<h1>VideoPlayer Class Reference</h1>
<code>from PyKDE4.phonon import *</code>
<p>
Inherits: <a href="http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qwidget.html">QWidget</a> → <a href="http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qobject.html">QObject</a><br />
Namespace: Phonon.VideoPlayer<br />
<h2>Detailed Description</h2>
<p>\class VideoPlayer videoplayer.h Phonon/VideoPlayer
Playback class for simple tasks.
</p>
<p>
With %VideoPlayer you can get results quickly and easily. You can do the standard
playback tasks like play, pause and stop, but also set a playback volume and
seek (there's no guarantee that the seek will work, though).
</p>
<p>
Keep in mind that when the %VideoPlayer instance is deleted the playback will
stop.
</p>
<p>
A play and forget code example:
<pre class="fragment">
VideoPlayer *player = new VideoPlayer(parentWidget);
connect(player, SIGNAL(finished()), player, SLOT(deleteLater()));
player->play(url);
</pre>
