By the way, by reading RFC 3550 at §5.2 there's written

"separate audio and video streams SHOULD NOT be carried in a single RTP 
session and demultiplexed based on the payload type or SSRC fields."

How can this be achieved with live555? I currently have a single 
ServerMediaSession, with two PassiveServerMediaSubsession, one for video 
and one for data. Is this correct or should I create two ServerMediaSession?
