I have frigate 0.8.1-D376F6B running on a Raspberry Pi.
('vcgencmd get_mem gpu' gives the result
gpu=128M
)
Without hardware acceleration the application runs fine.
However, when I enable

ffmpeg:  
  hwaccel_args:
    # 32 bit OS
    - -c:v
    - h264_mmal

I get strange errors:

Any suggestions on what to do to resolve these errors?

I'm assuming you are seeing ffmpeg be restarted in the logs too. Is it in a continuous fail loop or does it work for a while and fail occasionally?

Thanks for looking into the matter.

I do a 'docker-compose up' and I see the errors in the terminal.
It is failing in a continuous loop.

Here is a more detailed log of what is in the output

This is what I would expect to see if there wasn't enough gpu memory available for mmal. Can you post your compose file as well?

in /boot/config.txt
I allocated more memory for mmal with the line:
gpu_mem=256

That seems to so the trick. The error messages disappeared.
Thanks for the help!
