Interface MonitorControl

All Superinterfaces:

Control

public interface MonitorControl

extends Control

Some capture devices or encoders may have a monitor to view/listen to the capture or encoding progress. The MonitorControl allows you to enable/disable monitoring and in the case of a video monitor, also control the preview rate. Setting a lower preview rate will result in lesser resource consumption.

Since:

JMF 2.0
