 Summary of the bug:

 When attempting to convert from AVC encoded .mp4  with .mp3 audio stream I
 am getting the error

 Error while decoding stream #0:1: Invalid data found when processing input
 [mp3 @ 00000000057ffaa0] Header missing

 If I map out the mp3 stream it encodes fine.

 File was encoded using handbrake and is usable in all other apps including
 some trasnscoding dlna servers

 How to reproduce:
