I hope they are using our software to do the MPEG-4/RTP streaming :-)

No, to receive MPEG-4/RTP video, you should use the 
"MPEG4ESVideoRTPSource" class.  ("MPEG4GenericRTPSource" is for a 
more general RTP payload format that is (usually) used only for 
MPEG-4 *audio* RTP streams.)

Instead, call
    sessionState.source = MPEG4ESVideoRTPSource::createNew(*env, 
&rtpGroupsock, 96, 90000);
