 Summary of the bug:
 How to reproduce:

 I build ffmpeg's latest version (4.4) under Windows using MinGW.
 I do this:
 {{{
  ./configure --target-os=win64 --arch=x86_64 --toolchain=msvc --enable-
 shared
 make
 make install

 ffmpeg version 4.4
 built on Windows 10 (x64)
 }}}

 Then I load the produced DLLs (avcodec-59.dll, avformat-59.dll, etc...) in
 a Windows application I have developped.
 This application can then decode the most common video formats but I
 cannot decode any AV1-encoded video.

 And yet the av1 codec appears in the list of supported codecs when I run
 "configure".

 Does anybody know why?
 Do I need to specify a special option during compilation?

 Thanks in advance
