When the camera is in an external IP, I want this program to connect to it via unicast and then distribute the stream to the clients in the network via multicast. Sometimes you cannot control all the routers in between to guarantee there will be multicasting availability all the way from the camera to the clients.</span></div></blockquote><div><br class=""></div>If you want to relay a unicast RTSP/RTP stream into a multicast RTSP/RTP stream, then something like the following should work:</div><div><br class=""></div><div>1/ Modify “testH264VideoStreamer.cpp” to change the “inputFileName” variable from "test.264” to “stdin”.
