title: How to convert a FLV file recorded with Red5 / FMS to MP3?
body: <p>I'm looking for a way to extract the audio part of a FLV file. </p>
  
  <p>I'm recording from the user's microphone and the audio is encoded using the <a href="http://en.wikipedia.org/wiki/Nellymoser_Asao_Codec" rel="nofollow noreferrer">Nellymoser Asao Codec</a>. This is the default codec and there's no way to change this.</p>
