[Live-devel] Add an audio sub-session makes the video stop

OK, so you have code that works: "MP3AudioFileServerMediaSubsession", and code that does not work: Your subclass of "OnDemandServerMediaSubsession".  By looking at the differences between them, it should be relatively easy, then, for you to figure out what's wrong with your code.

What happens when you try playing this "3x larger" audio file (i.e., after renaming it to have a ".mp3" filename suffix)?

I suspect that you are delivering the same MP3 frame into the downstream "MPEG1or2AudioRTPSink" more than once (so you end up with duplicate MP3 frames being sent).
