In the Stream SDK v2.01 there was a "cl_d3d9.h". This header seems to be gone in the latest Stream SDK version. Why is that? Is AMD dropping d3d9 interop support?
DXVA is based on d3d9. DXVA does not support d3d10/11, not even in Windows 7. So if AMD does not support dxd9 interop then OpenCL can't be used for DirectShow/MediaFoundation purposes. That would be a major problem.
