Interesting article, and kamedo2 provides some comments about ffaacenc
that are worth a follow-up (and he has a blog that has some opinions on
libvo-aacenc quality compared to others http://d.hatena.ne.jp/kamedo2/).

Also, I've noticed that libvo_aacenc ignores -aq/-q:a, so you're stuck
with -ab/-b:a for that encoder.
