Hi all, I've patched theora-mmx to build on x86_64. The patch against SVN is attached. Basically all I did was to copy lib/i386 to lib/x86_64 and tweak the assembler code a bit: * added to each file: typedef unsigned long int ogg_uint64_t * converted all asm inputs to 64-bit in: dsp_mmxext.c, fdct_mmx.c, recon_mmx.c * left all asm outputs at 32-bit * I didn't patch dsp_mmx.c, since all
