title: Capture Windows screen with ffmpeg
body: <p>The <a href="http://www.ffmpeg.org" rel="noreferrer">ffmpeg</a> is cross-platform and very powerful software to handle video/audio or to stream it.
  On Linux ffmpeg can capture X11 screen with a command below:</p>
  
  <pre><code>ffmpeg -f x11grab -r 25 -s cif -i :0.0 out.mpeg
  </code></pre>
  
  <p>But is it possible to grab Windows Desktop with ffmpeg?</p>
