SOLVED: Not possible to play media when NVIDIA NVENC

[MutzelBruzzel]

Hi folks,

I just got my new 'mini PC (intel i5-10300H / NVIDIA RTX 2060-mobile)' for jellyfin, but unfortunately it's not working as intended:

- Using only the CPU results in lags and 100% usage -> Ok nvm
- Using the NVIDIA NVENC (with H264, VC1, HEVC 10bit and VP9 10bit) results in an error message.

Trancsoder-log:

'nvidia-smi' says:

NVIDIA-SMI 550.127.08            Driver Version: 550.127.08    CUDA Version: 12.4 

I am using the jellyfin docker and my 'docker-compose.yaml' looks like this:

                                   
services:
  jellyfin:
    image: lscr.io/linuxserver/jellyfin:latest
    container_name: jellyfin
    environment:

    volumes:

What did I do wrong?
