Jellyfin stops seeing the GPU and won't play certain files until restarted

[ohshitgorillas]

Every so often, I find that Jellyfin won't serve up certain media files and needs rebooted before it will play. I have to log onto the server and run "docker restart jellyfin" after which the content plays fine.

ffmpeg logs suggest that the server can't find the graphics driver:

Code:

[AVHWDeviceContext @ 0x55ab136a6e40] cu->cuInit(0) failed -> CUDA_ERROR_NO_DEVICE: no CUDA-capable device is detected
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

Jellyfin logs are here, and ffmpeg logs are here.

You would need to check the host's system logs. All the ffmpeg and jellyfin logs are going to tell you is that the device isn't available anymore. Not why it isn't available.
