Hello, I’ve been tasked to create a QByteArray from data acquired by a camear using libargus. Previously, the data acquired was in RGBA. Then opencv was used to convert it into a cv::Mat in RGB format like so : // Get NvBuffer from native buffer m_dmabuf_fd = m_iImageNativeBuffer->createNvBuffer(…

I managed to find a solution of my own. I used NvBufferColorFormat_YUV420 instead of NvBufferColorFormat_NV12 To get the data I needed to create three pointers : unsigned char* pointer_y = NULL; NvBufferMemMap(m_dmabuf_fd, 0, NvBufferMem_Read, (void**)&pointer_y); unsigned char* pointer_u = NULL;…
