ffmpeg only giving me 32kbps

[BlueScreen]

Here is my command line invocation of ffmpeg:

Code: Select all

ffmpeg -i ~/2.One_Of_Us.m4a -acodec libmp3lame -ab 128k -ac 2 -ar 44100 ~/OneOfUs.mp3

And I get the following as output:

Code: Select all

glenn@Design ~ $ ffmpeg -i ~/2.One_Of_Us.m4a -acodec libmp3lame -ab 128k -ac 2 -ar 44100 ~/OneOfUs.mp3

So I should have a bitrate of 128k, but when I play it, I've only got a bitrate of 32k.

Can anyone enlighten me of where I went wrong?
