Using DX11 and DXVA2

I am trying to test decoding a h264/h265 video (with just a single iframe) using DX11 and DXVA2. This is on windows 7 so I probably have to interop between 2 d3d11 devices, one with 11.1 feature set and the other with 9.3. My question is since there is a severe lack of samples for loading a h264 file and decoding it using DXVA, I was wondering if there is a guide for how to layout the data to feed into DXVA to decode? I've read this How do I use Hardware accelerated video/H.264 decoding with directx 11 and windows 7? as well as https://msdn.microsoft.com/en-us/library/windows/desktop/hh162912(v=vs.85).aspx but neither has any guide on how to do the above.

Thanks

If you want a working sample to understand how to feed data into DXVA, look here : MFNode. Under MFTDxva2Decoder, you will see how to feed data. It is for mpeg1/2 file format, but the same apply to H264 (with shades, of course).

EDIT

See my response : How do I use Hardware accelerated video/H.264 decoding with directx 11 and windows 7?
