I get masses of other errors from this stream, incl. TLS errors, a lot of video errors, and so on. ffplay has a native AAC decoder, you could try that as well 8as these errors come from fdk_aac, driven by an external library), but I'm sure it will also error out. > I can play the same stream with VLC or Google Chrome. Interesting. This I don't understand. (Can't reproduce right now, my Opera won't behave like Chrome and play the m3u8 directly, and I don't have VLC installed anymore.)

[FFmpeg-user] RTMP handshaking behind a proxy
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'.

Encoding to yuv420p should not make such a difference in the luminance and colours. As I understand it, FFmpeg (the libav libraries) can convert HLD and 'standard' PQ from HDR to SDR acceptably. (VLC also does the job admirably). With HLG I imagine that a LUT needs to be applied to compress the peek whites and deep blacks. I don't quite know what happens with PQ, perhaps its similar.

The colour (and luminance) which has been decoded, mapped between colour-spaces, and and re-encoded is not correct. If you have a Dolby Vision compatible TV you can see the difference very clearly.
