<p>Qt Multimedia is an essential module that provides a rich set of QML types and C++ classes to handle multimedia content. It also provides necessary APIs to access the camera and radio functionality. The included <a href="qtaudioengine-qmlmodule.html">Qt Audio Engine</a> provides types for 3D positional audio playback and content management.</p>
<p>The functionality of this module is divided into the following submodules:</p>
<div class="table"><table class="generic">
<tr valign="top" class="odd"><td ><a href="qtmultimedia-module.html">Qt Multimedia</a></td><td >Provides API for multimedia-specific use cases.</td></tr>
<tr valign="top" class="even"><td ><a href="qtmultimediawidgets-module.html">Qt Multimedia Widgets</a></td><td >Provides the widget-based multimedia API.</td></tr>
</table></div>
<a name="getting-started"></a>
<h2 id="getting-started">Getting Started</h2>
<p>The QML types can be imported into your applciation using the following import statement in your <code>.qml</code> file.</p>
<pre class="qml">
</pre>
<p>If you intend to use the C++ classes in your application, include the C++ definitions using the following directive:</p>
<pre class="cpp">
<span class="preprocessor">#include <QtMultimedia></span>
<span class="preprocessor">#include <QtMultimediaWidgets></span>
</pre>
<p><b>Note: </b>If you are using a few classes from this module, we recommend including those specific classes only instead of the module.</p><p>To link against the corresponding C++ libraries, add the following to your <code>qmake</code> project file:</p>
<pre class="cpp">
QT <span class="operator">+</span><span class="operator">=</span> multimedia multimediawidgets
