Trying to get Hardware Acceleration working

[pika]

Hey guys! I'm trying to get hardware acceleration working within my JellyFin container

Here's my setup:

Docker Container (docker-compose) for JellyFin
Host: Arch linux
GT 710 passed into container with nvidia-container-toolkit

docker-compose.yml file:

I am able to enter the container via "sudo docker exec -it ab8dc79c17ae bash" which I can then execute nvidia-smi which shows the GT 710, meaning I know it's in the container. However, there are no processes running on it.
The GT 710 I have found supports a form of NVENC, that I'm trying to use in order to significantly reduce CPU usage (it's pegged at 100% on all cores).

Here's what I'm referring to https://gssparks.github.io/post/can-a-ge...710-nvenc/ along other posts floating online.
I have followed the same steps as shown in the link, but I still get a playback error of "This client isn't compatible with the media and the server isn't sending a compatible media format."
The video in question is encoded with NVENC H.264, and is a mkv file.

Does anyone know what I am doing wrong? I know I have the kepler version of the graphics card rather than the worse version that doesn't work with this, as when I run nvidia-SMI, it reads that it's running CUDA 11.4, the same version as in the link (also has the same identifier of GK208B).

Thanks for reading!
