Hello, I am trying to convert images between DirectX and OpenCV, sadly I cant create an OpenCL context. I tryd debugging the code and found out calling "clGetDeviceIDsFromD3D11KHR" gives me an access violation. I was looking at the assembly code of the executed code and saw the following: image description The assembly code is the function (clGetDeviceIDsFromD3D11KHR) on the left. It tries to call a [r10 + 0x368] at the end. From looking at the memory of the function table, I do not have a function at this address in my nvopencl.dll image description I have a 1080Ti with latest drivers and was trying to get it to work for 2 days now. Im almost giving up.

Hopefully somebody can help me

Kind regards, Sen66

Alright, I removed the images. I thought they would best explain whats happening on my end as I do not really know what details one would need to help me fix my problem.

just capture the console output AS TEXT and insert it, where appropriate, please.

/and apologies, for being somewhat hard on you. you'll understand why it is so, once you try to search similar questions (and ppl might want tosearch yours)

I do not have ANY console output, I call cv::directx::ocl::initializeContextFromD3D11Device(m_pD3D11Dev); and it throws an "Access violation executing location 0x0000000000000000 within the function"

@Sen66 -- Why are you using OpenCL?
