-
- 3.1. Application of License.
- The Modifications which You create or to which You contribute are
- governed by the terms of this License, including without limitation
- Section 2.2. The Source Code version of Covered Code may be
- distributed only under the terms of this License or a future version
- of this License released under Section 6.1, and You must include a
- copy of this License with every copy of the Source Code You
- distribute. You may not offer or impose any terms on any Source Code
- version that alters or restricts the applicable version of this
- License or the recipients' rights hereunder. However, You may include
- an additional document offering the additional rights described in
- Section 3.5.
-
- 3.2. Availability of Source Code.
- Any Modification which You create or to which You contribute must be
- made available in Source Code form under the terms of this License
- either on the same media as an Executable version or via an accepted
- Electronic Distribution Mechanism to anyone to whom you made an
- Executable version available; and if made available via Electronic
- Distribution Mechanism, must remain available for at least twelve (12)
- months after the date it initially became available, or at least six
- (6) months after a subsequent version of that particular Modification
- has been made available to such recipients. You are responsible for
- ensuring that the Source Code version remains available even if the
- Electronic Distribution Mechanism is maintained by a third party.
-
- 3.3. Description of Modifications.
- You must cause all Covered Code to which You contribute to contain a
- file documenting the changes You made to create that Covered Code and
- the date of any change. You must include a prominent statement that
- the Modification is derived, directly or indirectly, from Original
- Code provided by the Initial Developer and including the name of the
- Initial Developer in (a) the Source Code, and (b) in any notice in an
- Executable version or related documentation in which You describe the
- origin or ownership of the Covered Code.
-
- 3.4. Intellectual Property Matters
- (a) Third Party Claims.
- If Contributor has knowledge that a license under a third party's
- intellectual property rights is required to exercise the rights
- granted by such Contributor under Sections 2.1 or 2.2,
- Contributor must include a text file with the Source Code
- distribution titled "LEGAL" which describes the claim and the
- party making the claim in sufficient detail that a recipient will
- know whom to contact. If Contributor obtains such knowledge after
- the Modification is made available as described in Section 3.2,
- Contributor shall promptly modify the LEGAL file in all copies
- Contributor makes available thereafter and shall take other steps
- (such as notifying appropriate mailing lists or newsgroups)
- reasonably calculated to inform those who received the Covered
- Code that new knowledge has been obtained.
-
- (b) Contributor APIs.
- If Contributor's Modifications include an application programming
- interface and Contributor has knowledge of patent licenses which
- are reasonably necessary to implement that API, Contributor must
- also include this information in the LEGAL file.
-
- (c) Representations.
- Contributor represents that, except as disclosed pursuant to
- Section 3.4(a) above, Contributor believes that Contributor's
- Modifications are Contributor's original creation(s) and/or
- Contributor has sufficient rights to grant the rights conveyed by
- this License.
-
- 3.5. Required Notices.
- You must duplicate the notice in Exhibit A in each file of the Source
- Code. If it is not possible to put such notice in a particular Source
- Code file due to its structure, then You must include such notice in a
- location (such as a relevant directory) where a user would be likely
- to look for such a notice. If You created one or more Modification(s)
- You may add your name as a Contributor to the notice described in
- Exhibit A. You must also duplicate this License in any documentation
- for the Source Code where You describe recipients' rights or ownership
- rights relating to Covered Code. You may choose to offer, and to
- charge a fee for, warranty, support, indemnity or liability
- obligations to one or more recipients of Covered Code. However, You
- may do so only on Your own behalf, and not on behalf of the Initial
- Developer or any Contributor. You must make it absolutely clear than
- any such warranty, support, indemnity or liability obligation is
- offered by You alone, and You hereby agree to indemnify the Initial
- Developer and every Contributor for any liability incurred by the
- Initial Developer or such Contributor as a result of warranty,
- support, indemnity or liability terms You offer.
-
- 3.6. Distribution of Executable Versions.
- You may distribute Covered Code in Executable form only if the
- requirements of Section 3.1-3.5 have been met for that Covered Code,
- and if You include a notice stating that the Source Code version of
- the Covered Code is available under the terms of this License,
- including a description of how and where You have fulfilled the
- obligations of Section 3.2. The notice must be conspicuously included
- in any notice in an Executable version, related documentation or
- collateral in which You describe recipients' rights relating to the
- Covered Code. You may distribute the Executable version of Covered
- Code or ownership rights under a license of Your choice, which may
- contain terms different from this License, provided that You are in
- compliance with the terms of this License and that the license for the
- Executable version does not attempt to limit or alter the recipient's
- rights in the Source Code version from the rights set forth in this
- License. If You distribute the Executable version under a different
- license You must make it absolutely clear that any terms which differ
- from this License are offered by You alone, not by the Initial
- Developer or any Contributor. You hereby agree to indemnify the
- Initial Developer and every Contributor for any liability incurred by
- the Initial Developer or such Contributor as a result of any such
- terms You offer.
-
- 3.7. Larger Works.
- You may create a Larger Work by combining Covered Code with other code
- not governed by the terms of this License and distribute the Larger
- Work as a single product. In such a case, You must make sure the
- requirements of this License are fulfilled for the Covered Code.
-
-4. Inability to Comply Due to Statute or Regulation.
-
- If it is impossible for You to comply with any of the terms of this
- License with respect to some or all of the Covered Code due to
- statute, judicial order, or regulation then You must: (a) comply with
- the terms of this License to the maximum extent possible; and (b)
- describe the limitations and the code they affect. Such description
- must be included in the LEGAL file described in Section 3.4 and must
- be included with all distributions of the Source Code. Except to the
- extent prohibited by statute or regulation, such description must be
- sufficiently detailed for a recipient of ordinary skill to be able to
- understand it.
-
-5. Application of this License.
-
- This License applies to code to which the Initial Developer has
- attached the notice in Exhibit A and to related Covered Code.
-
-6. Versions of the License.
-
- 6.1. New Versions.
- Netscape Communications Corporation ("Netscape") may publish revised- and/or new versions of the License from time to time. Each version
- will be given a distinguishing version number.
-
- 6.2. Effect of New Versions.
- Once Covered Code has been published under a particular version of the
- License, You may always continue to use it under the terms of that
- version. You may also choose to use such Covered Code under the terms
- of any subsequent version of the License published by Netscape. No one
- other than Netscape has the right to modify the terms applicable to
- Covered Code created under this License.
-
- 6.3. Derivative Works.
- If You create or use a modified version of this License (which you may

- governed by this License), You must (a) rename Your license so that
- the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape",
- "MPL", "NPL" or any confusingly similar phrase do not appear in your
- license (except to note that your license differs from this License)
- and (b) otherwise make it clear that Your version of the license
- contains terms which differ from the Mozilla Public License and
- Netscape Public License. (Filling in the name of the Initial
- Developer, Original Code or Contributor in the notice described in
- Exhibit A shall not of themselves be deemed to be modifications of
- this License.)

- OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
- ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
-
-8. TERMINATION.
-

- sublicenses to the Covered Code which are properly granted shall
- survive any termination of this License. Provisions which, by their
- nature, must remain in effect beyond the termination of this License
- shall survive.
-
- 8.2. If You initiate litigation by asserting a patent infringement
- claim (excluding declatory judgment actions) against Initial Developer
- or a Contributor (the Initial Developer or Contributor against whom
- You file such action is referred to as "Participant") alleging that:
-
- (a) such Participant's Contributor Version directly or indirectly
- infringes any patent, then any and all rights granted by such
- Participant to You under Sections 2.1 and/or 2.2 of this License
- shall, upon 60 days notice from Participant terminate prospectively,
- unless if within 60 days after receipt of notice You either: (i)
- agree in writing to pay Participant a mutually agreeable reasonable
- royalty for Your past and future use of Modifications made by such
- Participant, or (ii) withdraw Your litigation claim with respect to
- the Contributor Version against such Participant. If within 60 days
- of notice, a reasonable royalty and payment arrangement are not
- mutually agreed upon in writing by the parties or the litigation claim
- is not withdrawn, the rights granted by Participant to You under
- Sections 2.1 and/or 2.2 automatically terminate at the expiration of
- the 60 day notice period specified above.
-
- (b) any software, hardware, or device, other than such Participant's
- Contributor Version, directly or indirectly infringes any patent, then
- any rights granted to You by such Participant under Sections 2.1(b)
- and 2.2(b) are revoked effective as of the date You first made, used,
- sold, distributed, or had made, Modifications made by that
- Participant.
-
- 8.3. If You assert a patent infringement claim against Participant
- alleging that such Participant's Contributor Version directly or
- indirectly infringes any patent where such claim is resolved (such as
- by license or settlement) prior to the initiation of patent
- infringement litigation, then the reasonable value of the licenses
- granted by such Participant under Sections 2.1 or 2.2 shall be taken
- into account in determining the amount or value of any payment or
- license.
-
- 8.4. In the event of termination under Sections 8.1 or 8.2 above,
- all end user license agreements (excluding distributors and resellers)
- which have been validly granted by You or any distributor hereunder
- prior to termination shall survive termination.
-
-9. LIMITATION OF LIABILITY.
-
- UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
- (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL
- DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE,

- RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
- PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
- EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO
- THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
-
-10. U.S. GOVERNMENT END USERS.
-
- The Covered Code is a "commercial item," as that term is defined in
- 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
- software" and "commercial computer software documentation," as such
- terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48

-MP4V2 LIBRARY INTERNALS
-=======================
-
-This document provides an overview of the internals of the mp4v2 library
-to aid those who wish to modify and extend it. Before reading this document,
-I recommend familiarizing yourself with the MP4 (or Quicktime) file format
-standard and the mp4v2 library API. The API is described in a set of man pages
-in mpeg4ip/doc/mp4v2, or if you prefer by looking at mp4.h.
-
-All the library code is written in C++, however the library API follows uses
-C calling conventions hence is linkable by both C and C++ programs. The
-library has been compiled and used on Linux, BSD, Windows, and Mac OS X.
-Other than libc, the library has no external dependencies, and hence can
-be used independently of the mpeg4ip package if desired. The library is
-used for both real-time recording and playback in mpeg4ip, and its runtime
-performance is up to those tasks. On the IA32 architecture compiled with gcc,
-the stripped library is approximately 600 KB code and initialized data.
-
-It is useful to think of the mp4v2 library as consisting of four layers:
-infrastructure, file format, generic tracks, and type specific track helpers.
-A description of each layer follows, from the fundamental to the optional.
-
-
-Infrastructure
-==============
-
-The infrastructure layer provides basic file I/O, memory allocation,
-error handling, string utilities, and protected arrays. The source files
-for this layer are mp4file_io, mp4util, and mp4array.
-
-Note that the array classes uses preprocessor macros instead of C++
-templates. The rationale for this is to increase portability given the
-sometimes incomplete support by some compilers for templates.
-
-
-File Format
-===========
-
-The file format layer provides the translation from the on-disk MP4 file
-format to in-memory C++ structures and back to disk. It is intended
-to exactly match the MP4 specification in syntax and semantics. It
-represents the majority of the code.
-
-There are three key structures at the file format layer: atoms, properties,
-and descriptors.
-
-Atoms are the primary containers within an mp4 file. They can contain
-any combination of properties, other atoms, or descriptors.
-
-The mp4atom files contain the base class for all the atoms, and provide
-generic functions that cover most cases. However, each atom has it's own
-subclass contained in file atom_<name>.cpp, where <name> is the four
-letter name of the atom defined in the MP4 specification. Typically this
-atom file just specifies the properties of the atom or the possible child
-atoms in the case of a container atom. In more specialized cases the atom
-specific file provides routines to initialize, read, or write the atom.
-
-Properties are the atomic pieces of information. The basic types of
-properties are integers, floats, strings, and byte arrays. For integers
-and floats there are subclasses that represent the different storage sizes,
-e.g. 8, 16, 24, 32, and 64 bit integers. For strings, there is 1 property
-class with a number of options regarding exact storage details, e.g. null
-terminated, fixed length, counted.
-
-For implementation reasons, there are also two special properties, table
-and descriptor, that are actually containers for groups of properties.
-I.e by making these containers provide a property interface much code can
-be written in a generic fashion.
-
-The mp4property files contain all the property related classes.
-
-Descriptors are containers that derive from the MPEG conventions and use
-different encoding rules than the atoms derived from the QuickTime file
-format. This means more use of bitfields and conditional existence with
-an emphasis on bit efficiency at the cost of encoding/decoding complexity.
-Descriptors can contain other descriptors and/or properties.
-
-The mp4descriptor files contain the generic base class for descriptors.
-Also the mp4property files have a descriptor wrapper class that allows a
-descriptor to behave as if it were a property. The specific descriptors
-are implemented as subclasses of the base class descriptor in manner similar
-to that of atoms. The descriptors, ocidescriptors, and qosqualifiers files
-contain these implementations.
-
-Each atom/property/descriptor has a name closely related to that in the
-MP4 specification. The difference being that the mp4v2 library doesn't
-use '-' or '_' in property names and capitalizes the first letter of each
-word, e.g. "thisIsAPropertyName". A complete name specifies the complete
-container path. The names follow the C/C++ syntax for elements and array
-indices.
-
-Examples are:
- "moov.mvhd.duration"
- "moov.trak[2].tkhd.duration"
- "moov.trak[3].minf.mdia.stbl.stsz[101].sampleSize"
-
-Note "*" can be used as a wildcard for an atom name (only). This is most
-useful when dealing with the stsd atom which contains child atoms with
-various names, but shared property names.
-
-Note that internally when performance matters the code looks up a property
-by name once, and then stores the returned pointer to the property class.
-
-
-Generic Tracks
-==============
-
-The two entities at this level are the mp4 file as a whole and the tracks
-which are contained with it. The mp4file and mp4track files contain the
-implementation.
-
-The critical work done by this layer is to map the collection of atoms,
-properties, and descriptors that represent a media track into a useful,
-and consistent set of operations. For example, reading or writing a media
-sample of a track is a relatively simple operation from the library API
-perspective. However there are numerous pieces of information in the mp4
-file that need to be properly used and updated to do this. This layer
-handles all those details.
-
-Given familiarity with the mp4 spec, the code should be straight-forward.
-What may not be immediately obvious are the functions to handle chunks of
-media samples. These exist to allow optimization of the mp4 file layout by
-reordering the chunks on disk to interleave the media sample chunks of
-multiple tracks in time order. (See MP4Optimize API doc).
-
-
-Type Specific Track Helpers
-===========================
-
-This specialized code goes beyond the meta-information about tracks in
-the mp4 file to understanding and manipulating the information in the
-track samples. There are currently two helpers in the library:
-the MPEG-4 Systems Helper, and the RTP Hint Track Helper.
-
-The MPEG-4 Systems Helper is currently limited to creating the OD, BIFS,
-and SDP information about a minimal audio/video scene consistent with
-the Internet Streaming Media Alliance (ISMA) specifications. We will be
-evaluating how best to generalize the library's helper functions for
-MPEG-4 Systems without overburdening the implementation. The code for
-this helper is found in the isma and odcommands files.
-
-The RTP Hint Track Helper is more extensive in its support. The hint
-tracks contain the track packetization information needed to build
-RTP packets for streaming. The library can construct RTP packets based
-on the hint track making RTP based servers significantly easier to write.
-
-All code related to rtp hint tracks is in the rtphint files. It would also
-be useful to look at test/mp4broadcaster and mpeg4ip/server/mp4creator for
-examples of how this part of the library API can be used.
-
-
-Library API
-===========
-
-The library API is defined and implemented in the mp4 files. The API uses
-C linkage conventions, and the mp4.h file adapts itself according to whether
-C or C++ is the compilation mode.
-
-All API calls are implemented in mp4.cpp and basically pass thru's to the
-MP4File member functions. This ensures that the library has internal access
-to the same functions as available via the API. All the calls in mp4.cpp use
-C++ try/catch blocks to protect against any runtime errors in the library.
-Upon error the library will print a diagnostic message if the verbostiy level
-has MP4_DETAILS_ERROR set, and return a distinguished error value, typically
-0 or -1.
-
-The test and util subdirectories contain useful examples of how to
-use the library. Also the mp4creator and mp4live programs within
-mpeg4ip demonstrate more complete usage of the library API.
-
-
-Debugging
-=========
-
-Since mp4 files are fairly complicated, extensive debugging support is
-built into the library. Multi-level diagnostic messages are available
-under the control of a verbosity bitmask described in the API.
-
-Also the library provides the MP4Dump() call which provides an ASCII
-version of the mp4 file meta-information. The mp4dump utilitity is a
-wrapper executable around this function.
-
-The mp4extract program is also provided in the utilities directory
-which is useful for extracting a track from an mp4file and putting the
-media data back into it's own file. It can also extract each sample of
-a track into its own file it that is desired.
-
-When all else fails, mp4 files are amenable to debugging by direct
-examination. Since the atom names are four letter ASCII codes finding
-reference points in a hex dump is feasible. On UNIX, the od command
-is your friend: "od -t x1z -A x [-j 0xXXXXXX] foo.mp4" will print
-a hex and ASCII dump, with hex addresses, starting optionally from
-a specified offset. The library diagnostic messages can provide
-information on where the library is reading or writing.
-
-
-General caveats
-===============
-
-The coding convention is to use the C++ throw operator whenever an
-unrecoverable error occurs. This throw is caught at the API layer
-in mp4.cpp and translated into an error value.
-
-Be careful about indices. Internally, we follow the C/C++ convention
-to use zero-based indices. However the MP4 spec uses one-based indices
-for things like samples and hence the library API uses this convention.

-MP4V2 Library
-=============
-
-This library provides functions to read, create, and modify mp4 files.
-
-The detailed documentation of the library is available as a set of man pages
-in mpeg4ip/doc/mp4v2. The MP4.3 man page gives an overview of the library.
-
-Alternately mp4.h in this directory specifies the complete API.
-
-The file INTERNALS provides an overview of what is happening behind the API.
-Note that although we using C++ object oriented features internally, that's
-all hidden behind a flat C style API (with C linkage conventions).
-
-The test and util subdirectories contain some simple programs that use
-this library.
-
-To use this library in your application, it should be sufficient to:
-
-1) add mpeg4ip/include and mpeg4ip/lib/mp4v2 to your INCLUDE path,
- e.g. gcc -Impeg4ip/include -Impeg4ip/lib/mp4v2 ...
-
-2) add mpeg4ip/lib/mp4v2/libmp4v2.la (or /usr/local/lib/libmp4v2.la)
- e.g. gcc ... -o foo foo.cpp mpeg4ip/lib/mp4v2/libmp4v2.a
-
-3) include mp4.h into your code,
- e.g. #include <mp4.h>

-
- The iTunes tagging seems to support any tag field name
- but there are some predefined fields, also known from the QuickTime format
-
- predefined fields (the ones I know of until now):
- - �nam : Name of the song/movie (string)
- - �ART : Name of the artist/performer (string)
- - �wrt : Name of the writer (string)
- - �alb : Name of the album (string)
- - �day : Year (4 bytes, e.g. "2003") (string)
- - �too : Tool(s) used to create the file (string)
- - �cmt : Comment (string)
- - �gen : Custom genre (string)
- - trkn : Tracknumber (8 byte string)
- 16 bit: empty
- 16 bit: tracknumber
- 16 bit: total tracks on album
- 16 bit: empty
- - disk : Disknumber (8 byte string)
- 16 bit: empty
- 16 bit: disknumber
- 16 bit: total number of disks
- 16 bit: empty
- - gnre : Genre (16 bit genre) (ID3v1 index + 1)
- - cpil : Part of a compilation (1 byte, 1 or 0)
- - tmpo : Tempo in BPM (16 bit)
- - covr : Cover art (xx bytes binary data)
- - ---- : Free form metadata, can have any name and any data
