StreamingURLResource is a URLResource which is capable of being streamed. It exposes some additional properties which are specific to streaming media.

Note that it is possible for live and recorded streams to have identical URLs. In such a case, the streamType property should be used to disambiguate live and recorded streams.

Descrizione delle proprietà

clipEndTime

proprietà

clipEndTime:Number

Optional end time of the streaming resource. When specified, the stream will be presented as a subclip, with playback ending at the specified end time. Note that clipEndTime is not currently supported for progressive videos. The default is NaN, which is to play to the end.

Implementazione
public function get clipEndTime():Number
public function set clipEndTime(value:Number):void

clipStartTime

proprietà

clipStartTime:Number

Optional start time of the streaming resource. When specified, the stream will be presented as a subclip, with playback beginning at the specified start time. Note that clipStartTime is not currently supported for progressive videos. The default is NaN, which is to start at the beginning.

Implementazione
public function get clipStartTime():Number
public function set clipStartTime(value:Number):void

connectionArguments

proprietà

connectionArguments:Vector.<Object>

Optional set of arguments that will be supplied when making a connection to the source of the stream.

Implementazione
public function get connectionArguments():Vector.<Object>
public function set connectionArguments(value:Vector.<Object>):void

drmContentData

proprietà

drmContentData:ByteArray

Content metadata for DRM-encrypted content.

Implementazione
public function get drmContentData():ByteArray
public function set drmContentData(value:ByteArray):void

String value	Description
`StreamType.LIVE_OR_RECORDED`	The StreamingURLResource represents either a live or a recorded stream.
`StreamType.LIVE`	The StreamingURLResource represents a live stream.
`StreamType.RECORDED`	The StreamingURLResource represents a recorded stream.
`StreamType.DVR`	The StreamingURLResource represents a DVR stream.

urlIncludesFMSApplicationInstance

proprietà

urlIncludesFMSApplicationInstance:Boolean

Indicates, for RTMP streaming URLs, whether the URL includes the FMS application instance or not. If true, then the second part of the URL path is considered the instance name, such as rtmp://host/app/foo/bar/stream. In this case the instance name would be 'foo' and the stream would be 'bar/stream'. If false, then the second part of the URL path is considered to be the stream name, such as rtmp://host/app/foo/bar/stream. In this case there is no instance name and the stream would be 'foo/bar/stream'. The default is false.

Implementazione
public function get urlIncludesFMSApplicationInstance():Boolean
public function set urlIncludesFMSApplicationInstance(value:Boolean):void

Constructor.

Parametri

	`url:String` — The URL of the resource. For details about how to format this URL for flv, mp4, and other file formats, see the Adobe® Flash® Media Server documentation link below.

	`streamType:String` (default = `null`) — The type of the stream. If null, defaults to StreamType.RECORDED.

	`clipStartTime:Number` (default = `NaN`) — Optional start time of the streaming resource. When specified, the stream will be presented as a subclip, with playback beginning at the specified start time.

	`clipEndTime:Number` (default = `NaN`) — Optional end time of the streaming resource. When specified, the stream will be presented as a subclip, with playback ending at the specified end time.

	`connectionArguments:Vector.<Object>` (default = `null`) — Optional set of arguments that will be supplied to NetConnection.connect when establishing a connection to the source of the stream.

	`urlIncludesFMSApplicationInstance:Boolean` (default = `false`) — Indicates, for RTMP streaming URLs, whether the URL includes the FMS application instance or not. If true, then the second part of the URL path is considered the instance name, such as `rtmp://host/app/foo/bar/stream`. In this case the instance name would be 'foo' and the stream would be 'bar/stream'. If false, then the second part of the URL path is considered to be the stream name, such as `rtmp://host/app/foo/bar/stream`. In this case there is no instance name and the stream would be 'foo/bar/stream'. The default is false.

	`drmContentData:ByteArray` (default = `null`) — Content metadata for DRM-encrypted content.
