I import ffmpeg library, but Dword symbol ambiguous error exists.

Hi.
I insert ffmpeg headers like this, but errors not disppear.
#include “AllowWindowsPlatformTypes.h”
#include “ffmpeginc.h”
#include “HideWindowsPlatformTypes.h”
there are follow souce code in ffmpeginc.h file

    #pragma once 

    #ifdef __cplusplus 
    extern "C" { 

    #include <libavutil/avutil.h> 
    #include <libavutil/imgutils.h> 
    #include <libavcodec/avcodec.h> 
    #include <libavformat/avformat.h> 
    #include <libswscale/swscale.h> 

    } 
    #endif

-this is the error
1>C:\Program Files (x86)\Windows Kits\8.1\include\shared\rpcasync.h(126): error C2872: ‘UINT’ : ambiguous symbol
1> could be ‘C:\Program Files (x86)\Windows Kits\8.1\include\shared\minwindef.h(177) : unsigned int UINT’
1> or ‘C:\Program Files\Unreal Engine\4.4\Engine\Source\Runtime\Core\Public\Core.h(491) : DoNotUseOldUE4Type::UINT’
Please explain how can I fix it.
