| Planar formats with ¼ horizontal and vertical chroma resolution, also |
| 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_YVU410``, |
| the Cr plane immediately follows the Y plane in memory. The Cr plane is |
| ¼ the width and ¼ the height of the Y plane (and of the image). Each Cr |
| belongs to 16 pixels, a four-by-four square of the image. Following the |
| Cr plane is the Cb plane, just like the Cr plane. |
| ``V4L2_PIX_FMT_YUV410`` is the same, except the Cb plane comes first, |
| If the Y plane has pad bytes after each row, then the Cr and Cb planes |
| have ¼ as many pad bytes after their rows. In other words, four Cx rows |
| (including padding) are exactly as long as one Y row (including |
