[HW Accel Support]: Green screen only when using HW Acceleration

See original GitHub issue

Describe the problem you are having

Fully functioning Frigate until I try and use Hardware Acceleration on the raspberry pi 4. At this point I then get green screen on any camera that I try to use the HW Accel. Protection mode is disabled on Frigate (Full Access). I believe I have enabled GPU memory on the Pi to 512 in config.txt but this was the first time I had SSH into the root so not sure how to check it has dedicated this memory properly.
