From d86746fc1739f678e4bafe43f5047cba9b6b053e Mon Sep 17 00:00:00 2001

Subject: [PATCH 01/21] libcamera: pipeline: simple: fix size adjustment in
validate()
SimpleCameraConfiguration::validate() adjusts the configuration of its
streams (if the size is not in the outputSizes) to the captureSize. But
the captureSize itself can be not in the outputSizes, and then the
adjusted configuration won't be valid resulting in camera configuration
failure.
