SOLVED: Intel QuickSync on Docker?

[Ángel Hurtado]

So I have followed some guides that said to add to my docker compose file this

Code:

- devices:
  /dev/dri/renderD128:/dev/dri/renderD128
  /dev/dri/card0:/dev/dri/card0

And VAAPI seems to work, but not QuickSync, at least VAAPI lets me select the renderD128 in the dashboard > playback while QuickSync doesn't.

Yes, I have a modern Intel CPU, a N100, driver in Docker is 23.xx (can't recall right now) and also have it on my OS.

Using Ubuntu 24.04 Server (dev builds). Doesn't seem like a problem from Ubuntu.
I am also using the official Docker image, from Jellyfin
