Woohoo!  I compiled CVS as of last night, and sure enough, it came up nicely
on my 500MHz G3 iBook.  Of course, playback was painful, etc, but that is an
exercise in tweaking for later.

Fair enough.  At least the CVS code seems to be mostly operational as it stands
now.  This gives me enough ammunition to start looking at tweaking for my poor
non-Altivec processor :)

Nice.  Just please make sure that the CVS way works too :)  hehe.

I ran Shark on my iBook, and found out something interesting.  about 20% of the
CPU time is used to resample my audio.  Seems the iBook can only native play
44.1kHz sampling...  and all my recordings are 48kHz.  Just wonderful.  I will
try again with 44.1kHz recordings, see how things go.  Once that's all done, I
may look at optimizing some of the libavcodec stuff for the non-altivec case.
Yeah, I'm a sucker for punishment. :)

P.S.  Is there any official sentiment on having CPU-specific assembly added for
some of the video decoding stuff?
