Vista DWM Hacking – Capture and Stream D3D/WPF Windows Real-Time

This prototype project uses undocumented Vista DWM calls to get reference to a Direct3D surface the Vista DWM uses to paint windows. The D3D surface is then able to be rendered in a WPF application like a "VisualBrush". Because this is done in the GPU, it is very efficient. The sample application will also let you stream a high quality, high fps capture of your video to Silverlight or Windows Media Player.
