# GstPipeline

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 should be retrieved with gst_pipeline_get_bus. This GstBus should then be used to receive GstMessage from the elements in the pipeline. Listening to the GstBus is necessary for retrieving error messages from the GstPipeline and otherwise the GstPipeline might stop without any indication, why. Furthermore, the GstPipeline posts messages even if nobody listens on the GstBus, which will pile up and use up memory.

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_set_auto_flush_bus

    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.

Parameters:

`pipeline` –

a GstPipeline

`auto_flush` –

whether or not to automatically flush the bus when the pipeline goes from READY to NULL state

#### Gst.Pipeline.prototype.set_auto_flush_bus

    }

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.
