<h2>Detailed Description</h2>
<p>The QMediaPlayerControl class provides access to the media playing functionality of a <a href="qmediaservice.html">QMediaService</a>.</p>
<p>If a <a href="qmediaservice.html">QMediaService</a> can play media is will implement QMediaPlayerControl. This control provides a means to set the <a href="qmediaplayercontrol.html#setMedia">media</a> to play, <a href="qmediaplayercontrol.html#play">start</a>, <a href="qmediaplayercontrol.html#pause">pause</a> and <a href="qmediaplayercontrol.html#stop">stop</a> playback, <a href="qmediaplayercontrol.html#setPosition">seek</a>, and control the <a href="qmediaplayercontrol.html#setVolume">volume</a>. It also provides feedback on the <a href="qmediaplayercontrol.html#duration">duration</a> of the media, the current <a href="qmediaplayercontrol.html#position">position</a>, and <a href="qmediaplayercontrol.html#bufferStatus">buffering</a> progress.</p>
<p>The functionality provided by this control is exposed to application code through the <a href="qmediaplayer.html">QMediaPlayer</a> class.</p>
<p>The interface name of QMediaPlayerControl is <tt>com.nokia.Qt.QMediaPlayerControl/1.0</tt> as defined in <a href="qmediaplayercontrol.html#QMediaPlayerControl_iid">QMediaPlayerControl_iid</a>.</p>
