The QGraphicsVideoItem class provides a graphics item which display video produced by a QMediaObject.
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() function.
player = new QMediaPlayer(this); QGraphicsVideoItem *item = new QGraphicsVideoItem; player->setVideoOutput(item); graphicsView->scene()->addItem(item); graphicsView->show(); player->setMedia(video); player->play();
Note: Only a single display output can be attached to a media object at one time.
