[libcamera-devel] [PATCH 0/2] Application support for per-mode sensitivities

[David Plowman]

Hi everyone

Here's that potentially "missing piece" of support for per-mode
sensitivities. The question was how an application could get hold of
the selected mode's sensitivity before starting the camera, and
solution implemented here returns it in the CameraConfiguration
object.

There are two patches, and they would need to be applied on top of the
first set of "per-mode sensitivities" patches.

1. The first patch merely adds a modeSensitivity field to the
CameraConfiguration and documents it.

2. The second patch returns the correct value from the Raspberry Pi
pipeline handler. I note that if CamHelpers move out of the IPA and
over to the pipeline handler, then this could become rather simpler.

Thanks in advance for any feedback.

Best regards
David
