For "testMPEG4VideoStreamer", this is very simple: In the file 
"testMPEG4VideoStreamer.cpp", change the "inputFileName" variable to 
"stdin".  Or, even better, change "inputFileName" to the name of the input 
device (if your MPEG-4 encoder's stream is accessible as a file).

Quite possibly, but I can't say for sure.  The reason why I can't say for 
sure is that QuickTime supports only a subset of the MPEG-4 video 
specification, and some MPEG-4 encoders prodoce data that QuickTime can't 
handle.  (I recently had this problem with the IME6400 MPEG-4 encoder ASIC 
(manufactured by Intime Corporation).)

>If so, I understand that you need an .sdp file.

No, not necessarily, because "testMPEG4VideoStreamer" has a built-in RTSP 
server.  Note that when "testMPEG4VideoStreamer" starts up, it prints out a 
"rtsp://" URL.  You simply ask QuickTime player to play that "rtsp://" URL.

This is something that you can try right now.  PLease let us know if it 
works for you.
