^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) These are planar formats, 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. The Y plane
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) is first. The Y plane has one byte per pixel. For
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) ``V4L2_PIX_FMT_YVU420``, the Cr plane immediately follows the Y plane in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) memory. The Cr plane is half the width and half the height of the Y
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) plane (and of the image). Each Cr belongs to four pixels, a two-by-two
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) square of the image. For example, Cr\ :sub:`0` belongs to Y'\ :sub:`00`,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) Y'\ :sub:`01`, Y'\ :sub:`10`, and Y'\ :sub:`11`. Following the Cr plane
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) is the Cb plane, just like the Cr plane. ``V4L2_PIX_FMT_YUV420`` is the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) same except the Cb plane comes first, then the Cr plane.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) If the Y plane has pad bytes after each row, then the Cr and Cb planes
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) have half as many pad bytes after their rows. In other words, two Cx
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) rows (including padding) is exactly as long as one Y row (including
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) padding).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) **Byte Order.**
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) Each cell is one byte.
