Class MediaDataBox

java.lang.Object
  com.coremedia.iso.boxes.mdat.MediaDataBox

All Implemented Interfaces:

Box

public final class MediaDataBox
extends Object
implements Box

This box contains the media data. In video tracks, this box would contain video frames. A presentation may contain zero or more Media Data Boxes. The actual media data follows the type field; its structure is described by the metadata (see SampleTableBox).
In large presentations, it may be desirable to have more data in this box than a 32-bit size would permit. In this case, the large variant of the size field is used.
There may be any number of these boxes in the file (including zero, if all the media data is in other files). The metadata refers to media data by its absolute offset within the file (see StaticChunkOffsetBox); so Media Data Box headers and free space may easily be skipped, and files without any box structure may also be referenced and used.
