Since updating mpv to 0.32.0+git.20200307 I am unable to play media files on my
NAS over smb
Rolling back mpv to 0.32.0+git.20200301 I can then play over smb again

Error reported in smplayer/mpv is . . .

warning: option --input-file is deprecated and might be removed in the future
(use --input-ipc-server).
[ffmpeg] Protocol not found. Make sure ffmpeg/Libav is compiled with networking
support.
Failed to open smb://ls210/share/TV/TVShowname/s01e01.mkv.
Exiting... (Errors when loading file)

However, error is not caused by ffmpeg as only mpv has been updated and a
rollback fixes the problem
