Server-Side Communication ActionScript 69

Description

Event handler; invoked every time the status of a Stream object changes. For example, if you play

a file in a stream,

Stream.onStatus is invoked. Use Stream.onStatus to check when play starts

and ends, when recording starts, and so on.

Example

This example defines a function that executes whenever the Stream.onStatus event is invoked:

s = Stream.get("foo");

s.onStatus = function(info){

// insert code here

};

Stream.play

Availability

Flash Communication Server MX.

Usage

Stream.play(streamName, [startTime, length, reset, remoteConnection])

Parameters

streamName The name of any published live stream, recorded stream (FLV file), or MP3 file.

To play back FLV files, the default Flash file format for recorded streams, specify the name of the

stream (for example,

"myVideo"). To play back MP3 files that you’ve stored on the server, or the

ID3 tags of MP3 files, you must precede the stream name with

mp3: or id3: (for example,

"mp3:bolero" or "id3:bolero"). For more information on playing MP3 files, see Developing

Communication Applications.

startTime The start time of the stream playback, in seconds. If no value is specified, it is set to

-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 found, the server creates a live stream with the

name specified in

streamName and waits for someone to publish to that stream. If startTime is

-1, the server attempts to play a live stream with the name specified in

streamName and waits for

a publisher if no specified live stream is available. If

startTime is greater than or equal to 0, the

server plays the recorded stream with the name specified in

streamName, starting from the time

given. If no recorded stream is found, the

play method is ignored. If a negative value other than

-1 is specified, the server interprets it as -2. This is an optional parameter.

length The length of play, in seconds. For a live stream, a value of -1 plays the stream as long as

the stream exists. Any positive value plays the stream for the corresponding number of seconds.

For a recorded stream, a value of -1 plays the entire file, and a value of 0 returns the first video

frame. Any positive number plays the stream for the corresponding number of seconds. By

default, the value is -1. This is an optional parameter.

reset A Boolean value, or number, that flushes the playing stream. If reset is false (0), the

server maintains a playlist, and each call to

Stream.play is appended to the end of the playlist so

that the next play does not start until the previous play finishes. You can use this technique to

create a dynamic playlist. If

reset is true (1), any playing stream stops, and the playlist is reset.

By default, the value is

true.
