The screen resolution should already be self-described by the 
contents of the MPEG-4 video data - independent of RTP/RTSP - so any 
changes to this information should be picked up automatically by your 
decoder (if it's any good).  I.e., screen resolution is a property of 
the MPEG-4 video data, and has nothing to do with RTP, or our 
software.
