Before someone jumps in to ask "have you tried #MotionEye?
Yes. it's too old and too unsupported for current #raspberrypi bookworm OS, and the kernel dependencies mean it won't see my camera.
#MotionEyeOS (which is diff from MotionEye!) is a black box at the command line as far as I can tell, and though I got it running, it doesn't see any camera I have.
