Publish to Session

To publish a stream, User B uses the Session.publish method:

User B publishes a stream; User A is notified that User B has published a stream

The Session.publish() method starts publishing an audio/video stream to the session, and displays the video being streamed on the local web page as directed in the method invocation.

The session sends a streamCreated event to all connections. The event object for this event is of type StreamEvent. The StreamEvent object includes an array of Streams.

Through this event, User A's web page can learn that User B has started publishing a stream, and can choose to subscribe to it as shown in the next workflow.

Note that User B's web page is also notified of the stream they are now publishing. User B's web page can know that a streamCreatedEvent references its own published stream by comparing the new stream's connection.connectionId property to its own connection ID. In most cases, User B's web page will choose to ignore the notification.

In OpenTok v0.91.5, you can restrict users from publishing to a session. Users in the subscriber role can only subcribe to streams in a session (they cannot publish). For more information, see Connection Token Creation.

Next workflow step: Subscribe to a stream.
