Describe the issue/problem and steps to reproduce

Raspberry Pi 3b crashes because Motion consumes all the CPU after a while. Maybe the video processing is too much for the hardware. I am getting a warning in the logs. It suggest to change picture format to YUV420P but I dont know how to do that.

Motion log output at log_level 8

Have you allocated enough memory to the gpu under menu-preferences-ras_pi_config-performance?

[llopez]

I dont have that menu. I guess it is because rb3 b does not have GPU.

If you could provide the full log, then we could see more and try to suggest something
