Hi list, I have a requirement to effectively relay a stream to a multicast IP. The source is an HTTP address streaming 1x video (H264) and 1x audio (A53 stereo). The idea would be to relay this unmodified to a multicast IP. I've tried the following:
ffmpeg -re -y -i http://10.10.10.10/stream -c copy -f mpegts "udp://239.192.1.185:5000" When I try and connect to the mulitcast stream with VLC player I get an error about "SDP required: A description in SDP format is required to receive the RTP stream". If I use rtsp instead of mpegts/udp it bombs out with the error "Could not write header for output file #0 (incorrect codec parameters ?): Network is unreachable". But I'm unsure if its possible to add an SDP description, or even if its possible to relay this video stream at all via ffmpeg. Off topic, I have been able to do this with vlc command line, but its unreliable, stops and starts, and just plain doesn't work when I try and run multiple streams. I don't have any experience really with multicast and particularly ffmpeg so I may be getting this all wrong, any suggestions gratefully recieved, thanks, Andy. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
