Transcoding on i7 4770k & GTX 770 (docker)

[TheDreadPirate]

Nvidia dropped support for that generation of GPU. You are SOL. VAAPI MIGHT work, definitely not V4L2. But don't expect much from the 770 if VAAPI does work.

The 4770k could also work, also only with VAAPI. Of the two, I would choose your iGPU over the 770.

I tested Intel QSV and now the following happens:

In docker-compose, I deleted the nvidia stuff and added this:

Code:

devices:
      - /dev/dri:/dev/dri

Setting hardware acceleration to use VAAPI instead of Intel QSV throws this error in the ffmpeg logs:

Code:

[AVHWDeviceContext @ 0x5b9c63522580] Failed to initialise VAAPI connection: -1 (unknown libva error).
Device creation failed: -5.
No device available for decoder: device type vaapi needed for codec hevc.
Stream mapping:

In your docker compose you need to pass in the render group into the container. My docker compose as an example.

Code:

services:
  jellyfin:
    image: jellyfin/jellyfin:10.9.2
    container_name: jellyfin-stable-testing
    user: 105:104
    group_add:
      - "993" # Intel render group
    network_mode: 'host'
    volumes:
      - ./jellyfin-data/config:/config
      - ./jellyfin-data/cache:/cache
      - /media/library:/media/library:ro
      - /media/storage2:/media/testLibrary:ro
    devices:
      - /dev/dri/renderD128:/dev/dri/renderD128
    restart: 'unless-stopped'
    extra_hosts:
      - "host.docker.internal:host-gateway"

On the host system you need to add the user the container is running as, looks like your user, to the render group.

Code:

sudo usermod -aG render <insert your username here>
