Detailed Description

Attaching a QGraphicsVideoItem to a QMediaObject allows it to display the video or image output of that media object. A QGraphicsVideoItem is attached to a media object by passing a pointer to the QMediaObject to the setMediaObject() method.

Only a single display output can be attached to a media object at one time.

player = new QMediaPlayer(this);
player->setVideoOutput(item);
graphicsView->scene()->addItem(item);
graphicsView->show();
player->setMedia(QUrl("http://example.com/myclip.ogv"));
player->play();
