Comment (by cehoyos):

 Afaict, the functions (that currently only use forceinline) defined in
 dxva2api.h all have to be defined "static" (as it is done in many internal
 FFmpeg headers, for example libavformat/network.h).

 Could you report this to the w64 mingw-runtime developers?
 (Or am I missing something?)

 An alternative would be be to try
 #undef __forceinline
 #define __forceinline static av_always_inline
 before including the header.
