# FFmpeg, version 7.1.3

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles, and related metadata.

The FFmpeg media backend uses the FFmpeg framework. FFmpeg is licensed under LGPLv2.1 or later versions of the licenses. Note that, while FFmpeg also features some optional components available under GPL or LGPLv3, the binaries that ship with Qt in the online installer do not contain these components. Build scripts for the prebuilt FFmpeg binaries can be found in the Qt git repository. See the FFmpeg licensing page for further details.

The sources can be found in qtmultimedia/src/3rdparty/ffmpeg.

     Everyone is permitted to copy and distribute verbatim copies of this license
     document, but changing it is not allowed.

     [This is the first released version of the Lesser GPL. It also counts as the
     successor of the GNU Library Public License, version 2, hence the version
     number 2.1.]

     Preamble

     The licenses for most software are designed to take away your freedom to share
     and change it. By contrast, the GNU General Public Licenses are intended to
     guarantee your freedom to share and change free software--to make sure the
     software is free for all its users.

     This license, the Lesser General Public License, applies to some specially
     designated software packages--typically libraries--of the Free Software Foundation
     and other authors who decide to use it. You can use it too, but we suggest
     you first think carefully about whether this license or the ordinary General
     Public License is the better strategy to use in any particular case, based
     on the explanations below.

     When we speak of free software, we are referring to freedom of use, not price.
     Our General Public Licenses are designed to make sure that you have the freedom
     to distribute copies of free software (and charge for this service if you
     wish); that you receive source code or can get it if you want it; that you
     can change the software and use pieces of it in new free programs; and that
     you are informed that you can do these things.

     To protect your rights, we need to make restrictions that forbid distributors
     to deny you these rights or to ask you to surrender these rights. These restrictions
     translate to certain responsibilities for you if you distribute copies of
     the library or if you modify it.

     For example, if you distribute copies of the library, whether gratis or for
     a fee, you must give the recipients all the rights that we gave you. You must
     make sure that they, too, receive or can get the source code. If you link
     other code with the library, you must provide complete object files to the
     recipients, so that they can relink them with the library after making changes
     to the library and recompiling it. And you must show them these terms so they
     know their rights.

     We protect your rights with a two-step method: (1) we copyright the library,
     and (2) we offer you this license, which gives you legal permission to copy,
     distribute and/or modify the library.

     To protect each distributor, we want to make it very clear that there is no
     warranty for the free library. Also, if the library is modified by someone
     else and passed on, the recipients should know that what they have is not
     the original version, so that the original author's reputation will not be
     affected by problems that might be introduced by others.

     Finally, software patents pose a constant threat to the existence of any free
     program. We wish to make sure that a company cannot effectively restrict the
     users of a free program by obtaining a restrictive license from a patent holder.
     Therefore, we insist that any patent license obtained for a version of the
     library must be consistent with the full freedom of use specified in this
     license.

     Most GNU software, including some libraries, is covered by the ordinary GNU
     General Public License. This license, the GNU Lesser General Public License,
     applies to certain designated libraries, and is quite different from the ordinary
     General Public License. We use this license for certain libraries in order
     to permit linking those libraries into non-free programs.

     When a program is linked with a library, whether statically or using a shared
     library, the combination of the two is legally speaking a combined work, a
     derivative of the original library. The ordinary General Public License therefore
     permits such linking only if the entire combination fits its criteria of freedom.
     The Lesser General Public License permits more lax criteria for linking other
     code with the library.

     We call this license the "Lesser" General Public License because it does Less
     to protect the user's freedom than the ordinary General Public License. It
     also provides other free software developers Less of an advantage over competing
     non-free programs. These disadvantages are the reason we use the ordinary
     General Public License for many libraries. However, the Lesser license provides
     advantages in certain special circumstances.

     For example, on rare occasions, there may be a special need to encourage the
     widest possible use of a certain library, so that it becomes a de-facto standard.
     To achieve this, non-free programs must be allowed to use the library. A more
     frequent case is that a free library does the same job as widely used non-free
     libraries. In this case, there is little to gain by limiting the free library
     to free software only, so we use the Lesser General Public License.

     In other cases, permission to use a particular library in non-free programs
     enables a greater number of people to use a large body of free software. For
     example, permission to use the GNU C Library in non-free programs enables
     many more people to use the whole GNU operating system, as well as its variant,
     the GNU/Linux operating system.

     Although the Lesser General Public License is Less protective of the users'
     freedom, it does ensure that the user of a program that is linked with the
     Library has the freedom and the wherewithal to run that program using a modified
     version of the Library.

     The precise terms and conditions for copying, distribution and modification
     follow. Pay close attention to the difference between a "work based on the
     library" and a "work that uses the library". The former contains code derived
     from the library, whereas the latter must be combined with the library in
     order to run.

     TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

     0. This License Agreement applies to any software library or other program
     which contains a notice placed by the copyright holder or other authorized
     party saying it may be distributed under the terms of this Lesser General
     Public License (also called "this License"). Each licensee is addressed as
     "you".

     A "library" means a collection of software functions and/or data prepared
     so as to be conveniently linked with application programs (which use some
     of those functions and data) to form executables.

     The "Library", below, refers to any such software library or work which has
     been distributed under these terms. A "work based on the Library" means either
     the Library or any derivative work under copyright law: that is to say, a
     work containing the Library or a portion of it, either verbatim or with modifications
     and/or translated straightforwardly into another language. (Hereinafter, translation
     is included without limitation in the term "modification".)

     "Source code" for a work means the preferred form of the work for making modifications
     to it. For a library, complete source code means all the source code for all
     modules it contains, plus any associated interface definition files, plus
     the scripts used to control compilation and installation of the library.

     Activities other than copying, distribution and modification are not covered
     by this License; they are outside its scope. The act of running a program
     using the Library is not restricted, and output from such a program is covered
     only if its contents constitute a work based on the Library (independent of
     the use of the Library in a tool for writing it). Whether that is true depends
     on what the Library does and what the program that uses the Library does.

     1. You may copy and distribute verbatim copies of the Library's complete source
     code as you receive it, in any medium, provided that you conspicuously and
     appropriately publish on each copy an appropriate copyright notice and disclaimer
     of warranty; keep intact all the notices that refer to this License and to
     the absence of any warranty; and distribute a copy of this License along with
     the Library.

     You may charge a fee for the physical act of transferring a copy, and you
     may at your option offer warranty protection in exchange for a fee.

     2. You may modify your copy or copies of the Library or any portion of it,
     thus forming a work based on the Library, and copy and distribute such modifications
     or work under the terms of Section 1 above, provided that you also meet all
     of these conditions:

           a) The modified work must itself be a software library.

     b) You must cause the files modified to carry prominent notices stating that
     you changed the files and the date of any change.

     c) You must cause the whole of the work to be licensed at no charge to all
     third parties under the terms of this License.

     d) If a facility in the modified Library refers to a function or a table of
     data to be supplied by an application program that uses the facility, other
     than as an argument passed when the facility is invoked, then you must make
     a good faith effort to ensure that, in the event an application does not supply
     such function or table, the facility still operates, and performs whatever
     part of its purpose remains meaningful.

     (For example, a function in a library to compute square roots has a purpose
     that is entirely well-defined independent of the application. Therefore, Subsection
     2d requires that any application-supplied function or table used by this function
     must be optional: if the application does not supply it, the square root function
     must still compute square roots.)

     These requirements apply to the modified work as a whole. If identifiable
     sections of that work are not derived from the Library, and can be reasonably
     considered independent and separate works in themselves, then this License,
     and its terms, do not apply to those sections when you distribute them as
     separate works. But when you distribute the same sections as part of a whole
     which is a work based on the Library, the distribution of the whole must be
     on the terms of this License, whose permissions for other licensees extend
     to the entire whole, and thus to each and every part regardless of who wrote
     it.

     Thus, it is not the intent of this section to claim rights or contest your
     rights to work written entirely by you; rather, the intent is to exercise
     the right to control the distribution of derivative or collective works based
     on the Library.

     In addition, mere aggregation of another work not based on the Library with
     the Library (or with a work based on the Library) on a volume of a storage
     or distribution medium does not bring the other work under the scope of this
     License.

     3. You may opt to apply the terms of the ordinary GNU General Public License
     instead of this License to a given copy of the Library. To do this, you must
     alter all the notices that refer to this License, so that they refer to the
     ordinary GNU General Public License, version 2, instead of to this License.
     (If a newer version than version 2 of the ordinary GNU General Public License
     has appeared, then you can specify that version instead if you wish.) Do not
     make any other change in these notices.

     Once this change is made in a given copy, it is irreversible for that copy,
     so the ordinary GNU General Public License applies to all subsequent copies
     and derivative works made from that copy.

     This option is useful when you wish to copy part of the code of the Library
     into a program that is not a library.

     4. You may copy and distribute the Library (or a portion or derivative of
     it, under Section 2) in object code or executable form under the terms of
     Sections 1 and 2 above provided that you accompany it with the complete corresponding
     machine-readable source code, which must be distributed under the terms of
     Sections 1 and 2 above on a medium customarily used for software interchange.

     If distribution of object code is made by offering access to copy from a designated
     place, then offering equivalent access to copy the source code from the same
     place satisfies the requirement to distribute the source code, even though
     third parties are not compelled to copy the source along with the object code.

     5. A program that contains no derivative of any portion of the Library, but
     is designed to work with the Library by being compiled or linked with it,
     is called a "work that uses the Library". Such a work, in isolation, is not
     a derivative work of the Library, and therefore falls outside the scope of
     this License.

     However, linking a "work that uses the Library" with the Library creates an
     executable that is a derivative of the Library (because it contains portions
     of the Library), rather than a "work that uses the library". The executable
     is therefore covered by this License. Section 6 states terms for distribution
     of such executables.

     When a "work that uses the Library" uses material from a header file that
     is part of the Library, the object code for the work may be a derivative work
     of the Library even though the source code is not. Whether this is true is
     especially significant if the work can be linked without the Library, or if
     the work is itself a library. The threshold for this to be true is not precisely
     defined by law.

     If such an object file uses only numerical parameters, data structure layouts
     and accessors, and small macros and small inline functions (ten lines or less
     in length), then the use of the object file is unrestricted, regardless of
     whether it is legally a derivative work. (Executables containing this object
     code plus portions of the Library will still fall under Section 6.)

     Otherwise, if the work is a derivative of the Library, you may distribute
     the object code for the work under the terms of Section 6. Any executables
     containing that work also fall under Section 6, whether or not they are linked
     directly with the Library itself.

     6. As an exception to the Sections above, you may also combine or link a "work
     that uses the Library" with the Library to produce a work containing portions
     of the Library, and distribute that work under terms of your choice, provided
     that the terms permit modification of the work for the customer's own use
     and reverse engineering for debugging such modifications.

     You must give prominent notice with each copy of the work that the Library
     is used in it and that the Library and its use are covered by this License.
     You must supply a copy of this License. If the work during execution displays
     copyright notices, you must include the copyright notice for the Library among
     them, as well as a reference directing the user to the copy of this License.
     Also, you must do one of these things:

     a) Accompany the work with the complete corresponding machine-readable source
     code for the Library including whatever changes were used in the work (which
     must be distributed under Sections 1 and 2 above); and, if the work is an
     executable linked with the Library, with the complete machine-readable "work
     that uses the Library", as object code and/or source code, so that the user
     can modify the Library and then relink to produce a modified executable containing
     the modified Library. (It is understood that the user who changes the contents
     of definitions files in the Library will not necessarily be able to recompile
     the application to use the modified definitions.)

     b) Use a suitable shared library mechanism for linking with the Library. A
     suitable mechanism is one that (1) uses at run time a copy of the library
     already present on the user's computer system, rather than copying library
     functions into the executable, and (2) will operate properly with a modified
     version of the library, if the user installs one, as long as the modified
     version is interface-compatible with the version that the work was made with.

     c) Accompany the work with a written offer, valid for at least three years,
     to give the same user the materials specified in Subsection 6a, above, for
     a charge no more than the cost of performing this distribution.

     d) If distribution of the work is made by offering access to copy from a designated
     place, offer equivalent access to copy the above specified materials from
     the same place.

     e) Verify that the user has already received a copy of these materials or
     that you have already sent this user a copy.

     For an executable, the required form of the "work that uses the Library" must
     include any data and utility programs needed for reproducing the executable
     from it. However, as a special exception, the materials to be distributed
     need not include anything that is normally distributed (in either source or
     binary form) with the major components (compiler, kernel, and so on) of the
     operating system on which the executable runs, unless that component itself
     accompanies the executable.

     It may happen that this requirement contradicts the license restrictions of
     other proprietary libraries that do not normally accompany the operating system.
     Such a contradiction means you cannot use both them and the Library together
     in an executable that you distribute.

     7. You may place library facilities that are a work based on the Library side-by-side
     in a single library together with other library facilities not covered by
     this License, and distribute such a combined library, provided that the separate
     distribution of the work based on the Library and of the other library facilities
     is otherwise permitted, and provided that you do these two things:

     a) Accompany the combined library with a copy of the same work based on the
     Library, uncombined with any other library facilities. This must be distributed
     under the terms of the Sections above.

     b) Give prominent notice with the combined library of the fact that part of
     it is a work based on the Library, and explaining where to find the accompanying
     uncombined form of the same work.

     8. You may not copy, modify, sublicense, link with, or distribute the Library
     except as expressly provided under this License. Any attempt otherwise to
     copy, modify, sublicense, link with, or distribute the Library is void, and
     will automatically terminate your rights under this License. However, parties
     who have received copies, or rights, from you under this License will not
     have their licenses terminated so long as such parties remain in full compliance.

     9. You are not required to accept this License, since you have not signed
     it. However, nothing else grants you permission to modify or distribute the
     Library or its derivative works. These actions are prohibited by law if you
     do not accept this License. Therefore, by modifying or distributing the Library
     (or any work based on the Library), you indicate your acceptance of this License
     to do so, and all its terms and conditions for copying, distributing or modifying
     the Library or works based on it.

     10. Each time you redistribute the Library (or any work based on the Library),
     the recipient automatically receives a license from the original licensor
     to copy, distribute, link with or modify the Library subject to these terms
     and conditions. You may not impose any further restrictions on the recipients'
     exercise of the rights granted herein. You are not responsible for enforcing
     compliance by third parties with this License.

     11. If, as a consequence of a court judgment or allegation of patent infringement
     or for any other reason (not limited to patent issues), conditions are imposed
     on you (whether by court order, agreement or otherwise) that contradict the
     conditions of this License, they do not excuse you from the conditions of
     this License. If you cannot distribute so as to satisfy simultaneously your
     obligations under this License and any other pertinent obligations, then as
     a consequence you may not distribute the Library at all. For example, if a
     patent license would not permit royalty-free redistribution of the Library
     by all those who receive copies directly or indirectly through you, then the
     only way you could satisfy both it and this License would be to refrain entirely
     from distribution of the Library.

     If any portion of this section is held invalid or unenforceable under any
     particular circumstance, the balance of the section is intended to apply,
     and the section as a whole is intended to apply in other circumstances.

     It is not the purpose of this section to induce you to infringe any patents
     or other property right claims or to contest validity of any such claims;
     this section has the sole purpose of protecting the integrity of the free
     software distribution system which is implemented by public license practices.
     Many people have made generous contributions to the wide range of software
     distributed through that system in reliance on consistent application of that
     system; it is up to the author/donor to decide if he or she is willing to
     distribute software through any other system and a licensee cannot impose
     that choice.

     This section is intended to make thoroughly clear what is believed to be a
     consequence of the rest of this License.

     12. If the distribution and/or use of the Library is restricted in certain
     countries either by patents or by copyrighted interfaces, the original copyright
     holder who places the Library under this License may add an explicit geographical
     distribution limitation excluding those countries, so that distribution is
     permitted only in or among countries not thus excluded. In such case, this
     License incorporates the limitation as if written in the body of this License.

     13. The Free Software Foundation may publish revised and/or new versions of
     the Lesser General Public License from time to time. Such new versions will
     be similar in spirit to the present version, but may differ in detail to address
     new problems or concerns.

     Each version is given a distinguishing version number. If the Library specifies
     a version number of this License which applies to it and "any later version",
     you have the option of following the terms and conditions either of that version
     or of any later version published by the Free Software Foundation. If the
     Library does not specify a license version number, you may choose any version
     ever published by the Free Software Foundation.

     14. If you wish to incorporate parts of the Library into other free programs
     whose distribution conditions are incompatible with these, write to the author
     to ask for permission. For software which is copyrighted by the Free Software
     Foundation, write to the Free Software Foundation; we sometimes make exceptions
     for this. Our decision will be guided by the two goals of preserving the free
     status of all derivatives of our free software and of promoting the sharing
     and reuse of software generally.

        NO WARRANTY

     15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
     THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
     STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY
     "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
     BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
     FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE
     OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
     THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

     16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
     WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
     THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
     GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
     OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
     OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
     OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
     HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
     END OF TERMS AND CONDITIONS

     How to Apply These Terms to Your New Libraries

     If you develop a new library, and you want it to be of the greatest possible
     use to the public, we recommend making it free software that everyone can
     redistribute and change. You can do so by permitting redistribution under
     these terms (or, alternatively, under the terms of the ordinary General Public
     License).

     To apply these terms, attach the following notices to the library. It is safest
     to attach them to the start of each source file to most effectively convey
     the exclusion of warranty; and each file should have at least the "copyright"
     line and a pointer to where the full notice is found.

     <one line to give the library's name and an idea of what it does.>

     Copyright (C) <year> <name of author>

     2.1. Grants

     Each Contributor hereby grants You a world-wide, royalty-free,
     non-exclusive license:

     (a) under intellectual property rights (other than patent or trademark)
         Licensable by such Contributor to use, reproduce, make available,
         modify, display, perform, distribute, and otherwise exploit its
         Contributions, either on an unmodified basis, with Modifications, or

     (b) under Patent Claims of such Contributor to make, use, sell, offer
         for sale, have made, import, and otherwise transfer either its
         Contributions or its Contributor Version.

     2.2. Effective Date

     The licenses granted in Section 2.1 with respect to any Contribution
     become effective for each Contribution on the date the Contributor first
     distributes such Contribution.

     2.3. Limitations on Grant Scope

     The licenses granted in this Section 2 are the only rights granted under
     this License. No additional rights or licenses will be implied from the
     distribution or licensing of Covered Software under this License.
     Notwithstanding Section 2.1(b) above, no patent license is granted by a
     Contributor:

     (a) for any code that a Contributor has removed from Covered Software;
         or

     (b) for infringements caused by: (i) Your and any other third party's
         modifications of Covered Software, or (ii) the combination of its
         Contributions with other software (except as part of its Contributor
         Version); or

     (c) under Patent Claims infringed by Covered Software in the absence of
         its Contributions.

     This License does not grant any rights in the trademarks, service marks,
     or logos of any Contributor (except as may be necessary to comply with
     the notice requirements in Section 3.4).

     2.4. Subsequent Licenses

     No Contributor makes additional grants as a result of Your choice to
     distribute the Covered Software under a subsequent version of this
     License (see Section 10.2) or under the terms of a Secondary License (if
     permitted under the terms of Section 3.3).

     2.5. Representation

     Each Contributor represents that the Contributor believes its
     Contributions are its original creation(s) or it has sufficient rights
     to grant the rights to its Contributions conveyed by this License.

     2.6. Fair Use

     This License is not intended to limit any rights You have under
     applicable copyright doctrines of fair use, fair dealing, or other
     equivalents.

     2.7. Conditions

     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
     in Section 2.1.

     3. Responsibilities
     -------------------

     3.1. Distribution of Source Form

     All distribution of Covered Software in Source Code Form, including any
     Modifications that You create or to which You contribute, must be under
     the terms of this License. You must inform recipients that the Source
     Code Form of the Covered Software is governed by the terms of this
     License, and how they can obtain a copy of this License. You may not
     attempt to alter or restrict the recipients' rights in the Source Code
     Form.

     3.2. Distribution of Executable Form

     If You distribute Covered Software in Executable Form then:

     (a) such Covered Software must also be made available in Source Code
         Form, as described in Section 3.1, and You must inform recipients of
         the Executable Form how they can obtain a copy of such Source Code
         Form by reasonable means in a timely manner, at a charge no more
         than the cost of distribution to the recipient; and

     (b) You may distribute such Executable Form under the terms of this
         License, or sublicense it under different terms, provided that the
         license for the Executable Form does not attempt to limit or alter
         the recipients' rights in the Source Code Form under this License.

     3.3. Distribution of a Larger Work

     You may create and distribute a Larger Work under terms of Your choice,
     provided that You also comply with the requirements of this License for
     the Covered Software. If the Larger Work is a combination of Covered
     Software with a work governed by one or more Secondary Licenses, and the
     Covered Software is not Incompatible With Secondary Licenses, this
     License permits You to additionally distribute such Covered Software
     under the terms of such Secondary License(s), so that the recipient of
     the Larger Work may, at their option, further distribute the Covered
     Software under the terms of either this License or such Secondary
     License(s).

     3.4. Notices

     You may not remove or alter the substance of any license notices
     (including copyright notices, patent notices, disclaimers of warranty,
     or limitations of liability) contained within the Source Code Form of
     the Covered Software, except that You may alter any license notices to
     the extent required to remedy known factual inaccuracies.

     3.5. Application of Additional Terms

     You may choose to offer, and to charge a fee for, warranty, support,
     indemnity or liability obligations to one or more recipients of Covered
     Software. However, You may do so only on Your own behalf, and not on
     behalf of any Contributor. You must make it absolutely clear that any
     such warranty, support, indemnity, or liability obligation is offered by
     You alone, and You hereby agree to indemnify every Contributor for any
     liability incurred by such Contributor as a result of warranty, support,
     indemnity or liability terms You offer. You may include additional
     disclaimers of warranty and limitations of liability specific to any
     jurisdiction.

     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 Software 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 placed in a text file included with all distributions of the Covered
     Software under this License. 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. Termination
     --------------

     5.1. The rights granted under this License will terminate automatically
     if You fail to comply with any of its terms. However, if You become
     compliant, then the rights granted under this License from a particular
     Contributor are reinstated (a) provisionally, unless and until such
     Contributor explicitly and finally terminates Your grants, and (b) on an
     ongoing basis, if such Contributor fails to notify You of the
     non-compliance by some reasonable means prior to 60 days after You have
     come back into compliance. Moreover, Your grants from a particular
     Contributor are reinstated on an ongoing basis if such Contributor
     notifies You of the non-compliance by some reasonable means, this is the
     first time You have received notice of non-compliance with this License
     from such Contributor, and You become compliant prior to 30 days after
     Your receipt of the notice.

     5.2. If You initiate litigation against any entity by asserting a patent
     infringement claim (excluding declaratory judgment actions,
     counter-claims, and cross-claims) alleging that a Contributor Version
     directly or indirectly infringes any patent, then the rights granted to
     You by any and all Contributors for the Covered Software under Section
     2.1 of this License shall terminate.

     5.3. In the event of termination under Sections 5.1 or 5.2 above, all
     end user license agreements (excluding distributors and resellers) which
     have been validly granted by You or Your distributors under this License
     prior to termination shall survive termination.

     *  Covered Software is provided under this License on an "as is"       *
     *  basis, without warranty of any kind, either expressed, implied, or  *
     *  statutory, including, without limitation, warranties that the       *

     *  Should any Covered Software prove defective in any respect, You     *
     *  (not any Contributor) assume the cost of any necessary servicing,   *
     *  repair, or correction. This disclaimer of warranty constitutes an   *

     *  authorized under this License except under this disclaimer.         *
     *                                                                      *

     *  Under no circumstances and under no legal theory, whether tort      *
     *  (including negligence), contract, or otherwise, shall any           *

     *  special, incidental, or consequential damages of any character      *
     *  including, without limitation, damages for lost profits, loss of    *

     *  limitation of liability shall not apply to liability for death or   *

     *  extent applicable law prohibits such limitation. Some               *

     *  incidental or consequential damages, so this exclusion and          *

     ************************************************************************

     8. Litigation
     -------------

     Any litigation relating to this License may be brought only in the
     courts of a jurisdiction where the defendant maintains its principal
     place of business and such litigation shall be governed by laws of that
     jurisdiction, without reference to its conflict-of-law provisions.
     Nothing in this Section shall prevent a party's ability to bring
     cross-claims or counter-claims.

     9. Miscellaneous
     ----------------

     This License represents the complete agreement concerning the subject
     matter hereof. If any provision of this License is held to be
     unenforceable, such provision shall be reformed only to the extent
     necessary to make it enforceable. Any law or regulation which provides
     that the language of a contract shall be construed against the drafter
     shall not be used to construe this License against a Contributor.

     10. Versions of the License
     ---------------------------

     10.1. New Versions

     Mozilla Foundation is the license steward. Except as provided in Section
     10.3, no one other than the license steward has the right to modify or
     publish new versions of this License. Each version will be given a
     distinguishing version number.

     10.2. Effect of New Versions

     You may distribute the Covered Software under the terms of the version
     of the License under which You originally received the Covered Software,
     or under the terms of any subsequent version published by the license
     steward.

     10.3. Modified Versions

     If you create software not governed by this License, and you want to
     create a new license for such software, you may create and use a
     modified version of this License if you rename the license and remove
     any references to the name of the license steward (except to note that
     such modified license differs from this License).

     10.4. Distributing Source Code Form that is Incompatible With Secondary
     Licenses

     If You choose to distribute Source Code Form that is Incompatible With
     Secondary Licenses under the terms of this version of the License, the
