 ### Incompatible libraries
 
 There are certain libraries you can combine with FFmpeg whose licenses are not
 compatible with the GPL and/or the LGPL. If you wish to enable these
 libraries, even in circumstances that their license may be incompatible, pass
-`--enable-nonfree` to configure. This will cause the resulting binary to be
+`--enable-nonfree` to configure. But note that if you enable any of these
+libraries the resulting binary will be under a complex license mix that is
+more restrictive than the LGPL and that may result in additional obligations.
+It is possible that these restrictions cause the resulting binary to be
 unredistributable.
 
 The Fraunhofer FDK AAC and OpenSSL libraries are under licenses which are
 incompatible with the GPLv2 and v3. To the best of our knowledge, they are
 compatible with the LGPL.
+
+The NVENC library, while its header file is licensed under the compatible MIT
+license, requires a proprietary binary blob at run time, and is deemed to be
+incompatible with the GPL. We are not certain if it is compatible with the
+LGPL, but we require `--enable-nonfree` even with LGPL configurations in case
+it is not.

-## 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.

-_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 Stream selection
 @c man begin STREAM SELECTION
 
-@command{ffmpeg} provides the @code{-map} option for manual control of stream selection in each
-output file. Users can skip @code{-map} and let ffmpeg perform automatic stream selection as
-described below. The @code{-vn / -an / -sn / -dn} options can be used to skip inclusion of
-video, audio, subtitle and data streams respectively, whether manually mapped or automatically
-selected, except for those streams which are outputs of complex filtergraphs.
+By default, @command{ffmpeg} includes only one stream of each type (video, audio, subtitle)
+present in the input files and adds them to each output file.  It picks the
+"best" of each based upon the following criteria: for video, it is the stream
+with the highest resolution, for audio, it is the stream with the most channels, for
+subtitles, it is the first subtitle stream. In the case where several streams of
+the same type rate equally, the stream with the lowest index is chosen.
 
-@section Description
-The sub-sections that follow describe the various rules that are involved in stream selection.
-The examples that follow next show how these rules are applied in practice.
-
-While every effort is made to accurately reflect the behavior of the program, FFmpeg is under
-continuous development and the code may have changed since the time of this writing.
-
-@subsection Automatic stream selection
-
-In the absence of any map options for a particular output file, ffmpeg inspects the output
-format to check which type of streams can be included in it, viz. video, audio and/or
-subtitles. For each acceptable stream type, ffmpeg will pick one stream, when available,
-from among all the inputs.
-
-It will select that stream based upon the following criteria:
-@itemize
-@item
-for video, it is the stream with the highest resolution,
-@item
-for audio, it is the stream with the most channels,
-@item
-for subtitles, it is the first subtitle stream found but there's a caveat.
-The output format's default subtitle encoder can be either text-based or image-based,
-and only a subtitle stream of the same type will be chosen.
-@end itemize
-
-In the case where several streams of the same type rate equally, the stream with the lowest
-index is chosen.
-
-Data or attachment streams are not automatically selected and can only be included
-using @code{-map}.
-@subsection Manual stream selection
-
-When @code{-map} is used, only user-mapped streams are included in that output file,
-with one possible exception for filtergraph outputs described below.
-
-@subsection Complex filtergraphs
-
-If there are any complex filtergraph output streams with unlabeled pads, they will be added
-to the first output file. This will lead to a fatal error if the stream type is not supported
-by the output format. In the absence of the map option, the inclusion of these streams leads
-to the automatic stream selection of their types being skipped. If map options are present,
-these filtergraph streams are included in addition to the mapped streams.
-
-Complex filtergraph output streams with labeled pads must be mapped once and exactly once.
-
-@subsection Stream handling
-
-Stream handling is independent of stream selection, with an exception for subtitles described
-below. Stream handling is set via the @code{-codec} option addressed to streams within a
-specific @emph{output} file. In particular, codec options are applied by ffmpeg after the
-stream selection process and thus do not influence the latter. If no @code{-codec} option is
-specified for a stream type, ffmpeg will select the default encoder registered by the output
-file muxer.
-
-An exception exists for subtitles. If a subtitle encoder is specified for an output file, the
-first subtitle stream found of any type, text or image, will be included. ffmpeg does not validate
-if the specified encoder can convert the selected stream or if the converted stream is acceptable
-within the output format. This applies generally as well: when the user sets an encoder manually,
-the stream selection process cannot check if the encoded stream can be muxed into the output file.
-If it cannot, ffmpeg will abort and @emph{all} output files will fail to be processed.
-
-@section Examples
-
-The following examples illustrate the behavior, quirks and limitations of ffmpeg's stream
-selection methods.
-
-They assume the following three input files.
-
-@verbatim
-
-input file 'A.avi'
-      stream 0: video 640x360
-      stream 1: audio 2 channels
-
-input file 'B.mp4'
-      stream 0: video 1920x1080
-      stream 1: audio 2 channels
-      stream 2: subtitles (text)
-      stream 3: audio 5.1 channels
-      stream 4: subtitles (text)
-
-input file 'C.mkv'
-      stream 0: video 1280x720
-      stream 1: audio 2 channels
-      stream 2: subtitles (image)
-@end verbatim
-
-@subsubheading Example: automatic stream selection
-@example
-ffmpeg -i A.avi -i B.mp4 out1.mkv out2.wav -map 1:a -c:a copy out3.mov
-@end example
-There are three output files specified, and for the first two, no @code{-map} options
-are set, so ffmpeg will select streams for these two files automatically.
-
-@file{out1.mkv} is a Matroska container file and accepts video, audio and subtitle streams,
-so ffmpeg will try to select one of each type.@*
-For video, it will select @code{stream 0} from @file{B.mp4}, which has the highest
-resolution among all the input video streams.@*
-For audio, it will select @code{stream 3} from @file{B.mp4}, since it has the greatest
-number of channels.@*
-For subtitles, it will select @code{stream 2} from @file{B.mp4}, which is the first subtitle
-stream from among @file{A.avi} and @file{B.mp4}.
-
-@file{out2.wav} accepts only audio streams, so only @code{stream 3} from @file{B.mp4} is
-selected.
-
-For @file{out3.mov}, since a @code{-map} option is set, no automatic stream selection will
-occur. The @code{-map 1:a} option will select all audio streams from the second input
-@file{B.mp4}. No other streams will be included in this output file.
-
-For the first two outputs, all included streams will be transcoded. The encoders chosen will
-be the default ones registered by each output format, which may not match the codec of the
-selected input streams.
-
-For the third output, codec option for audio streams has been set
-to @code{copy}, so no decoding-filtering-encoding operations will occur, or @emph{can} occur.
-Packets of selected streams shall be conveyed from the input file and muxed within the output
-file.
-
-@subsubheading Example: automatic subtitles selection
-@example
-ffmpeg -i C.mkv out1.mkv -c:s dvdsub -an out2.mkv
-@end example
-Although @file{out1.mkv} is a Matroska container file which accepts subtitle streams, only a
-video and audio stream shall be selected. The subtitle stream of @file{C.mkv} is image-based
-and the default subtitle encoder of the Matroska muxer is text-based, so a transcode operation
-for the subtitles is expected to fail and hence the stream isn't selected. However, in
-@file{out2.mkv}, a subtitle encoder is specified in the command and so, the subtitle stream is
-selected, in addition to the video stream. The presence of @code{-an} disables audio stream
-selection for @file{out2.mkv}.
-
-@subsubheading Example: unlabeled filtergraph outputs
-@example
-ffmpeg -i A.avi -i C.mkv -i B.mp4 -filter_complex "overlay" out1.mp4 out2.srt
-@end example
-A filtergraph is setup here using the @code{-filter_complex} option and consists of a single
-video filter. The @code{overlay} filter requires exactly two video inputs, but none are
-specified, so the first two available video streams are used, those of @file{A.avi} and
-@file{C.mkv}. The output pad of the filter has no label and so is sent to the first output file
-@file{out1.mp4}. Due to this, automatic selection of the video stream is skipped, which would
-have selected the stream in @file{B.mp4}. The audio stream with most channels viz. @code{stream 3}
-in @file{B.mp4}, is chosen automatically. No subtitle stream is chosen however, since the MP4
-format has no default subtitle encoder registered, and the user hasn't specified a subtitle encoder.
-
-The 2nd output file, @file{out2.srt}, only accepts text-based subtitle streams. So, even though
-the first subtitle stream available belongs to @file{C.mkv}, it is image-based and hence skipped.
-The selected stream, @code{stream 2} in @file{B.mp4}, is the first text-based subtitle stream.
-
-@subsubheading Example: labeled filtergraph outputs
-@example
-ffmpeg -i A.avi -i B.mp4 -i C.mkv -filter_complex "[1:v]hue=s=0[outv];overlay;aresample" \
-       -map '[outv]' -an        out1.mp4 \
-                                out2.mkv \
-       -map '[outv]' -map 1:a:0 out3.mkv
-@end example
-
-The above command will fail, as the output pad labelled @code{[outv]} has been mapped twice.
-None of the output files shall be processed.
-
-@example
-ffmpeg -i A.avi -i B.mp4 -i C.mkv -filter_complex "[1:v]hue=s=0[outv];overlay;aresample" \
-       -an        out1.mp4 \
-                  out2.mkv \
-       -map 1:a:0 out3.mkv
-@end example
-
-This command above will also fail as the hue filter output has a label, @code{[outv]},
-and hasn't been mapped anywhere.
-
-The command should be modified as follows,
-@example
-ffmpeg -i A.avi -i B.mp4 -i C.mkv -filter_complex "[1:v]hue=s=0,split=2[outv1][outv2];overlay;aresample" \
-        -map '[outv1]' -an        out1.mp4 \
-                                  out2.mkv \
-        -map '[outv2]' -map 1:a:0 out3.mkv
-@end example
-The video stream from @file{B.mp4} is sent to the hue filter, whose output is cloned once using
-the split filter, and both outputs labelled. Then a copy each is mapped to the first and third
-output files.
-
-The overlay filter, requiring two video inputs, uses the first two unused video streams. Those
-are the streams from @file{A.avi} and @file{C.mkv}. The overlay output isn't labelled, so it is
-sent to the first output file @file{out1.mp4}, regardless of the presence of the @code{-map} option.
-
-The aresample filter is sent the first unused audio stream, that of @file{A.avi}. Since this filter
-output is also unlabelled, it too is mapped to the first output file. The presence of @code{-an}
-only suppresses automatic or manual stream selection of audio streams, not outputs sent from
-filtergraphs. Both these mapped streams shall be ordered before the mapped stream in @file{out1.mp4}.
-
-The video, audio and subtitle streams mapped to @code{out2.mkv} are entirely determined by
-automatic stream selection.
-
-@file{out3.mkv} consists of the cloned video output from the hue filter and the first audio
-stream from @file{B.mp4}.

 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.
-

-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.
