Method Summary

All Methods Instance Methods Abstract Methods Deprecated Methods
Modifier and Type	Method	Description
`void`	`addVideoListener(VideoListener listener)`	Adds a specific `VideoListener` to this `VideoMediaStream` in order to receive notifications when visual/video `Component`s are being added and removed.
`KeyFrameControl`	`getKeyFrameControl()`	Gets the `KeyFrameControl` of this `VideoMediaStream`.
`Component`	`getLocalVisualComponent()`	Gets the visual `Component`, if any, depicting the video streamed from the local peer to the remote peer.
`BandwidthEstimator`	`getOrCreateBandwidthEstimator()`	Creates an instance of `BandwidthEstimator` for this `MediaStream` if one doesn't already exist.
`QualityControl`	`getQualityControl()`	Gets the `QualityControl` of this `VideoMediaStream`.
`Component`	`getVisualComponent()`	Deprecated. Since multiple videos may be received from the remote peer and rendered, it is not clear which one of them is to be singled out as the return value.
`Component`	`getVisualComponent(long ssrc)`	Gets the visual `Component` rendering the `ReceiveStream` with a specific SSRC.
`List<Component>`	`getVisualComponents()`	Gets a list of the visual `Component`s where video from the remote peer is being rendered.
`void`	`movePartialDesktopStreaming(int x, int y)`	Move origin of a partial desktop streaming `MediaDevice`.
`void`	`removeVideoListener(VideoListener listener)`	Removes a specific `VideoListener` from this `VideoMediaStream` in order to have to no longer receive notifications when visual/video `Component`s are being added and removed.
`void`	`updateQualityControl(Map<String,String> advancedParams)`	Updates the `QualityControl` of this `VideoMediaStream`.

- Field Detail
  - REQUEST_RETRANSMISSIONS_PNAME
```
static final String REQUEST_RETRANSMISSIONS_PNAME
```
    The name of the property used to control whether VideoMediaStream should request retransmissions for lost RTP packets using RTCP NACK.
- Method Detail
  - addVideoListener
```
void addVideoListener(VideoListener listener)
```
    Adds a specific VideoListener to this VideoMediaStream in order to receive notifications when visual/video Components are being added and removed.
    Adding a listener which has already been added does nothing i.e. it is not added more than once and thus does not receive one and the same VideoEvent multiple times
    
    Parameters:
    
    listener - the VideoListener to be notified when visual/video Components are being added or removed in this VideoMediaStream
  - getKeyFrameControl
```
KeyFrameControl getKeyFrameControl()
```
    Gets the KeyFrameControl of this VideoMediaStream.
    
    Returns:
    
    the KeyFrameControl of this VideoMediaStream
  - getLocalVisualComponent
```
Component getLocalVisualComponent()
```
    Gets the visual Component, if any, depicting the video streamed from the local peer to the remote peer.
    
    Returns:
    
    the visual Component depicting the local video if local video is actually being streamed from the local peer to the remote peer; otherwise, null
  - getQualityControl
```
QualityControl getQualityControl()
```
    Gets the QualityControl of this VideoMediaStream.
    
    Returns:
    
    the QualityControl of this VideoMediaStream
  - getVisualComponent
```
@Deprecated
Component getVisualComponent()
```
    Deprecated.
    Since multiple videos may be received from the remote peer and rendered, it is not clear which one of them is to be singled out as the return value. Thus getVisualComponent(long) and getVisualComponents() are to be used instead.
    
    Gets the visual Component where video from the remote peer is being rendered or null if no video is currently being rendered.
    
    Returns:
    
    the visual Component where video from the remote peer is being rendered or null if no video is currently being rendered
  - getVisualComponent
```
Component getVisualComponent(long ssrc)
```
    Gets the visual Component rendering the ReceiveStream with a specific SSRC.
    
    Parameters:
    
    ssrc - the SSRC of the ReceiveStream to get the associated rendering visual Component of
    
    Returns:
    
    the visual Component rendering the ReceiveStream with the specified ssrc if any; otherwise, null
  - getVisualComponents
```
List<Component> getVisualComponents()
```
    Gets a list of the visual Components where video from the remote peer is being rendered.
    
    Returns:
    
    a list of the visual Components where video from the remote peer is being rendered
  - movePartialDesktopStreaming
```
void movePartialDesktopStreaming(int x,
                                 int y)
```
    Move origin of a partial desktop streaming MediaDevice.
    
    Parameters:
    
    x - new x coordinate origin
    
    y - new y coordinate origin
  - removeVideoListener
```
void removeVideoListener(VideoListener listener)
```
    Removes a specific VideoListener from this VideoMediaStream in order to have to no longer receive notifications when visual/video Components are being added and removed.
    
    Parameters:
    
    listener - the VideoListener to no longer be notified when visual/video Components are being added or removed in this VideoMediaStream
  - updateQualityControl
```
void updateQualityControl(Map<String,String> advancedParams)
```
    Updates the QualityControl of this VideoMediaStream.
    
    Parameters:
    
    advancedParams - parameters of advanced attributes that may affect quality control
  - getOrCreateBandwidthEstimator
```
BandwidthEstimator getOrCreateBandwidthEstimator()
```
    Creates an instance of BandwidthEstimator for this MediaStream if one doesn't already exist. Returns the instance.
