Detailed DescriptionThe 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. See also QMediaObject, QMediaPlayer, and QVideoWidget. Property Documentation
