@chapter Unix-like
|
|
|
|
Some parts of FFmpeg cannot be built with version 2.15 of the GNU
|
|
assembler which is still provided by a few AMD64 distributions. To
|
|
make sure your compiler really uses the required version of gas
|
|
after a binutils upgrade, run:
|
|
|
|
@example
|
|
$(gcc -print-prog-name=as) --version
|
|
@end example
|
|
|
|
If not, then you should install a different compiler that has no
|
|
hard-coded path to gas. In the worst case pass @code{--disable-asm}
|
|
to configure.
|
|
|
|
@section Advanced linking configuration
|
|
|
|
If you compiled FFmpeg libraries statically and you want to use them to
|
|
build your own shared library, you may need to force PIC support (with
|
|
@code{--enable-pic} during FFmpeg configure) and add the following option
|
|
to your project LDFLAGS:
|
|
|
|
@example
|
|
-Wl,-Bsymbolic
|
|
@end example
|
|
|
|
If your target platform requires position independent binaries, you should
|
|
pass the correct linking flag (e.g. @code{-pie}) to @code{--extra-ldexeflags}.
|
|
|
|
@section BSD
|
|
|
|
BSD make will not build FFmpeg, you need to install and use GNU Make
|
|
(@command{gmake}).
|
|
|
|
@section (Open)Solaris
|
|
|
|
GNU Make is required to build FFmpeg, so you have to invoke (@command{gmake}),
|
|
standard Solaris Make will not work. When building with a non-c99 front-end
|
|
(gcc, generic suncc) add either @code{--extra-libs=/usr/lib/values-xpg6.o}
|
|
or @code{--extra-libs=/usr/lib/64/values-xpg6.o} to the configure options
|
|
since the libc is not c99-compliant by default. The probes performed by
|
|
configure may raise an exception leading to the death of configure itself
|
|
due to a bug in the system shell. Simply invoke a different shell such as
|
|
bash directly to work around this:
|
|
|
|
@example
|
|
bash ./configure
|
|
@end example
|
|
|
|

@section Darwin (Mac OS X, iPhone)
|
|
|
|
The toolchain provided with Xcode is sufficient to build the basic
|
|
unaccelerated code.
|
|
|
|
Mac OS X on PowerPC or ARM (iPhone) requires a preprocessor from
|
|
@url{https://github.com/FFmpeg/gas-preprocessor} or
|
|
@url{https://github.com/yuvi/gas-preprocessor}(currently outdated) to build the optimized
|
|
assembly functions. Put the Perl script somewhere
|
|
in your PATH, FFmpeg's configure will pick it up automatically.
|
|
|
|
Mac OS X on amd64 and x86 requires @command{yasm} to build most of the
|
|
optimized assembly functions. @uref{http://www.finkproject.org/, Fink},
|
|
@uref{http://www.gentoo.org/proj/en/gentoo-alt/prefix/bootstrap-macos.xml, Gentoo Prefix},
|
|
@uref{https://mxcl.github.com/homebrew/, Homebrew}
|
|
or @uref{http://www.macports.org, MacPorts} can easily provide it.

@section Native Windows compilation using MinGW or MinGW-w64
|
|
|
|
FFmpeg can be built to run natively on Windows using the MinGW-w64
|
|
toolchain. Install the latest versions of MSYS2 and MinGW-w64 from
|
|
@url{http://msys2.github.io/} and/or @url{http://mingw-w64.sourceforge.net/}.
|
|
You can find detailed installation instructions in the download section and
|
|
the FAQ.
|
|
|
|
Notes:
|
|
|
|
@itemize
|
|
|
|
@item Building for the MSYS environment is discouraged, MSYS2 provides a full
|
|
MinGW-w64 environment through @file{mingw64_shell.bat} or
|
|
@file{mingw32_shell.bat} that should be used instead of the environment
|
|
provided by @file{msys2_shell.bat}.
|
|
|
|
@item Building using MSYS2 can be sped up by disabling implicit rules in the
|
|
Makefile by calling @code{make -r} instead of plain @code{make}. This
|
|
speed up is close to non-existent for normal one-off builds and is only
|
|
noticeable when running make for a second time (for example during
|
|
@code{make install}).
|
|
|
|
@item In order to compile FFplay, you must have the MinGW development library
|
|
of @uref{http://www.libsdl.org/, SDL} and @code{pkg-config} installed.
|
|
|
|
@item By using @code{./configure --enable-shared} when configuring FFmpeg,
|
|
you can build the FFmpeg libraries (e.g. libavutil, libavcodec,
|
|
libavformat) as DLLs.
|
|
|
|
@end itemize

|
|
@subsection Native Windows compilation using MSYS2
|
|
|
|
The MSYS2 MinGW-w64 environment provides ready to use toolchains and dependencies
|
|
through @command{pacman}.
|
|
|
|
Make sure to use @file{mingw64_shell.bat} or @file{mingw32_shell.bat} to have
|
|
the correct MinGW-w64 environment. The default install provides shortcuts to
|
|
them under @command{MinGW-w64 Win64 Shell} and @command{MinGW-w64 Win32 Shell}.
|
|
|
|
@example
|
|
# normal msys2 packages
|
|
pacman -S make pkgconf diffutils
|
|
|
|
# mingw-w64 packages and toolchains
|
|
pacman -S mingw-w64-x86_64-yasm mingw-w64-x86_64-gcc mingw-w64-x86_64-SDL
|
|
@end example
|
|
|
|
To target 32 bits replace @code{x86_64} with @code{i686} in the command above.
|
|
|
|
@section Microsoft Visual C++ or Intel C++ Compiler for Windows
|
|
|
|
FFmpeg can be built with MSVC 2012 or earlier using a C99-to-C89 conversion utility
|
|
and wrapper, or with MSVC 2013 and ICL natively.
|
|
|
|
You will need the following prerequisites:
|
|
|
|
@itemize
|
|
@item @uref{https://github.com/libav/c99-to-c89/, C99-to-C89 Converter & Wrapper}
|
|
(if using MSVC 2012 or earlier)
|
|
@item @uref{http://code.google.com/p/msinttypes/, msinttypes}
|
|
(if using MSVC 2012 or earlier)
|
|
@item @uref{http://msys2.github.io/, MSYS2}
|
|
@item @uref{http://yasm.tortall.net/, YASM}
|
|
(Also available via MSYS2's package manager.)
|
|
@end itemize
|
|
|
|
To set up a proper environment in MSYS2, you need to run @code{msys_shell.bat} from
|
|
the Visual Studio or Intel Compiler command prompt.
|
|
|
|
Place @code{yasm.exe} somewhere in your @code{PATH}. If using MSVC 2012 or
|
|
earlier, place @code{c99wrap.exe} and @code{c99conv.exe} somewhere in your
|
|
@code{PATH} as well.
|
|
|
|
Next, make sure any other headers and libs you want to use, such as zlib, are
|
|
located in a spot that the compiler can see. Do so by modifying the @code{LIB}
|
|
and @code{INCLUDE} environment variables to include the @strong{Windows-style}
|
|
paths to these directories. Alternatively, you can try to use the
|
|
@code{--extra-cflags}/@code{--extra-ldflags} configure options. If using MSVC
|
|
2012 or earlier, place @code{inttypes.h} somewhere the compiler can see too.
|
|
|
|
Finally, run:
|
|
|
|
@example
|
|
For MSVC:
|
|
./configure --toolchain=msvc
|
|
|
|
For ICL:
|
|
./configure --toolchain=icl
|
|
|
|
make
|
|
make install
|
|
@end example
|
|
|
|
If you wish to compile shared libraries, add @code{--enable-shared} to your
|
|
configure options. Note that due to the way MSVC and ICL handle DLL imports and
|
|
exports, you cannot compile static and shared libraries at the same time, and
|
|
enabling shared libraries will automatically disable the static ones.
|
|
|
|
Notes:
|
|
|
|
@itemize
|
|
|
|
@item If you wish to build with zlib support, you will have to grab a compatible
|
|
zlib binary from somewhere, with an MSVC import lib, or if you wish to link
|
|
statically, you can follow the instructions below to build a compatible
|
|
@code{zlib.lib} with MSVC. Regardless of which method you use, you must still
|
|
follow step 3, or compilation will fail.
|
|
@enumerate
|
|
@item Grab the @uref{http://zlib.net/, zlib sources}.
|
|
@item Edit @code{win32/Makefile.msc} so that it uses -MT instead of -MD, since
|
|
this is how FFmpeg is built as well.
|
|
@item Edit @code{zconf.h} and remove its inclusion of @code{unistd.h}. This gets
|
|
erroneously included when building FFmpeg.
|
|
@item Run @code{nmake -f win32/Makefile.msc}.
|
|
@item Move @code{zlib.lib}, @code{zconf.h}, and @code{zlib.h} to somewhere MSVC
|
|
can see.
|
|
@end enumerate
|
|

|
@item FFmpeg has been tested with the following on i686 and x86_64:

@subsection Linking to FFmpeg with Microsoft Visual C++
|
|
|
|
If you plan to link with MSVC-built static libraries, you will need
|
|
to make sure you have @code{Runtime Library} set to
|
|
@code{Multi-threaded (/MT)} in your project's settings.
|
|
|
|
You will need to define @code{inline} to something MSVC understands:
|
|
@example
|
|
#define inline __inline
|
|
@end example
|
|
|
|
Also note, that as stated in @strong{Microsoft Visual C++}, you will need
|
|
an MSVC-compatible @uref{http://code.google.com/p/msinttypes/, inttypes.h}.
|
|
|
|
If you plan on using import libraries created by dlltool, you must
|
|
set @code{References} to @code{No (/OPT:NOREF)} under the linker optimization
|
|
settings, otherwise the resulting binaries will fail during runtime.
|
|
This is not required when using import libraries generated by @code{lib.exe}.
|
|
This issue is reported upstream at
|
|
@url{http://sourceware.org/bugzilla/show_bug.cgi?id=12633}.
|
|
|
|
To create import libraries that work with the @code{/OPT:REF} option
|
|
(which is enabled by default in Release mode), follow these steps:
|
|
|
|
@enumerate
|
|
|
|
@item Open the @emph{Visual Studio Command Prompt}.
|
|
|
|
Alternatively, in a normal command line prompt, call @file{vcvars32.bat}
|
|
which sets up the environment variables for the Visual C++ tools
|
|
(the standard location for this file is something like
|
|
@file{C:\Program Files (x86_\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat}).
|
|
|
|
@item Enter the @file{bin} directory where the created LIB and DLL files
|
|
are stored.
|
|
|
|
@item Generate new import libraries with @command{lib.exe}:
|
|
|
|
@example
|
|
lib /machine:i386 /def:..\lib\foo-version.def /out:foo.lib
|
|
@end example
|
|
|
|
Replace @code{foo-version} and @code{foo} with the respective library names.
|
|
|
|
@end enumerate

@anchor{Cross compilation for Windows with Linux}
|
|
@section Cross compilation for Windows with Linux
|
|
|
|
You must use the MinGW cross compilation tools available at
|
|
@url{http://www.mingw.org/}.
|
|
|
|
Then configure FFmpeg with the following options:
|
|
@example
|
|
./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
|
|
@end example
|
|
(you can change the cross-prefix according to the prefix chosen for the
|
|
MinGW tools).
|
|
|
|
Then you can easily test FFmpeg with @uref{http://www.winehq.com/, Wine}.
|
|
|
|
@section Compilation under Cygwin
|
|
|
|
Please use Cygwin 1.7.x as the obsolete 1.5.x Cygwin versions lack
|
|
llrint() in its C library.
|
|
|
|
Install your Cygwin with all the "Base" packages, plus the
|
|
following "Devel" ones:
|
|
@example
|
|
binutils, gcc4-core, make, git, mingw-runtime, texinfo
|
|
@end example
|
|
|
|
In order to run FATE you will also need the following "Utils" packages:
|
|
@example
|
|
diffutils
|
|
@end example
|
|
|
|
If you want to build FFmpeg with additional libraries, download Cygwin
|
|
"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
|
|
@example
|
|
libogg-devel, libvorbis-devel
|
|
@end example
|
|
|
|
These library packages are only available from
|
|
@uref{http://sourceware.org/cygwinports/, Cygwin Ports}:
|
|
|
|
@example
|
|
yasm, libSDL-devel, libgsm-devel, libmp3lame-devel,
|
|
libschroedinger1.0-devel, speex-devel, libtheora-devel, libxvidcore-devel
|
|
@end example
|
|
|
|
The recommendation for x264 is to build it from source, as it evolves too
|
|
quickly for Cygwin Ports to be up to date.
|
|
|
|
@section Crosscompilation for Windows under Cygwin
|
|
|
|
With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
|
|
|
|
Just install your Cygwin as explained before, plus these additional
|
|
"Devel" packages:
|
|
@example
|
|
gcc-mingw-core, mingw-runtime, mingw-zlib
|
|
@end example
|
|
|
|
and add some special flags to your configure invocation.
|
|
|
|
For a static build run
|
|
@example
|
|
./configure --target-os=mingw32 --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
|
|
@end example
|
|
|
|
and for a build with shared libraries
|
|
@example
|
|
./configure --target-os=mingw32 --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
|
|
@end example
|
|
|
|
@bye
