Building a Live Video Switcher with Flash Communication Server MX

Note: This article describes legacy techniques in Adobe Flash for generating web video. To learn about the latest best practices for working with video in newer versions in Flash, please read the Video Learning Guide for Flash and the most recent articles posted in the Video Technology Center.

In this article, you will learn how to build a basic video switcher using Flash MX Professional 2004 and Flash Communication Server MX 1.5. This video switcher enables multiple people to broadcast video and audio to Flash Communication Server, and lets you control what the end user watches. You will learn how to use server-side ActionScript and Flash Communication Server messaging easily to control the source of the stream that your audience watches.

As a bonus, you will even incorporate switching between live and prerecorded video sources—all with nothing more than Flash Player, a camera, and some real personality.

In this article, you will create three Flash movies and one ActionScript communications file:

  • Live video broadcaster (simpleBroadcaster.fla)
  • Live video player (simplePlayer.fla)
  • Video switcher (simpleSwitcher.fla)
  • Server-side ActionScript file (fcsBroadcast.asc)

To help you get started, I created the user interfaces for this article. You can download the basic interface and the completed solution with some bonus material below. The basic interface contains all visual elements with the key ActionScript removed. To follow along with this tutorial, use the files in the fcsBroadcaster_start folder. The completed solution is located within the fcsBroadcaster folder. Both folders should be placed within the flashcom/applications folder on your server.
