dGPU hardware acceleration not working in systems with an iGPU

[anhminhpho]

Kyoo's version

4.7.0

What happened?

Bonjour :)

In a system with an integrated GPU, Kyoo doesn't seem to have access to the dedicated GPU for hardware accelerated transcoding. Infinite loading screen, no GPU activity and no ffmpeg process running:

dGPU

iGPU

Modifying the transcoder-nvidia block in the docker-compose file according to this docker documentation fixes the bug, but I'm not sure if it's the best way to do it in this context.

          devices:
            - capabilities: [gpu]

          devices:
            - driver: nvidia
              device_ids: ['0']
              capabilities: [gpu]

Ubuntu Server 22.04
CPU with iGPU: Ryzen 7 5700G
dGPU: Nvidia GTX 1080

docker is evolving its API to handle GPU hardware acceleration, I've also seen the following used:

transcoder-nvidia:
    <<: *transcoder-base
    deploy:
      resources:
        reservations:
          devices:
            - driver: cdi
              device_ids:
                - nvidia.com/gpu=all

I think it depends on the version of the docker runtime. While we are in this transition period, I'll add something in the doc about that.
