161 wx.MediaCtrl is a class that allows a way to convieniently display
162 various types of media, such as videos, audio files, natively through
163 native codecs. Several different formats of audio and video files are
164 supported, but some formats may not be playable on all platforms or
165 may require specific codecs to be installed.
166
167 <p>
168 wx.MediaCtrl uses native backends to render media, for example on Windows
169 there is a ActiveMovie/DirectShow backend, and on Macintosh there is a
170 QuickTime backend.
171 <p>
172 wx.MediaCtrl is not currently available on unix systems.
