I personally have not tried yet on Raspberry Pi 4, but it seems it works if you have enough memory.

Which viewer is using on ML2Scratch? Currently I am only see cat and black screen only for USB camera view. I want to digging the problem.
I try to use Logitech C270. it works luvcview on RPi4 and #ML2Scratch on Windows.
So I want to digging the view path on ML2Scratch.

On Raspberry Pi 4, USB2 (Black) is working. USB3 (Blue) is not working with USB camera.
