The DynamicStreamingVideoSource class represents a streaming video source and can be used for streaming pre-recorded video or live streaming video. You use this class to define a video stream for the VideoPlayer and VideoDisplay controls.

This class supports a single stream or multiple streams associated with different bitrates. The VideoPlayer and VideoDisplay classes can take a DynamicStreamingVideoSource instance as its source property.

Property Detail

host

property

host:Object

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

The URI of the location of the video server. While this property is of type Object, pass the URI as a String.

Use the streamName property of the DynamicStreamingVideoItem class to specify stream name on the server.

Implementation
public function get host():Object
public function set host(value:Object):void

initialIndex

property

initialIndex:int

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

The preferred starting index. This corresponds to the stream item that should be attempted first.

Implementation
public function get initialIndex():int
public function set initialIndex(value:int):void

streamItems

property

streamItems:Vector.<DynamicStreamingVideoItem>

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

The metadata info object with properties describing the FLB file.

Implementation
public function get streamItems():Vector.<DynamicStreamingVideoItem>
public function set streamItems(value:Vector.<DynamicStreamingVideoItem>):void

streamType

property

streamType:String

Language Version:

ActionScript 3.0

Product Version:

Flex 4

Runtime Versions:

Flash Player 10, AIR 1.5

The type of stream we are trying to connect to: any, live, or recorded.

If the streamType is any, then we will attempt to connect to a live stream first. If no live stream is found, we will attempt to connect to a recorded stream. If no recorded stream is found, then a live stream will be created.

The default value is any.

Implementation
public function get streamType():String
public function set streamType(value:String):void

DynamicStreamingVideoSource

()

Constructor

public function DynamicStreamingVideoSource()
