Reconnection timers are far too long for abrupt failures because we
are waiting the original timeouts to elapse (30-60s) before trying it
again - even if a connection worked N-sessions back in that session's
history. The ideal thing to have is another intermediate, smaller and
fixed reconnection timer for sessions that had a working screen share
at least once.
The UI is also not being updated to the reconnecting state on negotiation
failures.
* Add an intermediate reconnection timer for abrupt failures set to 8s.
This should improve reconnection times.
* Lower default connection timers values (base 20s down from 30s, max
25s down from 60s)
* Set screen share UI to reconnecting on abrupt failures as well - we
were only tracking ICE states prior to this, not negotiation errors
There could be a race condition where the local getDisplayMedia stream ends
(eg via Chrome`s stop sharing toast) while the broker hasn't finished starting.
That would lead to a scenario where the broker wouldn't emit an end event,
causing screen sharing to be flagged as started with a blank/invalid stream.
Added new SFU broker for screen sharing
Removed kurento-extension entirely
Added inbound and outbound reconnection procedures
Improve UI responsiveness when sharing
Add reconnection UI states
Redo error handling
Refactor actions-bar screen share components. Make it smarter with less prop drilling and less re-rendering. Also more readable. Still work to do in that I think
Add a connection retry procedure for screen presenters when they are sharing; try a configurable amount of times when failure is triggered, with configurable min and max reconn timeouts and timeout increase factor
Make local preview attachment smarter
ADD PARTIAL SUPPORT FOR AUDIO SHARING VIA SCREEN SHARING WITH GET DISPLAY MEDIA, RECORDING STILL NOT SUPPORTED!!!
