/*! * libav.js v6.5.7.1 * * This software is compiled from several sources, the licenses for which are * included herein. * * --- * * ffmpeg: * * Copyright (c) 2000-2024 Fabrice Bellard et al * * GNU LESSER GENERAL PUBLIC LICENSE * Version 2.1, February 1999 * * Copyright (C) 1991, 1999 Free Software Foundation, Inc. * 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA * 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. * * GNU LESSER GENERAL PUBLIC LICENSE * 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 a brief idea of what it does.> * Copyright (C) <year> <name of author> * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public * License as published by the Free Software Foundation; either * version 2.1 of the License, or (at your option) any later version. * * This library is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU * Lesser General Public License for more details. * * You should have received a copy of the GNU Lesser General Public * License along with this library; if not, write to the Free Software * Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA * * Also add information on how to contact you by electronic and paper mail. * * You should also get your employer (if you work as a programmer) or your * school, if any, to sign a "copyright disclaimer" for the library, if * necessary.
