WebRTC Conference Call

Ant Media Server offers robust support for conference calls. In this tutorial, we will see how to use the Basic Conference sample page. If you are looking for a ready-to-use conference solution, please check out our in-house Circle Conference tool with all necessary features.

Conference Call Sample Page

Go to https://your-domain-name:5443/live/conference.html for conference call sample page.

The WebRTC conference feature is only available in the Enterprise Edition of Ant Media Server

If you have Ant Media Server installed on your local machine, you can also go to http://localhost:5080/live/conference.html.

Click on Join Room the button, then open the same web page on multiple tabs or multiple systems and join from there. Now you will start to receive the streams of remote participants.

Join Conference Room

When WebRTCAdaptor is initialized successfully, it creates a websocket connection. After a successful connection, the client gets the initialized notification from the server. After receiving initialized notification, we can start publishing and playing to the conference room.

Think of the conference room this way: we will publish our video streams and we will play the videos of the remote participants, so essentially we will be using the same publish and play functions we normally use for publishing and playing streams.

Just call the publish method as follows:

publish(streamId, token, subscriberId, subscriberCode, streamName, mainTrack, metaData, role) 

• streamId (mandatory): ID of the stream.

• mainTrack (mandatory): ID of the room that the stream will be published to.

For example, if we are joining theroom1 conference room, then room1 is the mainTrack.

Play Conference Room Stream

In order to play remote streams from the room, call the play method.

In a conference call, the correct place to call the method is when joinedTheRoom and roomInformation notifications are received. Play Method should be called with the correct roomId that needs to be played.

play(streamId, token, roomId);

• streamId (mandatory): ID of the stream that needs to play.

• roomId (mandatory): ID of the room that needs to play.

Turn Camera On/Off

• To turn off the camera, call the turnOffLocalCamera method.

  webRTCAdaptor.turnOffLocalCamera(streamId);

• If your camera is turned off, call turnOnLocalCamera to turn it on.

  webRTCAdaptor.turnOnLocalCamera(streamId);

Mute and Unmute Microphone

• Call muteLocalMic to mute the microphone.

  webRTCAdaptor.muteLocalMic();

• To unmute, call unmuteLocalMic.

  webRTCAdaptor.unmuteLocalMic();

These methods don't take any parameters.

Server Notifications

Here are the conference-related notifications that callback is invoked for. Please check the conference.html for proper usage.

• newStreamAvailable: Called when a previously joined stream is ready to play.
• publish_started: Called when stream is published to the room.
• play_started: Called when starting to play the remote streams.
