Class QuickTimeMeta.MediaSample

java.lang.Object

org.monte.media.quicktime.QuickTimeMeta.MediaSample

Enclosing class:

QuickTimeMeta

protected static class QuickTimeMeta.MediaSample
extends Object

QuickTime stores media data in media samples. A media sample is a single element in a sequence of time-ordered data. Information about samples is stored in the mdat atom.

Please note that MediaSample objects are created on demand. This helps to save memory, because a highly multiplexed audio track may consist of many samples per second. As a consequence multiple instances of MediaSample objects may represent the same data sample in the movie.
