-V4L2_PIX_FMT_YUV420
-Planar formats with ½ horizontal and vertical chroma resolution, also
-known as YUV 4:2:0
-
-
-Description
-===========
-
-These are planar formats, as opposed to a packed format. 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_YVU420``, the Cr plane immediately follows the Y plane in
-memory. The Cr plane is half the width and half the height of the Y
-plane (and of the image). Each Cr belongs to four pixels, a two-by-two
-square of the image. For example, Cr\ :sub:`0` belongs to Y'\ :sub:`00`,
-Y'\ :sub:`01`, Y'\ :sub:`10`, and Y'\ :sub:`11`. Following the Cr plane
-is the Cb plane, just like the Cr plane. ``V4L2_PIX_FMT_YUV420`` is the
-same except the Cb plane comes first, then the Cr plane.
-
-If the Y plane has pad bytes after each row, then the Cr and Cb planes
-have half as many pad bytes after their rows. In other words, two Cx
-rows (including padding) is exactly as long as one Y row (including
-padding).
-
-**Byte Order.**
-Each cell is one byte.
