Hardware Transcoding

[TheDreadPirate]

I seem to have the same issue hardware transcoding stopped working and ffmpeg logs tell me

I am running jellyfin through a docker container on Ubuntu noble 24.04 x86_64 with kernel 6.8.0-38-generic.
Hardware is:
CPU: AMD Ryzen 5 3600X (12) @ 4,41 GHz
GPU: Intel Arc A380 @ 2,45 GHz

@draxer - roll back the kernel to 6.8.0-36.  6.8.0-38 inherited an upstream kernel bug that breaks transcoding.  One of the jellyfin devs and I submitted a report to the Ubuntu kernel team to backport a pair of patches.

Nyanmisaka and I validated the backport worked on a test kernel.  So it should appear in a later Ubuntu kernel release.  For now stay on 6.8.0-36.  Reboot your system, press Esc after the BIOS screen if your system doesn't show the boot loader by default, select Advanced and the -36 kernel should be an option.
