From ff291b3c15ba250fb05236a774771fdf54554ff7 Mon Sep 17 00:00:00 2001 From: David Plowman Date: Thu, 18 Jun 2020 12:12:35 +0100 Subject: libcamera: ipa: raspberrypi: Allow SwitchMode method to return camera settings This commit adds a Metadata parameter to the SwitchMode method enabling it to return camera and other settings to the caller (usually the configure method, just after the camera mode has been selected). In future this will allow the Raspberry Pi IPAs to take those settings (such as exposure and analogue gain) and program them directly into the camera or ISP before the camera is even started.
