Class MediaTime

java.lang.Object

org.mbari.vcr4j.time.MediaTime

public class MediaTime
extends Object

Time modeled after Apple's CoreMedia CMTime. A MediaTime is represented as a rational number, with a numerator (an long value), and a denominator (an int timescale). Conceptually, the timescale specifies the fraction of a second each unit in the numerator occupies. Thus if the timescale is 4, each unit represents a quarter of a second; if the timescale is 10, each unit represents a tenth of a second, and so on.
