Think ARM the company, not ARM the architecture. It's a vendor extension for OpenCL made by ARM - <https://www.khronos.org/registry/OpenCL/extensions/arm/cl_arm_import_memory.txt>. They implement it in their drivers for Mali GPUs: I have it doing interop with the Rockchip decoder (using the recent patches for that here on the ML). - Mark _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
