/* a base class for simple audio sinks.
|
|
*
|
|
* This base class only requires subclasses to implement a set
|
|
* of simple functions.
|
|
*
|
|
* - open: open the device with the specified caps
|
|
* - write: write the samples to the audio device
|
|
* - close: close the device
|
|
* - delay: the number of samples queued in the device
|
|
* - reset: unblock a write to the device and reset.
|
|
*
|
|
* All scheduling of samples and timestamps is done in this
|
|
* base class together with the GstBaseAudioSink using a
|
|
* default implementation of a ringbuffer that uses threads.
