What QtCAM is

QtCAM is free, open-source webcam software for Linux that captures and previews video from devices supported by the Linux UVC driver or compatible with V4L2. Its Qt Quick interface can stream from up to six cameras at once. Version 4.0.1 supports third-party cameras and is described as compatible with e-con Systems USB 2.0 and USB 3.0 cameras. Users can adjust brightness, contrast, and camera-supported UVC controls; the maker also cites more than ten image-control settings and color-space switching. Still images can be saved in JPG, PNG, RAW, or BMP format to a selected location. Video encoders include YUV, MJPEG, H264, and VP8, while MKV and AVI are the listed containers. Users can select preview format and resolution and view frame count and FPS information. Extension settings are available for selected e-con cameras. The maker lists compatibility with specified Jetson series and JetPack/L4T versions, including Jetson Orin series on JetPack 6.2.0 and L4T 36.4.3. QtCAM is licensed under GPLv3, and e-con Systems links to source code on Launchpad.
