[Live-devel] On Demand RTSP Server

No.  If you want to include two media types (e.g., audio and video) within 
a single RTSP-initiated stream, then you should create just one 
"RTSPServer" object, and one "ServerMediaSession" object, but add two 
separate "ServerMediaSubsession" objects to it.  For an example of this, 
see the "vobStreamer" implementation.

Note that in a few days, I hope to install an updated version of 
"testOnDemandRTSPServer" that will show you how to do this for MPEG 1 or 2 
Program Stream files (that contain both audio and video).

Yes.  See my answer to 1.

Not for unicast streaming.  For unicast RTSP/RTP streaming, the actual 
client and server ports are chosen during the RTSP protocol ("SETUP" and 
"PLAY" operations), an are not specified in the SDPdescription returned by 
"DESCRIBE".  (However, for *multicast* sessions, this is not true - for 
multicast sessions, the port number is specified in the SDP description.)
