I am using intel media sdk 2014 R2 in windowns 7 x64.
The directx sdk version is Microsoft DirectX SDK (June 2010). IDE is VS2010.
I want to use it to encode d3d9 rendertarget surface.
but I can't copy d3d9 surface to dxva2 surface.
The function of IDirect3DDevice9::StretchRect() always return error.
I'm sure the both surfaces has the same size and d3dformat.
How can I do about it?
