# `V4L2_PIX_FMT_YUV444M`

# `V4L2_PIX_FMT_YVU444M`

Planar formats with full horizontal resolution, also known as YUV and YVU 4:4:4

## Description

This is a multi-planar format, 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_YUV444M` the Cb data constitutes the second plane which is the same width and height as the Y plane (and as the image). The Cr data, just like the Cb plane, is in the third plane.

`V4L2_PIX_FMT_YVU444M` is the same except the Cr data is stored in the second plane and the Cb data in the third plane.

If the Y plane has pad bytes after each row, then the Cb and Cr planes have the same number of pad bytes after their rows.

`V4L2_PIX_FMT_YUV444M` and `V4L2_PIX_FMT_YUV444M` are intended to be used only in drivers and applications that support the multi-planar API, described in .
