[MPlayer-users] Is there any plan to include win32/64 dll codecs feature for x86_64?

MSS2 should be work in progress.

Yes.
As to your question: I believe a long time ago someone made
a stub program that would load and control a binary codec and
MPlayer would through pipes/shared memory send it commands.
It would then not matter how MPlayer was compiled, only
that stub needed to be 32 bit.
Using them directly will not be possible since the Linux kernel
does not allow executing 32 bit code in a 64 bit process.
And support for 64 bit codecs will probably require an
amount of effort that's just not worth it.
