Couldn't Enable Hardware Acceleration with VAAPI on WSL2

[dzmbbs]

Hi, I turned on Hardware Acceleration with VAAPI on WSL2 Docker and can convert hevc to h264.

Device: Windows11 + Docker in WSL2 + Jellyfin.

---

First modify docker-compose.yml.

1. Add /usr/lib/wsl to volumes.
2. Add /dev/dxg to devices.
3. Add environment.


services:
  jellyfin:
    container_name: jellyfin
    image: jellyfin/jellyfin
    restart: always
    network_mode: host
    volumes:
      - ./config:/config
      - ./media:/media
      - /usr/lib/wsl:/usr/lib/wsl
    devices:
      - /dev/dxg:/dev/dxg
      - /dev/dri/card0:/dev/dri/card0
      - /dev/dri/renderD128:/dev/dri/renderD128
    environment:
      - LIBVA_DRIVER_NAME=d3d12
      - LD_LIBRARY_PATH=/usr/lib/wsl/lib




Then install dependencies in the jellyfin container.


apt update && apt install -y vainfo mesa-va-drivers mesa-vulkan-drivers vulkan-tools



Finally restart the container.


docker compose restart
