I try to follow the docs but somehow it doesn’t work as expected. How does your compose file look and what to choose in the settings?

My current setup: (Not working)

services:
  # original source: https://jellyfin.org/docs/general/installation/container/
  jellyfin:
    image: docker.io/jellyfin/jellyfin:latest
    container_name: jellyfin
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/Berlin
      - JELLYFIN_PublishedServerUrl=https://my.url
    volumes:
      - ./config:/config:Z
      - ./cache:/cache:Z
      - ./media:/media:rw
    ports:
      - 8096:8096
# no need for https since reverse proxy and no local discovery
    restart: always
    device:
      - /dev/dri/:/dev/dri/:Z
      - /dev/dri/renderD128:/dev/dri/renderD128:Z
    group-add:
      - 105
    privileged: true

I do not want a privileged container but I’m experimenting.

• VAAPI is selected
• VA-API device: is set to /dev/dri/renderD128
• enable hardware decoding for : H264, HEVC, HEVC 10bit and VP9 10 bit
• enable hardware encoding
• allow encoding in HEVC

to get the group I ran getent group render | cut -d: -f3 on the host which returned 105.

$ podman exec -it jellyfin /usr/lib/jellyfin-ffmpeg/vainfo
Trying display: drm
libva info: VA-API version 1.21.0
libva info: Trying to open /usr/lib/jellyfin-ffmpeg/lib/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_21
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.21 (libva 2.21.0)
vainfo: Driver version: Intel iHD driver for Intel(R) Gen Graphics - 24.2.1 (0593864)
vainfo: Supported profile and entrypoints

This command returns VA-API does that mean I can only (or I should) select this method? Or is QSV also possible? What’s better?
