One ask that may not be captured anywhere: currently, it is impossible to have a QML Camera and not start it. If I could request, 1. a way to probe hardware without activating it 2. a way to have a QML Camera without getting frames from it, that is to set `active: false` is the default. Currently, there is not even active property. We have to do a Component.onCompleted: stop() which has already triggered the permission dialog. This was ok in the past, but the trend and proper usage is to request permission only when it is needed. _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
