-      in keys or values now has to be backslash-escaped
-    - in optional maps (-map ....?) with a metadata-matching stream specifier,
-      the value has to be separated from the question mark by a colon, i.e.
-      -map ....:m:<key>:<val>:? (otherwise it would be ambiguous whether the
-      question mark is a part of <val> or not)
-    - multiple stream types in a single specifier (e.g. :s:s:0) now cause an
-      error, as such a specifier makes no sense

-NOTICE for Package Maintainers
-------------------------------
-
- - It is recommended to build FFmpeg twice, first with minimal external dependencies so
-   that 3rd party packages, which depend on FFmpegs libavutil/libavfilter/libavcodec/libavformat
-   can then be built. And last build FFmpeg with full dependancies (which may in turn depend on
-   some of these 3rd party packages). This avoids circular dependencies during build.

-@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 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.
-
-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.
-
-The CC can be contacted at <cc@@ffmpeg>.
-
-@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."

-FFmpeg must be built with GPL library support available as well as the

-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.

 @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;
-
-@item
-mixed statements and declarations.
-@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.
-

-Objective-C where required for interacting with macOS-specific interfaces.

-@subheading Robustness
-The code must treat as untrusted any bytestream received from a caller or read
-from a file, network, etc. It must not misbehave when arbitrary data is sent to
-it - typically it should print an error message and return
-@code{AVERROR_INVALIDDATA} on encountering invalid input data.
-
-@subheading Memory allocation
-The code must use the @code{av_malloc()} family of functions from
-@file{libavutil/mem.h} to perform all memory allocation, except in special cases
-(e.g. when interacting with an external library that requires a specific
-allocator to be used).
-
-All allocations should be checked and @code{AVERROR(ENOMEM)} returned on
-failure. A common mistake is that error paths leak memory - make sure that does
-not happen.
-
-@subheading stdio

-@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 outweight 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} preprocesor 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
-documentation block.
-
-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.

-Set probing size, in bytes, for input duration estimation when it actually requires
-an additional probing for PTS at end of file (at present: MPEG-PS and MPEG-TS).
-It is aimed at users interested in better durations probing for itself, or indirectly
-because using the concat demuxer, for example.
-The typical use case is an MPEG-TS CBR with a high bitrate, high video buffering and
-ending cleaning with similar PTS for video and audio: in such a scenario, the large
-physical gap between the last video packet and the last audio packet makes it necessary
-to read many bytes in order to get the video stream duration.
-Another use case is where the default probing behaviour only reaches a single video frame which is
-not the last one of the stream due to frame reordering, so the duration is not accurate.
-Setting this option has a performance impact even for small files because the probing
-size is fixed.
-Default behaviour is a general purpose trade-off, largely adaptive, but the probing size
-will not be extended to get streams durations at all costs.
-Must be an integer not lesser than 1, or 0 for default behaviour.
