New description:

 Summary of the bug:
 Concatenating nellymoser encoded audio streams to .mp3 usually works when
 setting input codecs via "-acodex nellymoser". In some instances however
 it fails:

 Stream specifier ':3' in filtergraph description [0:0][0:2][0:3]
 concat=n=3:v=0:a=1 matches no streams.

 When setting input codecs individually via "-codec:a:0 nellymoser
 -codec:a:1 nellymoser .." there is no problem.

 How to reproduce:
 ffmpeg -acodec nellymoser -i

Comment:

 Needs `-analyzeduration 75M`.
 Much more important: Do you know where this file comes from?

 For future tickets: Please test current FFmpeg git head, the only version
 supported here and always provide the command line you tested together
 with the complete, uncut console output.
