SERVER-SIDE ACTIONSCRIPT LANGUAGE REFERENCE FOR ADOBE MEDIA SERVER 5.0.1

Server-Side ActionScript Language Reference

Last updated 7/2/2013

Controls the data source of a stream with an optional start time, duration, and reset flag to flush any previously playing

stream. Call

play() to do the following:

• Chain streams between servers.

• Create a hub to switch between live streams and recorded streams.

• Combine streams into a recorded stream.

You can combine multiple streams to create a playlist for clients. The Stream.play() method behaves differently

from the

NetStream.play() method on the client side. A server-side call to Stream.play() is similar to a client-side

call to

NetStream.publish(); it controls the source of data coming into a stream. When you call Stream.play() on

the server, the server becomes the publisher. Because the server has higher priority than the client, the client is forced

to unpublish from the stream if the server calls a

play() method on the same stream.

If any recorded streams are included in a server playlist, you cannot play the server playlist stream as a live stream.

Note: A stream that plays from a remote server by means of the NetConnection object is considered a live stream.

You do not need to wait for "NetStatus.Connection.Success" when connecting to another Adobe Media Server

from Server-Side Actionscript. The server waits for the connection to complete before it attempts to use the connection

for

Stream.play(). However, you may want to monitor the NetStatusEvent so that you can handle a failed

connection.

To delete a Stream object, use the delete operator to mark the stream for deletion. The script engine deletes the object

during its garbage collection routine.

// Initialize the Stream object.

s = stream.get("foo");

// Play the stream.

s.play("name", p1, ... pN);

// Stop the stream.

s.play(false);

// Mark the Stream object for deletion during server garbage routine.

delete s;

Flash Communication Server 1

Parameters

streamName A string indicating the name of the stream. Use the following syntax:

startTime A number indicating the playback start time, in seconds. If no value is specified, the value is -2. If

startTime is -2, the server tries to play a live stream with the name specified in streamName. If no live stream is

available, the server tries to play a recorded stream with the name specified in

streamName. If no recorded stream is

File format Syntax Example

FLV Specify the stream name as a string, without a filename

extension.

s.play("fileName")

MP3 Specify the stream name as a string, with prefix mp3: or id3:,

respectively, and without a filename extension.

s.play("mp3:fileName")

s.play("id3:fileName")

MPEG-4-based files (such as

F4V, MP4)

Specify the stream name as a string with the prefix mp4:. Use

a file extension if the file on the server has a file extension. The

prefix indicates to the server that the file is in the MPEG-4 Part

12 container format.

s.play("mp4:fileName")

s.play("mp4:fileName.mp4")

s.play("mp4:fileName.f4v")
