[Theora-dev] CPU usage while encoding...

I would love to use theora-mmx or theora-oil on a Win32 system but I
can't get either to compile.  I understand that liboil only compiles
with gcc anyway.  Being fairly new to inline asm I haven't a clue
where to start.

Currently I'm using the reference theora encoder, but in a dynamic
"dll" form which works great for me (apart from being slow).  Are
there any plans to convert any of these wonderful optimisations so
they can compile for msvc or vc2003?

Probably I can't use Theora for my application :(

you've been testing you might try the -mmx or -oil branches.

The -oil branch uses liboil, which only compiles under gcc.
