This seems to work with some combination of reloading the driver (./webcam/reload_driver.sh), running VLC (maybe it sets the video buffer mode?), killing firefox, and starting random browsers and going to meet. Eventually it seems to work.

The configuration I use is as follows (this may have changed with the new ini file):

/dev/video0 is the input
/dev/video1 is the output

Check to see if the driver is okay:

v4l2-compliance -d /dev/video0 -f

Check properties:

v4l2-ctl -d /dev/video0

Playback:

ffplay /dev/video1

Test writing random noise:

cat /dev/urandom > /dev/video0
