^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) ===========
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) This is a multi-planar format, as opposed to a packed format. The three
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) components are separated into three sub-images or planes.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) The Y plane is first. The Y plane has one byte per pixel. For
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) ``V4L2_PIX_FMT_YUV422M`` the Cb data constitutes the second plane which
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) is half the width of the Y plane (and of the image). Each Cb belongs to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) two pixels. For example, Cb\ :sub:`0` belongs to Y'\ :sub:`00`,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) Y'\ :sub:`01`. The Cr data, just like the Cb plane, is in the third
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) plane.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) ``V4L2_PIX_FMT_YVU422M`` is the same except the Cr data is stored in the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) second plane and the Cb data in the third plane.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) If the Y plane has pad bytes after each row, then the Cb and Cr planes
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) have half as many pad bytes after their rows. In other words, two Cx
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) rows (including padding) is exactly as long as one Y row (including
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) padding).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) ``V4L2_PIX_FMT_YUV422M`` and ``V4L2_PIX_FMT_YVU422M`` are intended to be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) used only in drivers and applications that support the multi-planar API,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) described in :ref:`planar-apis`.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) **Byte Order.**
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) Each cell is one byte.
