Ah, spent time doing something impossible. When using mingw, it is not possible to use any Windows-SDK libraries, as they conflict (mingw is a minimalistic Windows SDK). Thus, when using mingw, Windows SDK must not be used. There are several websites/threads which describes how to use DShow with mingw, using the old Direct-SDK which was shipped independently from the platform SDK. E.g. see: http://old.nabble.com/MinGW-%2B-DirectShow-td17933085.html http://nova.polymtl.ca/~guardia/programming.php Maybe you will add this information to the Wiki, so that others don't waste time in trying impossible things :-) I have not tried the referred approaches, I think I will try again using VS instead of minGW. regards Klaus
