NvBuffer to OpenCV GpuMat. Does memory is directly accessible to the device?

For NV12 format to GpuMat, you may have a look to this post:

Real-time CLAHE processing of video, framerate issue. Gstreamer + nvivafilter + OpenCV

I think I got it… Seems there is 256 bytes stride. This should be better (so far, not tested so much): static std::vector<cv::cuda::GpuMat> uv(2); static void cv_process_NV12(void** pPitch, int32_t width, int32_t height) { //printf ("cv_process_NV12 %d x %d\n", width, height); const int stride = 256; int num_strides = ((int)width)/stride; int use_width = num_strides*stride; if (use_width < (int)width) use_width += stride; int use_height = height; cv::cuda::…
