Toggle Participant Media - Android

Control other participant's webcam and mic. For better idea, let's understand this with a real case scenario

Scenario 1 (Online Class) - In this scenario, the lecturer(Local Participant) will control the student's(Other Participant) webcam and mic as per his/her needs.

Scenario 2 (Online Events) - In this scenario, the event hosts will control the audience webcam and mic when someone wants to speak.

This guide will provide an overview of how to control other participant webcam and mic in a meeting.

1. Enable Webcam of Participant - By using enableWebcam() function, a onWebcamRequested event will trigger on requested participant side.

   Example : Meeting is running with User A and User B. Now User A wants to Enable Webcam of User B, so User A will use enableWebcam() function to request User B, after that User B recieve the onWebcamRequested event, from there user can either accept or reject the incoming request.

2. Disable Webcam of Participant - By using disableWebcam() function, webcam of that participant will be turned off.

   Example : User A wants to Disable Webcam of User B, so User A will use disableWebcam() function to Disable it without any request.

3. Enable Mic of Participant - By using enableMic() function, a onMicRequested event will trigger on requested participant side.

   Example : Meeting is running with User A and User B. Now User A wants to Enable Mic of User B, so User A will use enableMic() function to request User B, after that User B will receive the onMicRequested event, from there user can either accept or reject the incoming request.

4. Disable Mic of Participant - By using disableMic() function, Mic of that participant will disable.

   Example : User A wants to Disable Mic of User B, so User A will use disableMic() function to Disable it without any request.

note

To achieve this feature, you need to pass allow_join persmission while genearting token for meeting initialization. After that you will be able to access participant media methods.

How to apply permission while generating token?

Request Media Methods

Kotlin

val participant = meeting!!.participants.get("<participant-id>")

// This will emit an event called "onWebcamRequested" to that particular participant
participant.enableWebcam()

// This will directly disable webcam of particular participant
participant.disableWebcam()

// This will emit an event called "onMicRequested" to that particular participant
participant.enableMic()

// This will directly disable mic of particular participant
participant.disableMic()

Java

Participant participant = meeting.getParticipants().get("<participant-id>");

// This will emit an event called "onWebcamRequested" to that particular participant
participant.enableWebcam();

// This will directly disable webcam of particular participant
participant.disableWebcam();

// This will emit an event called "onMicRequested" to that particular participant
participant.enableMic();

// This will directly disable mic of particular participant
participant.disableMic();

Manage Requested Media Events

1. onWebcamRequested - This event will be emitted to the participant B when any other participant A requests to enable webcam of that participant B. This event handler will receieve following three arguments:

   • accept() - Callback function to accept the request.
   • reject() - Callback function to reject the request.

2. onMicRequested - This event will be emitted to the participant B when any other participant A requests to enable mic of that participant B. This event handler will receieve following three arguments:

   • accept() - Callback function to accept the request.
   • reject() - Callback function to reject the request.

Kotlin

object : MeetingEventListener() {
  override fun onMicRequested(participantId: String, listener: MicRequestListener) {
      // TODO: show dialog before accepting request
      listener.accept()
  }

  override fun onWebcamRequested(participantId: String, listener: WebcamRequestListener) {
      // TODO: show dialog before accepting request
      listener.accept()
  }
}

Java

new MeetingEventListener() {
  @Override
  public void onMicRequested(String participantId, MicRequestListener listener) {
      // TODO: show dialog before accepting request
      listener.accept();
  }

  @Override
  public void onWebcamRequested(String participantId, WebcamRequestListener listener) {
      // TODO: show dialog before accepting request
      listener.accept();
  }
}
