All Implemented Interfaces:

KeyListener, EventListener

public class VideoCaptureFramesExample
extends KeyAdapter

Example showing how the built-in OpenIMAJ fps counter works and how to dipsplay real-time fps. Since VideoDisplay.getDisplayFPS() reports FPS speed with which display is updated, it is not necessairly the speed at which FPS is rendered out to the display. This program shows this discrepancy. Notice that while "capture" FPS reports at the consistent range, depending on frame delay set, the actual render FPS may be quite different. This demo implementation uses simple thread sleep to simulate expensive rendering operation.
