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
incorrect. Fix it.

With sensors supporting crop, the regexp used to parse the media-ctl
output isn't correct as the pad configuration may span multiple lines
and contain other parameters. Fix it.

Delete frames previously captured before starting a new capture, to
avoid mixing old and new frames.

Link between resizer and capture is immutable and doesn't need to be

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.
