From 9b006872cde77c4982ebbcbc2e8ec83982dc32fe Mon Sep 17 00:00:00 2001 From: Paul Elder Date: Fri, 14 May 2021 18:25:47 +0900 Subject: android: camera_metadata: Add functions for instrumenting resizing Add utility functions to CameraMetadata to check if it has been resized, and for outputting the actual entry and data count. This is meant to be used to output information on resizing, to assist developers in choosing proper initial sizes to avoid resizing. Also make CameraDevice use these functions for static and result metadata.
