[Live-devel] On demand RTSP Unicast server question

The difference is that "MPEG1or2DemuxedServerMediaSubsession" creates its 
input source from a "MPEG1or2Demux" (which in turn reads from a MPEG 
Program Stream file), whereas the other two classes that you mentioned read 
directly from MPEG Elementary Stream files.

That's correct.  To stream a MPEG video stream, use a 
"MPEG1or2VideoFileServerMediaSubsession".  Note the code for the 
"testOnDemandRTSPServer" test program - in particular, the code for 
streaming from a MPEG Elementary Stream video file called 
"testv.mpg".  That shows you how to do this.
