Do you really expect any speed advantages on 64 bit for video encoding? I dont think that video encoding needs more than 2G Ram or real 64 bit integer math. And with SSE2 enabled the 32-bit code shouldnt be slower, or?
When libavcodec wasn't x86_64 asm optimized, I was getting about 20 fps in 64 bits mode and 22 fps in 32 bits emulation, and now that's it's asm optimised, I get about 60 fps, so yes I think it make an hudge difference :-)
