Well, that depends... The general case is that we use ffmpeg to decode
WMV/WMA. There is an exception to this. VLC can use the DMO API to
Wdecode WMV under windows. We don't have any wrapper for windows libs
Won other OS since that would violate the GPL (It only allows to link
against proprietary libs if they are part of the OS).
