See the mailing list and issue tracker on https://sr.ht/~martijnbraam/Megapixels/
Megapixels checks multiple locations for it's configuration file and uses the first one it finds. As first step it will get the first compatible name in the device tree, in the case of a PinePhone this might be "pine64,pinephone-1.2". Then that dtname will be used as the filename in the search path in this order:
The files in /usr/share/megapixels should be the config files distributed in this repository. The other locations allow the user or distribution to override config.
Config file format
Configuration files are INI format files.
This provides global info, currently only the
csi key exists, telling megapixels which device in the
media-ctl tree is the interface to the kernel. This should provide the /dev/video* node.
[rear] and [front]
These are the sections describing the sensors.
driver=ov5640the name of the media node that provides the sensor and it's /dev/v4l-subdev* node.
height=480the resolution to use for the sensor
rate=15the refresh rate in fps to use for the sensor
fmt=BGGR8sets the pixel and bus formats used when capturing from the sensor, only BGGR8 is fully supported
rotate=90the rotation angle to make the sensor match the screen
