This is a well-known issue (meaning: google would have been your friend), involving a clash between various header files (qedit.h, d3d9.h, vmr.h). See http://tmhare.mvps.org/faqs.htm#qed for example.

G

content from tmhare's site: You probably also have in your include file list. This is a known issue and the workaround is to split your code that uses VMR9 and the code that uses DES and related functions like IMediaDet into two separate source files. This means that you can't put either header file in a precompiled header such as stdafx.h.

An alternative solution was posted on the newsgroups by chadderack. He uses the #define below so that the conflicts are avoided:

#ifndef __D3DRM_H__
#define __D3DRM_H__
#endif

#include <dshow.h>
#include <d3d9.h>
#include <vmr9.h>
#include <qedit.h>
#include <dxerr9.h>
