In guvcview I can set up my webcam to be exactly how I want it to be. However, when I fire up Cheese or any browser-based video conferencing tool like Google Meet the camera image comes up with the initial settings.

Is there any way to make the configuration I set up in guvcview the default for all uses of the webcam?

Guvcview stores all options into a configuration file stored in the user home directory under .config/guvcview2/video0. The file is opened at start and it is rewritten at exit. By removing the file the default values will be loaded, and a new file will be written at exit.

The documentation for guvcview doesn't mention anything about systemwide configurations, so to make your configurations available to other apps, you can install "V4l2-ctl" using sudo apt-get install v4l-utils and create a startup script that uses v4l2-ctl commands to set your desired parameters. For instance:

v4l2-ctl --set-ctrl brightness=200
v4l2-ctl --set-ctrl auto_gain=0

After guvcview installation open gucview in a regular preview mode way and adjust your video image settings: exposure, contrast, brightness, wb, saturation, etc...

I recommend saving those settings into your profile: File->Save Profile

Then, from your terminal, run

guvcview --control-panel

or with a short flag

guvcview -z

Now check you skype, teams, zoom, etc.. You can use your software with the image settings defined in gucview.
