DirectShow Media Player with multiple Video Windows

For a Karaoke application the playwnd sample from the DirectShow SDK shall be enhanced. By using DirectShow intelligent connect a filter graph shall be constructed integrating the Infinite Pin Tee (IPT) filter and Enhanced Video Renderer (EVR) or Video Mixing Renderer 9 (VMR9) if EVR is not available on the system. In order to display two or more video windows of the same video file the IPT filter shall be connected to the appropriate number of VMR9 / EMR filters. The resulting player must be capable to playback MP4 files using appropriate decoders to be defined by the coder. The architecture of the player must be capable to playback video files to be read as a list of file names in a text file. The programming style shall avoid any memory leakage, e.g. by using smart pointers. MS Visual Studio 2008 or 2010 shall be used. The complete C++ project is a deliverable item.
