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`
