GTK+ UVC Viewer (UNOFFICIAL)

Capture and view live video from v4l2 devices through GTK+ UVC Viewer (UNOFFICIAL), a simple grabber focused especially on Linux UVC camera drivers. It provides a GTK3 control interface for adjusting and monitoring compatible camera input while working with the video device directly.

A console-only mode is also available for users who prefer terminal-based operation. The separate control-panel mode, launched with guvcview.control-panel, exposes image controls while another application handles the video, including Ekiga, Cheese, MPlayer, and Skype. This makes the program useful for checking webcams, tuning image settings, or supplying camera controls alongside conferencing and media software.

The software runs on Linux with snapd on x86_64 (amd64) systems and is distributed as open-source software. It is published by 林博仁 Buo-ren Lin, with the current release identified as 2.0.6+pkg-f796. Cameras supporting H.264 hardware encoding can use the snap’s hardware-observe interface, while connecting removable-media permits saving files under /media and /run/media.

This is an unofficial package, so package-specific problems are directed to its GitHub issue tracker. Its combination of live viewing, camera controls, console access, and companion-app control suits Linux users working with UVC webcams and other v4l2 video sources.
