit tests found
+inside the 'check' directories of various GStreamer packages.

+

+

+
Functions

+

+
gst_buffer_straw_start_pipeline ()

+
void
+gst_buffer_straw_start_pipeline (GstElement *bin,
+                                 GstPad *pad);

+
Sets up a pipeline for buffer sucking. This will allow you to call
+gst_buffer_straw_get_buffer() to access buffers as they pass over pad
+.

+
This function is normally used in unit tests that want to verify that a
+particular element is outputting correct buffers. For example, you would make
+a pipeline via gst_parse_launch(), pull out the pad you want to monitor, then
+call gst_buffer_straw_get_buffer() to get the buffers that pass through pad
+.
+The pipeline will block until you have sucked off the buffers.

+
This function will set the state of bin
+ to PLAYING; to clean up, be sure to
+call gst_buffer_straw_stop_pipeline().

+
Note that you may not start two buffer straws at the same time. This function
+is intended for unit tests, not general API use. In fact it calls fail_if
+from libcheck, so you cannot use it outside unit tests.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





bin
the pipeline to run
 
pad
a pad on an element in bin
+
 

+

+

+

+

+
gst_buffer_straw_get_buffer ()

+
GstBuffer *
+gst_buffer_straw_get_buffer (GstElement *bin,
+                             GstPad *pad);

+
Get one buffer from pad
+. Implemented via buffer probes. This function will
+block until the pipeline passes a buffer over pad
+, so for robust behavior
+in unit tests, you need to use check's timeout to fail out in the case that a
+buffer never arrives.

+
You must have previously called gst_buffer_straw_start_pipeline() on
+pipeline
+ and pad
+.

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





bin
the pipeline previously started via gst_buffer_straw_start_pipeline()
 
pad
the pad previously passed to gst_buffer_straw_start_pipeline()
 

+

+

+
Returns

+
 the captured GstBuffer.

+

+

+

+

+
gst_buffer_straw_stop_pipeline ()

+
void
+gst_buffer_straw_stop_pipeline (GstElement *bin,
+                                GstPad *pad);

+
Set bin
+ to GST_STATE_NULL and release resource allocated in
+gst_buffer_straw_start_pipeline().

+
You must have previously called gst_buffer_straw_start_pipeline() on
+pipeline
+ and pad
+.

 GstByteReader

+

+

+
Includes

+
#include <gst/base/gstbytereader.h>
+

+

+

+
Description

+
GstByteReader provides a byte reader that can read different integer and
+floating point types from a memory buffer. It provides functions for reading
+signed/unsigned, little/big endian integers of 8, 16, 24, 32 and 64 bits
+and functions for reading little/big endian floating points numbers of
+32 and 64 bits. It also provides functions to read NUL-terminated strings
+in various character encodings.

+

+

+
Functions

+

+
GST_BYTE_READER_INIT()

+
#define GST_BYTE_READER_INIT(data, size) {data, size, 0}
+

+
A GstByteReader must be initialized with this macro, before it can be
+used. This macro can used be to initialize a variable, but it cannot
+be assigned to a variable. In that case you have to use
+gst_byte_reader_init().

+

+
Parameters

+

+++++
+
+
+
+
+
+
+
+
+
+
+
+
+





data
Data from which the GstByteReader should read
 
size

+
GstByteReader *
+gst_byte_reader_new (const guint8 *data,
+                     guint size);

+
Create a new GstByteReader instance, which will read from data
+.

+
Free-function: gst_byte_reader_free

+

+

+

+

+

+
gst_byte_reader_free ()

+
void
+gst_byte_reader_free (GstByteReader *reader);

+
Frees a GstByteReader instance, which was previously allocated by
+gst_byte_reader_new().

+

+
Parameters

+

+                      const guint8 *data,
+                      guint size);

+
Initializes a GstByteReader instance to read from data
+. This function
+can be called on already initialized instances.

+

+
Parameters

+                                 GstByteReader *sub_reader,
+                                 guint size);

+
Initializes a GstByteReader sub-reader instance to contain size
+ bytes of
+data from the current position of reader
+. This is useful to read chunked
+formats and make sure that one doesn't read beyond the size of the sub-chunk.

+
Unlike gst_byte_reader_get_sub_reader(), this function does not modify the
+current position of reader
+.

#include <gst/check/gstcheck.h>
+

+

+

+
Description

+
These macros and functions are for internal use of the unit tests found
+inside the 'check' directories of various GStreamer packages.

+
One notable feature is that one can use the environment variables GST_CHECKS
+and GST_CHECKS_IGNORE to select which tests to run or skip. Both variables
+can contain a comma separated list of test name globs (e.g. test_*).

+

+

+

+

+
Description

+
GstDataQueue is an object that handles threadsafe queueing of objects. It
+also provides size-related functionality. This object should be used for
+any GstElement that wishes to provide some sort of queueing functionality.

+

+

+
Functions

+

+
GstDataQueueCheckFullFunction ()

+
gboolean
+(*GstDataQueueCheckFullFunction) (GstDataQueue *queue,
+                                  guint visible,
+                                  guint bytes,
+                                  guint64 time,
+                                  gpointer checkdata);

+
The prototype of the function used to inform the queue that it should be
+considered as full.

queue
a GstDataQueue.
 
visible
The number of visible items currently in the queue.
 
bytes
The amount of bytes currently in the queue.
 
time
The accumulated duration of the items currently in the queue.
 
checkdata
The gpointer registered when the GstDataQueue was created.
 

+

+

+
Returns

+
 TRUE if the queue should be considered full.

+

+

+

+

+
GstDataQueueEmptyCallback ()

+
void
+(*GstDataQueueEmptyCallback) (GstDataQueue *queue,

+                    GstDataQueueEmptyCallback emptycallback,
+                    gpointer checkdata);

+
Creates a new GstDataQueue. If fullcallback
+ or emptycallback
+ are supplied, then
+the GstDataQueue will call the respective callback to signal full or empty condition.
+If the callbacks are NULL the GstDataQueue will instead emit 'full' and 'empty'
+signals.

checkfull
the callback used to tell if the element considers the queue full
+or not.
 
fullcallback
the callback which will be called when the queue is considered full.
 
emptycallback
the callback which will be called when the queue is considered empty.
 
checkdata
a gpointer that will be passed to the checkfull
+, fullcallback
+,
+and emptycallback
+callbacks.
 

+

+

+
Returns

gst_data_queue_push ()

+
gboolean
+gst_data_queue_push (GstDataQueue *queue,
+                     GstDataQueueItem *item);

+
Pushes a GstDataQueueItem (or a structure that begins with the same fields)
+on the queue
+. If the queue
+ is full, the call will block until space is
+available, OR the queue
+ is set to flushing state.
+MT safe.

+
Note that this function has slightly different semantics than gst_pad_push()
+and gst_pad_push_event(): this function only takes ownership of item
+ and
+the GstMiniObject contained in item
+ if the push was successful. If FALSE
+is returned, the caller is responsible for freeing item
+ and its contents.

+
+to be pushed anyway.
+MT safe.

+
Note that this function has slightly different semantics than gst_pad_push()

 GstFlowCombiner

+

+

+
Includes

+
#include <gst/base/gstflowcombiner.h>
+

+

+

+
Description

+
Utility struct to help handling GstFlowReturn combination. Useful for
+GstElements that have multiple source pads and need to combine
+the different GstFlowReturn for those pads.

+
GstFlowCombiner works by using the last GstFlowReturn for all GstPad
+it has in its list and computes the combined return value and provides
+it to the caller.

+
To add a new pad to the GstFlowCombiner use gst_flow_combiner_add_pad().
+The new GstPad is stored with a default value of GST_FLOW_OK.

+
In case you want a GstPad to be removed, use gst_flow_combiner_remove_pad().

+
Please be aware that this struct isn't thread safe as its designed to be
+ used by demuxers, those usually will have a single thread operating it.

+
These functions will take refs on the passed GstPads.

+
Aside from reducing the user's code size, the main advantage of using this
+helper struct is to follow the standard rules for GstFlowReturn combination.
+These rules are:

+

+
GST_FLOW_ERROR or below, GST_FLOW_NOT_NEGOTIATED and GST_FLOW_FLUSHING are
+returned immediatelly from the gst_flow_combiner_update_flow() function.

+

+

+
Functions

+

+
gst_flow_combiner_new ()

+
GstFlowCombiner *
+gst_flow_combiner_new (void);

+
Creates a new GstFlowCombiner, use gst_flow_combiner_free() to free it.

+

+
Returns

+
 A new GstFlowCombiner

+

+
Description

+
GstHarness is meant to make writing unit test for GStreamer much easier.
+It can be thought of as a way of treating a GstElement as a black box,
+deterministically feeding it data, and controlling what data it outputs.

+
The basic structure of GstHarness is two "floating" GstPads that connect
+to the harnessed GstElement src and sink GstPads like so:

+

+  
+    
+      
+        
+        
+      
+    
+

__________________________
+ _____   |  _____            _____  |   _____
+|     |  | |     |          |     | |  |     |
+| src |--+-| sink|  Element | src |-+--| sink|
+|_____|  | |_____|          |_____| |  |_____|
+         |__________________________|

+

+
+

+
With this, you can now simulate any environment the GstElement might find
+itself in. By specifying the GstCaps of the harness GstPads, using
+functions like gst_harness_set_src_caps() or gst_harness_set_sink_caps_str(),
+you can test how the GstElement interacts with different caps sets.

+
Your harnessed GstElement can of course also be a bin, and using
+gst_harness_new_parse() supporting standard gst-launch syntax, you can
+easily test a whole pipeline instead of just one element.

+
You can then go on to push GstBuffers and GstEvents on to the srcpad,
+using functions like gst_harness_push() and gst_harness_push_event(), and
+then pull them out to examine them with gst_harness_pull() and
+gst_harness_pull_event().

+

+
A simple buffer-in buffer-out example

#include <gst/gst.h>
+#include <gst/check/gstharness.h>
+GstHarness *h;
+GstBuffer *in_buf;
+GstBuffer *out_buf;
+
+// attach the harness to the src and sink pad of GstQueue
+h = gst_harness_new ("queue");
+
+// we must specify a caps before pushing buffers
+gst_harness_set_src_caps_str (h, "mycaps");
+
+// create a buffer of size 42
+in_buf = gst_harness_create_buffer (h, 42);
+
+// push the buffer into the queue
+gst_harness_push (h, in_buf);
+
+// pull the buffer from the queue
+out_buf = gst_harness_pull (h);
+
+// validate the buffer in is the same as buffer out
+fail_unless (in_buf == out_buf);
+
+// cleanup
+gst_buffer_unref (out_buf);
+gst_harness_teardown (h);

+

+
+

+
Another main feature of the GstHarness is its integration with the
+GstTestClock. Operating the GstTestClock can be very challenging, but
+GstHarness simplifies some of the most desired actions a lot, like wanting
+to manually advance the clock while at the same time releasing a GstClockID
+that is waiting, with functions like gst_harness_crank_single_clock_wait().

+
GstHarness also supports sub-harnesses, as a way of generating and
+validating data. A sub-harness is another GstHarness that is managed by
+the "parent" harness, and can either be created by using the standard
+gst_harness_new type functions directly on the (GstHarness *)->src_harness,
+or using the much more convenient gst_harness_add_src() or
+gst_harness_add_sink_parse(). If you have a decoder-element you want to test,
+(like vp8dec) it can be very useful to add a src-harness with both a
+src-element (videotestsrc) and an encoder (vp8enc) to feed the decoder data
+with different configurations, by simply doing:

+

+  
+    
+      
+        
+        
+      
+    
+  
1
+2
GstHarness * h = gst_harness_new (h, "vp8dec");
+gst_harness_add_src_parse (h, "videotestsrc is-live=1 ! vp8enc", TRUE);

+

+
+

+
and then feeding it data with:

+

+  
+    
+      
+        
+        
+      
+

gst_harness_crank_single_clock_wait ()

+
gboolean
+gst_harness_crank_single_clock_wait (GstHarness *h);

+
A "crank" consists of three steps:
+1: Wait for a GstClockID to be registered with the GstTestClock.
+2: Advance the GstTestClock to the time the GstClockID is waiting for.
+3: Release the GstClockID wait.
+Together, this provides an easy way to not have to think about the details
+around clocks and time, but still being able to write deterministic tests
+that are dependant on this. A "crank" can be though of as the notion of
+manually driving the clock forward to its next logical step.

+                                guint waits);

+
Similar to gst_harness_crank_single_clock_wait(), this is the function to use
+if your harnessed element(s) are using more then one gst_clock_id_wait.
+Failing to do so can (and will) make it racy which GstClockID you actually
+are releasing, where as this function will process all the waits at the
+same time, ensuring that one thread can't register another wait before
+both are released.

+flag set is concidered a src GstElement
+Non-src GstElements (like sinks and filters) are automatically set to
+playing by the GstHarness, but src GstElements are not to avoid them
+starting to produce buffers.
+Hence, for src GstElement you must call gst_harness_play() explicitly.

gst_harness_set_blocking_push_mode ()

+
void
+gst_harness_set_blocking_push_mode (GstHarness *h);

+
Setting this will make the harness block in the chain-function, and
+then release when gst_harness_pull() or gst_harness_try_pull() is called.
+Can be useful when wanting to control a src-element that is not implementing
+gst_clock_id_wait() so it can't be controlled by the GstTestClock, since
+it otherwise would produce buffers as fast as possible.

gst_harness_set_forwarding ()

+
void
+gst_harness_set_forwarding (GstHarness *h,
+                            gboolean forwarding);

+
As a convenience, a src-harness will forward GST_EVENT_STREAM_START,
+GST_EVENT_CAPS and GST_EVENT_SEGMENT to the main-harness if forwarding
+is enabled, and forward any sticky-events from the main-harness to
+the sink-harness. It will also forward the GST_QUERY_ALLOCATION.

+
If forwarding is disabled, the user will have to either manually push
+these events from the src-harness using gst_harness_src_push_event(), or
+create and push them manually. While this will allow full control and
+inspection of these events, for the most cases having forwarding enabled
+will be sufficient when writing a test where the src-harness' main function
+is providing data for the main-harness.

+
Forwarding is enabled by default.

+

+
gst_harness_add_src_harness ()

+
void
+gst_harness_add_src_harness (GstHarness *h,

+                             gboolean has_clock_wait);

+
A src-harness is a great way of providing the GstHarness with data.
+By adding a src-type GstElement, it is then easy to use functions like
+gst_harness_push_from_src or gst_harness_src_crank_and_push_many
+to provide your harnessed element with input. The has_clock_wait
+ variable
+is a greate way to control you src-element with, in that you can have it
+produce a buffer for you by simply cranking the clock, and not have it
+spin out of control producing buffers as fast as possible.

+
If a src-harness already exists it will be replaced.

+

+                           gboolean has_clock_wait);

+
Similar to gst_harness_add_src, this allows you to specify a launch-line,
+which can be useful for both having more then one GstElement acting as your
+src (Like a src producing raw buffers, and then an encoder, providing encoded
+data), but also by allowing you to set properties like "is-live" directly on
+the elements.

+
MT safe.

+                                     gint pushes);

+
Transfer data from the src-GstHarness to the main-GstHarness. Similar to
+gst_harness_push_from_src, this variant allows you to specify how many cranks
+and how many pushes to perform. This can be useful for both moving a lot
+of data at the same time, as well as cases when one crank does not equal one
+buffer to push and v.v.

+
Similar to what gst_harness_src_push does with GstBuffers, this transfers
+a GstEvent from the src-GstHarness to the main-GstHarness. Note that
+some GstEvents are being transferred automagically. Look at sink_forward_pad
+for details.

+
MT safe.

+

+
Parameters

void
+gst_harness_add_sink_harness (GstHarness *h,
+                              GstHarness *sink_harness);

+
Similar to gst_harness_add_src, this allows you to send the data coming out
+of your harnessed GstElement to a sink-element, allowing to test different
+responses the element output might create in sink elements. An example might
+be an existing sink providing some analytical data on the input it receives that
+can be useful to your testing. If the goal is to test a sink-element itself,
+this is better acheived using gst_harness_new directly on the sink.

+
If a sink-harness already exists it will be replaced.

+offsets. If this function returns GST_FLOW_OK, the result buffer will be
+stored in buffer
+. The  contents of buffer
+ is invalid for any other
+return value.

[allow-none]
offset
the offset of the range
 
length
the length of the range
 
buffer
a memory location to hold the result buffer.

+                                GstTypeFindProbability *prob);

+
Utility function to do pull-based typefinding. Unlike gst_type_find_helper()
+however, this function will use the specified function func
+ to obtain the
+data needed by the typefind functions, rather than operating on a given
+source pad. This is useful mostly for elements like tag demuxers which
+strip off data at the beginning and/or end of a file and want to typefind
+the stripped data stream before adding their own source pad (the specified
+callback can then call the upstream peer pad with offsets adjusted for the
+tag size, for example).

+
When extension
+ is not NULL, this function will first try the typefind
+functions for the given extension, which might speed up the typefinding
+in many cases.

+
Free-function: gst_caps_unref

Description

+
Concatenates streams together to one continous stream.

+
All streams but the current one are blocked until the current one
+finished with GST_EVENT_EOS. Then the next stream is enabled, while
+keeping the running time continous for GST_FORMAT_TIME segments or
+keeping the segment continous for GST_FORMAT_BYTES segments.

+
Streams are switched in the order in which the sinkpads were requested.

+
By default, the stream segment's base values are adjusted to ensure
+the segment transitions between streams are continuous. In some cases,
+it may be desirable to turn off these adjustments (for example, because
+another downstream element like a streamsynchronizer adjusts the base
+values on its own). The adjust-base property can be used for this purpose.

+

+
Description

+
The downloadbuffer element provides on-disk buffering and caching of, typically,
+a network file. temp-template should be set to a value such as
+/tmp/gstreamer-XXXXXX and the element will allocate a random free filename and
+buffer the data in the file.

+
With max-size-bytes and max-size-time you can configure the buffering limits.
+The downloadbuffer element will try to read-ahead these amounts of data. When
+the amount of read-ahead data drops below low-percent of the configured max,
+the element will start emitting BUFFERING messages until high-percent of max is
+reached again.

+
The downloadbuffer provides push and pull based scheduling on its source pad
+and will efficiently seek in the upstream element when needed.

+
The temp-location property will be used to notify the application of the
+allocated filename.

+
When the downloadbuffer has completely downloaded the media, it will
+post an application message named  "GstCacheDownloadComplete"
+with the following information:

+
*
+  G_TYPE_STRING

+"location":
+
  the location of the completely downloaded file.

It is mostly used as a testing element, one trivial example for testing
+basic GStreamer core functionality is:

+

+
Example launch line

+

gst-launch-1.0 -v fakesrc num-buffers=5 ! fakesink

+

+
+
 This pipeline will push 5 empty buffers to the fakesink element and then
+sends an EOS.

Description

+
Read data from a unix file descriptor.

+
To generate data, enter some data on the console followed by enter.
+The above mentioned pipeline should dump data packets to the console.

+
If the “timeout” property is set to a value bigger than 0, fdsrc will
+generate an element message named "GstFdSrcTimeout"
+if no data was received in the given timeout.

+
The message's structure contains one field:

+
  • guint64 timeout: the timeout in microseconds that
+expired when waiting for data.

+

+

Description

+
Direct one out of N input streams to the output pad.

+
The input pads are from a GstPad subclass and have additional
+properties, which users may find useful, namely:

+
    
+
  • "running-time": Running time of stream on pad (gint64)
    • 
+
  • "tags": The currently active tags on the pad (GstTagList, boxed type)
    • 
+
  • "active": If the pad is currently active (gboolean)
    • 
+
  • "always-ok" : Make an inactive pads return GST_FLOW_OK instead of
+GST_FLOW_NOT_LINKED
    •

GST_INPUT_SELECTOR_SYNC_MODE_ACTIVE_SEGMENT

+
Sync using the current active segment.

+		 
GST_INPUT_SELECTOR_SYNC_MODE_CLOCK

+
Sync using the clock.

+		 

+

+

+

+

+
Property Details

+

+
The “active-pad” property

+
  “active-pad”               GstPad *

+
The currently active sink pad.

+
Flags: Read / Write

+

+

+

+
The “cache-buffers” property

+
  “cache-buffers”            gboolean

+
If set to TRUE and GstInputSelector:sync-streams is also set to TRUE,
+the active pad will cache the buffers still considered valid (after current
+running time, see sync-mode) to avoid missing frames if/when the pad is
+reactivated.

+
The active pad may push more buffers than what is currently displayed/consumed
+and when changing pads those buffers will be discarded and the only way to
+reactivate that pad without loosing the already consumed buffers is to enable cache.

+
Flags: Read / Write

+
Default value: FALSE

+

+

+

+
The “n-pads” property

+
  “n-pads”                   guint

+
The number of sink pads.

+
Flags: Read

+
Default value: 0

+

+

+

+
The “sync-mode” property

+
  “sync-mode”                GstInputSelectorSyncMode

+
Select how input-selector will sync buffers when in sync-streams mode.

+
Note that when using the "active-segment" mode, the "active-segment" may
+be ahead of current clock time when switching the active pad, as the current
+active pad may have pushed more buffers than what was displayed/consumed,
+which may cause delays and some missing buffers.

+
Flags: Read / Write

+
Default value: Sync using the current active segment

+

+

+

+
The “sync-streams” property

+
  “sync-streams”             gboolean

+
If set to TRUE all inactive streams will be synced to the
+running time of the active stream or to the current clock.

+
To make sure no buffers are dropped by input-selector
+that might be needed when switching the active pad,
+sync-mode should be set to "clock" and cache-buffers to TRUE.

+
Flags: Read / Write

+
Default value: TRUE

+

+
Description

+
Multiqueue is similar to a normal GstQueue with the following additional
+features:

+
1) Multiple streamhandling

+
  • The element handles queueing data on more than one stream at once. To
+achieve such a feature it has request sink pads (sinku) and
+'sometimes' src pads (srcu). When requesting a given sinkpad with gst_element_request_pad(),
+the associated srcpad for that stream will be created.
+Example: requesting sink1 will generate src1.

+
2) Non-starvation on multiple stream

+
  • If more than one stream is used with the element, the streams' queues
+will be dynamically grown (up to a limit), in order to ensure that no
+stream is risking data starvation. This guarantees that at any given
+time there are at least N bytes queued and available for each individual
+stream. If an EOS event comes through a srcpad, the associated queue will be
+considered as 'not-empty' in the queue-size-growing algorithm.

+
3) Non-linked srcpads graceful handling

+
  • In order to better support dynamic switching between streams, the multiqueue
+(unlike the current GStreamer queue) continues to push buffers on non-linked
+pads rather than shutting down. In addition, to prevent a non-linked stream from very quickly consuming all
+available buffers and thus 'racing ahead' of the other streams, the element
+must ensure that buffers and inlined events for a non-linked stream are pushed
+in the same order as they were received, relative to the other streams
+controlled by the element. This means that a buffer cannot be pushed to a
+non-linked pad any sooner than buffers in any other stream which were received
+before it.

+
Data is queued until one of the limits specified by the
+“max-size-buffers”, “max-size-bytes” and/or
+“max-size-time” properties has been reached. Any attempt to push
+more buffers into the queue will block the pushing thread until more space
+becomes available. “extra-size-buffers”,

+
“extra-size-bytes” and “extra-size-time” are
+currently unused.

+
The default queue size limits are 5 buffers, 10MB of data, or
+two second worth of data, whichever is reached first. Note that the number
+of buffers will dynamically grow depending on the fill level of
+other queues.

+
The “underrun” signal is emitted when all of the queues
+are empty. The “overrun” signal is emitted when one of the
+queues is filled.
+Both signals are emitted from the context of the streaming thread.

+
When using “sync-by-running-time” the unlinked streams will
+be throttled by the highest running-time of linked streams. This allows
+further relinking of those unlinked streams without them being in the
+future (i.e. to achieve gapless playback).
+When dealing with streams which have got different consumption requirements
+downstream (ex: video decoders which will consume more buffer (in time) than
+audio decoders), it is recommended to group streams of the same type
+by using the pad "group-id" property. This will further throttle streams
+in time within that group.

Reports that one of the queues in the multiqueue is full (overrun).
+A queue is full if the total amount of data inside it (num-buffers, time,
+size) is higher than the boundary values which can be set through the
+GObject properties.

+
This can be used as an indicator of pre-roll.

+

+
Parameters

The “underrun” signal

+
void
+user_function (GstMultiQueue *multiqueue,
+               gpointer       user_data)

+
This signal is emitted from the streaming thread when there is
+no data in any of the queues inside the multiqueue instance (underrun).

+
This indicates either starvation or EOS from the upstream data sources.

+

Description

+
Data is queued until one of the limits specified by the
+“max-size-buffers”, “max-size-bytes” and/or
+“max-size-time” properties has been reached. Any attempt to push
+more buffers into the queue will block the pushing thread until more space
+becomes available.

+
The queue will create a new thread on the source pad to decouple the
+processing on sink and source pad.

+
You can query how many buffers are queued by reading the
+“current-level-buffers” property. You can track changes
+by connecting to the notify::current-level-buffers signal (which
+like all signals will be emitted from the streaming thread). The same
+applies to the “current-level-time” and
+“current-level-bytes” properties.

+
The default queue size limits are 200 buffers, 10MB of data, or
+one second worth of data, whichever is reached first.

+
As said earlier, the queue blocks by default when one of the specified
+maximums (bytes, time, buffers) has been reached. You can set the
+“leaky” property to specify that instead of blocking it should
+leak (drop) new or old buffers.

+
The “underrun” signal is emitted when the queue has less data than
+the specified minimum thresholds require (by default: when the queue is
+empty). The “overrun” signal is emitted when the queue is filled
+up. Both signals are emitted from the context of the streaming thread.

GST_QUEUE_NO_LEAK

+
Not Leaky

+		 
GST_QUEUE_LEAK_UPSTREAM

+
Leaky on upstream (new buffers)

+		 
GST_QUEUE_LEAK_DOWNSTREAM

+
Leaky on downstream (old buffers)

+		 

+

+

+

+

+
Property Details

+

+
The “current-level-buffers” property

+
  “current-level-buffers”    guint

+
Current number of buffers in the queue.

+
Flags: Read

+
Default value: 0

+

+

+

+
The “current-level-bytes” property

+
  “current-level-bytes”      guint

+
Current amount of data in the queue (bytes).

+
Flags: Read

+
Default value: 0

+

+

+

+
The “current-level-time” property

+
  “current-level-time”       guint64

+
The “flush-on-eos” property

+
  “flush-on-eos”             gboolean

+
Discard all data in the queue when an EOS event is received, and pass
+on the EOS event as soon as possible (instead of waiting until all
+buffers in the queue have been processed, which is the default behaviour).

+
Flushing the queue on EOS might be useful when capturing and encoding
+from a live source, to finish up the recording quickly in cases when
+the encoder is slow. Note that this might mean some data from the end of
+the recording data might be lost though (never more than the configured
+max. sizes though).

Description

+
Data is queued until one of the limits specified by the
+“max-size-buffers”, “max-size-bytes” and/or
+“max-size-time” properties has been reached. Any attempt to push
+more buffers into the queue will block the pushing thread until more space
+becomes available.

+
The queue will create a new thread on the source pad to decouple the
+processing on sink and source pad.

+
You can query how many buffers are queued by reading the
+“current-level-buffers” property.

+
The default queue size limits are 100 buffers, 2MB of data, or
+two seconds worth of data, whichever is reached first.

+
If you set temp-template to a value such as /tmp/gstreamer-XXXXXX, the element
+will allocate a random free filename and buffer data in the file.
+By using this, it will buffer the entire stream data on the file independently
+of the queue size limits, they will only be used for buffering statistics.

+
The temp-location property will be used to notify the application of the
+allocated filename.

Description

+
The basic concept was started from de-funneling element which restores one
+serialized stream via GstFunnel to its original state. GstStreamidDemux
+classifies each stream base on stream ids.

+
The stream id demux always takes one input and checks how many streams
+are contained in a stream by STREAM_START event. Likewise GstFunnel,
+GstStreamidDemux does not synchronize the different output streams.

+
“active-pad” provides information about which output pad
+is activated at the moment.

Description

+
Split data to multiple pads. Branching the data flow is useful when e.g.
+capturing a video where the video is shown on the screen and also encoded and
+written to a file. Another example is playing music and hooking up a
+visualisation module.

+
One needs to use separate queue elements (or a multiqueue) in each branch to
+provide separate threads for each branch. Otherwise a blocked dataflow in one
+branch would stall the other branches.

+

+

+
+

+
Play song.ogg audio file which must be in the current working directory
+and render visualisations using the goom element (this can be easier done
+using the playbin element, this is just an example pipeline).

Description

+
Determines the media-type of a stream. It applies typefind functions in the
+order of their rank. Once the type has been detected it sets its src pad caps
+to the found media type.

+
Whenever a type is found the “have-type” signal is
+emitted, either from the streaming thread or the application thread
+(the latter may happen when typefinding is done pull-based from the
+state change function).

+
Plugins can register custom typefinders by using GstTypeFindFactory.

+ * @title: GStreamer
+ * @short_description: Media library supporting arbitrary formats and filter
+ *                     graphs.
+ *
+ * GStreamer is a framework for constructing graphs of various filters
+ * (termed elements here) that will handle streaming media.  Any discrete
+ * (packetizable) media type is supported, with provisions for automatically
+ * determining source type.  Formatting/framing information is provided with
+ * a powerful negotiation framework.  Plugins are heavily used to provide for
+ * all elements, allowing one to construct plugins outside of the GST
+ * library, even released binary-only if license require (please don't).
+ * GStreamer covers a wide range of use cases including: playback, recording,
+ * editing, serving streams, voice over ip and video calls.
+ *
+ * The GStreamer library should be initialized with
+ * gst_init() before it can be used. You should pass pointers to the main argc
+ * and argv variables so that GStreamer can process its own command line
+ * options, as shown in the following example.
+ *
+ * ## Initializing the gstreamer library
+ *
+ * |[ 
+ * int
+ * main (int argc, char *argv[])
+ * {
+ *   // initialize the GStreamer library
+ *   gst_init (&argc, &argv);
+ *   ...
+ * }
+ * ]|
+ *
+ * It's allowed to pass two %NULL pointers to gst_init() in case you don't want
+ * to pass the command line args to GStreamer.
+ *
+ * You can also use GOption to initialize your own parameters as shown in
+ * the next code fragment:
+ *
+ * ## Initializing own parameters when initializing gstreamer
+ * |[ 
+ * static gboolean stats = FALSE;
+ * ...
+ * int
+ * main (int argc, char *argv[])
+ * {
+ *  GOptionEntry options[] = {
+ *   {"tags", 't', 0, G_OPTION_ARG_NONE, &tags,
+ *       N_("Output tags (also known as metadata)"), NULL},
+ *   {NULL}
+ *  };
+ *  ctx = g_option_context_new ("[ADDITIONAL ARGUMENTS]");
+ *  g_option_context_add_main_entries (ctx, options, GETTEXT_PACKAGE);
+ *  g_option_context_add_group (ctx, gst_init_get_option_group ());
+ *  if (!g_option_context_parse (ctx, &argc, &argv, &err)) {
+ *    g_print ("Error initializing: %s\n", GST_STR_NULL (err->message));
+ *    exit (1);
+ *  }
+ *  g_option_context_free (ctx);
+ * ...
+ * }
+ * ]|
+ *
+ * Use gst_version() to query the library version at runtime or use the
+ * GST_VERSION_* macros to find the version at compile time. Optionally
+ * gst_version_string() returns a printable string.
+ *
+ * The gst_deinit() call is used to clean up all internal resources used
+ * by GStreamer. It is mostly used in unit tests to check for leaks.

+ *
+ * Memory is usually created by allocators with a gst_allocator_alloc()
+ * method call. When %NULL is used as the allocator, the default allocator will
+ * be used.
+ *
+ * New allocators can be registered with gst_allocator_register().
+ * Allocators are identified by name and can be retrieved with
+ * gst_allocator_find(). gst_allocator_set_default() can be used to change the
+ * default allocator.
+ *
+ * New memory can be created with gst_memory_new_wrapped() that wraps the memory
+ * allocated elsewhere.

+/**
+ * SECTION:gstbin
+ * @title: GstBin
+ * @short_description: Base class and element that can contain other elements
+ *
+ * #GstBin is an element that can contain other #GstElement, allowing them to be
+ * managed as a group.
+ * Pads from the child elements can be ghosted to the bin, see #GstGhostPad.
+ * This makes the bin look like any other elements and enables creation of
+ * higher-level abstraction elements.
+ *
+ * A new #GstBin is created with gst_bin_new(). Use a #GstPipeline instead if you
+ * want to create a toplevel bin because a normal bin doesn't have a bus or
+ * handle clock distribution of its own.
+ *
+ * After the bin has been created you will typically add elements to it with
+ * gst_bin_add(). You can remove elements with gst_bin_remove().
+ *
+ * An element can be retrieved from a bin with gst_bin_get_by_name(), using the
+ * elements name. gst_bin_get_by_name_recurse_up() is mainly used for internal
+ * purposes and will query the parent bins when the element is not found in the
+ * current bin.
+ *
+ * An iterator of elements in a bin can be retrieved with
+ * gst_bin_iterate_elements(). Various other iterators exist to retrieve the
+ * elements in a bin.
+ *
+ * gst_object_unref() is used to drop your reference to the bin.
+ *
+ * The #GstBin::element-added signal is fired whenever a new element is added to
+ * the bin. Likewise the #GstBin::element-removed signal is fired whenever an
+ * element is removed from the bin.
+ *
+ * ## Notes
+ *
+ * A #GstBin internally intercepts every #GstMessage posted by its children and
+ * implements the following default behaviour for each of them:
+ *
+ * * GST_MESSAGE_EOS: This message is only posted by sinks in the PLAYING
+ * state. If all sinks posted the EOS message, this bin will post and EOS
+ * message upwards.
+ *
+ * * GST_MESSAGE_SEGMENT_START: Just collected and never forwarded upwards.
+ * The messages are used to decide when all elements have completed playback
+ * of their segment.
+ *
+ * * GST_MESSAGE_SEGMENT_DONE: Is posted by #GstBin when all elements that posted
+ * a SEGMENT_START have posted a SEGMENT_DONE.
+ *
+ * * GST_MESSAGE_DURATION_CHANGED: Is posted by an element that detected a change
+ * in the stream duration. The default bin behaviour is to clear any
+ * cached duration values so that the next duration query will perform
+ * a full duration recalculation. The duration change is posted to the
+ * application so that it can refetch the new duration with a duration
+ * query. Note that these messages can be posted before the bin is
+ * prerolled, in which case the duration query might fail.
+ *
+ * * GST_MESSAGE_CLOCK_LOST: This message is posted by an element when it
+ * can no longer provide a clock. The default bin behaviour is to
+ * check if the lost clock was the one provided by the bin. If so and
+ * the bin is currently in the PLAYING state, the message is forwarded to
+ * the bin parent.
+ * This message is also generated when a clock provider is removed from
+ * the bin. If this message is received by the application, it should
+ * PAUSE the pipeline and set it back to PLAYING to force a new clock
+ * distribution.
+ *
+ * * GST_MESSAGE_CLOCK_PROVIDE: This message is generated when an element
+ * can provide a clock. This mostly happens when a new clock
+ * provider is added to the bin. The default behaviour of the bin is to
+ * mark the currently selected clock as dirty, which will perform a clock
+ * recalculation the next time the bin is asked to provide a clock.
+ * This message is never sent tot the application but is forwarded to
+ * the parent of the bin.
+ *
+ * * OTHERS: posted upwards.
+ *
+ * A #GstBin implements the following default behaviour for answering to a
+ * #GstQuery:
+ *
+ * * GST_QUERY_DURATION:If the query has been asked before with the same format
+ * and the bin is a toplevel bin (ie. has no parent),
+ * use the cached previous value. If no previous value was cached, the
+ * query is sent to all sink elements in the bin and the MAXIMUM of all
+ * values is returned. If the bin is a toplevel bin the value is cached.
+ * If no sinks are available in the bin, the query fails.
+ *
+ * * GST_QUERY_POSITION:The query is sent to all sink elements in the bin and the
+ * MAXIMUM of all values is returned. If no sinks are available in the bin,
+ * the query fails.
+ *
+ * * OTHERS:the query is forwarded to all sink elements, the result
+ * of the first sink that answers the query successfully is returned. If no
+ * sink is in the bin, the query fails.
+ *
+ * A #GstBin will by default forward any event sent to it to all sink
+ * (#GST_EVENT_TYPE_DOWNSTREAM) or source (#GST_EVENT_TYPE_UPSTREAM) elements
+ * depending on the event type.
+ * If all the elements return %TRUE, the bin will also return %TRUE, else %FALSE
+ * is returned. If no elements of the required type are in the bin, the event
+ * handler will return %TRUE.

+ *     PAUSE the pipeline and set it back to PLAYING to force a new clock
+ *     and a new base_time distribution.

+ * GST_MESSAGE_CLOCK_PROVIDE: This message is generated when an element

+ *
+ * GST_MESSAGE_ASYNC_START: Create an internal ELEMENT message that stores

+ *     new base_time. This message is not forwarded to the application.
+ *
+ * GST_MESSAGE_ASYNC_DONE: Find the internal ELEMENT message we kept for the

+/**
+ * SECTION:gstbuffer
+ * @title: GstBuffer
+ * @short_description: Data-passing buffer type
+ * @see_also: #GstPad, #GstMiniObject, #GstMemory, #GstMeta, #GstBufferPool
+ *
+ * Buffers are the basic unit of data transfer in GStreamer. They contain the
+ * timing and offset along with other arbitrary metadata that is associated
+ * with the #GstMemory blocks that the buffer contains.
+ *
+ * Buffers are usually created with gst_buffer_new(). After a buffer has been
+ * created one will typically allocate memory for it and add it to the buffer.
+ * The following example creates a buffer that can hold a given video frame
+ * with a given width, height and bits per plane.
+ * |[
+ *   GstBuffer *buffer;
+ *   GstMemory *memory;
+ *   gint size, width, height, bpp;
+ *   ...
+ *   size = width * height * bpp;
+ *   buffer = gst_buffer_new ();
+ *   memory = gst_allocator_alloc (NULL, size, NULL);
+ *   gst_buffer_insert_memory (buffer, -1, memory);
+ *   ...
+ * ]|
+ *
+ * Alternatively, use gst_buffer_new_allocate() to create a buffer with
+ * preallocated data of a given size.
+ *
+ * Buffers can contain a list of #GstMemory objects. You can retrieve how many
+ * memory objects with gst_buffer_n_memory() and you can get a pointer
+ * to memory with gst_buffer_peek_memory()
+ *
+ * A buffer will usually have timestamps, and a duration, but neither of these
+ * are guaranteed (they may be set to #GST_CLOCK_TIME_NONE). Whenever a
+ * meaningful value can be given for these, they should be set. The timestamps
+ * and duration are measured in nanoseconds (they are #GstClockTime values).
+ *
+ * The buffer DTS refers to the timestamp when the buffer should be decoded and
+ * is usually monotonically increasing. The buffer PTS refers to the timestamp when
+ * the buffer content should be presented to the user and is not always
+ * monotonically increasing.
+ *
+ * A buffer can also have one or both of a start and an end offset. These are
+ * media-type specific. For video buffers, the start offset will generally be
+ * the frame number. For audio buffers, it will be the number of samples
+ * produced so far. For compressed data, it could be the byte offset in a
+ * source or destination file. Likewise, the end offset will be the offset of
+ * the end of the buffer. These can only be meaningfully interpreted if you
+ * know the media type of the buffer (the preceding CAPS event). Either or both
+ * can be set to #GST_BUFFER_OFFSET_NONE.
+ *
+ * gst_buffer_ref() is used to increase the refcount of a buffer. This must be
+ * done when you want to keep a handle to the buffer after pushing it to the
+ * next element. The buffer refcount determines the writability of the buffer, a
+ * buffer is only writable when the refcount is exactly 1, i.e. when the caller
+ * has the only reference to the buffer.
+ *
+ * To efficiently create a smaller buffer out of an existing one, you can
+ * use gst_buffer_copy_region(). This method tries to share the memory objects
+ * between the two buffers.
+ *
+ * If a plug-in wants to modify the buffer data or metadata in-place, it should
+ * first obtain a buffer that is safe to modify by using
+ * gst_buffer_make_writable().  This function is optimized so that a copy will
+ * only be made when it is necessary.
+ *
+ * Several flags of the buffer can be set and unset with the
+ * GST_BUFFER_FLAG_SET() and GST_BUFFER_FLAG_UNSET() macros. Use
+ * GST_BUFFER_FLAG_IS_SET() to test if a certain #GstBufferFlags flag is set.
+ *
+ * Buffers can be efficiently merged into a larger buffer with
+ * gst_buffer_append(). Copying of memory will only be done when absolutely
+ * needed.
+ *
+ * Arbitrary extra metadata can be set on a buffer with gst_buffer_add_meta().
+ * Metadata can be retrieved with gst_buffer_get_meta(). See also #GstMeta
+ *
+ * An element should either unref the buffer or push it out on a src pad
+ * using gst_pad_push() (see #GstPad).
+ *
+ * Buffers are usually freed by unreffing them with gst_buffer_unref(). When
+ * the refcount drops to 0, any memory and metadata pointed to by the buffer is
+ * unreffed as well. Buffers allocated from a #GstBufferPool will be returned to
+ * the pool when the refcount drops to 0.
+ *
+ * The #GstParentBufferMeta is a meta which can be attached to a #GstBuffer
+ * to hold a reference to another buffer that is only released when the child
+ * #GstBuffer is released.
+ *
+ * Typically, #GstParentBufferMeta is used when the child buffer is directly
+ * using the #GstMemory of the parent buffer, and wants to prevent the parent
+ * buffer from being returned to a buffer pool until the #GstMemory is available
+ * for re-use. (Since 1.6)

+ * SECTION:gstbufferpool
+ * @title: GstBufferPool
+ * @short_description: Pool for buffers
+ * @see_also: #GstBuffer
+ *
+ * A #GstBufferPool is an object that can be used to pre-allocate and recycle
+ * buffers of the same size and with the same properties.
+ *
+ * A #GstBufferPool is created with gst_buffer_pool_new().
+ *
+ * Once a pool is created, it needs to be configured. A call to
+ * gst_buffer_pool_get_config() returns the current configuration structure from
+ * the pool. With gst_buffer_pool_config_set_params() and
+ * gst_buffer_pool_config_set_allocator() the bufferpool parameters and
+ * allocator can be configured. Other properties can be configured in the pool
+ * depending on the pool implementation.
+ *
+ * A bufferpool can have extra options that can be enabled with
+ * gst_buffer_pool_config_add_option(). The available options can be retrieved
+ * with gst_buffer_pool_get_options(). Some options allow for additional
+ * configuration properties to be set.
+ *
+ * After the configuration structure has been configured,
+ * gst_buffer_pool_set_config() updates the configuration in the pool. This can
+ * fail when the configuration structure is not accepted.
+ *
+ * After the a pool has been configured, it can be activated with
+ * gst_buffer_pool_set_active(). This will preallocate the configured resources
+ * in the pool.
+ *
+ * When the pool is active, gst_buffer_pool_acquire_buffer() can be used to
+ * retrieve a buffer from the pool.
+ *
+ * Buffers allocated from a bufferpool will automatically be returned to the
+ * pool with gst_buffer_pool_release_buffer() when their refcount drops to 0.
+ *
+ * The bufferpool can be deactivated again with gst_buffer_pool_set_active().
+ * All further gst_buffer_pool_acquire_buffer() calls will return an error. When
+ * all buffers are returned to the pool they will be freed.
+ *
+ * Use gst_object_unref() to release the reference to a bufferpool. If the
+ * refcount of the pool reaches 0, the pool will be freed.

+/**
+ * SECTION:gstbus
+ * @title: GstBus
+ * @short_description: Asynchronous message bus subsystem
+ * @see_also: #GstMessage, #GstElement
+ *
+ * The #GstBus is an object responsible for delivering #GstMessage packets in
+ * a first-in first-out way from the streaming threads (see #GstTask) to the
+ * application.
+ *
+ * Since the application typically only wants to deal with delivery of these
+ * messages from one thread, the GstBus will marshall the messages between
+ * different threads. This is important since the actual streaming of media
+ * is done in another thread than the application.
+ *
+ * The GstBus provides support for #GSource based notifications. This makes it
+ * possible to handle the delivery in the glib mainloop.
+ *
+ * The #GSource callback function gst_bus_async_signal_func() can be used to
+ * convert all bus messages into signal emissions.
+ *
+ * A message is posted on the bus with the gst_bus_post() method. With the
+ * gst_bus_peek() and gst_bus_pop() methods one can look at or retrieve a
+ * previously posted message.
+ *
+ * The bus can be polled with the gst_bus_poll() method. This methods blocks
+ * up to the specified timeout value until one of the specified messages types
+ * is posted on the bus. The application can then gst_bus_pop() the messages
+ * from the bus to handle them.
+ * Alternatively the application can register an asynchronous bus function
+ * using gst_bus_add_watch_full() or gst_bus_add_watch(). This function will
+ * install a #GSource in the default glib main loop and will deliver messages
+ * a short while after they have been posted. Note that the main loop should
+ * be running for the asynchronous callbacks.
+ *
+ * It is also possible to get messages from the bus without any thread
+ * marshalling with the gst_bus_set_sync_handler() method. This makes it
+ * possible to react to a message in the same thread that posted the
+ * message on the bus. This should only be used if the application is able
+ * to deal with messages from different threads.
+ *
+ * Every #GstPipeline has one bus.
+ *
+ * Note that a #GstPipeline will set its bus into flushing state when changing
+ * from READY to NULL state.

+ * gst_bus_poll:
+ * @bus: a #GstBus
+ * @events: a mask of #GstMessageType, representing the set of message types to
+ * poll for (note special handling of extended message types below)
+ * @timeout: the poll timeout, as a #GstClockTime, or #GST_CLOCK_TIME_NONE to poll
+ * indefinitely.
+ *
+ * Poll the bus for messages. Will block while waiting for messages to come.
+ * You can specify a maximum time to poll with the @timeout parameter. If
+ * @timeout is negative, this function will block indefinitely.
+ *
+ * All messages not in @events will be popped off the bus and will be ignored.
+ * It is not possible to use message enums beyond #GST_MESSAGE_EXTENDED in the
+ * @events mask
+ *
+ * Because poll is implemented using the "message" signal enabled by
+ * gst_bus_add_signal_watch(), calling gst_bus_poll() will cause the "message"
+ * signal to be emitted for every message that poll sees. Thus a "message"
+ * signal handler will see the same messages that this function sees -- neither
+ * will steal messages from the other.
+ *
+ * This function will run a main loop from the default main context when
+ * polling.
+ *
+ * You should never use this function, since it is pure evil. This is
+ * especially true for GUI applications based on Gtk+ or Qt, but also for any
+ * other non-trivial application that uses the GLib main loop. As this function
+ * runs a GLib main loop, any callback attached to the default GLib main
+ * context may be invoked. This could be timeouts, GUI events, I/O events etc.;
+ * even if gst_bus_poll() is called with a 0 timeout. Any of these callbacks
+ * may do things you do not expect, e.g. destroy the main application window or
+ * some other resource; change other application state; display a dialog and
+ * run another main loop until the user clicks it away. In short, using this
+ * function may add a lot of complexity to your code through unexpected
+ * re-entrancy and unexpected changes to your application's state.
+ *
+ * For 0 timeouts use gst_bus_pop_filtered() instead of this function; for
+ * other short timeouts use gst_bus_timed_pop_filtered(); everything else is
+ * better handled by setting up an asynchronous bus watch and doing things
+ * from there.
+ *
+ * Returns: (transfer full) (nullable): the message that was received,
+ *     or %NULL if the poll timed out. The message is taken from the
+ *     bus and needs to be unreffed with gst_message_unref() after
+ *     usage.

+/**
+ * SECTION:gstcaps
+ * @title: GstCaps
+ * @short_description: Structure describing sets of media formats
+ * @see_also: #GstStructure, #GstMiniObject
+ *
+ * Caps (capabilities) are lightweight refcounted objects describing media types.
+ * They are composed of an array of #GstStructure.
+ *
+ * Caps are exposed on #GstPadTemplate to describe all possible types a
+ * given pad can handle. They are also stored in the #GstRegistry along with
+ * a description of the #GstElement.
+ *
+ * Caps are exposed on the element pads using the gst_pad_query_caps() pad
+ * function. This function describes the possible types that the pad can
+ * handle or produce at runtime.
+ *
+ * A #GstCaps can be constructed with the following code fragment:
+ * |[
+ *   GstCaps *caps = gst_caps_new_simple ("video/x-raw",
+ *      "format", G_TYPE_STRING, "I420",
+ *      "framerate", GST_TYPE_FRACTION, 25, 1,
+ *      "pixel-aspect-ratio", GST_TYPE_FRACTION, 1, 1,
+ *      "width", G_TYPE_INT, 320,
+ *      "height", G_TYPE_INT, 240,
+ *      NULL);
+ * ]|
+ *
+ * A #GstCaps is fixed when it has no properties with ranges or lists. Use
+ * gst_caps_is_fixed() to test for fixed caps. Fixed caps can be used in a
+ * caps event to notify downstream elements of the current media type.
+ *
+ * Various methods exist to work with the media types such as subtracting
+ * or intersecting.
+ *
+ * Be aware that the current #GstCaps / #GstStructure serialization into string
+ * has limited support for nested #GstCaps / #GstStructure fields. It can only
+ * support one level of nesting. Using more levels will lead to unexpected
+ * behavior when using serialization features, such as gst_caps_to_string() or
+ * gst_value_serialize() and their counterparts.

+ * SECTION:gstcapsfeatures
+ * @title: GstCapsFeatures
+ * @short_description: A set of features in caps
+ * @see_also: #GstCaps
+ *
+ * #GstCapsFeatures can optionally be set on a #GstCaps to add requirements
+ * for additional features for a specific #GstStructure. Caps structures with
+ * the same name but with a non-equal set of caps features are not compatible.
+ * If a pad supports multiple sets of features it has to add multiple equal
+ * structures with different feature sets to the caps.
+ *
+ * Empty #GstCapsFeatures are equivalent with the #GstCapsFeatures that only
+ * contain #GST_CAPS_FEATURE_MEMORY_SYSTEM_MEMORY. ANY #GstCapsFeatures as
+ * created by gst_caps_features_new_any() are equal to any other #GstCapsFeatures
+ * and can be used to specify that any #GstCapsFeatures would be supported, e.g.
+ * for elements that don't touch buffer memory. #GstCaps with ANY #GstCapsFeatures
+ * are considered non-fixed and during negotiation some #GstCapsFeatures have
+ * to be selected.
+ *
+ * Examples for caps features would be the requirement of a specific #GstMemory
+ * types or the requirement of having a specific #GstMeta on the buffer. Features
+ * are given as a string of the format "memory:GstMemoryTypeName" or
+ * "meta:GstMetaAPIName".
+ *
+ * Since: 1.2

+ * @see_also: #GstBin
+ *
+ * This interface abstracts handling of property sets for elements with
+ * children. Imagine elements such as mixers or polyphonic generators. They all
+ * have multiple #GstPad or some kind of voice objects. Another use case are
+ * container elements like #GstBin.
+ * The element implementing the interface acts as a parent for those child
+ * objects.
+ *
+ * By implementing this interface the child properties can be accessed from the
+ * parent element by using gst_child_proxy_get() and gst_child_proxy_set().
+ *
+ * Property names are written as "child-name::property-name". The whole naming
+ * scheme is recursive. Thus "child1::child2::property" is valid too, if
+ * "child1" and "child2" implement the #GstChildProxy interface.

+ * SECTION:gstclock
+ * @title: GstClock
+ * @short_description: Abstract class for global clocks
+ * @see_also: #GstSystemClock, #GstPipeline
+ *
+ * GStreamer uses a global clock to synchronize the plugins in a pipeline.
+ * Different clock implementations are possible by implementing this abstract
+ * base class or, more conveniently, by subclassing #GstSystemClock.
+ *
+ * The #GstClock returns a monotonically increasing time with the method
+ * gst_clock_get_time(). Its accuracy and base time depend on the specific
+ * clock implementation but time is always expressed in nanoseconds. Since the
+ * baseline of the clock is undefined, the clock time returned is not
+ * meaningful in itself, what matters are the deltas between two clock times.
+ * The time returned by a clock is called the absolute time.
+ *
+ * The pipeline uses the clock to calculate the running time. Usually all
+ * renderers synchronize to the global clock using the buffer timestamps, the
+ * newsegment events and the element's base time, see #GstPipeline.
+ *
+ * A clock implementation can support periodic and single shot clock
+ * notifications both synchronous and asynchronous.
+ *
+ * One first needs to create a #GstClockID for the periodic or single shot
+ * notification using gst_clock_new_single_shot_id() or
+ * gst_clock_new_periodic_id().
+ *
+ * To perform a blocking wait for the specific time of the #GstClockID use the
+ * gst_clock_id_wait(). To receive a callback when the specific time is reached
+ * in the clock use gst_clock_id_wait_async(). Both these calls can be
+ * interrupted with the gst_clock_id_unschedule() call. If the blocking wait is
+ * unscheduled a return value of #GST_CLOCK_UNSCHEDULED is returned.
+ *
+ * Periodic callbacks scheduled async will be repeatedly called automatically
+ * until it is unscheduled. To schedule a sync periodic callback,
+ * gst_clock_id_wait() should be called repeatedly.
+ *
+ * The async callbacks can happen from any thread, either provided by the core
+ * or from a streaming thread. The application should be prepared for this.
+ *
+ * A #GstClockID that has been unscheduled cannot be used again for any wait
+ * operation, a new #GstClockID should be created and the old unscheduled one
+ * should be destroyed with gst_clock_id_unref().
+ *
+ * It is possible to perform a blocking wait on the same #GstClockID from
+ * multiple threads. However, registering the same #GstClockID for multiple
+ * async notifications is not possible, the callback will only be called for
+ * the thread registering the entry last.
+ *
+ * None of the wait operations unref the #GstClockID, the owner is responsible
+ * for unreffing the ids itself. This holds for both periodic and single shot
+ * notifications. The reason being that the owner of the #GstClockID has to
+ * keep a handle to the #GstClockID to unblock the wait on FLUSHING events or
+ * state changes and if the entry would be unreffed automatically, the handle
+ * might become invalid without any notification.
+ *
+ * These clock operations do not operate on the running time, so the callbacks
+ * will also occur when not in PLAYING state as if the clock just keeps on
+ * running. Some clocks however do not progress when the element that provided
+ * the clock is not PLAYING.
+ *
+ * When a clock has the #GST_CLOCK_FLAG_CAN_SET_MASTER flag set, it can be
+ * slaved to another #GstClock with the gst_clock_set_master(). The clock will
+ * then automatically be synchronized to this master clock by repeatedly
+ * sampling the master clock and the slave clock and recalibrating the slave
+ * clock with gst_clock_set_calibration(). This feature is mostly useful for
+ * plugins that have an internal clock but must operate with another clock
+ * selected by the #GstPipeline.  They can track the offset and rate difference
+ * of their internal clock relative to the master clock by using the
+ * gst_clock_get_calibration() function.
+ *
+ * The master/slave synchronisation can be tuned with the #GstClock:timeout,
+ * #GstClock:window-size and #GstClock:window-threshold properties.
+ * The #GstClock:timeout property defines the interval to sample the master
+ * clock and run the calibration functions. #GstClock:window-size defines the
+ * number of samples to use when calibrating and #GstClock:window-threshold
+ * defines the minimum number of samples before the calibration is performed.

+ * @short_description: Build configuration options
+ *
+ * This describes the configuration options for GStreamer. When building
+ * GStreamer there are a lot of parts (known internally as "subsystems" ) that
+ * can be disabled for various reasons. The most common reasons are speed and
+ * size, which is important because GStreamer is designed to run on embedded
+ * systems.
+ *
+ * If a subsystem is disabled, most of this changes are done in an API
+ * compatible way, so you don't need to adapt your code in most cases. It is
+ * never done in an ABI compatible way though. So if you want to disable a
+ * subsystem, you have to rebuild all programs depending on GStreamer, too.
+ *
+ * If a subsystem is disabled in GStreamer, a value is defined in
+ * <gst/gst.h>. You can check this if you do subsystem-specific stuff.

+ * @short_description: Lightweight objects to represent element contexts
+ * @see_also: #GstMiniObject, #GstElement
+ *
+ * #GstContext is a container object used to store contexts like a device
+ * context, a display server connection and similar concepts that should
+ * be shared between multiple elements.
+ *
+ * Applications can set a context on a complete pipeline by using
+ * gst_element_set_context(), which will then be propagated to all
+ * child elements. Elements can handle these in #GstElementClass.set_context()
+ * and merge them with the context information they already have.
+ *
+ * When an element needs a context it will do the following actions in this
+ * order until one step succeeds:
+ * 1. Check if the element already has a context
+ * 2. Query downstream with GST_QUERY_CONTEXT for the context
+ * 3. Query upstream with GST_QUERY_CONTEXT for the context
+ * 4. Post a GST_MESSAGE_NEED_CONTEXT message on the bus with the required
+ *    context types and afterwards check if a usable context was set now
+ * 5. Create a context by itself and post a GST_MESSAGE_HAVE_CONTEXT message
+ *    on the bus.
+ *
+ * Bins will catch GST_MESSAGE_NEED_CONTEXT messages and will set any previously
+ * known context on the element that asks for it if possible. Otherwise the
+ * application should provide one if it can.
+ *
+ * #GstContexts can be persistent.
+ * A persistent #GstContext is kept in elements when they reach
+ * %GST_STATE_NULL, non-persistent ones will be removed.
+ * Also, a non-persistent context won't override a previous persistent
+ * context set to an element.

+ * @short_description: attachment for control source sources
+ *
+ * A base class for value mapping objects that attaches control sources to gobject
+ * properties. Such an object is taking one or more #GstControlSource instances,
+ * combines them and maps the resulting value to the type and value range of the
+ * bound property.

+ * - we create the control_binding for a certain object anyway
+ * - we could call gst_object_add_control_binding() at the end of
+ *   gst_control_binding_constructor()
+ * - the weak-ref on object is not nice, as is the same as gst_object_parent()
+ *   once the object is added to the parent
+ *
+ * - another option would be to defer what is done in _constructor to when
+ *   the parent is set (need to listen to the signal then)
+ *   then basically I could
+ *   a) remove the obj arg and wait the binding to be added or
+ *   b) add the binding from constructor, unref object there and make obj
+ *      writeonly

+ * @short_description: base class for control source sources
+ *
+ * The #GstControlSource is a base class for control value sources that could
+ * be used to get timestamp-value pairs. A control source essentially is a
+ * function over time.
+ *
+ * A #GstControlSource is used by first getting an instance of a specific
+ * control-source, creating a binding for the control-source to the target property
+ * of the element and then adding the binding to the element. The binding will
+ * convert the data types and value range to fit to the bound property.
+ *
+ * For implementing a new #GstControlSource one has to implement
+ * #GstControlSourceGetValue and #GstControlSourceGetValueArray functions.
+ * These are then used by gst_control_source_get_value() and
+ * gst_control_source_get_value_array() to get values for specific timestamps.

+ * SECTION:gstelement
+ * @title: GstElement
+ * @short_description: Abstract base class for all pipeline elements
+ * @see_also: #GstElementFactory, #GstPad
+ *
+ * GstElement is the abstract base class needed to construct an element that
+ * can be used in a GStreamer pipeline. Please refer to the plugin writers
+ * guide for more information on creating #GstElement subclasses.
+ *
+ * The name of a #GstElement can be get with gst_element_get_name() and set with
+ * gst_element_set_name().  For speed, GST_ELEMENT_NAME() can be used in the
+ * core when using the appropriate locking. Do not use this in plug-ins or
+ * applications in order to retain ABI compatibility.
+ *
+ * Elements can have pads (of the type #GstPad).  These pads link to pads on
+ * other elements.  #GstBuffer flow between these linked pads.
+ * A #GstElement has a #GList of #GstPad structures for all their input (or sink)
+ * and output (or source) pads.
+ * Core and plug-in writers can add and remove pads with gst_element_add_pad()
+ * and gst_element_remove_pad().
+ *
+ * An existing pad of an element can be retrieved by name with
+ * gst_element_get_static_pad(). A new dynamic pad can be created using
+ * gst_element_request_pad() with a #GstPadTemplate.
+ * An iterator of all pads can be retrieved with gst_element_iterate_pads().
+ *
+ * Elements can be linked through their pads.
+ * If the link is straightforward, use the gst_element_link()
+ * convenience function to link two elements, or gst_element_link_many()
+ * for more elements in a row.
+ * Use gst_element_link_filtered() to link two elements constrained by
+ * a specified set of #GstCaps.
+ * For finer control, use gst_element_link_pads() and
+ * gst_element_link_pads_filtered() to specify the pads to link on
+ * each element by name.
+ *
+ * Each element has a state (see #GstState).  You can get and set the state
+ * of an element with gst_element_get_state() and gst_element_set_state().
+ * Setting a state triggers a #GstStateChange. To get a string representation
+ * of a #GstState, use gst_element_state_get_name().
+ *
+ * You can get and set a #GstClock on an element using gst_element_get_clock()
+ * and gst_element_set_clock().
+ * Some elements can provide a clock for the pipeline if
+ * the #GST_ELEMENT_FLAG_PROVIDE_CLOCK flag is set. With the
+ * gst_element_provide_clock() method one can retrieve the clock provided by
+ * such an element.
+ * Not all elements require a clock to operate correctly. If the
+ * #GST_ELEMENT_FLAG_REQUIRE_CLOCK() flag is set, a clock should be set on the
+ * element with gst_element_set_clock().
+ *
+ * Note that clock selection and distribution is normally handled by the
+ * toplevel #GstPipeline so the clock functions are only to be used in very
+ * specific situations.

+ * GstElement:
+ * @state_lock: Used to serialize execution of gst_element_set_state()
+ * @state_cond: Used to signal completion of a state change
+ * @state_cookie: Used to detect concurrent execution of
+ * gst_element_set_state() and gst_element_get_state()
+ * @target_state: the target state of an element as set by the application
+ * @current_state: the current state of an element
+ * @next_state: the next state of an element, can be #GST_STATE_VOID_PENDING if
+ * the element is in the correct state.
+ * @pending_state: the final state the element should go to, can be
+ * #GST_STATE_VOID_PENDING if the element is in the correct state
+ * @last_return: the last return value of an element state change
+ * @bus: the bus of the element. This bus is provided to the element by the
+ * parent element or the application. A #GstPipeline has a bus of its own.
+ * @clock: the clock of the element. This clock is usually provided to the
+ * element by the toplevel #GstPipeline.
+ * @base_time: the time of the clock right before the element is set to
+ * PLAYING. Subtracting @base_time from the current clock time in the PLAYING
+ * state will yield the running_time against the clock.
+ * @start_time: the running_time of the last PAUSED state
+ * @numpads: number of pads of the element, includes both source and sink pads.
+ * @pads: (element-type Gst.Pad): list of pads
+ * @numsrcpads: number of source pads of the element.
+ * @srcpads: (element-type Gst.Pad): list of source pads
+ * @numsinkpads: number of sink pads of the element.
+ * @sinkpads: (element-type Gst.Pad): list of sink pads
+ * @pads_cookie: updated whenever the a pad is added or removed
+ * @contexts: (element-type Gst.Context): list of contexts

+ * #GstElementFactory is used to create instances of elements. A

+ * Use the gst_element_factory_find() and gst_element_factory_create()

+ * convenient shortcut.
+ *
+ * The following code example shows you how to create a GstFileSrc element.

+/**
+ * SECTION:gsterror
+ * @title: GstError
+ * @short_description: Categorized error messages
+ * @see_also: #GstMessage
+ *
+ * GStreamer elements can throw non-fatal warnings and fatal errors.
+ * Higher-level elements and applications can programmatically filter
+ * the ones they are interested in or can recover from,
+ * and have a default handler handle the rest of them.
+ *
+ * The rest of this section will use the term error
+ * to mean both (non-fatal) warnings and (fatal) errors; they are treated
+ * similarly.
+ *
+ * Errors from elements are the combination of a #GError and a debug string.
+ * The #GError contains:
+ * - a domain type: CORE, LIBRARY, RESOURCE or STREAM
+ * - a code: an enum value specific to the domain
+ * - a translated, human-readable message
+ * - a non-translated additional debug string, which also contains
+ * - file and line information
+ *
+ * Elements do not have the context required to decide what to do with
+ * errors.  As such, they should only inform about errors, and stop their
+ * processing.  In short, an element doesn't know what it is being used for.
+ *
+ * It is the application or compound element using the given element that
+ * has more context about the use of the element. Errors can be received by
+ * listening to the #GstBus of the element/pipeline for #GstMessage objects with
+ * the type %GST_MESSAGE_ERROR or %GST_MESSAGE_WARNING. The thrown errors should
+ * be inspected, and filtered if appropriate.
+ *
+ * An application is expected to, by default, present the user with a
+ * dialog box (or an equivalent) showing the error message.  The dialog
+ * should also allow a way to get at the additional debug information,
+ * so the user can provide bug reporting information.
+ *
+ * A compound element is expected to forward errors by default higher up
+ * the hierarchy; this is done by default in the same way as for other types
+ * of #GstMessage.
+ *
+ * When applications or compound elements trigger errors that they can
+ * recover from, they can filter out these errors and take appropriate action.
+ * For example, an application that gets an error from xvimagesink
+ * that indicates all XVideo ports are taken, the application can attempt
+ * to use another sink instead.
+ *
+ * Elements throw errors using the #GST_ELEMENT_ERROR convenience macro:
+ *
+ * ## Throwing an error
+ *
+ *   |[
+ *     GST_ELEMENT_ERROR (src, RESOURCE, NOT_FOUND,
+ *       (_("No file name specified for reading.")), (NULL));
+ *   ]|
+ *
+ * Things to keep in mind:
+ *
+ *   * Don't go off inventing new error codes.  The ones
+ *     currently provided should be enough.  If you find your type of error
+ *     does not fit the current codes, you should use FAILED.
+ *   * Don't provide a message if the default one suffices.
+ *     this keeps messages more uniform.  Use (%NULL) - not forgetting the
+ *     parentheses.
+ *   * If you do supply a custom message, it should be
+ *     marked for translation.  The message should start with a capital
+ *     and end with a period.  The message should describe the error in short,
+ *     in a human-readable form, and without any complex technical terms.
+ *     A user interface will present this message as the first thing a user
+ *     sees.  Details, technical info, ... should go in the debug string.
+ *
+ *   * The debug string can be as you like.  Again, use (%NULL)
+ *     if there's nothing to add - file and line number will still be
+ *     passed.  #GST_ERROR_SYSTEM can be used as a shortcut to give
+ *     debug information on a system call error.
+ *
+ */
+
+/* FIXME 2.0: the entire error system needs an overhaul - it's not very
+ * useful the way it is. Also, we need to be able to specify additional
+ * 'details' for errors (e.g. disk/file/resource error -> out-of-space; or
+ * put the url/filename/device name that caused the error somewhere)
+ * without having to add enums for every little thing.
+ *
+ * FIXME 2.0: get rid of GST_{CORE,LIBRARY,RESOURCE,STREAM}_ERROR_NUM_ERRORS.
+ * Maybe also replace _quark() functions with g_quark_from_static_string()?

+ * @short_description: Structure describing events that are passed up and down
+ *                     a pipeline
+ * @see_also: #GstPad, #GstElement
+ *
+ * The event class provides factory methods to construct events for sending
+ * and functions to query (parse) received events.
+ *
+ * Events are usually created with gst_event_new_*() which takes event-type
+ * specific parameters as arguments.
+ * To send an event application will usually use gst_element_send_event() and
+ * elements will use gst_pad_send_event() or gst_pad_push_event().
+ * The event should be unreffed with gst_event_unref() if it has not been sent.
+ *
+ * Events that have been received can be parsed with their respective
+ * gst_event_parse_*() functions. It is valid to pass %NULL for unwanted details.
+ *
+ * Events are passed between elements in parallel to the data stream. Some events
+ * are serialized with buffers, others are not. Some events only travel downstream,
+ * others only upstream. Some events can travel both upstream and downstream.
+ *
+ * The events are used to signal special conditions in the datastream such as
+ * EOS (end of stream) or the start of a new stream-segment.
+ * Events are also used to flush the pipeline of any pending data.
+ *
+ * Most of the event API is used inside plugins. Applications usually only
+ * construct and use seek events.
+ * To do that gst_event_new_seek() is used to create a seek event. It takes
+ * the needed parameters to specify seeking time and mode.
+ * |[
+ *   GstEvent *event;
+ *   gboolean result;
+ *   ...
+ *   // construct a seek event to play the media from second 2 to 5, flush
+ *   // the pipeline to decrease latency.
+ *   event = gst_event_new_seek (1.0,
+ *      GST_FORMAT_TIME,
+ *      GST_SEEK_FLAG_FLUSH,
+ *      GST_SEEK_TYPE_SET, 2 * GST_SECOND,
+ *      GST_SEEK_TYPE_SET, 5 * GST_SECOND);
+ *   ...

+ * @proportion: the proportion of the qos message
+ * @diff: The time difference of the last Clock sync
+ * @timestamp: The timestamp of the buffer
+ *
+ * Allocate a new qos event with the given values.
+ * The QOS event is generated in an element that wants an upstream
+ * element to either reduce or increase its rate because of
+ * high/low CPU load or other resource usage such as network performance or
+ * throttling. Typically sinks generate these events for each buffer
+ * they receive.
+ *
+ * @type indicates the reason for the QoS event. #GST_QOS_TYPE_OVERFLOW is
+ * used when a buffer arrived in time or when the sink cannot keep up with
+ * the upstream datarate. #GST_QOS_TYPE_UNDERFLOW is when the sink is not
+ * receiving buffers fast enough and thus has to drop late buffers.
+ * #GST_QOS_TYPE_THROTTLE is used when the datarate is artificially limited
+ * by the application, for example to reduce power consumption.
+ *
+ * @proportion indicates the real-time performance of the streaming in the
+ * element that generated the QoS event (usually the sink). The value is
+ * generally computed based on more long term statistics about the streams
+ * timestamps compared to the clock.
+ * A value < 1.0 indicates that the upstream element is producing data faster
+ * than real-time. A value > 1.0 indicates that the upstream element is not
+ * producing data fast enough. 1.0 is the ideal @proportion value. The
+ * proportion value can safely be used to lower or increase the quality of
+ * the element.
+ *
+ * @diff is the difference against the clock in running time of the last
+ * buffer that caused the element to generate the QOS event. A negative value
+ * means that the buffer with @timestamp arrived in time. A positive value
+ * indicates how late the buffer with @timestamp was. When throttling is
+ * enabled, @diff will be set to the requested throttling interval.
+ *
+ * @timestamp is the timestamp of the last buffer that cause the element
+ * to generate the QOS event. It is expressed in running time and thus an ever
+ * increasing value.
+ *
+ * The upstream element can use the @diff and @timestamp values to decide
+ * whether to process more buffers. For positive @diff, all buffers with
+ * timestamp <= @timestamp + @diff will certainly arrive late in the sink
+ * as well. A (negative) @diff value so that @timestamp + @diff would yield a
+ * result smaller than 0 is not allowed.
+ *
+ * The application can use general event probes to intercept the QoS
+ * event and implement custom application specific QoS handling.

+ *
+ * GhostPads are useful when organizing pipelines with #GstBin like elements.
+ * The idea here is to create hierarchical element graphs. The bin element
+ * contains a sub-graph. Now one would like to treat the bin-element like any
+ * other #GstElement. This is where GhostPads come into play. A GhostPad acts as
+ * a proxy for another pad. Thus the bin can have sink and source ghost-pads
+ * that are associated with sink and source pads of the child elements.
+ *
+ * If the target pad is known at creation time, gst_ghost_pad_new() is the
+ * function to use to get a ghost-pad. Otherwise one can use gst_ghost_pad_new_no_target()
+ * to create the ghost-pad and use gst_ghost_pad_set_target() to establish the
+ * association later on.
+ *
+ * Note that GhostPads add overhead to the data processing of a pipeline.

+/**
+ * SECTION:gstinfo
+ * @title: GstInfo
+ * @short_description: Debugging and logging facilities
+ * @see_also: #gst-running for command line parameters
+ * and environment variables that affect the debugging output.
+ *
+ * GStreamer's debugging subsystem is an easy way to get information about what
+ * the application is doing.  It is not meant for programming errors. Use GLib
+ * methods (g_warning and friends) for that.
+ *
+ * The debugging subsystem works only after GStreamer has been initialized
+ * - for example by calling gst_init().
+ *
+ * The debugging subsystem is used to log informational messages while the
+ * application runs.  Each messages has some properties attached to it. Among
+ * these properties are the debugging category, the severity (called "level"
+ * here) and an optional #GObject it belongs to. Each of these messages is sent
+ * to all registered debugging handlers, which then handle the messages.
+ * GStreamer attaches a default handler on startup, which outputs requested
+ * messages to stderr.
+ *
+ * Messages are output by using shortcut macros like #GST_DEBUG,
+ * #GST_CAT_ERROR_OBJECT or similar. These all expand to calling gst_debug_log()
+ * with the right parameters.
+ * The only thing a developer will probably want to do is define his own
+ * categories. This is easily done with 3 lines. At the top of your code,
+ * declare
+ * the variables and set the default category.
+ * |[
+ *   GST_DEBUG_CATEGORY_STATIC (my_category);  // define category (statically)
+ *   #define GST_CAT_DEFAULT my_category       // set as default
+ * ]|
+ * After that you only need to initialize the category.
+ * |[
+ *   GST_DEBUG_CATEGORY_INIT (my_category, "my category",
+ *                            0, "This is my very own");
+ * ]|
+ * Initialization must be done before the category is used first.
+ * Plugins do this
+ * in their plugin_init function, libraries and applications should do that
+ * during their initialization.
+ *
+ * The whole debugging subsystem can be disabled at build time with passing the
+ * --disable-gst-debug switch to configure. If this is done, every function,
+ * macro and even structs described in this file evaluate to default values or
+ * nothing at all.
+ * So don't take addresses of these functions or use other tricks.
+ * If you must do that for some reason, there is still an option.
+ * If the debugging
+ * subsystem was compiled out, #GST_DISABLE_GST_DEBUG is defined in
+ * <gst/gst.h>,
+ * so you can check that before doing your trick.
+ * Disabling the debugging subsystem will give you a slight (read: unnoticeable)
+ * speed increase and will reduce the size of your compiled code. The GStreamer
+ * library itself becomes around 10% smaller.
+ *
+ * Please note that there are naming conventions for the names of debugging
+ * categories. These are explained at GST_DEBUG_CATEGORY_INIT().

+ * GstDebugLevel:
+ * @GST_LEVEL_NONE: No debugging level specified or desired. Used to deactivate
+ *  debugging output.
+ * @GST_LEVEL_ERROR: Error messages are to be used only when an error occurred
+ *  that stops the application from keeping working correctly.
+ *  An examples is gst_element_error, which outputs a message with this priority.
+ *  It does not mean that the application is terminating as with g_error.
+ * @GST_LEVEL_WARNING: Warning messages are to inform about abnormal behaviour
+ *  that could lead to problems or weird behaviour later on. An example of this
+ *  would be clocking issues ("your computer is pretty slow") or broken input
+ *  data ("Can't synchronize to stream.")
+ * @GST_LEVEL_FIXME: Fixme messages are messages that indicate that something
+ *  in the executed code path is not fully implemented or handled yet. Note
+ *  that this does not replace proper error handling in any way, the purpose
+ *  of this message is to make it easier to spot incomplete/unfinished pieces
+ *  of code when reading the debug log.
+ * @GST_LEVEL_INFO: Informational messages should be used to keep the developer
+ *  updated about what is happening.
+ *  Examples where this should be used are when a typefind function has
+ *  successfully determined the type of the stream or when an mp3 plugin detects
+ *  the format to be used. ("This file has mono sound.")
+ * @GST_LEVEL_DEBUG: Debugging messages should be used when something common
+ *  happens that is not the expected default behavior, or something that's
+ *  useful to know but doesn't happen all the time (ie. per loop iteration or
+ *  buffer processed or event handled).
+ *  An example would be notifications about state changes or receiving/sending
+ *  of events.
+ * @GST_LEVEL_LOG: Log messages are messages that are very common but might be
+ *  useful to know. As a rule of thumb a pipeline that is running as expected
+ *  should never output anything else but LOG messages whilst processing data.
+ *  Use this log level to log recurring information in chain functions and
+ *  loop functions, for example.
+ * @GST_LEVEL_TRACE: Tracing-related messages.
+ *  Examples for this are referencing/dereferencing of objects.
+ * @GST_LEVEL_MEMDUMP: memory dump messages are used to log (small) chunks of
+ *  data as memory dumps in the log. They will be displayed as hexdump with
+ *  ASCII characters.
+ * @GST_LEVEL_COUNT: The number of defined debugging levels.
+ *
+ * The level defines the importance of a debugging message. The more important a
+ * message is, the greater the probability that the debugging system outputs it.

+ * SECTION:gstiterator
+ * @title: GstIterator
+ * @short_description: Object to retrieve multiple elements in a threadsafe
+ * way.
+ * @see_also: #GstElement, #GstBin
+ *
+ * A GstIterator is used to retrieve multiple objects from another object in
+ * a threadsafe way.
+ *
+ * Various GStreamer objects provide access to their internal structures using
+ * an iterator.
+ *
+ * Note that if calling a GstIterator function results in your code receiving
+ * a refcounted object (with, say, g_value_get_object()), the refcount for that
+ * object will not be increased. Your code is responsible for taking a reference
+ * if it wants to continue using it later.
+ *
+ * The basic use pattern of an iterator is as follows:
+ * |[
+ *   GstIterator *it = _get_iterator(object);
+ *   GValue item = G_VALUE_INIT;
+ *   done = FALSE;
+ *   while (!done) {
+ *     switch (gst_iterator_next (it, &item)) {
+ *       case GST_ITERATOR_OK:
+ *         ...get/use/change item here...
+ *         g_value_reset (&item);
+ *         break;
+ *       case GST_ITERATOR_RESYNC:
+ *         ...rollback changes to items...
+ *         gst_iterator_resync (it);
+ *         break;
+ *       case GST_ITERATOR_ERROR:
+ *         ...wrong parameters were given...
+ *         done = TRUE;
+ *         break;
+ *       case GST_ITERATOR_DONE:
+ *         done = TRUE;
+ *         break;
+ *     }
+ *   }
+ *   g_value_unset (&item);

+ * SECTION:gstmemory
+ * @title: GstMemory
+ * @short_description: refcounted wrapper for memory blocks
+ * @see_also: #GstBuffer
+ *
+ * GstMemory is a lightweight refcounted object that wraps a region of memory.
+ * They are typically used to manage the data of a #GstBuffer.
+ *
+ * A GstMemory object has an allocated region of memory of maxsize. The maximum
+ * size does not change during the lifetime of the memory object. The memory
+ * also has an offset and size property that specifies the valid range of memory
+ * in the allocated region.
+ *
+ * Memory is usually created by allocators with a gst_allocator_alloc()
+ * method call. When %NULL is used as the allocator, the default allocator will
+ * be used.
+ *
+ * New allocators can be registered with gst_allocator_register().
+ * Allocators are identified by name and can be retrieved with
+ * gst_allocator_find(). gst_allocator_set_default() can be used to change the
+ * default allocator.
+ *
+ * New memory can be created with gst_memory_new_wrapped() that wraps the memory
+ * allocated elsewhere.
+ *
+ * Refcounting of the memory block is performed with gst_memory_ref() and
+ * gst_memory_unref().
+ *
+ * The size of the memory can be retrieved and changed with
+ * gst_memory_get_sizes() and gst_memory_resize() respectively.
+ *
+ * Getting access to the data of the memory is performed with gst_memory_map().
+ * The call will return a pointer to offset bytes into the region of memory.
+ * After the memory access is completed, gst_memory_unmap() should be called.
+ *
+ * Memory can be copied with gst_memory_copy(), which will return a writable
+ * copy. gst_memory_share() will create a new memory block that shares the
+ * memory with an existing memory block at a custom offset and with a custom
+ * size.
+ *
+ * Memory can be efficiently merged when gst_memory_is_span() returns %TRUE.

+ * @see_also: #GstBus, #GstMiniObject, #GstElement
+ *
+ * Messages are implemented as a subclass of #GstMiniObject with a generic
+ * #GstStructure as the content. This allows for writing custom messages without
+ * requiring an API change while allowing a wide range of different types
+ * of messages.
+ *
+ * Messages are posted by objects in the pipeline and are passed to the
+ * application using the #GstBus.
+ *
+ * The basic use pattern of posting a message on a #GstBus is as follows:
+ * |[
+ *   gst_bus_post (bus, gst_message_new_eos());
+ * ]|
+ *
+ * A #GstElement usually posts messages on the bus provided by the parent
+ * container using gst_element_post_message().

+ * Creates a new redirect message and adds a new entry to it. Redirect messages
+ * are posted when an element detects that the actual data has to be retrieved
+ * from a different location. This is useful if such a redirection cannot be
+ * handled inside a source element, for example when HTTP 302/303 redirects
+ * return a non-HTTP URL.
+ *
+ * The redirect message can hold multiple entries. The first one is added
+ * when the redirect message is created, with the given location, tag_list,
+ * entry_struct arguments. Use gst_message_add_redirect_entry() to add more
+ * entries.
+ *
+ * Each entry has a location, a tag list, and a structure. All of these are
+ * optional. The tag list and structure are useful for additional metadata,
+ * such as bitrate statistics for the given location.
+ *
+ * By default, message recipients should treat entries in the order they are
+ * stored. The recipient should therefore try entry #0 first, and if this
+ * entry is not acceptable or working, try entry #1 etc. Senders must make
+ * sure that they add entries in this order. However, recipients are free to
+ * ignore the order and pick an entry that is "best" for them. One example
+ * would be a recipient that scans the entries for the one with the highest
+ * bitrate tag.

+ * GstMessageType:
+ * @GST_MESSAGE_UNKNOWN: an undefined message
+ * @GST_MESSAGE_EOS: end-of-stream reached in a pipeline. The application will
+ * only receive this message in the PLAYING state and every time it sets a
+ * pipeline to PLAYING that is in the EOS state. The application can perform a
+ * flushing seek in the pipeline, which will undo the EOS state again.
+ * @GST_MESSAGE_ERROR: an error occurred. When the application receives an error
+ * message it should stop playback of the pipeline and not assume that more
+ * data will be played.
+ * @GST_MESSAGE_WARNING: a warning occurred.
+ * @GST_MESSAGE_INFO: an info message occurred
+ * @GST_MESSAGE_TAG: a tag was found.
+ * @GST_MESSAGE_BUFFERING: the pipeline is buffering. When the application
+ * receives a buffering message in the PLAYING state for a non-live pipeline it
+ * must PAUSE the pipeline until the buffering completes, when the percentage
+ * field in the message is 100%. For live pipelines, no action must be
+ * performed and the buffering percentage can be used to inform the user about
+ * the progress.
+ * @GST_MESSAGE_STATE_CHANGED: a state change happened
+ * @GST_MESSAGE_STATE_DIRTY: an element changed state in a streaming thread.
+ * This message is deprecated.
+ * @GST_MESSAGE_STEP_DONE: a stepping operation finished.
+ * @GST_MESSAGE_CLOCK_PROVIDE: an element notifies its capability of providing
+ *                             a clock. This message is used internally and
+ *                             never forwarded to the application.
+ * @GST_MESSAGE_CLOCK_LOST: The current clock as selected by the pipeline became
+ *                          unusable. The pipeline will select a new clock on
+ *                          the next PLAYING state change. The application
+ *                          should set the pipeline to PAUSED and back to
+ *                          PLAYING when this message is received.
+ * @GST_MESSAGE_NEW_CLOCK: a new clock was selected in the pipeline.
+ * @GST_MESSAGE_STRUCTURE_CHANGE: the structure of the pipeline changed. This
+ * message is used internally and never forwarded to the application.
+ * @GST_MESSAGE_STREAM_STATUS: status about a stream, emitted when it starts,
+ *                             stops, errors, etc..
+ * @GST_MESSAGE_APPLICATION: message posted by the application, possibly
+ *                           via an application-specific element.
+ * @GST_MESSAGE_ELEMENT: element-specific message, see the specific element's
+ *                       documentation
+ * @GST_MESSAGE_SEGMENT_START: pipeline started playback of a segment. This
+ * message is used internally and never forwarded to the application.
+ * @GST_MESSAGE_SEGMENT_DONE: pipeline completed playback of a segment. This
+ * message is forwarded to the application after all elements that posted
+ * @GST_MESSAGE_SEGMENT_START posted a GST_MESSAGE_SEGMENT_DONE message.
+ * @GST_MESSAGE_DURATION_CHANGED: The duration of a pipeline changed. The
+ * application can get the new duration with a duration query.
+ * @GST_MESSAGE_ASYNC_START: Posted by elements when they start an ASYNC
+ * #GstStateChange. This message is not forwarded to the application but is used
+ * internally.
+ * @GST_MESSAGE_ASYNC_DONE: Posted by elements when they complete an ASYNC
+ * #GstStateChange. The application will only receive this message from the toplevel
+ * pipeline.
+ * @GST_MESSAGE_LATENCY: Posted by elements when their latency changes. The
+ * application should recalculate and distribute a new latency.
+ * @GST_MESSAGE_REQUEST_STATE: Posted by elements when they want the pipeline to
+ * change state. This message is a suggestion to the application which can
+ * decide to perform the state change on (part of) the pipeline.
+ * @GST_MESSAGE_STEP_START: A stepping operation was started.
+ * @GST_MESSAGE_QOS: A buffer was dropped or an element changed its processing
+ * strategy for Quality of Service reasons.
+ * @GST_MESSAGE_PROGRESS: A progress message.
+ * @GST_MESSAGE_TOC: A new table of contents (TOC) was found or previously found TOC
+ * was updated.
+ * @GST_MESSAGE_RESET_TIME: Message to request resetting the pipeline's
+ *     running time from the pipeline. This is an internal message which
+ *     applications will likely never receive.
+ * @GST_MESSAGE_STREAM_START: Message indicating start of a new stream. Useful
+ *     e.g. when using playbin in gapless playback mode, to get notified when
+ *     the next title actually starts playing (which will be some time after
+ *     the URI for the next title has been set).
+ * @GST_MESSAGE_NEED_CONTEXT: Message indicating that an element wants a specific context (Since 1.2)
+ * @GST_MESSAGE_HAVE_CONTEXT: Message indicating that an element created a context (Since 1.2)
+ * @GST_MESSAGE_EXTENDED: Message is an extended message type (see below).
+ *     These extended message IDs can't be used directly with mask-based API
+ *     like gst_bus_poll() or gst_bus_timed_pop_filtered(), but you can still
+ *     filter for GST_MESSAGE_EXTENDED and then check the result for the
+ *     specific type. (Since 1.4)
+ * @GST_MESSAGE_DEVICE_ADDED: Message indicating a #GstDevice was added to
+ *     a #GstDeviceProvider (Since 1.4)
+ * @GST_MESSAGE_DEVICE_REMOVED: Message indicating a #GstDevice was removed
+ *     from a #GstDeviceProvider (Since 1.4)
+ * @GST_MESSAGE_PROPERTY_NOTIFY: Message indicating a #GObject property has
+ *     changed (Since 1.10)
+ * @GST_MESSAGE_STREAM_COLLECTION: Message indicating a new #GstStreamCollection
+ *     is available (Since 1.10)
+ * @GST_MESSAGE_STREAMS_SELECTED: Message indicating the active selection of
+ *     #GstStreams has changed (Since 1.10)
+ * @GST_MESSAGE_REDIRECT: Message indicating to request the application to
+ *     try to play the given URL(s). Useful if for example a HTTP 302/303
+ *     response is received with a non-HTTP URL inside. (Since 1.10)
+ * @GST_MESSAGE_ANY: mask for all of the above messages.

+ *
+ * A metadata API is registered with gst_meta_api_type_register() which takes a

+ *
+ * Multiple implementations of a metadata API can be registered.
+ * To implement a metadata API, gst_meta_register() should be used. This
+ * function takes all parameters needed to create, free and transform metadata
+ * along with the size of the metadata. The function returns a #GstMetaInfo
+ * structure that contains the information for the implementation of the API.
+ *
+ * A specific implementation can be retrieved by name with gst_meta_get_info().

+/**
+ * SECTION:gstobject
+ * @title: GstObject
+ * @short_description: Base class for the GStreamer object hierarchy
+ *
+ * #GstObject provides a root for the object hierarchy tree filed in by the
+ * GStreamer library.  It is currently a thin wrapper on top of
+ * #GInitiallyUnowned. It is an abstract class that is not very usable on its own.
+ *
+ * #GstObject gives us basic refcounting, parenting functionality and locking.
+ * Most of the functions are just extended for special GStreamer needs and can be
+ * found under the same name in the base class of #GstObject which is #GObject
+ * (e.g. g_object_ref() becomes gst_object_ref()).
+ *
+ * Since #GstObject derives from #GInitiallyUnowned, it also inherits the
+ * floating reference. Be aware that functions such as gst_bin_add() and
+ * gst_element_add_pad() take ownership of the floating reference.
+ *
+ * In contrast to #GObject instances, #GstObject adds a name property. The functions
+ * gst_object_set_name() and gst_object_get_name() are used to set/get the name
+ * of the object.
+ *
+ * ## controlled properties
+ *
+ * Controlled properties offers a lightweight way to adjust gobject properties
+ * over stream-time. It works by using time-stamped value pairs that are queued
+ * for element-properties. At run-time the elements continuously pull value
+ * changes for the current stream-time.
+ *
+ * What needs to be changed in a #GstElement?
+ * Very little - it is just two steps to make a plugin controllable!
+ *
+ *   * mark gobject-properties paramspecs that make sense to be controlled,
+ *     by GST_PARAM_CONTROLLABLE.
+ *
+ *   * when processing data (get, chain, loop function) at the beginning call
+ *     gst_object_sync_values(element,timestamp).
+ *     This will make the controller update all GObject properties that are
+ *     under its control with the current values based on the timestamp.
+ *
+ * What needs to be done in applications? Again it's not a lot to change.
+ *
+ *   * create a #GstControlSource.
+ *     csource = gst_interpolation_control_source_new ();
+ *     g_object_set (csource, "mode", GST_INTERPOLATION_MODE_LINEAR, NULL);
+ *
+ *   * Attach the #GstControlSource on the controller to a property.
+ *     gst_object_add_control_binding (object, gst_direct_control_binding_new (object, "prop1", csource));
+ *
+ *   * Set the control values
+ *     gst_timed_value_control_source_set ((GstTimedValueControlSource *)csource,0 * GST_SECOND, value1);
+ *     gst_timed_value_control_source_set ((GstTimedValueControlSource *)csource,1 * GST_SECOND, value2);
+ *
+ *   * start your pipeline

+/**
+ * SECTION:gstpad
+ * @title: GstPad
+ * @short_description: Object contained by elements that allows links to
+ *                     other elements
+ * @see_also: #GstPadTemplate, #GstElement, #GstEvent, #GstQuery, #GstBuffer
+ *
+ * A #GstElement is linked to other elements via "pads", which are extremely
+ * light-weight generic link points.
+ *
+ * Pads have a #GstPadDirection, source pads produce data, sink pads consume
+ * data.
+ *
+ * Pads are typically created from a #GstPadTemplate with
+ * gst_pad_new_from_template() and are then added to a #GstElement. This usually
+ * happens when the element is created but it can also happen dynamically based
+ * on the data that the element is processing or based on the pads that the
+ * application requests.
+ *
+ * Pads without pad templates can be created with gst_pad_new(),
+ * which takes a direction and a name as an argument.  If the name is %NULL,
+ * then a guaranteed unique name will be assigned to it.
+ *
+ * A #GstElement creating a pad will typically use the various
+ * gst_pad_set_*_function() calls to register callbacks for events, queries or
+ * dataflow on the pads.
+ *
+ * gst_pad_get_parent() will retrieve the #GstElement that owns the pad.
+ *
+ * After two pads are retrieved from an element by gst_element_get_static_pad(),
+ * the pads can be linked with gst_pad_link(). (For quick links,
+ * you can also use gst_element_link(), which will make the obvious
+ * link for you if it's straightforward.). Pads can be unlinked again with
+ * gst_pad_unlink(). gst_pad_get_peer() can be used to check what the pad is
+ * linked to.
+ *
+ * Before dataflow is possible on the pads, they need to be activated with
+ * gst_pad_set_active().
+ *
+ * gst_pad_query() and gst_pad_peer_query() can be used to query various
+ * properties of the pad and the stream.
+ *
+ * To send a #GstEvent on a pad, use gst_pad_send_event() and
+ * gst_pad_push_event(). Some events will be sticky on the pad, meaning that
+ * after they pass on the pad they can be queried later with
+ * gst_pad_get_sticky_event() and gst_pad_sticky_events_foreach().
+ * gst_pad_get_current_caps() and gst_pad_has_current_caps() are convenience
+ * functions to query the current sticky CAPS event on a pad.
+ *
+ * GstElements will use gst_pad_push() and gst_pad_pull_range() to push out
+ * or pull in a buffer.
+ *
+ * The dataflow, events and queries that happen on a pad can be monitored with
+ * probes that can be installed with gst_pad_add_probe(). gst_pad_is_blocked()
+ * can be used to check if a block probe is installed on the pad.
+ * gst_pad_is_blocking() checks if the blocking probe is currently blocking the
+ * pad. gst_pad_remove_probe() is used to remove a previously installed probe
+ * and unblock blocking probes if any.
+ *
+ * Pad have an offset that can be retrieved with gst_pad_get_offset(). This
+ * offset will be applied to the running_time of all data passing over the pad.
+ * gst_pad_set_offset() can be used to change the offset.
+ *
+ * Convenience functions exist to start, pause and stop the task on a pad with
+ * gst_pad_start_task(), gst_pad_pause_task() and gst_pad_stop_task()
+ * respectively.

+ *
+ * Pulls a @buffer from the peer pad or fills up a provided buffer.
+ *
+ * This function will first trigger the pad block signal if it was

+ *
+ * When @pad is not linked #GST_FLOW_NOT_LINKED is returned else this
+ * function returns the result of gst_pad_get_range() on the peer pad.
+ * See gst_pad_get_range() for a list of return values and for the
+ * semantics of the arguments of this function.
+ *
+ * If @buffer points to a variable holding %NULL, a valid new #GstBuffer will be
+ * placed in @buffer when this function returns #GST_FLOW_OK. The new buffer
+ * must be freed with gst_buffer_unref() after usage. When this function
+ * returns any other result value, @buffer will still point to %NULL.
+ *
+ * When @buffer points to a variable that points to a valid #GstBuffer, the
+ * buffer will be filled with the result data when this function returns
+ * #GST_FLOW_OK. When this function returns any other result value,
+ * @buffer will be unchanged. If the provided buffer is larger than @size, only
+ * @size bytes will be filled in the result buffer and its size will be updated
+ * accordingly.
+ *
+ * Note that less than @size bytes can be returned in @buffer when, for example,
+ * an EOS condition is near or when @buffer is not large enough to hold @size
+ * bytes. The caller should check the result buffer size to get the result size.
+ *
+ * Returns: a #GstFlowReturn from the peer pad.

+ * Sends the event to the pad. This function can be used
+ * by applications to send events in the pipeline.
+ *
+ * If @pad is a source pad, @event should be an upstream event. If @pad is a
+ * sink pad, @event should be a downstream event. For example, you would not
+ * send a #GST_EVENT_EOS on a src pad; EOS events only propagate downstream.
+ * Furthermore, some downstream events have to be serialized with data flow,
+ * like EOS, while some can travel out-of-band, like #GST_EVENT_FLUSH_START. If
+ * the event needs to be serialized with data flow, this function will take the
+ * pad's stream lock while calling its event function.
+ *
+ * To find out whether an event type is upstream, downstream, or downstream and
+ * serialized, see #GstEventTypeFlags, gst_event_type_get_flags(),
+ * #GST_EVENT_IS_UPSTREAM, #GST_EVENT_IS_DOWNSTREAM, and
+ * #GST_EVENT_IS_SERIALIZED. Note that in practice that an application or
+ * plugin doesn't need to bother itself with this information; the core handles
+ * all necessary locks and checks.
+ *
+ * This function takes ownership of the provided event so you should
+ * gst_event_ref() it if you want to reuse the event after this call.

+/**
+ * SECTION:gstpadtemplate
+ * @title: GstPadTemplate
+ * @short_description: Describe the media type of a pad.
+ * @see_also: #GstPad, #GstElementFactory
+ *
+ * Padtemplates describe the possible media types a pad or an elementfactory can
+ * handle. This allows for both inspection of handled types before loading the
+ * element plugin as well as identifying pads on elements that are not yet
+ * created (request or sometimes pads).
+ *
+ * Pad and PadTemplates have #GstCaps attached to it to describe the media type
+ * they are capable of dealing with. gst_pad_template_get_caps() or
+ * GST_PAD_TEMPLATE_CAPS() are used to get the caps of a padtemplate. It's not
+ * possible to modify the caps of a padtemplate after creation.
+ *
+ * PadTemplates have a #GstPadPresence property which identifies the lifetime
+ * of the pad and that can be retrieved with GST_PAD_TEMPLATE_PRESENCE(). Also
+ * the direction of the pad can be retrieved from the #GstPadTemplate with
+ * GST_PAD_TEMPLATE_DIRECTION().
+ *
+ * The GST_PAD_TEMPLATE_NAME_TEMPLATE () is important for GST_PAD_REQUEST pads
+ * because it has to be used as the name in the gst_element_get_request_pad()
+ * call to instantiate a pad from this template.
+ *
+ * Padtemplates can be created with gst_pad_template_new() or with
+ * gst_static_pad_template_get (), which creates a #GstPadTemplate from a
+ * #GstStaticPadTemplate that can be filled with the
+ * convenient GST_STATIC_PAD_TEMPLATE() macro.
+ *
+ * A padtemplate can be used to create a pad (see gst_pad_new_from_template()
+ * or gst_pad_new_from_static_template ()) or to add to an element class
+ * (see gst_element_class_add_static_pad_template ()).
+ *
+ * The following code example shows the code to create a pad from a padtemplate.
+ * |[
+ *   GstStaticPadTemplate my_template =
+ *   GST_STATIC_PAD_TEMPLATE (
+ *     "sink",          // the name of the pad
+ *     GST_PAD_SINK,    // the direction of the pad
+ *     GST_PAD_ALWAYS,  // when this pad will be present
+ *     GST_STATIC_CAPS (        // the capabilities of the padtemplate
+ *       "audio/x-raw, "
+ *         "channels = (int) [ 1, 6 ]"
+ *     )
+ *   );
+ *   void
+ *   my_method (void)
+ *   {
+ *     GstPad *pad;
+ *     pad = gst_pad_new_from_static_template (&my_template, "sink");
+ *     ...
+ *   }
+ * ]|
+ *
+ * The following example shows you how to add the padtemplate to an
+ * element class, this is usually done in the class_init of the class:
+ * |[
+ *   static void
+ *   my_element_class_init (GstMyElementClass *klass)
+ *   {
+ *     GstElementClass *gstelement_class = GST_ELEMENT_CLASS (klass);
+ *
+ *     gst_element_class_add_static_pad_template (gstelement_class, &my_template);
+ *   }
+ * ]|

+/**
+ * SECTION:gstpipeline
+ * @title: GstPipeline
+ * @short_description: Top-level bin with clocking and bus management
+                       functionality.
+ * @see_also: #GstElement, #GstBin, #GstClock, #GstBus
+ *
+ * A #GstPipeline is a special #GstBin used as the toplevel container for
+ * the filter graph. The #GstPipeline will manage the selection and
+ * distribution of a global #GstClock as well as provide a #GstBus to the
+ * application.
+ *
+ * gst_pipeline_new() is used to create a pipeline. when you are done with
+ * the pipeline, use gst_object_unref() to free its resources including all
+ * added #GstElement objects (if not otherwise referenced).
+ *
+ * Elements are added and removed from the pipeline using the #GstBin
+ * methods like gst_bin_add() and gst_bin_remove() (see #GstBin).
+ *
+ * Before changing the state of the #GstPipeline (see #GstElement) a #GstBus
+ * can be retrieved with gst_pipeline_get_bus(). This bus can then be
+ * used to receive #GstMessage from the elements in the pipeline.
+ *
+ * By default, a #GstPipeline will automatically flush the pending #GstBus
+ * messages when going to the NULL state to ensure that no circular
+ * references exist when no messages are read from the #GstBus. This
+ * behaviour can be changed with gst_pipeline_set_auto_flush_bus().
+ *
+ * When the #GstPipeline performs the PAUSED to PLAYING state change it will
+ * select a clock for the elements. The clock selection algorithm will by
+ * default select a clock provided by an element that is most upstream
+ * (closest to the source). For live pipelines (ones that return
+ * #GST_STATE_CHANGE_NO_PREROLL from the gst_element_set_state() call) this
+ * will select the clock provided by the live source. For normal pipelines
+ * this will select a clock provided by the sinks (most likely the audio
+ * sink). If no element provides a clock, a default #GstSystemClock is used.
+ *
+ * The clock selection can be controlled with the gst_pipeline_use_clock()
+ * method, which will enforce a given clock on the pipeline. With
+ * gst_pipeline_auto_clock() the default clock selection algorithm can be
+ * restored.
+ *
+ * A #GstPipeline maintains a running time for the elements. The running
+ * time is defined as the difference between the current clock time and
+ * the base time. When the pipeline goes to READY or a flushing seek is
+ * performed on it, the running time is reset to 0. When the pipeline is
+ * set from PLAYING to PAUSED, the current clock time is sampled and used to
+ * configure the base time for the elements when the pipeline is set
+ * to PLAYING again. The effect is that the running time (as the difference
+ * between the clock time and the base time) will count how much time was spent
+ * in the PLAYING state. This default behaviour can be changed with the
+ * gst_element_set_start_time() method.

+ *
+ * GStreamer is extensible, so #GstElement instances can be loaded at runtime.
+ * A plugin system can provide one or more of the basic
+ * GStreamer #GstPluginFeature subclasses.
+ *
+ * A plugin should export a symbol gst_plugin_desc that is a
+ * struct of type #GstPluginDesc.
+ * the plugin loader will check the version of the core library the plugin was
+ * linked against and will create a new #GstPlugin. It will then call the
+ * #GstPluginInitFunc function that was provided in the
+ * gst_plugin_desc.
+ *
+ * Once you have a handle to a #GstPlugin (e.g. from the #GstRegistry), you
+ * can add any object that subclasses #GstPluginFeature.
+ *
+ * Usually plugins are always automatically loaded so you don't need to call
+ * gst_plugin_load() explicitly to bring it into memory. There are options to
+ * statically link plugins to an app or even use GStreamer without a plugin
+ * repository in which case gst_plugin_load() can be needed to bring the plugin

+ * SECTION:gstpoll
+ * @title: GstPoll
+ * @short_description: Keep track of file descriptors and make it possible
+ *                     to wait on them in a cancellable way
+ *
+ * A #GstPoll keeps track of file descriptors much like fd_set (used with
+ * select()) or a struct pollfd array (used with poll()). Once created with
+ * gst_poll_new(), the set can be used to wait for file descriptors to be
+ * readable and/or writable. It is possible to make this wait be controlled
+ * by specifying %TRUE for the @controllable flag when creating the set (or
+ * later calling gst_poll_set_controllable()).
+ *
+ * New file descriptors are added to the set using gst_poll_add_fd(), and
+ * removed using gst_poll_remove_fd(). Controlling which file descriptors
+ * should be waited for to become readable and/or writable are done using
+ * gst_poll_fd_ctl_read() and gst_poll_fd_ctl_write().
+ *
+ * Use gst_poll_wait() to wait for the file descriptors to actually become
+ * readable and/or writable, or to timeout if no file descriptor is available
+ * in time. The wait can be controlled by calling gst_poll_restart() and
+ * gst_poll_set_flushing().
+ *
+ * Once the file descriptor set has been waited for, one can use
+ * gst_poll_fd_has_closed() to see if the file descriptor has been closed,
+ * gst_poll_fd_has_error() to see if it has generated an error,
+ * gst_poll_fd_can_read() to see if it is possible to read from the file
+ * descriptor, and gst_poll_fd_can_write() to see if it is possible to
+ * write to it.

+/**
+ * SECTION:gstpreset
+ * @title: GstPreset
+ * @short_description: helper interface for element presets
+ *
+ * This interface offers methods to query and manipulate parameter preset sets.
+ * A preset is a bunch of property settings, together with meta data and a name.
+ * The name of a preset serves as key for subsequent method calls to manipulate
+ * single presets.
+ * All instances of one type will share the list of presets. The list is created
+ * on demand, if presets are not used, the list is not created.
+ *
+ * The interface comes with a default implementation that serves most plugins.
+ * Wrapper plugins will override most methods to implement support for the
+ * native preset format of those wrapped plugins.
+ * One method that is useful to be overridden is gst_preset_get_property_names().
+ * With that one can control which properties are saved and in which order.
+ * When implementing support for read-only presets, one should set the vmethods
+ * for gst_preset_save_preset() and gst_preset_delete_preset() to %NULL.
+ * Applications can use gst_preset_is_editable() to check for that.
+ *
+ * The default implementation supports presets located in a system directory,
+ * application specific directory and in the users home directory. When getting
+ * a list of presets individual presets are read and overlaid in 1) system,
+ * 2) application and 3) user order. Whenever an earlier entry is newer, the
+ * later entries will be updated. Since 1.8 you can also provide extra paths
+ * where to find presets through the GST_PRESET_PATH environment variable.
+ * Presets found in those paths will be concidered as "app presets".
+ */
+/* FIXME:
+ * - non racyness
+ *   - we need to avoid two instances writing the preset file
+ *     -> flock(fileno()), http://www.ecst.csuchico.edu/~beej/guide/ipc/flock.html
+ *     -> open exclusive
+ *     -> better save the new file to a tempfile and then rename?
+ *   - we like to know when any other instance makes changes to the keyfile
+ *     - then ui can be updated
+ *     - and we make sure that we don't lose edits
+ *   -> its the same problem actually, once for inside a process, once system-
+ *      wide
+ *     - can we use a lock inside a names shared memory segment?
+ *
+ * - should there be a 'preset-list' property to get the preset list
+ *   (and to connect a notify:: to to listen for changes)
+ *   we could use gnome_vfs_monitor_add() to monitor the user preset_file.
+ *
+ * - should there be a 'preset-name' property so that we can set a preset via
+ *   gst-launch, or should we handle this with special syntax in gst-launch:
+ *   gst-launch element preset: property=value ...
+ *   - this would allow to have preset-bundles too (a preset on bins that
+ *     specifies presets for children

+/**
+ * SECTION:gstpromise
+ * @title: GstPromise
+ * @short_description: a miniobject for future/promise-like functionality
+ * @see_also:
+ *
+ * The #GstPromise object implements the container for values that may
+ * be available later. i.e. a Future or a Promise in
+ * https://en.wikipedia.org/wiki/Futures_and_promises
+ * As with all Future/Promise-like functionality, there is the concept of the
+ * producer of the value and the consumer of the value.
+ *
+ * A #GstPromise is created with gst_promise_new() by the consumer and passed
+ * to the producer to avoid thread safety issues with the change callback.
+ * A #GstPromise can be replied to with a value (or an error) by the producer
+ * with gst_promise_reply(). gst_promise_interrupt() is for the consumer to
+ * indicate to the producer that the value is not needed anymore and producing
+ * that value can stop.  The @GST_PROMISE_RESULT_EXPIRED state set by a call
+ * to gst_promise_expire() indicates to the consumer that a value will never
+ * be produced and is intended to be called by a third party that implements
+ * some notion of message handling such as #GstBus.
+ * A callback can also be installed at #GstPromise creation for
+ * result changes with gst_promise_new_with_change_func().
+ * The change callback can be used to chain #GstPromises's together as in the
+ * following example.
+ * |[
+ * const GstStructure *reply;
+ * GstPromise *p;
+ * if (gst_promise_wait (promise) != GST_PROMISE_RESULT_REPLIED)
+ *   return; // interrupted or expired value
+ * reply = gst_promise_get_reply (promise);
+ * if (error in reply)
+ *   return; // propagate error
+ * p = gst_promise_new_with_change_func (another_promise_change_func, user_data, notify);
+ * pass p to promise-using API
+ * ]|
+ *
+ * Each #GstPromise starts out with a #GstPromiseResult of
+ * %GST_PROMISE_RESULT_PENDING and only ever transitions once
+ * into one of the other #GstPromiseResult's.
+ *
+ * In order to support multi-threaded code, gst_promise_reply(),
+ * gst_promise_interrupt() and gst_promise_expire() may all be from
+ * different threads with some restrictions and the final result of the promise
+ * is whichever call is made first.  There are two restrictions on ordering:
+ *
+ * 1. That gst_promise_reply() and gst_promise_interrupt() cannot be called
+ * after gst_promise_expire()
+ * 2. That gst_promise_reply() and gst_promise_interrupt()
+ * cannot be called twice.
+ *
+ * The change function set with gst_promise_new_with_change_func() is
+ * called directly from either the gst_promise_reply(),
+ * gst_promise_interrupt() or gst_promise_expire() and can be called
+ * from an arbitrary thread.  #GstPromise using APIs can restrict this to
+ * a single thread or a subset of threads but that is entirely up to the API
+ * that uses #GstPromise.

+ * SECTION:gstquery
+ * @title: GstQuery
+ * @short_description: Provide functions to create queries, and to set and parse
+ *                     values in them.
+ * @see_also: #GstPad, #GstElement
+ *
+ * Queries can be performed on pads (gst_pad_query()) and elements
+ * (gst_element_query()). Please note that some queries might need a running
+ * pipeline to work.
+ *
+ * Queries can be created using the gst_query_new_*() functions.
+ * Query values can be set using gst_query_set_*(), and parsed using
+ * gst_query_parse_*() helpers.
+ *
+ * The following example shows how to query the duration of a pipeline:
+ * |[
+ *   GstQuery *query;
+ *   gboolean res;
+ *   query = gst_query_new_duration (GST_FORMAT_TIME);
+ *   res = gst_element_query (pipeline, query);
+ *   if (res) {
+ *     gint64 duration;
+ *     gst_query_parse_duration (query, NULL, &duration);
+ *     g_print ("duration = %"GST_TIME_FORMAT, GST_TIME_ARGS (duration));
+ *   } else {
+ *     g_print ("duration query failed...");
+ *   }
+ *   gst_query_unref (query);
+ * ]|

+/**
+ * SECTION:gstregistry
+ * @title: GstRegistry
+ * @short_description: Abstract base class for management of #GstPlugin objects
+ * @see_also: #GstPlugin, #GstPluginFeature
+ *
+ * One registry holds the metadata of a set of plugins.
+ *
+ * Design:
+ *
+ * The #GstRegistry object is a list of plugins and some functions for dealing
+ * with them. Each #GstPlugin is matched 1-1 with a file on disk, and may or may
+ * not be loaded at a given time.
+ *
+ * The primary source, at all times, of plugin information is each plugin file
+ * itself. Thus, if an application wants information about a particular plugin,
+ * or wants to search for a feature that satisfies given criteria, the primary
+ * means of doing so is to load every plugin and look at the resulting
+ * information that is gathered in the default registry. Clearly, this is a time
+ * consuming process, so we cache information in the registry file. The format
+ * and location of the cache file is internal to gstreamer.
+ *
+ * On startup, plugins are searched for in the plugin search path. The following
+ * locations are checked in this order:
+ *
+ * * location from --gst-plugin-path commandline option.
+ * * the GST_PLUGIN_PATH environment variable.
+ * * the GST_PLUGIN_SYSTEM_PATH environment variable.
+ * * default locations (if GST_PLUGIN_SYSTEM_PATH is not set).
+ *   Those default locations are:
+ *   `$XDG_DATA_HOME/gstreamer-$GST_API_VERSION/plugins/`
+ *   and `$prefix/libs/gstreamer-$GST_API_VERSION/`.
+ *   [$XDG_DATA_HOME](http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html) defaults to
+ *   `$HOME/.local/share`.
+ *
+ * The registry cache file is loaded from
+ * `$XDG_CACHE_HOME/gstreamer-$GST_API_VERSION/registry-$ARCH.bin`
+ * (where $XDG_CACHE_HOME defaults to `$HOME/.cache`) or the file listed in the `GST_REGISTRY`
+ * env var. One reason to change the registry location is for testing.
+ *
+ * For each plugin that is found in the plugin search path, there could be 3
+ * possibilities for cached information:
+ *
+ *   * the cache may not contain information about a given file.
+ *   * the cache may have stale information.
+ *   * the cache may have current information.
+ *
+ * In the first two cases, the plugin is loaded and the cache updated. In
+ * addition to these cases, the cache may have entries for plugins that are not
+ * relevant to the current process. These are marked as not available to the
+ * current process. If the cache is updated for whatever reason, it is marked
+ * dirty.
+ *
+ * A dirty cache is written out at the end of initialization. Each entry is
+ * checked to make sure the information is minimally valid. If not, the entry is
+ * simply dropped.
+ *
+ * ## Implementation notes:
+ *
+ * The "cache" and "registry" are different concepts and can represent
+ * different sets of plugins. For various reasons, at init time, the cache is
+ * stored in the default registry, and plugins not relevant to the current
+ * process are marked with the %GST_PLUGIN_FLAG_CACHED bit. These plugins are
+ * removed at the end of initialization.

+ * SECTION:gstsegment
+ * @title: GstSegment
+ * @short_description: Structure describing the configured region of interest
+ *                     in a media file.
+ * @see_also: #GstEvent
+ *
+ * This helper structure holds the relevant values for tracking the region of
+ * interest in a media file, called a segment.
+ *
+ * The structure can be used for two purposes:
+ *
+ *   * performing seeks (handling seek events)
+ *   * tracking playback regions (handling newsegment events)
+ *
+ * The segment is usually configured by the application with a seek event which
+ * is propagated upstream and eventually handled by an element that performs the seek.
+ *
+ * The configured segment is then propagated back downstream with a newsegment event.
+ * This information is then used to clip media to the segment boundaries.
+ *
+ * A segment structure is initialized with gst_segment_init(), which takes a #GstFormat
+ * that will be used as the format of the segment values. The segment will be configured
+ * with a start value of 0 and a stop/duration of -1, which is undefined. The default
+ * rate and applied_rate is 1.0.
+ *
+ * The public duration field contains the duration of the segment. When using
+ * the segment for seeking, the start and time members should normally be left
+ * to their default 0 value. The stop position is left to -1 unless explicitly
+ * configured to a different value after a seek event.
+ *
+ * The current position in the segment should be set by changing the position
+ * member in the structure.
+ *
+ * For elements that perform seeks, the current segment should be updated with the
+ * gst_segment_do_seek() and the values from the seek event. This method will update
+ * all the segment fields. The position field will contain the new playback position.
+ * If the start_type was different from GST_SEEK_TYPE_NONE, playback continues from
+ * the position position, possibly with updated flags or rate.
+ *
+ * For elements that want to use #GstSegment to track the playback region,
+ * update the segment fields with the information from the newsegment event.
+ * The gst_segment_clip() method can be used to check and clip
+ * the media data to the segment boundaries.
+ *
+ * For elements that want to synchronize to the pipeline clock, gst_segment_to_running_time()
+ * can be used to convert a timestamp to a value that can be used to synchronize
+ * to the clock. This function takes into account the base as well as
+ * any rate or applied_rate conversions.
+ *
+ * For elements that need to perform operations on media data in stream_time,
+ * gst_segment_to_stream_time() can be used to convert a timestamp and the segment
+ * info to stream time (which is always between 0 and the duration of the stream).
+ */
+
+/* FIXME 2.0: remove unused format parameter.
+ * Most of the methods in gstsegment.c take and extra GstFormat format, just to
+ * verify segment->format == format.
+ * See https://bugzilla.gnome.org/show_bug.cgi?id=788979

+ *                     faster but less accurate.
+ * @GST_SEEK_FLAG_SEGMENT: perform a segment seek.
+ * @GST_SEEK_FLAG_TRICKMODE: when doing fast forward or fast reverse playback, allow
+ *                     elements to skip frames instead of generating all
+ *                     frames. (Since 1.6)
+ * @GST_SEEK_FLAG_SNAP_BEFORE: go to a location before the requested position,
+ *                     if %GST_SEEK_FLAG_KEY_UNIT this means the keyframe at or before

+ *                     requested position.
+ * @GST_SEEK_FLAG_SNAP_NEAREST: go to a position near the requested position,
+ *                     if %GST_SEEK_FLAG_KEY_UNIT this means the keyframe closest
+ *                     to the requested position, if both keyframes are at an equal
+ *                     distance, behaves like %GST_SEEK_FLAG_SNAP_BEFORE.
+ * @GST_SEEK_FLAG_TRICKMODE_KEY_UNITS: when doing fast forward or fast reverse
+ *                     playback, request that elements only decode keyframes
+ *                     and skip all other content, for formats that have
+ *                     keyframes. (Since 1.6)
+ * @GST_SEEK_FLAG_TRICKMODE_NO_AUDIO: when doing fast forward or fast reverse
+ *                     playback, request that audio decoder elements skip
+ *                     decoding and output only gap events or silence. (Since 1.6)
+ * @GST_SEEK_FLAG_SKIP: Deprecated backward compatibility flag, replaced
+ *                     by %GST_SEEK_FLAG_TRICKMODE
+ *
+ * Flags to be used with gst_element_seek() or gst_event_new_seek(). All flags
+ * can be used together.
+ *
+ * A non flushing seek might take some time to perform as the currently
+ * playing data in the pipeline will not be cleared.
+ *
+ * An accurate seek might be slower for formats that don't have any indexes
+ * or timestamp markers in the stream. Specifying this flag might require a
+ * complete scan of the file in those cases.
+ *
+ * When performing a segment seek: after the playback of the segment completes,
+ * no EOS will be emitted by the element that performed the seek, but a
+ * %GST_MESSAGE_SEGMENT_DONE message will be posted on the bus by the element.
+ * When this message is posted, it is possible to send a new seek event to
+ * continue playback. With this seek method it is possible to perform seamless
+ * looping or simple linear editing.
+ *
+ * When doing fast forward (rate > 1.0) or fast reverse (rate < -1.0) trickmode
+ * playback, the %GST_SEEK_FLAG_TRICKMODE flag can be used to instruct decoders
+ * and demuxers to adjust the playback rate by skipping frames. This can improve
+ * performance and decrease CPU usage because not all frames need to be decoded.
+ *
+ * Beyond that, the %GST_SEEK_FLAG_TRICKMODE_KEY_UNITS flag can be used to
+ * request that decoders skip all frames except key units, and
+ * %GST_SEEK_FLAG_TRICKMODE_NO_AUDIO flags can be used to request that audio
+ * decoders do no decoding at all, and simple output silence.
+ *
+ * The %GST_SEEK_FLAG_SNAP_BEFORE flag can be used to snap to the previous
+ * relevant location, and the %GST_SEEK_FLAG_SNAP_AFTER flag can be used to
+ * select the next relevant location. If %GST_SEEK_FLAG_KEY_UNIT is specified,
+ * the relevant location is a keyframe. If both flags are specified, the nearest
+ * of these locations will be selected. If none are specified, the implementation is
+ * free to select whichever it wants.
+ *
+ * The before and after here are in running time, so when playing backwards,
+ * the next location refers to the one that will played in next, and not the
+ * one that is located after in the actual source stream.
+ *
+ * Also see part-seeking.txt in the GStreamer design documentation for more
+ * details on the meaning of these flags and the behaviour expected of
+ * elements that handle them.

+ *
+ * A #GstStream is a high-level object defining a stream of data which is, or
+ * can be, present in a #GstPipeline.
+ *
+ * It is defined by a unique identifier, a "Stream ID". A #GstStream does not
+ * automatically imply the stream is present within a pipeline or element.
+ *
+ * Any element that can introduce new streams in a pipeline should create the
+ * appropriate #GstStream object, and can convey that object via the
+ * %GST_EVENT_STREAM_START event and/or the #GstStreamCollection.
+ *
+ * Elements that do not modify the nature of the stream can add extra information
+ * on it (such as enrich the #GstCaps, or #GstTagList). This is typically done
+ * by parsing elements.

+/**
+ * SECTION:gststructure
+ * @title: GstStructure
+ * @short_description: Generic structure containing fields of names and values
+ * @see_also: #GstCaps, #GstMessage, #GstEvent, #GstQuery
+ *
+ * A #GstStructure is a collection of key/value pairs. The keys are expressed
+ * as GQuarks and the values can be of any GType.
+ *
+ * In addition to the key/value pairs, a #GstStructure also has a name. The name
+ * starts with a letter and can be filled by letters, numbers and any of "/-_.:".
+ *
+ * #GstStructure is used by various GStreamer subsystems to store information
+ * in a flexible and extensible way. A #GstStructure does not have a refcount
+ * because it usually is part of a higher level object such as #GstCaps,
+ * #GstMessage, #GstEvent, #GstQuery. It provides a means to enforce mutability
+ * using the refcount of the parent with the gst_structure_set_parent_refcount()
+ * method.
+ *
+ * A #GstStructure can be created with gst_structure_new_empty() or
+ * gst_structure_new(), which both take a name and an optional set of
+ * key/value pairs along with the types of the values.
+ *
+ * Field values can be changed with gst_structure_set_value() or
+ * gst_structure_set().
+ *
+ * Field values can be retrieved with gst_structure_get_value() or the more
+ * convenient gst_structure_get_*() functions.
+ *
+ * Fields can be removed with gst_structure_remove_field() or
+ * gst_structure_remove_fields().
+ *
+ * Strings in structures must be ASCII or UTF-8 encoded. Other encodings are
+ * not allowed. Strings may be %NULL however.
+ *
+ * Be aware that the current #GstCaps / #GstStructure serialization into string
+ * has limited support for nested #GstCaps / #GstStructure fields. It can only
+ * support one level of nesting. Using more levels will lead to unexpected
+ * behavior when using serialization features, such as gst_caps_to_string() or
+ * gst_value_serialize() and their counterparts.

+ * @short_description: Default clock that uses the current system time

+ *
+ * The GStreamer core provides a GstSystemClock based on the system time.
+ * Asynchronous callbacks are scheduled from an internal thread.
+ *
+ * Clock implementors are encouraged to subclass this systemclock as it
+ * implements the async notification.
+ *
+ * Subclasses can however override all of the important methods for sync and
+ * async notifications to implement their own callback methods or blocking
+ * wait operations.

+ * @title: GstTagsetter
+ * @short_description: Element interface that allows setting and retrieval
+ *                     of media metadata
+ *
+ * Element interface that allows setting of media metadata.
+ *
+ * Elements that support changing a stream's metadata will implement this
+ * interface. Examples of such elements are 'vorbisenc', 'theoraenc' and
+ * 'id3v2mux'.
+ *
+ * If you just want to retrieve metadata in your application then all you
+ * need to do is watch for tag messages on your pipeline's bus. This
+ * interface is only for setting metadata, not for extracting it. To set tags
+ * from the application, find tagsetter elements and set tags using e.g.
+ * gst_tag_setter_merge_tags() or gst_tag_setter_add_tags(). Also consider
+ * setting the #GstTagMergeMode that is used for tag events that arrive at the
+ * tagsetter element (default mode is to keep existing tags).
+ * The application should do that before the element goes to %GST_STATE_PAUSED.
+ *
+ * Elements implementing the #GstTagSetter interface often have to merge
+ * any tags received from upstream and the tags set by the application via
+ * the interface. This can be done like this:
+ *
+ * |[
+ * GstTagMergeMode merge_mode;
+ * const GstTagList *application_tags;
+ * const GstTagList *event_tags;
+ * GstTagSetter *tagsetter;
+ * GstTagList *result;
+ *
+ * tagsetter = GST_TAG_SETTER (element);
+ *
+ * merge_mode = gst_tag_setter_get_tag_merge_mode (tagsetter);
+ * application_tags = gst_tag_setter_get_tag_list (tagsetter);
+ * event_tags = (const GstTagList *) element->event_tags;
+ *
+ * GST_LOG_OBJECT (tagsetter, "merging tags, merge mode = %d", merge_mode);
+ * GST_LOG_OBJECT (tagsetter, "event tags: %" GST_PTR_FORMAT, event_tags);
+ * GST_LOG_OBJECT (tagsetter, "set   tags: %" GST_PTR_FORMAT, application_tags);
+ *
+ * result = gst_tag_list_merge (application_tags, event_tags, merge_mode);
+ *
+ * GST_LOG_OBJECT (tagsetter, "final tags: %" GST_PTR_FORMAT, result);

+/**
+ * SECTION:gsttask
+ * @title: GstTask
+ * @short_description: Abstraction of GStreamer streaming threads.
+ * @see_also: #GstElement, #GstPad
+ *
+ * #GstTask is used by #GstElement and #GstPad to provide the data passing
+ * threads in a #GstPipeline.
+ *
+ * A #GstPad will typically start a #GstTask to push or pull data to/from the
+ * peer pads. Most source elements start a #GstTask to push data. In some cases
+ * a demuxer element can start a #GstTask to pull data from a peer element. This
+ * is typically done when the demuxer can perform random access on the upstream
+ * peer element for improved performance.
+ *
+ * Although convenience functions exist on #GstPad to start/pause/stop tasks, it
+ * might sometimes be needed to create a #GstTask manually if it is not related to
+ * a #GstPad.
+ *
+ * Before the #GstTask can be run, it needs a #GRecMutex that can be set with
+ * gst_task_set_lock().
+ *
+ * The task can be started, paused and stopped with gst_task_start(), gst_task_pause()
+ * and gst_task_stop() respectively or with the gst_task_set_state() function.
+ *
+ * A #GstTask will repeatedly call the #GstTaskFunction with the user data
+ * that was provided when creating the task with gst_task_new(). While calling
+ * the function it will acquire the provided lock. The provided lock is released
+ * when the task pauses or stops.
+ *
+ * Stopping a task with gst_task_stop() will not immediately make sure the task is
+ * not running anymore. Use gst_task_join() to make sure the task is completely
+ * stopped and the thread is stopped.
+ *
+ * After creating a #GstTask, use gst_object_unref() to free its resources. This can
+ * only be done when the task is not running anymore.
+ *
+ * Task functions can send a #GstMessage to send out-of-band data to the
+ * application. The application can receive messages from the #GstBus in its
+ * mainloop.
+ *
+ * For debugging purposes, the task will configure its object name as the thread
+ * name on Linux. Please note that the object name should be configured before the
+ * task is started; changing the object name after the task has been started, has
+ * no effect on the thread name.

+ * SECTION:gsttoc
+ * @title: GstToc
+ * @short_description: Generic table of contents support
+ * @see_also: #GstStructure, #GstEvent, #GstMessage, #GstQuery
+ *
+ * #GstToc functions are used to create/free #GstToc and #GstTocEntry structures.
+ * Also they are used to convert #GstToc into #GstStructure and vice versa.
+ *
+ * #GstToc lets you to inform other elements in pipeline or application that playing
+ * source has some kind of table of contents (TOC). These may be chapters, editions,
+ * angles or other types. For example: DVD chapters, Matroska chapters or cue sheet
+ * TOC. Such TOC will be useful for applications to display instead of just a
+ * playlist.
+ *
+ * Using TOC is very easy. Firstly, create #GstToc structure which represents root
+ * contents of the source. You can also attach TOC-specific tags to it. Then fill
+ * it with #GstTocEntry entries by appending them to the #GstToc using
+ * gst_toc_append_entry(), and appending subentries to a #GstTocEntry using
+ * gst_toc_entry_append_sub_entry().
+ *
+ * Note that root level of the TOC can contain only either editions or chapters. You
+ * should not mix them together at the same level. Otherwise you will get serialization
+ * /deserialization errors. Make sure that no one of the entries has negative start and
+ *  stop values.
+ *
+ * Use gst_event_new_toc() to create a new TOC #GstEvent, and gst_event_parse_toc() to
+ * parse received TOC event. Use gst_event_new_toc_select() to create a new TOC select #GstEvent,
+ * and gst_event_parse_toc_select() to parse received TOC select event. The same rule for
+ * the #GstMessage: gst_message_new_toc() to create new TOC #GstMessage, and
+ * gst_message_parse_toc() to parse received TOC message.
+ *
+ * TOCs can have global scope or current scope. Global scope TOCs contain
+ * all entries that can possibly be selected using a toc select event, and
+ * are what an application is usually interested in. TOCs with current scope
+ * only contain the parts of the TOC relevant to the currently selected/playing
+ * stream; the current scope TOC is used by downstream elements such as muxers
+ * to write correct TOC entries when transcoding files, for example. When
+ * playing a DVD, the global TOC would contain a hierarchy of all titles,
+ * chapters and angles, for example, while the current TOC would only contain
+ * the chapters for the currently playing title if playback of a specific
+ * title was requested.
+ *
+ * Applications and plugins should not rely on TOCs having a certain kind of
+ * structure, but should allow for different alternatives. For example, a
+ * simple CUE sheet embedded in a file may be presented as a flat list of
+ * track entries, or could have a top-level edition node (or some other
+ * alternative type entry) with track entries underneath that node; or even
+ * multiple top-level edition nodes (or some other alternative type entries)
+ * each with track entries underneath, in case the source file has extracted
+ * a track listing from different sources).

+ *
+ * An application can use the following functions to quickly get an element
+ * that handles the given URI for reading or writing

+ * Source and Sink plugins should implement this interface when possible.

+The files
+
+ asnprintf.c
+ printf-args.c
+ printf-args.h
+ printf-parse.c
+ printf-parse.h
+ vasnprintf.c
+ vasnprintf.h
+
+are taken from the vasnprintf module of the GNUlib package, which can
+be found at:
+
+ http://www.gnu.org/software/gnulib/
+
+All files have been modified to include g-gnulib.h.
+
+vasnprintf.c has also been modified to include support for long long
+printing if the system printf doesn't. This code is protected by
+#ifndef HAVE_LONG_LONG_FORMAT.
+
+Code has been added to printf-args.[ch], printf-parse.c and vasnprintf.c
+to support printing of __int64 values with the I64 format modifier. This
+is protected by #ifdef HAVE_INT64_AND_I64.
+
+The files
+
+ printf.h
+ printf.c
+ g-gnulib.h
+
+have been written by me. printf.[hc] contain implementations of the
+remaining functions in the printf family based on vasnprintf.
+g-gnulib.h is included by all source files in order to move all
+exported functions to the _g_gnulib namespace, replace malloc by
+g_malloc and make sure that snprintf is only used if it implements
+C99 return value semantics.
+
+Matthias Clasen
+November 1, 2003
+
+-----
+
+GStreamer modifications
+
+This was imported from GLib's gnulib subdirectory.
+
+g-gnulib.h and _g_gnulib namespace has been changed to gst-printf.h and
+__gst_printf namespace for GStreamer. Also #define HAVE_SNPRINTF 0 has
+been changed to #undef HAVE_SNPRINTF, and HAVE_ALLOCA has been replaced
+by an #if defined(alloca) || defined(GLIB_HAVE_ALLOCA_H)
+
+printf-extension.[ch] were added to provide support for custom pointer
+arguments (e.g. caps, events, etc.)
+
+Files have also been indented with gst-indent, so this is basically a
+permanent fork and any patches will have to be merged manually.
+
+March 30, 2013.

+GStreamer is a streaming media framework
+
+ 
+GStreamer is a streaming media framework that allows the construction of
+graphs of elements which operate on media data.
+Applications using this library can do anything from real-time sound processing
+over playing video to capturing audio, video, and even other types of media
+data.
+Its architecture allows for adding new data types or processing capabilities
+simply by installing new plug-ins.
+GStreamer is the core module, containing libraries, headers, the basic object
+hierarchy, and a set of media-agnostic core elements.

+/**
+ * SECTION:gstadapter
+ * @title: GstAdapter
+ * @short_description: adapts incoming data on a sink pad into chunks of N bytes
+ *
+ * This class is for elements that receive buffers in an undesired size.
+ * While for example raw video contains one image per buffer, the same is not
+ * true for a lot of other formats, especially those that come directly from
+ * a file. So if you have undefined buffer sizes and require a specific size,
+ * this object is for you.
+ *
+ * An adapter is created with gst_adapter_new(). It can be freed again with
+ * g_object_unref().
+ *
+ * The theory of operation is like this: All buffers received are put
+ * into the adapter using gst_adapter_push() and the data is then read back
+ * in chunks of the desired size using gst_adapter_map()/gst_adapter_unmap()
+ * and/or gst_adapter_copy(). After the data has been processed, it is freed
+ * using gst_adapter_unmap().
+ *
+ * Other methods such as gst_adapter_take() and gst_adapter_take_buffer()
+ * combine gst_adapter_map() and gst_adapter_unmap() in one method and are
+ * potentially more convenient for some use cases.
+ *
+ * For example, a sink pad's chain function that needs to pass data to a library
+ * in 512-byte chunks could be implemented like this:
+ * |[
+ * static GstFlowReturn
+ * sink_pad_chain (GstPad *pad, GstObject *parent, GstBuffer *buffer)
+ * {
+ *   MyElement *this;
+ *   GstAdapter *adapter;
+ *   GstFlowReturn ret = GST_FLOW_OK;
+ *
+ *   this = MY_ELEMENT (parent);
+ *
+ *   adapter = this->adapter;
+ *
+ *   // put buffer into adapter
+ *   gst_adapter_push (adapter, buffer);
+ *
+ *   // while we can read out 512 bytes, process them
+ *   while (gst_adapter_available (adapter) >= 512 && ret == GST_FLOW_OK) {
+ *     const guint8 *data = gst_adapter_map (adapter, 512);
+ *     // use flowreturn as an error value
+ *     ret = my_library_foo (data);
+ *     gst_adapter_unmap (adapter);
+ *     gst_adapter_flush (adapter, 512);
+ *   }
+ *   return ret;
+ * }
+ * ]|
+ *
+ * For another example, a simple element inside GStreamer that uses #GstAdapter
+ * is the libvisual element.
+ *
+ * An element using #GstAdapter in its sink pad chain function should ensure that
+ * when the FLUSH_STOP event is received, that any queued data is cleared using
+ * gst_adapter_clear(). Data should also be cleared or processed on EOS and
+ * when changing state from %GST_STATE_PAUSED to %GST_STATE_READY.
+ *
+ * Also check the GST_BUFFER_FLAG_DISCONT flag on the buffer. Some elements might
+ * need to clear the adapter after a discontinuity.
+ *
+ * The adapter will keep track of the timestamps of the buffers
+ * that were pushed. The last seen timestamp before the current position
+ * can be queried with gst_adapter_prev_pts(). This function can
+ * optionally return the number of bytes between the start of the buffer that
+ * carried the timestamp and the current adapter position. The distance is
+ * useful when dealing with, for example, raw audio samples because it allows
+ * you to calculate the timestamp of the current adapter position by using the
+ * last seen timestamp and the amount of bytes since.  Additionally, the
+ * gst_adapter_prev_pts_at_offset() can be used to determine the last
+ * seen timestamp at a particular offset in the adapter.
+ *
+ * The adapter will also keep track of the offset of the buffers
+ * (#GST_BUFFER_OFFSET) that were pushed. The last seen offset before the
+ * current position can be queried with gst_adapter_prev_offset(). This function
+ * can optionally return the number of bytes between the start of the buffer
+ * that carried the offset and the current adapter position.
+ *
+ * Additionally the adapter also keeps track of the PTS, DTS and buffer offset
+ * at the last discontinuity, which can be retrieved with
+ * gst_adapter_pts_at_discont(), gst_adapter_dts_at_discont() and
+ * gst_adapter_offset_at_discont(). The number of bytes that were consumed
+ * since then can be queried with gst_adapter_distance_from_discont().
+ *
+ * A last thing to note is that while #GstAdapter is pretty optimized,
+ * merging buffers still might be an operation that requires a malloc() and
+ * memcpy() operation, and these operations are not the fastest. Because of
+ * this, some functions like gst_adapter_available_fast() are provided to help
+ * speed up such cases should you want to. To avoid repeated memory allocations,
+ * gst_adapter_copy() can be used to copy data into a (statically allocated)
+ * user provided buffer.
+ *
+ * #GstAdapter is not MT safe. All operations on an adapter must be serialized by
+ * the caller. This is not normally a problem, however, as the normal use case
+ * of #GstAdapter is inside one pad's chain function, in which case access is
+ * serialized via the pad's STREAM_LOCK.
+ *
+ * Note that gst_adapter_push() takes ownership of the buffer passed. Use
+ * gst_buffer_ref() before pushing it into the adapter if you still want to
+ * access the buffer later. The adapter will never modify the data in the
+ * buffer pushed in it.

+ * SECTION: gstaggregator
+ * @title: GstAggregator
+ * @short_description: Base class for mixers and muxers, manages a set of input
+ *     pads and aggregates their streams
+ * @see_also: gstcollectpads for historical reasons.
+ *
+ * Manages a set of pads with the purpose of aggregating their buffers.
+ * Control is given to the subclass when all pads have data.
+ *
+ *  * Base class for mixers and muxers. Subclasses should at least implement
+ *    the #GstAggregatorClass.aggregate() virtual method.
+ *
+ *  * Installs a #GstPadChainFunction, a #GstPadEventFullFunction and a
+ *    #GstPadQueryFunction to queue all serialized data packets per sink pad.
+ *    Subclasses should not overwrite those, but instead implement
+ *    #GstAggregatorClass.sink_event() and #GstAggregatorClass.sink_query() as
+ *    needed.
+ *
+ *  * When data is queued on all pads, the aggregate vmethod is called.
+ *
+ *  * One can peek at the data on any given GstAggregatorPad with the
+ *    gst_aggregator_pad_peek_buffer () method, and remove it from the pad
+ *    with the gst_aggregator_pad_pop_buffer () method. When a buffer
+ *    has been taken with pop_buffer (), a new buffer can be queued
+ *    on that pad.
+ *
+ *  * If the subclass wishes to push a buffer downstream in its aggregate
+ *    implementation, it should do so through the
+ *    gst_aggregator_finish_buffer () method. This method will take care
+ *    of sending and ordering mandatory events such as stream start, caps
+ *    and segment.
+ *
+ *  * Same goes for EOS events, which should not be pushed directly by the
+ *    subclass, it should instead return GST_FLOW_EOS in its aggregate
+ *    implementation.
+ *
+ *  * Note that the aggregator logic regarding gap event handling is to turn
+ *    these into gap buffers with matching PTS and duration. It will also
+ *    flag these buffers with GST_BUFFER_FLAG_GAP and GST_BUFFER_FLAG_DROPPABLE
+ *    to ease their identification and subsequent processing.
+ *
+ *  * Subclasses must use (a subclass of) #GstAggregatorPad for both their
+ *    sink and source pads.
+ *    See gst_element_class_add_static_pad_template_with_gtype().
+ *
+ * This class used to live in gst-plugins-bad and was moved to core.
+ *
+ * Since: 1.14

+ *                  clipping it and translating it to the current segment falls
+ *                  on the subclass. The function should use the segment of data

+ *                  Called when a query is received on a sink pad, the subclass

+ * @src_query:      Optional.
+ *                  Called when a query is received on the src pad, the subclass
+ *                  should always chain up.
+ * @src_activate:   Optional.
+ *                  Called when the src pad is activated, it will start/stop its
+ *                  pad task right after that call.
+ * @aggregate:      Mandatory.
+ *                  Called when buffers are queued on all sinkpads. Classes
+ *                  should iterate the GstElement->sinkpads and peek or steal
+ *                  buffers from the #GstAggregatorPads. If the subclass returns
+ *                  GST_FLOW_EOS, sending of the eos event will be taken care
+ *                  of. Once / if a buffer has been constructed from the
+ *                  aggregated buffers, the subclass should call _finish_buffer.
+ * @stop:           Optional.
+ *                  Called when the element goes from PAUSED to READY.
+ *                  The subclass should free all resources and reset its state.
+ * @start:          Optional.
+ *                  Called when the element goes from READY to PAUSED.
+ *                  The subclass should get ready to process
+ *                  aggregated buffers.
+ * @get_next_time:  Optional.
+ *                  Called when the element needs to know the running time of the next
+ *                  rendered buffer for live pipelines. This causes deadline
+ *                  based aggregation to occur. Defaults to returning
+ *                  GST_CLOCK_TIME_NONE causing the element to wait for buffers
+ *                  on all sink pads before aggregating.
+ * @update_src_caps: Lets subclasses update the #GstCaps representing
+ *                   the src pad caps before usage.  The result should end up
+ *                   in @ret. Return %GST_AGGREGATOR_FLOW_NEED_DATA to indicate that the
+ *                   element needs more information (caps, a buffer, etc) to
+ *                   choose the correct caps. Should return ANY caps if the
+ *                   stream has not caps at all.
+ * @fixate_src_caps: Optional.
+ *                   Fixate and return the src pad caps provided.  The function takes
+ *                   ownership of @caps and returns a fixated version of
+ *                   @caps. @caps is not guaranteed to be writable.
+ * @negotiated_src_caps: Optional.
+ *                       Notifies subclasses what caps format has been negotiated
+ * @decide_allocation: Optional.
+ *                     Allows the subclass to influence the allocation choices.
+ *                     Setup the allocation parameters for allocating output
+ *                     buffers. The passed in query contains the result of the
+ *                     downstream allocation query.
+ *
+ * The aggregator base class will handle in a thread-safe way all manners of
+ * concurrent flushes, seeks, pad additions and removals, leaving to the
+ * subclass the responsibility of clipping buffers, and aggregating buffers in
+ * the way the implementor sees fit.
+ *
+ * It will also take care of event ordering (stream-start, segment, eos).
+ *
+ * Basically, a simple implementation will override @aggregate, and call
+ * _finish_buffer from inside that function.

+/**
+ * SECTION:gstbaseparse
+ * @title: GstBaseParse
+ * @short_description: Base class for stream parsers
+ * @see_also: #GstBaseTransform
+ *
+ * This base class is for parser elements that process data and splits it
+ * into separate audio/video/whatever frames.
+ *
+ * It provides for:
+ *
+ *   * provides one sink pad and one source pad
+ *   * handles state changes
+ *   * can operate in pull mode or push mode
+ *   * handles seeking in both modes
+ *   * handles events (SEGMENT/EOS/FLUSH)
+ *   * handles queries (POSITION/DURATION/SEEKING/FORMAT/CONVERT)
+ *   * handles flushing
+ *
+ * The purpose of this base class is to provide the basic functionality of
+ * a parser and share a lot of rather complex code.
+ *
+ * # Description of the parsing mechanism:
+ *
+ * ## Set-up phase
+ *
+ *  * #GstBaseParse calls @start to inform subclass that data processing is
+ *    about to start now.
+ *
+ *  * #GstBaseParse class calls @set_sink_caps to inform the subclass about
+ *    incoming sinkpad caps. Subclass could already set the srcpad caps
+ *    accordingly, but this might be delayed until calling
+ *    gst_base_parse_finish_frame() with a non-queued frame.
+ *
+ *  * At least at this point subclass needs to tell the #GstBaseParse class
+ *    how big data chunks it wants to receive (min_frame_size). It can do
+ *    this with gst_base_parse_set_min_frame_size().
+ *
+ *  * #GstBaseParse class sets up appropriate data passing mode (pull/push)
+ *    and starts to process the data.
+ *
+ * ## Parsing phase
+ *
+ *  * #GstBaseParse gathers at least min_frame_size bytes of data either
+ *    by pulling it from upstream or collecting buffers in an internal
+ *    #GstAdapter.
+ *
+ *  * A buffer of (at least) min_frame_size bytes is passed to subclass with
+ *    @handle_frame. Subclass checks the contents and can optionally
+ *    return GST_FLOW_OK along with an amount of data to be skipped to find
+ *    a valid frame (which will result in a subsequent DISCONT).
+ *    If, otherwise, the buffer does not hold a complete frame,
+ *    @handle_frame can merely return and will be called again when additional
+ *    data is available.  In push mode this amounts to an
+ *    additional input buffer (thus minimal additional latency), in pull mode
+ *    this amounts to some arbitrary reasonable buffer size increase.
+ *    Of course, gst_base_parse_set_min_frame_size() could also be used if a
+ *    very specific known amount of additional data is required.
+ *    If, however, the buffer holds a complete valid frame, it can pass
+ *    the size of this frame to gst_base_parse_finish_frame().
+ *    If acting as a converter, it can also merely indicate consumed input data
+ *    while simultaneously providing custom output data.
+ *    Note that baseclass performs some processing (such as tracking
+ *    overall consumed data rate versus duration) for each finished frame,
+ *    but other state is only updated upon each call to @handle_frame
+ *    (such as tracking upstream input timestamp).
+ *
+ *    Subclass is also responsible for setting the buffer metadata
+ *    (e.g. buffer timestamp and duration, or keyframe if applicable).
+ *    (although the latter can also be done by #GstBaseParse if it is
+ *    appropriately configured, see below).  Frame is provided with
+ *    timestamp derived from upstream (as much as generally possible),
+ *    duration obtained from configuration (see below), and offset
+ *    if meaningful (in pull mode).
+ *
+ *    Note that @check_valid_frame might receive any small
+ *    amount of input data when leftover data is being drained (e.g. at EOS).
+ *
+ *  * As part of finish frame processing,
+ *    just prior to actually pushing the buffer in question,
+ *    it is passed to @pre_push_frame which gives subclass yet one
+ *    last chance to examine buffer metadata, or to send some custom (tag)
+ *    events, or to perform custom (segment) filtering.
+ *
+ *  * During the parsing process #GstBaseParseClass will handle both srcpad
+ *    and sinkpad events. They will be passed to subclass if @event or
+ *    @src_event callbacks have been provided.
+ *
+ * ## Shutdown phase
+ *
+ * * #GstBaseParse class calls @stop to inform the subclass that data
+ *   parsing will be stopped.
+ *
+ * Subclass is responsible for providing pad template caps for
+ * source and sink pads. The pads need to be named "sink" and "src". It also
+ * needs to set the fixed caps on srcpad, when the format is ensured (e.g.
+ * when base class calls subclass' @set_sink_caps function).
+ *
+ * This base class uses %GST_FORMAT_DEFAULT as a meaning of frames. So,
+ * subclass conversion routine needs to know that conversion from
+ * %GST_FORMAT_TIME to %GST_FORMAT_DEFAULT must return the
+ * frame number that can be found from the given byte position.
+ *
+ * #GstBaseParse uses subclasses conversion methods also for seeking (or
+ * otherwise uses its own default one, see also below).
+ *
+ * Subclass @start and @stop functions will be called to inform the beginning
+ * and end of data processing.
+ *
+ * Things that subclass need to take care of:
+ *
+ * * Provide pad templates
+ * * Fixate the source pad caps when appropriate
+ * * Inform base class how big data chunks should be retrieved. This is
+ *   done with gst_base_parse_set_min_frame_size() function.
+ * * Examine data chunks passed to subclass with @handle_frame and pass
+ *   proper frame(s) to gst_base_parse_finish_frame(), and setting src pad
+ *   caps and timestamps on frame.
+ * * Provide conversion functions
+ * * Update the duration information with gst_base_parse_set_duration()
+ * * Optionally passthrough using gst_base_parse_set_passthrough()
+ * * Configure various baseparse parameters using
+ *   gst_base_parse_set_average_bitrate(), gst_base_parse_set_syncable()
+ *   and gst_base_parse_set_frame_rate().
+ *
+ * * In particular, if subclass is unable to determine a duration, but
+ *   parsing (or specs) yields a frames per seconds rate, then this can be
+ *   provided to #GstBaseParse to enable it to cater for
+ *   buffer time metadata (which will be taken from upstream as much as
+ *   possible). Internally keeping track of frame durations and respective
+ *   sizes that have been pushed provides #GstBaseParse with an estimated
+ *   bitrate. A default @convert (used if not overridden) will then use these
+ *   rates to perform obvious conversions.  These rates are also used to
+ *   update (estimated) duration at regular frame intervals.

+/**
+ * SECTION:gstbasesink
+ * @title: GstBaseSink
+ * @short_description: Base class for sink elements
+ * @see_also: #GstBaseTransform, #GstBaseSrc
+ *
+ * #GstBaseSink is the base class for sink elements in GStreamer, such as
+ * xvimagesink or filesink. It is a layer on top of #GstElement that provides a
+ * simplified interface to plugin writers. #GstBaseSink handles many details
+ * for you, for example: preroll, clock synchronization, state changes,
+ * activation in push or pull mode, and queries.
+ *
+ * In most cases, when writing sink elements, there is no need to implement
+ * class methods from #GstElement or to set functions on pads, because the
+ * #GstBaseSink infrastructure should be sufficient.
+ *
+ * #GstBaseSink provides support for exactly one sink pad, which should be
+ * named "sink". A sink implementation (subclass of #GstBaseSink) should
+ * install a pad template in its class_init function, like so:
+ * |[
+ * static void
+ * my_element_class_init (GstMyElementClass *klass)
+ * {
+ *   GstElementClass *gstelement_class = GST_ELEMENT_CLASS (klass);
+ *
+ *   // sinktemplate should be a #GstStaticPadTemplate with direction
+ *   // %GST_PAD_SINK and name "sink"
+ *   gst_element_class_add_static_pad_template (gstelement_class, &sinktemplate);
+ *
+ *   gst_element_class_set_static_metadata (gstelement_class,
+ *       "Sink name",
+ *       "Sink",
+ *       "My Sink element",
+ *       "The author ");
+ * }
+ * ]|
+ *
+ * #GstBaseSink will handle the prerolling correctly. This means that it will
+ * return %GST_STATE_CHANGE_ASYNC from a state change to PAUSED until the first
+ * buffer arrives in this element. The base class will call the
+ * #GstBaseSinkClass.preroll() vmethod with this preroll buffer and will then
+ * commit the state change to the next asynchronously pending state.
+ *
+ * When the element is set to PLAYING, #GstBaseSink will synchronise on the
+ * clock using the times returned from #GstBaseSinkClass.get_times(). If this
+ * function returns %GST_CLOCK_TIME_NONE for the start time, no synchronisation
+ * will be done. Synchronisation can be disabled entirely by setting the object
+ * #GstBaseSink:sync property to %FALSE.
+ *
+ * After synchronisation the virtual method #GstBaseSinkClass.render() will be
+ * called. Subclasses should minimally implement this method.
+ *
+ * Subclasses that synchronise on the clock in the #GstBaseSinkClass.render()
+ * method are supported as well. These classes typically receive a buffer in
+ * the render method and can then potentially block on the clock while
+ * rendering. A typical example is an audiosink.
+ * These subclasses can use gst_base_sink_wait_preroll() to perform the
+ * blocking wait.
+ *
+ * Upon receiving the EOS event in the PLAYING state, #GstBaseSink will wait
+ * for the clock to reach the time indicated by the stop time of the last
+ * #GstBaseSinkClass.get_times() call before posting an EOS message. When the
+ * element receives EOS in PAUSED, preroll completes, the event is queued and an
+ * EOS message is posted when going to PLAYING.
+ *
+ * #GstBaseSink will internally use the %GST_EVENT_SEGMENT events to schedule
+ * synchronisation and clipping of buffers. Buffers that fall completely outside
+ * of the current segment are dropped. Buffers that fall partially in the
+ * segment are rendered (and prerolled). Subclasses should do any subbuffer
+ * clipping themselves when needed.
+ *
+ * #GstBaseSink will by default report the current playback position in
+ * %GST_FORMAT_TIME based on the current clock time and segment information.
+ * If no clock has been set on the element, the query will be forwarded
+ * upstream.
+ *
+ * The #GstBaseSinkClass.set_caps() function will be called when the subclass
+ * should configure itself to process a specific media type.
+ *
+ * The #GstBaseSinkClass.start() and #GstBaseSinkClass.stop() virtual methods
+ * will be called when resources should be allocated. Any
+ * #GstBaseSinkClass.preroll(), #GstBaseSinkClass.render() and
+ * #GstBaseSinkClass.set_caps() function will be called between the
+ * #GstBaseSinkClass.start() and #GstBaseSinkClass.stop() calls.
+ *
+ * The #GstBaseSinkClass.event() virtual method will be called when an event is
+ * received by #GstBaseSink. Normally this method should only be overridden by
+ * very specific elements (such as file sinks) which need to handle the
+ * newsegment event specially.
+ *
+ * The #GstBaseSinkClass.unlock() method is called when the elements should
+ * unblock any blocking operations they perform in the
+ * #GstBaseSinkClass.render() method. This is mostly useful when the
+ * #GstBaseSinkClass.render() method performs a blocking write on a file
+ * descriptor, for example.
+ *
+ * The #GstBaseSink:max-lateness property affects how the sink deals with
+ * buffers that arrive too late in the sink. A buffer arrives too late in the
+ * sink when the presentation time (as a combination of the last segment, buffer
+ * timestamp and element base_time) plus the duration is before the current
+ * time of the clock.
+ * If the frame is later than max-lateness, the sink will drop the buffer
+ * without calling the render method.
+ * This feature is disabled if sync is disabled, the
+ * #GstBaseSinkClass.get_times() method does not return a valid start time or
+ * max-lateness is set to -1 (the default).
+ * Subclasses can use gst_base_sink_set_max_lateness() to configure the
+ * max-lateness value.
+ *
+ * The #GstBaseSink:qos property will enable the quality-of-service features of
+ * the basesink which gather statistics about the real-time performance of the
+ * clock synchronisation. For each buffer received in the sink, statistics are
+ * gathered and a QOS event is sent upstream with these numbers. This
+ * information can then be used by upstream elements to reduce their processing
+ * rate, for example.
+ *
+ * The #GstBaseSink:async property can be used to instruct the sink to never
+ * perform an ASYNC state change. This feature is mostly usable when dealing
+ * with non-synchronized streams or sparse streams.

+ * GstBaseSinkClass:

+ * @set_caps: Notify subclass of changed caps
+ * @fixate: Only useful in pull mode. Implement if you have
+ *     ideas about what should be the default values for the caps you support.
+ * @activate_pull: Subclasses should override this when they can provide an
+ *     alternate method of spawning a thread to drive the pipeline in pull mode.
+ *     Should start or stop the pulling thread, depending on the value of the
+ *     "active" argument. Called after actually activating the sink pad in pull
+ *     mode. The default implementation starts a task on the sink pad.
+ * @get_times: Called to get the start and end times for synchronising
+ *     the passed buffer to the clock
+ * @propose_allocation: configure the allocation query
+ * @start: Start processing. Ideal for opening resources in the subclass
+ * @stop: Stop processing. Subclasses should use this to close resources.
+ * @unlock: Unlock any pending access to the resource. Subclasses should
+ *     unblock any blocked function ASAP and call gst_base_sink_wait_preroll()
+ * @unlock_stop: Clear the previous unlock request. Subclasses should clear
+ *     any state they set during #GstBaseSinkClass.unlock(), and be ready to
+ *     continue where they left off after gst_base_sink_wait_preroll(),
+ *     gst_base_sink_wait() or gst_wait_sink_wait_clock() return or
+ *     #GstBaseSinkClass.render() is called again.
+ * @query: perform a #GstQuery on the element.
+ * @event: Override this to handle events arriving on the sink pad
+ * @wait_event: Override this to implement custom logic to wait for the event
+ *     time (for events like EOS and GAP). Subclasses should always first
+ *     chain up to the default implementation.
+ * @prepare: Called to prepare the buffer for @render and @preroll. This
+ *     function is called before synchronisation is performed.
+ * @prepare_list: Called to prepare the buffer list for @render_list. This
+ *     function is called before synchronisation is performed.
+ * @preroll: Called to present the preroll buffer if desired.
+ * @render: Called when a buffer should be presented or output, at the
+ *     correct moment if the #GstBaseSink has been set to sync to the clock.
+ * @render_list: Same as @render but used with buffer lists instead of
+ *     buffers.
+ *
+ * Subclasses can override any of the available virtual methods or not, as
+ * needed. At the minimum, the @render method should be overridden to
+ * output/present buffers.

+/**
+ * SECTION:gstbasesrc
+ * @title: GstBaseSrc
+ * @short_description: Base class for getrange based source elements
+ * @see_also: #GstPushSrc, #GstBaseTransform, #GstBaseSink
+ *
+ * This is a generic base class for source elements. The following
+ * types of sources are supported:
+ *
+ *   * random access sources like files
+ *   * seekable sources
+ *   * live sources
+ *
+ * The source can be configured to operate in any #GstFormat with the
+ * gst_base_src_set_format() method. The currently set format determines
+ * the format of the internal #GstSegment and any %GST_EVENT_SEGMENT
+ * events. The default format for #GstBaseSrc is %GST_FORMAT_BYTES.
+ *
+ * #GstBaseSrc always supports push mode scheduling. If the following
+ * conditions are met, it also supports pull mode scheduling:
+ *
+ *   * The format is set to %GST_FORMAT_BYTES (default).
+ *   * #GstBaseSrcClass.is_seekable() returns %TRUE.
+ *
+ * If all the conditions are met for operating in pull mode, #GstBaseSrc is
+ * automatically seekable in push mode as well. The following conditions must
+ * be met to make the element seekable in push mode when the format is not
+ * %GST_FORMAT_BYTES:
+ *
+ * * #GstBaseSrcClass.is_seekable() returns %TRUE.
+ * * #GstBaseSrcClass.query() can convert all supported seek formats to the
+ *   internal format as set with gst_base_src_set_format().
+ * * #GstBaseSrcClass.do_seek() is implemented, performs the seek and returns
+ *    %TRUE.
+ *
+ * When the element does not meet the requirements to operate in pull mode, the
+ * offset and length in the #GstBaseSrcClass.create() method should be ignored.
+ * It is recommended to subclass #GstPushSrc instead, in this situation. If the
+ * element can operate in pull mode but only with specific offsets and
+ * lengths, it is allowed to generate an error when the wrong values are passed
+ * to the #GstBaseSrcClass.create() function.
+ *
+ * #GstBaseSrc has support for live sources. Live sources are sources that when
+ * paused discard data, such as audio or video capture devices. A typical live
+ * source also produces data at a fixed rate and thus provides a clock to publish
+ * this rate.
+ * Use gst_base_src_set_live() to activate the live source mode.
+ *
+ * A live source does not produce data in the PAUSED state. This means that the
+ * #GstBaseSrcClass.create() method will not be called in PAUSED but only in
+ * PLAYING. To signal the pipeline that the element will not produce data, the
+ * return value from the READY to PAUSED state will be
+ * %GST_STATE_CHANGE_NO_PREROLL.
+ *
+ * A typical live source will timestamp the buffers it creates with the
+ * current running time of the pipeline. This is one reason why a live source
+ * can only produce data in the PLAYING state, when the clock is actually
+ * distributed and running.
+ *
+ * Live sources that synchronize and block on the clock (an audio source, for
+ * example) can use gst_base_src_wait_playing() when the
+ * #GstBaseSrcClass.create() function was interrupted by a state change to
+ * PAUSED.
+ *
+ * The #GstBaseSrcClass.get_times() method can be used to implement pseudo-live
+ * sources. It only makes sense to implement the #GstBaseSrcClass.get_times()
+ * function if the source is a live source. The #GstBaseSrcClass.get_times()
+ * function should return timestamps starting from 0, as if it were a non-live
+ * source. The base class will make sure that the timestamps are transformed
+ * into the current running_time. The base source will then wait for the
+ * calculated running_time before pushing out the buffer.
+ *
+ * For live sources, the base class will by default report a latency of 0.
+ * For pseudo live sources, the base class will by default measure the difference
+ * between the first buffer timestamp and the start time of get_times and will
+ * report this value as the latency.
+ * Subclasses should override the query function when this behaviour is not
+ * acceptable.
+ *
+ * There is only support in #GstBaseSrc for exactly one source pad, which
+ * should be named "src". A source implementation (subclass of #GstBaseSrc)
+ * should install a pad template in its class_init function, like so:
+ * |[
+ * static void
+ * my_element_class_init (GstMyElementClass *klass)
+ * {
+ *   GstElementClass *gstelement_class = GST_ELEMENT_CLASS (klass);
+ *   // srctemplate should be a #GstStaticPadTemplate with direction
+ *   // %GST_PAD_SRC and name "src"
+ *   gst_element_class_add_static_pad_template (gstelement_class, &srctemplate);
+ *
+ *   gst_element_class_set_static_metadata (gstelement_class,
+ *      "Source name",
+ *      "Source",
+ *      "My Source element",
+ *      "The author ");
+ * }
+ * ]|
+ *
+ * ## Controlled shutdown of live sources in applications
+ *
+ * Applications that record from a live source may want to stop recording
+ * in a controlled way, so that the recording is stopped, but the data
+ * already in the pipeline is processed to the end (remember that many live
+ * sources would go on recording forever otherwise). For that to happen the
+ * application needs to make the source stop recording and send an EOS
+ * event down the pipeline. The application would then wait for an
+ * EOS message posted on the pipeline's bus to know when all data has
+ * been processed and the pipeline can safely be stopped.
+ *
+ * An application may send an EOS event to a source element to make it
+ * perform the EOS logic (send EOS event downstream or post a
+ * %GST_MESSAGE_SEGMENT_DONE on the bus). This can typically be done
+ * with the gst_element_send_event() function on the element or its parent bin.
+ *
+ * After the EOS has been sent to the element, the application should wait for
+ * an EOS message to be posted on the pipeline's bus. Once this EOS message is
+ * received, it may safely shut down the entire pipeline.

+ *
+ * A seek updates the currently configured segment.start
+ * and segment.stop values based on the SEEK_TYPE. If the
+ * segment.start value is updated, a seek to this new position
+ * should be performed.
+ *
+ * The seek can only be executed when we are not currently
+ * streaming any data, to make sure that this is the case, we
+ * acquire the STREAM_LOCK which is taken when we are in the
+ * _loop() function or when a getrange() is called. Normally
+ * we will not receive a seek if we are operating in pull mode
+ * though. When we operate as a live source we might block on the live
+ * cond, which does not release the STREAM_LOCK. Therefore we will try
+ * to grab the LIVE_LOCK instead of the STREAM_LOCK to make sure it is
+ * safe to perform the seek.
+ *
+ * When we are in the loop() function, we might be in the middle
+ * of pushing a buffer, which might block in a sink. To make sure
+ * that the push gets unblocked we push out a FLUSH_START event.
+ * Our loop function will get a FLUSHING return value from
+ * the push and will pause, effectively releasing the STREAM_LOCK.
+ *
+ * For a non-flushing seek, we pause the task, which might eventually
+ * release the STREAM_LOCK. We say eventually because when the sink
+ * blocks on the sample we might wait a very long time until the sink
+ * unblocks the sample. In any case we acquire the STREAM_LOCK and
+ * can continue the seek. A non-flushing seek is normally done in a
+ * running pipeline to perform seamless playback, this means that the sink is
+ * PLAYING and will return from its chain function.
+ * In the case of a non-flushing seek we need to make sure that the
+ * data we output after the seek is continuous with the previous data,
+ * this is because a non-flushing seek does not reset the running-time
+ * to 0. We do this by closing the currently running segment, ie. sending
+ * a new_segment event with the stop position set to the last processed
+ * position.
+ *
+ * After updating the segment.start/stop values, we prepare for
+ * streaming again. We push out a FLUSH_STOP to make the peer pad
+ * accept data again and we start our task again.
+ *
+ * A segment seek posts a message on the bus saying that the playback
+ * of the segment started. We store the segment flag internally because
+ * when we reach the segment.stop we have to post a segment.done
+ * instead of EOS when doing a segment seek.

+/**
+ * SECTION:gstbasetransform
+ * @title: GstBaseTransform
+ * @short_description: Base class for simple transform filters
+ * @see_also: #GstBaseSrc, #GstBaseSink
+ *
+ * This base class is for filter elements that process data. Elements
+ * that are suitable for implementation using #GstBaseTransform are ones
+ * where the size and caps of the output is known entirely from the input
+ * caps and buffer sizes. These include elements that directly transform
+ * one buffer into another, modify the contents of a buffer in-place, as
+ * well as elements that collate multiple input buffers into one output buffer,
+ * or that expand one input buffer into multiple output buffers. See below
+ * for more concrete use cases.
+ *
+ * It provides for:
+ *
+ * * one sinkpad and one srcpad
+ * * Possible formats on sink and source pad implemented
+ *   with custom transform_caps function. By default uses
+ *   same format on sink and source.
+ *
+ * * Handles state changes
+ * * Does flushing
+ * * Push mode
+ * * Pull mode if the sub-class transform can operate on arbitrary data
+ *
+ * # Use Cases
+ *
+ * ## Passthrough mode
+ *
+ *   * Element has no interest in modifying the buffer. It may want to inspect it,
+ *     in which case the element should have a transform_ip function. If there
+ *     is no transform_ip function in passthrough mode, the buffer is pushed
+ *     intact.
+ *
+ *   * The #GstBaseTransformClass.passthrough_on_same_caps variable
+ *     will automatically set/unset passthrough based on whether the
+ *     element negotiates the same caps on both pads.
+ *
+ *   * #GstBaseTransformClass.passthrough_on_same_caps on an element that
+ *     doesn't implement a transform_caps function is useful for elements that
+ *     only inspect data (such as level)
+ *
+ *   * Example elements
+ *
+ *     * Level
+ *     * Videoscale, audioconvert, videoconvert, audioresample in certain modes.
+ *
+ * ## Modifications in-place - input buffer and output buffer are the same thing.
+ *
+ * * The element must implement a transform_ip function.
+ * * Output buffer size must <= input buffer size
+ * * If the always_in_place flag is set, non-writable buffers will be copied
+ *   and passed to the transform_ip function, otherwise a new buffer will be
+ *   created and the transform function called.
+ *
+ * * Incoming writable buffers will be passed to the transform_ip function
+ *   immediately.
+ * * only implementing transform_ip and not transform implies always_in_place = %TRUE
+ *
+ *   * Example elements:
+ *     * Volume
+ *     * Audioconvert in certain modes (signed/unsigned conversion)
+ *     * videoconvert in certain modes (endianness swapping)
+ *
+ * ## Modifications only to the caps/metadata of a buffer
+ *
+ * * The element does not require writable data, but non-writable buffers
+ *   should be subbuffered so that the meta-information can be replaced.
+ *
+ * * Elements wishing to operate in this mode should replace the
+ *   prepare_output_buffer method to create subbuffers of the input buffer
+ *   and set always_in_place to %TRUE
+ *
+ * * Example elements
+ *   * Capsfilter when setting caps on outgoing buffers that have
+ *     none.
+ *   * identity when it is going to re-timestamp buffers by
+ *     datarate.
+ *
+ * ## Normal mode
+ *   * always_in_place flag is not set, or there is no transform_ip function
+ *   * Element will receive an input buffer and output buffer to operate on.
+ *   * Output buffer is allocated by calling the prepare_output_buffer function.
+ *   * Example elements:
+ *     * Videoscale, videoconvert, audioconvert when doing
+ *     scaling/conversions
+ *
+ * ## Special output buffer allocations
+ *   * Elements which need to do special allocation of their output buffers
+ *     beyond allocating output buffers via the negotiated allocator or
+ *     buffer pool should implement the prepare_output_buffer method.
+ *
+ *   * Example elements:
+ *     * efence
+ *
+ * # Sub-class settable flags on GstBaseTransform
+ *
+ * * passthrough
+ *
+ *   * Implies that in the current configuration, the sub-class is not interested in modifying the buffers.
+ *   * Elements which are always in passthrough mode whenever the same caps has been negotiated on both pads can set the class variable passthrough_on_same_caps to have this behaviour automatically.
+ *
+ * * always_in_place
+ *   * Determines whether a non-writable buffer will be copied before passing
+ *     to the transform_ip function.
+ *
+ *   * Implied %TRUE if no transform function is implemented.
+ *   * Implied %FALSE if ONLY transform function is implemented.

+ *                           Set to %TRUE by default.
+ * @transform_caps: Optional.  Given the pad in this direction and the given

+ *                  element ?
+ * @fixate_caps:    Optional. Given the pad in this direction and the given
+ *                  caps, fixate the caps on the other pad. The function takes
+ *                  ownership of @othercaps and returns a fixated version of
+ *                  @othercaps. @othercaps is not guaranteed to be writable.
+ * @accept_caps:    Optional.
+ *                  Subclasses can override this method to check if @caps can be
+ *                  handled by the element. The default implementation might not be
+ *                  the most optimal way to check this in all cases.
+ * @set_caps:       allows the subclass to be notified of the actual caps set.
+ * @query:          Optional.
+ *                  Handle a requested query. Subclasses that implement this
+ *                  should must chain up to the parent if they didn't handle the
+ *                  query
+ * @decide_allocation: Setup the allocation parameters for allocating output
+ *                    buffers. The passed in query contains the result of the
+ *                    downstream allocation query. This function is only called
+ *                    when not operating in passthrough mode. The default
+ *                    implementation will remove all memory dependent metadata.
+ *                    If there is a @filter_meta method implementation, it will
+ *                    be called for all metadata API in the downstream query,
+ *                    otherwise the metadata API is removed.
+ * @filter_meta: Return %TRUE if the metadata API should be proposed in the
+ *               upstream allocation query. The default implementation is %NULL
+ *               and will cause all metadata to be removed.
+ * @propose_allocation: Propose buffer allocation parameters for upstream elements.
+ *                      This function must be implemented if the element reads or
+ *                      writes the buffer content. The query that was passed to
+ *                      the decide_allocation is passed in this method (or %NULL
+ *                      when the element is in passthrough mode). The default
+ *                      implementation will pass the query downstream when in
+ *                      passthrough mode and will copy all the filtered metadata
+ *                      API in non-passthrough mode.
+ * @transform_size: Optional. Given the size of a buffer in the given direction
+ *                  with the given caps, calculate the size in bytes of a buffer
+ *                  on the other pad with the given other caps.
+ *                  The default implementation uses get_unit_size and keeps
+ *                  the number of units the same.
+ * @get_unit_size:  Required if the transform is not in-place.
+ *                  get the size in bytes of one unit for the given caps.
+ * @start:          Optional.
+ *                  Called when the element starts processing.
+ *                  Allows opening external resources.
+ * @stop:           Optional.
+ *                  Called when the element stops processing.
+ *                  Allows closing external resources.
+ * @sink_event:     Optional.
+ *                  Event handler on the sink pad. The default implementation
+ *                  handles the event and forwards it downstream.
+ * @src_event:      Optional.
+ *                  Event handler on the source pad. The default implementation
+ *                  handles the event and forwards it upstream.
+ * @prepare_output_buffer: Optional.
+ *                         Subclasses can override this to do their own
+ *                         allocation of output buffers.  Elements that only do
+ *                         analysis can return a subbuffer or even just
+ *                         return a reference to the input buffer (if in
+ *                         passthrough mode). The default implementation will
+ *                         use the negotiated allocator or bufferpool and
+ *                         transform_size to allocate an output buffer or it
+ *                         will return the input buffer in passthrough mode.
+ * @copy_metadata: Optional.
+ *                 Copy the metadata from the input buffer to the output buffer.
+ *                 The default implementation will copy the flags, timestamps and
+ *                 offsets of the buffer.
+ * @transform_meta: Optional. Transform the metadata on the input buffer to the
+ *                  output buffer. By default this method copies all meta without
+ *                  tags. subclasses can implement this method and return %TRUE if
+ *                  the metadata is to be copied.
+ * @before_transform: Optional.
+ *                    This method is called right before the base class will
+ *                    start processing. Dynamic properties or other delayed
+ *                    configuration could be performed in this method.
+ * @transform:      Required if the element does not operate in-place.
+ *                  Transforms one incoming buffer to one outgoing buffer.
+ *                  The function is allowed to change size/timestamp/duration
+ *                  of the outgoing buffer.
+ * @transform_ip:   Required if the element operates in-place.
+ *                  Transform the incoming buffer in-place.
+ * @submit_input_buffer: Function which accepts a new input buffer and pre-processes it.
+ *                  The default implementation performs caps (re)negotiation, then
+ *                  QoS if needed, and places the input buffer into the @queued_buf
+ *                  member variable. If the buffer is dropped due to QoS, it returns
+ *                  GST_BASE_TRANSFORM_FLOW_DROPPED. If this input buffer is not
+ *                  contiguous with any previous input buffer, then @is_discont
+ *                  is set to %TRUE. (Since 1.6)
+ * @generate_output: Called after each new input buffer is submitted repeatedly
+ *                   until it either generates an error or fails to generate an output
+ *                   buffer. The default implementation takes the contents of the
+ *                   @queued_buf variable, generates an output buffer if needed
+ *                   by calling the class @prepare_output_buffer, and then
+ *                   calls either @transform or @transform_ip. Elements that don't
+ *                   do 1-to-1 transformations on input to output buffers can either
+ *                   return GST_BASE_TRANSFORM_FLOW_DROPPED or simply not generate
+ *                   an output buffer until they are ready to do so. (Since 1.6)
+ *
+ * Subclasses can override any of the available virtual methods or not, as
+ * needed. At minimum either @transform or @transform_ip need to be overridden.
+ * If the element can overwrite the input data with the results (data is of the
+ * same type and quantity) it should provide @transform_ip.

+/**
+ * SECTION:gstcollectpads
+ * @title: GstCollectPads
+ * @short_description: manages a set of pads that operate in collect mode
+ * @see_also:
+ *
+ * Manages a set of pads that operate in collect mode. This means that control
+ * is given to the manager of this object when all pads have data.
+ *
+ *   * Collectpads are created with gst_collect_pads_new(). A callback should then
+ *     be installed with gst_collect_pads_set_function ().
+ *
+ *   * Pads are added to the collection with gst_collect_pads_add_pad()/
+ *     gst_collect_pads_remove_pad(). The pad has to be a sinkpad. When added,
+ *     the chain, event and query functions of the pad are overridden. The
+ *     element_private of the pad is used to store private information for the
+ *     collectpads.
+ *
+ *   * For each pad, data is queued in the _chain function or by
+ *     performing a pull_range.
+ *
+ *   * When data is queued on all pads in waiting mode, the callback function is called.
+ *
+ *   * Data can be dequeued from the pad with the gst_collect_pads_pop() method.
+ *     One can peek at the data with the gst_collect_pads_peek() function.
+ *     These functions will return %NULL if the pad received an EOS event. When all
+ *     pads return %NULL from a gst_collect_pads_peek(), the element can emit an EOS
+ *     event itself.
+ *
+ *   * Data can also be dequeued in byte units using the gst_collect_pads_available(),
+ *     gst_collect_pads_read_buffer() and gst_collect_pads_flush() calls.
+ *
+ *   * Elements should call gst_collect_pads_start() and gst_collect_pads_stop() in
+ *     their state change functions to start and stop the processing of the collectpads.
+ *     The gst_collect_pads_stop() call should be called before calling the parent
+ *     element state change function in the PAUSED_TO_READY state change to ensure
+ *     no pad is blocked and the element can finish streaming.
+ *
+ *   * gst_collect_pads_set_waiting() sets a pad to waiting or non-waiting mode.
+ *     CollectPads element is not waiting for data to be collected on non-waiting pads.
+ *     Thus these pads may but need not have data when the callback is called.
+ *     All pads are in waiting mode by default.

+/**
+ * SECTION:gstflowcombiner
+ * @title: GstFlowCombiner
+ * @short_description: Utility to combine multiple flow returns into one
+ *
+ * Utility struct to help handling #GstFlowReturn combination. Useful for
+ * #GstElements that have multiple source pads and need to combine
+ * the different #GstFlowReturn for those pads.
+ *
+ * #GstFlowCombiner works by using the last #GstFlowReturn for all #GstPad
+ * it has in its list and computes the combined return value and provides
+ * it to the caller.
+ *
+ * To add a new pad to the #GstFlowCombiner use gst_flow_combiner_add_pad().
+ * The new #GstPad is stored with a default value of %GST_FLOW_OK.
+ *
+ * In case you want a #GstPad to be removed, use gst_flow_combiner_remove_pad().
+ *
+ * Please be aware that this struct isn't thread safe as its designed to be
+ *  used by demuxers, those usually will have a single thread operating it.
+ *
+ * These functions will take refs on the passed #GstPads.
+ *
+ * Aside from reducing the user's code size, the main advantage of using this
+ * helper struct is to follow the standard rules for #GstFlowReturn combination.
+ * These rules are:
+ *
+ * * %GST_FLOW_EOS: only if all returns are EOS too
+ * * %GST_FLOW_NOT_LINKED: only if all returns are NOT_LINKED too
+ * * %GST_FLOW_ERROR or below: if at least one returns an error return
+ * * %GST_FLOW_NOT_NEGOTIATED: if at least one returns a not-negotiated return
+ * * %GST_FLOW_FLUSHING: if at least one returns flushing
+ * * %GST_FLOW_OK: otherwise
+ *
+ * %GST_FLOW_ERROR or below, GST_FLOW_NOT_NEGOTIATED and GST_FLOW_FLUSHING are
+ * returned immediatelly from the gst_flow_combiner_update_flow() function.
+ *
+ * Since: 1.4

+ *
+ * #GstIndex is used to generate a stream index of one or more elements
+ * in a pipeline.
+ *
+ * Elements will overload the set_index and get_index virtual methods in
+ * #GstElement. When streaming data, the element will add index entries if it
+ * has an index set.
+ *
+ * Each element that adds to the index will do that using a writer_id. The
+ * writer_id is obtained from gst_index_get_writer_id().
+ *
+ * The application that wants to index the stream will create a new index object
+ * using gst_index_new() or gst_index_factory_make(). The index is assigned to a
+ * specific element, a bin or the whole pipeline. This will cause indexable
+ * elements to add entires to the index while playing.

+ * - no one seems to use GstIndexGroup, GstIndexCertainty
+ *
+ * - the API for application to use the index is mostly missing
+ *   - apps need to get a list of writers
+ *   - apps need to be able to iterate over each writers index entry collection
+ * - gst_index_get_assoc_entry() should pass ownership
+ *   - the GstIndexEntry structure is large and contains repetitive information
+ *   - we want to allow Indexers to implement a saner storage and create
+ *     GstIndexEntries on demand (the app has to free them), might even make

+ *
+ * This class is mostly useful for elements that cannot do
+ * random access, or at least very slowly. The source usually
+ * prefers to push out a fixed size buffer.
+ *
+ * Subclasses usually operate in a format that is different from the
+ * default GST_FORMAT_BYTES format of #GstBaseSrc.
+ *
+ * Classes extending this base class will usually be scheduled
+ * in a push based mode. If the peer accepts to operate without
+ * offsets and within the limits of the allowed block size, this
+ * class can operate in getrange based mode automatically. To make
+ * this possible, the subclass should implement and override the
+ * SCHEDULING query.
+ *
+ * The subclass should extend the methods from the baseclass in
+ * addition to the ::create method.
+ *
+ * Seeking, flushing, scheduling and sync is all handled by this
+ * base class.

+/**
+ * SECTION:gstharness
+ * @title: GstHarness
+ * @short_description: A test-harness for writing GStreamer unit tests
+ * @see_also: #GstTestClock
+ *
+ * #GstHarness is meant to make writing unit test for GStreamer much easier.
+ * It can be thought of as a way of treating a #GstElement as a black box,
+ * deterministically feeding it data, and controlling what data it outputs.
+ *
+ * The basic structure of #GstHarness is two "floating" #GstPads that connect
+ * to the harnessed #GstElement src and sink #GstPads like so:
+ *
+ * |[
+ *           __________________________
+ *  _____   |  _____            _____  |   _____
+ * |     |  | |     |          |     | |  |     |
+ * | src |--+-| sink|  Element | src |-+--| sink|
+ * |_____|  | |_____|          |_____| |  |_____|
+ *          |__________________________|
+ *
+ * ]|
+ *
+ * With this, you can now simulate any environment the #GstElement might find
+ * itself in. By specifying the #GstCaps of the harness #GstPads, using
+ * functions like gst_harness_set_src_caps() or gst_harness_set_sink_caps_str(),
+ * you can test how the #GstElement interacts with different caps sets.
+ *
+ * Your harnessed #GstElement can of course also be a bin, and using
+ * gst_harness_new_parse() supporting standard gst-launch syntax, you can
+ * easily test a whole pipeline instead of just one element.
+ *
+ * You can then go on to push #GstBuffers and #GstEvents on to the srcpad,
+ * using functions like gst_harness_push() and gst_harness_push_event(), and
+ * then pull them out to examine them with gst_harness_pull() and
+ * gst_harness_pull_event().
+ *
+ * ## A simple buffer-in buffer-out example
+ *
+ * |[
+ *   #include 
+ *   #include 
+ *   GstHarness *h;
+ *   GstBuffer *in_buf;
+ *   GstBuffer *out_buf;
+ *
+ *   // attach the harness to the src and sink pad of GstQueue
+ *   h = gst_harness_new ("queue");
+ *
+ *   // we must specify a caps before pushing buffers
+ *   gst_harness_set_src_caps_str (h, "mycaps");
+ *
+ *   // create a buffer of size 42
+ *   in_buf = gst_harness_create_buffer (h, 42);
+ *
+ *   // push the buffer into the queue
+ *   gst_harness_push (h, in_buf);

+ * Another main feature of the #GstHarness is its integration with the
+ * #GstTestClock. Operating the #GstTestClock can be very challenging, but
+ * #GstHarness simplifies some of the most desired actions a lot, like wanting
+ * to manually advance the clock while at the same time releasing a #GstClockID
+ * that is waiting, with functions like gst_harness_crank_single_clock_wait().
+ *
+ * #GstHarness also supports sub-harnesses, as a way of generating and
+ * validating data. A sub-harness is another #GstHarness that is managed by
+ * the "parent" harness, and can either be created by using the standard
+ * gst_harness_new type functions directly on the (GstHarness *)->src_harness,
+ * or using the much more convenient gst_harness_add_src() or
+ * gst_harness_add_sink_parse(). If you have a decoder-element you want to test,
+ * (like vp8dec) it can be very useful to add a src-harness with both a
+ * src-element (videotestsrc) and an encoder (vp8enc) to feed the decoder data
+ * with different configurations, by simply doing:
+ *
+ * |[
+ *   GstHarness * h = gst_harness_new (h, "vp8dec");
+ *   gst_harness_add_src_parse (h, "videotestsrc is-live=1 ! vp8enc", TRUE);
+ * ]|
+ *
+ * and then feeding it data with:
+ *
+ * |[
+ * gst_harness_push_from_src (h);
+ * ]|

+ * @see_also: #GstSystemClock, #GstClock
+ *
+ * GstTestClock is an implementation of #GstClock which has different
+ * behaviour compared to #GstSystemClock. Time for #GstSystemClock advances
+ * according to the system time, while time for #GstTestClock changes only
+ * when gst_test_clock_set_time() or gst_test_clock_advance_time() are
+ * called. #GstTestClock provides unit tests with the possibility to
+ * precisely advance the time in a deterministic manner, independent of the
+ * system time or any other external factors.

+ * #GstClock allows for setting up single shot or periodic clock notifications
+ * as well as waiting for these notifications synchronously (using
+ * gst_clock_id_wait()) or asynchronously (using gst_clock_id_wait_async() or
+ * gst_clock_id_wait_async()). This is used by many GStreamer elements,
+ * among them #GstBaseSrc and #GstBaseSink.
+ *
+ * #GstTestClock keeps track of these clock notifications. By calling
+ * gst_test_clock_wait_for_next_pending_id() or
+ * gst_test_clock_wait_for_multiple_pending_ids() a unit tests may wait for the
+ * next one or several clock notifications to be requested. Additionally unit
+ * tests may release blocked waits in a controlled fashion by calling
+ * gst_test_clock_process_next_clock_id(). This way a unit test can control the
+ * inaccuracy (jitter) of clock notifications, since the test can decide to
+ * release blocked waits when the clock time has advanced exactly to, or past,
+ * the requested clock notification time.
+ *
+ * There are also interfaces for determining if a notification belongs to a
+ * #GstTestClock or not, as well as getting the number of requested clock
+ * notifications so far.
+ *
+ * N.B.: When a unit test waits for a certain amount of clock notifications to
+ * be requested in gst_test_clock_wait_for_next_pending_id() or
+ * gst_test_clock_wait_for_multiple_pending_ids() then these functions may block
+ * for a long time. If they block forever then the expected clock notifications
+ * were never requested from #GstTestClock, and so the assumptions in the code
+ * of the unit test are wrong. The unit test case runner in gstcheck is
+ * expected to catch these cases either by the default test case timeout or the
+ * one set for the unit test by calling tcase_set_timeout\(\).
+ *
+ * The sample code below assumes that the element under test will delay a
+ * buffer pushed on the source pad by some latency until it arrives on the sink
+ * pad. Moreover it is assumed that the element will at some point call
+ * gst_clock_id_wait() to synchronously wait for a specific time. The first
+ * buffer sent will arrive exactly on time only delayed by the latency. The
+ * second buffer will arrive a little late (7ms) due to simulated jitter in the
+ * clock notification.

+ * - Before reading, the parent rewind()'s the file to reset both
+ *   FILE* and underlying file descriptor location data.
+ * - When finished, the parent fclose()'s the FILE*, deleting the
+ *   temporary file, per tmpfile()'s semantics.

+ * SECTION:gstnetclientclock
+ * @title: GstNetClientClock
+ * @short_description: Special clock that synchronizes to a remote time
+ *                     provider.
+ * @see_also: #GstClock, #GstNetTimeProvider, #GstPipeline
+ *
+ * #GstNetClientClock implements a custom #GstClock that synchronizes its time
+ * to a remote time provider such as #GstNetTimeProvider. #GstNtpClock
+ * implements a #GstClock that synchronizes its time to a remote NTPv4 server.
+ *
+ * A new clock is created with gst_net_client_clock_new() or
+ * gst_ntp_clock_new(), which takes the address and port of the remote time
+ * provider along with a name and an initial time.
+ *
+ * This clock will poll the time provider and will update its calibration
+ * parameters based on the local and remote observations.
+ *
+ * The "round-trip" property limits the maximum round trip packets can take.
+ *
+ * Various parameters of the clock can be configured with the parent #GstClock
+ * "timeout", "window-size" and "window-threshold" object properties.
+ *
+ * A #GstNetClientClock and #GstNtpClock is typically set on a #GstPipeline with
+ * gst_pipeline_use_clock().
+ *
+ * If you set a #GstBus on the clock via the "bus" object property, it will
+ * send @GST_MESSAGE_ELEMENT messages with an attached #GstStructure containing
+ * statistics about clock accuracy and network traffic.

+ *                     on the network.
+ * @see_also: #GstClock, #GstNetClientClock, #GstPipeline
+ *
+ * This object exposes the time of a #GstClock on the network.
+ *
+ * A #GstNetTimeProvider is created with gst_net_time_provider_new() which
+ * takes a #GstClock, an address and a port number as arguments.
+ *
+ * After creating the object, a client clock such as #GstNetClientClock can
+ * query the exposed clock over the network for its values.
+ *
+ * The #GstNetTimeProvider typically wraps the clock used by a #GstPipeline.

+ * synchronize to all PTP domains that are detected on the selected

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# warranty; '.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##

+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.

+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to
+# quote other shell meta-characters carefully to prevent them being
+# expanded when the contents are evaled.

+# override it after sourcing this library to reflect the full set of

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl    default (if it is not specified or empty) is 'no-libtool'.
+dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl    depending on --{enable,disable}-{shared,static} and on the presence of
+dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function
+dnl    will be ignored.  If NEEDSYMBOL is specified and is
+dnl    'need-formatstring-macros', then GNU gettext implementations that don't
+dnl    support the ISO C 99  formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries.  If empty,
+dnl    the value `$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl    and used.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl    Catalog format: none
+dnl    Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+# serial 5 lt~obsolete.m4
+
+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

+ * Concatenates streams together to one continous stream.
+ *
+ * All streams but the current one are blocked until the current one
+ * finished with %GST_EVENT_EOS. Then the next stream is enabled, while
+ * keeping the running time continous for %GST_FORMAT_TIME segments or
+ * keeping the segment continous for %GST_FORMAT_BYTES segments.
+ *
+ * Streams are switched in the order in which the sinkpads were requested.
+ *
+ * By default, the stream segment's base values are adjusted to ensure
+ * the segment transitions between streams are continuous. In some cases,
+ * it may be desirable to turn off these adjustments (for example, because
+ * another downstream element like a streamsynchronizer adjusts the base
+ * values on its own). The adjust-base property can be used for this purpose.

+/**
+ * SECTION:element-downloadbuffer
+ * @title: downloadbuffer
+ *
+ * The downloadbuffer element provides on-disk buffering and caching of, typically,
+ * a network file. temp-template should be set to a value such as
+ * /tmp/gstreamer-XXXXXX and the element will allocate a random free filename and
+ * buffer the data in the file.
+ *
+ * With max-size-bytes and max-size-time you can configure the buffering limits.
+ * The downloadbuffer element will try to read-ahead these amounts of data. When
+ * the amount of read-ahead data drops below low-percent of the configured max,
+ * the element will start emitting BUFFERING messages until high-percent of max is
+ * reached again.
+ *
+ * The downloadbuffer provides push and pull based scheduling on its source pad
+ * and will efficiently seek in the upstream element when needed.
+ *
+ * The temp-location property will be used to notify the application of the
+ * allocated filename.
+ *
+ * When the downloadbuffer has completely downloaded the media, it will
+ * post an application message named  "GstCacheDownloadComplete"
+ * with the following information:
+ *
+ * *
+ *   G_TYPE_STRING
+ *   "location":
+ *   the location of the completely downloaded file.

+/**
+ * SECTION:element-multiqueue
+ * @title: multiqueue
+ * @see_also: #GstQueue
+ *
+ * Multiqueue is similar to a normal #GstQueue with the following additional
+ * features:
+ *
+ * 1) Multiple streamhandling
+ *
+ *  * The element handles queueing data on more than one stream at once. To
+ * achieve such a feature it has request sink pads (sink%u) and
+ * 'sometimes' src pads (src%u). When requesting a given sinkpad with gst_element_request_pad(),
+ * the associated srcpad for that stream will be created.
+ * Example: requesting sink1 will generate src1.
+ *
+ * 2) Non-starvation on multiple stream
+ *
+ * * If more than one stream is used with the element, the streams' queues
+ * will be dynamically grown (up to a limit), in order to ensure that no
+ * stream is risking data starvation. This guarantees that at any given
+ * time there are at least N bytes queued and available for each individual
+ * stream. If an EOS event comes through a srcpad, the associated queue will be
+ * considered as 'not-empty' in the queue-size-growing algorithm.
+ *
+ * 3) Non-linked srcpads graceful handling
+ *
+ * * In order to better support dynamic switching between streams, the multiqueue
+ * (unlike the current GStreamer queue) continues to push buffers on non-linked
+ * pads rather than shutting down. In addition, to prevent a non-linked stream from very quickly consuming all
+ * available buffers and thus 'racing ahead' of the other streams, the element
+ * must ensure that buffers and inlined events for a non-linked stream are pushed
+ * in the same order as they were received, relative to the other streams
+ * controlled by the element. This means that a buffer cannot be pushed to a
+ * non-linked pad any sooner than buffers in any other stream which were received
+ * before it.
+ *
+ * Data is queued until one of the limits specified by the
+ * #GstMultiQueue:max-size-buffers, #GstMultiQueue:max-size-bytes and/or
+ * #GstMultiQueue:max-size-time properties has been reached. Any attempt to push
+ * more buffers into the queue will block the pushing thread until more space
+ * becomes available. #GstMultiQueue:extra-size-buffers,
+ *
+ *
+ * #GstMultiQueue:extra-size-bytes and #GstMultiQueue:extra-size-time are
+ * currently unused.
+ *
+ * The default queue size limits are 5 buffers, 10MB of data, or
+ * two second worth of data, whichever is reached first. Note that the number
+ * of buffers will dynamically grow depending on the fill level of
+ * other queues.
+ *
+ * The #GstMultiQueue::underrun signal is emitted when all of the queues
+ * are empty. The #GstMultiQueue::overrun signal is emitted when one of the
+ * queues is filled.
+ * Both signals are emitted from the context of the streaming thread.
+ *
+ * When using #GstMultiQueue:sync-by-running-time the unlinked streams will
+ * be throttled by the highest running-time of linked streams. This allows
+ * further relinking of those unlinked streams without them being in the
+ * future (i.e. to achieve gapless playback).
+ * When dealing with streams which have got different consumption requirements
+ * downstream (ex: video decoders which will consume more buffer (in time) than
+ * audio decoders), it is recommended to group streams of the same type
+ * by using the pad "group-id" property. This will further throttle streams
+ * in time within that group.

+ * The buffering_level functions here return a value in a normalized range
+ * that specifies the current fill level of a queue. The range goes from 0 to
+ * MAX_BUFFERING_LEVEL. The low/high watermarks also use this same range.
+ *
+ * This is not to be confused with the buffering_percent value, which is
+ * a *relative* quantity - relative to the low/high watermarks.
+ * buffering_percent = 0% means overall buffering_level is at the low watermark.
+ * buffering_percent = 100% means overall buffering_level is at the high watermark.
+ * buffering_percent is used for determining if the fill level has reached
+ * the high watermark, and for producing BUFFERING messages. This value
+ * always uses a 0..100 range (since it is a percentage).
+ *
+ * To avoid future confusions, whenever "buffering level" is mentioned, it
+ * refers to the absolute level which is in the 0..MAX_BUFFERING_LEVEL
+ * range. Whenever "buffering_percent" is mentioned, it refers to the
+ * percentage value that is relative to the low/high watermark. */

+/**
+ * SECTION:element-queue
+ * @title: queue
+ *
+ * Data is queued until one of the limits specified by the
+ * #GstQueue:max-size-buffers, #GstQueue:max-size-bytes and/or
+ * #GstQueue:max-size-time properties has been reached. Any attempt to push
+ * more buffers into the queue will block the pushing thread until more space
+ * becomes available.
+ *
+ * The queue will create a new thread on the source pad to decouple the
+ * processing on sink and source pad.
+ *
+ * You can query how many buffers are queued by reading the
+ * #GstQueue:current-level-buffers property. You can track changes
+ * by connecting to the notify::current-level-buffers signal (which
+ * like all signals will be emitted from the streaming thread). The same
+ * applies to the #GstQueue:current-level-time and
+ * #GstQueue:current-level-bytes properties.
+ *
+ * The default queue size limits are 200 buffers, 10MB of data, or
+ * one second worth of data, whichever is reached first.
+ *
+ * As said earlier, the queue blocks by default when one of the specified
+ * maximums (bytes, time, buffers) has been reached. You can set the
+ * #GstQueue:leaky property to specify that instead of blocking it should
+ * leak (drop) new or old buffers.
+ *
+ * The #GstQueue::underrun signal is emitted when the queue has less data than
+ * the specified minimum thresholds require (by default: when the queue is
+ * empty). The #GstQueue::overrun signal is emitted when the queue is filled
+ * up. Both signals are emitted from the context of the streaming thread.

+ *
+ * The default queue size limits are 100 buffers, 2MB of data, or
+ * two seconds worth of data, whichever is reached first.
+ *
+ * If you set temp-template to a value such as /tmp/gstreamer-XXXXXX, the element
+ * will allocate a random free filename and buffer data in the file.
+ * By using this, it will buffer the entire stream data on the file independently
+ * of the queue size limits, they will only be used for buffering statistics.
+ *
+ * The temp-location property will be used to notify the application of the

+ * buffering_percent = 0% means buffering_level is at the low watermark.

+ * buffering_percent is used for determining if the fill level has reached
+ * the high watermark, and for producing BUFFERING messages. This value
+ * always uses a 0..100 range (since it is a percentage).
+ *
+ * To avoid future confusions, whenever "buffering level" is mentioned, it

+ *
+ * The basic concept was started from de-funneling element which restores one
+ * serialized stream via #GstFunnel to its original state. #GstStreamidDemux
+ * classifies each stream base on stream ids.
+ *
+ * The stream id demux always takes one input and checks how many streams
+ * are contained in a stream by STREAM_START event. Likewise #GstFunnel,
+ * #GstStreamidDemux does not synchronize the different output streams.
+ *
+ * #GstStreamidDemux:active-pad provides information about which output pad
+ * is activated at the moment.

+ * @see_also: #GstFunnel, #gst_event_new_stream_start

+ * Split data to multiple pads. Branching the data flow is useful when e.g.
+ * capturing a video where the video is shown on the screen and also encoded and
+ * written to a file. Another example is playing music and hooking up a
+ * visualisation module.
+ *
+ * One needs to use separate queue elements (or a multiqueue) in each branch to
+ * provide separate threads for each branch. Otherwise a blocked dataflow in one
+ * branch would stall the other branches.
+ *
+ * ## Example launch line
+ * |[
+ * gst-launch-1.0 filesrc location=song.ogg ! decodebin ! tee name=t ! queue ! audioconvert ! audioresample ! autoaudiosink t. ! queue ! audioconvert ! goom ! videoconvert ! autovideosink
+ * ]|
+ *
+ * Play song.ogg audio file which must be in the current working directory
+ * and render visualisations using the goom element (this can be easier done
+ * using the playbin element, this is just an example pipeline).

+/**
+ * SECTION:element-typefind
+ * @title: typefind
+ *
+ * Determines the media-type of a stream. It applies typefind functions in the
+ * order of their rank. Once the type has been detected it sets its src pad caps
+ * to the found media type.
+ *
+ * Whenever a type is found the #GstTypeFindElement::have-type signal is
+ * emitted, either from the streaming thread or the application thread
+ * (the latter may happen when typefinding is done pull-based from the
+ * state change function).
+ *
+ * Plugins can register custom typefinders by using #GstTypeFindFactory.
+ */
+
+/* FIXME: need a better solution for non-seekable streams */
+
+/* way of operation:
+ * 1) get a list of all typefind functions sorted best to worst
+ * 2) if all elements have been called with all requested data goto 8
+ * 3) call all functions once with all available data
+ * 4) if a function returns a value >= PROP_MAXIMUM goto 8 (never implemented))
+ * 5) all functions with a result > PROP_MINIMUM or functions that did not get
+ *    all requested data (where peek returned NULL) stay in list
+ * 6) seek to requested offset of best function that still has open data
+ *    requests
+ * 7) goto 2
+ * 8) take best available result and use its caps
+ *
+ * The element has two scheduling modes:
+ *
+ * 1) chain based, it will collect buffers and run the typefind function on
+ *    the buffer until something is found.
+ * 2) getrange based, it will proxy the getrange function to the sinkpad. It
+ *    is assumed that the peer element is happy with whatever format we
+ *    eventually read.
+ *
+ * By default it tries to do pull based typefinding (this avoids joining
+ * received buffers and holding them back in store.)
+ *
+ * When the element has no connected srcpad, and the sinkpad can operate in
+ * getrange based mode, the element starts its own task to figure out the
+ * type of the stream.
+ *
+ * Most of the actual implementation is in libs/gst/base/gsttypefindhelper.c.

+# Alcune note (essenzialmente una traduzione) dopo una lettura non troppo
+# approfondita del manuale di GStreamer
+#
+# Tenete presente che, da un punto di vista dello sviluppatore, GStreamer
+# è pesantemente influenzato dalla struttura di GLib, ed in particolare
+# dei GObject, per cui le varie funzioni di libreria operano con il
+# criterio della programmazione orientata agli oggetti.
+#
+# Per chi mi capisce, e tagliando via elementi qui non essenziali
+#
+# GObject
+#         GstObject
+#                 GstPad
+#                 GstElement
+#                         GstBin
+#                                 GstPipeline
+#                                 GstThread
+#
+#
+# --- Elements ---
+#
+# Un elemento è il blocco costruttivo di base per una "media pipeline".
+# Tutti i differenti elementi di alto livello usati sono derivati da
+# GstElement. Gli elementi sono "black boxes" con un numero di differenti
+# aspetti. Uno di questi aspetti è la presenza di "pads", o punti di
+# collegamento (link points). This terminology arises from soldering; pads
+# are where wires can be attached.
+#
+# Tipi di elemento:
+#       * source - genera i dati da usare in una pipeline, ad es. leggendo
+#         da qualcosa (disco, rete, canale scheda audio...). Hanno solo un
+#         source pad
+#       * filter/codec - hanno dei pad di input ed output. Operano sui
+#         dati che ricevono nel sink pad e producono dati sul loro source
+#         pad. Un demuxer appartiene a questa categoria (1 in, 2 out)
+#       * sink - punto d'uscita di una pipeline, accettano dati senza
+#         produrne altri. Implementazioni di elementi sink sono la
+#         scrittura su file, la riproduzione audio o video.
+#
+# --- Pads ---
+#
+# Sono l'interfaccia di un elemento verso il mondo esterno. Permettono di
+# esporre il tipo specifico di media che l'elemento può gestire.
+#
+# I pad possono essere source e sink: ciò dipende dal punto di vista
+# dell'elemento cui appartengono
+#
+# Tipi di pad:
+#       * dinamici - l'elemento crea un pad se necessario, esempio: mpeg
+#         multiplexer crea pad a seconda dei differenti stream elementari
+#         rilevati nello stream mpeg
+#       * requested - pad creato on demand
+#
+# --- Capabilities ---
+#
+# Usate per descrivere i tipi di dati che possono "attraversare" il pad.
+# Sono allegate al pad stesso. Capabilities sta per "capability chain"
+#
+# [Salto le parti complicate] Le capabilities sono usate per
+# l'autoplugging (automatically finding plugins for a set of capabilities)
+# ed il rilevamento di compatibilità (tra due pad collegati - "caps
+# negotiation")
+#
+# --- Link ---
+#
+# Dati tre elementi (source, filter, sink) posso collegare in modo
+# opportuno i relativi pad, creando una catena. Vedi allegato.
+#
+# --- Bins ---
+#
+# Un bin è un elemento contenitore. È possibile aggiungere elementi ad un
+# bin, così come è possibile aggiungerlo ad un altro bin.
+#
+# Consente di combinare un gruppo di elementi collegati in un elemento
+# logico. A questo punto non serve + ragionare in termini dei singoli
+# elementi, ma del bin.
+#
+# Una pipeline è un elemento bin, un contenitore generico che consente la
+# schedulazione degli elementi contenuti. Il "toplevel bin" deve essere
+# una pipeline.
+#
+# Anche un thread è un elemento bin, che consente l'esecuzione separata.
+#
+# --- Buffers ---
+#
+# Contengono i dati che scorrono (flow) attraverso una pipeline.
+# Tipicamente gli elementi source creano un nuovo buffer.
+#
+# --- Element states ---
+#
+#       * NULL - predefinito, l'elemento è creato e non sta facendo
+#         alcunché
+#       * READY - pronto a fare qualcosa
+#       * PAUSED - in pausa
+#       * PLAYING - sta facendo qualcosa
+#
+# Si passa da NULL a PLAYING attraverso i due stati intermedi.

+# Sinks are special elements in GStreamer. This is because sink elements have to take care of preroll, which is the process that takes care that elements going into the GST_STATE_PAUSED state will have buffers ready after the state change. The result of this is that such elements can start processing data immediately after going into the GST_STATE_PLAYING state, without requiring to take some time to initialize outputs or set up decoders; all that is done already before the state-change to GST_STATE_PAUSED  successfully completes.
+#
+# Preroll, however, is a complex process that would require the same code in many elements. Therefore, sink elements can derive from the GstBaseSink base-class, which does preroll and a few other utility functions automatically. The derived class only needs to implement a bunch of virtual functions and will work automatically.

+;;; Commentary:
+;;
+;; Network clock simulator.
+;;
+;; Simulates the attempts of one clock to synchronize with another over
+;; the network. Packets are sent out with a local timestamp, and come
+;; back with the remote time added on to the packet. The remote time is
+;; assumed to have been observed at the local time in between sending
+;; the query and receiving the reply.
+;;
+;; The local clock will attempt to adjust its rate and offset by fitting
+;; a line to the last N datapoints on hand, by default 32. A better fit,
+;; as measured by the correlation coefficient, will result in a longer
+;; time before the next query. Bad fits or a not-yet-full set of data
+;; will result in many queries in quick succession.
+;;
+;; The rate and offset are set directly to the slope and intercept from
+;; the linear regression. This results in discontinuities in the local
+;; time. As clock times must be monotonically increasing, a jump down in
+;; time will result instead in time standing still for a while. Smoothly
+;; varying the rate such that no discontinuities are present has not
+;; been investigated.
+;;
+;; Implementation-wise, this simulator processes events and calculates
+;; times discretely. Times are represented as streams, also known as
+;; lazy lists. This is an almost-pure functional simulator. The thing to
+;; remember while reading is that stream-cons does not evaluate its
+;; second argument, rather deferring that calculation until stream-cdr
+;; is called. In that way all times are actually infinite series.
+;;
+;; Usage: See network-clock.scm --help.

+.SH "NAME"
+gst\-inspect\-1.0 \- print info about a GStreamer plugin or element
+.SH "SYNOPSIS"
+.B  gst\-inspect\-1.0 [OPTION...] [PLUGIN|ELEMENT]
+.SH "DESCRIPTION"
+.PP
+\fIgst\-inspect\-1.0\fP is a tool that prints out information on
+available \fIGStreamer\fP plugins, information about a particular
+plugin, or information about a particular element.  When executed
+with no PLUGIN or ELEMENT argument, \fIgst\-inspect\-1.0\fP will print
+a list of all plugins and elements together with a summary.
+When executed with a PLUGIN or ELEMENT argument,
+\fIgst\-inspect\-1.0\fP will print information about that plug-in or
+element.
+.
+.SH "OPTIONS"
+.l
+\fIgst\-inspect\-1.0\fP accepts the following arguments and options:
+.TP 8
+.B  PLUGIN
+Name of a plugin
+.TP 8
+.B  ELEMENT
+Name of an element
+.TP 8
+.B  \-\-help
+Print help synopsis and available FLAGS
+.TP 8
+.B  \-\-gst\-info\-mask=FLAGS
+\fIGStreamer\fP info flags to set (list with \-\-help)
+.TP 8
+.B  \-a, \-\-print\-all
+Print all plugins and elements
+.TP 8
+.B  \-b, \-\-print\-blacklist
+Print list of blacklisted files
+.TP 8
+.B  \-\-plugin
+List the plugin contents
+.TP 8
+.B  \-\-types=Element/Types
+Allow inspecting only elements that match all the element types filtered
+in this slash (\'/\') separated list of element types. Those types correspond to
+what is also called \'klass\' which is a string describing the type of
+element, like \'Decoder\', \'Audio\', \'Encoder\' etc... This options
+implies that only elements will be printed (not typefind functions or
+tracers).
+.TP 8
+.B  \-\-exists
+Check if the specified element or plugin exists
+.TP 8
+.B  \-\-atleast\-version
+When checking if an element or plugin exists, also check that its version
+is at least the version specified
+.TP 8
+.B  \-u, \-\-uri\-handlers
+Print supported URI schemes, with the elements that implement them
+.TP 8
+.B  \-\-print\-plugin\-auto\-install\-info
+Print a machine-parsable list of features the specified plugin provides.
+Useful in connection with external automatic plugin installation mechanisms.
+.TP 8
+.B  \-\-gst\-debug\-mask=FLAGS
+\fIGStreamer\fP debugging flags to set (list with \-\-help)
+.TP 8
+.B  \-\-gst\-mask=FLAGS
+\fIGStreamer\fP info and debugging flags to set (list with \-\-help)
+.TP 8
+.B  \-\-gst\-plugin\-spew
+\fIGStreamer\fP info flags to set
+Enable printout of errors while loading \fIGStreamer\fP plugins
+.TP 8
+.B  \-\-gst\-plugin\-path=PATH
+Add directories separated with ':' to the plugin search path

+.TH "GStreamer" "1" "May 2007"
+.SH "NAME"
+gst\-launch\-1.0 \- build and run a GStreamer pipeline
+.SH "SYNOPSIS"
+\fBgst\-launch\-1.0\fR \fI[OPTION...]\fR PIPELINE\-DESCRIPTION
+.SH "DESCRIPTION"
+.LP
+\fIgst\-launch\-1.0\fP is a tool that builds and runs basic
+\fIGStreamer\fP pipelines.
+
+In simple form, a PIPELINE\-DESCRIPTION is a list of
+elements separated by exclamation marks (!). Properties may be appended to
+elements, in the form \fIproperty=value\fR.
+
+For a complete description of possible PIPELINE-DESCRIPTIONS see the section
+\fIpipeline description\fR below or consult the GStreamer documentation.
+
+Please note that \fIgst\-launch\-1.0\fP is primarily a debugging tool for
+developers and users. You should not build applications on top of it. For
+applications, use the gst_parse_launch() function of the GStreamer API as an
+easy way to construct pipelines from pipeline descriptions.
+.
+.SH "OPTIONS"
+.l
+\fIgst\-launch\-1.0\fP accepts the following options:
+.TP 8
+.B  \-\-help
+Print help synopsis and available FLAGS
+.TP 8
+.B  \-v, \-\-verbose
+Output status information and property notifications
+.TP 8
+.B  \-q, \-\-quiet
+Do not print any progress information
+.TP 8
+.B  \-m, \-\-messages
+Output messages posted on the pipeline's bus
+.TP 8
+.B  \-t, \-\-tags
+Output tags (also known as metadata)
+.TP 8
+.B  \-e, \-\-eos\-on\-shutdown
+Force an EOS event on sources before shutting the pipeline down. This is
+useful to make sure muxers create readable files when a muxing pipeline is
+shut down forcefully via Control-C.
+.TP 8
+.B  \-i, \-\-index
+Gather and print index statistics. This is mostly useful for playback or
+recording pipelines.
+.TP 8
+.B  \-f, \-\-no\-fault
+Do not install a fault handler
+.TP 8
+.B  \-T, \-\-trace
+Print memory allocation traces. The feature must be enabled at compile time to
+work.
+.TP 8
+
+.
+.SH "GSTREAMER OPTIONS"
+.l
+\fIgst\-launch\-1.0\fP also accepts the following options that are common
+to all GStreamer applications:
+.TP 8
+.B  \-\-gst\-version
+Prints the version string of the \fIGStreamer\fP core library.
+.TP 8
+.B  \-\-gst\-fatal\-warnings
+Causes \fIGStreamer\fP to abort if a warning message occurs. This is equivalent
+to setting the environment variable G_DEBUG to 'fatal_warnings' (see the
+section \fIenvironment variables\fR below for further information).
+.TP 8
+.B  \-\-gst\-debug=STRING
+A comma separated list of category_name:level pairs to specify debugging levels
+for each category. Level is in the range 0-9 where 0 will show no messages, and
+9 will show all messages. The wildcard * can be used to match category names.
+Note that the order of categories and levels is important, wildcards at the
+end may override levels set earlier. The log levels are: 1=ERROR, 2=WARNING,
+3=FIXME, 4=INFO, 5=DEBUG, 6=LOG, 7=TRACE, 9=MEMDUMP. Since GStreamer 1.2 one
+can also use the debug level names, e.g. \-\-gst\-debug=*sink:LOG. A full
+description of the various debug levels can be found in the GStreamer core
+library API documentation, in the "Running GStreamer Applications" section.
+
+Use \-\-gst\-debug\-help to show category names
+
+Example:
+GST_CAT:5,GST_ELEMENT_*:3,oggdemux:5
+
+.TP 8
+.B  \-\-gst\-debug\-level=LEVEL
+Sets the threshold for printing debugging messages.  A higher level
+will print more messages.  The useful range is 0-9, with the default
+being 0. Level 6 (LOG level) will show all information that is usually
+required for debugging purposes. Higher levels are only useful in very
+specific cases. See above for the full list of levels.
+.TP 8
+.B  \-\-gst\-debug\-no\-color
+\fIGStreamer\fP normally prints debugging messages so that the
+messages are color-coded when printed to a terminal that handles
+ANSI escape sequences.  Using this option causes \fIGStreamer\fP
+to print messages without color. Setting the \fBGST_DEBUG_NO_COLOR\fR
+environment variable will achieve the same thing.
+.TP 8
+.B  \-\-gst\-debug\-color\-mode
+\fIGStreamer\fP normally prints debugging messages so that the
+messages are color-coded when printed to a terminal that handles
+ANSI escape sequences (on *nix), or uses W32 console API to color the
+messages printed into a console (on W32). Using this option causes
+\fIGStreamer\fP to print messages without color ('off' or 'disable'),
+print messages with default colors ('on' or 'auto'), or print messages
+using ANSI escape sequences for coloring ('unix'). Setting the
+\fBGST_DEBUG_COLOR_MODE\fR environment variable will achieve the same thing.
+.TP 8
+.B  \-\-gst\-debug\-disable
+Disables debugging.
+.TP 8
+.B  \-\-gst\-debug\-help
+Prints a list of available debug categories and their default debugging level.
+.TP 8
+.B  \-\-gst\-plugin\-spew
+\fIGStreamer\fP info flags to set
+Enable printout of errors while loading \fIGStreamer\fP plugins
+.TP 8
+.B  \-\-gst\-plugin\-path=PATH
+Add directories separated with ':' to the plugin search path
+.TP 8
+.B  \-\-gst\-plugin\-load=PLUGINS
+Preload plugins specified in a comma-separated list. Another way to specify
+plugins to preload is to use the environment variable GST_PLUGIN_PATH
+
+.SH "PIPELINE DESCRIPTION"
+
+A pipeline consists \fIelements\fR and \fIlinks\fR. \fIElements\fR can be put
+into \fIbins\fR of different sorts. \fIElements\fR, \fIlinks\fR and \fIbins\fR
+can be specified in a pipeline description in any order.
+
+.B Elements
+
+ELEMENTTYPE \fI[PROPERTY1 ...]\fR
+
+Creates an element of type ELEMENTTYPE and sets the PROPERTIES.
+
+.B Properties
+
+PROPERTY=VALUE ...
+
+Sets the property to the specified value. You can use \fBgst\-inspect\-1.0\fR(1) to
+find out about properties and allowed values of different elements.
+.br
+Enumeration properties can be set by name, nick or value.
+
+.B Bins
+
+\fI[BINTYPE.]\fR ( \fI[PROPERTY1 ...]\fR PIPELINE-DESCRIPTION )
+.br
+
+Specifies that a bin of type BINTYPE is created and the given properties are
+set. Every element between the braces is put into the bin. Please note the dot
+that has to be used after the BINTYPE. You will almost never need this
+functionality, it is only really useful for applications using the
+gst_launch_parse() API with 'bin' as bintype. That way it is possible to build
+partial pipelines instead of a full-fledged top-level pipeline.
+
+.B Links
+
+\fI[[SRCELEMENT].[PAD1,...]]\fR ! \fI[[SINKELEMENT].[PAD1,...]]\fR
+\fI[[SRCELEMENT].[PAD1,...]]\fR ! CAPS ! \fI[[SINKELEMENT].[PAD1,...]]\fR
+\fI[[SRCELEMENT].[PAD1,...]]\fR : \fI[[SINKELEMENT].[PAD1,...]]\fR
+\fI[[SRCELEMENT].[PAD1,...]]\fR : CAPS : \fI[[SINKELEMENT].[PAD1,...]]\fR
+
+Links the element with name SRCELEMENT to the element with name SINKELEMENT,
+using the caps specified in CAPS as a filter.
+Names can be set on elements with the name property. If the name is omitted, the
+element that was specified directly in front of or after the link is used. This
+works across bins. If a padname is given, the link is done with these pads. If
+no pad names are given all possibilities are tried and a matching pad is used.
+If multiple padnames are given, both sides must have the same number of pads
+specified and multiple links are done in the given order.
+.br
+So the simplest link is a simple exclamation mark, that links the element to
+the left of it to the element right of it.
+.br
+Linking using the : operator attempts to link all possible pads between
+the elements
+.br
+
+.B Caps
+
+MEDIATYPE \fI[, PROPERTY[, PROPERTY ...]]]\fR \fI[; CAPS[; CAPS ...]]\fR
+
+Creates a capability with the given media type and optionally with given
+properties. The media type can be escaped using " or '.
+If you want to chain caps, you can add more caps in the same format afterwards.
+
+.B Properties
+
+NAME=\fI[(TYPE)]\fRVALUE
+.br
+in lists and ranges: \fI[(TYPE)]\fRVALUE
+
+Sets the requested property in capabilities. The name is an alphanumeric value
+and the type can have the following case-insensitive values:
+.br
+- \fBi\fR or \fBint\fR for integer values or ranges
+.br
+- \fBf\fR or \fBfloat\fR for float values or ranges
+.br
+- \fBb\fR, \fBbool\fR or \fBboolean\fR for boolean values
+.br
+- \fBs\fR, \fBstr\fR or \fBstring\fR for strings
+.br
+- \fBfraction\fR for fractions (framerate, pixel\-aspect\-ratio)
+.br
+- \fBl\fR or \fBlist\fR for lists
+.br
+If no type was given, the following order is tried: integer, float, boolean,
+string.
+.br
+Integer values must be parsable by \fBstrtol()\fP, floats by \fBstrtod()\fP. FOURCC values may
+either be integers or strings. Boolean values are (case insensitive) \fIyes\fR,
+\fIno\fR, \fItrue\fR or \fIfalse\fR and may like strings be escaped with " or '.
+.br
+Ranges are in this format:  [ VALUE, VALUE ]
+.br
+Lists use this format:      { VALUE \fI[, VALUE ...]\fR }
+
+.SH "PIPELINE EXAMPLES"
+
+The examples below assume that you have the correct plug-ins available.
+In general, "pulsesink" can be substituted with another audio output
+plug-in such as "alsasink" or "osxaudiosink"
+Likewise, "xvimagesink" can be substituted with "ximagesink", "glimagesink",
+or "osxvideosink". Keep in mind though that different sinks might
+accept different formats and even the same sink might accept different formats
+on different machines, so you might need to add converter elements like
+audioconvert and audioresample (for audio) or videoconvert (for video)
+in front of the sink to make things work.
+
+.B Audio playback
+
+Play the mp3 music file "music.mp3" using a libmpg123-based plug-in and
+output to an Pulseaudio device

+
+.SH "ENVIRONMENT VARIABLES"
+.TP
+\fBGST_DEBUG\fR
+Comma-separated list of debug categories and levels (e.g.
+GST_DEBUG=totem:4,typefind:5). '*' is allowed as a wildcard as part of
+debug category names (e.g. GST_DEBUG=*sink:6,*audio*:6). Since 1.2.0 it is
+also possible to specify the log level by name (1=ERROR, 2=WARN, 3=FIXME,
+4=INFO, 5=DEBUG, 6=LOG, 7=TRACE, 9=MEMDUMP) (e.g. GST_DEBUG=*audio*:LOG)
+.TP
+\fBGST_DEBUG_NO_COLOR\fR
+When this environment variable is set, coloured debug output is disabled.
+.TP
+\fBGST_DEBUG_DUMP_DOT_DIR\fR
+When set to a filesystem path, store 'dot' files of pipeline graphs there.
+These can then later be converted into an image using the 'dot' utility from
+the graphviz set of tools, like this: dot foo.dot \-Tsvg \-o foo.svg (png or jpg
+are also possible as output format). There is also a utility called 'xdot'
+which allows you to view the .dot file directly without converting it first.
+.br
+When the pipeline changes state through NULL to PLAYING and back to NULL, a
+dot file is generated on each state change. To write a snapshot of the
+pipeline state, send a SIGHUP to the process.
+.TP
+\fBGST_REGISTRY\fR
+Path of the plugin registry file. Default is
+~/.cache/gstreamer\-1.0/registry\-CPU.bin where CPU is the
+machine/cpu type GStreamer was compiled for, e.g. 'i486', 'i686', 'x86\-64', 'ppc',
+etc. (check the output of "uname \-i" and "uname \-m" for details).
+.TP
+\fBGST_REGISTRY_UPDATE\fR
+Set to "no" to force GStreamer to assume that no plugins have changed,
+been added or been removed. This will make GStreamer skip the initial check
+whether a rebuild of the registry cache is required or not. This may be useful
+in embedded environments where the installed plugins never change. Do not
+use this option in any other setup.
+.TP
+\fBGST_PLUGIN_PATH\fR
+Specifies a list of directories to scan for additional plugins.
+These take precedence over the system plugins.
+.TP
+\fBGST_PLUGIN_SYSTEM_PATH\fR
+Specifies a list of plugins that are always loaded by default.  If not set,
+this defaults to the system-installed path, and the plugins installed in the
+user's home directory
+.TP
+\fBGST_DEBUG_FILE\fR
+Set this variable to a file path to redirect all GStreamer debug
+messages to this file. If left unset, debug messages with be output
+unto the standard error.
+.TP
+\fBORC_CODE\fR
+Useful Orc environment variable. Set ORC_CODE=debug to enable debuggers
+such as gdb to create useful backtraces from Orc-generated code.  Set
+ORC_CODE=backup or ORC_CODE=emulate if you suspect Orc's SIMD code
+generator is producing incorrect code.  (Quite a few important
+GStreamer plugins like videotestsrc, audioconvert or audioresample use Orc).
+.TP
+\fBG_DEBUG\fR
+Useful GLib environment variable. Set G_DEBUG=fatal_warnings to make
+GStreamer programs abort when a critical warning such as an assertion failure
+occurs. This is useful if you want to find out which part of the code caused
+that warning to be triggered and under what circumstances. Simply set G_DEBUG
+as mentioned above and run the program in gdb (or let it core dump). Then get
+a stack trace in the usual way.
+.
+.SH FILES
+.TP 8
+~/.cache/gstreamer\-1.0/registry\-*.bin
+The plugin cache; can be deleted at any time, will be re-created
+automatically when it does not exist yet or plugins change. Based on
+XDG_CACHE_DIR, so may be in a different location than the one suggested.

+Official Windows binaries for each release can be found at:
+
+  https://gstreamer.freedesktop.org/data/pkg/windows/
+
+
+Building with MinGW/MSys
+------------------------
+
+Should work out of the box from the toplevel directory using the standard
+Unix build system provided.
+
+This build type is officially supported.
+
+You can build Windows binaries including all required dependencies
+using the 'cerbero' build tool:
+
+  http://cgit.freedesktop.org/gstreamer/cerbero/
+
+This works both natively on Windows or as cross-compile from Linux.
+
+
+Building with Visual Studio
+---------------------------
+
+Building with Visual Studio is possible using the Meson-based build
+definitions, but there is currently no support for this in cerbero yet,
+so it's not for the faint-hearted.
