📝 Provide a clear and concise description of the issue.

I am using Jellyfin as LXC container thanks to the script. Installed it, configured it and used for a lot of weeks already. However, since today I am not able to transcode videos using an NVIDIA GPU. Nothing was touched or changed. The .conf of the LXC container is as follows:

From what I can understand of the logs, there is something wrong with CUDA. However, I have no idea what happened.

🔄 Steps to reproduce the issue.

I have no idea how to reproduce it.

❌ Paste the full error output (if available).

the jellyfin log shows this error:

and the specific playback log shows:
[AVHWDeviceContext @ 0x5b728ecb6040] cu->cuInit(0) failed -> CUDA_ERROR_UNKNOWN: unknown error Device creation failed: -542398533. Failed to set value 'cuda=cu:0' for option 'init_hw_device': Generic error in an external library Error parsing global options: Generic error in an external library

and the video playback ends up with the following error:

Playback Error
Playback failed due to a fatal player error.

After further testing I can confirm this is not a problem with the script, but with loading NVIDIA GPU after restarting proxmox host. After executing nvidia-smi on proxmox host, everything is alright. Please close this issue and sorry for bothering everybody else with me being dumb.

We dont Install cuda and dont pass cuda drivers? We've never done that before either.

@devdecrux this might help you, I ran into some oddities when setting up transcoding with an NVIDIA GPU on the host https://gist.github.com/marcusboon/55c347ad2bab1331b4e18cfc1f0c36ba#resolve-the-oddity-that-nvidia-uvm-does-not-get-created-on-boot

The same problem solved after rebooting.

[devdecrux]

How are you loading the nvidia drivers upon booting? Because for me the only solution at the moment after restart is to execute nvidia-smi and then start the jellyfin. Otherwise, the nvidia gpu is not found as a device generally.

[marcusboon]

Did you read through the gist that I linked? It should be a complete (albeit slightly outdated solution)

I don't quite understand. I am using Ubuntu and after upgrading to the Linux kernel version, I encountered the same problem. After that, a simple reboot solved it

Yes, I did and that's how I fixed it (just slight smaller things I did outside of the mentioned in what you linked). Very thankful by the way! However, I am still baffled why this is not done automatically by the distro or nvidia devs... to load the drivers appropriately.

I don't know either. For me it didn't work. How did you install the nvidia driver? Using apt or by downloading from nvidia website?

i convert this to discussion, i would close it, but maybe other users dont see it
