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:

# 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: 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?

    thx, it does not change anything.

      Hmm. I mean now reading your first output in privileged mode properly, I don’t see any errors, or am I missing something… Seems it loaded vaapi sucessfully?!

      • @swoooshOPEnglish
        2•7 months ago

        I should not need to run a container in privileged mode. What’s the container good for then?

        Yes, there is no error, yet I was not able to transcode. I had rranscode to x265 and av1 enabled. Ever since disabling av1 it works, yet I have to check again. Meaning, probably the problem was that it tried to encode to av1 and that failed. Yet I still need to run it in privileged mode.

          Hmm. I wasn’t trying to recommend privileged or non-privileged mode, just trying to use that to single in on the actual issue.

          Alright, if it’s just av1, maybe try to use a tool like vainfo to find the supported codecs. I think ffmpeg fails if an unsupported codec is explicitly specified. But take care if Encoding is mentioned. Some hardware has decoding capabilities only.

          It’s a complicated topic. And it also took me 2 whole evenings to get the permissions and everything right. I’m using systemd-nspawn, so my experience doesn’t directly translate. And it’s not any easier than docker.

          For video acceleration I found the Arch wiki somewhat helpful. But it’s lots of info and not specific to Docker. Maybe it helps anyways: https://wiki.archlinux.org/title/Hardware_video_acceleration
