The three -components are separated into two sub-images or planes. The Y plane is -first, with each Y sample stored in one byte per pixel. For -``V4L2_PIX_FMT_NV24``, a combined CbCr plane immediately follows the Y -plane in memory. The CbCr plane has the same width and height, in -pixels, as the Y plane (and the image). Each line contains one CbCr pair -per pixel, with each Cb and Cr sample stored in one byte. -``V4L2_PIX_FMT_NV42`` is the same except that the Cb and Cr samples are -swapped, the CrCb plane starts with a Cr sample. - -If the Y plane has pad bytes after each row, then the CbCr plane has -twice as many pad bytes after its rows. - -**Byte Order.** -Each cell is one byte. - - -.. flat-table:: - :header-rows: 0 - :stub-columns: 0 - - * - start + 0: - - Y'\ :sub:`00` - - Y'\ :sub:`01` - - Y'\ :sub:`02` - - Y'\ :sub:`03` - * - start + 4: - - Y'\ :sub:`10` - - Y'\ :sub:`11` - - Y'\ :sub:`12` - - Y'\ :sub:`13` - * - start + 8: - - Y'\ :sub:`20` - - Y'\ :sub:`21` - - Y'\ :sub:`22` - - Y'\ :sub:`23` - * - start + 12: - - Y'\ :sub:`30` - - Y'\ :sub:`31` - - Y'\ :sub:`32` - - Y'\ :sub:`33` - * - start + 16: - - Cb\ :sub:`00` - - Cr\ :sub:`00` - - Cb\ :sub:`01` - - Cr\ :sub:`01` - - Cb\ :sub:`02` - - Cr\ :sub:`02` - - Cb\ :sub:`03` - - Cr\ :sub:`03` - * - start + 24: - - Cb\ :sub:`10` - - Cr\ :sub:`10` - - Cb\ :sub:`11` - - Cr\ :sub:`11` - - Cb\ :sub:`12` - - Cr\ :sub:`12` - - Cb\ :sub:`13` - - Cr\ :sub:`13` - * - start + 32: - - Cb\ :sub:`20` - - Cr\ :sub:`20` - - Cb\ :sub:`21` - - Cr\ :sub:`21` - - Cb\ :sub:`22` - - Cr\ :sub:`22` - - Cb\ :sub:`23` - - Cr\ :sub:`23` - * - start + 40: - - Cb\ :sub:`30` - - Cr\ :sub:`30` - - Cb\ :sub:`31` - - Cr\ :sub:`31` - - Cb\ :sub:`32` - - Cr\ :sub:`32` - - Cb\ :sub:`33` - - Cr\ :sub:`33` |
