* ref(JitsiConference) Remove remote tracks from conf before reneg is done. We do not have to wait for the removal of the ssrcs from the remote description for removing the remote tracks associated with a participant that left the call. This speeds up removal of the participant from call even if the JingleSession modification queue is backed up.
* faet(SDP): Add test for jingle JSON format.
42c675249a...111e50c38a
* ref(JingleSessionPC) Do not renegotiate on every local source change. Instead rely on the 'negotiationneeded' event fired by the browser for JVB connection. This makes local source changes faster even if the modification queue is backed up.
75d3106544...012c38769d
* 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.

* fix(JitsiConference) Check for room before calling isFocus method on the room object.
* fix(Jingle) Reverse the order of ssrcs signaled for Firefox. This fixes an issue where the bridge doesn't forward the HD stream from Firefox to other users in the call. The order of the ssrcs produced by the browser is from Highest resolution to lowest whereas the bridge assumes it to be from lowest to highest as is the case in Chrome and Safari.
* fix(codec-selection): Impose VP9 bitrates only when VP9 is the negotiated codec. If Jicofo doesn't offer VP9 but the client expresses a preference for VP9, VP9 bitrates were being imposed before.

When participants panel is open and we approve a participant to unmute, the notification was not hidden as we were not correctly updating the state. We were expecting a participant object, but an id of the participant was used.
* fix(ConnectionQuality): Do not show red/yellow GSM bars on join. When the user first unmutes their video, the connection quality is shown as poor until the local stats are available. Calculate the connection quality only after the stats are available, i.e., assume 100% until pcStatsInterval has elapsed.
* feat(non-participant-messages) Add a new JitiConferenceEvent for messages ignored by ENDPOINT_MESSAGE_RECEIVED
* fix(precall) respect custom callstats script url for precall test
9e632a77c5...6a3df11ffa
* feat(BridgeChannel): Signal a new videoType for high fps screenshare. This lets the bridge adjust the bitrate allocation for this source so that layers with higher fps are prioritized over layers with higher resolution. As a result, endpoints with restricted downlink will receive a high fps low resolution share as opposed to a high resolution low fps screenshare.
* fix(log) lower severity of overly verbose logs (2)

THe new version fixed a longstanding problem with RN not updating the JS side
SDP representation properly. This will allow us to remove a hack we currently
have to sidestep this.
* feat(JingleSessionPC): Enable unfied plan by default for chrome p2p.
* fix(JingleSessionPC): Fix startMuted cases for p2p unified plan. Chrome doesn't create a decoder for ssrc in the remote description when there is no local source and the endpoint is offerer. Initiating a renegotiation with the endpoint as a responder fixes this issue. Add a workaround until Chrome fixes this bug.
* fix: Missed SSRCs in Unified Plan with several "ssrc-group:FID" groups. (#1658)
e6648fac96...b815157a22
* fix(TPC): Fix the screenshare issue when user starts video muted on chrome. Munge 3 ssrcs in the SDP for chrome in unified plan always for the simulcast case.
053a26604d...e6648fac96
* fix(JingleSessionPC): Disable unified-plan for p2p chrome. Do not enable unified plan for p2p chrome by default until StartMutedTest is fixed. Fix media direction for case when there are no local and remote sources, should be set to 'inactive' in that case.
3a313a244d...053a26604d
* fix(codec-selection): Fix VP9 codec switching issue in Chrome unified-plan. Munge only the m-line that corresponds to the source that the browser will be sending. Do not select VP9 on Firefox. Detect support for RTCRtpTransceiver#setCodecPreferences correctly.
89a7e2d9cd...3a313a244d
* fix(RTC): In unified-plan mode, disable the low resolution streams for low fps SS. In unified plan impl, it is not possible to enable/disable simulcast during the call since the same sender is re-used for all local video tracks. Therefore, disable the low resolution simulcast streams for low fps screensharing so that the bridge forwards only the highest resolution stream which is important for low fps screensharing.
f974007ca6...89a7e2d9cd
* fix(JingleSessionPC): Do not check if the ssrc already exists in the RD when adding a ssrc-group from source-add.
* feat: Switch to unified plan on chrome by default unless explicitly disabled.
* fix(VADAudioAnalyser): NPE error evaluating this._vadEmitter.on (#1652)
* Small fix in tokens doc.
b43a9fa0ee...f974007ca6
* fix(TPC): Do not remove ssrcs from remote desc for p2p. In unified plan, re-use of m-line (i.e., adding an SSRC, removing it and then adding it back) causes the browser to not render the media on Chrome and Safari. The WebRTC spec is not clear as to how browsers have to behave, this doesn't cause any issues on Firefox. As a workaround, only change the media direction and leave the ssrc in the remote desc. This automatically triggers a 'removetrack' event on the associated MediaStream and the track can be removed from the UI.
* Drops old prosody versions from the tokens instructions
0cdfb79c2e...b43a9fa0ee
* squash: Set capScreenShareBitrate flag every time a new pc is created.
* feat(RTC): Add the ability to change desktop share fps. Provide a method for changing the capture fps for desktop tracks during the call. These changes to the lib are needed for making it configurable from the UI.
46ec23fcdc...229015a6f3
* fix(RTC): Do not overwrite other constraints when resolution option is used. When the resolution option was being used, all the other constraints like frameRate and facing mode were being overwritten.
24627e1b95...46ec23fcdc
* fix(TPC): Filter ssrcs differently while extracting the SSRC map from SDP. Use 'msid' for plan-b clients and 'cname' for unified-plan clients.
fad985e95a...d5e60583b8
* fix(TPC): fix local resolution/fps stats. Browsers do not generate a 'msid' attribute for ssrcs in unified plan mode, use mediaType as a key for the TrackSSRCInfo map.
* fix(recording): Send participant id when recording starts/stops (#1632)
8057f12a39...2259d44185
* fix(RTC): Adjust the media direction for p2p conn. For p2p connections, the media direction needs to be adjusted after every source-add/source-remove is processed based on the availability of local sources.
* fix(RTC): Use a enum for media direction.
5738c80baf...d9d9b7fc31
* fix(JingleSessionPC): Disable unified-plan for p2p. Disable cross browser p2p using unified plan until all the issues are fixed.
0993c8e93d...5738c80baf
* fix(LocalSdpMunger): Fix unit test.
* fix(CodecSelection): Call RTCRtpTransceiver#setCodecPreferences before renegotiation. Call RTCRtpTransceiver#setCodecPreferences with the preferrred codec order before every createOffer/createAnswer. This ensures that the codec preference is enforced even when there is no local description available yet while the preferred codec is being set immediately after media session creation.
* fix(JingleSessionPC): Add a workaround for chrome issue. The 'signalingstatechange' event for 'stable' is fired after the 'iceconnectionstatechange' event for 'completed' is fired on chrome in Unified plan. This prevents the client from switching the media connection to the p2p connection once the ice connection for p2p gets established.
* fix(Logging): Log enhancements. Add a preifx to logs for idenitifying the type of TPC/jingleSessionPC.
* feat(TPC): Enable unified-plan support for Chromium based browsers. This can be controlled through the config.js option 'enableUnifiedOnChrome'.
* fix(TPC): Do not configure encodings on Safari until reneg. Avoid configuring the encodings on Chromium/Safari until simulcast is configured for the newly added track using SDP munging which happens during the renegotiation.
* fix(TPC): Do not configure encodings on chromium immediately after replace track. Avoid configuring the encodings on chromium immediately after replace track since the encoding params are read-only until the renegotation is done.
* fix: send json message (#1180)
be3e2a69f2...3fb44f7695
* fix(SDP): Add missing msid for p2p sources.
* fix(TPC): Don't convert plan-b<->unified-plan SDPs for p2p.
* squash: Implement review comments.
* fix(JingleSessionPC): Do not try to re-use inactive mid for new remote ssrcs. The direction was marked as 'inactive' only on Firefox as Safari had audio issues when an inactive mid is re-used. Chrome (in unified-plan) needs the direction of the mid in remote desc to be set to 'inactive' for a 'removetrack' to be fired on the associated media stream whenever a remote source is removed.
* fix(SDP): Drop SSRCs whenever the transceiver direction is 'inactive' or 'recvonly'. This is needed only for JVB connections. Add unit tests for LocalSdpMunger.
* fix: Ignore startAudioMuted/startVideoMuted for p2p. The tracks will not be added when the call switches from jvb to p2p for an endpoint that joins muted by focus.
* fix(RTC): Do not suppress the source updates on Firefox. If the msid attribute is missing, then remove the ssrc from the transformed description so that a source-remove is signaled to Jicofo. This happens when the direction of the transceiver (or m-line) is set to 'inactive' or 'recvonly' on Firefox. Not signaling these source updates creates issues with remote track handling on the other endpoints in the call.
* fix(RTC): Set transceiver direction after RTCRtpSender#replaceTrack. This fixes the issue where TRACK_REMOVED event is not fired when a remote track is removed from the peerconnection. Fixes https://github.com/jitsi/lib-jitsi-meet/issues/1612 and https://github.com/jitsi/jitsi-meet/issues/8482.

Add the ability to configure different max bitrates for VP8 and VP9.
Set max bitrate for presenter to 2500 Kbps irrespective of the configured max bitrates for video.
479dd98...77978f0.
RN doesn't support RTCRtpSender yet. Therefore, media is suspended on RN by changing the media direction in the SDP whenever the client receives an ideal height of 0 for sender constraints on the bridge channel.
LJM update - 3570339360...be18ff34be.
When an endpoint that doesn't support the preferred codec (VP9) joins a conference, all the other endpoints fallback to VP8 until the endpoint leaves the call.
Safari 14.1 has a bug where it returns 720p for every simulcast stream when RTCRtpSender.getParameters is called even though the stream resolutions are different.
By using the encodings config used when source was added, on every RTCRtpSender.setParameters call, we ensure that simulcast stream resolutions don't change.
chore(deps) lib-jitsi-meet@latest
Do not resize the desktop share to 720p by default when the desktop track resolution is higher than 720p. This is causing bluriness when presenter is turned on.
Remove the 'detail' contentHint setting for the desktop+presenter canvas stream as it forcing chrome to send only 5 fps stream for high resolution desktop tracks.
Move the desktop resizing logic behind a config.js option - videoQuality.resizeDesktopForPresenter.
