# 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 option allows for compression using compression ratio. The compression ratio for each
level could be specified. The compression ratio of a layer @code{l} species the what ratio of
total file size is contained in the first @code{l} layers.
Example usage:
@example
ffmpeg -i input.bmp -c:v jpeg2000 -layer_rates "100,10,1" output.j2k
@end example
This would compress the image to contain 3 layers, where the data contained in the
first layer would be compressed by 1000 times, compressed by 100 in the first two layers,
and shall contain all data while using all 3 layers.
