public class flexTPSRecorder
extends Object

flexTPSRecorder is a class (and application) to record JPEG snapshots of a set of streams from a flexTPS server. This class is mainly for recording time-lapse video so the recording rate (or period) should be slow. On the order of seconds, minutes, or hours.

The snapshots will be saved to disk (in the optional specified directory) using the filename format: <feed>-<stream>_<timestamp>.jpg.
