Hello, I was trying to compile gstreamer with meson on Windows Msvc 2017 x64 compiler. I received this error. Since, it was coming rom FFmpeg/avcodec.lib I think this issue will be appropriate on here.

I am guessing you include winsock.h or winsock2.h or visa versa in somewhere on your code.

I shouldn't modify winsock or w2def.h or any Windows header file so any help would be appreciated. Thanks,
