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?
I have solve this problem. I made two mistake:
1 I use IDirect3D9 object. It seems to use IDirect3D9Ex object is fine.
2 I locked the target surface before to call StretchRect().
I'm sorry to bother you.
