161wx.MediaCtrl is a class that allows a way to convieniently display
162various types of media, such as videos, audio files, natively through
163native codecs. Several different formats of audio and video files are
164supported, but some formats may not be playable on all platforms or
165may require specific codecs to be installed.

167<p>
168wx.MediaCtrl uses native backends to render media, for example on Windows
169there is a ActiveMovie/DirectShow backend, and on Macintosh there is a
170QuickTime backend.
171<p>
172wx.MediaCtrl is not currently available on unix systems.
