└────────────────────────────────────────────┘
The FFmpeg Project proudly presents FFmpeg 5.1 "Riemann" LTS, about 6
months after the release of FFmpeg 5.0, our first Long Term Support
release. While several past FFmpeg releases have enjoyed long term
support, this is the first release where such an intention is made
clear at release.
The FFmpeg Project proudly presents FFmpeg 6.0 "Von Neumann", about 6
months after the release of FFmpeg 5.1.
A complete Changelog is available at the root of the project, and the
complete Git history on https://git.ffmpeg.org/gitweb/ffmpeg.git

@chapter Notes for external developers
@chapter Introduction
This document is mostly useful for internal FFmpeg developers.
External developers who need to use the API in their application should
refer to the API doxygen documentation in the public headers, and
check the examples in @file{doc/examples} and in the source code to
see how the public API is employed.
This text is concerned with the development @emph{of} FFmpeg itself. Information
on using the FFmpeg libraries in other programs can be found elsewhere, e.g. in:
@itemize @bullet
@item
the installed header files
@item
@url{http://ffmpeg.org/doxygen/trunk/index.html, the Doxygen documentation}
generated from the headers
@item
the examples under @file{doc/examples}
@end itemize
You can use the FFmpeg libraries in your commercial program, but you
are encouraged to @emph{publish any patch you make}. In this case the
best way to proceed is to send your patches to the ffmpeg-devel
mailing list following the guidelines illustrated in the remainder of
this document.
If you modify FFmpeg code for your own use case, you are highly encouraged to
@emph{submit your changes back to us}, using this document as a guide. There are
both pragmatic and ideological reasons to do so:
@itemize @bullet
@item
Maintaining external changes to keep up with upstream development is
time-consuming and error-prone. With your code in the main tree, it will be
maintained by FFmpeg developers.
@item
FFmpeg developers include leading experts in the field who can find bugs or
design flaws in your code.
@item
By supporting the project you find useful you ensure it continues to be
maintained and developed.
@end itemize
For more detailed legal information about the use of FFmpeg in
external programs read the @file{LICENSE} file in the source tree and
consult @url{https://ffmpeg.org/legal.html}.
@chapter Contributing
@section Contributing code
There are 2 ways by which code gets into FFmpeg:
@itemize @bullet
@item Submitting patches to the ffmpeg-devel mailing list.
See @ref{Submitting patches} for details.
@item Directly committing changes to the main tree.
@end itemize
Whichever way, changes should be reviewed by the maintainer of the code
before they are committed. And they should follow the @ref{Coding Rules}.
All proposed code changes should be submitted for review to
@url{mailto:ffmpeg-devel@@ffmpeg.org, the development mailing list}, as
described in more detail in the @ref{Submitting patches} chapter. The code
should comply with the @ref{Development Policy} and follow the @ref{Coding Rules}.
The developer making the commit and the author are responsible for their changes
and should try to fix issues their commit causes.

@section C language features
FFmpeg is programmed in the ISO C99 language, extended with:
@itemize @bullet
@item
Atomic operations from C11 @file{stdatomic.h}. They are emulated on
architectures/compilers that do not support them, so all FFmpeg-internal code
may use atomics without any extra checks. However, @file{stdatomic.h} must not
be included in public headers, so they stay C99-compatible.
@end itemize
Compiler-specific extensions may be used with good reason, but must not be
depended on, i.e. the code must still compile and work with compilers lacking
the extension.
The following C99 features must not be used anywhere in the codebase:
@itemize @bullet
@item
variable-length arrays;
@item
complex numbers;
@item
mixed statements and declarations.

@section C language features
FFmpeg is programmed in the ISO C90 language with a few additional
features from ISO C99, namely:
@itemize @bullet
@item
the @samp{inline} keyword;
@item
@samp{//} comments;
@item
designated struct initializers (@samp{struct s x = @{ .i = 17 @};});
@item
compound literals (@samp{x = (struct s) @{ 17, 23 @};}).
@item
for loops with variable definition (@samp{for (int i = 0; i < 8; i++)});
@item
Variadic macros (@samp{#define ARRAY(nb, ...) (int[nb + 1])@{ nb, __VA_ARGS__ @}});
@item
Implementation defined behavior for signed integers is assumed to match the
expected behavior for two's complement. Non representable values in integer
casts are binary truncated. Shift right of signed values uses sign extension.
@end itemize
These features are supported by all compilers we care about, so we will not
accept patches to remove their use unless they absolutely do not impair
clarity and performance.
All code must compile with recent versions of GCC and a number of other
currently supported compilers. To ensure compatibility, please do not use
additional C99 features or GCC extensions. Especially watch out for:
@itemize @bullet
@item
mixing statements and declarations;
@item
@samp{long long} (use @samp{int64_t} instead);
@item
@samp{__attribute__} not protected by @samp{#ifdef __GNUC__} or similar;
@item
GCC statement expressions (@samp{(x = (@{ int y = 4; y; @})}).
@end itemize
@section Naming conventions
All names should be composed with underscores (_), not CamelCase. For example,
@samp{avfilter_get_video_buffer} is an acceptable function name and
@samp{AVFilterGetVideo} is not. The exception from this are type names, like
for example structs and enums; they should always be in CamelCase.
There are the following conventions for naming variables and functions:
Names of functions, variables, and struct members must be lowercase, using
underscores (_) to separate words. For example, @samp{avfilter_get_video_buffer}
is an acceptable function name and @samp{AVFilterGetVideo} is not.
Struct, union, enum, and typedeffed type names must use CamelCase. All structs
and unions should be typedeffed to the same name as the struct/union tag, e.g.
@code{typedef struct AVFoo @{ ... @} AVFoo;}. Enums are typically not
typedeffed.
Enumeration constants and macros must be UPPERCASE, except for macros
masquerading as functions, which should use the function naming convention.
All identifiers in the libraries should be namespaced as follows:
@itemize @bullet
@item
For local variables no prefix is required.
No namespacing for identifiers with file and lower scope (e.g. local variables,
static functions), and struct and union members,
@item
For file-scope variables and functions declared as @code{static}, no prefix
is required.
@item
For variables and functions visible outside of file scope, but only used
internally by a library, an @code{ff_} prefix should be used,
e.g. @samp{ff_w64_demuxer}.
The @code{ff_} prefix must be used for variables and functions visible outside
of file scope, but only used internally within a single library, e.g.
@samp{ff_w64_demuxer}. This prevents name collisions when FFmpeg is statically
linked.
@item
For variables and functions visible outside of file scope, used internally
across multiple libraries, use @code{avpriv_} as prefix, for example,
@samp{avpriv_report_missing_feature}.
@item
All other internal identifiers, like private type or macro names, should be
namespaced only to avoid possible internal conflicts. E.g. @code{H264_NAL_SPS}
vs. @code{HEVC_NAL_SPS}.
@item
Each library has its own prefix for public symbols, in addition to the
commonly used @code{av_} (@code{avformat_} for libavformat,
@code{avcodec_} for libavcodec, @code{swr_} for libswresample, etc).
Check the existing code and choose names accordingly.
Note that some symbols without these prefixes are also exported for
retro-compatibility reasons. These exceptions are declared in the
@code{lib<name>/lib<name>.v} files.
@item
Other public identifiers (struct, union, enum, macro, type names) must use their
library's public prefix (@code{AV}, @code{Sws}, or @code{Swr}).
@end itemize
Furthermore, name space reserved for the system should not be invaded.

# 15-point AVX FFT transform
The 15-point transform is based on the following unrolling. The input
must be permuted via the following loop:
``` C
for (int k = 0; k < s->sub[0].len; k++) {
int cnt = 0;
int tmp[15];
memcpy(tmp, &s->map[k*15], 15*sizeof(*tmp));
for (int i = 1; i < 15; i += 3) {
s->map[k*15 + cnt] = tmp[i];
cnt++;
}
for (int i = 2; i < 15; i += 3) {
s->map[k*15 + cnt] = tmp[i];
cnt++;
}
for (int i = 0; i < 15; i += 3) {
s->map[k*15 + cnt] = tmp[i];
cnt++;
}
memmove(&s->map[k*15 + 7], &s->map[k*15 + 6], 4*sizeof(int));
memmove(&s->map[k*15 + 3], &s->map[k*15 + 1], 4*sizeof(int));
s->map[k*15 + 1] = tmp[2];
s->map[k*15 + 2] = tmp[0];
}
```
This separates the ACs from the DCs and flips the SIMD direction to
performing 5x3pt transforms at once, followed by 3x5pt transforms.
