Yes, our software implements the IETF’s RTP/RTCP standard (including the RTP payload formats for several common video and audio codecs).

We have several demo applications (in source code form) that you can try, as well as a pre-built RTSP server application.  See http://live555.com/liveMedia/#testProgs

(In particular, you can run our “openRTSP” command-line client application with the “-Q” option, to report ‘quality of service’ stats; see http://live555.com/openRTSP/#other-options
