title: What audio formats does QAudioDecoder support?
body: <p>In the documentation <a href="http://doc.qt.io/qt-5/qaudiodecoder.html" rel="nofollow">QAudioDecoder</a> is mentioned to throw a <code>FormatError</code> when 'The format of a media resource isn't supported.' </p>
  
  <p>My question is what formats <strong>does</strong> <code>QAudioDecoder</code> support and could more formats be supported by users installing software such as LAME?</p>
