-*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

-@section MediaCodec
-
-MediaCodec encoder wrapper enables hardware-accelerated video encoding on
-Android device. It supports H.264, H.265 (HEVC), VP8, VP9, MPEG-4, and AV1
-encoding (whether works or not is device dependent).
-
-Android provides two sets of APIs: Java MediaCodec and NDK MediaCodec. The
-MediaCodec encoder wrapper supports both. Note that the NDK MediaCodec API
-operates without requiring JVM, but may fail to function outside the JVM
-environment due to dependencies on system framework services, particularly
-after Android 15.
-
-@table @option
-@item ndk_codec @var{boolean}
-Use the NDK-based MediaCodec API instead of the Java API. Enabled by default
-if @code{av_jni_get_java_vm()} return NULL.
-
-@item ndk_async @var{boolean}
-Use NDK MediaCodec in async mode. Async mode has less overhead than poll in a
-loop in sync mode. The drawback of async mode is AV_CODEC_FLAG_GLOBAL_HEADER
-doesn't work (use extract_extradata bsf when necessary). It doesn't work and
-will be disabled automatically on devices below Android 8.0.
-
-@item codec_name @var{string}
-A codec type can have multiple implementations on a single device, this option
-specify which backend to use (via MediaCodec createCodecByName API). It's NULL
-by default, and encoder is created by createEncoderByType.

-@end table
-
-@item pts_as_dts @var{boolean}
-Use PTS as DTS. This is a workaround since MediaCodec API doesn't provide
-decoding timestamp. It is enabled automatically if B frame is 0.
-
-@item operating_rate @var{integer}
-The desired operating rate that the codec will need to operate at, zero for
-unspecified. This is used for cases like high-speed/slow-motion video capture,
-where the video encoder format contains the target playback rate (e.g. 30fps),
-but the component must be able to handle the high operating capture rate (e.g.
-240fps). This rate will be used by codec for resource planning and setting the
-operating points.

-The following wrappers for encoders in the MediaFoundation framework are
-available:
-
-@itemize
-@item h264_mf
-@item hevc_mf
-@item av1_mf
-@end itemize
-
-These support both software and hardware encoding.
-
+This provides wrappers to encoders (both audio and video) in the
+MediaFoundation framework. It can access both SW and HW encoders.
 Video encoders can take input in either of nv12 or yuv420p form
 (some encoders support both, some support only either - in practice,
 nv12 is the safer choice, especially among HW encoders).

-Hardware-accelerated encoding requires D3D11, including hardware
-scaling capabilities through the scale_d3d11 filter.

-To list all available options for the MediaFoundation encoders, use:

@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.

+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:
+----------------------------------------------
+

-@table @option
-
-@item cache_dir
-Path to the directory where cache files are stored. This option is required.
-
-@item block_shift
-Shift factor (log2) of the block size used for internal reads/writes. Defaults
-to 15, i.e. 32KB blocks. If this does not match the value that was specified
-when an existing cache file was created, the previously specified value will
-be used instead.
-
-@item read_only
-If true, use the shared cache for reads but don't write any new blocks to it.
-Default is false. Note that even with this option enabled, the cache file will
-be initialized if it does not already exist.
-
-@item cache_verify
-If true, verify any data read from the cache against the underlying input
-stream, and report any mismatches. Note that this will make the cache layer
-effectively useless. This is purely a debug option.
-
-@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.
-
-If set to zero, no waiting is done and all processes will immediately race
-to try and fetch the same missing blocks themselves. Defaults to 10000 (10 ms).
-
-@item retry_errors
-If true (the default), transient read errors from the underlying input stream
-are ignored and retried again. If false, any blocks that previously failed
-being read from will be treated as permanently inaccessible.
-
-@item retry_corrupt
-If true (the default), blocks whose contents fail the CRC integrity check are
-re-fetched from the underlying input stream, overwriting the corrupt cached
-data. If false, cache corruption is treated as a fatal read error.
