Unable to transcode videos - seelk - 2024-08-04
Jellyfin fails to transcode videos. This was working in the past but I am not sure what and when it changed. I'm running an LXC in Proxmox dedicated to Jellyfin. The video card is an Intel Arc A380:

Please let me know if you require additional information.
RE: Unable to transcode videos - TheDreadPirate - 2024-08-04
I'm assuming you recently updated the Proxmox kernel to 6.8.8.
Starting with kernel 6.8.5 there is a kernel bug that almost entirely breaks transcoding with Intel Arc GPUs.
You need to roll back the kernel you are running to 6.8.4. Or YOLO and push ahead to 6.9.4+, which has patches that resolve the kernel bug for Intel Arc transcoding.
See this Proxmox user's comment on rolling back.

This worked. I rolled back to 6.8.4-3-pve (from 6.8.8-1-pve) and transcoding is working. Thanks!

I'm not sure what happened but Jellyfin is no longer able to transcode, even while running kernel 6.8.4-3-pve. Logs:

Did it update the kernel without you knowing? The error in the ffmpeg looks like the kernel did update to a bugged version.
uname -a

I'm not sure if the kernel was updated. How can I tell?
Code:

Can you replicate the problem then immediately run this command?
Code:
sudo dmesg | grep i915 > /tmp/dmesg.txtThen share that text file via pastebin.

Reboot the LXC and re-run that command.

I rebooted the LXC and ran the command. It produced no results.
