If you like you can add the VIDFLTR Add-On to your KODI Mediacenter.
Just add repository.bassdart.zip via the usual "Install from zip file" menu (obviously you have to allow installation from unknown sources at Settings/System/Add-ons) in KODI and afterwards install the VIDFLTR Add-on in the Add-on Browser from the Repository "Bassdart Add-ons".
If you want to look at the source beforehand head over to plugin.video.vidfltr.
The Add-On is tested on CoreELEC 9.28 (KODI 18.9.0, Python 2 based) and CoreELEC 20.5-Nexus (KODI 20.5.0, Python 3 based) but maybe also works in earlier or later KODI versions (The Add-On does not forcibly depend on any xbmc.python aka KODI version).
As we all know playing Youtube videos in any non-official client is a moving target and gets more and more difficult -- especially without an Youbtube account and configured Developer-API access tokens.
Without an Youtube-Account configuring the following resolvers for Youtube in the VIDFLTR Add-On works for me:
In Kodi 18, Youtube plays only the non-dash maximum resolution (mostly 640p, some 720p), really slow resolving: plugin.video.sendtokodi
In Kodi 20, Youtube plays in FHD (and maybe better, can't test), a bit slow but usable resolving: plugin.video.invidious installed from lekma repository which is then resolving the streams with service.yt-dlp (also from lekma).
Other providers (e.g. Vimeo, Dailymotion, Vevo) should just work with the default settings (Also Youtube if you have an API-Account configured).
The fastest resolver is playing from local files but this (currently) only works on my machine ;)
