title: Post processing in ffmpeg to move 'moov atom' in MP4 files (qt-faststart)
body: <p>Is it possible to run ffmpeg from the command line which will either place the 'moov atom' metadata in the beginning of the MP4 file or run the qt-faststart as a post processing operation in ffmpeg so the generated file is stream-able through the internet?</p>
  
  <p>I can of course run it as a separate command, but would prefer it to be something</p>
  
  <ul>
  <li>as an option within ffmpeg, or </li>
  <li>as part of a post conversion, command line option when converting the video files via ffmpeg</li>
  </ul>

    <p>MOV / MP4 muxer</p>
    
    <p>The muxer options are:</p>
    
    <p>‘-moov_size bytes’</p>
  
  <pre><code>Reserves space for the moov atom at the beginning of the file instead of 
  placing the moov atom at the end. If the space reserved is insufficient, 
  muxing will fail.
