Hi Guys,

I am trying to read frames from camera using the code below. I wish to know whether the format NvBufferColorFormat_YUV420 represents UV interleaved or planar.

// Acquire a Frame.
        UniqueObj<Frame> frame(iFrameConsumer->acquireFrame());
        IFrame *iFrame = interface_cast<IFrame>(frame);
        if (!iFrame)
            break;

        // Get the Frame's Image.
        Image *image = iFrame->getImage();
        EGLStream::NV::IImageNativeBuffer *iImageNativeBuffer
              = interface_cast<EGLStream::NV::IImageNativeBuffer>(image);
        TEST_ERROR_RETURN(!iImageNativeBuffer, "Failed to create an IImageNativeBuffer");

        int fd = iImageNativeBuffer->createNvBuffer(Argus::Size {m_framesize.width, m_framesize.height},
               NvBufferColorFormat_YUV420, NvBufferLayout_Pitch, &status);
        if (status != STATUS_OK)
               TEST_ERROR_RETURN(status != STATUS_OK, "Failed to create a native buffer");

Thanks

hello lamegeorge,

the color format NvBufferColorFormat_YUV420 would allocate the multi-planar buffer for image frames,
you could also get the MM API documentation by downloading the L4T Documentation, and please check the NV HW Buffer Utility API for more details.
thanks
