Since 2017, there is an space reserved for userspace API,
created by changeset 1d596dee38 ("docs: Create a user-space API guide").
As the media subsystem was one of the first subsystems to use
Sphinx, until this patch, we were keeping things on a separate
place.
Let's just use the new location, as having all uAPI altogether
will likely make things easier for developers.

14-bit packed Bayer formats
|
|
|
|
|
|
Description
|
|
===========
|
|
|
|
These four pixel formats are packed raw sRGB / Bayer formats with 14
|
|
bits per colour. Every four consecutive samples are packed into seven
|
|
bytes. Each of the first four bytes contain the eight high order bits
|
|
of the pixels, and the three following bytes contains the six least
|
|
significants bits of each pixel, in the same order.
|
|
|
|
Each n-pixel row contains n/2 green samples and n/2 blue or red samples,
|
|
with alternating green-red and green-blue rows. They are conventionally
|
|
described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example
|
|
of one of these formats:
|
|
|
|
**Byte Order.**
|
|
Each cell is one byte.
