QtCAM

What QtCAM is

QtCAM is free, open-source Linux webcam software from e-con Systems, founded in 2003 and headquartered in Chennai, India. It captures and displays video from cameras supported by the Linux UVC driver or compatible with V4L2. The Qt Quick interface can connect up to six cameras and stream them simultaneously. 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, camera-supported UVC controls, and more than ten cited image settings, including color-space switching. Still captures can be saved as JPG, PNG, RAW, or BMP files to a selected location. Listed video encoders are YUV, MJPEG, H264, and VP8, with MKV and AVI containers. Preview format and resolution are selectable, and frame count and FPS information can be viewed. Extension settings support selected e-con cameras. QtCAM uses GPLv3, links source code on Launchpad, and lists compatibility with specified Jetson and JetPack/L4T versions.
