12 Planar formats with ¼ horizontal and vertical chroma resolution, also
19 These are planar formats, as opposed to a packed format. The three
20 components are separated into three sub-images or planes. The Y plane is
21 first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_YVU410``,
22 the Cr plane immediately follows the Y plane in memory. The Cr plane is
23 ¼ the width and ¼ the height of the Y plane (and of the image). Each Cr
24 belongs to 16 pixels, a four-by-four square of the image. Following the
25 Cr plane is the Cb plane, just like the Cr plane.
26 ``V4L2_PIX_FMT_YUV410`` is the same, except the Cb plane comes first,
29 If the Y plane has pad bytes after each row, then the Cr and Cb planes
30 have ¼ as many pad bytes after their rows. In other words, four Cx rows
31 (including padding) are exactly as long as one Y row (including
35 Each cell is one byte.
