From ba72e4202f1958028c9b40cd858fdfb46508335b Mon Sep 17 00:00:00 2001 From: Han-Lin Chen via libcamera-devel Date: Fri, 12 Aug 2022 17:01:03 +0800 Subject: libcamera: ipu3: Use std::max() instead of expandTo() to get the max resolution Using Size::expandTo() to find the max resolution might generate a non-existent resolution. For example, when application request streams for 1920x1080 and 1600x1200, the max resolution will be wrongly 1920x1200 and fails the configuration.
