SOLVED: Playback Fails with VAAPI Hardware Acceleration in Docker Setup (AMD iGPU Passthrough

[alex-fl]

Hello everyone,

I recently set up Jellyfin in a Docker container and configured hardware acceleration using an AMD iGPU through a VM passthrough. I followed the official Jellyfin documentation for AMD hardware acceleration: Hardware Acceleration Guide.

However, when enabling VAAPI hardware acceleration in the Jellyfin settings, playback fails with the following error message: 
"Playback has failed due to a critical player error."

Logs:

- FFMPEG Log: https://pastebin.com/hLvu0Mkr

Docker Configuration:
Here’s my docker-compose.yml for the Jellyfin container:

Code:

services:
  jellyfin:
    image: jellyfin/jellyfin
    container_name: jellyfin
    network_mode: host
    mem_limit: 10240M
    mem_reservation: 512M
    cpus: 0.5
    user: 0:0
    group_add:
      - "105"
    volumes:
      - /data/jellyfin/config:/config
      - /data/jellyfin/cache:/cache
      - type: bind
        source: /data/downloads/media
        target: /media
    restart: unless-stopped
    environment:
      - JELLYFIN_PublishedServerUrl=https://[hidden].com/
    extra_hosts:
      - host.docker.internal:host-gateway
    devices:
      - /dev/dri/renderD128:/dev/dri/renderD128
networks: {}

I have ensured that the render group is configured correctly:

Code:

getent group render | cut -d: -f3
105

The vainfo output looks as follows:

Code:

docker exec -it jellyfin /usr/lib/jellyfin-ffmpeg/vainfo --display drm --device /dev/dri/renderD128
Trying display: drm
libva info: VA-API version 1.22.0

If they do, bad things may happen!

      VAProfileVP9Profile2            : VAEntrypointVLD
      VAProfileNone                  : VAEntrypointVideoProc

Potential Issue: 
The warning in the vainfo output appears problematic:

Code:

amdgpu: os_same_file_description couldn't determine if two DRM fds reference the same file description.
If they do, bad things may happen!

I suspect this may be causing the transcoding failure, but I'm unsure how to resolve it.

Questions:
1. Has anyone encountered a similar issue with VAAPI and AMD GPUs in Docker?
2. Are there specific configurations or troubleshooting steps I might be missing?
3. Is this warning about os_same_file_description critical, and how can it be resolved?

Thank you for your help!

Go to To Jellyfin Settings: Admin->Dashboard-> Playback-> Transcoding and uncheck "Allow encoding in AV1"

Please also state your CPU/GPU Model

I'm assuming "renoir" means they have a 4000 series Ryzen CPU.  Which has AMD VCN 2.  Codec support is listed here.

TLDR; most codecs except AV1, as you stated.
