I think it would be very helpful to add to
https://wiki.videolan.org/Win32Compile/ the reqirement of mingw-w64 of version 5.0
As of today for example
on UBUNTU installs version 4.0.2. It won't build because of the lack of wrl library. To build VLC you have to build and install mingw-w64 5.0 manually. I think this would save a lot of time to people trying to build VLC without deep knowledge of closs compilation. If there is an instruction of how to build MinGW it would be very helpful too.
