From 299e5278bd7657c785b7adac0c4f02d7e42f22c2 Mon Sep 17 00:00:00 2001 From: Naushir Patuck Date: Fri, 26 Apr 2024 12:18:15 +0100 Subject: ipa: rpi: Fix for incorrectly reported max shutter speed The maximum shutter speed calculation in the cam-helper relied on the frame duration limits being correctly set in the cam-helper's mode structure. This was not the case on first startup, so the maximum shutter speed reported back via the ControlInfo was incorrect. Fix this by setting up the camera mode in the cam-helper before querying for the max shutter value.
