\qmltype MediaPlayer \instantiates QMediaPlayer

Adds media playback to a scene.

\inqmlmodule QtMultimedia

\qml Text { text: "Click Me!"; font.pointSize: 24; width: 150; height: 50;

MediaPlayer { id: playMusic source: "music.wav" audioOutput: AudioOutput {} } MouseArea { anchors.fill: parent onPressed: { playMusic.play() } } } \endqml

You can use MediaPlayer together with a MultiMedia::AudioOutput to play audio content, or you can use it in conjunction with a Multimedia::VideoOutput for rendering video.

\qml Item { MediaPlayer { id: mediaplayer source: "groovy_video.mp4" audioOutput: AudioOutput {} videoOutput: videoOutput }

VideoOutput { id: videoOutput anchors.fill: parent }

MouseArea { anchors.fill: parent onPressed: mediaplayer.play(); } } \endqml
