  </code></pre>
  
  <p>causes the following error:</p>

  The VideoReader plugin libmwgstreamerplugin failed to load properly.
  
  Error in VideoReader (line 172)
              obj.init(fileName);
  </code></pre>
  
  <p>I've installed gstreamer0.10 evidenced by:</p>
  
  <pre><code>alexander@alexander-desktop:~/Documents/MATLAB$ gst-
  gst-codec-info-0.10  gst-inspect-0.10     gst-visualise-0.10   
  gst-discoverer-0.10  gst-launch-0.10      gst-xmlinspect-0.10  
  gst-feedback-0.10    gst-typefind-0.10    gst-xmllaunch-0.10
  </code></pre>
  
  <p>I'm assuming I have the required plugins because of the following feedback:</p>
  
  <pre><code>alexander@alexander-desktop:~/Documents/MATLAB$ gst-inspect-0.10 | grep avi
  ogg:  oggaviparse: Ogg AVI parser
  typefindfunctions: video/x-msvideo: avi
  navigationtest:  navigationtest: Video navigation test
  avi:  avidemux: Avi demuxer
  avi:  avimux: Avi muxer
  avi:  avisubtitle: Avi subtitle parser
  </code></pre>
  
  <p>Can anybody help?</p>
