After I tried EMBY/Jellyfin and PeerTube (actually unstable), it all doesn't fit our needs I think.
So I just wanna leave her the suggestion of the installation of Kaltura:
Please leave your thoughts and comments.
Just to add, in the duplicate post @atrilahiji has now deleted he pointed out that Kaltura plays nicely with Moodle (which we now have on Cloudron thanks to his great packaging efforts ) so that's another reason to upvote it
For more info see e.g.
https://learning.kaltura.com/channel/Kaltura%2BExtension%2BCourse%2BFor%2BMoodle/80498092 (this last one looks like it's a Moodle course using the Kaltura module, on how to use the Kaltura module for Moodle! )
