title: FFmpeg '-bframebias' option gone?
body: <p>Recently I updated ffmpeg to version 1.1, when I run a command containing <code>bframebias</code>, it showed an error: </p>
  
  <pre><code>Unrecognized option 'bframebias'.
  Error splitting the argument list: Option not found
  </code></pre>
  
  <p>This command used to work fine. So the option <code>bframebias</code> is removed or it is replaced by another option?</p>
