 This seems to affect primarily all flv files creates by
 OBS(https://obsproject.com/), but as it works fine with 2.8 and earlier
 versions, it's a regression in ffmpeg.

 How to reproduce:
 {{{
 % ./ffprobe ~/Downloads/test.flv
 ffprobe version N-75430-g0cfdaf4 Copyright (c) 2007-2015 the FFmpeg

 options

 }}}

 Increasing analyzeduation/probesize does not make any difference.

 Sample is attached, and i'm going through a bisect right now, will report
 back when done.
