/**
 * 

4cc = "{@value #TYPE}"

* This object contains an Object Descriptor or an Initial Object Descriptor. * There are a number of possible file types based on usage, depending on the descriptor: *
    *
  • Presentation, contains IOD which contains a BIFS stream (MP4 file); *
  • Sub-part of a presentation, contains an IOD without a BIFS stream (MP4 file);
  • *
  • Sub-part of a presentation, contains an OD (MP4 file);
  • *
  • Free-form file, referenced by MP4 data references (free-format);
  • *
  • Sub-part of a presentation, referenced by an ES URL.
  • *
*

NOTE:

*

The first three are MP4 files, a file referenced by a data reference is not necessarily an MP4 file, as it is * free-format. Files referenced by ES URLs, by data references, or intended as input to an editing process, need not have * an Object Descriptor Box.

*

An OD URL may point to an MP4 file. Implicitly, the target of such a URL is the OD/IOD located in the 'iods' * atom in that file.

*

If an MP4 file contains several object descriptors, only the OD/IOD in the 'iods' atom can be addressed using * an OD URL from a remote MPEG-4 presentation.
