This class represents a file in ISO base media file format as described in ISO/IEC 14496 Part 12 standard.
The ISO Base Media File Format is designed to contain timed media information for a presentation in a flexible, extensible format that facilitates interchange, management, editing, and presentation of the media. This presentation may be local to the system containing the presentation, or may be via a network or other stream delivery mechanism.
The file structure is object-oriented; a file can be decomposed into constituent objects very simply, and the structure of the objects inferred directly from their type. The file format is designed to be independent of any particular network protocol while enabling efficient support for them in general.
The ISO Base Media File Format is a base format for media file formats.
An overall view of the normal encapsulation structure is provided in the following table.
The table shows those boxes that may occur at the top-level in the left-most column; indentation is used to show possible containment. Thus, for example, a Track Header Box is found in a Track Box, which is found in a Movie Box. Not all boxes need be used in all files; the mandatory boxes are marked with bold typeface. See the description of the individual boxes for a discussion of what must be assumed if the optional boxes are not present.
User data objects shall be placed only in Movie or Track Boxes, and objects using an extended type may be placed in a wide variety of containers, not just the top level.
There are two non-standard extensions to the ISO 14496 standard that add the ability to include file meta information. Both the boxes reside under moov.udta.meta.
