title: Can't encode video with Xuggler
body: <p>I'm trying to create simple application with Xuggler, which has to encode sequence of pictures into video.
  I've installed xuggler, as described in official site.
  Here is example of code (which I've actually found on Xuggler wiki site)</p>
  
  <pre><code>import java.awt.Color;
  import java.awt.Graphics2D;
  import java.awt.image.BufferedImage;
  
  import org.slf4j.Logger;
  import org.slf4j.LoggerFactory;
  
  import com.xuggle.mediatool.IMediaViewer;
  import com.xuggle.mediatool.IMediaWriter;
  import com.xuggle.mediatool.ToolFactory;
  import com.xuggle.xuggler.ICodec;
  
  import static com.xuggle.xuggler.Global.DEFAULT_TIME_UNIT;
  import static java.util.concurrent.TimeUnit.SECONDS;
  import static java.util.concurrent.TimeUnit.MILLISECONDS;
  
  
  public class Test {
  
      private static final Logger log = LoggerFactory.getLogger(Test.class);
      {
          log.trace("&lt;init&gt;");
      }
  
      public static void main(String[] args) {
  
          final long duration = DEFAULT_TIME_UNIT.convert( 3, SECONDS );
  
          final int videoStreamIndex = 0;
          final int videoStreamId = 0;
          final long frameRate = DEFAULT_TIME_UNIT.convert(15, MILLISECONDS);
          final int width = 320;
          final int height = 200;
  
          long nextFrameTime = 0;
  
          final IMediaWriter writer = ToolFactory.makeWriter("/out.mov");
  
          writer.addVideoStream(videoStreamIndex, videoStreamId, 
                        width, height);
  
          while ( nextFrameTime &lt; duration )
              {
                  BufferedImage frame = new BufferedImage( 320, 200, BufferedImage.TYPE_INT_RGB );
                  Graphics2D gr = (Graphics2D) frame.getGraphics();
                  gr.setColor(Color.RED);
                  gr.drawLine(0, 0, 200, 200);
                  writer.encodeVideo(videoStreamIndex, frame, nextFrameTime, 
                         DEFAULT_TIME_UNIT);
                  nextFrameTime += frameRate;
              }
  
          writer.close();
  
      }
  
  }
  </code></pre>
  
  <p>After launching, I've got exception:</p>
  
  <pre><code>Exception in thread "main" java.lang.UnsupportedOperationException: No converter "null" found.

  </code></pre>
  
  <p>Could you advise me something to solve this problem?
  Thanks</p>
