Notes:

Autofocus

Sometimes a new webcam will be "smart" and continously focus. Luckily you can turn this off in linux

Install the program you need. 

sudo apt install v4l-utils

find the name of the device you want to change. 

v4l2-ctl --list-devices

Find all the functions of that device. 

v4l2-ctl -d /dev/video2 --list-ctrls-menus

Change the ones you want. Rerun the above command to make sure it has happened. 

v4l2-ctl -d /dev/video2 --set-ctrl=focus_automatic_continuous=0
