^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) ===========
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) These are two-plane versions of the YUV 4:2:0 format. The three
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) components are separated into two sub-images or planes. The Y plane is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_NV12``, a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) combined CbCr plane immediately follows the Y plane in memory. The CbCr
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) plane is the same width, in bytes, as the Y plane (and of the image),
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) but is half as tall in pixels. Each CbCr pair belongs to four pixels.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) For example, Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) Y'\ :sub:`01`, Y'\ :sub:`10`, Y'\ :sub:`11`. ``V4L2_PIX_FMT_NV21`` is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) the same except the Cb and Cr bytes are swapped, the CrCb plane starts
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) with a Cr byte.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) If the Y plane has pad bytes after each row, then the CbCr plane has as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) many pad bytes after its rows.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) **Byte Order.**
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) Each cell is one byte.
