3) Create a graph in graphedit with the mpv as your input. Go to graph > insert filters > directshow filters, add the elecard MPEG demultiplexer and the Sonic Cinemaster Video Decoder. Link the vc1 stream's output pin to elecard MPEG-2 demultiplexer, you will see a VC1 output pin appear on it. Elecard and Sonic demuxers are the only two directshow plugins which recognize VC1, but Sonic's gives an improper frame rate. Connect the VC1 output pin to the sonic cinemaster decoder input pin.
