As I said before - it doesn't.  The frames that come from the 
"MPEG4GenericRTPSource" are simply AAC frames, with no extra header added.

VLC should be able to play the stream, provided that you set up the 
"MPEG4GenericRTPSink" correctly (as I noted in my previous email), and also 
provided that you are setting "fPresentationTime" correctly on each outgoing 
frame.

The best way to test this is *not* to use VLC at first, but instead to use our 
"testRTSPClient" application.  You should make sure that the "a=config" value 
in the SDP description is the same as it was in the original ('back-end') 
stream.
