The three components are separated into three sub-images or planes. The Y plane is first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_YUV444M`` the Cb data constitutes the second plane which is the same width and height as the Y plane (and as the image). The Cr data, just like the Cb plane, is in the third plane. ``V4L2_PIX_FMT_YVU444M`` is the same except the Cr data is stored in the second plane and the Cb data in the third plane. If the Y plane has pad bytes after each row, then the Cb and Cr planes have the same number of pad bytes after their rows. ``V4L2_PIX_FMT_YUV444M`` and ``V4L2_PIX_FMT_YUV444M`` are intended to be used only in drivers and applications that support the multi-planar API, described in :ref:`planar-apis`. **Byte Order.** Each cell is one byte. .. flat-table:: :header-rows: 0 :stub-columns: 0 * - start0 + 0: - Y'\ :sub:`00` - Y'\ :sub:`01` - Y'\ :sub:`02` - Y'\ :sub:`03` * - start0 + 4: - Y'\ :sub:`10` - Y'\ :sub:`11` - Y'\ :sub:`12` - Y'\ :sub:`13` * - start0 + 8: - Y'\ :sub:`20` - Y'\ :sub:`21` - Y'\ :sub:`22` - Y'\ :sub:`23` * - start0 + 12: - Y'\ :sub:`30` - Y'\ :sub:`31` - Y'\ :sub:`32` - Y'\ :sub:`33` * - * - start1 + 0: - Cb\ :sub:`00` - Cb\ :sub:`01` - Cb\ :sub:`02` - Cb\ :sub:`03` * - start1 + 4: - Cb\ :sub:`10` - Cb\ :sub:`11` - Cb\ :sub:`12` - Cb\ :sub:`13` * - start1 + 8: - Cb\ :sub:`20` - Cb\ :sub:`21` - Cb\ :sub:`22` - Cb\ :sub:`23` * - start1 + 12: - Cb\ :sub:`20` - Cb\ :sub:`21` - Cb\ :sub:`32` - Cb\ :sub:`33` * - * - start2 + 0: - Cr\ :sub:`00` - Cr\ :sub:`01` - Cr\ :sub:`02` - Cr\ :sub:`03` * - start2 + 4: - Cr\ :sub:`10` - Cr\ :sub:`11` - Cr\ :sub:`12` - Cr\ :sub:`13` * - start2 + 8: - Cr\ :sub:`20` - Cr\ :sub:`21` - Cr\ :sub:`22` - Cr\ :sub:`23` * - start2 + 12: - Cr\ :sub:`30` - Cr\ :sub:`31` - Cr\ :sub:`32` - Cr\ :sub:`33` **Color Sample Location:** .. flat-table:: :header-rows: 0 :stub-columns: 0 * - - 0 - 1 - 2 - 3 * - 0 - YC - YC - YC - YC * - 1 - YC - YC - YC - YC * - 2 - YC - YC - YC - YC * - 3 - YC - YC - YC - YC
