[LAU] Slightly OT - MP3 encoding ffmpeg and lame

Hi All,

I'm trying to get ffmpeg to encode to mp3 format on a Centos 5.5 system.

I have an FC6 system with lame 3.97 and ffmpeg 0.4.9 and a FC8 system 
with lame 3.98 and ffmpeg 0.4.9 both installed from RPM's found at ATrpms.

On both FC6 and FC8 systems I can transcode a mpg file (captured by 
MythTV) to mp3 like this

  /usr/bin/ffmpeg -i /mnt/store/20560_20100621190000.mpg -ar 48000  
-acodec mp3 -ab 128k -f mp3 test.mp3

But with ffmpeg 0.4.9/0.5.2 and lame 3.97/3.98 from either ATrpms or 
RPMForge on Centos 5.5 I either get an error message about ffmpeg not 
recognising the mp3 codec or a floating point exception.

I must be missing something obvious, but what.

Would building either package from source be a better route?


Thanks in advance

Ken
