I'm using Kodi 15.1 and would like to detect my video's that are not part of my library.
I used to have an add-on that could do that. I think it was Missing Movie Scanner
http://kodi.wiki/view/Add-on:Missing_Movie_Scanner
However I am unable to find that add-on in the list of available add-ons.
It does however show the add-on Missing Movies
http://kodi.wiki/view/Add-on:Missing_Movies
That add-on however does not seem to work at all....

How can I install Missing Movie Scanner?
