Firefox lists stopped transceivers when getTranceivers is called, ignore these when picking a trancceiver for a screenshare track. Fixes an issue when starting screenshare fails if there are stopped tranceivers in the peerconnection (i.e., if some remote users with sources have left the call).

Fixes cases where SS fails in multi-stream mode with p2p->jvb->p2p switching.

In Unified-plan mode, we rely on the browser to fire 'negotiationneeded' event to start a O/A cycle. Also add muted tracks to PC. Fixes issues where the streams are not being signaled when call switches over from p2p to jvb in multi-stream mode.

Fixes cases where SS stream is not being sent when p2p->jvb switch happens.

> Possibly fixes a bug where SS appears black when the'unmute' and forwarded sources event for the track are received before a large-video update is scheduled.

This fixes an issue where the bitrates for screenshare were much higher than before for VP9 causing the JVB to suspend SS streams more often.

It does no harm on RN, since it doesn't detect it as a supported browser
and bails out.

It gets resolved during translation.

Since Track effects and mute/unmute operations use the same flow, i.e., removing/adding the track from the RTCPeerConnection but not from TPC, make the names of the methods involved more generic.

Since the track is only temporarily removed and added back, it can be treated like mute & unmute operation. Fixes https://github.com/jitsi/lib-jitsi-meet/issues/2048. Remove a TODO thats no longer needed, track replace operation don't force renegotiations anymore.

* feat: Add videoType to sources signaled in jingle.

Set the bitrates on the video m-lines based on the associated track type. In multi-stream mode, there will be two separate m-lines for camera and desktop tracks. Also fallback to SDP munging for setting codec preferences on Chromium.

The hack for making Chrome capture the highest resolution possible for desktop track breaks high fps screen capture.

Jicofo by default now strips the simulcast SSRCs and sends only the primary SSRC and RTX to all the receiving endpoints in the call. Therefore remote SDP munging is not required on the clients anymore.

They have been deprecated and their valued can no longer be changed from
the default after M103.

This reverts commit 7d3f13c907.
This change was not needed.

RN clients throw a function undefined error otherwise.

When source-name signaling is enabbled on plan-b clients, the sources to MSID map needs to be cleared after every transformation since browser in plan-b mode produces a new set of SSRCs and trackID when a track is removed and new track is added to the peerconnection. This fixes an issue where the track index in the source-name gets incremented after a track replace operation.

* fix(multi-stream): Fix local SSRC cache to include multiple video streams.
If multiple local video streams are found in the SDP, cache all of them instead of the first video SSRC. This fixes an issue where the resolution/fps stats for the screenshare track are not available.

* squash: new track inherits the source name of old track if it exists.

* fix(rtc): fix local track removeTrack promise conference check

* ref: ignore if promise was successful or not

Enables lite mode which disables any media decoding.

* feat: Add an option to set bogus resolution constraints for getDisplayMedia.

With https://bugs.webkit.org/show_bug.cgi?id=179363 being fixed, we should now be able to switch between devices in call.

* fix(video-quality) Update frame heights in content-modify for p2p.
When the user changes the preferred video quality settings from the UI, update the frame height values in content-modify for p2p connection when source-name signaling is enabled.

* fix(multi-stream) Send presence for desktop track before signaling when it is the first track to be added to the conference.
Also do not suppress renegotiation for desktop track on p2p since the browser doesn't fire negotiation needed event.

* squash: fix build

* squash: fix linter issues

* squash: add comment.

This fixes an issue where the receiver constraints and video type messages are sent on the bridge channel only the first time the ws conn gets re-established.

When source-name signaling is enabled, get correct peermedia info when the peer sends presence in the legacy format. This fixes an issue where Jigasi users cannot be heard by endpoints that have source-name signaling enabled.

* fix(multi-stream) add new m-line when remote adds a second video source in p2p.
A new m-line needs to be added in the remote description when a new secondary video source is signaled by the peer.

* fix(TPC) Suppress lower layers only for screenshare tracks.
With multi-stream support enabled, an extra check for videoType for local track is needed to dtermine if the lower layers need to be suppressed.

* fix(TPC) Mark the direction inactive on inactive media connection.
If a new secondary video source is added on the jvb connection while p2p is active, make sure the direction is set to inactive on the jvb connection, so that no media is being sent out on the jvb connection.

* squash: Address review comments.

Handle presence updates for multiple sources per remote endpoint.

Also switch to using signalingLayer.getPeerSourceInfo during remote track creation when source-name signaling is used.

This is needed for the track to be identified as a desktop track on the remote peer when the JitsiRemoteTrack is created.
Fixes https://github.com/jitsi/lib-jitsi-meet/issues/1649.

Fixes an issue where the local stats are not emitted in Unified plan after a track replace.

* fix(multi-stream-support) Support muting of desktop track.

* fix(multi-stream) Always initiate responder renegotiation even for p2p.
This is needed since the new m-line is always added to the remote description.

* fix(multi-stream) Support multi-stream only on Unfied plan endpoints.

* fix(multi-stream) Advertise source-name signaling to Jicofo when supported.

* fix(JitsiLocalTrack): Remove unnecessary reject.

* fix: add the correct source name attribute for the second video track.

* squash: Address review comments.

Chrome doesn't render media when the SSRC is added back to the m-line after removing it because of source-remove->source-add from peer. Avoid renegotiations so that these source removes and adds are not sent to the peer after the track is replaced.

This fixes an issue where replaceTrack fails when a muted track is being replaced with another track in Unified plan.
