Coming back to this after a bit of a hiatus. I've got this working in a single application. One side creates an RTSP client, and starts all the individual streams, receiving the data into buffers. The buffers for the H264 video stream appear to have been processed to provide H264 video frames. These frames are then passed to another buffer class, used as the source for a class derived from H264VideoFileServerMediaSubsession, which is part of an RTSP stream that is made available to clients.
This approach seems to work, but there's a significant performance hit being seen. Does the data need to be converted from the raw RTP stream into H264 frames at the receiving end, only to be converted back to an RTP stream by the transmitting side? Or is it possible to remove these two conversions and just pass raw RTP data directly from the receiver to the transmitter?

Will look at that. And if I wanted to re-construct an RTSP stream from the SDP definition and the buffers of data I've collected from an RTSP client, how would I do that?

For example, look at the code for the “testRTSPClient” demo application (in the “testProgs” directory). Look at the implementation of “DummySink” (“testRTSPClient.cpp”, line 508). You would do the same thing here, except that you want to process the data that has just been read (to “fReceiveBuffer”, of length “frameSize”). >> From what I can see by tracing through the using the ProxyServerMediaSession >> class This is a ‘red herring’. You’re just writing a RTSP client, not a proxy server.
