QSV not working any more

[Islam]

Hoping someone can help get QSV running.

It was previously working on v10.10.3 on Intel 8th gen iGPU, but after changing to 15th gen iGPU transcoding results in Playback Error.

Then also updated to latest v10.10.7 with the additional environment variable for opencl:

services:
  jellyfin:
    image: lscr.io/linuxserver/jellyfin:latest
    container_name: jellyfin
    environment:
      - DOCKER_MODS=linuxserver/mods:jellyfin-opencl-intel

but still getting same error.

Also tried:

devices:
      - /dev/dri:/dev/dri
      - /dev/dri/renderD128:/dev/dri/renderD128
      - /dev/dri/card0:/dev/dri/card0

and User added to render and video groups too as before, but still same issue.

Any help would be appreciated.

TIA
