[MPlayer-dev-eng] [PATCH] support for video codecs from Vanguard

[Andreas Hess]

Hi,

I came across some codecs from Vanguard (http://vsofts.com/solutions.html)
today. I've added them to the codecs.conf and they need a currently not
implemented API call to access the registry, so I've added a dummy function
to implement it too. (Maybe there is a better solution?) Two of the 3 codecs
are working, the other one can't find a function, that is in an other dll.

The codecs and sample files can be found at http://vsofts.com/solutions.html .
