Yes, I have it installed as a Docker container in a Debian 12 machine. My Docker compose file is something like this:

  jellyfin:
    container_name: jellyfin
    image: jellyfin/jellyfin
    group_add:
      - "105" 
      - "44"
      - "102"
    devices:
      - /dev/dri/renderD128:/dev/dri/renderD128
      - /dev/dri/card0:/dev/dri/card0

The group numbers were obtained following Jellyfin’s documentation.

You also need to configure Jellyfin from Menu > Playback. In “Hardware acceleration” I selected “Intel QuickSync (QSV)”. I have selected all but AV1 (not supported by my CPU) from “Enable hardware decoding from:” and from “Hardware encoding options:” I have enable all 3 of them.
