Thanks for sharing! I've been using guvcview for a long time to control exposure and focus on my good old Logitech C920, but adding a ppa just for that seemed a bit too much. I will definitely have a look at it!

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Why do you need a PPA? It's packaged Debian already.... https://packages.debian.org/search?keywords=guvcview&searchon=names&suite=all§ion=all
I normally just use the Qt V4L2 test app (descriptively named qv4l2) to check how the cam image looks, but it can't set any camera-specific properties.
Just to confirm it also works with the Logitech C930e that the OP has. This is what I use it for.
Sad it is not verified on flathub 😪
