It needs to be\nupdatable precisely when the auto modes are enabled.\n\nThe fix is to ignore the enabled/disabled status of AEC/AGC, matching\nour other controls (metering mode, constraint mode etc.). While there\nmight be a debate to be had about what the actual behaviour of all\nthese controls should be, for the time being we'll just match\neverything else.\n\nSigned-off-by: David Plowman <david.plowman@raspberrypi.com>\n---\n src/ipa/rpi/common/ipa_base.cpp | 7 -------\n 1 file changed, 7 deletions(-)", "diff": "diff --git a/src/ipa/rpi/common/ipa_base.cpp b/src/ipa/rpi/common/ipa_base.cpp\nindex 6448e6ab..8dfe35cc 100644\n--- a/src/ipa/rpi/common/ipa_base.cpp\n+++ b/src/ipa/rpi/common/ipa_base.cpp\n@@ -1026,13 +1026,6 @@ void IpaBase::applyControls(const ControlList &controls)\n \t\t\t\tbreak;\n \t\t\t}\n \n-\t\t\t/*\n-\t\t\t * Ignore AE_EXPOSURE_MODE if the shutter or the gain\n-\t\t\t * are in auto mode.\n-\t\t\t */\n-\t\t\tif (agc->autoExposureEnabled() || agc->autoGainEnabled())\n-\t\t\t\tbreak;\n-\n \t\t\tint32_t idx = ctrl.second.get<int32_t>();\n \t\t\tif (ExposureModeTable.count(idx)) {\n \t\t\t\tagc->setExposureMode(ExposureModeTable.at(idx));\n", "prefixes": [] }
