Hi Mark, Did you have chance to try this sample? BTW: Alex Karvchenko waits for your review and commit for AMF context for some time. With this commit he can add more interesting things. Could you please take a look? Thanks, Mikhail > -Original Message- > From: ffmpeg-devel On Behalf

HI, I've wrote a small sample you can use: https://www.dropbox.com/s/c8m8evoao731tbm/OCLDX11Interop.zip?dl=0 If it doesn’t work - you have conflict of drivers with Intel - saw this before. Thanks, Mikhail > -Original Message- > From: ffmpeg-devel On Behalf Of > Mark Thompson > Sent:

You assume that device ID returned from regular enumeration is the same as device ID returned from clGetDeviceIDsFromD3D11KHR. It is not guaranteed and I didn't try this. Also I would add tracing to ensure that CL_CONTEXT_D3D11_DEVICE_KHR is actually set and clGetDeviceIDsFromD3D11KHR is

Re: [FFmpeg-devel] [INFO]AMD D3D11 to OpenCL interop extension for NV12 and P010 textures - split planes

It seem that the failure is not in the new extension but before, in the interop from D3D11 to OCL. It can happen in two cases: OCL device/context are created without D3D11 device or format of the texture is not supported. NV12 is supported. I went through the latest ffmpeg snapshot and found

Hi Mark. This extension was implemented while ago, so it can be used now. Thanks, Alexander сб, 26 мая 2018 г. в 19:45, Mark Thompson : > On 24/05/18 15:26, Mironov, Mikhail wrote: > > AMD has published OpenCL extension which allows split D3D11 texture > interoped as a single 2D

AMD has published OpenCL extension which allows split D3D11 texture interoped as a single 2D image into two 2D images representing Y and UV planes. https://www.khronos.org/registry/OpenCL/extensions/amd/cl_amd_planar_yuv.txt Mikhail ___ ffmpeg-devel
