  12 V4L2_PIX_FMT_YVU444M
  13 Planar formats with full horizontal resolution, also known as YUV and
  14 YVU 4:4:4
  15

  17 Description
  18 ===========
  19
  20 This is a multi-planar format, as opposed to a packed format. The three
  21 components are separated into three sub-images or planes.
  22
  23 The Y plane is first. The Y plane has one byte per pixel. For
  24 ``V4L2_PIX_FMT_YUV444M`` the Cb data constitutes the second plane which
  25 is the same width and height as the Y plane (and as the image). The Cr
  26 data, just like the Cb plane, is in the third plane.
  27
  28 ``V4L2_PIX_FMT_YVU444M`` is the same except the Cr data is stored in the
  29 second plane and the Cb data in the third plane.
  30
  31 If the Y plane has pad bytes after each row, then the Cb and Cr planes
  32 have the same number of pad bytes after their rows.
  33
  34 ``V4L2_PIX_FMT_YUV444M`` and ``V4L2_PIX_FMT_YUV444M`` are intended to be
  35 used only in drivers and applications that support the multi-planar API,
  36 described in :ref:`planar-apis`.
  37
  38 **Byte Order.**
  39 Each cell is one byte.
