* @short_description: Simple base class for audio sinks
2011-11-11 10:52:47 +00:00
* @see_also: #GstAudioBaseSink, #GstAudioRingBuffer, #GstAudioSink.
*
* This is the most simple base class for audio sinks that only requires
* subclasses to implement a set of simple functions:
*
* * `open()` :Open the device.
*
* * `prepare()` :Configure the device with the specified format.
*
* * `write()` :Write samples to the device.
*
* * `reset()` :Unblock writes and flush the device.
*
* * `delay()` :Get the number of samples written but not yet played
* by the device.
*
* * `unprepare()` :Undo operations done by prepare.
*
* * `close()` :Close the device.
*
* All scheduling of samples and timestamps is done in this base class
2011-11-11 10:52:47 +00:00
* together with #GstAudioBaseSink using a default implementation of a
* #GstAudioRingBuffer that uses threads.
