About Flash Communication Server 21

3 Create a connection function that connects to the Flash Communication Server, displays a

trace message indicating whether the connection was successful, and opens and instance of the

doc_connect application named room_01. Remember, you must specify the Real-Time

Messaging Protocol,

rtmp.

function doConnect() {

client_nc = new netConnection();

client_nc.onStatus = function(info) {

trace("Level: " + info.level + " Code: " + info.code);

}

client_nc.connect("rtmp://localhost/doc_connect/room_01");

}

Note: If your SWF is on the same computer that is running the Flash Communication Server, you can use

rtmp:/doc_connect/test as a shortcut version of rtmp://localhost/doc_connect/test. This usage indicates a

relative path and lets you move the files to a different server without changing the code. Also, remember that if

you aren’t using the Flash MX authoring environment on the computer that is running the Flash Communication

Server, substitute your server URL for “localhost”.

4 Create a function to publish the video by creating a network stream out_ns, attaching the

camera to that stream, and then publishing the stream as

myTestStream.

function publishMe() {

out_ns = new netStream(_root.client_nc);

out_ns.attachVideo(client_cam);

out_ns.publish("myTestStream");

}

Note: The statement out_ns.publish("myTestStream") omits the optional parameter howToPublish.

When this parameter is missing, the server automatically publishes the stream as live (that is, the stream is not

recorded while it is being published).

5 Create a function to play the published stream by creating a second network stream in_ns,

attaching the contents of that stream to the Published_video video object, and then playing

the stream named

myTestStream that is being published by the server.

function playMe() {

in_ns = new netStream(_root.client_nc);

Published_video.attachVideo(in_ns);

in_ns.play("myTestStream");

}

Write the commands to call the functions you just created.

// Connect to the server

doConnect();

// Publish the live stream

publishMe();

// Play back the stream from the server

playMe();

Save the file.
