Transcoding stops working after a while (ffmpeg 187)

[wwklnd]

Hi! Apologies if any of the many threads about ffmpeg error 187 contained this issue, I couldn't find an exact match when searching the forum.

I am running Jellyfin 10.10.7 in a Docker container (LSIO version) on Ubuntu 24.04.2 LTS. My server has a Ryzen 1700X, GTX1060 6GB, and 32GB RAM. When I first start the container, I am able to watch videos using hardware transcoding on the GPU without issue (confirmed that the GPU is being used via nvidia-smi and the logs.) However, after a while, I'm not sure how long, GPU transcoding stops working and trying to watch a video that requires hardware transcoding results in a fatal error and the attached log output: 
  jellyfin-errors-187.txt (Size: 22.62 KB / Downloads: 18)

It happens when I am using the Jellyfin browser client (using the Zen browser which is based on Firefox) and I believe the Jellyfin Android app. I also believe I've been able to play these videos using the Streamyfin app even when the issue has appeared in the browser client. I'm not 100% sure though, and since I just restarted the container I can't check at the moment.

Any ideas and suggestions are welcome! Sorry if I missed anything I should have added to the post, I'll happily do so on request.
