Class FrameProcessingControlImpl

java.lang.Object

org.jitsi.impl.neomedia.control.FrameProcessingControlImpl

All Implemented Interfaces:

javax.media.Control, javax.media.control.FrameProcessingControl

public class FrameProcessingControlImpl
extends Object
implements javax.media.control.FrameProcessingControl

Provides a base implementation of FrameProcessingControl which keeps track of the minimalProcessing property, switches its value to true when it's notified that its owner is at least one frame behind and doesn't implement the controlComponent and framesDropped properties.

public FrameProcessingControlImpl()

Method Detail

getControlComponent

public Component getControlComponent()

Gets the UI Component associated with this Control object.

Specified by:

getControlComponent in interface javax.media.Control

Returns:

the UI Component associated with this Control object

getFramesDropped

public int getFramesDropped()

Gets the number of output frames that were dropped during processing since the last call to this method.

Specified by:

getFramesDropped in interface javax.media.control.FrameProcessingControl

Returns:

the number of output frame that were dropped during processing since the last call to this method

isMinimalProcessing

public boolean isMinimalProcessing()

Determines whether the owner of this FrameProcessingControl is to perform only the minimum operations necessary to keep it working normally but without producing output.

Returns:

true if the owner of this FrameProcessingControl is to perform only the minimum operations necessary to keep it working normally but without producing output; otherwise, false

setFramesBehind

public void setFramesBehind(float framesBehind)

Sets the number of frames the owner of this FrameProcessingControl is lagging behind. It is a hint to do minimal processing for the next framesBehind frames in order to catch up.

Specified by:

setFramesBehind in interface javax.media.control.FrameProcessingControl

Parameters:

framesBehind - the number of frames the owner of this FrameProcessingControl is lagging behind

setMinimalProcessing

public boolean setMinimalProcessing(boolean minimalProcessing)

Sets the indicator which determines whether the owner of this FrameProcessingControl is to perform only the minimal operations necessary to keep it working normally but without producing output.

Specified by:

setMinimalProcessing in interface javax.media.control.FrameProcessingControl

Parameters:

minimalProcessing - true if minimal processing mode is to be turned on or false if minimal processing mode is to be turned off

Returns:

the actual minimal processing mode in effect after the set attempt
