A class defining the spec paramter in the createStream method.

Create a Stream

You have two options to create an audio/video stream:

Set the audio, video, and screen properties

var stream = AgoraRTC.createStream({
  streamID: uid,
  audio:true,
  video:true,
  screen:false
});

Set the audioSource and videoSource properties

Compared with the first option, the audioSource and videoSource properties can specify the audio and video tracks for the stream. Use this option if you need to process the audio and video before creating the stream.

Use the mediaStream method to get the audio and video tracks from MediaStreamTrack, and then set audioSource and videoSource:

navigator.mediaDevices.getUserMedia(
    {video: true, audio: true}
).then(function(mediaStream){
    var videoSource = mediaStream.getVideoTracks()[0];
    var audioSource = mediaStream.getAudioTracks()[0];
    // After processing videoSource and audioSource
    var localStream = AgoraRTC.createStream({
        videoSource: videoSource,
        audioSource: audioSource
    });
    localStream.init(function(){
        client.publish(localStream, function(e){
            //...
        });
    });
});

Note:

• MediaStreamTrack refers to the MediaStreamTrack object supported by the browser. See MediaStreamTrack API for details.

• Currently this option only supports the Chrome brower.

Enable Screen-sharing on the Chrome Web Browser

var stream = AgoraRTC.createStream({
  streamID: uid,
  audio:false,
  video:false,
  screen:true,
  extensionId:"minllpmhdgpndnkomcoccfekfegnlikg"});

Enable Screen-sharing on the Firefox Web Browser

localStream = AgoraRTC.createStream({
     streamID: uid,
     audio: false,
     video: false,
     screen: true,
     mediaSource: "screen",
   });

For a tutorial on screen-sharing on a website, see Advanced: Screen Sharing on the Web.

Note:

• Do not set video and screen as true at the same time.

• To enable screen-sharing on the Firefox browser, ensure that the screen property is set to true, and the mediaSource property has been set to specify a certain sharing mode.
