How to Subscribe

Subscribing to a Red5 Pro stream requires a few components to function fully.

Setup R5Connection

The R5Connection manages the connection that the stream utilizes. You will need to setup a configuration and intialize a new connection.

func getConfig()->R5Configuration{
	// Set up the configuration
	let config = R5Configuration()
	config.host = Testbed.getParameter("host") as! String
	config.port = Int32(Testbed.getParameter("port") as! Int)
	config.contextName = Testbed.getParameter("context") as! String
	config.`protocol` = 1;
	config.buffer_time = Testbed.getParameter("buffer_time") as! Float
	return config
}

BaseTest.swift #50

let config = getConfig()
// Set up the connection and stream
let connection = R5Connection(config: config)

SubscribeTest.swift #27

Setup R5Stream

The R5Stream handles both subscribing and publishing. Creating one simply requires the connection already created.

//Create our new stream that will utilize that connection
self.publishStream = R5Stream(connection: connection)
//Setup our listener to handle events from this stream
self.publishStream!.delegate = self

BaseTest.swift #75

The R5StreamDelegate that is assigned to the R5Stream will receive status events for that stream, including connecting, disconnecting, and errors.

Preview the Subscriber

The R5VideoViewController will present publishing streams as well as subscribed streams. To view the subscribing stream, it simply needs to attach the R5Stream.

A R5VideoViewController can be set on any UIViewController, or created programmatically

let r5View : R5VideoViewController = getNewR5VideoViewController(self.view.frame);
self.addChildViewController(r5View);

BaseTest.swift #121

To view the preview before publishing has started, use R5VideoViewController.showPreview.

view.addSubview(r5View.view)

r5View.showPreview(true)

r5View.showDebugInfo(true)

BaseTest.swift #121

Lastly, we attach the Stream to the R5VideoView to see the streaming content.

currentView?.attachStream(subscribeStream)

SubscribeTest.swift #34

Start Subscribing

The R5Stream.Subscribe method will establish the server connection and begin Subscribing.

self.subscribeStream!.play(Testbed.getParameter("stream1") as! String)
