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

"http://example.com/myclip1.mp4"));
playlist->addMedia(
QUrl(
