FFMPEG mp3

[ontop]

I encountered a problem when trying to convert uncompressed avi to divx with ffmpeg. Ffmpeg doesn't allow mp3 encoding although "GUI" pocketdivxencoder makes it possible. (Se settings below).

Anyone know why?

I had a look at the pocketdivxencoder site and it uses mencoder and not ffmpeg. That aside, did you compile ffmpeg with mp3 enabled? i.e. --enable-mp3lame

If you didn't compile it yourself, recent builds list the compile options or you can check with ffmpeg.exe -formats
