Making libmp3lame work with ffmpeg on OS X

I wanted to convert some youtube footage to mp3 by using the Firefox addon DownloadHelper together with ffmpeg.

Ok, installed ffmpeg on OS X using MacPorts:

sudo port install ffmpeg +gpl +lame +x264 +xvid

Tried to convert a file. Got this error:

[libmp3lame @ 0x1804600]lame: output buffer too small (buffer index: 8360, free bytes: 1432)

Turns out this is a known bug with version 3.98.2 of libmp3lame, which, incidentally is the latest version on MacPorts.

I tried version 3.98 and it seems to work.
This guide tells how to install an older version of a port.

To save you some trouble, these are the steps I took to make it work:

cd /tmp
curl -O http://trac.macports.org/export/38059/trunk/dports/audio/lame/Portfile
sudo port install

Voila! ffmpeg can now generate mp3s without errors.

Thanks. I’m sure upgrading to Lion would fix me up, too, but this was quick and fixed me right up.
