<p>libgstpbutils is a general utility library for plugins and applications.
It currently provides the
following:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p>human-readable description strings of codecs, elements, sources, decoders,
encoders, or sinks from decoder/encoder caps, element names, or protocol
names.</p></li>
<li class="listitem"><p>support for applications to initiate installation of missing plugins (if
this is supported by the distribution or operating system used)</p></li>
<li class="listitem"><p>API for GStreamer elements to create missing-plugin messages in order to
communicate to the application that a certain type of plugin is missing
(decoder, encoder, URI protocol source, URI protocol sink, named element)</p></li>
<li class="listitem"><p>API for applications to recognise and handle missing-plugin messages</p></li>
</ul></div>
<div class="refsect3">
<a name="id-1.2.14.3.5.4"></a><h4>Linking to this library</h4>
<p>You should obtain the required CFLAGS and LIBS using pkg-config on the
gstreamer-plugins-base-0.10 module. You will then also need to add
'-lgstpbutils-0.10' manually to your LIBS line.</p>
</div>
<div class="refsect3">
<a name="id-1.2.14.3.5.5"></a><h4>Library initialisation</h4>
<p>Before using any of its functions, applications and plugins must call
<a class="link" href="gst-plugins-base-libs-Pbutils.html#gst-pb-utils-init" title="gst_pb_utils_init ()"><code class="function">gst_pb_utils_init()</code></a> to initialise the library.</p>

<div class="refsect2">
<a name="gst-pb-utils-init"></a><h3>gst_pb_utils_init ()</h3>
<pre class="programlisting"><span class="returnvalue">void</span>
gst_pb_utils_init (<em class="parameter"><code><span class="type">void</span></code></em>);</pre>
<p>Initialises the base utils support library. This function is not
thread-safe. Applications should call it after calling <a href="/usr/share/gtk-doc/html/gstreamer-1.0/gstreamer-Gst.html#gst-init"><code class="function">gst_init()</code></a>,
plugins should call it from their plugin_init function.</p>
<p>This function may be called multiple times. It will do nothing if the
library has already been initialised.</p>
