Is there any way I can set the zoom value (which defaults to 100) from the command line?
I can't find anything useful in the manpage or with the --help
$ guvcview.control-panel --help

Update:
For more context, I want to write a script that sets up my webcam when I login as a startup script.
I have figured I can save the profile and run it from the command line this way
$ guvcview -p Cam-Profile.gpfl -z
However this doesn't close Guvcview after setting up the zoom factor.
Are there other commandline tools that I can use with similar functionality?
