A simple base class for audio sources.
This is the most simple base class for audio sources that only requires subclasses to implement a set of simple virtual functions:
All scheduling of samples and timestamps is done in this base class together with Gst::BaseAudioSrc using a default implementation of a Gst::RingBuffer that uses threads.
