intel Quicksync in docker

Just uploaded some new media to my server, and noticed that the hardware transcoding doesn't seem to be working. I'm running immich in docker on a linux server, with an integrated intel graphics card, and I've got the hwtranscoding file already set up. However, it doesn't seem to be in use; intel_gpu_top is looking empty, which makes me think its reverting to CPU (and the slowness + fans kicking off seem to confirm it!) One thing i noted; it doesnt look like quicksync is setting up the render group for the /dev/dri/render0 device. How confident are we on the docker/quicksync set up right now? Has anyone had any experience with this yet? Happy to be the guinea pig and see how adding those groups change things as soon as this import completes, but wanted to see if this was an issue others have faced!

I added the following to the quicksync service in hwaccel.transcoding.yml, which seemed to fix it; intel_gpu_top showed good usage, and things were far far speedier.
groups:
- video
- 104
groups:
- video
- 104
I used 104 because that's the ID of my current render group, and it looks like there isn't a render group in the current image. I'm guessing we can't add a render group to the image, as the ID needs to match the host. Could this be something that should be requested from users when setting up their container, potentially via an envvar?
