Since finding out if a binary is 32 or 64 bits involves a major effort
on Windows I'm not convinced he actually checked...

I think this is a very bad idea, involving a major effort, libmpcodecs
has strong dependencies in MPlayer and a lot of information that is
simply useless for decoding.
I think you should better consider providing RPC-like stubs of (for
decoding DMO):
DMO_VideoDecoder_Open
DMO_VideoDecoder_SetDestFmt
DMO_VideoDecoder_StartInternal
DMO_VideoDecoder_Destroy
DMO_VideoDecoder_DecodeInternal

To implement these you need only the loader code, which should be much
easier to compile stand-alone.
