The check if a native layout can be created from the sources was incomplete and casued a crash with custom layouts if the layout contained a native channel multiple times, as in this example command line: ffmpeg -lavfi "sine[a0];sine,pan=FL+FL[a1];[a0][a1]amerge[aout]" -map "[aout]" -t 1 -f framecrc - Signed-off-by: Marton Balint <cus@passwd.hu> (cherry picked from commit e8b10a9b09)
avformat/os_support: Include stdint.h for int64_t

-@anchor{General Assembly}
-@chapter General Assembly
-
-The ensemble of active members is called the General Assembly (GA).
-
-The General Assembly is sovereign and legitimate for all its decisions regarding the FFmpeg project.
-
-The General Assembly is made up of active contributors.
-
-Contributors are considered "active contributors" if they have authored more than 20 patches in the last 36 months in the main FFmpeg repository, or if they have been voted in by the GA.
-
-The list of active contributors is updated twice each year, on 1st January and 1st July, 0:00 UTC.
-
-Additional members are added to the General Assembly through a vote after proposal by a member of the General Assembly. They are part of the GA for two years, after which they need a confirmation by the GA.
-
-A script to generate the current members of the general assembly (minus members voted in) can be found in `tools/general_assembly.pl`.
-

-@chapter Technical Committee
-
-The Technical Committee (TC) is here to arbitrate and make decisions when technical conflicts occur in the project. They will consider the merits of all the positions, judge them and make a decision.
-
-The TC resolves technical conflicts but is not a technical steering committee.
-
-Decisions by the TC are binding for all the contributors.
-
-Decisions made by the TC can be re-opened after 1 year or by a majority vote of the General Assembly, requested by one of the member of the GA.
-
-The TC is elected by the General Assembly for a duration of 1 year, and is composed of 5 members. Members can be re-elected if they wish. A majority vote in the General Assembly can trigger a new election of the TC.
-
-The members of the TC can be elected from outside of the GA. Candidates for election can either be suggested or self-nominated.
-
-The conflict resolution process is detailed in the resolution process document.

-
-The Technical Committee (TC) is here to arbitrate and make decisions when technical conflicts occur in the project.
-
-The TC main role is to resolve technical conflicts. It is therefore not a technical steering committee, but it is understood that some decisions might impact the future of the project.
-
-@subsection Seizing
-
-The TC can take possession of any technical matter that it sees fit.
-
-To involve the TC in a matter, email tc@ or CC them on an ongoing discussion.
-
-As members of TC are developers, they also can email tc@ to raise an issue.
-@subsection Announcement
-
-The TC, once seized, must announce itself on the main mailing list, with a [TC] tag.
-
-The TC has 2 modes of operation: a RFC one and an internal one.
-
-If the TC thinks it needs the input from the larger community, the TC can call for a RFC. Else, it can decide by itself.
-
-The decision to use a RFC process or an internal discussion is a discretionary decision of the TC.
-
-The TC can also reject a seizure for a few reasons such as: the matter was not discussed enough previously; it lacks expertise to reach a beneficial decision on the matter; or the matter is too trivial.
-@subsection RFC call
-
-In the RFC mode, one person from the TC posts on the mailing list the technical question and will request input from the community.
-
-The mail will have the following specification:
-
-    a precise title
-    a specific tag [TC RFC]
-    a top-level email
-    contain a precise question that does not exceed 100 words and that is answerable by developers
-    may have an extra description, or a link to a previous discussion, if deemed necessary,
-    contain a precise end date for the answers.
-
-The answers from the community must be on the main mailing list and must have the following specification:
-
-    keep the tag and the title unchanged
-    limited to 400 words
-    a first-level, answering directly to the main email
-    answering to the question.
-
-Further replies to answers are permitted, as long as they conform to the community standards of politeness, they are limited to 100 words, and are not nested more than once. (max-depth=2)
-
-After the end-date, mails on the thread will be ignored.
-
-Violations of those rules will be escalated through the Community Committee.
-
-After all the emails are in, the TC has 96 hours to give its final decision. Exceptionally, the TC can request an extra delay, that will be notified on the mailing list.
-@subsection Within TC
-
-In the internal case, the TC has 96 hours to give its final decision. Exceptionally, the TC can request an extra delay.
-@subsection Decisions
-
-The decisions from the TC will be sent on the mailing list, with the [TC] tag.
-
-Internally, the TC should take decisions with a majority, or using ranked-choice voting.
-
-Each TC member must vote on such decision according to what is, in their view, best for the project.
-
-If a TC member feels they are affected by a conflict of interest with regards to the case, they should announce it and recuse themselves from the TC
-discussion and vote.
-
-A conflict of interest is presumed to occur when a TC member has a personal interest (e.g. financial) in a specific outcome of the case.
-
-The decision from the TC should be published with a summary of the reasons that lead to this decision.
-
-The decisions from the TC are final, until the matters are reopened after no less than one year.
-
-@anchor{Community Committee}
-@chapter Community Committee
-
-The Community Committee (CC) is here to arbitrage and make decisions when inter-personal conflicts occur in the project. It will decide quickly and take actions, for the sake of the project.
-
-The CC can remove privileges of offending members, including removal of commit access and temporary ban from the community.
-
-Decisions made by the CC can be re-opened after 1 year or by a majority vote of the General Assembly. Indefinite bans from the community must be confirmed by the General Assembly, in a majority vote.
-
-The CC is elected by the General Assembly for a duration of 1 year, and is composed of 5 members. Members can be re-elected if they wish. A majority vote in the General Assembly can trigger a new election of the CC.

-@anchor{Code of Conduct}
-@chapter Code of Conduct
-
-Be friendly and respectful towards others and third parties.
-Treat others the way you yourself want to be treated.
-
-Be considerate. Not everyone shares the same viewpoint and priorities as you do.
-Different opinions and interpretations help the project.
-Looking at issues from a different perspective assists development.
-
-Do not assume malice for things that can be attributed to incompetence. Even if
-it is malice, it's rarely good to start with that as initial assumption.
-
-Stay friendly even if someone acts contrarily. Everyone has a bad day
-once in a while.
-If you yourself have a bad day or are angry then try to take a break and reply
-once you are calm and without anger if you have to.
-
-Try to help other team members and cooperate if you can.
-
-The goal of software development is to create technical excellence, not for any
-individual to be better and "win" against the others. Large software projects
-are only possible and successful through teamwork.
-
-If someone struggles do not put them down. Give them a helping hand
-instead and point them in the right direction.
-
-Finally, keep in mind the immortal words of Bill and Ted,
-"Be excellent to each other."

-can also be demuxed given the menu's coordinates (at best effort).
-
-Block devices (DVD drives), ISO files, and directory structures are accepted.
-Activate with @code{-f dvdvideo} in front of one of these inputs.
-
-This demuxer does NOT have decryption code of any kind. You are on your own
-working with encrypted DVDs, and should not expect support on the matter.
-
-Underlying playback is handled by libdvdnav, and structure parsing by libdvdread.
-FFmpeg must be built with GPL library support available as well as the
-configure switches @code{--enable-libdvdnav} and @code{--enable-libdvdread}.
-
-You will need to provide either the desired "title number" or exact PGC/PG coordinates.
-Many open-source DVD players and tools can aid in providing this information.
-If not specified, the demuxer will default to title 1 which works for many discs.
-However, due to the flexibility of the format, it is recommended to check manually.
-There are many discs that are authored strangely or with invalid headers.
-
-If the input is a real DVD drive, please note that there are some drives which may
-silently fail on reading bad sectors from the disc, returning random bits instead
-which is effectively corrupt data. This is especially prominent on aging or rotting discs.
-A second pass and integrity checks would be needed to detect the corruption.
-This is not an FFmpeg issue.
-
-@subsection Background
-
-DVD-Video is not a directly accessible, linear container format in the
-traditional sense. Instead, it allows for complex and programmatic playback of
-carefully muxed MPEG-PS streams that are stored in headerless VOB files.
-To the end-user, these streams are known simply as "titles", but the actual
-logical playback sequence is defined by one or more "PGCs", or Program Group Chains,
-within the title. The PGC is in turn comprised of multiple "PGs", or Programs",
-which are the actual video segments (and for a typical video feature, sequentially
-ordered). The PGC structure, along with stream layout and metadata, are stored in
-IFO files that need to be parsed. PGCs can be thought of as playlists in easier terms.
-
-An actual DVD player relies on user GUI interaction via menus and an internal VM
-to drive the direction of demuxing. Generally, the user would either navigate (via menus)
-or automatically be redirected to the PGC of their choice. During this process and
-the subsequent playback, the DVD player's internal VM also maintains a state and
-executes instructions that can create jumps to different sectors during playback.
-This is why libdvdnav is involved, as a linear read of the MPEG-PS blobs on the
-disc (VOBs) is not enough to produce the right sequence in many cases.
-
-There are many other DVD structures (a long subject) that will not be discussed here.
-NAV packets, in particular, are handled by this demuxer to build accurate timing
-but not emitted as a stream. For a good high-level understanding, refer to:
-@url{https://code.videolan.org/videolan/libdvdnav/-/blob/master/doc/dvd_structures}

+# FFmpeg project
+
+## Organisation
+
+The FFmpeg project is organized through a community working on global consensus.
+
+Decisions are taken by the ensemble of active members, through voting and
+are aided by two committees.
+
+## General Assembly
+
+The ensemble of active members is called the General Assembly (GA).
+
+The General Assembly is sovereign and legitimate for all its decisions
+regarding the FFmpeg project.
+
+The General Assembly is made up of active contributors.
+
+Contributors are considered "active contributors" if they have pushed more
+than 20 patches in the last 36 months in the main FFmpeg repository, or
+if they have been voted in by the GA.
+
+Additional members are added to the General Assembly through a vote after
+proposal by a member of the General Assembly.
+They are part of the GA for two years, after which they need a confirmation by
+the GA.
+
+## Voting
+
+Voting is done using a ranked voting system, currently running on https://vote.ffmpeg.org/ .
+
+Majority vote means more than 50% of the expressed ballots.
+
+## Technical Committee
+
+The Technical Committee (TC) is here to arbitrate and make decisions when
+technical conflicts occur in the project.
+They will consider the merits of all the positions, judge them and make a
+decision.
+
+The TC resolves technical conflicts but is not a technical steering committee.
+
+Decisions by the TC are binding for all the contributors.
+
+Decisions made by the TC can be re-opened after 1 year or by a majority vote
+of the General Assembly, requested by one of the member of the GA.
+
+The TC is elected by the General Assembly for a duration of 1 year, and
+is composed of 5 members.
+Members can be re-elected if they wish. A majority vote in the General Assembly
+can trigger a new election of the TC.
+
+The members of the TC can be elected from outside of the GA.
+Candidates for election can either be suggested or self-nominated.
+
+The conflict resolution process is detailed in the [resolution process](resolution_process.md) document.
+
+## Community committee
+
+The Community Committee (CC) is here to arbitrage and make decisions when
+inter-personal conflicts occur in the project. It will decide quickly and
+take actions, for the sake of the project.
+
+The CC can remove privileges of offending members, including removal of
+commit access and temporary ban from the community.
+
+Decisions made by the CC can be re-opened after 1 year or by a majority vote
+of the General Assembly. Indefinite bans from the community must be confirmed
+by the General Assembly, in a majority vote.
+
+The CC is elected by the General Assembly for a duration of 1 year, and is
+composed of 5 members.
+Members can be re-elected if they wish. A majority vote in the General Assembly
+can trigger a new election of the CC.
+
+The members of the CC can be elected from outside of the GA.
+Candidates for election can either be suggested or self-nominated.
+
+The CC is governed by and responsible for enforcing the Code of Conduct.

+# Technical Committee
+
+_This document only makes sense with the rules from [the community document](community)_.
+
+The Technical Committee (**TC**) is here to arbitrate and make decisions when
+technical conflicts occur in the project.
+
+The TC main role is to resolve technical conflicts.
+It is therefore not a technical steering committee, but it is understood that
+some decisions might impact the future of the project.
+
+# Process
+
+## Seizing
+
+The TC can take possession of any technical matter that it sees fit.
+
+To involve the TC in a matter, email tc@ or CC them on an ongoing discussion.
+
+As members of TC are developers, they also can email tc@ to raise an issue.
+
+## Announcement
+
+The TC, once seized, must announce itself on the main mailing list, with a _[TC]_ tag.
+
+The TC has 2 modes of operation: a RFC one and an internal one.
+
+If the TC thinks it needs the input from the larger community, the TC can call
+for a RFC. Else, it can decide by itself.
+
+If the disagreement involves a member of the TC, that member should recuse
+themselves from the decision.
+
+The decision to use a RFC process or an internal discussion is a discretionary
+decision of the TC.
+
+The TC can also reject a seizure for a few reasons such as:
+the matter was not discussed enough previously; it lacks expertise to reach a
+beneficial decision on the matter; or the matter is too trivial.
+
+### RFC call
+
+In the RFC mode, one person from the TC posts on the mailing list the
+technical question and will request input from the community.
+
+The mail will have the following specification:
+* a precise title
+* a specific tag [TC RFC]
+* a top-level email
+* contain a precise question that does not exceed 100 words and that is answerable by developers
+* may have an extra description, or a link to a previous discussion, if deemed necessary,
+* contain a precise end date for the answers.
+
+The answers from the community must be on the main mailing list and must have
+the following specification:
+* keep the tag and the title unchanged
+* limited to 400 words
+* a first-level, answering directly to the main email
+* answering to the question.
+
+Further replies to answers are permitted, as long as they conform to the
+community standards of politeness, they are limited to 100 words, and are not
+nested more than once. (max-depth=2)
+
+After the end-date, mails on the thread will be ignored.
+
+Violations of those rules will be escalated through the Community Committee.
+
+After all the emails are in, the TC has 96 hours to give its final decision.
+Exceptionally, the TC can request an extra delay, that will be notified on the
+mailing list.
+
+### Within TC
+
+In the internal case, the TC has 96 hours to give its final decision.
+Exceptionally, the TC can request an extra delay.
+
+
+## Decisions
+
+The decisions from the TC will be sent on the mailing list, with the _[TC]_ tag.
+
+Internally, the TC should take decisions with a majority, or using
+ranked-choice voting.
+
+The decision from the TC should be published with a summary of the reasons that
+lead to this decision.
+
+The decisions from the TC are final, until the matters are reopened after
+no less than one year.

-This text is concerned with the development @emph{of} FFmpeg itself. Information
-on using the FFmpeg libraries in other programs can be found elsewhere, e.g. in:
-@itemize @bullet
-@item
-the installed header files
-@item

+This document is mostly useful for internal FFmpeg developers.
+External developers who need to use the API in their application should
+refer to the API doxygen documentation in the public headers, and
+check the examples in @file{doc/examples} and in the source code to
+see how the public API is employed.
+
+You can use the FFmpeg libraries in your commercial program, but you
+are encouraged to @emph{publish any patch you make}. In this case the
+best way to proceed is to send your patches to the ffmpeg-devel

@chapter Coding Rules

-@section Language
-
-FFmpeg is mainly programmed in the ISO C11 language, except for the public
-headers which must stay C99 compatible.
-
-Compiler-specific extensions may be used with good reason, but must not be
-depended on, i.e. the code must still compile and work with compilers lacking
-the extension.
-
-The following C99 features must not be used anywhere in the codebase:
-@itemize @bullet
-@item
-variable-length arrays;
-
-@item
-complex numbers;
-@end itemize
-
-@subsection SIMD/DSP
-@anchor{SIMD/DSP}
-
-As modern compilers are unable to generate efficient SIMD or other
-performance-critical DSP code from plain C, handwritten assembly is used.
-Usually such code is isolated in a separate function. Then the standard approach
-is writing multiple versions of this function – a plain C one that works
-everywhere and may also be useful for debugging, and potentially multiple
-architecture-specific optimized implementations. Initialization code then
-chooses the best available version at runtime and loads it into a function
-pointer; the function in question is then always called through this pointer.
-
-The specific syntax used for writing assembly is:
-@itemize @bullet
-@item
-NASM on x86;
-
-@item
-GAS on ARM and RISC-V.
-@end itemize
-
-A unit testing framework for assembly called @code{checkasm} lives under
-@file{tests/checkasm}. All new assembly should come with @code{checkasm} tests;
-adding tests for existing assembly that lacks them is also strongly encouraged.
-
-@subsection Other languages
-
-Other languages than C may be used in special cases:
-@itemize @bullet
-@item
-Compiler intrinsics or inline assembly when the code in question cannot be
-written in the standard way described in the @ref{SIMD/DSP} section. This
-typically applies to code that needs to be inlined.
-
-@item
-Objective-C where required for interacting with macOS-specific interfaces.

-Struct, union, enum, and typedeffed type names must use CamelCase. All structs
-and unions should be typedeffed to the same name as the struct/union tag, e.g.

-The @code{ff_} prefix must be used for variables and functions visible outside

-@section Library public interfaces
-Every library in FFmpeg provides a set of public APIs in its installed headers,
-which are those listed in the variable @code{HEADERS} in that library's
-@file{Makefile}. All identifiers defined in those headers (except for those
-explicitly documented otherwise), and corresponding symbols exported from
-compiled shared or static libraries are considered public interfaces and must
-comply with the API and ABI compatibility rules described in this section.
-
-Public APIs must be backward compatible within a given major version. I.e. any
-valid user code that compiles and works with a given library version must still
-compile and work with any later version, as long as the major version number is
-unchanged. "Valid user code" here means code that is calling our APIs in a
-documented and/or intended manner and is not relying on any undefined behavior.
-Incrementing the major version may break backward compatibility, but only to the
-extent described in @ref{Major version bumps}.
-
-We also guarantee backward ABI compatibility for shared and static libraries.
-I.e. it should be possible to replace a shared or static build of our library
-with a build of any later version (re-linking the user binary in the static
-case) without breaking any valid user binaries, as long as the major version
-number remains unchanged.
-
-@subsection Adding new interfaces
-Any new public identifiers in installed headers are considered new API - this
-includes new functions, structs, macros, enum values, typedefs, new fields in
-existing structs, new installed headers, etc. Consider the following
-guidelines when adding new APIs.
-
-@subsubheading Motivation
-While new APIs can be added relatively easily, changing or removing them is much
-harder due to abovementioned compatibility requirements. You should then
-consider carefully whether the functionality you are adding really needs to be
-exposed to our callers as new public API.
-
-Your new API should have at least one well-established use case outside of the
-library that cannot be easily achieved with existing APIs. Every library in
-FFmpeg also has a defined scope - your new API must fit within it.
-
-@subsubheading Replacing existing APIs
-If your new API is replacing an existing one, it should be strictly superior to
-it, so that the advantages of using the new API outweigh the cost to the
-callers of changing their code. After adding the new API you should then
-deprecate the old one and schedule it for removal, as described in
-@ref{Removing interfaces}.
-
-If you deem an existing API deficient and want to fix it, the preferred approach
-in most cases is to add a differently-named replacement and deprecate the
-existing API rather than modify it. It is important to make the changes visible
-to our callers (e.g. through compile- or run-time deprecation warnings) and make
-it clear how to transition to the new API (e.g. in the Doxygen documentation or
-on the wiki).
-
-@subsubheading API design
-The FFmpeg libraries are used by a variety of callers to perform a wide range of
-multimedia-related processing tasks. You should therefore - within reason - try
-to design your new API for the broadest feasible set of use cases and avoid
-unnecessarily limiting it to a specific type of callers (e.g. just media
-playback or just transcoding).
-
-@subsubheading Consistency
-Check whether similar APIs already exist in FFmpeg. If they do, try to model
-your new addition on them to achieve better overall consistency.
-
-The naming of your new identifiers should follow the @ref{Naming conventions}
-and be aligned with other similar APIs, if applicable.
-
-@subsubheading Extensibility
-You should also consider how your API might be extended in the future in a
-backward-compatible way. If you are adding a new struct @code{AVFoo}, the
-standard approach is requiring the caller to always allocate it through a
-constructor function, typically named @code{av_foo_alloc()}. This way new fields
-may be added to the end of the struct without breaking ABI compatibility.
-Typically you will also want a destructor - @code{av_foo_free(AVFoo**)} that
-frees the indirectly supplied object (and its contents, if applicable) and
-writes @code{NULL} to the supplied pointer, thus eliminating the potential
-dangling pointer in the caller's memory.
-
-If you are adding new functions, consider whether it might be desirable to tweak
-their behavior in the future - you may want to add a flags argument, even though
-it would be unused initially.
-
-@subsubheading Documentation
-All new APIs must be documented as Doxygen-formatted comments above the
-identifiers you add to the public headers. You should also briefly mention the
-change in @file{doc/APIchanges}.
-
-@subsubheading Bump the version
-Backward-incompatible API or ABI changes require incrementing (bumping) the
-major version number, as described in @ref{Major version bumps}. Major
-bumps are significant events that happen on a schedule - so if your change
-strictly requires one you should add it under @code{#if} preprocessor guards that
-disable it until the next major bump happens.
-
-New APIs that can be added without breaking API or ABI compatibility require
-bumping the minor version number.
-
-Incrementing the third (micro) version component means a noteworthy binary
-compatible change (e.g. encoder bug fix that matters for the decoder). The third
-component always starts at 100 to distinguish FFmpeg from Libav.
-
-@anchor{Removing interfaces}
-@subsection Removing interfaces
-Due to abovementioned compatibility guarantees, removing APIs is an involved
-process that should only be undertaken with good reason. Typically a deficient,
-restrictive, or otherwise inadequate API is replaced by a superior one, though
-it does at times happen that we remove an API without any replacement (e.g. when
-the feature it provides is deemed not worth the maintenance effort, out of scope
-of the project, fundamentally flawed, etc.).
-
-The removal has two steps - first the API is deprecated and scheduled for
-removal, but remains present and functional. The second step is actually
-removing the API - this is described in @ref{Major version bumps}.
-
-To deprecate an API you should signal to our users that they should stop using
-it. E.g. if you intend to remove struct members or functions, you should mark
-them with @code{attribute_deprecated}. When this cannot be done, it may be
-possible to detect the use of the deprecated API at runtime and print a warning
-(though take care not to print it too often). You should also document the
-deprecation (and the replacement, if applicable) in the relevant Doxygen

-Finally, you should define a deprecation guard along the lines of
-@code{#define FF_API_<FOO> (LIBAVBAR_VERSION_MAJOR < XX)} (where XX is the major
-version in which the API will be removed) in @file{libavbar/version_major.h}
-(@file{version.h} in case of @code{libavutil}). Then wrap all uses of the
-deprecated API in @code{#if FF_API_<FOO> .... #endif}, so that the code will
-automatically get disabled once the major version reaches XX. You can also use
-@code{FF_DISABLE_DEPRECATION_WARNINGS} and @code{FF_ENABLE_DEPRECATION_WARNINGS}
-to suppress compiler deprecation warnings inside these guards. You should test
-that the code compiles and works with the guard macro evaluating to both true
-and false.

-Removing previously deprecated APIs.

+@chapter Code of conduct
+
+Be friendly and respectful towards others and third parties.
+Treat others the way you yourself want to be treated.
+
+Be considerate. Not everyone shares the same viewpoint and priorities as you do.
+Different opinions and interpretations help the project.
+Looking at issues from a different perspective assists development.
+
+Do not assume malice for things that can be attributed to incompetence. Even if
+it is malice, it's rarely good to start with that as initial assumption.
+
+Stay friendly even if someone acts contrarily. Everyone has a bad day
+once in a while.
+If you yourself have a bad day or are angry then try to take a break and reply
+once you are calm and without anger if you have to.
+
+Try to help other team members and cooperate if you can.
+
+The goal of software development is to create technical excellence, not for any
+individual to be better and "win" against the others. Large software projects
+are only possible and successful through teamwork.
+
+If someone struggles do not put them down. Give them a helping hand
+instead and point them in the right direction.

+Finally, keep in mind the immortal words of Bill and Ted,

+CONTEXT
+=======
+
+The FFmpeg project merges all the changes from the Libav project
+(https://libav.org) since the origin of the fork (around 2011).
+
+With the exceptions of some commits due to technical/political disagreements or
+issues, the changes are merged on a more or less regular schedule (daily for
+years thanks to Michael, but more sparse nowadays).
+
+WHY
+===
+
+The majority of the active developers believe the project needs to keep this
+policy for various reasons.
+
+The most important one is that we don't want our users to have to choose
+between two distributors of libraries of the exact same name in order to have a
+different set of features and bugfixes. By taking the responsibility of
+unifying the two codebases, we allow users to benefit from the changes from the
+two teams.
+
+Today, FFmpeg has a much larger user database (we are distributed by every
+major distribution), so we consider this mission a priority.
+
+A different approach to the merge could have been to pick the changes we are
+interested in and drop most of the cosmetics and other less important changes.
+Unfortunately, this makes the following picks much harder, especially since the
+Libav project is involved in various deep API changes. As a result, we decide
+to virtually take everything done there.
+
+Any Libav developer is of course welcome anytime to contribute directly to the
+FFmpeg tree. Of course, we fully understand and are forced to accept that very
+few Libav developers are interested in doing so, but we still want to recognize
+their work. This leads us to create merge commits for every single one from
+Libav. The original commit appears totally unchanged with full authorship in
+our history (and the conflict are solved in the merge one). That way, not a
+single thing from Libav will be lost in the future in case some reunification
+happens, or that project disappears one way or another.
+
+DOWNSIDES
+=========
+
+Of course, there are many downsides to this approach.
+
+- It causes a non negligible merge commits pollution. We make sure there are
+  not several level of merges entangled (we do a 1:1 merge/commit), but it's
+  still a non-linear history.
+
+- Many duplicated work. For instance, we added libavresample in our tree to
+  keep compatibility with Libav when our libswresample was already covering the
+  exact same purpose. The same thing happened for various elements such as the
+  ProRes support (but differences in features, bugs, licenses, ...). There are
+  many work to do to unify them, and any help is very much welcome.
+
+- So much manpower from both FFmpeg and Libav is lost because of this mess. We
+  know it, and we don't know how to fix it. It takes incredible time to do
+  these merges, so we have even less time to work on things we personally care
+  about. The bad vibes also do not help with keeping our developers motivated.
+
+- There is a growing technical risk factor with the merges due to the codebase
+  differing more and more.
+
+MERGE GUIDELINES
+================
+
+The following gives developer guidelines on how to proceed when merging Libav commits.
+
+Before starting, you can reduce the risk of errors on merge conflicts by using
+a different merge conflict style:
+
+    $ git config --global merge.conflictstyle diff3
+
+tools/libav-merge-next-commit is a script to help merging the next commit in
+the queue. It assumes a remote named libav. It has two modes: merge, and noop.
+The noop mode creates a merge with no change to the HEAD. You can pass a hash
+as extra argument to reference a justification (it is common that we already
+have the change done in FFmpeg).
+
+Also see tools/murge, you can copy and paste a 3 way conflict into its stdin
+and it will display colored diffs. Any arguments to murge (like ones to suppress
+whitespace differences) are passed into colordiff.
+
+TODO/FIXME/UNMERGED
+===================
+
+Stuff that didn't reach the codebase:
+-------------------------------------
+
+- HEVC DSP and x86 MC SIMD improvements from Libav (see https://ffmpeg.org/pipermail/ffmpeg-devel/2015-December/184777.html)
+  - 1f821750f hevcdsp: split the qpel functions by width instead of by the subpixel fraction
+  - 818bfe7f0 hevcdsp: split the epel functions by width
+  - 688417399 hevcdsp: split the pred functions by width
+  - a853388d2 hevc: change the stride of the MC buffer to be in bytes instead of elements
+  - 0cef06df0 checkasm: add HEVC MC tests
+  - e7078e842 hevcdsp: add x86 SIMD for MC
+  - 7993ec19a hevc: Add hevc_get_pixel_4/8/12/16/24/32/48/64
+- use av_cpu_max_align() instead of hardcoding alignment requirements (see https://ffmpeg.org/pipermail/ffmpeg-devel/2017-September/215834.html)
+  - f44ec22e0 lavc: use av_cpu_max_align() instead of hardcoding alignment requirements
+  - 4de220d2e frame: allow align=0 (meaning automatic) for av_frame_get_buffer()
+- Support recovery from an already present HLS playlist (see 16cb06bb30)
+- Remove all output devices (see 8e7e042d41, 8d3db95f20, 6ce13070bd, d46cd24986 and https://ffmpeg.org/pipermail/ffmpeg-devel/2017-September/216904.html)
+- avcodec/libaomenc: export the Sequence Header OBU as extradata (See a024c3ce9a)
+
+Collateral damage that needs work locally:
+------------------------------------------
+
+- Merge proresenc_anatoliy.c and proresenc_kostya.c
+- Fix MIPS AC3 downmix
+
+Extra changes needed to be aligned with Libav:
+----------------------------------------------
+
+- Switching our examples to the new encode/decode API (see 67d28f4a0f)
+- HEVC IDCT bit depth 12-bit support (Libav added 8 and 10 but doesn't have 12)
