related to processing multiple video streams into a single video
stream, That is, I want to take inputs from several live security
cameras and merge them onto a single video stream to be streamed out

supported. It features four inputs. Software is included with it that
might do what you want, but otherwise, being a widely supported
chipset, other applications might be available.
