Client-Side Communication ActionScript 75

• If you pass "append" for howToPublish, Flash publishes and records live data, appending the

recorded data to a file named

whatToPublish.flv, stored on the server in a subdirectory

within the directory containing the server application. If no file named whatToPublish.flv is

found, it is created.

• If you omit this parameter or pass "live", Flash publishes live data without recording it. If

whatToPublish.flv exists, it will be deleted.

Returns

Nothing.

Description

Method; sends streaming audio, video and text messages from the client to the Flash

Communication Server, optionally recording the stream during transmission. This method is

available only to the publisher of the specified stream.

You don’t use this command when you want to let a subscriber play a stream that has already been

published and recorded. For example, assume you have recorded a stream named “allAboutMe.”

To enable someone to play it back, you need only open a stream for the subscriber to use:

publishStream = new NetStream(someConnection);

subscribeStream = new NetStream(someConnection);

subscribeStream.play("allAboutMe");

When you record a stream, Flash creates an FLV file and stores it in a subdirectory of the

FlashCom application directory on the server. Each stream is stored in a directory whose name is

the same as the

instanceName passed to NetConnection.connect. Flash creates these directories

automatically; you don’t have to create one for each instance name. For example:

// Connect to a specific instance of an app that is stored in

// a directory named "lectureSeries" in your applications directory

nc = new NetConnection();

nc.connect("rtmp://server.domain.com/lectureSeries/Monday")

ns = new NetStream(nc);

ns.publish("lecture", "record")

// a file named "lecture.flv" is stored in a subdirectory named

// "...\yourAppsFolder\lectureSeries\streams\Monday"

// Connect to a different instance of the same app

// but issue an identical publish command

nc = new NetConnection();

nc.connect("rtmp://server.domain.com/lectureSeries/Tuesday")

ns = new NetStream(nc);

ns.publish("lecture", "record")

// a file named "lecture.flv" is stored in a subdirectory named

// "...\yourAppsFolder\lectureSeries\streams\Tuesday"

If you don’t pass a value for instanceName, whatToPublish.flv is stored in a subdirectory named

“...\yourAppsFolder\appName\streams\_definst_” (for “default instance”). For more information

on using instance names, see

NetConnection.connect. For information on playing back FLV

files, see

NetStream.play.

This method can invoke

NetStream.onStatus with a number of different information objects.

For example, if someone is already publishing on a stream with the specified name,

NetStream.onStatus is called with a code property of "NetStream.Publish.BadName". For

more information, see

NetStream.onStatus.
