Yeah, you really need the -mmx branch for conferencing. There are some
decoder asm patches available as well, and I've been working on a
parallel version recent for the Elphel people.
The ffmpeg and vxid implementations have seen a lot more optimization
work than theora has. We're getting there, but working on encumbered
codecs seems to be sexier...
