 Summary of the bug:
 When trying to play back certain mp3 files, ffplay only plays silence and
 prints the messages:
 {{{
 [mp3 @ 0x7f0974000920] Format mp3 detected only with low score of 24,
 misdetection possible!
 [mjpeg @ 0x7f09740024e0] mjpeg: error, decode_app parser read over the end
 [mp3 @ 0x7f0974000920] Stream #0: not enough frames to estimate rate;
 consider increasing probesize
 [mp3 @ 0x7f0974000920] Stream #1: not enough frames to estimate rate;
 consider increasing probesize
 [mp3 @ 0x7f0974000920] Could not find codec parameters for stream 0
 (Audio: mp3, 0 channels, s16p): unspecified frame size
 Consider increasing the value for the 'analyzeduration' and 'probesize'
 options
 }}}
 And on these files, ffprobe does not report any bitrate or channels for
 the audio stream:
 {{{
   Duration: N/A, start: 0.000000, bitrate: N/A
     Stream #0:0: Audio: mp3, 0 channels, s16p
     Stream #0:1: Video: mjpeg, yuvj420p(pc), 160x160, 90k tbr, 90k tbn,
 90k tbc
 }}}
 The file plays fine with mpg123 and alsaplayer.

 How to reproduce:
 {{{
 % ffprobe Stuntin_\#39\;_By_The_floozies.mp3
 % ffplay Stuntin_\#39\;_By_The_floozies.mp3
 }}}
