<h2>Detailed Description</h2>
<p>The QGraphicsVideoItem class provides a graphics item which display video produced by a <a href="qmediaobject.html">QMediaObject</a>.</p>
<p>Attaching a QGraphicsVideoItem to a <a href="qmediaobject.html">QMediaObject</a> 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 <a href="qmediaobject.html">QMediaObject</a> to the <a href="qmediabindableinterface.html#setMediaObject">setMediaObject</a>() function.</p>
