MV Demultiplexer DirectShow Filter

The MontiVision Demultiplexer filter demultiplexes the frames of the input stream to its output pin. One example for usage of this filter is to demultiplex the video stream of some surveillance hardware that alterantly captures images from its input channels. Frame one will be send to output pin 1, frame two to output two and after a frame is send to the last output pin, it will restart at the first output pin.
