You can't.  You would need to modify the existing source code in some 
other way - e.g., modify "networkReadHandler()" to do whatever you 
want to do with the incoming RTP packets.

Another possible approach would be to change the client to receive 
raw UDP packets (which will therefore contain all the RTP header(s)), 
rather than having the client knowingly receive RTP packets.  The 
simplest way to do this would be to change the line
	if (strcmp(fProtocolName, "UDP") == 0) {
on line 656 of "MediaSession.cpp" to
	if (True) {

If you do this, your output file should contain the complete UDP 
packet data, including the RTP headers.
