SOLVED: HEVC playback not working (fatal playback error)

[VanKurt]

Aye,
here's the docker compose:

Code:

version: "3"
services:
  jellyfin:
    container_name: jellyfin
    image: jellyfin/jellyfin:latest
    network_mode: host
    environment:
      TZ: 'Europe/Berlin'
    ports:
      - 8096:8096
    volumes:
      - '/volume1/docker/jellyfin/config:/config'
      - '/volume1/docker/jellyfin/cache:/etc/cache'
      - '/volume1/videos/Movies:/Media/Movies'
      - '/volume1/videos/TVShows:/Media/TVShows'
      - '/volume1/music/Albums:/Media/Music'
    restart: unless-stopped

IOMMU/VTd should be enabled. Also it's a VM, not a LXC.
