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 dependencies (which may in turn depend on
|
||||
some of these 3rd party packages). This avoids circular dependencies during build.

is seeking will return garbled output until a new PPS appears.

@chapter 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.
|
||||
|
||||
@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`.
|
||||
|
||||
@anchor{Voting}
|
||||
@chapter 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.

@anchor{Technical Committee}
|

@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 be contacted at <tc@@ffmpeg>.

|
||||
@section Resolution Process
|
||||
|
||||
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.
|
||||
|
||||
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."

HEVC (AKA ITU-T H.265 or ISO/IEC 23008-2) decoder.
|
||||
|
||||
The decoder supports MV-HEVC multiview streams with at most two views. Views to
|
||||
be output are selected by supplying a list of view IDs to the decoder (the
|
||||
@option{view_ids} option). This option may be set either statically before
|

decoder init, or from the @code{get_format()} callback - useful for the case
|
||||
when the view count or IDs change dynamically during decoding.
|
||||
|
||||
Only the base layer is decoded by default.
|
||||
|
||||
Note that if you are using the @code{ffmpeg} CLI tool, you should be using view

||||
@subsection Options
|

|
||||
@table @option
|

@item view_ids (MV-HEVC)
|
||||
Specify a list of view IDs that should be output. This option can also be set to
|

a single '-1', which will cause all views defined in the VPS to be decoded and
|
||||
output.
|
||||

@item view_ids_available (MV-HEVC)
|
||||
This option may be read by the caller to retrieve an array of view IDs available
|

in the active VPS. The array is empty for single-layer video.
|
||||
|
||||
The value of this option is guaranteed to be accurate when read from the
|
||||
@code{get_format()} callback. It may also be set at other times (e.g. after
|
||||
opening the decoder), but the value is informational only and may be incorrect
|
||||
(e.g. when the stream contains multiple distinct VPS NALUs).
|
||||
|
||||
@item view_pos_available (MV-HEVC)
|
||||
This option may be read by the caller to retrieve an array of view positions
|
||||
(left, right, or unspecified) available in the active VPS, as
|
||||
@code{AVStereo3DView} values. When the array is available, its elements apply to
|
||||
the corresponding elements of @option{view_ids_available}, i.e.
|

@code{view_pos_available[i]} contains the position of view with ID
|

@code{view_ids_available[i]}.

@item -ass_single_rect @var{boolean}
|
||||
ARIB STD-B24 specifies that some captions may be displayed at different

positions at a time (multi-rectangle subtitle).
|
||||
Since some players (e.g., old @dfn{mpv}) can't handle multiple ASS rectangles
|
||||
in a single AVSubtitle, or multiple ASS rectangles of indeterminate duration
|
||||
with the same start timestamp, this option can change the behavior so that
|
||||
all the texts are displayed in a single ASS rectangle.
|
||||
|
||||
The default is @var{false}.
|
||||
|
||||
If your player cannot handle AVSubtitles with multiple ASS rectangles properly,
|

set this option to @var{true} or define @env{ASS_SINGLE_RECT=1} to change
|

|
||||
|
||||
The default is @var{true}.
|

|
||||
@item -replace_msz_ascii @var{boolean}
|
||||
Specify whether to replace MSZ (Middle Size; half width) fullwidth
|
||||
alphanumerics with halfwidth alphanumerics.
|
||||
|
||||
The default is @var{true}.
|
||||
|

@item -replace_msz_japanese @var{boolean}
|

|
||||
|
||||
The default is @var{true}.
|
||||

This option works under FreeType or DirectWrite renderer
|
||||
with Adobe-Japan1 compliant fonts.

||||
Yu Gothic, Yu Mincho, and Meiryo.
|
||||
|
||||
The default is @var{true}.
|
||||
|
||||
@item -canvas_size @var{image_size}
|
||||
Specify the resolution of the canvas to render subtitles to; usually, this
|
||||
should be frame size of input video.
|
||||
This only applies when @code{-subtitle_type} is set to @var{bitmap}.
|
||||
|
||||
The libaribcaption decoder assumes input frame size for bitmap rendering as below:
|
||||
@enumerate
|
||||
@item
|
||||
PROFILE_A : 1440 x 1080 with SAR (PAR) 4:3
|
||||
@item
|
||||
PROFILE_C : 320 x 180 with SAR (PAR) 1:1
|
||||
@end enumerate
|
||||
|
||||
If actual frame size of input video does not match above assumption,
|
||||
the rendered captions may be distorted.
|
||||
To make the captions undistorted, add @code{-canvas_size} option to specify
|
||||
actual input video size.
|
||||
|
||||
Note that the @code{-canvas_size} option is not required for video with
|
||||
different size but same aspect ratio.
|
||||
In such cases, the caption will be stretched or shrunk to actual video size
|
||||
if @code{-canvas_size} option is not specified.
|
||||
If @code{-canvas_size} option is specified with different size,
|
||||
the caption will be stretched or shrunk as specified size with calculated SAR.

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:

|
||||
@table @option
|
||||
|
||||
@item title @var{int}
|
||||
The title number to play. Must be set if @option{pgc} and @option{pg} are not set.
|
||||
Not applicable to menus.
|
||||
Default is 0 (auto), which currently only selects the first available title (title 1)
|
||||
and notifies the user about the implications.
|
||||
|
||||
@item chapter_start @var{int}
|
||||
The chapter, or PTT (part-of-title), number to start at. Not applicable to menus.

||||
Default is 1.
|
||||
|
||||
@item chapter_end @var{int}
|
||||
The chapter, or PTT (part-of-title), number to end at. Not applicable to menus.
|
||||
Default is 0, which is a special value to signal end at the last possible chapter.
|
||||
|
||||
@item angle @var{int}
|
||||
The video angle number, referring to what is essentially an additional
|
||||
video stream that is composed from alternate frames interleaved in the VOBs.
|
||||
Not applicable to menus.
|
||||
Default is 1.
|
||||
|
||||
@item region @var{int}
|
||||
The region code to use for playback. Some discs may use this to default playback
|
||||
at a particular angle in different regions. This option will not affect the region code
|
||||
of a real DVD drive, if used as an input. Not applicable to menus.
|
||||
Default is 0, "world".
|
||||
|
||||
@item menu @var{bool}
|
||||
Demux menu assets instead of navigating a title. Requires exact coordinates
|
||||
of the menu (@option{menu_lu}, @option{menu_vts}, @option{pgc}, @option{pg}).
|
||||
Default is false.
|
||||
|
||||
@item menu_lu @var{int}
|
||||
The menu language to demux. In DVD, menus are grouped by language.
|
||||
Default is 1, the first language unit.
|
||||
|
||||
@item menu_vts @var{int}
|
||||
The VTS where the menu lives, or 0 if it is a VMG menu (root-level).
|
||||
Default is 1, menu of the first VTS.
|
||||
|
||||
@item pgc @var{int}
|
||||
The entry PGC to start playback, in conjunction with @option{pg}.
|
||||
Alternative to setting @option{title}.
|
||||
Chapter markers are not supported at this time.
|
||||
Must be explicitly set for menus.
|
||||
Default is 0, automatically resolve from value of @option{title}.
|
||||
|
||||
@item pg @var{int}
|
||||
The entry PG to start playback, in conjunction with @option{pgc}.
|
||||
Alternative to setting @option{title}.
|
||||
Chapter markers are not supported at this time.
|
||||
Default is 1, the first PG of the PGC.
|
||||
|
||||
@item preindex @var{bool}
|
||||
Enable this to have accurate chapter (PTT) markers and duration measurement,
|
||||
which requires a slow second pass read in order to index the chapter marker
|
||||
timestamps from NAV packets. This is non-ideal extra work for real optical drives.
|
||||
It is recommended and faster to use this option with a backup of the DVD structure
|
||||
stored on a hard drive. Not compatible with @option{pgc} and @option{pg}.
|
||||
Default is 0, false.
|
||||
|
||||
@item trim @var{bool}
|
||||
Skip padding cells (i.e. cells shorter than 1 second) from the beginning.
|
||||
There exist many discs with filler segments at the beginning of the PGC,
|
||||
often with junk data intended for controlling a real DVD player's
|
||||
buffering speed and with no other material data value.
|
||||
Not applicable to menus.

Demuxer for MacCaption MCC files, it supports MCC versions 1.0 and 2.0.
|
||||
MCC files store VANC data, which can include closed captions (EIA-608 and CEA-708), ancillary time code, pan-scan data, etc.
|
||||
By default, for backward compatibility, the MCC demuxer extracts just the EIA-608 and CEA-708 closed captions and returns a @code{EIA_608} stream, ignoring all other VANC data.
|

You can change it to return all VANC data in a @code{SMPTE_436M_ANC} data stream by setting @option{-eia608_extract 0}

# 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.
|
||||
|
||||
A script to generate the current members of the general assembly (minus members
|
||||
voted in) can be found in `tools/general_assembly.pl`.
|
||||
|
||||
## 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.

@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:

@section Code behaviour
|
||||
|
||||
@subheading Correctness
|
||||
The code must be valid. It must not crash, abort, access invalid pointers, leak
|
||||
memory, cause data races or signed integer overflow, or otherwise cause
|
||||
undefined behaviour. Error codes should be checked and, when applicable,
|
||||
forwarded to the caller.
|
||||
|
||||
@subheading Thread- and library-safety
|
||||
Our libraries may be called by multiple independent callers in the same process.
|
||||
These calls may happen from any number of threads and the different call sites
|
||||
may not be aware of each other - e.g. a user program may be calling our
|
||||
libraries directly, and use one or more libraries that also call our libraries.
|
||||
The code must behave correctly under such conditions.
|
||||
|
||||
@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
|
||||
Our libraries must not access the stdio streams stdin/stdout/stderr directly

logging, use @code{av_log()}.

@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
|
||||
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.

|

|

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.

"Be excellent to each other."

|

Set probing size, in bytes, for input duration estimation when it actually requires

|

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.

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)

@code{AV_DEV_TO_APP_CREATE_WINDOW_BUFFER} - create OpenGL context on current thread.
|
||||
@code{AV_DEV_TO_APP_PREPARE_WINDOW_BUFFER} - make OpenGL context current.

@code{AV_DEV_TO_APP_DISPLAY_WINDOW_BUFFER} - swap buffers.
|
||||
@code{AV_DEV_TO_APP_DESTROY_WINDOW_BUFFER} - destroy OpenGL context.

New swscale design to change everything (tm)
|
||||
============================================
|
||||
|
||||
SwsGraph
|
||||
--------
|
||||
|
||||
The entry point to the new architecture, SwsGraph is what coordinates
|
||||
multiple "passes". These can include cascaded scaling passes, error diffusion
|
||||
dithering, and so on. Or we could have separate passes for the vertical and
|
||||
horizontal scaling. In between each SwsPass lies a fully allocated image buffer.
|
||||
Graph passes may have different levels of threading, e.g. we can have a single
|
||||
threaded error diffusion pass following a multi-threaded scaling pass.
|
||||
|
||||
SwsGraph is internally recreated whenever the image format, dimensions or
|
||||
settings change in any way. sws_scale_frame() is itself just a light-weight
|
||||
wrapper that runs ff_sws_graph_create() whenever the format changes, splits
|
||||
interlaced images into separate fields, and calls ff_sws_graph_run() on each.
|
||||
|
||||
From the point of view of SwsGraph itself, all inputs are progressive.
|
||||
|
||||
SwsOp / SwsOpList
|
||||
-----------------
|
||||
|
||||
This is the newly introduced abstraction layer between the high-level format
|
||||
handling logic and the low-level backing implementation. Each SwsOp is designed
|
||||
to be as small and atomic as possible, with the possible exception of the
|
||||
read / write operations due to their numerous variants.
|
||||
|
||||
The basic idea is to split logic between three major components:
|
||||
|
||||
1. The high-level format "business logic", which generates in a very
|
||||
naive way a sequence of operations guaranteed to get you from point A
|
||||
to point B. This logic is written with correctness in mind only, and
|
||||
ignoring any performance concerns or low-level implementation decisions.
|
||||
Semantically, everything is always decoded from the input format to
|
||||
normalized (real valued) RGB, and then encoded back to output format.
|
||||
|
||||
This code lives in libswscale/format.c
|
||||
|
||||
2. The optimizer. This is where the "magic" happens, so to speak. The
|
||||
optimizer's job is to take the abstract sequence of operations
|
||||
produced by the high-level format analysis code and incrementally
|
||||
optimize it. Each optimization step is designed to be minute and provably
|
||||
lossless, or otherwise guarded behind the BITEXACT flag. This ensures that
|
||||
the resulting output is always identical, no matter how many layers of
|
||||
optimization we add.
|
||||
|
||||
This code lives in libswscale/ops.c
|
||||
|
||||
3. The compiler. Once we have a sequence of operations as output by the
|
||||
optimizer, we "compile" this down to a callable function. This is then
|
||||
applied by the dispatch wrapper by striping it over the input image.
|
||||
|
||||
See libswscale/ops_backend.c for the reference backend, or
|
||||
libswscale/x86/ops.c for a more complex SIMD example.
|
||||
|
||||
This overall approach has a considerable number of benefits:
|
||||
|
||||
1. It allows us to verify correctness of logic and spot semantic errors at a
|
||||
very high level, by simply looking at the sequence of operations (available
|
||||
by default at debug / verbose log level), without having to dig through the
|
||||
multiple levels of complicated, interwoven format handling code that is
|
||||
legacy swscale.
|
||||
|
||||
2. Because most of the brains lives inside the the powerful optimizer, we get
|
||||
fast paths "for free" for any suitable format conversion, rather than having
|
||||
to enumerate them one by one. SIMD code itself can be written in a very
|
||||
general way and does need to be tied to specific pixel formats - subsequent
|
||||
low-level implementations can be strung together without much overhead.
|
||||
|
||||
3. We can in the future, with relative ease, compile these operations
|
||||
down to SPIR-V (or even LLVM IR) and generate efficient GPU or
|
||||
target-machine specific implementations. This also opens the window for
|
||||
adding hardware frame support to libswscale, and even transparently using
|
||||
GPU acceleration for CPU frames.
|
||||
|
||||
4. Platform-specific SIMD can be reduced down to a comparatively small set of
|
||||
optimized routines, while still providing 100% coverage for all possible
|
||||
pixel formats and operations. (As of writing, the x86 example backend has
|
||||
about 60 unique implementations, of which 20 are trivial swizzles, 10 are
|
||||
read/write ops, 10 are pixel type conversions and the remaining 20 are the
|
||||
various logic/arithmetic ops).
|
||||
|
||||
5. Backends hide behind a layer of abstraction offering them a considerable
|
||||
deal of flexibility in how they want to implement their operations. For
|
||||
example, the x86 backend has a dedicated function for compiling compatible
|
||||
operations down to a single in-place pshufb instruction.
|
||||
|
||||
Platform specific low level data is self-contained within its own setup()
|
||||
function and private data structure, eliminating all reads into SwsContext
|
||||
or the possibility of conflicts between platforms.
|
||||
|
||||
6. We can compute an exact reference result for each operation with fixed
|
||||
precision (ff_sws_op_apply_q), and use that to e.g. measure the amount of
|
||||
error introduced by dithering, or even catch bugs in the reference C
|
||||
implementation. (In theory - currently checkasm just compares against C)

||||

||||

|
||||

|
||||

|

[ u8 .... -> ....] SWS_OP_SWIZZLE : 0123
|
||||
[ u8 .... -> ....] SWS_OP_WRITE : 3 elem(s) planar >> 0
|
||||
|
||||
This is optimized into the following sequence:
|
||||
|
||||
Optimized operation list:
|
||||
[ u8 XXXX -> +++X] SWS_OP_READ : 3 elem(s) packed >> 0
|

|
||||
[f32 ...X -> ...X] SWS_OP_LINEAR : matrix3+off3 [[0.256788 0.504129 0.097906 0 16] [-0.148223 -0.290993 112/255 0 128] [112/255 -0.367788 -0.071427 0 128] [0 0 0 1 0]]
|

[ u8 ...X -> +++X] SWS_OP_WRITE : 3 elem(s) planar >> 0
|
||||
(X = unused, + = exact, 0 = zero)
|
||||
|
||||
The extra metadata on the left of the operation list is just a dump of the
|
||||
internal state used by the optimizer during optimization. It keeps track of
|
||||
knowledge about the pixel values, such as their value range, whether or not
|
||||
they're exact integers, and so on.
|
||||
|
||||
In this example, you can see that the input values are exact (except for
|
||||
the alpha channel, which is undefined), until the first SWS_OP_LINEAR
|
||||
multiplies them by a noninteger constant. They regain their exact integer
|
||||
status only after the (truncating) conversion to U8 in the output step.
|
||||

Example of more aggressive optimization
|
||||
---------------------------------------
|
||||
|
||||
Conversion pass for gray -> rgb48:
|
||||
Unoptimized operation list:
|
||||
[ u8 .... -> ....] SWS_OP_READ : 1 elem(s) planar >> 0
|
||||
[ u8 .... -> ....] SWS_OP_SWIZZLE : 0123
|
||||
[ u8 .... -> ....] SWS_OP_RSHIFT : >> 0
|
||||
[ u8 .... -> ....] SWS_OP_CLEAR : {_ 0 0 0}
|
||||
[ u8 .... -> ....] SWS_OP_CONVERT : u8 -> f32
|
||||
[f32 .... -> ....] SWS_OP_LINEAR : luma+alpha [[1/255 0 0 0 0] [0 1 0 0 0] [0 0 1 0 0] [0 0 0 1 1]]
|
||||
[f32 .... -> ....] SWS_OP_LINEAR : matrix3 [[1 0 701/500 0 0] [1 -0.344136 -0.714136 0 0] [1 443/250 0 0 0] [0 0 0 1 0]]
|
||||
[f32 .... -> ....] SWS_OP_LINEAR : diag3 [[65535 0 0 0 0] [0 65535 0 0 0] [0 0 65535 0 0] [0 0 0 1 0]]
|
||||
[f32 .... -> ....] SWS_OP_MAX : {0 0 0 0} <= x
|
||||
[f32 .... -> ....] SWS_OP_MIN : x <= {65535 65535 65535 _}
|
||||
[f32 .... -> ....] SWS_OP_CONVERT : f32 -> u16
|
||||
[u16 .... -> ....] SWS_OP_LSHIFT : << 0
|
||||
[u16 .... -> ....] SWS_OP_SWIZZLE : 0123
|
||||
[u16 .... -> ....] SWS_OP_WRITE : 3 elem(s) packed >> 0
|
||||
|
||||
Optimized operation list:
|
||||
[ u8 XXXX -> +XXX] SWS_OP_READ : 1 elem(s) planar >> 0
|
||||
[ u8 .XXX -> +XXX] SWS_OP_CONVERT : u8 -> u16 (expand)
|
||||
[u16 .XXX -> +++X] SWS_OP_SWIZZLE : 0003
|
||||
[u16 ...X -> +++X] SWS_OP_WRITE : 3 elem(s) packed >> 0
|
||||
(X = unused, + = exact, 0 = zero)
|
||||
|
||||
Here, the optimizer has managed to eliminate all of the unnecessary linear
|
||||
operations on previously zero'd values, turn the resulting column matrix into
|
||||
a swizzle operation, avoid the unnecessary dither (and round trip via float)
|
||||
because the pixel values are guaranteed to be bit exact, and finally, turns
|
||||
the multiplication by 65535 / 255 = 257 into a simple integer expand operation.
|
||||
|
||||
As a final bonus, the x86 backend further optimizes this into a 12-byte shuffle:
|
||||
pshufb = {0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, -1, -1, -1, -1}
|
||||
|
||||
time=208 us, ref=4212 us, speedup=20.236x faster (single thread)
|
||||
time=57 us, ref=472 us, speedup=8.160x faster (multi thread)
|
||||
|
||||
Compiler and underlying implementation layer (SwsOpChain)
|
||||
---------------------------------------------------------
|
||||
|
||||
While the backend API is flexible enough to permit more exotic implementations
|
||||
(e.g. using JIT code generation), we establish a common set of helpers for use
|
||||
in "traditional" SIMD implementations.
|
||||
|
||||
The basic idea is to have one "kernel" (or implementation) per operation,
|
||||
and then just chain a list of these kernels together as separate function
|
||||
calls. For best performance, we want to keep data in vector registers in
|
||||
between function calls using a custom calling convention, thus avoiding any
|
||||
unnecessary memory accesses. Additionally, we want the per-kernel overhead to
|
||||
be as low as possible, with each kernel ideally just jumping directly into
|
||||
the next kernel.
|
||||
|
||||
As a result, we arrive at a design where we first divide the image into small
|
||||
chunks, or "blocks", and then dispatch the "chain" of kernels on each chunk in
|
||||
sequence. Each kernel processes a fixed number of pixels, with the overall
|
||||
entry point taking care of looping. Remaining pixels (the "tail") are handled
|
||||
generically by the backend-invariant dispatch code (located in ops.c), using a
|
||||
partial memcpy into a suitably sized temporary buffer.
|
||||
|
||||
To minimize the per-kernel function call overhead, we use a "continuation
|
||||
passing style" for chaining kernels. Each operation computes its result and
|
||||
then directly calls the next operation in the sequence, with the appropriate
|
||||
internal function signature.
|
||||
|
||||
The C reference backend reads data into the stack and then passes the array
|
||||
pointers to the next continuation as regular function arguments:
|
||||
|
||||
void process(GlobalContext *ctx, OpContext *op,
|
||||
block_t x, block_t y, block_t z, block_t w)
|
||||
{
|
||||
for (int i = 0; i < SWS_BLOCK_SIZE; i++)
|
||||
// do something with x[i], y[i], z[i], w[i]
|
||||
|
||||
op->next(ctx, &op[1], x, y, z, w);
|
||||
}
|
||||
|
||||
With type conversions pushing the new data onto the stack as well:
|
||||
|
||||
void convert8to16(GlobalContext *ctx, OpContext *op,
|
||||
block_t x, block_t y, block_t z, block_t w)
|
||||
{
|
||||
/* Pseudo-code */
|
||||
u16block_t x16 = (u16block_t) x;
|
||||
u16block_t y16 = (u16block_t) y;
|
||||
u16block_t z16 = (u16block_t) z;
|
||||
u16block_t w16 = (u16block_t) w;
|
||||
|
||||
op->next(ctx, &op[1], x16, y16, z16, w16);
|
||||
}
|
||||
|
||||
By contrast, the x86 backend always keeps the X/Y/Z/W values pinned in specific
|
||||
vector registers (ymm0-ymm3 for the lower half, and ymm4-ymm7 for the second
|
||||
half).
|
||||
|
||||
Each kernel additionally has access to a 32 byte per-op context storing the
|
||||
pointer to the next kernel plus 16 bytes of arbitrary private data. This is
|
||||
used during construction of the function chain to place things like small
|
||||
constants.
|
||||
|
||||
In assembly, the per-kernel overhead looks like this:
|
||||
|
||||
load $tmp, $arg1
|
||||
...
|
||||
add $arg1, 32
|
||||
jump $tmp
|
||||
|
||||
This design gives vastly better performance than the alternative of returning
|
||||
out to a central loop or "trampoline". This is partly because the order of
|
||||
kernels within a chain is always the same, so the branch predictor can easily
|
||||
remember the target address of each "jump" instruction.
|
||||
|
||||
The only way to realistically improve on this design would be to directly
|
||||
stitch the kernel body together using runtime code generation.
|
||||
|
||||
Future considerations and limitations
|
||||
-------------------------------------
|
||||
|
||||
My current prototype has a number of severe limitations and opportunities
|
||||
for improvements:
|
||||
|
||||
1. It does not handle scaling at all. I am not yet entirely sure on how I want
|
||||
to handle scaling; this includes handling of subsampled content. I have a
|
||||
number of vague ideas in my head, but nothing where I can say with certainty
|
||||
that it will work out well.
|
||||
|
||||
It's possible that we won't come up with a perfect solution here, and will
|
||||
need to decide on which set of compromises we are comfortable accepting:
|
||||
|
||||
1. Do we need the ability to scale YUV -> YUV by handling luma and chroma
|
||||
independently? When downscaling 100x100 4:2:0 to 50x50 4:4:4, should we
|
||||
support the option of reusing the chroma plane directly (even though
|
||||
this would introduce a subpixel shift for typical chroma siting)?
|
||||
|
||||
Looking towards zimg, I am also thinking that we probably also want to do
|
||||
scaling on floating point values, since this is best for both performance
|
||||
and accuracy, especially given that we need to go up to 32-bit intermediates
|
||||
during scaling anyway.
|
||||
|
||||
So far, the most promising approach seems to be to handle subsampled
|
||||
input/output as a dedicated read/write operation type; perhaps even with a
|
||||
fixed/static subsampling kernel. To avoid compromising on performance when
|
||||
chroma resampling is not necessary, the optimizer could then relax the
|
||||
pipeline to use non-interpolating read/writes when all intermediate
|
||||
operations are component-independent.
|
||||
|
||||
2. Since each operation is conceptually defined on 4-component pixels, we end
|
||||
up defining a lot of variants of each implementation for each possible
|
||||
*subset*. For example, we have four different implementations for
|
||||
SWS_OP_SCALE in my current templates:
|
||||
- op_scale_1000
|
||||
- op_scale_1001
|
||||
- op_scale_1110
|
||||
- op_scale_1111
|
||||
|
||||
This reflects the four different arrangements of pixel components that are
|
||||
typically present (or absent). While best for performance, it does turn into
|
||||
a bit of a chore when implementing these kernels.
|
||||
|
||||
The only real alternative would be to either branch inside the kernel (bad),
|
||||
or to use separate kernels for each individual component and chain them all
|
||||
together. I have not yet tested whether the latter approach would be faster
|
||||
after the latest round of refactors to the kernel glue code.
|
||||
|
||||
3. I do not yet have any support for LUTs. But when I add them, something we
|
||||
could do is have the optimized pass automatically "promote" a sequence of
|
||||
operations to LUTs. For example, any sequence that looks like:
|
||||
|
||||
1. [u8] SWS_OP_CONVERT -> X
|
||||
2. [X] ... // only per-component operations
|
||||
4. [X] SWS_OP_CONVERT -> Y
|
||||
3. [Y] SWS_OP_WRITE
|
||||
|
||||
could be replaced by a LUT with 256 entries. This is especially important
|
||||
for anything involving packed 8-bit input (e.g. rgb8, rgb4_byte).
|
||||
|
||||
We also definitely want to hook this up to the existing CMS code for
|
||||
transformations between different primaries.
|
||||
|
||||
4. Because we rely on AVRational math to generate the coefficients for
|
||||
operations, we need to be able to represent all pixel values as an
|
||||
AVRational. However, this presents a challenge for 32-bit formats (e.g.
|
||||
GRAY32, RGBA128), because their size exceeds INT_MAX, which is the maximum
|
||||
value representable by an AVRational.
|
||||
|
||||
It's possible we may want to introduce an AVRational64 for this, or
|
||||
perhaps more flexibly, extend AVRational to an AVFloating type which is
|
||||
represented as { AVRational n; int exp; }, representing n/d * 2^exp. This
|
||||
would preserve our ability to represent all pixel values exactly, while
|
||||
opening up the range arbitrarily.
|
||||
|
||||
5. Is there ever a situation where the use of floats introduces the risk of
|
||||
non bit-exact output? For this reason, and possible performance advantages,
|
||||
we may want to explore the use of a fixed-point 16 bit path as an alternative
|
||||
to the floating point math.
|
||||
|
||||
So far, I have managed to avoid any bit exactness issues inside the x86
|
||||
backend by ensuring that the order of linear operations is identical
|
||||
between the C backend and the x86 backend, but this may not be practical
|
||||
to guarantee on all backends. The x86 float code is also dramatically
|
||||
faster than the old fixed point code, so I'm tentatively optimistic about
|
||||
the lack of a need for a fixed point path.
