Publishing a Stream to the Session

When the app connects to the Vonage Video session, we want it to publish an audio-video stream to the session, using the camera and microphone:

1. Add a Publisher member variable to the MainWindow class (after the declaration of the Session member variable):

Publisher Publisher; 

The Publisher class is defined in the Vonage Video Windows SDK.

2. Modify the MainWindow() constructor to include code to initialize a video capturer for the publisher and use that video capturer in a Publisher object:

Publisher = new Publisher(Context.Instance, renderer: PublisherVideo);

The code uses the Publisher() constructor to instantiate a Publisher object. Two parameters are passed into the constructor: the Windows application context and the video renderer (defined in the MainApplication.xaml file).

3. Modify the Session_Connected() method to include code to publish a stream to the session:

private void Session_Connected(object sender, System.EventArgs e)
{
    Session.Publish(Publisher);
}

When the application connects to the session (and the SessionConnected event is raised) the Session_Connected event handler calls the Session.Publish() method, passing in the Publisher object. This causes the app to publish an audio-video stream to the Vonage Video session, using the video capturer's microphone and camera as the audio source and video source.

Debug your application. The app displays the local video preview of the publisher and, when the app successfully connects to the Vonage Video session, it publishes a stream to the session.
