Jellyfin cannot load CUDA

[Big0]

Hello i recently installed jellyfin and configured hardware acceleration with a nvidia gtx950 everything works fine except when trying to run 4k movies i tried to run a 4k movie once it worked then tried it again and it stopped working i tried on different 4k movies but doesn’t work. I already asked on truenas forum but they found nothing really so im asking here i already checked compatibility with my gpu and cuda is installed i also checked that my nvidia pod didn't crash but it worked perfectly so if someone can help i would appreciate it. 
here is the jellyfin log:
FFmpeg.Transcode-2024-09-23_14-46-07_6f26e08627b75b44e67ca0320c9d464f_4fbab8fc.log&api_key=a60001001 - Pastebin.com 1

and here is the post i made on truenas forum if it helps: https://forums.truenas.com/t/jellyfin-ca...cuda/13918

Can you share your docker compose file? Also, did you install the container toolkit (looks like you did)? And also the nvidia decode and encode packages?

well im on truenas scale and it uses kubernetes so i dont know how i would show you my docker compose file and i cant install packages via shell on truenas because its disabled by default but im pretty sure ffmpeg works because i could play 4k content once and then i couldnt.

I'd have to see a ffmpeg log from when it worked to see what was different.

Also, are you are using the "app" for Jellyfin since you mentioned it was kubernetes based. You could use TrueNAS's Docker capability and skip the kubernetes.

How do i check the ffmpeg log when something works because i only see error logs. And truenas said that they would release a new update in october which will make the switch to docker so for that i can wait.

If there is no ffmpeg log for videos that work, that means the client is direct playing them.

Doesn't TrueNAS already have some variety of docker capability? "Container Manager" or something like that?

That means HW acceleration doesnt work. even though i activated transcoding and all its weird

[TheDreadPirate]

If a client can play the file unmodified then Jellyfin won't transcode. It will just send the file as is. Enabling hardware accelerated transcoding does not mean it will always transcode every file all the time. Transcoding is a fallback when directly playing the file isn't possible due to codec compatibility, bit rate limits, etc.

I tried to play 4k content while transcoding was disabled and it works but now i want to be able to play it with transcoding.
