Intel Arc Subtitle Issue - ajkid93 - 2024-08-04
Intel ARC doesn't seem to work when enabling hw decoding/transocding and enabling subtitles with playback. However when disabled hw accelerated decoding the hw accelerated encode works. It is just when I have hw decoding enabled. Media is h264 and subtitles are pgssub. So ideally it would work with hw decoding.
It is a VM with gpu passthrough and jellyfin is a docker container in the vm. For reasons, I have to do it this way because I spent 4 hours trying to get the native app (non docker) to work with encoding but it refused. Prior to switching to the vm docker I was running it as a truenas app and it worked flawlessly.
Anyways, for reasons I do not want to go into I really don't want to go back to truenas app. I had this present setup working well for a year with a 3050 but switched to arc. Seems to be an arc issue specifically.
Hoping someone that can point me into the right direction about arc and pgsubs fix.

Is this in a VM inside of Truenas Scale?

It is in truenas scale.

What OS is the VM running and what kernel is it using?
RE: Intel Arc Subtitle Issue - ajkid93 - 2024-08-04
6.8.0-39-generic
Ubuntu 24.04

You need to roll back to 6.8.0-36. Starting with -38 Ubuntu's kernel inherited an upstream kernel bug that breaks transcoding almost completely for Arc GPUs. One of the Jellyfin devs and I submitted a bug report to Ubuntu asking them to back port a couple of patches to resolve the issue. But the kernel with both patches hasn't been released yet.

It is working as intended now. Thanks much!
RE: Intel Arc Subtitle Issue - TheDreadPirate - 2024-09-10
Ubuntu released 6.8.0-44 with all the patches that fix this issue.
