[Live-devel] Doubt on multiple media subsessions

Yes.  Note that this is just what the "openRTSP" code does (see 
"testProgs/playCommon.cpp").

Just make sure that each of your 'sink' objects uses the input 
"presentationTime" value to properly synchronize the streams.

No, calling "MediaSubsession::initiate()" on each subsession is 
sufficient.  Our code automatically figures out what kind of 
"RTPSource" object to create, based on the SDP description.
