I get the same error with the version of ffmpeg from macports. I
hadn't tried this version before, since I had ffmpegX, and I knew it
would take a long time to compile it. Sorry if I implied that I had
tested both versions.
It looks like the macports version (SVN-r15261) is a few thousand
commits behind trunk (r17576), but still newer than the ffmpegX
version. I'm not sure what is causing the problem, however, I noticed
that ffmpeg from macports is recognizing the audio as 'mp3' and using
libmp3lame for output. The ffmpegX version recognizes the audio track
as 'mp2', and uses 'mp2' for output.
I tried forcing the framerate, but that doesn't seem to work. I would
just download ffmpegX[1] and use ffmpeg from the bundle. Note that you
don't even need to install the app, just mount the disk image and
sudo cp -p /Volumes/ffmpegX_0.0.9y/ffmpegX.app/Contents/Resources/
ffmpeg /usr/local/bin
