Cleans up WebRTCEndpoint instance.
Tries to connect to the RTC Engine. If user is successfully connected then WebRTCEndpointEvents.connected will be emitted.
Any information that other endpoints will receive in WebRTCEndpointEvents.endpointAdded after accepting this endpoint
OptionalconnectionDisables track encoding so that it will be no longer sent to the server.
Disconnects from the room. This function should be called when user disconnects from the room
in a clean way e.g. by clicking a dedicated, custom button disconnect.
As a result there will be generated one more media event that should be
sent to the RTC Engine. Thanks to it each other endpoint will be notified
that endpoint was removed in WebRTCEndpointEvents.endpointRemoved,
Enables track encoding so that it will be sent to the server.
Feeds media event received from RTC Engine to WebRTCEndpoint. This function should be called whenever some media event from RTC Engine was received and can result in WebRTCEndpoint generating some other media events.
String data received over custom signalling layer.
This example assumes phoenix channels as signalling layer. As phoenix channels require objects, RTC Engine encapsulates binary data into map with one field that is converted to object with one field on the TS side.
webrtcChannel.on("mediaEvent", (event) => webrtc.receiveMediaEvent(event.data));
Updates the metadata for the current endpoint.
Data about this endpoint that other endpoints will receive upon being added.
If the metadata is different from what is already tracked in the room, the optional
event endpointUpdated will be emitted for other endpoint in the room.
Updates the metadata for a specific track.
trackId (generated in addTrack) of audio or video track.
Data about this track that other endpoint will receive upon being added.
If the metadata is different from what is already tracked in the room, the optional
event trackUpdated will be emitted for other endpoints in the room.
Adds track that will be sent to the RTC Engine.
Audio or video track e.g. from your microphone or camera.
OptionaltrackMetadata: unknownAny information about this track that other endpoints will receive in WebRTCEndpointEvents.endpointAdded. E.g. this can source of the track - whether it's screensharing, webcam or some other media device.
OptionalsimulcastConfig: SimulcastConfigSimulcast configuration. By default simulcast is disabled. For more information refer to SimulcastConfig.
OptionalmaxBandwidth: TrackBandwidthLimitmaximal bandwidth this track can use. Defaults to 0 which is unlimited. This option has no effect for simulcast and audio tracks. For simulcast tracks use `WebRTCEndpoint.setTrackBandwidth.

Updates maximum bandwidth for the given simulcast encoding of the given track.
id of the track
rid of the encoding
desired max bandwidth used by the encoding (in kbps)
Sets track variant that server should send to the client library.
The variant will be sent whenever it is available. If chosen variant is temporarily unavailable, some other variant will be sent until the chosen variant becomes active again.
id of track
variant to receive
Updates maximum bandwidth for the track identified by trackId. This value directly translates to quality of the stream and, in case of video, to the amount of RTP packets being sent. In case trackId points at the simulcast track bandwidth is split between all of the variant streams proportionally to their resolution.

success
Main class that is responsible for connecting to the RTC Engine, sending and receiving media.
