2024-02-27utils: rkisp1: gen-csc-table.py: Don't presume python3 locationLaurent Pinchart
The python3 binary may be present in a location other than /usr/bin/. Use /usr/bin/env to locate it. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Daniel Scally <dan.scally@ideasonboard.com>
2022-09-30utils: rkisp1: gen-csc-table: Add support for inverting the CSCLaurent Pinchart
Add a -i/--invert command line argument to invert the YCbCr encoding and output a YCbCr to RGB matrix. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2022-08-30utils: rkisp1: gen-csc-table: Specify coefficients with full precisionLaurent Pinchart
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.

2022-08-26utils: rkisp1: Add script to generate CSC coefficientsLaurent Pinchart
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.

2022-07-15utils: rkisp1: Support optional CSI-2 receiver subdevLaurent Pinchart
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. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com>
2022-07-15utils: rkisp1: Fix sensor format parsingLaurent Pinchart
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. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com>
2022-07-15utils: rkisp1: Remove frames before starting captureLaurent Pinchart
Delete frames previously captured before starting a new capture, to avoid mixing old and new frames. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com>

2020-02-13utils: rkisp1: sync topology with upstream driver in capture scriptHelen Koike
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.

2019-03-29utils: rkisp1: Add test capture scriptLaurent Pinchart
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. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
