 Summary of the bug: FFmpeg 4.3+ does not work on Windows N editions
 without the Media Feature Pack installed

 Windows N (and KN) editions intentionally do not contain Media Foundation
 components. FFmpeg 4.3+ includes a wrapper for Media Foundation encoders.
 Attempting to run FFmpeg 4.3+ on a Windows N system results in a DLL
 loading error.

 This error also occurs in the latest git-master. This also occurs when
 trying to load libavcodec 58.86.100 or newer on a Windows N edition.

 While one could compile with --disable-mediafoundation, it would
 necessitate providing different versions for users on different editions
 of Windows, or walking users through installing the Media Feature Park. It
 would be ideal if FFmpeg/libavcodec would continue on without Media
 Foundation features if they are not available on the user's system.

 How to reproduce:
 {{{
 % ffmpeg -version
 ffmpeg.exe: error while loading shared libraries: MFPlat.DLL: cannot open
 shared object file: No such file or directory
 }}}
