[FFmpeg-user] -f segment does not seem to be working

[Michael Hipp]

I'm attempting to segment an incoming mp3 audio stream:

ffmpeg -i udp://239.8.8.8:5000 -acodec copy -f segment -segment_time 5 out%03d.mp3

The audio records fine but it never segments. The one file (out000.mp3) just 
grows and grows.

What am I doing wrong?

I'm using ffpmeg as ships with ubuntu 12.04 (version 
0.8.10-4:0.8.10-0ubuntu0.12.04.1).

Thanks,
Michael
