GI.GstAudio.Objects.AudioSrc

This is the most simple base class for audio sources that only requires subclasses to implement a set of simple functions:

• open() :Open the device.
• prepare() :Configure the device with the specified format.
• read() :Read samples from the device.
• reset() :Unblock reads and flush the device.
• delay() :Get the number of samples in the device but not yet read.
• unprepare() :Undo operations done by prepare.
• close() :Close the device.

All scheduling of samples and timestamps is done in this base class together with AudioBaseSrc using a default implementation of a AudioRingBuffer that uses threads.
