the obvious way:

#define mp_msg
#define MSGL_ERR 0
#define MSGTR_OpeningVideoFilter ""
...

(if there is no header that satisfies these without introducing new unresolved
 dependancies)


and once one or 2 filters work, one can look at changing these things to more
reasonable things

iam not aware of any real issue in libmpcodecs for porting it but as said
it needs someone with a bit more experience in such porting, aka this is
probably not a good case for ones first such project
