Stream from Restream.io to RTMP sink in Restreamer only transmitted sound #723

Open DJGummikuh opened 5 months ago

DJGummikuh commented 5 months ago

Describe the bug We tried to relay a RTMP stream via Restreamer that originated from Restream.io from a professional event. The Event organizers use restream.io to stream to a multitude of targets, Twitch among them, and we asked them to also stream to our custom RTMP sink in Restreamer. However, while we got traffic that - measured by the amount - seemed to include video and audio, only audio was accessible on any targets configured. The targets were

I do unfortunately not have the logs in text form. image image

I fail to reproduce this issue on my own. restream.io only allows sending to custom RTMP targets on a paid plan (which I don't have), streaming to the same RTMP target from OBS, ffmpeg, Larix and VLC produces a working stream, including video and audio.

I am therefore not certain that this is a restreamer issue, it could either be an issue triggered by the combination of restream.io and restreamer or some strange source setting from the studio (though I don't believe this to be plausible, as they are streaming to twitch just fine via the same restream.io setup)

To Reproduce Cannot be reproduced by me, see above.

Expected behavior I expect a stream that contains video and audio to survive restreaming by restreamer, so that OBS or any other consuming software receives video alongside audio and not only audio.

Please try with the latest Restreamer version. We fixed some bugs in our RTMP and switched to ffmpeg 6.1.1.

I also don't have a paid restream.io account in order to test it. It might be that restream.io was sending the video encoded not in H264, but in some othe codec (e.g. H265, VP9, or AV1). Only as of fmpeg 6.1.1 the additional codecs are supported.

DJGummikuh commented 4 months ago

I am pretty certain they sent it in H.264, since they were streaming the same datastream also directly to multiple twitch accounts - which were receiving video just nicely (and to my knowledge, Twitch Ingest currently only supports H.264). Anyways, I will try to find someone who allows me to borrow their restream.io account ^^

I did retry with the latest Restreamer Version (datarhei-core v16.15.0 (linux/amd64) - bold-hill-3974) and I have the exact same result as before: Audio gets through, video doesn't get through. I managed to pull some more logs from the occasion:

I also talked with the person that sent the stream and he confirmed that he was sending 1920x1080 with 6000kbps x264 with 2s Keyframes and 59.94 FPS, using a Standard OBS. I tried to replace their OBS with mine, but that didn't work (had nothing to do with restreamer, my OBS started acting up all of a sudden), so I cannot with 100% certainty say whether it is restream.io that interacts with restreamer in a funny way or if their OBS is already doing something strange that causes Restreamer to not find a video signal. Restreamer DID have a constant 6000kbps Ingest, so the video signal must definitely have been part of that datastream somewhere.

I managed to do the test now with my OBS -> restream.io -> Restreamer -> my other OBS with the exact same result (Sound but no Video). OBS -> Restreamer -> Other OBS does work, so the issue must be somewhere between restream.io and Restreamer.
