You state in RocketChat/Rocket.Chat#35110

We disabled Open Video Chat using Application Window. And then in Chrome we can share the screen or a window.

And according to this it looks like it needs an update to the underlying Electron SDK, and Jitsi itself. So it's going to be a while before you get a fix and you have a workaround for now.

I'll ask the team for comments.

According to the latest answer in jitsi/jitsi-meet#15574 (comment), it should be fixed by updating the Electron SDK to version 7.

Does anyone from the staff of rocketchat knows, when this will be fixed on the Rocketchat Clients?
We have a paid subscription, would be nice, if it could work again. Thanks

When it gets done. It has to go through multiple layers and departments and I would expect it normally would take a couple of release cycles at least, depending on other priorities.

In which case you should use the correct channel which is support, and raise an issue there. You can quote this Issue as a reference.

Note that Github is really just the released end product. It is not the primary source of code or issues for Rocket. That is what paid support and the ticketing system is for.

The new update is frustrating, sorry to say this.

[moell9]

I'm in contact with people from Jitsi.
They say and ask:
There is a fallback mechanism that should kick in. What Electron SDK and Jitsi Meet versions do they use?

👋 Hey there Saúl from Jitsi here.

Looks like RocketChat is not using the Jitsi Electron SDK (https://github.com/jitsi/jitsi-meet-electron-sdk) but rather including the piece of code that made screen-sharing work directly.

This had the unfortunate consequence of RC missing on the SDK updates that migrated the way to do this "the right way".

We are on the 3rd (and hopefully final, since we are now using getDisplayMedia, like browsers) of screen-sharing.

RC currently implements the old-old mechanis, which we dropped after we added the latest one. We still keep compatibility with the old one, but not with the old-old one that required injecting a global in the render process.

In both the old and the new the mechanism relies on the external API for signalling the sources.

I'd suggest using the SDK so you can get these updates going forward.

Cheers!
