You should apply the fix made in
http://git.videolan.org/?p=vlc.git;a=commitdiff;h=bb7509af051d8384b9266bcdb345c553f608559c#patch1

Using the secure versions would be better but mingw.org doesn't have them afaik.

Subject: [PATCH] dshow_filter: fix compilation with mingw-w64

Closes ticket #999
NO_DSHOW_STRSAFE asks dshow.h header to not use secure string function
replacements.
Using secure replacements would break mingw.org compatibility as they don't
declare/define those functions.
