ffmpeg can only be built with MinGW, and we found that 64-bit MinGW ABI is incompatible with 64-bit MSVC ABI. That's why on 64-bit Windows ffmpeg is not availble. This is feature. I'm changing the ticket type from defect to enhancement.

This ticket is related to the one I opened (#677).

The 64-bit MinGW ABI issue has been fixed. I've also written instructions for building static libraries that are compatible with MSVC:
