title: Quicktime not playing a h264 aac encoded file - why?
body: <p>Quicktime says "This file isn't compatible with quicktime player" when I try to play an mp4 file.  </p>
  
  <p>The info shows the encoding as :
  H.264, AAC, QuickTime Text</p>
  
  <p>The file plays fine with VLC.
  I need this file in my iTunes library so that I can stream it, hence the importance of this question.</p>
  
  <p>Strange thing is I have other files with similar codes that QT can play fine.
  How can I check why this file is incompatible?</p>
  
  <p>Here is the log from ffprobe:</p>
