Are you thinking of creating a native win32 interface plugin? I've

aware that there are some legal issues:

The MMX plugins do not compile with msc because gcc uses a different
format and syntax for its inline asm. You will have to write new ones
for msc' inline asm, or use either masm or nasm. This has been
considered a non-issue since official vlc win32 releases will be
compiled using mingw32 (
