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.

This is needed only for JVB connections. Add unit tests for LocalSdpMunger.

The tracks will not be added when the call switches from jvb to p2p for an endpoint that joins muted by focus.

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.

This fixes the issue where TRACK_REMOVED event is not fired when a remote track is removed from the peerconnection.

There is a known issue with Firefox where the BWE gets halved on every renegotiation causing the low upload bitrates from the Firefox clients.

When a msid attribute is missing in the 'a=ssrc' line, use the local endpoint id as an indentifier. Move this generation logic to LocalSdpMunger. Also suppress notifying Jicfo of a ssrc change on Firefox when the change is a result of the media being suspended on the jvb connection.

Get rid of noisy logs related to SDP transformations which are redundant. Fix formatting and add missing information.

If the application is using the new receiver constraints, propagate the height constraint to the p2p session as well.

Do not send old format constraints if no constraints are set before the channel is initialized.

It dropped Edge support so we get 30K back!

In certain cases, when RTCPeerconnection#addTrack is used, the browser doesn't produce the streamid in the 'a=msid' line which is being used by Jicofo as a unique identifier for the associated ssrc. Whenever the msid is missing in the local description, generate an ID using the local endpoint id.

Older chrome versions like M72 do not support Promise.allSettled.

Do not try to configure encodings on the sender until they are available. This fixes an issue on Chrome (running in unified-plan mode) where unmuting the local source throws a 'Read-only field modified in setParameters()' error.

SDP utility classes are spread across RTC and XMPP directories now, moving these class files to a 'sdp' directory.

Switch to returning a Promise for getStats. Reset frame rate stat to 0 when video is suspended as a result of endpoint falling out of last-n.

* Fix: sysMessageHandler not deleted

#1589

* Update xmpp.js

Fixes the case where the old format height constraint is sent on join for a jvb media session.

Use the new receiver constraints unless it is explicitly disabled through config.js.

Drops the custom type breaking xmpp protocol.

* fix: high CPU on Chrome with low fps screen sharing

It turns out that if 5 fps is set on the track constraints,
Chrome will capture the original video in 30 fps and only
further down the pipeline will downsample it to 5 fps.
This results in very high CPU usage. Specify max FPS in
getDisplayMedia to fix the problem.

Getting rid of track.applyConstraints should also fix another
issue on Firefox where it reports 0x0 screen size after this call.

* ref(RTCUtils): remove trackOptions

* remove extra &&

This will reduce the numbers of transport-info IQs sent by the client.

Get rid of the browser specific keys and use the standard spec-compliant fields for stats.
Get the resolution/fps for remote streams from 'inbound-rtp' stats. Use the 'track' stats for the local resolution/fps since these take the active simulcast streams into account.
