FreeSWITCH has mDNS resolution capabilities as of 1.10.7. Having the filtering
configurable in the client allows us to field trial whether we should keep that
on or off. The default is still to filter them out because FreeSWITCH does not
resolve mDNS candidates by default (ice_resolve_candidate in switch.conf.xml).
- Remove the old listen only bridge (kurento.js), superseded by the equivalent
and equally stable (AS FAR AS LISTEN ONLY IS CONCERNED) sfu-audio-bridge
- Rename FullAudioBridge.js -> sfu-audio-bridge.js
* A more generic name that better represents the capabilities and
the nature of the bridge
* The bridge name identifier in configuration is still the same
('fullaudio')
- Remove the FreeSWITCH listen only fallback
- Temporarily disable the "trickle ICE" pair gathering feature used
in SIP.js (which was always experimental, nonstandard and disabled
by default)
- Updates to settings.yml keys in places where relevant
mediasoup is the default media server in v2.5, so we don't need ICE candidates
to be signaled to bbb-webrtc-sfu. Disabling it saves resources (client and server).
public.media.showVolumeMeterInSettings => public.media.showVolumeMeter
public.media.simplifiedEchoTest => public.media.localEchoTest.enabled
Initial hearing state can be configured in public.media.localEchoTest.initialHearingState
New features:
- A simplified echo test mode that only does a local loopback (instead of
going to FS and back)
- A volume meter for microphone streams to the AudioSettings view
Those two features are experimental and disabled by default; see
public.app.media.simplifiedEchoTest and public.app.media.showVolumeMeter configs
Collateral changes:
- fix: localize fallback device strings in AudioSettings/DeviceSelector
- Refactor on some media stream utils to be re-usable across components
- Refactor in AudioSettings to keep gUM #uses stable.
* TODO: need to pass streams through AudioManager to avoid the surplus gUM.
- fix(audio): drop ScriptProcessorNode usage (deprecated)
* Used in volume meter for tracking - use hark instead
Rationale: the important thing here is bitrate. Disabling constraints should have no meaningful on 1) client-side bw 2) client-side cpu 3) server-side bw/cpu - while it will also guarantee seemingly smoother streams
Tries to mitigate too-rapidly-switching camera profiles causing video freezes
due to encoder resets. Excluding constraints might not help a lot since
the thing that actually restarts the encoder is the bitrate change, but
they're not really important in the context of dynamic profiles.
We can't get rid of bitrate changes, though, since it's what does the actual
quality constraining.
The camera profile change debounce timer is 2.5s by default (which is
the same timer used for floor changes).
Also fixed an issue with camera profile backfiring due to badly defined peers
Set height to 720 in those profiles so that aspect ratio has a better chance to
be cohesive in all environments. Having only width set was causing certain
devices to output videos with non-standard ARs

Since bbb-pads the html client Etherpad redis' channel subscription isn't
needed anymore. All communication between Etherpad and BigBlueButton goes
through bbb-pads.
Move all Etherpad's access control from Meteor to a separated [Node application](https://github.com/bigbluebutton/bbb-pads).
This new app uses [Etherpad's API](https://etherpad.org/doc/v1.8.4/#index_overview)
to create groups and manage session tokens for users to access them. Each group
represents one distinct pad at the html5 client.
- Removed locked users' access to pads: replaced readOnly pad's access with a new pad's content sharing routine
- Pad's access is now controlled by [Etherpad's API](https://etherpad.org/doc/v1.8.4/#index_overview)
- Closed captions edited content now reflects at it's live feedback
- Improved closed caption's dictation mode live feedback
- Moved all Etherpad's API control from Meteor to a separated [app](https://github.com/bigbluebutton/bbb-pads)
- Included access control both in akka-apps and bbb-pads
