 '''Summary of the bug:'''
 I´ve captured some AAC LATM streams that are being broadcasted (DVB-T)
 here in Brazil and tried to transcode them using FFmpeg. The stereo
 streams work fine but the 5.1 streams are generating some error messages
 during transcode.

 Besides that, the resulting file is always a little smaller in duration
 than the original (when there´s music, you can more easily notice that the
 resulting audio seems to be playing "faster", due to missed samples I
 guess).

 I´ve found some old tickets related to AAC streams (ticket:1694 and
 ticket:2335) with similar error messages, and testing the samples provided
 there also got me the same behaviour.

 '''How to reproduce:'''
 {{{
 % ffmpeg -report -v 9 -loglevel 99 -i
 problem_transcoding_5dot1_aac_latm_audio.aac out.wav
 ffmpeg version N-71959-g9253cc4
 built on 2015-05-07
 }}}

 I have uploaded the '''problem_transcoding_5dot1_aac_latm_audio.aac'''
 file to the "incoming" folder of the FTP. I´ve also uploaded the complete
 report generated by FFmpeg under the name
 '''problem_transcoding_5dot1_aac_latm_audio.log'''.

 Here´s is part of the full report:
