Source files in libcamera start by a comment block header, which
includes the file name and a one-line description of the file contents.
While the latter is useful to get a quick overview of the file contents
at a glance, the former is mostly a source of inconvenience. The name in
the comments can easily get out of sync with the file name when files
are renamed, and copy & paste during development have often lead to
incorrect names being used to start with.
Readers of the source code are expected to know which file they're
looking it. Drop the file name from the header comment blocks in all
remaining locations that were not caught by the automated script as they
are out of sync with the file name.

The python3 binary may be present in a location other than /usr/bin/.
Use /usr/bin/env to locate it.

Add a -i/--invert command line argument to invert the YCbCr encoding and
output a YCbCr to RGB matrix.

The Rec01, Rec709, Rec2020 and SMTPE 240M standards specify the Cb and
Cr coefficients of the RGB to Y'CbCr conversion matrix using a quotient
of two values. Use the exact same formulas instead of hardcoding the
division results with a lower precision.

This script generates fixed-point integer coefficients for the YCbCr
encoding 3x3 matrix. The encoding, quantization and fixed-point
precision can be selected through command line arguments.
The main purpose of the script is to generate coefficient tables to
extend the rkisp1 driver with support for additional YCbCr encodings,
but it may be useful for other purposes as well given that the rounding
isn't trivial.
The Rec. 601 full and limited range coefficients have been verified to
match the values currently used by the rkisp1 driver.

The media graph may include a CSI-2 receiver entity between the sensor
and the ISP for platforms that have a CSI-2 receiver external to the
ISP. Support this by configuring the pipeline accordingly.

The regexp to convert the raw pixel media bus code to a pixel format is

With sensors supporting crop, the regexp used to parse the media-ctl
output isn't correct as the pad configuration may span multiple lines

rkisp1 kernel driver was merged upstream with minor changes in the
topology from the original driver libcamera based it's first support to
rkisp1.
Adapt libcamera capture script to work with upstream driver.
* Remove subdevice dphy from the pipeline.
* Add resizer in the pipeline.
* Fix links.
* Update entity names.

The script captures raw or processed frames from cameras based on the
Rockchip ISP1. It takes the sensor name as an argument and isn't meant
to depend on a particular platform.
