The only scenario in which the screensharing is technically working with acceptable performance is when the user has xuggler installed and configured.
Xuggler no longer maintains windows binaries, so users would have to compile xuggler themselves which no one will do.
The screensharing is a usability catastrophe and features 10+ severe usability issues, including privacy related problems. It fails to work for most users and when configured it does not work reliably.
I propose removing this feature and reintroducing it later when it was reimplemented properly. I cannot believe there is even one users that is actually depending on this feature who would complain about the removeal, because there are many free tools available for screensharing that work way better than this piece of code.
The user experience and the trust in the quality of saros is dramatically reduced by experimental features that simply don't work for most users and work annoyingly bad if they manage to configure it. For a commercial software that would be inacceptable.
