title: Increase the bitrate tolerance of ffmpeg for creating screenshots of a movie
body: <p>I'm getting the error <code>bitrate tolerance too small for bitrate</code> so far no problem. I know that there are several switches to increase that but nothing works.</p>
  
  <pre><code>ffmpeg -y -r 1/30 -b:v 999999k -bt 999999k -maxrate 999999k -i in.flv out%03d.jpg
  </code></pre>
  
  <p>The source of that commandline is <a href="http://ffmpeg.org/trac/ffmpeg/wiki/Create%20a%20thumbnail%20image%20every%20X%20seconds%20of%20the%20video" rel="nofollow">directly from ffmpeg</a>. But that crashes:</p>

  <p>Some ideas what I'm doing wrong?</p>
