Does anybody know a simple sample to use an custom allocator/presenter of the VMR9? Or to get access to the default allocator/presenter. I'm not interested in drawing on 3D-surfaces. I just want to have full control to stretching/shrinking/moving of varying input streams on the composition space of the VMR9.
Traditional custom allocator/presenter sample is \Samples\multimedia\directshow\vmr9\vmr9allocator from Windows SDK 7 (also, mentioned here). Compared to EVR presenter it is actually a simple one.
There is a scene and Direct3D inevitably involved anyway because that's VMR-9: it uses 3D device and surfaces for presentation.
