[MPlayer-cygwin] Using third-party MPEG decoders

I did some of this - the reading part at least. My conclusion 
is that DxVA is best implemented in the MPEG decoder library. 
I looked at the libmpeg2 as well as ffmpeg and found that 
it wouldn't be easy to shoehorn DxVA support in either. Both 
are very Unix-centric and to add a Windows-specific feature
in either would probably require considerable work. This is 
beyond my capabilities. 

So I looked for Windows-specific MPEG decoders and found a
few that also implement DxVA. Some of these decoders can
be used with more than one media player. I don't know how
they interface with these media players but I was curious 
to find out if mplayer could use any of these.

It is very likely that I am not even asking the right questions.
I found out about DxVA and have been trying to figure out how to
use it. I was hoping that the MPEG decoders I mentioned had some
standard interface and I could tell mplayer to use one of them
instead of the default. Essentially I was hoping to switch out the
default MPEG decoder library with one of these.

One piece of information I found since I asked my question 
yesterday is that the Windows decoders I mentioned are all 
DirectShow decoders and not DMO decoders. I don't know if 
that means something to you all and if that helps answer the
'can mplayer use it?' question.
