Description
Run this QML file:
import QtQuick 2.0 import QtMultimedia 5.0 import QtQuick.Controls 1.0 ApplicationWindow { width: 600 height: 600 visible: true Repeater { model: checkBox.checked ? 1 : 0 VideoOutput { anchors.centerIn: parent source: MediaPlayer { source: "video.mp4" autoPlay: true loops: MediaPlayer.Infinite } } } CheckBox { id: checkBox text: "enable player" } }
Press the checkBox several times to create/destroy MediaPlayer.
The application crashes with call stack:
