[libcamera-devel,00/10] Introduce camera properties

2384 mbox series

Hello,
   this series introduces libcamera properties, generated re-using the
libcamera control generation infrastructure and defined in a dedicated
properties_ids.yaml file.

The series parses the camera properties reported by the Linux kernel through two
example read-only controls that report the camera location and mounting
orientation, collects them as libcamera properties in the CameraSensor class
and expose them from the Camera instance.

It finally replaces the hardcoded values for the ANDROID_SENSOR_ORIENTATION
and ANDROID_LENS_FACING android static metadata with values reported by the
Camera.

Thanks
   j
