Indicate if the media stream is synchronous. If this returns true then the media stream will block of the amount of time it takes to annunciate the data. For example if the media stream is over a sound card, and 480 bytes of data are to be written it will take 30 milliseconds to complete.
Implements OpalMediaStream.
Read an RTP frame of data from the source media stream. The default behaviour simply calls ReadData() on the data portion of the RTP_DataFrame and sets the frames timestamp and marker from the internal member variables of the media stream class.
