There is a power line frequency setting in the camera that defaults to 60Hz that with my lighting and walls ends up looking pretty bad. Figure changing this might be handy for other users and the Portsdown too, it doesn't survive a reboot so will need set on startup.
You can view the current setting selecting the correct video device:
Code: Select all
v4l2-ctl -d /dev/video0 --all| grep freq
power_line_frequency (menu) : min=0 max=2 default=2 value=2
It is easy to change with:
Code: Select all
v4l2-ctl -d /dev/video0 --set-ctrl power_line_frequency=1
