Currently, I was able to convert a NvBuffer directly to CPU opencv Mat by using NvBufferMemMap, NvBufferMemSyncForCpu, NvBufferMemUnMap. I was also able to convert NvBuffer to a OpenCV GpuMat by firstly converting the NvBuffer to CUEglFrame and then to OpenCV GpuMat. The second route is a little red…

Hi, For mapping to GpuMat, the pointer has to be CUDA pointer, so the CUDA function calls are required. For calling NvBufferMemMap(), can get CPU pointer and map to cv::Mat. On AGX Xavier, both GPU engine and CPU cores have good capability, so it depends on your use-case. If you need CUDA filters…

Hi, Please refer to the patches: LibArgus EGLStream to nvivafilter - #14 by DaneLLL Nano not using GPU with gstreamer/python. Slow FPS, dropped frames - #8 by DaneLLL

Hi, I checked both links you shared, but both links are doing NvBuffer → EglFrame → GpuMat route. My question is actually that is there a way to do NvBuffer → GpuMat directly. The reason I asked is that for Cpu Mat, I can use NvBufferMemMap and NvBufferMemSyncForCpu to directly map the NvBuffer to M…

Is it possible to directly map the NvBuffer to a OpenCV GpuMat?
