title: Matplotlib-Animation "No MovieWriters Available"
body: <p>Under Linux, I've been checking out matplotlib's animation class, and it seems to work except that I cant initialise the movie writer to write out the movie.</p>
  
  <p>Using either of the examples:</p>
  
  <ul>
  <li><a href="http://matplotlib.org/examples/animation/moviewriter.html">http://matplotlib.org/examples/animation/moviewriter.html</a></li>
  <li><a href="http://matplotlib.org/examples/animation/basic_example_writer.html">http://matplotlib.org/examples/animation/basic_example_writer.html</a></li>
  </ul>
  
  <p>results in the error "<strong>RuntimeError: No MovieWriters available!</strong>"</p>
  
  <p>Im using matplotlib version 1.3.x and have installed (hopefully) all the codecs.</p>
  
  <p>Can someone please suggest as to why I get this error? If its a codecs issue, which codecs (+versions) should I install?
  If its something else that's broken, is there an alternative for creating animations in python?</p>
