-# 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.

 A description of the currently available protocols follows.

-@section amqp
-
-Advanced Message Queueing Protocol (AMQP) version 0-9-1 is a broker based
-publish-subscribe communication protocol.
-
-FFmpeg must be compiled with --enable-librabbitmq to support AMQP. A separate
-AMQP broker must also be run. An example open-source AMQP broker is RabbitMQ.
-
-After starting the broker, an FFmpeg client may stream data to the broker using
-the command:
-
-@example
-ffmpeg -re -i input -f mpegts amqp://[[user]:[password]@@]hostname[:port][/vhost]
-@end example
-
-Where hostname and port (default is 5672) is the address of the broker. The
-client may also set a user/password for authentication. The default for both
-fields is "guest". Name of virtual host on broker can be set with vhost. The
-default value is "/".
-
-Muliple subscribers may stream from the broker using the command:
-@example
-ffplay amqp://[[user]:[password]@@]hostname[:port][/vhost]
-@end example
-
-In RabbitMQ all data published to the broker flows through a specific exchange,
-and each subscribing client has an assigned queue/buffer. When a packet arrives
-at an exchange, it may be copied to a client's queue depending on the exchange
-and routing_key fields.
-
-The following options are supported:
-
-@table @option
-
-@item exchange
-Sets the exchange to use on the broker. RabbitMQ has several predefined
-exchanges: "amq.direct" is the default exchange, where the publisher and
-subscriber must have a matching routing_key; "amq.fanout" is the same as a
-broadcast operation (i.e. the data is forwarded to all queues on the fanout
-exchange independent of the routing_key); and "amq.topic" is similar to
-"amq.direct", but allows for more complex pattern matching (refer to the RabbitMQ
-documentation).
-
-@item routing_key
-Sets the routing key. The default value is "amqp". The routing key is used on
-the "amq.direct" and "amq.topic" exchanges to decide whether packets are written
-to the queue of a subscriber.
-
-@item pkt_size
-Maximum size of each packet sent/received to the broker. Default is 131072.
-Minimum is 4096 and max is any large value (representable by an int). When
-receiving packets, this sets an internal buffer size in FFmpeg. It should be
-equal to or greater than the size of the published packets to the broker. Otherwise
-the received message may be truncated causing decoding errors.
-
-@item connection_timeout
-The timeout in seconds during the initial connection to the broker. The
-default value is rw_timeout, or 5 seconds if rw_timeout is not set.
-
-@item delivery_mode @var{mode}
-Sets the delivery mode of each message sent to broker.
-The following values are accepted:
-@table @samp
-@item persistent
-Delivery mode set to "persistent" (2). This is the default value.
-Messages may be written to the broker's disk depending on its setup.
-
-@item non-persistent

-The basis transforms used for FFT and various other derived functions are based
-on the following unrollings.
-The functions can be easily adapted to double precision floats as well.
-
-# Parity permutation
-The basis transforms described here all use the following permutation:
-
-``` C
-void ff_tx_gen_split_radix_parity_revtab(int *revtab, int len, int inv,
-                                         int basis, int dual_stride);
-```
-Parity means even and odd complex numbers will be split, e.g. the even
-coefficients will come first, after which the odd coefficients will be
-placed. For example, a 4-point transform's coefficients after reordering:
-`z[0].re, z[0].im, z[2].re, z[2].im, z[1].re, z[1].im, z[3].re, z[3].im`
-
-The basis argument is the length of the largest non-composite transform
-supported, and also implies that the basis/2 transform is supported as well,
-as the split-radix algorithm requires it to be.
-
-The dual_stride argument indicates that both the basis, as well as the
-basis/2 transforms support doing two transforms at once, and the coefficients
-will be interleaved between each pair in a split-radix like so (stride == 2):
-`tx1[0], tx1[2], tx2[0], tx2[2], tx1[1], tx1[3], tx2[1], tx2[3]`
-A non-zero number switches this on, with the value indicating the stride
-(how many values of 1 transform to put first before switching to the other).
-Must be a power of two or 0. Must be less than the basis.
-Value will be clipped to the transform size, so for a basis of 16 and a
-dual_stride of 8, dual 8-point transforms will be laid out as if dual_stride
-was set to 4.
-Usually you'll set this to half the complex numbers that fit in a single
-register or 0. This allows to reuse SSE functions as dual-transform
-functions in AVX mode.
-If length is smaller than basis/2 this function will not do anything.
-
-# 4-point FFT transform
-The only permutation this transform needs is to swap the `z[1]` and `z[2]`
-elements when performing an inverse transform, which in the assembly code is
-hardcoded with the function itself being templated and duplicated for each
-direction.

-The macros used are identical to those in the generic C version, only with all
-variable declarations exported to the function body.
-An important point here is that the high frequency registers (m2 and m3) have
-their high and low halves swapped in the output. This is intentional, as the
-inputs must also have the same layout, and therefore, the input swapping is only
-performed once for the bottom-most basis transform, with all subsequent combinations
-using the already swapped halves.
-
-Also note that this function requires a special iteration way, due to coefficients
-beginning to overlap, particularly `[o1]` with `[0]` after the second iteration.
-To iterate further, set `z = &z[16]` via `z += 8` for the second iteration. After
-the 4th iteration, the layout resets, so repeat the same.
