Hello, I’m trying to render something in a OpenGL FBO and output the result to a DMABuf. Here is the code I’m using to check for the image content: void * virtual_addr = nullptr; NvBufferMemMap(_dmabuf_fd, 0, NvBufferMem_Read, &virtual_addr); NvBufferMemSyncForCpu (_dmabuf_…

Thanks… It works now !! My bad, I was already using pitch-linear to convert to cv::Mat in another part of the code.
