I think the 3GP output format uses the AMR audiocodec by default. FFmpeg
does not include a native AMR encoder, but you can hook one into it by
following the advice in ffmpeg/libavcodec/amr.c.

Oh yes, next time you should post usage related questions to the 
mailinglist. This mailinglist is used for discussions related to FFmpeg

With friendly regards,
