SOLVED: Hardware acceleration on Unraid issues

[n8jadams]

So I wonder if you're onto something with the permissions...

Code:

# From my unraid terminal as root
# ls -lart /dev/dri
total 0
drwxrwxrwx  2 root root        80 Oct 11 09:05 by-path/
drwxrwxrwx  3 root root       100 Oct 11 09:05 ./
crwxrwxrwx  1 root video 226, 128 Oct 11 09:05 renderD128
crwxrwxrwx  1 root video 226,   0 Oct 11 09:05 card0
drwxr-xr-x 16 root root      3360 Oct 11 09:08 ../

So I can see that the

Code:

video

usergroup owns /dev/renderD128 and /dev/card0, so I ran

Code:

# getent group video | cut -d: -f3
18

and I adjusted my docker-compose.yml accordingly:

Code:

version: '3'
services:
  jellyfin:
    image: jellyfin/jellyfin:latest
    container_name: jellyfin_official
    user: 99:100
    group_add:
      - "18" # output from `getent group video | cut -d: -f3` command, which ls -lart /dev/dri on Unraid gave for the devices
    environment:
      - PUID=99
      - PGID=100
      - UMASK=000
      - TZ=America/Denver
    network_mode: 'host'
    volumes:
      - /mnt/user/cloud-storage/apps/Jellyfin/media:/media # Media
      - /mnt/user/cloud-storage/apps/Jellyfin/config:/config # Jellyfin files
      - /mnt/user/cloud-storage/apps/Jellyfin/cache:/cache # Jellyfin cache
    devices:
     - /dev/dri/renderD128:/dev/dri/renderD128
     - /dev/dri/card0:/dev/dri/card0
    ports:
      - 8096:8096
    restart: unless-stopped

Interestingly, these commands seem to work, indicating that there is hardware acceleration getting to Jellyfin in Docker (running again as root from Unraid)

Use -h to get full help or, even better, run 'man ffmpeg'

In the Jellyfin admin video playback settings:
Checked "Enable hardware encoding" for: H264, MPEG2, VC1, VP8, VP9, VP9 10-bit.
Checked "Prefer OS native DXVA or VA-API hardware decoders
Checked "Enable hardware encoding"
Unchecked "Enable Intel Low-Power H.264 hardware encoder"
Unchecked "Enable Intel Low-Power HEVC hardware encoder"
Unhecked "Allow encoding in HEVC format"
Everything else was default.

Unfortunately the same thing is happening. The video just doesn't start playing for a very long time:
