The documentation of the MediaPlayer QML component lists the following properties:

• autoPlay
• autoLoad
• loops
• volume
• muted

However, those seem to be missing from the implementation (especially when looking at QMediaPlayer):

qrc:/main.qml:16:9: Cannot assign to non-existent property "autoPlay"

I understand that some of them have been moved to AudioOutput (volume, muted) but this is not reflected in the documentation.
