title: How to use the Video widget in Kivy?
body: <p>I'm using Kivy's <a href="http://kivy.org/docs/api-kivy.uix.video.html" rel="nofollow">Video</a> widget to display a certain video file. I'm on <code>Windows 8 x64</code>. Here's the video-related entries from the start log:</p>
  
  <pre><code>[DEBUG             ] [Video       ] Ignored &lt;ffmpeg&gt; (import error)
  [DEBUG             ] [Video       ] Ignored &lt;pyglet&gt; (import error)
  [INFO              ] [Video       ] Provider: null(['video_ffmpeg', 'video_pyglet'] ignored)
  </code></pre>
  
  <p>The output shows a white square in place of the video. The thing is that Kivy doesn't seem to care about the video at all. Even if I use a non-existing <code>source</code> argument it doesn't complain.</p>
  
  <p>I'm using Kivy 1.8.0 and Python 3.4.1.</p>
