SOLVED: HEVC playback not working (fatal playback error)

[VanKurt]

I am running Jellyfin 10.9.6 on Docker (Ubuntu Server on a Proxmox VM).
The iGPU (Intel N100) is (hopefully) correctly passed through to the VM.
In the Jellyfin settings I have enabled hardware acceleration via Intel QuickSync (QSV).

What works:
I can play back all kinds of videos, including H264 encoded material. No problem at all.

What does not work:
Playing back HEVC / H265 content does not work. It gives me the error: Playback failed due to a fatal player error.

In the logs I can find the following output:

I also have attached full log files from the docker container and the Web UI below.

Can anyone help me figure this out? Thank you :-)

Can you show us your docker compose file?

Also, do you have IOMMU/VTd enabled in your BIOS?

Also, is it a VM or an LXC?

[VanKurt]

Aye,
here's the docker compose:

Code:

version: "3"
services:
  jellyfin:
    container_name: jellyfin
    image: jellyfin/jellyfin:latest
    network_mode: host
    environment:
      TZ: 'Europe/Berlin'
    ports:
      - 8096:8096
    volumes:
      - '/volume1/docker/jellyfin/config:/config'
      - '/volume1/docker/jellyfin/cache:/etc/cache'
      - '/volume1/videos/Movies:/Media/Movies'
      - '/volume1/videos/TVShows:/Media/TVShows'
      - '/volume1/music/Albums:/Media/Music'
    restart: unless-stopped

IOMMU/VTd should be enabled. Also it's a VM, not a LXC.

You did not pass GPU into the container. Add this to your docker compose.

Code:

devices:
  - /dev/dri/:/dev/dri/

[VanKurt]

Yes, you were right. I just went through the docs once more. This is how my docker compose looks now:

Code:

version: "3"
services:
  jellyfin:
    container_name: jellyfin
    image: jellyfin/jellyfin:latest
    network_mode: host
    environment:
      TZ: 'Europe/Berlin'
    group_add:
      - "993"
    devices:
      - /dev/dri/renderD128:/dev/dri/renderD128
    ports:
      - 8096:8096
    volumes:
      - '/volume1/docker/jellyfin/config:/config'
      - '/volume1/docker/jellyfin/cache:/etc/cache'
      - '/volume1/videos/Movies:/Media/Movies'
      - '/volume1/videos/TVShows:/Media/TVShows'
      - '/volume1/music/Albums:/Media/Music'
    restart: unless-stopped

Now it's working perfectly. Thank you so much
