/**
|
||||
* 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 {@link ISO14496_Box_TKHD Track Header Box} is found in a
|
||||
* {@link ISO14496_Box_TRAK Track Box}, which is found in a
|
||||
* {@link ISO14496_Box_MOOV 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 {@link ISO14496_Box_MOOV Movie} or
|
||||
* {@link ISO14496_Box_TRAK Track Boxes}, and objects using an extended type may
|
||||
* be placed in a wide variety of containers, not just the top level.

* boxes such as a {@link ISO14496_Box_MOOV Movie Box}, {@link ISO14496_Box_MDAT

* Media Data Box}, or {@link ISO14496_Box_FREE Free Space}). It identifies

|
||||
* of that specification; and also a set of others specifications to which the
|
||||
* file complies.
|
||||
*
|
||||
* The minor version is informative only. It does not appear for
|
||||
* compatible-brands, and must not be used to determine the conformance of a
|
||||
* file to a standard. It may allow more precise identification of the major
|
||||
* specification, for inspection, debugging, or improved decoding.
|
||||
*
|
||||
* The type <i>isom</i> (ISO Base Media file) is defined as identifying files
|
||||
* that conform to the first version of the ISO Base Media File Format. More
|
||||
* specific identifiers can be used to identify precise versions of
|
||||
* specifications providing more detail. This brand is not be used as the major
|
||||
* brand; this base file format should be derived into another specification to
|
||||
* be used. There is therefore no defined normal file extension, or mime type
|
||||
* assigned to this brand, nor definition of the minor version when <i>isom</i>
|
||||
* is the major brand.
|
||||
*
|
||||
* Files would normally be externally identified (e.g. with a file extension or
|
||||
* mime type) that identifies the <i>best use</i> (major brand), or the brand
|
||||
* that the author believes will provide the greatest compatibility.
|
||||
*
|
||||
* The brand <i>iso2</i> shall be used to indicate compatibility with the
|
||||
* amended version of the ISO Base Media File Format; it may be used in addition
|
||||
* to or instead of the <i>isom</i> brand and the same usage rules apply. If
|
||||
* used without the brand <i>isom</i> identifying the first version of the
|
||||
* specification, it indicates that support for some or all of the technology
|
||||
* introduced by the amended version of the ISO Base Media File Format is
|
||||
* required.
|
||||
*
|
||||
* The brand <i>avc1</i> shall be used to indicate that the file is conformant
|
||||
* with the <i>AVC Extensions</i>. If used without other brands, this implies
|
||||
* that support for those extensions is required. The use of <i>avc1</i> as a
|
||||
* major-brand may be permitted by specifications; in that case, that
|
||||
* specification defines the file extension and required behavior.

||||
*

||||
* If a Meta-box with an MPEG-7 handler type is used at the file level, then the

/**
|
||||
* The <i>The Item Location Box</i> provides a directory of resources in this or
|
||||
* other files, by locating their containing file, their offset within that
|
||||
* file, and their length. Placing this in binary format enables common handling
|
||||
* of this data, even by systems which do not understand the particular metadata
|
||||
* system (handler) used. For example, a system might integrate all the
|
||||
* externally referenced metadata resources into one file, re-adjusting file
|
||||
* offsets and file references accordingly.
|
||||
*
|
||||
* Items may be stored fragmented into extents, e.g. to enable interleaving. An
|
||||
* extent is a contiguous subset of the bytes of the resource; the resource is
|
||||
* formed by concatenating the extents. If only one extent is used then either
|
||||
* or both of the offset and length may be implied:
|
||||
*
|
||||
* o If the offset is not identified (the field has a length of zero), then
|
||||
* the beginning of the file (offset 0) is implied.
|
||||
* o If the length is not specified, or specified as zero, then the entire
|
||||
* file length is implied. References into the same file as this metadata,
|
||||
* or items divided into more than one extent, should have an explicit
|
||||
* offset and length, or use a MIME type requiring a different
|
||||
* interpretation of the file, to avoid infinite recursion.
|
||||
*
|
||||
* The size of the item is the sum of the extentLengths. Note: extents may be
|
||||
* interleaved with the chunks defined by the sample tables of tracks.
|
||||
*
|
||||
* The dataReferenceIndex may take the value 0, indicating a reference into the
|
||||
* same file as this metadata, or an index into the dataReference table.
|
||||
*
|
||||
* Some referenced data may itself use offset/length techniques to address
|
||||
* resources within it (e.g. an MP4 file might be included in this way).
|
||||
* Normally such offsets are relative to the beginning of the containing file.
|
||||
* The field base offset provides an additional offset for offset calculations
|
||||
* within that contained data. For example, if an MP4 file is included within a
|
||||
* file formatted to this specification, then normally data-offsets within that
|
||||
* MP4 section are relative to the beginning of file; baseOffset adds to those
|
||||
* offsets.

/**
|
||||
* The <i>IPMP Information Box</i> contains IPMP Descriptors which document the
|
||||
* protection applied to the stream.
|
||||
*
|
||||
* IPMP_Descriptor is defined in 14496-1. This is a part of the MPEG-4 object
|
||||
* descriptors (OD) that describe how an object can be accessed and decoded.
|
||||
* Here, in the ISO Base Media File Format, IPMP Descriptor can be carried
|
||||
* directly in IPMP Information Box without the need for OD stream.
|
||||
*
|
||||
* The presence of IPMP Descriptor in this box indicates the associated media
|
||||
* stream is protected by the IPMP Tool described in the IPMP Descriptor.
|
||||
*
|
||||
* Each IPMP_Descriptor has an IPMP_ToolID, which identifies the required IPMP
|
||||
* tool for protection. An independent registration authority (RA) is used so
|
||||
* any party can register its own IPMP Tool and identify this without
|
||||
* collisions.
|
||||
*
|
||||
* The IPMP_Descriptor carries IPMP information for one or more IPMP Tool
|
||||
* instances, it includes but not limited to IPMP Rights Data, IPMP Key Data,
|
||||
* Tool Configuration Data, etc.
|
||||
*
|
||||
* More than one IPMP Descriptors can be carried in this box if this media
|
||||
* stream is protected by more than one IPMP Tools.

* 1) does this sample depend on others (is it an I-picture)?
|
||||
* 2) do no other samples depend on this one?
|
||||
* 3) does this sample contain multiple (redundant) encodings of the data at
|
||||
* this time-instant (possibly with different dependencies)?
|
||||
*
|
||||
* In the absence of this table:
|
||||
* 1) the sync sample table answers the first question; in most video codecs,
|
||||
* I-pictures are also sync points,
|
||||
* 2) the dependency of other samples on this one is unknown.
|
||||
* 3) the existence of redundant coding is unknown.
|
||||
*
|
||||
* When performing trick modes, such as fast-forward, it is possible to use the
|
||||
* first piece of information to locate independently decodable samples.
|
||||
* Similarly, when performing random access, it may be necessary to locate the
|
||||
* previous sync point or random access recovery point, and roll-forward from
|
||||
* the sync point or the pre-roll starting point of the random access recovery
|
||||
* point to the desired point. While rolling forward, samples on which no others
|
||||
* depend need not be retrieved or decoded.
|
||||
*
|
||||
* The value of sampleIsDependedOn is independent of the existence of redundant
|
||||
* codings. However, a redundant coding may have different dependencies from the
|
||||
* primary coding; if redundant codings are available, the value of
|

* sampleDependsOn documents only the primary coding.

* The <i>Shadow Sync Sample Box</i> table provides an optional set of sync
|
||||
* samples that can be used when seeking or for similar purposes. In normal
|
||||
* forward play they are ignored.
|
||||
*
|
||||
* Each entry in the Shadow Sync Table consists of a pair of sample numbers. The
|
||||
* first entry (shadowedSampleNumber) indicates the number of the sample that a
|
||||
* shadow sync will be defined for. This should always be a non-sync sample
|
||||
* (e.g. a frame difference). The second sample number (syncSampleNumber)
|
||||
* indicates the sample number of the sync sample (i.e. key frame) that can be
|
||||
* used when there is a random access at, or before, the shadowedSampleNumber.
|
||||
*
|
||||
* The shadow sync samples are normally placed in an area of the track that is
|
||||
* not presented during normal play (edited out by means of an edit list),
|
||||
* though this is not a requirement. The shadow sync table can be ignored and
|
||||
* the track will play (and seek) correctly if it is ignored (though perhaps not
|
||||
* optimally).
|
||||
*
|
||||
* The Shadow Sync Sample replaces, not augments, the sample that it shadows
|
||||
* (i.e. the next sample sent is shadowedSampleNumber+1). The shadow sync sample
|
||||
* is treated as if it occurred at the time of the sample it shadows, having the
|
||||
* duration of the sample it shadows.
|
||||
*
|
||||
* Hinting and transmission might become more complex if a shadow sample is used
|
||||
* also as part of normal playback, or is used more than once as a shadow. In
|
||||
* this case the hint track might need separate shadow syncs, all of which can
|
||||
* get their media data from the one shadow sync in the media track, to allow

||||
* for the different time-stamps etc. needed in their headers.
