    }

}

when trying to check the recorderStatus it is 0 according to documentation .

Value Description

UnavailableStatus 0 Recording is not supported by the camera.

UnloadedStatus 1 The recorder is available but not loaded. . . .

is there something wrong with the code or qml recording support is limited ?

Answer 1

According to Qt 5.5 documentation video recording is currently not supported for windows: http://doc.qt.io/qt-5/qtmultimedia-windows.html
