`V4L2_PIX_FMT_NV24`

`V4L2_PIX_FMT_NV42`

Formats with full horizontal and vertical chroma resolutions, also known as YUV 4:4:4. One luminance and one chrominance plane with alternating chroma samples as opposed to `V4L2_PIX_FMT_YVU420`

## Description

These are two-plane versions of the YUV 4:4:4 format. The three components are separated into two sub-images or planes. The Y plane is first, with each Y sample stored in one byte per pixel. For `V4L2_PIX_FMT_NV24`, a combined CbCr plane immediately follows the Y plane in memory. The CbCr plane has the same width and height, in pixels, as the Y plane (and the image). Each line contains one CbCr pair per pixel, with each Cb and Cr sample stored in one byte. `V4L2_PIX_FMT_NV42` is the same except that the Cb and Cr samples are swapped, the CrCb plane starts with a Cr sample.

If the Y plane has pad bytes after each row, then the CbCr plane has twice as many pad bytes after its rows.
