THANK YOU ALL!

It was a problem with my docker compose file! I didn’t list the needed devices from the jellyfin documentation. I thought the Container was detecting the gpu but it wasn’t. Docker exec <container-name> nvidia-smi is your friend!

Edit: so now it doesnt kick me out saying the playback failed but its just a black screen with 4k media

Edit 2: my bad forgot to enable some transcoding settings in jellyfin lol

This is what thay compose looks like now:

 services:
  jellyfin:
    image: jellyfin/jellyfin
    user: 1000:1000
    network_mode: 'host'
    volumes:
      - /DATA/AppData/jellyfin/config:/config
      - /DATA/AppData/jellyfin/cache:/cache
      - /DATA/AppData/jellyfin/media:/media
      - /mnt/drive1/media:/mnt/drive1/media
      - /mnt/drive2/Jellyfin:/mnt/drive2/Jellyfin
      - /mnt/drive3:/mnt/drive3
      - /mnt/drive4/media:/mnt/drive4/media
      - /mnt/drive5/jellyfin:/mnt/drive5/jellyfin
      - /mnt/drive6/jellyfin:/mnt/drive6/jellyfin
    runtime: nvidia
    deploy:
      resources:
        reservations:
          devices:
            - driver: cdi
              device_ids:
               - nvidia.com/gpu=all
            - /dev/nvidia-caps:/dev/nvidia-caps
            - /dev/nvidia0:/dev/nvidia0
            - /dev/nvidiactl:/dev/nvidiactl
            - /dev/nvidia-modeset:/dev/nvidia-modeset
            - /dev/nvidia-uvm:/dev/nvidia-uvm
            - /dev/nvidia-uvm-tools:/dev/nvidia-uvm-tools
              count: all
              capabilities: [gpu]

Edit: when I try and compose up it says “yaml: lin 30 mapping values are not allowed in this context” when I remove line 30 and 31 the output is “validating /DATA/AppData/jellyfin/docker-compose.yml: services.jellyfin.deploy.resources.reservations.devices.1 must be a mapping”

I tried this and it says:

OCI runtime exec failed: unable to start container process: exec: “nvidia-smi”: executable file not found im $PATH: unknown

I ran it as two commands instead of one before and still got that error message.

However, I tried again with a different jellyfin image and the command seems to have ran fine.

Here is a pic of my nvidia-smi output:

I followed this guide and seemed to get it working.

https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html

However jellyfin transcoding sttill doesn’t work. I have tried adding the “nvidia devices= all” environment variable, it still didn’t work.

I tried using the docker conpose from here

https://jellyfin.org/docs/general/administration/hardware-acceleration/nvidia/#configure-with-linux-virtualization

But when I try and run this command: “docker exec -it jellyfin ldconfig sudo systemctl restart docker”

It says the container is restarting and to try again when the container has started.
