[Ffmpeg-devel] win64?

[Clarke, Trevor]

Thanks....I think I've got something that works now...at least enough
works for my use. Once I got the MSVC version, the 64-bit compile was
pretty clean w/o the asm. I'm just encoding so I'm not too worried about
the speed hit from not having asm code.

You need DrFFMPEG from DrDivX. It's not based on latest SVN from FFMPEG 
but rather a version from a few months ago. We plan to merge many 
changes into DrFFMPEG soon.


DrFFMPEG will work in MSVC8 (and VS Express) in Debug, Debug ASM and 
Release. There should be a "Release ASM" but we don't use it. The ASM 
uses something called libavdsp that is built with gcc as a DLL and 
includes all the ASM stuff in i386. So it should work with a Release 
build too. Otherwise you just have no ASM acceleration.
