What I want to do is

• 1.decode h264 to NV12
• 2.transform NV12 to RGB
• 3.edit the RGB.

now I am stocking in transform NV12 to RGB
I wonder if I should use VideoProcessor.

• 1.I have got the IMFMediaBuffer which contains NV12 data.
• 2.can I CreateVideoProcessorInputView using IMFMediaBuffer?
• 3.I searched that maybe I can use IMFDXGIBuffer but i should make sure it is backed by surface and I do not know how to make sure it.

the CreateVideoProcessorInputView receives ID3D11Resource and I it be IMFMediaBuffer?
