| /** |
| * 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: |
| * <ul> |
| * <li>Presentation, contains IOD which contains a BIFS stream (MP4 file); |
| * <li>Sub-part of a presentation, contains an IOD without a BIFS stream (MP4 file);</li> |
| * <li>Sub-part of a presentation, contains an OD (MP4 file);</li> |
| * <li>Free-form file, referenced by MP4 data references (free-format);</li> |
| * <li>Sub-part of a presentation, referenced by an ES URL.</li> |
| * </ul> |
| * NOTE: <br/> |
| * 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. <br/> |
| * 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.</br/> |
| * 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. |
