@seeker said in Video chat and conferencing options:
While there are many solutions around that could fit your needs, I can only share what I am personally using/recommending for the various use cases you describe:
I am still looking for:
Single login (or as few as possible)
Use oidc (OpenID Connect) whenever possible. As for oidc providers: you can use Kopano Meet (check @fbartels post on this for further information: Link) or Rocket.Chat as oidc providers for example. Many apps (Nextcloud, Rocket.Chat, NodeBB with plugin) support OpenID Connect.
File sharing (similar to next cloud)
I personally like Nextcloud for file sharing (and just for that purpose)
1 on 1 video chat ( single click would be nice to launch)
Kopano Meet is a great option here. No plugins necessary, works on mobile devices, private (internal) and external video chat with guests possible.
Group chat ( similar to google hangouts or zoom)
For group video chat, something with a MCU/videobridge would be necessary. Jitsi would be great for this, but packaging seems to be not an easy task.
Screen sharing , white boards, ether pad integrated in video call
For small groups with just a few people working on a document together, Nextcloud Talk with OnlyOffice would be an option as well.
Sharing prerecorded video
Not sure about that, maybe Nextcloud?
Ability to create & join conference from smartphone
Both Kopano Meet and Jitsi can be uses from mobile devices. Jitsi needs an app, Kopano Meet uses the WebRTC support available in all modern web browsers.
Recording web conference ( can use OBS)
Remote Desktop like teamviewer. Had not thought about this, but this would be amazing.
Not sure about those two. I‘ve read about a self hosted open source alternative to TeamViewer, but haven‘t had a chance to give it a try (would have to see if I can still find the link to that).
Update: The TeamViewer alternative I was writing about was this: https://www.meshcommander.com - never tried nor looked deeper into this though...
