Jellyfin web player can't play some transcoded files

[frankjrix]

For directory access I used bind mounts, and as for the device access I mapped the ownnership of the device to the video (for the "card" one) and the render (for the renderD128 one) groups in the container, and in fact hwa transcoding other than tonemapping works without issues.

Anyways while it would be nice to have, I'm not too concerned about tonemapping.

My main issue is with the problem video, and understanding if it's a jellyfin thing or a file issue. I tried reencoding it with ffmpeg and it still won't play on firefox. Should I open an issue on github at this point?
