Did my email yesterday help to clear up some of the confusion?

In a nutshell, it sounds like there are two frameworks supported in OS X 10.9:
- QuickTime (deprecated)
- AVFoundation

After the commits by Herbert and Tor, I believe that LibreOffice can
use either framework (defaulting to QuickTime, and falling back to
AVFoundation). The problem is that as of right now, there's no
documentation for adding 3rd party codecs to AVFoundation, so while
QuickTime should work for now (This needs more testing), our path
forward is unclear.

Official lists sound like a good addition to the wiki -- I'll add them!
