 105
 106 wx.MediaCtrl is a class that allows a way to convieniently display types of
 107 media, such as videos, audio files, natively through native codecs.
 108
 109 <p>
 110 wx.MediaCtrl uses native backends to render media, for example on Windows
 111 there is a ActiveMovie/DirectShow backend, and on Macintosh there is a
 112 QuickTime backend.
 113 <p>
 114 wx.MediaCtrl is not currently available on unix systems.
