@dhirvonen said in VideoOutput + QQuickView::SizeRootObjectToView + Qt::PortraitOrientation: @Charby Even better (and much cleaner). After inverting the -camera.orientation it works beautifully. Thanks again. VideoOutput { id: output source: camera objectName: "VideoOutput" filters: [ infofilter, videofilter ] anchors.fill: parent orientation: -camera.orientation } Hi Mr, I am having a similar project of yours, but do not understand the objectName property my VideoOutput does, is it because I use Qt5.15? objectName: "VideoOutput" Thanks!
