Hardware Acceleration

[LAB77]

Hi all. Need some help please.

I cannot seem to get HW Acceleration working!

I'm running Ubuntu and running Jellfin in a docker container. I'm also using docker compose. Here's my compose file:

Code:

version: "3"
services:
  jellyfin:
    image: lscr.io/linuxserver/jellyfin:latest
    container_name: jellyfin
    group_add:
      - "110"
      - "render"
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    network_mode: 'host'
    volumes:
      - jellyfin-config:/config
      - /home/jelly/media:/media
    devices:
      - /dev/dri/renderD128:/dev/dri/renderD128
    ports:
      - 8096:8096

The render group is "110"

When I run "docker exec -it jellyfin /usr/lib/jellyfin-ffmpeg/vainfo" I get:
Trying display: drm
error: failed to initialize display

What am I doing wrong?

/dev/dri/renderD128 should be just /dev/dri

see docs https://docs.linuxserver.io/images/docke...celeration

Remove the "-render" line. That is taken care of with -110. You need to make sure that all the drivers are installed on the host. Also make sure that the codecs you've checked in Dashboard > Playback are codecs your iGPU can decode.

Can you share your ffmpeg log?

How do I "Can you share your ffmpeg log?"?

[TheDreadPirate]

In the container path /config/log there will be a bunch of files titled FFMPEG-Transcode<random string>.log. Pick one and attach it to a post or post it to sourcebin.

I had to zip it!

Since you are running the container as 1000/1000, did you add that user to the render group?

[LAB77]

No idea. How can I check and how do i do that?

[TheDreadPirate]

Code:

id yourUsernameHere

It will then list the groups your user is a part of. If "render" is not in the group list.

Code:

sudo usermod -aG render yourUsernameHere

[LAB77]

Just tried that and after adding the user to render, it still didn't work :-(
