flash.net.NetStreamPlayOptions - Adobe® Flex® 4 Language Reference (Flex 4)

Package	flash.net
Class	public dynamic class NetStreamPlayOptions
Inheritance	NetStreamPlayOptions EventDispatcher Object

Language Version:

ActionScript 3.0

Runtime Versions:

Flash Player 10, AIR 1.5

The NetStreamPlayOptions class specifies the various options that can be passed to the NetStream.play2() method. You pass a NetStreamPlayOptions object to play2(), and the properties of the class specify the various options. The primary use case for this class is to implement transitions between streams dynamically, either to switch to streams of different bit rates and sizes or to swap to different content in a playlist.

Property Detail

len

property

public var len:Number

Language Version:

ActionScript 3.0

Runtime Versions:

Flash Player 10, AIR 1.5

The duration of playback, in seconds, for the stream specified in streamName. The default value is -1, which means that Flash Player plays a live stream until it is no longer available or plays a recorded stream until it ends. If you pass 0 for len, Flash Player plays the single frame that is start seconds from the beginning of a recorded stream (assuming that start is equal to or greater than 0).

If you pass a positive number for len, Flash Player plays a live stream for len seconds after it becomes available, or plays a recorded stream for len seconds. (If a stream ends before len seconds, playback ends when the stream ends.)

If you pass a negative number other than -1 for len, Flash Player interprets the value as if it were -1.

oldStreamName

property

public var oldStreamName:String

Language Version:

ActionScript 3.0

Runtime Versions:

Flash Player 10, AIR 1.5

The name of the old stream or the stream to transition from. When NetStream.play2() is used to simply play a stream (not perform a transition), the value of this property should be either null or undefined. Otherwise, specify the stream to transition from.

start

property

public var start:Number

Language Version:

ActionScript 3.0

Runtime Versions:

Flash Player 10, AIR 1.5

The start time, in seconds, for streamName. Valid values are -2, -1, and 0.

The default value for start is -2, which means that Flash Player first tries to play the live stream specified in streamName. If a live stream of that name is not found, Flash Player plays the recorded stream specified in streamName. If neither a live nor a recorded stream is found, Flash Player opens a live stream named streamName, even though no one is publishing on it. When someone does begin publishing on that stream, Flash Player begins playing it.

If you pass -1 for start, Flash Player plays only the live stream specified in streamName. If no live stream is found, Flash Player waits for it indefinitely if len is set to -1; if len is set to a different value, Flash Player waits for len seconds before it begins playing the next item in the playlist.

If you pass 0 or a positive number for start, Flash Player plays only a recorded stream named streamName, beginning start seconds from the beginning of the stream. If no recorded stream is found, Flash Player begins playing the next item in the playlist immediately.

If you pass a negative number other than -1 or -2 for start, Flash Player interprets the value as if it were -2.

len

streamName

property

public var streamName:String

Language Version:

ActionScript 3.0

Runtime Versions:

Flash Player 10, AIR 1.5

The name of the new stream to transition to or to play. When oldStreamName is null or undefined, calling NetStream.play2() simply starts playback of streamName. If oldStreamName is specified, calling NetStream.play2() transitions oldStreamName to streamName using the transition mode specified in the transition property.

transition

property

public var transition:String

Language Version:

ActionScript 3.0

Runtime Versions:

Flash Player 10, AIR 1.5

The mode in which streamName is played or transitioned to. Possible values are constants from the NetStreamPlayTransitions class. Depending on whether Netstream.play2() is called to play or transition a stream, the transition mode results in different behaviors. For more information on the transition modes, see the NetStreamPlayTransitions class.

Constructor Detail
