Other participants Map is used to get all the participants (except you) in the meeting at any given time.

Other participants Map contains same properties as LocalParticipant.

Local And Other Participants

/** localParticipant contains Participant object
as displayed above local participant section */
const localParticipant = meeting.localParticipant;

localParticipant.streams.forEach((stream) => {
setTrack(stream, videoElement, audioElement, participant.id);
});

const participants = meeting.participants;

/** to play other participants video & audio */
function loadOtherParticipants() {
meeting.participants.forEach((participant) => {
let videoElement = createVideoElement(participant.id);
let audioElement = createAudioElement(participant.id);

participant.streams.forEach((stream) => {
setTrack(stream, videoElement, audioElement, participant.id);
});

videoContainer.appendChild(videoElement);
videoContainer.appendChild(audioElement);
});
}

// creating video element
function createVideoElement(pId) {
let videoElement = document.createElement("video");
videoElement.setAttribute("id", `v-${pId}`);
return videoElement;
}

// creating audio element
function createAudioElement(pId) {

.play()
.catch((error) =>
console.error("videoElem.current.play() failed", error)

}
}
  1. participant-joined - Whenever any new participant join the meeting, participant-joined event will trigger. For example, the meeting is running with Alice and Bob, then Eve join that meeting, after that participant-joined event trigger and return the participant object.

  2. participant-left - Whenever any participant leave/exit the meeting, participant-left event will trigger.For example, the meeting is running with Alice and Bob, then Bob leave that meeting, after that participant-left event trigger and return the participant object

  3. presenter-changed - Whenever any participant present/screenshare their screen/window in meeting, presenter-changed event will trigger and return the presenter participantId.

  4. stream-enabled - Whenever any participant enabled mic/webcam in meeting, stream-enabled event will trigger and return Stream Map.

  5. stream-disabled - Whenever any participant disabled mic/webcam in meeting, stream-disabled event will trigger and return Stream Map.
