<h2>Detailed Description</h2>
<p>The QMetaDataWriterControl class provides write access to the meta-data of a <a href="qmediaservice.html">QMediaService</a>'s media.</p>
<p>If a <a href="qmediaservice.html">QMediaService</a> can provide write access to the meta-data of its current media it will implement QMetaDataWriterControl. This control provides functions for both retrieving and setting meta-data values. Meta-data may be addressed by the keys defined in the <a href="qmediametadata.html">QMediaMetaData</a> namespace.</p>
<p>The functionality provided by this control is exposed to application code by the meta-data members of <a href="qmediaobject.html">QMediaObject</a>, and so meta-data access is potentially available in any of the media object classes. Any media service may implement QMetaDataControl.</p>
<p>The interface name of QMetaDataWriterControl is <tt>org.qt-project.qt.metadatawritercontrol/5.0</tt> as defined in <a href="qmetadatawritercontrol.html#QMetaDataWriterControl_iid">QMetaDataWriterControl_iid</a>.</p>
