How to use Dword in unreal engine's c++?

Hi everyone.
I import ffmpeg library in my c++ project in unreal engine.
But the DWord ambiguous symbol error appears.
How can I fix this?
Thanks.

I replied to you on the answerhub thread you commented on. Trouble using windows includes with DWORD, INT - C++ - Epic Developer Community Forums

That should hopefully clear up things a bit.

Why have you made 3 threads for this same problem?
