+
+3. Distribution Obligations.
+
+ 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
+ only do in order to apply it to code which is not already Covered Code
+ 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.)
+
+7. DISCLAIMER OF WARRANTY.
+
+ COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
+ WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+ WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF
+ DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
+ THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE

+ YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE
+ COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER
+ OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
+ ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
+
+8. TERMINATION.
+
+ 8.1. This License and the rights granted hereunder will terminate
+ automatically if You fail to comply with terms herein and fail to cure
+ such breach within 30 days of becoming aware of the breach. All
+ 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,

+
+MP4V2 LIBRARY INTERNALS
+=======================
+
+This document provides an overview of the interals 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.
