[Live-devel] Program stream decoder

[Vinod Madhav Joshi]

Thank you for your reply.
 I want to know that whether MPEG2 PS is streamed as PES or ES.
 If Elementary Stream then, whether audio and video streams are
differentiated by means of RTP header?

MPEG Program Streams are streamed as separate audio and video RTP
streams, because that's the standard way such data is streamed.

If you instead want to stream the data as a single, compbined
audio+video stream, then you would need to convert your Program
Stream data to Transport Streams first (e.g., using code simiilar to
that which we use in our "testMPEG1or2ProgramToTransportStream" demo
application).
