How to consume ID3D11Texture2D NV12 into DPC++ ?

When using the OneVPL video decoder in Windows it creates an ID3D11Texture2D NV12, how can we use this in DPC++ ?

 

I have looked into Level-zero with zeMemAllocDevice and ZE_STRUCTURE_TYPE_EXTERNAL_MEMORY_IMPORT_WIN32 / ZE_EXTERNAL_MEMORY_TYPE_FLAG_OPAQUE_WIN32 but that generates exceptions deep in igdgmm64.dll

And using the OpenCL backend, i think creating the context with CL_CONTEXT_D3D11_DEVICE_KHR is a problem.

 

D3D11_RESOURCE_MISC_SHARED_NTHANDLE & D3D11_RESOURCE_MISC_SHARED_KEYEDMUTEX are set that way it should be possible to share the data.

 

Or is it possible to use Unified Shared Memory with the already available ID3D11Texture2D ?

 

Best Regards,

Robert
