No, using "testOnDemandRTSPServer" should be sufficient.  Our RTSP 
server implementation automatically supports RTP-over-TCP (for 
unicast streams), it requested.

I don't know of any issue with the code that could be causing your 
problem.  When you stream RTP-over-TCP, are you doing so using the 
same network as RTP-over-UDP?  If not, then perhaps there's something 
(e.g., a firewall) in the middle of your RTP-over-TCP network that's 
causing your problems?
