As of build 184.108.40.2069, Viinex officially supports a component named "Viinex Virtual Camera" on Windows platform. Viinex Virtual Camera is a DirectShow filter which implements a video source API, and is seen just like a web camera to the videoconferencing and other desktop software as Skype, Zoom, you name it, and also by browsers including Chrome, Firefox, Edge (in case if videoconferencing user interface is web-based).
So Viinex Virtual Camera is a virtual webcam to all the other desktop software. Where does the video data come from to that webcam, then? The answer is: from any live video source you might want to connect to Viinex, or even from several of them simultaneously. Virtual Camera component is essentially a DirectShow interface for a video renderer object which should be created in Viinex configuration. That video renderer may be configured to display an arbitrary layout of live video channels, optionally with a background image and an overlay (an HTML rendered over the video). The layout displayed in the video renderer may be controlled in the runtime, which makes it possible to switch between channels, or focus on a specific video channel while keeping the other video streams still visible.
Viinex Virtual Camera is an easy way to use one or a set of ONVIF compliant IP video cameras as a webcam. We perceive this as a convenient option for meeting rooms, because the deployment of an IP camera is more robust and cheap solution than other alternatives, like using active USB extension cables for the webcams with USB interface.
