I have growing concerns about gain node`s effect on audio quality the way it
was implemented, so I opted to fall back to HTMLMediaElement`s volume control
for the time being until we can gauge quality impacts properly later on
Add a new configuration flag enableVolumeControl, false by default while the
feature undergoes a field trial
Splits screenshare stream into video and audio and adds gain node to audio
stream in order to permit volume control by the user. Volume is normalized
between [0, 2](muted and 2x boost).
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
