Added support for getStats in screenshare's service. This works similar
to the getStats for video provider, and the information retrieved from
screenshare is added to the video information for cameras.
isFullscreen is a state property and is being fetched from the component
props. I think this is something I messed up while resolving a cherry-pick
conflict.
Change the previous loading spinner to the new loading dots, ensuring
a bit more UI consistency.
Add the "unhealthy stream" filter to make the dots a little more visible and
remove the loading spinner.
Shave off the number of calls in video-preview and video-provider by
using a stream storage
We don´t call an upfront gUM in video-preview anymore to lift the
fingerprinting barrier on device labels and IDs. Flow has been reversed:
upfront enumerate, load first preview, then check if previous
enumeration was obfuscated.
Add a stream storage in video-preview`s service to avoid re-fetching
them in video-providerj
Remove some unneeded video-preview container props
Improve some of video-preview`s error locales
Add the shrink/expand button in the screenshare layout to reduce the mirror/tunnel
effect, when the presenter is sharing the same screen as the application is.
If the presenter gets changed while the user kept the getDisplayMedia browser picker open, accepting the getDisplayMedia prompt might get the previous presenter´s client-side state inconsistent as if they were sharing. The screen sharing is a no-op though
This adds a check after gDM resolves to see whether the user is still the presenter; if they aren`t, just clean up the gDM stream and make it a full no op
Adapted the breakout room screen sharing shutdown to use the new refactor calls
Also changed the behaviour a bit to only trigger the stop code for presenters/sharers, mimicking the camera behaviour and not leaving viewer with stuck screens
Mainly: track unhealthy fatal states instead of supposedly healthy states
Avoids unwarranted UI reconnecting states or flickering on low end devices or struggling networks
Also added a version of isVideoBroadcasting for presenters which only accounts for the server state, so that we can deal with the presnter`s sharing state with more fidelity in the UI
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!!!
When refusing ("thumbs down" button) echo test, user is able to select a different input device. This should work fine for chrome, firefox and safari (once user grants permission when asked by html5client).
For output devices, we depend on setSinkId function, which is enabled by default on current chrome release (2020) but not in Firefox (user needs to enable "setSinkId in about:config page). This implementation is listed as (?) in MDN.
In other words, output device selection should work out of the box for chrome, only.
When selecting an outputDevice, all alert sounds (hangup, screenshare , polling, etc) also goes to the same output device.
This solves #10592
This adds support for screensharing on Safari 12.1+ or whichever has getDisplayMedia enabled
To be conservative and backwards compatible, I`ve maintained the current gUM-based code available as a fallback for those still using older versions of FF or Chrome
Made screenshare constraints configurable. The constraints config will be piped directly to gDM, so it`s just a regular gDM constraint dictionary
