Hi,

You can check this comment for the detail:

How to create opencv gpumat from nvstream?

Hi, Please apply below code to get_converted_mat() in gstdsexample.cpp #include <cudaEGL.h> #include <opencv2/cudafilters.hpp> #ifdef __aarch64__ // To use the converted buffer in CUDA, create an EGLImage and then use // CUDA-EGL interop APIs if (USE_EGLIMAGE) { if (NvBufSurfaceMapEglImage (dsexample->inter_buf, 0) !=0 ) { goto error; } // dsexample->inter_buf->surfaceList[0].mappedAddr.eglImage // Use interop APIs cuGraphicsEGLRegisterImage and // cuGraphicsR…

To access the image buffer, it’s required to register with EGL first.
Thanks.
