* fix: Drop duplicate call of wait for owner.

* fix: Fixes leaking listeners while waiting for host to join.

While waiting for the host to join on the dialog we attempt to join over and over again till we are admitted to enter the meeting. While doing that authRequired flag is on, and we were adding listeners on and on.

* feat: Introduces conference join in progress action.

This event is coming from lib-jitsi-meet and is fired when we receive the first presence of series when joining. It is always fired before joined event.

In audio-only screenshare mode when there is no local audio track from mic present, do not add the audio track from screenshare to redux. Adding the track to redux will sync the track mute state to that of /base/media and show that the mic is unmuted even when that is not the case. Fixes https://github.com/jitsi/jitsi-meet/issues/10706.

This workaround is not needed anymore since P2P is disabled between plan-b and unified-plan clients.
Fixes https://github.com/jitsi/jitsi-meet/issues/11131

This reverts commit c30038236a.

* feat(multi-stream-support) Add screenshare as a second video track to the call.
This feature is behind a sendMultipleVideoStreams config.js flag. sourceNameSignaling flag also needs to enabled. Sending multiple tracks is currently supported only on endpoints running in unified plan mode. However, clients with source-name signaling enabled and running in plan-b can still receive multiple streams .

* squash: check if there is an existing track before adding camera/desktop

* squash: enable multi-stream only on unified plan endpoints.

Make the behavior consistent with enabling camera when the user is audio-only mode. Also fixes an issue where the screenshare preview doesn't appear if it is enabled while the user is in audio-only mode.

* feat(lobby): lobby chat

lobby chat support
knocking participants list updates
knocking participants conditonal checks to show message button
handle lobby chat message events
lobby messages from or to moderators only

This is a follow up for https://github.com/jitsi/lib-jitsi-meet/pull/1944. This is needed to avoid sending a soure-remove followed by a source-add for the same ssrc. This happens when a users mutes camera->starts SS->stops SS->turns on camera on a p2p connection in Unified plan mode. Chrome fails to render the media if the same SSRC is removed and added back to the same m-line.

This is already supported on mobile. The user is allowed to enable their video in audioOnly mode so it doesn't make sense to block screenshare.

* feat: Handles hidden-from-recorder from jwt.

Hides the participant that has this flag in jwt from the recorder. A hidden meeting moderator.
Makes sure follows me works and no tracks are being added.

* squash: Skips showing notification when disabling
local audio and video.

* squash: Fixes comments.

* squash: Updates with ljm changes.

When Jibri counts the participants in the meeting other Jibris should
not be accounted for.

Added config to choose between recording and always mode
Created function to check if feature should be used
Removed check from stop feature as it now checks if the feature was previously on
Only get video track on feature start

This is no longer supported as per the w3c spec for getDisplayMedia.

In case of slow resolving gUM, we can join the call (quickly joining from pre-join screen) and the gUM will be resolved after we receive the start A/V muted from jicofo and will produce a source-add, joining unmuted ignoring jicofo.

When gUM is slow, and we quickly join the conference, then startWithAudioMuted was not respected.

dekstopAudioStream --> desktopAudioStream

Only audio and video are considered. Screen sharing won't be preserved.

* feat(tracks) Clean up the track if a source addition is rejected.
When jicofo rejects a source-add because of sendder limits, dispose and remove the local track from the conference.

* chore(deps) update LJM to latest.

* fix(screenshot-capture) Update screenshot capture feature

Add participants jid list to request

Enable screenshot capture only when recording is also on

Updated interval

This fixes an issue where the user muted by focus is able to unmute themselves even when the sender limit has been reached.

Not all code paths return a Promise, make sure it does.

* feat(conference) Impl audio/video mute disable when sender limit is reached.
Jicofo sends a presence when the audio/video sender limit is reached in the conference. The client can then proceed to disable the audio and video mute buttons when this occurs.

* squash: use a different action type and show notification.

Re-create local tracks so we have a clean state.

Unify the 2 functions used to leave the room into a single one.

Went for a different approach, this code is dead now.

- implement breakout-rooms
- integrated into the participants panel
- managed by moderators
- moderators can send participants to breakout-rooms
- participants can join breakout rooms by themselve
- participants can leave breakout rooms anytime

There are hard to handle race conditions around
screensharing/presenter mode turning on/off. It's
easier to make a NO-OP for turning the camera on/off
while switching to screen sharing is in progress
than trying to handle this gracefully. It should be okay
for the user to click the button again after the switch
operation is done.

Ideally this logic will be re-implemented in redux
middlewares and moved out of the conference.js file.

* fix(conference) avoid double prompts in Firefox after choosing non-default device

* addressed linting errors

Send screenshare duration to analytics

* feat: Hides prejoin screen on conference in progress event.

We enter the conference view as early as possible on conference in progress as the joined event can be late in a big conference.
Also, we show conference view only when joining is in progress, for example, the with the lobby enabled where we try to join but fail, we do not want to show the conference view for a fraction of a second before showing lobby screen.

* squash: Drops CONFERENCE_JOIN_IN_PROGRESS.

* squash: Updates ljm with the new JitsiConference event.

* squash: Adds some debugs to the github action.

Easier to catch problems with package-lock.json file.

This fixes an issue where Safari users cannot hear remote audio if they join audio/video muted. The browser throws the following error when the application tries to execute play on the audio element: 'NotAllowedError: The request is not allowed by the user agent or the platform in the current context, possibly because the user denied permission.' This started happening in Safari 15.

Changed screen capture to non effect. Effects are used to alter the stream, this feature does not need to alter the stream, it just needs access to it

Changed image diff library. Previous library diff’ed the whole image, the new one has en early return threshold

Use ImageCaptureAPI to take the screenshot. Added polyfill for it and polyfill for createImageBitmap

Added analytics

Stop everyone's video now also stops screensharing for the moderator that did the action, not just video

* Update moderation in effect notifications

Only display one notification for each media type. Display notification for keyboard shortcuts as well

* Update muted remotely notification

Display name of moderator in the notification

* Fix indentation on moderation menu

* Update text for video moderation

* Added moderator label in participant pane

* Update microphone icon in participant list

For participants that speak, or are noisy, but aren't dominant speaker, the icon in the participant list will look the same as the dominant speaker icon but will not change their position in the list

* Added sound for asked to unmute notification

* Code review changes

* Code review changes

Use simple var instead of function for audio media state

* Move constants to constants file

* Moved constants from notifications to av-moderation

* do not use this.local video

* move tracks initialized flag around

* do not use this.localAudio

* untangle use audio/video stream methods

It should be safe to call setVideoMuteStatus and
setAudioMuteStatus regardless of the prejoin page
visibility state.

* add NO-OP to use track methods and fix crash
in _setLocalAudioVideoStreams on not a promise

* use allSettled

On mobile Safari, when a user joins both audio and video muted, browser doesn't playout the remote audio because of a webkit bug. As a workaround, always add the audio track to peerconnection and then mute the track if needed.

* feat(Filmstrip): Reorder the visible participants in the filmstrip.
The participants are ordered alphabetically and the endpoints with screenshares, shared-videos and dominant speakers (in that order) are bumped to the top of the list. The local participant is also moved to the top left corner as opposed to the bottom right corner.

* squash: Implement review comments.

* squash: store alphabetically sorted list in redux and move shared videos to top.

* squash: Use the DEFAULT_REMOTE_DISPLAY_NAME from interfaceConfig for users without a display name.
