You don't need to do anything special to get this.  The output 
delivered by a "MPEG4ESVideoRTPSource" in response to the 
"getNextFrame()" function will be a complete MPEG-4 Video frame, 
regardless of how many RTP packets the frame took up.  Our code takes 
care of reassembling a complete video frame.
