UVC Webcam/Camera Software Guvcview 2.1.0 Released (Ubuntu PPA)

Guvcview, the free open-source tool for capturing image/video and dynamically controlling UVC camera and webcam devices, released version 2.1.0.

It’s a GTK3 and Qt5 application that provides both graphical interface and command line options to control your webcam or camera.

With it, you can change the brightness, contrast, saturation, hue, white balance (gamma), sharpness, backlight compensation, etc settings for your webcam.

Besides the dynamic control of UVC (USB Video Class) camera/webcam, it also allows to capture video with control of frame rate, filters such as mirror, invert, pieces, blur, etc. Also, capture audio with sample rate, latency, and filters including echo, reverb, fuzz, wahwah, and ducky.

These are hardware specific controls. Meaning you can use it to control your webcam/camera for other running applications. Just start it via guvcview --control_panel command, then you can do the dynamic control for OBS-Studio, Skype, and/or other Video Chatting apps.

And, guvcview 2.1.0 is the most recent version released hours ago with following changes:

• Fix audio channels deprecated warning for avcodec >= 58
• Add button click support for certain type of digital microscopes
• Fix minimum version for audio channels api deprecated warning for avcodec >= 59
• Fix COPYING to the same GPL version (v2) as the source files
• Add binary fx filter
