mpv updated to a new version a few days ago (0.27.2-13.5.1)
Since then I am no longer able to play files on my NAS drive over a smb connection.
The error log shows
Playing: smb://ls-chl/share/TV Shows/The Crown/s02e01.mp4
No protocol handler found to open URL smb://ls-chl/share/TV Shows/The Crown/s02e01.mp4
The protocol is either unsupported, or was disabled at compile-time.
Exiting… (Errors when loading file)
rolling back to previous version of mpv resolves the issue.
