<div class="descr"> <a name="details"></a>
<p>Multimedia support in Qt is provided by the <a href="qtmultimedia-index.html">Qt Multimedia</a> module. The Qt Multimedia module provides a rich feature set that enables you to easily take advantage of a platform's multimedia capabilities such as media playback and the use of camera and radio devices.</p>
<a name="features"></a>
<h2 id="features">Features</h2>
<p>Here are some examples of what can be done with Qt Multimedia APIs:</p>
<ul>
<li>Access raw audio devices for input and output</li>
<li>Play low latency sound effects</li>
<li>Play media files in playlists (such as compressed audio or video files)</li>
<li>Record audio and compress it</li>
<li>Tune and listen to radio stations</li>
<li>Use a camera, including viewfinder, image capture, and movie recording</li>
<li>Play 3D positional audio with <a href="qtaudioengine-qmlmodule.html">Qt Audio Engine</a></li>
<li>Decode audio media files into memory for processing</li>
<li>Accessing video frames or audio buffers as they are played or recorded</li>
</ul>
<a name="multimedia-components"></a>
<h2 id="multimedia-components">Multimedia Components</h2>
<p>Qt's multimedia APIs are categorized into four main components. More information (including background information and class references) is available here:</p>
