Direct reference to my statement that using the AAC codec produced a much
better audio stream than using libfaac. I know, I know libfaac and faac are
not one in the same. Close enough though. I read that FAAC and libfaac are
only slightly different. I will test faac later. 

When I mentioned that I needed to use -strict_experimental flag in order to
use AAC I was told that the reason is because AAC is a poorer quality codec
than libfaac even though my own ears heard the exact opposite.
