It's known that two or more applications cannot use the same stream from the same webcam at the same time. If one application captures a Vidéo source, another application cannot reach it because the source is locked. Typical example: you need to give a videoconference with two friends or partners at once. If your videoconference software does not support multiple conferences, you will have to start two instances of the same software. Unfortunately, in this case you may get into trouble because one application will translate Vidéo, and the other one will not. What is the solution? It's simple - just use WebCamSplitter. Also it is possible to use a media file instead of Vidéo capture device like a virtual camera. In Pro version one can duplicate up to 4 web cameras (or other Vidéo capture device, media sources) at a time. Features: 1) Customization of input/output resolutions 2) Digital Zoom and Pan 3) Ability to use Local Media File 4) Virtual audio device 5) Support of DV cameras 6) Text overlay option 7) Color correction control 8) Brightness and contrast leveling 9) Added audio support 10) Added grab still image function and screen capture as Vidéo source.
