That's ffmpeg.extra, right? If so, what's ffmpeg.unstripped for?

mpeg4 and mp3, at least. What confuses me is that ffmpeg says it was built 
without mpeg4 support, but shows as available, but does not work:

% ffmpeg -formats | grep mpeg4

Hmm ok. I guess building a ffmpeg-unstripped metapackage that pulls all 
unstripped libs might be a good idea.
