The problem here is that your server is not receiving the frequent RTCP "RR" reports that the client (both "testRTSPClient" and "openRTSP") is sending.  Because you say that your server is built using the LIVE555 library, this surprises me.

Does your server stream via multicast - i.e., using a "PassiveServerMediaSubsession", like the "test*Streamer" demo applications in the "testProgs" directory?  If so, then your server *must* create a "RTCPInstance" object along with each "RTPSink" object (as you can see in the "test*Streamer" example code).

Or does your server stream via unicast - i.e., using a (subclass of) "OnDemandServerMediaSubsession" - as demonstrated by the "testOnDemandRTSPServer" demo application (or by the "LIVE555 Media Server")?  If so, then I can't see how you could be having this problem, because "OnDemandServerMediaSubsession" automatically creates "RTCPInstance" objects.

No, you're mistaken about this (unless you've modified the "RTSPServer.cpp" code, in which case you can't expect any support on this mailing list).  "testRTSPClient" (unless modified) always requests RTP/RTCP-over-UDP streaming, as does "openRTSP" (unless you explicitly give it the "-t" option).
