Even though most Linux distributions have decent kernel support for webcams nowadays, a good utility to properly set up the webcam should come in handy.
Cameractrls is an easy-to-use and surprisingly capable, open-source GTK utility written in Python CLI that allows you to configure various aspects of your computer/laptop’s default or third-party webcams.
In short, it’s a GUI that allows you to configure the camera exposure, the white balance, brightness, and contrast levels, as well as more advanced settings such as the power line frequency.
Basic information about Cameractrls
We already mentioned that this is a GTK app and that it’s written in Python. However, you should also know that it can be used to set the V4L2 controls and that it’s also extendable with the non-standard controls.
Currently, the app has various extensions that should prove quite useful. These include the Logitech Extension (Led mode, Led frequency), Kiyo Pro extension (HDR, HDR mode, FoV, AF Mode, Save), as well as a a Systemd extension (Save and restore controls with the Systemd path + service).
Features and GUI rundown
One of the best things about Cameractrls is just how easy it is to use. There are three main sections: Basic, Advanced, and Capture. The Basic section is the place from where you can adjust the brightness, contrast, saturation, sharpness levels, and pretty much everything that’s also configurable via the default Cheese app (in Ubuntu).
You can also choose between two submodes such as the Aperture Priority Mode, and Manual Mode. The Manual mode allows you full control over aspects such as the exposure, backlight compensation, white balance, and toggle HDR.
The Advanced settings page allows you to select the power line frequency, toggle focus, AF mode, and adjust various configs such as Pan, Tilt, Zoom, and FoV.
Verdict
All in all, Cameractrls is a nicely designed and definitely useful little application that can really make your life a bit better when dealing with webcams on Linux.
