-If you have a question rather than reporting a bug please go to https://forum.opencv.org where you get much faster responses.
-If you need further assistance please read [How To Contribute](https://github.com/opencv/opencv/wiki/How_to_contribute).
-
-This is a template helping you to create an issue which can be processed as quickly as possible. This is the bug reporting section for the OpenCV library.

-##### Steps to reproduce
-
-<!-- to add code example fence it with triple backticks and optional file extension
-    ```.cpp
-    // C++ code example
-    ```
- or attach as .txt or .zip file
--->
-
-##### Issue submission checklist
-
- - [ ] I report the issue, it's not a question
-   <!--
-   OpenCV team works with forum.opencv.org, Stack Overflow and other communities
-   to discuss problems. Tickets with questions without a real issue statement will be
-   closed.
-   -->
- - [ ] I checked the problem with documentation, FAQ, open issues,
-       forum.opencv.org, Stack Overflow, etc and have not found any solution
-   <!--
-   Places to check:
-   * OpenCV documentation: https://docs.opencv.org
-   * FAQ page: https://github.com/opencv/opencv/wiki/FAQ
-   * OpenCV forum: https://forum.opencv.org
-   * OpenCV issue tracker: https://github.com/opencv/opencv/issues?q=is%3Aissue
-   * Stack Overflow branch: https://stackoverflow.com/questions/tagged/opencv
-   -->
- - [ ] I updated to the latest OpenCV version and the issue is still there
-   <!--
-   master branch for OpenCV 4.x and 3.4 branch for OpenCV 3.x releases.
-   OpenCV team supports only the latest release for each branch.
-   The ticket is closed if the problem is not reproduced with the modern version.
-   -->
- - [ ] There is reproducer code and related data files: videos, images, onnx, etc
-   <!--
-   The best reproducer -- test case for OpenCV that we can add to the library.
-   Recommendations for media files and binary files:
-   * Try to reproduce the issue with images and videos in opencv_extra repository
-     to reduce attachment size
-   * Use PNG for images, if you report some CV related bug, but not image reader
-     issue
-   * Attach the image as an archive to the ticket, if you report some reader issue.
-     Image hosting services compress images and it breaks the repro code.
-   * Provide ONNX file for some public model or ONNX file with random weights,
-     if you report ONNX parsing or handling issue. Architecture details diagram
-     from netron tool can be very useful too. See https://lutzroeder.github.io/netron/

-    This is generator of CLapack subset.
-    The usage:
-
-    1. Make sure you have the special version of f2c installed.
-       Grab it from https://github.com/vpisarev/f2c/tree/for_lapack.
-    2. Download fresh version of Lapack from
-       https://github.com/Reference-LAPACK/lapack.
-       You may choose some specific version or the latest snapshot.
-    3. If necessary, edit "roots" and "banlist" variables in this script, specify the needed and unneeded functions
-    4. From within a working directory run
-
-       $ python3 <opencv_root>/3rdparty/clapack/make_clapack.py <lapack_root>
-       or
-       $ F2C=<path_to_custom_f2c> python3 <opencv_root>/3rdparty/clapack/make_clapack.py <lapack_root>
-
-       it will generate "new_clapack" directory with "include" and "src" subdirectories.
-    5. erase opencv/3rdparty/clapack/src and replace it with new_clapack/src.
-    6. copy new_clapack/include/lapack.h to opencv/3rdparty/clapack/include.
-    7. optionally, edit opencv/3rdparty/clapack/CMakeLists.txt and update CLAPACK_VERSION as needed.
-
-    This is it. Now build it and enjoy.

-
-/* The list of feature flags for ANDROID_CPU_FAMILY_ARM that can be
- * recognized by the library (see note below for 64-bit ARM). Value details
- * are:
- *
- *   VFPv2:
- *     CPU supports the VFPv2 instruction set. Many, but not all, ARMv6 CPUs
- *     support these instructions. VFPv2 is a subset of VFPv3 so this will
- *     be set whenever VFPv3 is set too.
- *
- *   ARMv7:
- *     CPU supports the ARMv7-A basic instruction set.
- *     This feature is mandated by the 'armeabi-v7a' ABI.
- *
- *   VFPv3:
- *     CPU supports the VFPv3-D16 instruction set, providing hardware FPU
- *     support for single and double precision floating point registers.
- *     Note that only 16 FPU registers are available by default, unless
- *     the D32 bit is set too. This feature is also mandated by the
- *     'armeabi-v7a' ABI.
- *
- *   VFP_D32:
- *     CPU VFP optional extension that provides 32 FPU registers,
- *     instead of 16. Note that ARM mandates this feature is the 'NEON'
- *     feature is implemented by the CPU.
- *
- *   NEON:
- *     CPU FPU supports "ARM Advanced SIMD" instructions, also known as
- *     NEON. Note that this mandates the VFP_D32 feature as well, per the
- *     ARM Architecture specification.
- *
- *   VFP_FP16:
- *     Half-width floating precision VFP extension. If set, the CPU
- *     supports instructions to perform floating-point operations on
- *     16-bit registers. This is part of the VFPv4 specification, but
- *     not mandated by any Android ABI.
- *
- *   VFP_FMA:
- *     Fused multiply-accumulate VFP instructions extension. Also part of
- *     the VFPv4 specification, but not mandated by any Android ABI.
- *
- *   NEON_FMA:
- *     Fused multiply-accumulate NEON instructions extension. Optional
- *     extension from the VFPv4 specification, but not mandated by any
- *     Android ABI.
- *
- *   IDIV_ARM:
- *     Integer division available in ARM mode. Only available
- *     on recent CPUs (e.g. Cortex-A15).
- *
- *   IDIV_THUMB2:
- *     Integer division available in Thumb-2 mode. Only available
- *     on recent CPUs (e.g. Cortex-A15).
- *
- *   iWMMXt:
- *     Optional extension that adds MMX registers and operations to an
- *     ARM CPU. This is only available on a few XScale-based CPU designs
- *     sold by Marvell. Pretty rare in practice.
- *
- *   AES:
- *     CPU supports AES instructions. These instructions are only
- *     available for 32-bit applications running on ARMv8 CPU.
- *
- *   CRC32:
- *     CPU supports CRC32 instructions. These instructions are only
- *     available for 32-bit applications running on ARMv8 CPU.
- *
- *   SHA2:
- *     CPU supports SHA2 instructions. These instructions are only
- *     available for 32-bit applications running on ARMv8 CPU.
- *
- *   SHA1:
- *     CPU supports SHA1 instructions. These instructions are only
- *     available for 32-bit applications running on ARMv8 CPU.
- *
- *   PMULL:
- *     CPU supports 64-bit PMULL and PMULL2 instructions. These
- *     instructions are only available for 32-bit applications
- *     running on ARMv8 CPU.
- *
- * If you want to tell the compiler to generate code that targets one of
- * the feature set above, you should probably use one of the following
- * flags (for more details, see technical note at the end of this file):
- *
- *   -mfpu=vfp
- *   -mfpu=vfpv2
- *     These are equivalent and tell GCC to use VFPv2 instructions for
- *     floating-point operations. Use this if you want your code to
- *     run on *some* ARMv6 devices, and any ARMv7-A device supported
- *     by Android.
- *
- *     Generated code requires VFPv2 feature.
- *
- *   -mfpu=vfpv3-d16
- *     Tell GCC to use VFPv3 instructions (using only 16 FPU registers).
- *     This should be generic code that runs on any CPU that supports the
- *     'armeabi-v7a' Android ABI. Note that no ARMv6 CPU supports this.
- *
- *     Generated code requires VFPv3 feature.
- *
- *   -mfpu=vfpv3
- *     Tell GCC to use VFPv3 instructions with 32 FPU registers.
- *     Generated code requires VFPv3|VFP_D32 features.
- *
- *   -mfpu=neon
- *     Tell GCC to use VFPv3 instructions with 32 FPU registers, and
- *     also support NEON intrinsics (see <arm_neon.h>).
- *     Generated code requires VFPv3|VFP_D32|NEON features.
- *
- *   -mfpu=vfpv4-d16
- *     Generated code requires VFPv3|VFP_FP16|VFP_FMA features.
- *
- *   -mfpu=vfpv4
- *     Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32 features.
- *
- *   -mfpu=neon-vfpv4
- *     Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32|NEON|NEON_FMA
- *     features.
- *
- *   -mcpu=cortex-a7
- *   -mcpu=cortex-a15
- *     Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32|
- *                             NEON|NEON_FMA|IDIV_ARM|IDIV_THUMB2
- *     This flag implies -mfpu=neon-vfpv4.
- *
- *   -mcpu=iwmmxt
- *     Allows the use of iWMMXt instrinsics with GCC.
- *
- * IMPORTANT NOTE: These flags should only be tested when
- * android_getCpuFamily() returns ANDROID_CPU_FAMILY_ARM, i.e. this is a
- * 32-bit process.
- *
- * When running a 64-bit ARM process on an ARMv8 CPU,
- * android_getCpuFeatures() will return a different set of bitflags

-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-
-[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.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
-
-  <signature of Ty Coon>, 1 April 1990

-That's all there is to it!

-  (System32 or SysWOW64) or near application binaries (check documentation of "LoadLibrary" Win32 function from MSDN).
-  Or you can specify location of binary file via OPENH264_LIBRARY environment variable.
+4. Now you have working MSYS32 and MSYS64 environments.
+   Launch, one by one, C:\MSYS32\msys\msys.bat and C:\MSYS64\msys\msys.bat to create your home directories.
 
-  If LGPL/GPL software can not be supplied with your OpenCV-based product, simply exclude
-  opencv_videoio_ffmpeg*.dll from your distribution; OpenCV will stay fully functional except for the ability to
-  decode/encode videos using FFMPEG (though, it may still be able to do that using other API,
-  such as Video for Windows, Windows Media Foundation or our self-contained motion jpeg codec).
+4. Download ffmpeg-x.y.z.tar.gz (where x.y.z denotes the actual ffmpeg version).
+   Copy it to C:\MSYS{32|64}\msys\home\<loginname> directory.
 
-  See license.txt for the FFMPEG copyright notice and the licensing terms.
+5. To build 32-bit ffmpeg libraries, run C:\MSYS32\msys\msys.bat and type the following commands:
+
+   5.1. tar -xzf ffmpeg-x.y.z.tar.gz
+   5.2. mkdir build
+   5.3. cd build
+   5.4. ../ffmpeg-x.y.z/configure --enable-w32threads
+   5.5. make
+   5.6. make install
+   5.7. cd /local/lib
+   5.8. strip -g *.a
+
+6. Then repeat the same for 64-bit case. The output libs: libavcodec.a etc. need to be renamed to libavcodec64.a etc.
+
+7. Then, copy all those libs to <opencv>\3rdparty\lib\, copy the headers to <opencv>\3rdparty\include\ffmpeg_.
+
+8. Then, go to <opencv>\3rdparty\ffmpeg, edit make.bat
+   (change paths to the actual paths to your msys32 and msys64 distributions) and then run make.bat

-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-

-
-HarfBuzz started as a text shaping engine but has grown into a
-full font platform — the `ffmpeg` of text shaping.  It primarily
-supports [OpenType][1], but also [Apple Advanced Typography][2].
-
-HarfBuzz shapes the majority of text on modern screens.
-
-HarfBuzz is optimized for robustness, correctness, and performance
-— in that order. Achieve all.
-
-**[Try it live at harfbuzz-world.cc](https://harfbuzz-world.cc/)** — an interactive playground for shaping, subsetting, rasterization, vector output, and GPU rendering, all running in your browser.
-
-Here is a quick map of its components:
-
-### Core libraries
-
-| Library | Description |
-|---------|-------------|
-| **libharfbuzz** | Text shaping, draw API, paint API. Highly configurable (see [CONFIG.md](CONFIG.md)). Optional integration backends compiled in: hb-ft (FreeType), hb-coretext (macOS), hb-uniscribe (Windows), hb-directwrite (Windows), hb-gdi (Windows), hb-glib, hb-graphite2. |
-| **libharfbuzz-subset** | Font subsetting and variable-font instancing. |
-
-### Auxiliary libraries
-
-| Library | Description |
-|---------|-------------|
-| **libharfbuzz-icu** | ICU Unicode integration. |
-| **libharfbuzz-cairo** | Cairo rendering integration. |
-| **libharfbuzz-gobject** | GObject/GI bindings. |
-
-### Experimental libraries
-
-| Library | Description |
-|---------|-------------|
-| **libharfbuzz-raster** | Glyph rasterization to bitmaps, including color fonts. Uses hb-draw and hb-paint. |
-| **libharfbuzz-vector** | Glyph output to vector formats (currently SVG), including color fonts. Uses hb-draw and hb-paint. |
-| **libharfbuzz-gpu** | Encodes glyph outlines for GPU rasterization (Slug algorithm). Provides shader sources in GLSL, WGSL, MSL, and HLSL. [Live demo.](https://harfbuzz.github.io/hb-gpu-demo/) |
-
-Notable missing feature: font hinting (including autohinting)
-is not implemented.  For hinted rasterization, use FreeType or
-Skrifa.
-
-For simplified builds, amalgamated sources are available:
-`harfbuzz.cc` (just libharfbuzz), `harfbuzz-subset.cc` (just
-libharfbuzz-subset), or `harfbuzz-world.cc` (everything, driven
-by a custom `hb-features.h`).  For a live in-browser playground
-plus a worked example of the world.cc single-file build, see
-[harfbuzz-world.cc][26].
-
-### Command-line tools
-
-| Tool | Description |
-|------|-------------|
-| **hb-shape** | Shape text and display glyph output. |
-| **hb-view** | Render shaped text to an image. |
-| **hb-subset** | Subset and optimize fonts. |
-| **hb-info** | Display font metadata. |
-| **hb-raster** | Render glyphs to bitmap images. |
-| **hb-vector** | Render glyphs to vector formats (SVG). |
-| **hb-gpu** | Interactive GPU text rendering. |
-
-The canonical source tree and bug trackers are available on [github][4].
-Both development and user support discussion around HarfBuzz happen on
-[github][4] as well.
-
-For license information, see [COPYING](COPYING).
-
-## API stability
-
-The API that comes with `hb.h` will not change incompatibly. Other, peripheral,
-headers are more likely to go through minor modifications, but again, we do our
-best to never change API in an incompatible way. We will never break the ABI.
-
-The API and ABI are stable even across major version number jumps. In fact,
-current HarfBuzz is API/ABI compatible all the way back to the 0.9.x series.
-If one day we need to break the API/ABI, that would be called a new library.
-
-As such, we bump the major version number only when we add major new features,
-the minor version when there is new API, and the micro version when there
-are bug fixes.
-

-The logo shows حرف‌باز in the IranNastaliq font, on a Damascus
-steel background.
-
-> Background: Originally there was this font format called TrueType. People and
-> companies started calling their type engines all things ending in Type:
-> FreeType, CoolType, ClearType, etc. And then came OpenType, which is the
-> successor of TrueType. So, for my OpenType implementation, I decided to stick
-> with the concept but use the Persian translation. Which is fitting given that
-> Persian is written in the Arabic script, and OpenType is an extension of
-> TrueType that adds support for complex script rendering, and HarfBuzz is an
-> implementation of OpenType text shaping.

-"""
-hb_extract.py -- copy the minimal subset of HarfBuzz sources used by OpenCV.
-
-OpenCV vendors HarfBuzz as a normal static library: every .cc is a separate
-translation unit (no unity / amalgamation build). This script reproduces the
-exact src/ tree that OpenCV ships, from a pristine HarfBuzz checkout.
-
-It does three things beyond a naive copy, all to keep the vendored tree small
-and buildable with OpenCV's configuration (HB_TINY + HB_HAS_RASTER, see
-CMakeLists.txt):
-
-  1. Copies the translation units that upstream `harfbuzz-world.cc` would
-     compile for the requested HB_HAS_* sections -- EXCEPT the ones that build
-     to an empty object under our config (see EMPTY_TUS). It never emits
-     `harfbuzz-world.cc` itself (we compile each .cc directly), and never
-     copies non-TU .cc files found under src/OT|graph (only real TUs from the
-     parsed world.cc lists are copied), so CMake's file(GLOB_RECURSE src/*.cc)
-     picks up exactly the right set.
-
-  2. Prunes headers down to the set actually reachable by #include from the
-     copied TUs (+ the public headers OpenCV includes). This automatically
-     drops the large amount of HarfBuzz src/ that we never compile -- GPU and
-     WASM backends, the subset/repacker graph, platform backends (CoreText/
-     DirectWrite/GDI/Uniscribe/Graphite2/GObject/Cairo), the vector-paint
-     backend, and headers used only by the skipped empty TUs -- without a
-     hardcoded blocklist.
-
-  3. Generates `hb-opencv-config.hh`, the config-override header CMakeLists.txt
-     points HB_CONFIG_OVERRIDE_H at. It re-enables thread-safety (HB_NO_MT) and
-     variable fonts (HB_NO_VAR) that HB_TINY would otherwise switch off. (It
-     does NOT generate upstream's hb-features.h: nothing we compile includes
-     it.)
-
-Usage (to refresh this very directory, just point it at a harfbuzz checkout):
-  python hb_extract.py path/to/harfbuzz
-
-  The defaults already produce the OpenCV subset: output '.', features
-  HB_HAS_RASTER, and it also copies README.md + COPYING. Override only if needed:
-    -o DIR              output root (default '.')
-    -f FLAGS            comma-separated HB_HAS_* (default HB_HAS_RASTER)
-    -a FILES            extra files (default README.md,COPYING)
-    --list-flags        print available HB_HAS_* flags and exit
-
--a paths are relative to the harfbuzz repo root (parent of src/):
-  -a README.md            -> copied to   <out>/README.md
-  -a COPYING              -> copied to   <out>/COPYING
-  -a src/hb-raster.h      -> copied to   <out>/src/hb-raster.h

- * OpenCV-specific HarfBuzz configuration override.  GENERATED by hb_extract.py.
- *
- * HarfBuzz is built with HB_TINY (see 3rdparty/harfbuzz/CMakeLists.txt) for the
- * smallest possible footprint. HB_TINY pulls in HB_LEAN + HB_MINI, which would
- * disable two features that OpenCV's text engine relies on. We restore them
- * here.
- *
- * This file is included by hb-config.hh via HB_CONFIG_OVERRIDE_H, i.e. AFTER
- * HB_TINY/HB_LEAN/HB_MINI have expanded their macros (so the #undef below takes
- * effect) but BEFORE the "closure of options" derives dependent macros (e.g.
- * HB_NO_VAR_COMPOSITES from HB_NO_VAR). That ordering is what makes a plain
- * #undef sufficient.
- *
- *   HB_NO_MT  - keep thread-safety. hb_font_t instances live inside cv::FontFace
- *               objects, NOT in the thread_local FontRenderEngine, so a single
- *               FontFace (and its hb_font_t) can be shared across threads; its
- *               reference counting must stay atomic.
- *
- *   HB_NO_VAR - keep variable-font support: the 'wght' axis used for synthetic
- *               weights and named-instance/axis queries (hb_font_set_variations,
- *               hb_ot_var_*). Variable fonts are a primary reason OpenCV adopted
- *               HarfBuzz, so this must remain enabled.
