Frigate - config for gpu AMD firepro?

I have spun up debian 11 VM and installed Frigate on a windows host.

It has an amd 4100 gpu.
Been trying to configure it to use the gpu but so far no success.

in the config.yml I have used:

ffmpeg:
  hwaccel_args:
    - -hwaccel
    - vaapi
    - -hwaccel_device
    - /dev/dri/renderD128

but it’s still using the cpu. I guess the /dev/… needs to point to the driver on the windows host.

Any suggestions?

Thanks
