Several clients connecting to multiple applications (sudoku and scrabble) and application instances (room 2, room 1, and room 2) running on
Flash Media Server
Parts of a media application
The client application is written in ActionScript™ and compiles to a SWF file. The server application is code written
in Server-Side ActionScript (which is similar to ActionScript 1.0, but runs on the server, rather than on the client).
A media application usually has recorded or live audio and video that it streams from server to client, client to server,
or server to server.
A typical Flash Media Server application has these parts:
The client displays a user interface, such as controls to start, stop, or pause a video. The user
Client user interface
interface can run in Flash Player, AIR, or Flash Lite 3 and can be developed with Adobe Flash or Adobe Flex.
The client contains ActionScript code that handles user interaction and connects to the
Client-side ActionScript
server. Flash Media Server 3 supports ActionScript 3.0. Client applications developed in ActionScript 2.0 or Action-
Script 1.0 for an earlier version of Flash Media Server are compatible with Flash Media Server 3.
Many media applications stream recorded audio or video from the server to clients, or from a client
Video or audio
to the server and then to other clients. Prerecorded files may be in Flash Video (FLV), MP3, or MP4 format. Video
files recorded by the server are always in FLV format, with the suffix .flv. See
A client can stream live video or audio to the server using the
Camera or microphone
or your own custom Flash application that supports live streaming. The client captures audio and video using its own
microphone and camera.
Many applications include Server-Side ActionScript code packaged in a file with the suffix
Server-Side ActionScript
.asc, formally called an ActionScript Communication File. The file is named either main.asc, or myApplication.asc (see
Writing server-side code). The server-side code handles the work the server does, such as streaming audio and video
and defining what happens when users connect and disconnect. See the Server-Side ActionScript Language Reference.
Stream formats
Flash Media Server supports playback of a variety of stream formats, including Flash Video (FLV), MPEG-3 (MP3),
and MPEG-4 (MP4). For more information, see Adobe Flash Media Server Technical Overview.
