Transcoding/Hardware acceleration not working - randomuser - 2025-12-04

[*]The version of Jellyfin you are running: 10.11.3
[*]Your installation method and platform: Proxmox VE -> Ubuntu 24.04.3 Server TLS -> Official Docker container of Jellyfin (latest)
[*]What client(s) you are using and how the issue manifests: Browser (Firefox) & Jellyfin Media Player. When playing a 4K HVEC SDR video it gives me a playback error. Playing 1080p H264 SDR works like a charm (Direct Playing I can see in my playback info)

Full explanation
I am having issues with transcoding and implementing hardware acceleration in Jellyfin. I will give you outputs of all the commands that I think are relevant in this case. I have also made sure that I have enabled PCI passthrough on the Proxmox host, otherwise I'll probably couldn't get the following outputs.

All help and advice is appreciated! If you guys need more output of certain commands or logs, just tell me. I am just at a loss for now. Everything else works like a charm.
