If you provide a patch with intrinsics that can speed up libtheora, I'm sure it will be accepted, even if the maintainers decide to recode it as inline assembly. > As a first step, I'll be converting the existing MMX and MMXEXT assembly code.

Sounds good to me! --Ben _______________________________________________ theora-dev mailing list [email protected] http://lists.xiph.org/mailman/listinfo/theora-dev
