SERVER-SIDE ACTIONSCRIPT LANGUAGE REFERENCE FOR ADOBE MEDIA SERVER 5.0.1

Server-Side ActionScript Language Reference

Last updated 7/2/2013

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 parameter

is optional.

length A number indicating 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 parameter is optional.

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.

You can also specify a number value of 2 or 3 for the reset parameter, which is useful when playing recorded stream

files that contain message data. These values are analogous to

false (0) and true (1), respectively: a value of 2

maintains a playlist, and a value of 3 resets the playlist. However, the difference is that specifying either 2 or 3 for

reset

returns all messages in the specified recorded stream at once, rather than at the intervals at which the messages were

originally recorded (the default behavior).

remoteConnection A NetConnection object that is used to connect to a remote server. If this parameter is provided,

the requested stream plays from the remote server. This is an optional parameter.

virtualKey A string indicating a key value. Starting with Adobe Media Server 2, stream names are not always unique;

you can create multiple streams with the same name, place them in different physical directories, and use the

VirtualDirectory section and VirtualKeys section of the Vhost.xml file to direct clients to the appropriate stream.

Because the

Stream.length() method is not associated with a client, but connects to a stream on the server, you may

need to specify a virtual key to identify the correct stream. For more information about keys, see

Client.virtualKey.

This is an optional parameter.

Returns

A boolean value: true if the call is accepted by the server; otherwise, false. If the server fails to find the stream, or if

an error occurs, the

Stream.play() method can fail. To get information about the Stream.play() method, define a

Stream.onStatus() handler.

If the streamName parameter is false, the stream stops playing. A boolean value of true is returned if the stop

succeeds; otherwise,

false.

Example

The following example shows how streams can be chained between servers:

1 2 ... 159 160 161 162 163 164 165 166 167 168 169 170 171 172
