Description
|
|
Packit Service |
963350 |
A GstPipeline is a special GstBin used as the toplevel container for
|
|
Packit Service |
963350 |
the filter graph. The GstPipeline will manage the selection and
|
|
Packit Service |
963350 |
distribution of a global GstClock as well as provide a GstBus to the
|
|
Packit Service |
963350 |
application.
|
|
Packit Service |
963350 |
gst_pipeline_new() is used to create a pipeline. when you are done with
|
|
Packit Service |
963350 |
the pipeline, use gst_object_unref() to free its resources including all
|
|
Packit Service |
963350 |
added GstElement objects (if not otherwise referenced).
|
|
Packit Service |
963350 |
Elements are added and removed from the pipeline using the GstBin
|
|
Packit Service |
963350 |
methods like gst_bin_add() and gst_bin_remove() (see GstBin).
|
|
Packit Service |
963350 |
Before changing the state of the GstPipeline (see GstElement) a GstBus
|
|
Packit Service |
963350 |
can be retrieved with gst_pipeline_get_bus(). This bus can then be
|
|
Packit Service |
963350 |
used to receive GstMessage from the elements in the pipeline.
|
|
Packit Service |
963350 |
By default, a GstPipeline will automatically flush the pending GstBus
|
|
Packit Service |
963350 |
messages when going to the NULL state to ensure that no circular
|
|
Packit Service |
963350 |
references exist when no messages are read from the GstBus. This
|
|
Packit Service |
963350 |
behaviour can be changed with gst_pipeline_set_auto_flush_bus().
|
|
Packit Service |
963350 |
When the GstPipeline performs the PAUSED to PLAYING state change it will
|
|
Packit Service |
963350 |
select a clock for the elements. The clock selection algorithm will by
|
|
Packit Service |
963350 |
default select a clock provided by an element that is most upstream
|
|
Packit Service |
963350 |
(closest to the source). For live pipelines (ones that return
|
|
Packit Service |
963350 |
GST_STATE_CHANGE_NO_PREROLL from the gst_element_set_state() call) this
|
|
Packit Service |
963350 |
will select the clock provided by the live source. For normal pipelines
|
|
Packit Service |
963350 |
this will select a clock provided by the sinks (most likely the audio
|
|
Packit Service |
963350 |
sink). If no element provides a clock, a default GstSystemClock is used.
|
|
Packit Service |
963350 |
The clock selection can be controlled with the gst_pipeline_use_clock()
|
|
Packit Service |
963350 |
method, which will enforce a given clock on the pipeline. With
|
|
Packit Service |
963350 |
gst_pipeline_auto_clock() the default clock selection algorithm can be
|
|
Packit Service |
963350 |
restored.
|
|
Packit Service |
963350 |
A GstPipeline maintains a running time for the elements. The running
|
|
Packit Service |
963350 |
time is defined as the difference between the current clock time and
|
|
Packit Service |
963350 |
the base time. When the pipeline goes to READY or a flushing seek is
|
|
Packit Service |
963350 |
performed on it, the running time is reset to 0. When the pipeline is
|
|
Packit Service |
963350 |
set from PLAYING to PAUSED, the current clock time is sampled and used to
|
|
Packit Service |
963350 |
configure the base time for the elements when the pipeline is set
|
|
Packit Service |
963350 |
to PLAYING again. The effect is that the running time (as the difference
|
|
Packit Service |
963350 |
between the clock time and the base time) will count how much time was spent
|
|
Packit Service |
963350 |
in the PLAYING state. This default behaviour can be changed with the
|
|
Packit Service |
963350 |
gst_element_set_start_time() method.

|
|
Packit Service |
963350 |
Usually, when a pipeline goes from READY to NULL state, it automatically
|
|
Packit Service |
963350 |
flushes all pending messages on the bus, which is done for refcounting
|
|
Packit Service |
963350 |
purposes, to break circular references.
|
|
Packit Service |
963350 |
This means that applications that update state using (async) bus messages
|
|
Packit Service |
963350 |
(e.g. do certain things when a pipeline goes from PAUSED to READY) might
|
|
Packit Service |
963350 |
not get to see messages when the pipeline is shut down, because they might
|
|
Packit Service |
963350 |
be flushed before they can be dispatched in the main thread. This behaviour
|
|
Packit Service |
963350 |
can be disabled using this function.
|
|
Packit Service |
963350 |
It is important that all messages on the bus are handled when the
|
|
Packit Service |
963350 |
automatic flushing is disabled else memory leaks will be introduced.

gst_pipeline_set_latency (GstPipeline *pipeline,
|
|
Packit Service |

GstClockTime latency);
|
|
Packit Service |
963350 |
Sets the latency that should be configured on the pipeline. Setting
|
|
Packit Service |
963350 |
GST_CLOCK_TIME_NONE will restore the default behaviour of using the minimum
|
|
Packit Service |
963350 |
latency from the LATENCY query. Setting this is usually not required and
|
|
Packit Service |
963350 |
the pipeline will figure out an appropriate latency automatically.
|
|
Packit Service |
963350 |
Setting a too low latency, especially lower than the minimum latency from
|
|
Packit Service |
963350 |
the LATENCY query, will most likely cause the pipeline to fail.
