...ff.bz2 It adds a 3dnow! decoding speedup (about 10%), SSE decoding speedup (about 20%) and SSE encoding speedup (about 25%). The code selection happens purely at compile time, no CPU flag detection or so. I figure someone else will have to do that, I'm short on time. To activate 3dnow!, add -Dsimd_3dn to CFLAGS. To activate SSE, compile with gcc 3.2.2 (others have had alignment problems), compile with optimizer enabled, and add something like -march=pentium3 -msse to CFLAGS. I probably haven't even remotely touched all the parts that would be beneficial to speed up, but I don't even kn...
