title: Matlab: loading wmv video files
body: <p>I am trying to load a wmv video in Matlab as follows:</p>
  
  <pre><code>vidObj = mmreader('video.wmv');
  </code></pre>
  
  <p>However, I receive the following error:</p>
  
  <pre><code>The file requires the following codec(s) to be installed on your system: video/x-ms-asf
  </code></pre>
  
  <p>I don't understand why I am receiving this error, since I am able to play wmv files on my system. I am running Matlab 7.10.0 (R2010a) on Ubuntu 11.04. How can I fix this problem?</p>
