Problem with hardware encoding in Docker - auxin7 - 2025-03-14

I set up a new homeserver with openmediavault running 7.7.1-3 (Sandworm) on the Linux 6.12.12+bpo-amd64 kernel and using an Intel i5 14400 which supports QSV (https://www.intel.com/content/www/us/en/products/sku/236788/intel-core-i5-processor-14400-20m-cache-up-to-4-70-ghz/specifications.html), and then using portainer to set up jellyfin.

I am using the standart docker compose file

Code:
services:

  jellyfin:

    image: jellyfin/jellyfin

    user: 1000:1000

    group_add:

      - "105" # Change this to match your "render" host group id and remove this comment

    network_mode: 'host'

    volumes:

      - /path/to/config:/config

      - /path/to/cache:/cache

      - /path/to/media:/media

    devices:

      - /dev/dri/renderD128:/dev/dri/renderD128

changing the render group to "105" since this is the output of " getent group render | cut -d: -f3 ".

Checking the output of vainfo within the docker givs this error:

Now I am quite stuck, hope some of you can help me. Software encoding works, but is quite expensive....

RE: Problem with hardware encoding in Docker - TheDreadPirate - 2025-03-14

From the OS, what is the output of this command?

Code:
sudo dmesg | grep i915

RE: Problem with hardware encoding in Docker - auxin7 - 2025-03-15

Thanks for coming back!

The output of the command is:

So no firmware for the GPU on the system? I thought that docker containers would come with their own kernel and are therefore independent of their host system?

RE: Problem with hardware encoding in Docker - auxin7 - 2025-03-16

Ok, the missing firmware pointed me to the right direction. I came upon this post:

https://unix.stackexchange.com/questions/556946/possible-missing-firmware-lib-firmware-i915-for-module-i915

So I ran

sudo apt-get install firmware-linux

and

sudo apt-get install firmware-intel-graphics

After that i rebooted the system and the commands from the Jellyfin instructions came back postive/green.

When using OpenMediaVault you can also get the Apt-Tool plugin and to it via the web-interface
