Increasing GPU memory on PI with HASSIO

[muzzak123]

Hi,
I've got a Raspberry PI 4B with 8 GB and a Coral USB. My camera are RSTP feeds and work fine through VLC.
In Frigate three 1080p cameras work fine but the CPU is at 90% without hardware acceleration.
When I apply hardware acceleration:
hwaccel_args: - -c:v - h264_v4l2m2m
two of my cameras go completely green.
I assume I need to increase my GPU memory but how do I do that under HASSIO ?

raspi-config

Another question, how do you access raspi-config? I tried the ssh add on in HassOS but it didn't work.
Would I have to put an SD in with Raspberry Pi OS and set it there?

Best solution is to run hass in docker so you can use raspi-config

@federicotravaini Not sure it's a real solution to rebuild your entire system with a new operating system. Like "fix your problem with Windows by installing Linux" !!

You can modify the config.txt on the SD card directly.

Thank you @blakeblackshear , I never realised that you could do that. All good now.

I use rpi4b 8G with hass and have had the same green screen problem when using either hwaccel_args: - -c:v - h264_v4l2m2m or - h264_mmal. The log message is just saying broken frame. Frigate works fine without hwaccel args. I do not use coral usb. Most of the time my cpu at 30% and temp at 41C for 3 cameras.

@blakeblackshear answer fixed it

I wished I checked this thread before I spent ages reading through dev info and configuring SSH to the root folder with public/private authentication keys...
