Since 2017, there is an space reserved for userspace API,
created by changeset 1d596dee3862 ("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 Bayer formats expanded to 16 bits
|
|
|
|
|
|
Description
|
|
===========
|
|
|
|
These four pixel formats are raw sRGB / Bayer formats with 14 bits per
|
|
colour. Each sample is stored in a 16-bit word, with two unused high
|
|
bits filled with zeros. Each n-pixel row contains n/2 green samples
|
|
and n/2 blue or red samples, with alternating red and blue rows. Bytes
|
|
are stored in memory in little endian order. They are conventionally
|
|
described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an
|
|
example of a small V4L2_PIX_FMT_SBGGR14 image:
|
|
|
|
**Byte Order.**
|
|
Each cell is one byte, the two most significant bits in the high bytes are
|
|
zero.
