ffmpeg segments only the first part of my audio file

问题

I'm implementing a http live streaming server to send audio file to iOS devices. No problem with Apple's tools, mediafilesegmenter, my files are valid and it works fine.

I'm trying now to segment the same file using ffmpeg. I've downloaded the last stable version which is the 0.10.2 for now.

Here is how I try to segment my mp3 file:

./ffmpeg -re -i input.mp3 -f segment -segment_time 10 -segment_list outputList.m3u8 -acodec libmp3lame -map 0 output%03d.mp3

It starts the mapping like expected but finish with only one .mp3 file.

Did I miss something in the process? Thanks in advance.

edit

Ok here is my latest command line:

ffmpeg -i input.mp3 -c:a libmp3lame -b:a 128k -map 0:0 -f segment -segment_time 10 -segment_list outputlist.m3u8 -segment_format mp3 'output%03d.mp3'

It still gives me only one file but the file is the hole song, not only one part. Here is the output of ffmpeg:

Audio only might be a bug. I contacted the FFMPEG player bug list, and a bug is filed: http://ffmpeg.org/trac/ffmpeg/ticket/1290
