[FFmpeg-user] How to build 64-bit ffmpeg using msvc toolchain?

[Yaming He]

Hello, I am building the ffmpeg by using MSVC toolchain. By
default it generates the 32-bit build but I want have a 64-bit build. I used
the below configuration flags but it always generate the 32-bit binary. Did I
miss anything? How to build a 64-bit ffmpeg with msvc toolcahin?
 
./configure --toolchain=msvc --enable-shared
--disable-static --target_os=win64 --arch=x86_64
 
Thanks.
