NetStream.play

Availability

• Flash Player 6.

• Flash Communication Server MX.

Usage

mystream.play(whatToPlay | false [,start [, length [, flushPlaylists]]])

Parameters

whatToPlay An identifying name for live data published by NetStream.publish, a recorded

file name for playback, or

false. If you pass false, the stream stops playing and any additional

parameters you send are ignored.

start An optional numeric parameter that specifies the start time, in seconds. This parameter

can also be used to indicate whether the stream is live or recorded.

• The default value for start is -2, which means that Flash first tries to play the live stream

specified in

whatToPlay. If a live stream of that name is not found, Flash plays the recorded

stream specified in

whatToPlay. If neither a live nor a recorded stream is found, Flash opens a

live stream named

whatToPlay even though no one is publishing on it; when someone does

begin publishing on that stream, Flash begins playing it.

• If you pass -1 for start, Flash plays only the live stream specified in whatToPlay. If no live

stream is found, Flash waits for it indefinitely if

length is set to -1; if length is set to a

different value, Flash waits for

length seconds before it begins playing the next item in

the playlist.

• If you pass 0 or a positive number for start, Flash plays only a recorded stream named

whatToPlay, beginning start seconds from the beginning of the stream. If no recorded

stream is found, Flash begins playing the next item in the playlist immediately.

• If you pass a negative number other than -1 or -2 for start, Flash interprets the value as

if it were -2.

length An optional numeric parameter that specifies the duration of the playback, in seconds.

• The default value for length is -1, which means that Flash plays a live stream until it is no

longer available or plays a recorded stream until it ends.

• If you pass 0 for length, Flash plays the single frame that is start seconds from the beginning

of a recorded stream (assuming

start is equal to or greater than 0).

• If you pass a positive number for length, Flash plays a live stream for length seconds after it

becomes available, or plays a recorded stream for

length seconds. (If a stream ends before

length seconds, playback ends when the stream ends.)

• If you pass a negative number other than -1 for length, Flash interprets the value as

if it were -1.

flushPlaylists An optional Boolean parameter that specifies whether to flush any

previous playlist.

• The default value for flushPlaylists is true, which means that any previous play calls are

cleared and

whatToPlay is played immediately.

• If you pass false for flushPlaylists, whatToPlay is added (queued) in the current playlist;

that is,

whatToPlay plays only after previous streams have completed playing.
