Black Screen when playing media on Roku App - harexew - 2023-12-05

Im trying to play my media on a Roku Express, using the Jellyfin app. My server is running Version 10.8.9 on Windows Server 2016.
Everytime I play some media it only shows a Black Screen, on other devices (Firefox Browser on Windows 11 and Jellyfin app on Android TV) it plays without any problems. The only solution that worked for me temporatily is to run the files through ffmpeg with the following arguments.

Code:
ffmpeg.exe -i old.mp4 -c:v libx264 -crf 18 -preset slow -c:a copy new.mp4

The old and new files dont really show a difference in the media info screen.

Can you share your jellyfin and ffmpeg logs? Upload them to sourcebin and link back here.

The file it doesnt want to play is the line

Code:
[2023-12-05 22:35:44.771 +01:00] [INF] [17] Emby.Server.Implementations.Session.SessionManager: Playback stopped reported by app "Jellyfin Roku" "1.6.6" playing "Change (Alpha Episode)". Stopped at "0" ms

I was not able to find any ffmpeg logs on my machine.

Interesting. At one point it said it didn't support the codec level. Looking at the wiki for H264, level 30 (from the original file) is not appropriate for 1080p, so that may be the problem.

Yeah it seems I will have to re encode a good chunk of my library, was hoping there was an easier fix.

Do you have a GPU to accelerate it?
