n100 docker transcoding/encoding failure - Pushkin - 2025-07-06

Hi Everyone,

I would like to ask your help. I have an n100 mini pc (Ubuntu 24.04.2 LTS) and I'm running Jellyfin (10.10.7) inside a docker container. Transcoding fails. I'm getting:

Code:
Playback Error Playback failed due to a fatal player error.

Here is the compose file:

Code:
services:
  jellyfin:
    image: jellyfin/jellyfin
    container_name: jellyfin
    user: 1001:1001
    group_add:
    - "992"
    environment:
    - TZ=Europe/Paris
    network_mode: 'host'
    volumes:
      - /etc/jelly/config:/config
      - /etc/jelly/cache:/cache
      - type: bind
        source: /storage/Movies/Films
        target: /Films
        read_only: true
    restart: 'unless-stopped'
    devices:
      - /dev/dri/renderD128:/dev/dri/renderD128

- Render group is 992:

Code:
$ getent group render | cut -d: -f3
992

- Permissions on renderD128:

Code:
$ ls -lAh /dev/dri/
total 0
drwxrwxrwx+ 2 root root        80 Jul  3 16:50 by-path
crwxrwxrwx+ 1 root video  226,  0 Jul  3 16:50 card0
crwxrwxrwx+ 1 root render 226, 128 Jul  3 16:50 renderD128

I attached the:

1, Docker logs:

Code:
[12:35:47] [ERR] [8] MediaBrowser.MediaEncoding.Transcoding.TranscodeManager: FFmpeg exited with code 218

2, The ffmpeg logs:


.txt   ffmpeg logs.txt (Size: 35.1 KB / Downloads: 10)

3, Relevant Jellyfin settings:

   

I have tried a different user as the one I'm using for the container is very limited but I still had the same issue. I have also done the pre-requisites from https://jellyfin.org/docs/general/post-install/transcoding/hardware-acceleration/intel/#configure-and-verify-lp-mode-on-linux I tried the Quikcsync as well but had the same.

I'm stuck at this stage. Could someone check this please?

Thank you in advance!!!

> [av1_vaapi @ 0x64ed9c2e3b40] No usable encoding entrypoint found for profile VAProfileAV1Profile0 (32).

N100 iGPU has no AV1 encoding support. Disabled it and try again.
