One luminance and one chrominance plane with alternating chroma samples as opposed to ``V4L2_PIX_FMT_YVU420`` Description =========== These are two-plane versions of the YUV 4:4:4 format. 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`
