Hi there, I unfortunately have to stream from behind a proxy. It works on one of my machines thanks to redsocks. The RTMP handshake goes well, and I can stream to twitch or youtube. On another machine, with the same redsocks configuration, the handshake never finishes, be it with youtube or twitch. The ffmpeg command is just a copy of an already h.264 encoded stream from rtmp to rtmp.
My question is: is there a random port opened for the negotiation? Where should I look for the blocking of the handshake? Here is the command I have and the output: ffmpeg -i "$SOURCE" -c:v copy -c:a copy -f flv "$YOUTUBE_URL/$KEY" -loglevel debug [...] Splitting the commandline. Reading option '-i' ... matched as input url with argument 'rtmp:// 192.168.1.217:1935/live/stream15'. Reading option '-c:v' ... matched as option 'c' (codec name) with argument 'copy'. Reading option '-c:a' ... matched as option 'c' (codec name) with argument 'copy'. Reading option '-f' ... matched as option 'f' (force format) with argument 'flv'.
