11 | V4L2_PIX_FMT_YVU444M | |
12 | Planar formats with full horizontal resolution, also known as YUV and | |
13 | YVU 4:4:4 | |
14 | ||
15 | ||
16 | Description | |
17 | =========== | |
18 | ||
19 | This is a multi-planar format, as opposed to a packed format. The three | |
20 | components are separated into three sub-images or planes. | |
21 | ||
22 | The Y plane is first. The Y plane has one byte per pixel. For | |
23 | ``V4L2_PIX_FMT_YUV444M`` the Cb data constitutes the second plane which | |
24 | is the same width and height as the Y plane (and as the image). The Cr | |
25 | data, just like the Cb plane, is in the third plane. | |
26 | ||
27 | ``V4L2_PIX_FMT_YVU444M`` is the same except the Cr data is stored in the | |
28 | second plane and the Cb data in the third plane. | |
29 | ||
30 | If the Y plane has pad bytes after each row, then the Cb and Cr planes | |
31 | have the same number of pad bytes after their rows. | |
32 | ||
33 | ``V4L2_PIX_FMT_YUV444M`` and ``V4L2_PIX_FMT_YUV444M`` are intended to be | |
34 | used only in drivers and applications that support the multi-planar API, | |
35 | described in :ref:`planar-apis`. | |

38 | Each cell is one byte. |
