Specifying publishing formats.

You should have Flash MX configured to publish both SWF and

HTML files. To specify formats to be created during publishing, choose File > Publish Settings in

the Flash MX authoring environment.

Writing client-side ActionScript code. Unless otherwise noted, your client-side ActionScript code

should be attached to a layer on the first keyframe of your FLA file, not to individual objects.

Writing server-side ActionScript code. For the samples that use server-side ActionScript code,

your main.asc file should be written in a JavaScript editor, such as Macromedia Dreamweaver

MX. For more information on appropriate JavaScript editors, see “Setting up your development

environment” on page 17. Also, remember that server-side code is case-sensitive.

Initializing your client-side code. Add the following code as the first two lines in each sample as

you re-create it (these lines are in each sample FLA but are not included in the steps for re-

creating the sample):

stop();

#include "netdebug.as"

The first line simply ensures that movies stop running before the sample starts. The second line

enables the use of the NetConnection debugger, which lets you trace and diagnose details about

the streams and shared objects your application is using. For more information on the debugger,

see “Using the NetConnection Debugger” on page 105.

Acknowledging the user’s right to privacy. Before recording or broadcasting anyone’s image or

voice, it’s important to inform that person of your intention and to gain their consent or

agreement. In the samples that illustrate how to record or broadcast audio or video, you’ll see

instructions to add a text box that informs users they are being recorded or broadcasted and

gives them the opportunity to exit the application. For a more robust means of letting users

decide whether they want to be recorded or broadcasted, or not, see “Adding a privacy module”

on page 60.

Monitoring running applications. If you have server administration privileges, you can view details

about an application while you are testing it, such as log messages it is generating, values of shared

objects, and so on. To do so, open the Communication App inspector in Flash MX (Window >

Communication App Inspector), connect to the Flash Communication Server, select the

application instance you want to monitor, and choose View Detail. For more information, see

“Using the Communication App inspector” on page 97.

Sample 1: Recording a Stream

This recording sample records a video stream. When the user clicks the Play button, the recorded

data is streamed back to the Flash movie.

About the sample

The user opens the doc_record.html file. After the user grants access to its video device, the live

output appears in the larger video area called

Live_video. When the user clicks the Record

button, the live camera’s stream is sent for recording on the Flash Communication Server. When

the user clicks the Stop button, the server stops recording. When the user clicks the Play button,

the server sends the recorded stream back to the application, and the recorded stream plays in the

smaller video area.
