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...

Maybe. I've been working with Speex for some time, so I'll help where
I can -- but in the asterisk community, people are enamored with iLBC
(free, but not open-source), and G.72x (patents and licenses and all). <br>
<br>
I'll also need to do optimization work for PPC, because my application
needs to be able to perform well on PPC as well as x86.<br>
<br>
I'm sure there's headroom there to make things work, so it's not my
primary concern.. The quality I see so far with this seems acceptable,
but x264 seems to be still better..<br>
