Multiple Windowless Video Mixing Renderers (VMR9) Sample

(this expects C:\Windows\clock.avi file to be available which is no longer the case after Windows XP – simply copy any AVI there as a replacement)

There are no WM_PAINT/WM_ERASEBKGND handlers, IVMRWindowlessControl9::RepaintVideo calls and other basically required code, instead a minimalistic snippet to make video rendered the requested way.

A Visual C++ .NET 2008 source code is available from SVN/Trac, release binary included.

    […]

    and the solution is:

    You was right! I installed the Service Pack 1 and it works!
    Very cool! Thanks for providing this code! I´m sure a lot of other people will be happy about that!
