DX11 Video Renderer sample code is incomplete.

Question

Your ref : http://code.msdn.microsoft.com/windowsdesktop/DirectX-11-Video-Renderer-0e749100
Dear Sirs,
    So ... that project creates a DLL, which isn't a standard EVR so I have no clue how to fire it up.
Feeback states that the only way to test it is to use a closed source version of topedit in the Windows 8 SDK.
That isn't very helpful as that doesn't demonstrate how to use the thing.
Please provide sample code - the simpler the better that demonstrates how to use this DirectX11 Video Renderer or a derivative to throw a video texture on some simple geometry on the screen.
As a follow up, please demonstrate multiple video textures playing simultaneously to demonstrate the API supports this feature. If it doesn't, please add this support :)
Sorry to give you a hard time but I need a solid video API and if Windows doesn't provide one, it's time to look to other operating systems for a robust solution.
Regards,
Steve.

Media Foundation in Windows 8 added the
IMFMediaEngine interface, which can be used to very easily set up media playback without dealing with media sessions, media sources, etc. The best part is that this interface lets you set it up as a D3D11 frame server and you can just pull frames from it.
There is a
sample that shows how to do this. There is no D3D11 support in Media Foundation before Win8, which is also when this API was introduced. It was said above, but before Win8 you need to continue to transfer textures between D3D9 and D3D11.
Although it's probably not the method you want to use, since you asked, I'll add some info about the sample. The DX11 video renderer sample shows how to create a video renderer that is compatible with D3D11 hardware acceleration, but it's limited to the
most fundamental property of a video renderer: presenting a video to a window. The sample's presenter implements IMFVideoDisplayControl just like the EVR does, so you can call IMFVideoDisplayControl::SetVideoWindow in the same way to send output to a given
HWND. You can see in Presenter.h that it actually only implements SetVideoWindow and Get/SetFullscreen for this interface; the full EVR implements the entire interface.
If you wanted to modify the sample for presenting into a larger D3D scene, you would need to change the logic a bit so that the presenter would give out textures or something instead of presenting to a swap-chain. This would roughly need to happen where
the current implementation calls CPresenter::PresentFrame. Again, I think IMFMediaEngine is much simpler for your purposes, but it's certainly possible to adapt the sample if you really need the extra flexibility.
