The 'inactive' event is fired whenever the stream gets inactive (ie it
cannot be used anymore), and there are scenarios where that is
unexpected behavior and must be handled accordingly.
The main example of that is when gUM permissions are revoked by the user
via the browser's permission management panel.
Since MediaStream/Track inactive events aren't being handled in such
scenarios, what actually happens is that the camera just freezes without
further indication why.
This commit handles those scenarios in both video-preview and
video-provider by:
- 1) correctly stopping the camera (provider)
- 2) surfacing a toast (provider) or error indication (preview)
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
Include `userCameraCap` API param on create and enforce both server and
client to control the number of simultaneous webcams an user can share.
Default set to 3.
Video preview modal opens when user clicks on the webcam selector
button/chevron even if the client is set to skip video preview
(userdata-bbb_skip_video_preview=true).
Another round of experimentation with that button.
Removing it due to its role being already contemplated by two other actions in the modal: clicking outside and the X icon
Will have to see how this is received in internal testing
