Edit: if you have a link of the video on the arte website, you might wanna try to copy the link and put it into yt-dlp. It is capable of downloading from youtube with sponsorblock information but also capable of downloading videos from other sites. For example the ARD Mediathek or Arte.
Tried to open that webpage but godaddy asks me if I want to buy the domain. Typo?
You can also selfhost in a container
mediathekviewweb.de/
https://github.com/mediathekview/mediathekviewweb
https://github.com/conrad784/docker-mediathekview-webinterface
I think he has a typo, yes. The correct link:
mediathekviewweb.de
