[libcamera-devel,00/12] android: Exposure times + scaler crop + android metadata

10814 mbox series

Based on:
[PATCH v5 00/10] libcamera: camera_sensor: Make validation more strict

This series addresses mainly 3 things, in order to grow the Camera HAL by
instrumenting the IPU3 pipeline handler to provide the required information.

- Patches [1/12] -> [5/12]
  Register the ExposureTime control in the IPU3 pipeline handler
  to be able to register the EXPOSURE_TIME_RANGE static metadata in the HAL.
  Reports the default exposure time and collects it as EXPOSURE_TIME dynamic
  metadata in the Camera HAL.

-Patches [5/12] -> [10/12]
  Register the ScalerCropMaximum property and handle the ScalerCrop
  property in the IPU3 pipeline handler to be able to register
  the MAX_DIGITAL_ZOOM static metadata and to handle the SCALER_CROP_REGION
  control and dynamic metadata.

- Patches [11/12] and [12/12]
  Fixes for the android.hardware.camera2.cts.CaptureRequestTest CTS test
  module. The last patch specifically adds in bulk a lot of dynamic metadata
  which we didn't report. As reported in the commit message, handling
  MAX_FRAME_DURATION would fix all tests in that module (2 on 22 failing with
  this series applied).

As a bonus, it is not possible to switch between the front and the back camera
in the stock ChromeOS camera application.

Thanks
