-*What is CVSS*
-    The Common Vulnerability Scoring System (CVSS) is an open, industry-standard framework used to measure and communicate the severity of software vulnerabilities, ranging from 0.0 to 10.0.
-
-*Why we need this Document*
-    It is important that FFmpeg CVEs have consistent and correct CVSS, not only for the obvious reason that one can recognize the severity of an issue at first glance.
-    But also as these numbers form the basis of rewards paid in bug bounty systems. Inconsistent CVSS could lead to unfair payouts.
-
-*What is this Document*
-    Prior 2026, FFmpeg had no guideline about CVSS.
-    This document describes how to select the CVSS for a FFmpeg related CVE. It currently only covers the Base Score.
-
-*What is the CVSS Base Score*
-    AV Attack Vector    (Network, Adjacent, Local, Physical)
-    AC Attack Complexity (Low, High)
-    PR Privileges Required (None, Low, High)
-    UI User Interaction (None, Required)
-    S  Scope (Unchanged, Changed)
-    C  Confidentiality (None, Low, High)
-    I  Integrity (None, Low, High)
-    A  Availability (None, Low, High)
-
-
-*Things people have set incorrectly*
-
-Below are general guidelines and in specific cases other things may apply.
-
-Attack Vector.
-    Quote from https://www.first.org/cvss/v3.1/user-guide
-        "Specifically, analysts should only score for Network or Adjacent when a vulnerability is bound to the network stack.
-         Vulnerabilities which require user interaction to download or receive malicious content (which could also be delivered locally, e.g., via USB drives) should be scored as Local."
-
-Availability.
-    FFmpeg Crashes -> AVAILABILITY IMPACT: Low
-    FFmpeg is frequently used as a short-lived, single-run process instead of a continuously running service that handles ongoing streams of user input. In that usage model, a crash usually causes only limited disruption.
-
-User Interaction
-    Please consider if an attacker can actually set the parameters required for an attack.
-    In general arbitrary filter parameters cannot be set by an attacker and require the user/account owner/admin to set them

@chapter Using FATE from your FFmpeg source directory

-If you want to run FATE on your machine, FFmpeg needs to be configured first.
-You may specify the location of samples during configuration by adding the
-argument @code{--samples=/path/to/fate-suite}.
+If you want to run FATE on your machine you need to have the samples
+in place. You can get the samples via the build target fate-rsync.
+Use this command from the top-level source directory:

@example
-./configure --enable-somelib --samples=/path/to/fate-suite
+make fate-rsync SAMPLES=fate-suite/
+make fate       SAMPLES=fate-suite/
@end example

-After successful configuration, you need to add and/or update the samples in place:
+The above commands set the samples location by passing a makefile
+variable via command line. It is also possible to set the samples
+location at source configuration time by invoking configure with
+@option{--samples=<path to the samples directory>}. Afterwards you can
+invoke the makefile targets without setting the @var{SAMPLES} makefile
+variable. This is illustrated by the following commands:

@example
-make fate-rsync
-@end example
-
-Now you are ready to run FATE:
-
-@example
-make fate
-@end example
-
-See @ref{makefile variables} for a list of arguments that can be added.
-
-If you did not set the samples path during configuration, or if you wish to
-override it just before starting FATE, you can do so in one of three ways.
-
-Either by setting a make variable:
-
-@example
-make fate-rsync SAMPLES=/path/to/fate-suite
-make fate       SAMPLES=/path/to/fate-suite
-@end example
-
-or by setting an environment variable for the current session:
-
-@example
-export FATE_SAMPLES=/path/to/fate-suite
+./configure --samples=fate-suite/
 make fate-rsync
 make fate
@end example

-or in isolation for a single command by prepending it:
+Yet another way to tell FATE about the location of the sample
+directory is by making sure the environment variable FATE_SAMPLES
+contains the path to your samples directory. This can be achieved
+by e.g. putting that variable in your shell profile or by setting
+it in your interactive session.

@example
-FATE_SAMPLES=/path/to/fate-suite make fate-rsync
-FATE_SAMPLES=/path/to/fate-suite make fate
+FATE_SAMPLES=fate-suite/ make fate
@end example

-This variable can also be set in your shell profile to make it permanent.
-
@float NOTE
 Do not put a '~' character in the samples path to indicate a home
 directory. Because of shell nuances, this will cause FATE to fail.
-Also, on Windows the path has to be relative to the build path
-which in this case is the FFmpeg source directory.
@end float

-
-One demuxer instance is created for each @option{-i} option, and sends encoded

-@emph{Decoders} receive encoded (compressed) @emph{packets} for an audio, video,

-@section Streamcopy
-The simplest pipeline in @command{ffmpeg} is single-stream
-@emph{streamcopy}, that is copying one @emph{input elementary stream}'s packets
-without decoding, filtering, or encoding them. As an example, consider an input
-file called @file{INPUT.mkv} with 3 elementary streams, from which we take the
-second and write it to file @file{OUTPUT.mp4}. A schematic representation of
-such a pipeline looks like this:
-@verbatim

-The above pipeline can be constructed with the following commandline:
-@example
-ffmpeg -i INPUT.mkv -map 0:1 -c copy OUTPUT.mp4
-@end example
-
-In this commandline
-@itemize
-
-@item
-there is a single input @file{INPUT.mkv};
-
-@item
-there are no input options for this input;
-
-@item
-there is a single output @file{OUTPUT.mp4};
-

-there are two output options for this output:
-
-@itemize
-@item
-@code{-map 0:1} selects the input stream to be used - from input with index 0
-(i.e. the first one) the stream with index 1 (i.e. the second one);
-
-@item
-@code{-c copy} selects the @code{copy} encoder, i.e. streamcopy with no decoding
-or encoding.

-Streamcopy is useful for changing the elementary stream count, container format,
-or modifying container-level metadata. Since there is no decoding or encoding,
-it is very fast and there is no quality loss. However, it might not work in some
-cases because of a variety of factors (e.g. certain information required by the
-target container is not available in the source). Applying filters is obviously
-also impossible, since filters work on decoded frames.
-
-More complex streamcopy scenarios can be constructed - e.g. combining streams
-from two input files into a single output:

-output file even though their values are the same. This is because non-global
-options (which is most of them) only apply in the context of the file before

-
-These  examples can of course be further generalized into arbitrary remappings
-of any number of inputs into any number of outputs.
-
-@section Transcoding
-@emph{Transcoding} is the process of decoding a stream and then encoding it
-again. Since encoding tends to be computationally expensive and in most cases
-degrades the stream quality (i.e. it is @emph{lossy}), you should only transcode
-when you need to and perform streamcopy otherwise. Typical reasons to transcode
-are:
-
-@itemize
-@item
-applying filters - e.g. resizing, deinterlacing, or overlaying video; resampling
-or mixing audio;
-
-@item
-you want to feed the stream to something that cannot decode the original codec.
-@end itemize
-Note that @command{ffmpeg} will transcode all audio, video, and subtitle streams
-unless you specify @option{-c copy} for them.
-
-Consider an example pipeline that reads an input file with one audio and one
-video stream, transcodes the video and copies the audio into a single output
-file. This can be schematically represented as follows
-@verbatim

-@example

-streams and apply different values of the @option{-c} option to them; see the
-@ref{Stream specifiers} section for more details.
+@command{ffmpeg} calls the libavformat library (containing demuxers) to read
+input files and get packets containing encoded data from them. When there are
+multiple input files, @command{ffmpeg} tries to keep them synchronized by
+tracking lowest timestamp on any active input stream.

+Encoded packets are then passed to the decoder (unless streamcopy is selected
+for the stream, see further for a description). The decoder produces
+uncompressed frames (raw video/PCM audio/...) which can be processed further by
+filtering (see next section). After filtering, the frames are passed to the
+encoder, which encodes them and outputs encoded packets. Finally, those are
+passed to the muxer, which writes the encoded packets to the output file.

@section Filtering
-
-When transcoding, audio and video streams can be filtered before encoding, with
-either a @emph{simple} or @emph{complex} filtergraph.
+Before encoding, @command{ffmpeg} can process raw audio and video frames using
+filters from the libavfilter library. Several chained filters form a filter
+graph. @command{ffmpeg} distinguishes between two types of filtergraphs:
+simple and complex.

@subsection Simple filtergraphs
-
 Simple filtergraphs are those that have exactly one input and output, both of
-the same type (audio or video). They are configured with the per-stream
-@option{-filter} option (with @option{-vf} and @option{-af} aliases for
-@option{-filter:v} (video) and @option{-filter:a} (audio) respectively). Note
-that simple filtergraphs are tied to their output stream, so e.g. if you have
-multiple audio streams, @option{-af} will create a separate filtergraph for each
-one.
+the same type. In the above diagram they can be represented by simply inserting
+an additional step between decoding and encoding:

-Taking the transcoding example from above, adding filtering (and omitting audio,
-for clarity) makes it look like this:

-@subsection Complex filtergraphs
+Simple filtergraphs are configured with the per-stream @option{-filter} option
+(with @option{-vf} and @option{-af} aliases for video and audio respectively).
+A simple filtergraph for video can look for example like this:

+@verbatim
+ _______        _____________        _______        ________
+|       |      |             |      |       |      |        |
+| input | ---> | deinterlace | ---> | scale | ---> | output |
+|_______|      |_____________|      |_______|      |________|
+
+@end verbatim
+
+Note that some filters change frame properties but not frame contents. E.g. the
+@code{fps} filter in the example above changes number of frames, but does not
+touch the frame contents. Another example is the @code{setpts} filter, which
+only sets timestamps and otherwise passes the frames unchanged.
+
+@subsection Complex filtergraphs
 Complex filtergraphs are those which cannot be described as simply a linear
-processing chain applied to one stream. This is the case, for example, when the
-graph has more than one input and/or output, or when output stream type is
-different from input. Complex filtergraphs are configured with the
-@option{-filter_complex} option. Note that this option is global, since a
-complex filtergraph, by its nature, cannot be unambiguously associated with a
-single stream or file. Each instance of @option{-filter_complex} creates a new
-complex filtergraph, and there can be any number of them.

+|_________| \                  |          |

+ _________   /  |_________|    |__________|
+|         | /
+| input 2 |/
+|_________|
+
+@end verbatim
+
+Complex filtergraphs are configured with the @option{-filter_complex} option.
+Note that this option is global, since a complex filtergraph, by its nature,
+cannot be unambiguously associated with a single stream or file.
+
+The @option{-lavfi} option is equivalent to @option{-filter_complex}.

 A trivial example of a complex filtergraph is the @code{overlay} filter, which
 has two video inputs and one video output, containing one video overlaid on top
 of the other. Its audio counterpart is the @code{amix} filter.

-@anchor{Loopback decoders}
+@section Stream copy
+Stream copy is a mode selected by supplying the @code{copy} parameter to the
+@option{-codec} option. It makes @command{ffmpeg} omit the decoding and encoding
+step for the specified stream, so it does only demuxing and muxing. It is useful
+for changing the container format or modifying container-level metadata. The
+diagram above will, in this case, simplify to this:
+
+@verbatim
+ _______              ______________            ________
+|       |            |              |          |        |

+| file  | ---------> | packets      | -------> | file   |
+|_______|            |______________|          |________|
+
+@end verbatim
+
+Since there is no decoding or encoding, it is very fast and there is no quality
+loss. However, it might not work in some cases because of many factors. Applying
+filters is obviously also impossible, since filters work on uncompressed data.

+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)

-WebRTC (Real-Time Communication) muxer that supports sub-second latency streaming according to
-the WHIP (WebRTC-HTTP ingestion protocol) specification.
-
-This is an experimental feature.
-
-It uses HTTP as a signaling protocol to exchange SDP capabilities and ICE lite candidates. Then,
-it uses STUN binding requests and responses to establish a session over UDP. Subsequently, it
-initiates a DTLS handshake to exchange the SRTP encryption keys. Lastly, it splits video and
-audio frames into RTP packets and encrypts them using SRTP.
-
-Ensure that you use H.264 without B frames and Opus for the audio codec. For example, to convert
-an input file with @command{ffmpeg} to WebRTC:
-@example
-ffmpeg -re -i input.mp4 -acodec libopus -ar 48000 -ac 2 \

-  -f whip "http://localhost:1985/rtc/v1/whip/?app=live&stream=livestream"

-the input stream to a file in the specified directory. This is similar to
-@ref{cache}, but with a persistent cache on disk that may be shared between
-multiple processes or demuxers, even concurrently.
-
-The filename of the cache is obtained by hashing the input URL, so there is
-some risk of collision if the same URL is used for different content (e.g.
-as a result of extra POST data being used to select the stream ID). To avoid
-this, make sure to only use this protocol for URLs that uniquely identify

-
-@item cache_timeout
-If set to a nonzero value, specifies the maximum time (in microseconds) to wait
-for data to become available, if another process is currently trying to fetch
-and cache the same block at the same time. If this timeout elapses, it's
-assumed that the other process may have gotten stuck or died in the meantime.

-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_reinit() initially and on 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 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)

-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.

-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.
