No, your problem is simply that - when you called "ServerMediaSession::createNew()” to create your “ServerMediaSession” object - you didn’t set the (normally optional) “isSSM” parameter to True. Because you want source-specific multicast, you need to set that parameter to True. If you haven’t done so already, review the code for our “testH264VideoStreamer” demo application: “testProgs/testH264VideoStreamer.cpp”. Also, although it’s probably not essential, I recommend that - instead of 224.180.10.71 - you use an IP multicast address in 232/8; that’s the range that’s been specifically reserved for source-specific multicast. See RFC 4607: https://tools.ietf.org/html/rfc4607 Finally, I recommend that, at first, you use our “openRTSP” command-line RTSP client - rather than a media player like VLC - to test your server; see http://www.live555.com/openRTSP/ Ross Finlayson Live Networks, Inc. http://www.live555.com/ _______________________________________________ live-devel mailing list live-devel@lists.live555.com http://lists.live555.com/mailman/listinfo/live-devel
