I'm certainly not an expert in such matters, but I could imagine that you'd have to create 3 Kodi smart playlists (morning, afternoon, late) with perhaps each set of videos in their respective folders, and activate the next/upcoming playlist via a timer. The timer perhaps could be done via a so-called 'cron job', which is a Linux OS background timer thingy.
thanks Klojum... I'm looking for "cron job" but I'm not very good... I've just read about "pseudoTV" to schedule video... I'm trying to understand how it work...
