v4l2control is a small dialog/shell script to adjust settings on webcams. It's very simple and only has one option flag -v for version.
When you run v4l2control you are presented with a dialog screen of the settings with defaults and current setting info.
Press Enter on an option and put in a new value in the next screen.
I wrote this because I wanted to be able to change settings over ssh.
I hope it's useful
It uses v4l2-ctl so probably doesn't work for every webcam out there, just ones that use 4vl. Also at the moment it only supports one webcam device - /dev/video0.
