 134
 135 wx.MediaCtrl is a class that allows a way to convieniently display
 136 various types of media, such as videos, audio files, natively through
 137 native codecs.  Several different formats of audio and video files are
 138 supported, but some formats may not be playable on all platforms or
 139 may require specific codecs to be installed.
 140
 141 <p>
 142 wx.MediaCtrl uses native backends to render media, for example on Windows
 143 there is a ActiveMovie/DirectShow backend, and on Macintosh there is a
 144 QuickTime backend.
 145 <p>
 146 wx.MediaCtrl is not currently available on unix systems.
