Happend again. Looks like conference with only 2 users is not affected Three and more - even webcameras give poor resolutions. When caster quit conference in Electron - cameras became better. Then he rejoin with browser client.

We are experiencing the same; if you use Rocket Chat in the browser, all videos/screens share in 4k/HD; if the Electron app is used, its only allows 320p for videos and screen shares...

All versions are up-to-date client+server

Please have a look here, we have more or less the same: https://github.com/RocketChat/Rocket.Chat.Electron/issues/2808

We're having the same problem with the electron client when more than 2 people join a call. Both Client and Server up-to-date + locally hosted Jitsi server ( We had the same problem with public jitsi too). As a temporary work around we've sent a notification to our users to disable "Open Video Chat using Aplication Window"

Same problem with client 3.9.12.

Same problem with client 3.9.13. That's very frustrating.

Trying to debug it I found that when there are more than 2 persons on the call it changes from p2p to conference and changes to SenderVideoConstraints: {"idealHeight":360}.

And if the sharer is a Chrome browser, it and the Electron enters the call it changes the ReceiverVideoConstraints to "maxHeight":360. Making the quality drop.

Right now I dont know why, I will need to reach someone from Jitsi to see whats going on.

I opened an issue in Jitsi repo, awaiting their reply to see what we can do. https://github.com/jitsi/jitsi-meet/issues/14396 For now, you can disable Open Video Chat using Application Window on the settings, making it open on the web browser.
