SOLVED: "Playback failed due to a fatal player error." (Only in Firefox)

[DeNewGuy]

Hello,
I've found a weird issue when trying to play back a file in Firefox, but on the phone app, the desktop app, and on Google Chrome the file will play without a problem.
I tried to look into the logs, but I couldn't really find anything in it.
Hoping anyone can help me get to the roots of this issue.

Here are the pastebins of the jf logs:
Jellyfin Log
FFMPEG Log

I'm running Jellyfin 10.9.11 in a linuxserver docker container.
This is running on Linux Debian 12 (Bookworm)

The platform I'm running my server on:
- Intel Core i5 12600
- ASUS Prime B660 PLUS D4
- 64GB DDR4 Corsair Vengeance RAM
- ASRock Intel Arc A750
- OS Drive: Samsung 980 512GB

My docker-compose is as follows:

Code:

jellyfin:
    image: linuxserver/jellyfin:latest
    container_name: jellyfin
    environment:
      - PUID=1007
      - PGID=1008
      - TZ=Europe/Amsterdam
      - DOCKER_MODS=ghcr.io/jumoog/intro-skipper
    volumes:

    restart: always

Thanks in advance for any help.

Replace this

Code:

devices:
      - /dev/dri:/dev/dri

with this

Code:

devices:
      - /dev/dri/renderD129:/dev/dri/renderD129

Right now you are passing in both the Arc GPU and the iGPU in your CPU. Jellyfin does not currently have a way (yet) to tell QSV which GPU to use so it uses the first available GPU, renderD128. Which is going to be your iGPU.

Thank you for your quick response.
When I try this I get an error message saying; there is no such file or directory.
When using the ls command in the dri folder I'm getting the following back:
by-path  card0  renderD128

Would the card0 be the dGPU then?

What kernel version is your host OS running?

[DeNewGuy]

What kernel version is your host OS running?

I'm running on 6.7.12+bpo-amd64

Did you setup low power encoding?

https://jellyfin.org/docs/general/admini...e-on-linux

Also, since you're using a backport kernel, did you also install all the kernel header, module, and firmware packages?

I have not setup low power encoding, because I thought it wasn't needed.
I used to run it without the dGPU, but still didn't run it with low power encoding. since the 12600 isn't a low power chip I believe.

What does using a backport kernel mean?
I'm sorry, I'm a bit unfamiliar with the kernel headers, module, and firmware packages.
Did I have an oversight in the installation of my software?

I ran the apt update && apt upgrade commands.

Again, sorry, I think this is a little above my knowledge level at the moment. 😅
Thank you very much for taking the time to help!

I have exactly the same problem, works on all my chromium based browsers but it doesn't work on the firefox as well as in the mobile app. The jellyfin log seems identical to mine as well.
My specs:
 Proxmox on i5 2400s.
 docker running inside a privileged lxc, with the iGPU passed through (both on lxc and docker)

my docker compose :

Code:

and here is the jellyfin docker error log when i click play and "Playback Error Playback failed due to a fatal player error." appears on firefox:

In comparison this is the log that shows when i click play from Edge or Brave or Chrome and the video loads instantly:

From what i gathered testing arround, only when "Enable hardware encoding" is enabled i get this problem on firefox, but if i turn it off it seems to HW acceleration takes place and the videos lag and load super slow.
Again this problem is only on firefox and mobile app. On chromium it works with Enable hardware encoding ON

Your CPU does not have much meaningful hardware acceleration. In particular, Intel dropped QSV support for that CPU a long time ago. You have to select VAAPI for hardware acceleration.

And you have to be careful with which codecs you enable for GPU accleration. Both decoding and encoding.

Thanks for the reply friend, I have everything off on decoding HW decoding, i tried and switched from OSV to VAAPI as well as V4L2, nothing seems to work on Firefox and the mobile app, but chrome works flawlessly with everything. Hardware encoding seems to be doing all the work cause without it, the videos lag all the time, 1 sec of playing 5 sec of buffering.
