Regarding as argus sample yuvJpeg iImage->getBufferCount()

I 'm refering to the sample code “tegra_multimedia_api\argus\samples\yuvJpeg” to get sersor image data

Image *image = iFrame->getImage();
        IImage *iImage = interface_cast<IImage>(image);
        IImage2D *iImage2D = interface_cast<IImage2D>(image);
        for (uint32_t i = 0; i < <b>iImage->getBufferCount()</b>; i++)
            const uint8_t *d = static_cast<const uint8_t*>(iImage->mapBuffer(i));
            if (!d)
                ORIGINATE_ERROR("\tFailed to map buffer\n");

            Size2D<uint32_t> size = iImage2D->getSize(i);
            CONSUMER_PRINT("\tIImage(2D): "
                           "buffer %u (%ux%u, %u stride), "
                           "%02x %02x %02x %02x %02x %02x %02x %02x %02x %02x %02x %02x\n",
                           i, size.width(), size.height(), iImage2D->getStride(i),
                           d[0], d[1], d[2], d[3], d[4], d[5],
                           d[6], d[7], d[8], d[9], d[10], d[11]);

the debug message show there are two getBufferCount. the sensor output resolution is 1280X1024
the first buffer size is 1280X1024 and the second buffer size is 640X512 .
the first is Y data and the second is CbCr, is it right?
if no, Would you please explain the two buffer for me?


Yes, it’s CbCr AKA UV planar.
