Benchmarks Inline-ASM vs. Intrinsics
...'ll take the current version from the trunk with all
inline assembler functions enabled. Lower values mean lower performance.
All functions with inline-asm: 100%
inter_mmx replaced by C-function: 93%
no mmx at all: 60%
all oc_frag functions intrinsic based: 98%
As you can see the current bugfix for mozilla just takes a 7%
performance hit. Imho that's something we could live with. The intrinsic
based approach is nearly as good as the handwritten code, and it
compiles with gcc as well as VS.net (haven't tried it...

theorarm build
Hi all--
I tried building the ARM-optimized theora codec from the theorarm-
merge-branch, and encountered the following compile and runtime
problems before getting something to run. If there is another way to
build it, it would be nice to know, but I got the sense that its
current state in svn is incomplete.
I'm using a gcc cross-compiler for ARM on an x86 Linux PC. After
running
