Classpublic dynamic class NetStreamPlayOptions
InheritanceNetStreamPlayOptions Inheritance EventDispatcher Inheritance Object

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5, Flash Lite 4

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, Flash Lite 4

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.

Related API Elements

offset

property 
public var offset:Number

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10.1, AIR 2, Flash Lite 4

The absoulte stream time at which the server switches between streams of different bitrates for Flash Media Server dynamic streaming. The offset property is used when a NetStream.play2() call is made with the NetStreamPlayTransitions.SWITCH transition mode. There are two switching modes: fast switch and standard switch. The default value of offset is -1 which is fast switch mode. Write ActionScript logic to decide when to use fast switch and when to use standard switch.

Fast switch

In fast switch mode, Flash Media Server switches to the new stream without waiting to play the data in the buffer. Any data buffered from the old stream past the offset is flushed. Fast switching is faster than standard switching because the buffered data from the old stream doesn't have to play out.

The default value of offset is -1, which is fast switch mode. When offset is -1, the switch occurs at the first available keyframe after netstream.time + 3, which is about 3 seconds later than the playback point. You can also set the offset property to any value greater than netstream.time. For example, to fast switch 5 seconds after the playback point, set the offset property to netstream.time + 5. If the value of offset is less than netstream.time, a NetStream.Play.Failed status event is sent.

Note: The offset property is absolute stream time, it is not an offset from the playback point. For example, to switch 5 seconds from the playback point, set the offset property to netstream.time + 5, not to 5.

Standard switch

To use standard switch instead of fast switch, set offset to a value greater than netstream.time + netstream.bufferLength.

Use standard switch when the client has a high bitrate in the buffer and wants to switch to a lower bandwidth due to bandwidth dropping (and not due to CPU issues or dropped frames). The client may want to play out the higher bitrate for as long as possible and switch to the lower bitrate at the end of the buffer (as in standard switching).

For more information, see "Fast switching between streams" in the Adobe Flash Media Server Developer's Guide.

Related API Elements

oldStreamName

property 
public var oldStreamName:String

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5, Flash Lite 4

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.

Related API Elements

start

property 
public var start:Number

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5, Flash Lite 4

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.

Related API Elements

streamName

property 
public var streamName:String

Language Version: ActionScript 3.0
Runtime Versions: Flash Player 10, AIR 1.5, Flash Lite 4

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
