ICE lite servers (eg mediasoup) dont need candidates signaled out-of-band; neither does KMS in certain scenarios
Disable their signaling saves us some ticks in bbb-webrtc-sfu and some bandwidth all around
There could be a race condition where a peer creation (async) would resolve after the provider was unmounted
That would lead to a state inconsistency which could generate all sorts of cryptic problems
Applies to video, listen only and screen sharing
New metadata values: media-server-video, media-server-listenonly, media-server-screenshare; parameter is a String
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.
We now retrieve update information about active video peers, and calculates
download and upload rates. These rates are the sum of data transfered in
all video peers.
Screenshare stats is not being added to the sum, yet.
Let the server generate subscriber offers so that it becomes easier for us to
do payload type normalization between publishers and subscribers
Also split peer creation for pubs and subs into separate methods for clarity
Should fix an issue with the recent Chrome 92 intervention that limits
the number of concurrent WebMediaPlayers (an inner element of
HTMLMediaElements) to 75/40.
Webcam video elements were being left dangling in paused state despite
the elements themselves being cleaned up from the component. That
generated a skewed accounting of WebMediaPlayers in the session.
Changes (maybe not a complete list):
- Disable virtualbgs by default
- Move the virtualbg selector in video-preview to the side below the
profile selection
- Restore old video-preview sizes
- Add a wrapper class for MediaStreams (BBBVideoStream)
- Centralize virtualbg services and business logic code into BBBVideoStream
- Refactor and centralize virtualbg constant fetching
- Refactor and centralize virtualbg config fetching
- Organize virtualbg type definitions
- Remove added states in video-provider to prevent further bloat
- Remove added states in video-preview to prevent further bloat
- Lock virtual bg switching while video-preview itself is locked
- Add proper virtualbg error surfacing via toasts
- Refactor iOS availability detection to use centralized UA checker
- Avoid calling gUM when toggling virtualbgs on/off
- Make virtualbg video-list-item action a toggle instead of a
state-aware action
- Make virtualbg switching work in video-preview for cameras that are
already shared. Especially useful when there are multiple source
cameras, and will be important in the near future
- Add Derivative Work notices in files that are partially copied from
jitsi-meet
- Simplify track replacing in video-provider
- Split video-preview UI code for virtualbgs into a separate functional component
