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 + :widths: 2 1 1 1 1 + + + - .. row 1 + + - start0 + 0: + + - Y'\ :sub:`00` + + - Y'\ :sub:`01` + + - Y'\ :sub:`02` + + - Y'\ :sub:`03` + + - .. row 2 + + - start0 + 4: + + - Y'\ :sub:`10` + + - Y'\ :sub:`11` + + - Y'\ :sub:`12` + + - Y'\ :sub:`13` + + - .. row 3 + + - start0 + 8: + + - Y'\ :sub:`20` + + - Y'\ :sub:`21` + + - Y'\ :sub:`22` + + - Y'\ :sub:`23` + + - .. row 4 + + - start0 + 12: + + - Y'\ :sub:`30` + + - Y'\ :sub:`31` + + - Y'\ :sub:`32` + + - Y'\ :sub:`33` + + - .. row 5 + + - + + - .. row 6 + + - start1 + 0: + + - Cb\ :sub:`00` + + - Cb\ :sub:`01` + + - Cb\ :sub:`02` + + - Cb\ :sub:`03` + + - .. row 7 + + - start1 + 4: + + - Cb\ :sub:`10` + + - Cb\ :sub:`11` + + - Cb\ :sub:`12` + + - Cb\ :sub:`13` + + - .. row 8 + + - start1 + 8: + + - Cb\ :sub:`20` + + - Cb\ :sub:`21` + + - Cb\ :sub:`22` + + - Cb\ :sub:`23` + + - .. row 9 + + - start1 + 12: + + - Cb\ :sub:`20` + + - Cb\ :sub:`21` + + - Cb\ :sub:`32` + + - Cb\ :sub:`33` + + - .. row 10 + + - + + - .. row 11 + + - start2 + 0: + + - Cr\ :sub:`00` + + - Cr\ :sub:`01` + + - Cr\ :sub:`02` + + - Cr\ :sub:`03` + + - .. row 12 + + - start2 + 4: + + - Cr\ :sub:`10` + + - Cr\ :sub:`11` + + - Cr\ :sub:`12` + + - Cr\ :sub:`13` + + - .. row 13 + + - start2 + 8: + + - Cr\ :sub:`20` + + - Cr\ :sub:`21` + + - Cr\ :sub:`22` + + - Cr\ :sub:`23` + + - .. row 14 + + - 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 + + + - .. row 1 + + - + - 0 + + - 1 + + - 2 + + - 3 + + - .. row 2 + + - 0 + + - YC + + - YC + + - YC + + - YC + + - .. row 3 + + - 1 + + - YC + + - YC + + - YC + + - YC + + - .. row 4 + + - 2 + + - YC + + - YC + + - YC + + - YC + + - .. row 5 + + - 3 + + - YC + + - YC + + - YC + + - YC |
