Hi, We have an Intel integrated graphics HD4600, Now we are developing a capture card, How can we transfer data from a capture card driver directly to an Intel integrated GPU by DMA? Out application use D3d9, Is there any api for DMA with capture card driver in d3d9? Thanks a lot!

You can use D3DFrameAllocator::LockFrame function implemented in Intel Media Samples <version>\sample_common\src\d3d_allocator.cpp to got GPU surface data pointers, Then write or read the data via the pointers by CPU.
