Is there any plan to support transcoding to h264 level 5.1?
I noticed that some of my 4k 60fps video doesn't play on my FireTV Cube 3rd gen.
The video is level 52, the FireTV supports level 51, so Jellyfin starts a transcode. With ultrafast profile it's 1.3x speed, producing ove 100 fps per the dashboard. But the transcoded stream doesn't actually play.
I noticed in the ffmpeg transcode log, Jellyfin passes -level 41 to ffmpeg, and level 4.1 doesn't support 4k 60fps video. My guess is that this could be a problem.
Amusingly, the problem videos play fine in the FireTV cube's Silk Browser via a plain HTML video control, so the videos don't appear to be using anything 5.2 specific.
