public class TimeFrameI extends Object
Integer time frame in milliseconds, maybe specialized for texture/video, audio, .. animated content.Type and value range has been chosen to suit embedded CPUs and characteristics of audio / video streaming and animations. Milliseconds of type integer with a maximum value of
Integer.MAX_VALUE
will allow tracking time up 2,147,483.647 seconds or 24 days 20 hours 31 minutes and 23 seconds.Milliseconds granularity is also more than enough to deal with A-V synchronization, where the threshold usually lies within 22ms.
Milliseconds granularity for displaying video frames might seem inaccurate for each single frame, i.e. 60Hz != 16ms, however, accumulated values diminish this error and vertical sync is achieved by build-in V-Sync of the video drivers.
