I have a C922 wired up to a mid-2014 Mac Mini. The system sees the
camera, /dev/video responds as expected, but when I run video(1) I
just get a window with a solid green background.
The camera works with MacOS, so I know the hardware is good, and
when I run the command the white "on the air" LEDs light up on the
camera. I have monkeyed around with different size settings, tried
poking the encoding settings, etc., to no avail. At this point,
I'm stumped. Anyone have any ideas?
