[Live-devel] rtsp and keeping alive connection with rtcp packets

0.0.0.0 in the SDP "c=" line (in the RTSP "DESCRIBE" response) is 
usually used only for unicast streaming. In this case, other RTSP 
messages ("SETUP") are used to specify the server address (to which 
the client should send RTCP packets).

Once again (as I noted with the previous questioner) please try using 
"openRTSP" as the client, and send us the diagnostic output, so we 
can hopefully figure out what might be going wrong.

Yes, but we should also figure out why RTP/UDP streaming doesn't 
work, and try to fix that.
