Yes. It's the same process as on win32, except use mingw64. For best results, use the latest revisions (i.e. trunk) of BOTH mingw64 and ffmpeg, since for a while there were a few weird hacks in ffmpeg that made this a difficult proposition. I've done it, and FWIW, it didn't seem to improve performance much -- it just increased memory usage (as expected). In fact, since most of the ASM is x86, I'd expect performance to be worse. I think x64 optimizations are being worked on right now. The only reason to do it is if it needs to be integrated into an existing x64 binary. -- Hide the petals underneath that bedroom floorboard and they will wither without fail or success; Put the people in the hollow box they crafted, bolt the doors and watch them perish. - Circle Takes The Square
