WebcamSubscriber is the foundation class for receiving and displaying webcam video in a meeting room. By default, WebcamSubscriber simply subscribes to StreamManager notifications and plays all webcam video present in the room. It can also accept an array of userIDs which restricts the list of publishers that can publish to this subscriber. Note that this is a lower level component aimed at making the display of one or more webcam videos simple. For a higher-level control with UI controls, see com.adobe.rtc.pods.WebCamera.

Like all stream components, WebcamSubscriber has an API for setting and getting a groupName. This property can be used to create multiple and separate video groups with different access/publish models, thereby allowing for multiple private conversations. For a subscriber to listen to a particular video stream from a publisher, both should have the same assigned groupName. If no groupName is assigned, the publisher defaults to publishing to the public group.

Property detail
accessModelproperty
accessModel:int  [read-write]

The role value required for accessing video streams for this component's group.

Implementation
    public function get accessModel():int
    public function set accessModel(value:int):void
connectSessionproperty 
connectSession:IConnectSession  [read-write]

The IConnectSession with which this component is associated, the default being the first IConnectSession created in the application. Note that this may only be set once before subscribe() is called; re-sessioning of components is not supported.

Implementation
    public function get connectSession():IConnectSession
    public function set connectSession(value:IConnectSession):void
deblockingproperty 
deblocking:int  [read-write]

Indicates the type of filter applied to decoded video as part of post-processing. The default value is 0, which lets the video compressor apply a deblocking filter as needed. visit http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/media/Video.html#deblocking for more info. We currently allow only one deblocking value for all video streams on subscriber.

Implementation
    public function get deblocking():int
    public function set deblocking(value:int):void
displayUserBarsproperty 
public var displayUserBars:Boolean = true

Determines whether the user bar above video streams is displayed. By default, the user bar is displayed (true).

groupNameproperty 
groupName:String  [read-write]

Components (pods) are assigned to a group via groupName; if not specified, the component is assigned to the default, public group (the room at large). Groups are like separate conversations within the room, but each conversation could employ one or more pods; for example, one "conversation" may use a web camera, chat, and whiteboard pod, with each pod using different access and publish models. Users are members of and can only see components within the group they are assigned. Room hosts can see all the groups and all the members in those groups.

Implementation
    public function get groupName():String
    public function set groupName(value:String):void
heightproperty 
height:Number  [read-write]Implementation
    public function get height():Number
    public function set height(value:Number):void

The role required for this component to publish to the group specified by groupName.

Implementation
    public function get publishModel():int
    public function set publishModel(value:int):void
sharedIDproperty 
sharedID:String  [read-write]

Defines the logical location of the component on the service; typically this assigns the sharedID of the collectionNode used by the component. sharedIDs should be unique within a room if they're expressing two unique locations. Note that this can only be assigned once before subscribe() is called. For components with an id property, sharedID defaults to that value.

Implementation
    public function get sharedID():String
    public function set sharedID(value:String):void
streamCountproperty 
public var streamCount:int = 0

[read-only] Returns the number of streams currently displayed by the subscriber.
