title: Looking for workaround on streaming NotOptimized M4A files iOS
body: <p>I'm trying use <strong>AudioFileStream service</strong> and <strong>Audio Unit</strong> to streaming &amp; play <strong>NotOptimized M4A</strong> files(the header is not at the beginning of the file) and I tried "StreamingKit", "FreeStreamer" and so on. none of them support it.</p>
  
  <blockquote>
    <p>err = AudioFileStreamParseBytes(self.audioFileStreamID, length, data, 0);</p>
  </blockquote>
  
  <p>above returns (kAudioFileStreamError_NotOptimized)</p>
  
  <p>I understand it. but is there a way to handle it? I googled a lot, only I got is "Overcast" did it.
