+wx.MediaCtrl is a class that allows a way to convieniently display
+various types of media, such as videos, audio files, natively through
+native codecs. Several different formats of audio and video files are
+supported, but some formats may not be playable on all platforms or
+may require specific codecs to be installed.
<p>
wx.MediaCtrl uses native backends to render media, for example on Windows
