Thanks for reporting @TheDalaiAlpaca, this is related to this: https://trac.videolan.org/vlc/ticket/19689.

MotionBox Youtube backend currently uses input-slave to play both video and audio sources. Unfortunately that feature is a bit broken since VLC 3.0.0.

Hi, I can live with that!

I've some other minor issues to report if you'd like, mainly affecting Linux.
