Detailed Description¶

Attaching a QVideoWidget to a QMediaObject allows it to display the video or image output of that media object. A QVideoWidget is attached to media object by passing a pointer to the QMediaObject in its constructor, and detached by destroying the QVideoWidget .
player = new QMediaPlayer;

playlist = new QMediaPlaylist(player);
playlist->addMedia(QUrl("http://example.com/myclip1.mp4"));
playlist->addMedia(QUrl("http://example.com/myclip2.mp4"));

videoWidget = new QVideoWidget;
player->setVideoOutput(videoWidget);

videoWidget->show();
playlist->setCurrentIndex(1);
player->play();
Note : Only a single display output can be attached to a media object at one time.
