Detailed DescriptionThe QVideoWidget class provides a widget which presents video produced by a media object. 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;
videoWidget = new QVideoWidget;
player->setVideoOutput(videoWidget);
player->setMedia(QUrl("http://example.com/movie.mp4"));
videoWidget->show();
player->play();
Note: Only a single display output can be attached to a media object at one time. See also QMediaObject, QMediaPlayer, and QGraphicsVideoItem. Property Documentation
