title: MLT framework windows build melt failed to load avformat
body: <p>I build mlt framework on windows following the official guide <a href="http://www.mltframework.org/bin/view/MLT/WindowsBuild" rel="nofollow noreferrer">http://www.mltframework.org/bin/view/MLT/WindowsBuild</a> and the solution of <a href="https://stackoverflow.com/questions/29460171/error-building-mlt-framework-on-windows/29472194#29472194">Error building MLT framework on Windows</a> for the errors.</p>
  
  <p>But when I call the command <code>melt</code> it doesn't work correctly. (<code>melt noise</code> does work)</p>
  
  <p>Using <code>melt -query "video_codecs"</code> I get <code># No video codecs - failed to load avformat consumer</code>.</p>
  
  <p>So it cannot load ffmpeg. Is there a problem with the compilation or is something related to Windows?</p>
