Description

I'm running FFmpeg 2.3.1 from the Arch Linux repository. There is an MP3 file that I am unable to play with mplayer, mpv, or ffplay and unable to convert or manipulate with ffmpeg. However, VLC and mpg123 play the file fine without complaining. This surprises me, since FFmpeg has a great track record with buggy/damaged media files. The file in question can be downloaded at http://tuutenn.s66.xrea.com/music/tuu_gekisinn.mp3 .

Output of ffplay:

$ ffplay tuu_gekisinn.mp3

The error occurs regardless of the values of analyzeduration and probesize. The output of ffmpeg -report -i tuu_gekisinn.mp3 is attached.

  • Component changed from undetermined to avformat
  • Keywords mpegts mp3 probe regression added
  • Priority changed from normal to important
  • Reproduced by developer set
  • Status changed from new to open
  • Version changed from 2.3 to git-master

Regression since 7ea39638 - related to ticket #580.
Attached cut sample produces different output but also no playback. The complete sample is in http://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket3844/

At least the first 19120 bytes of the sample are garbage.
