15
explicitly requested by passing the appropriate flags to @file{./configure}.

Some parts of FFmpeg cannot be built with version 2.15 of the GNU
759
assembler which is still provided by a few AMD64 distributions. To
760
make sure your compiler really uses the required version of gas
761
after a binutils upgrade, run:
762
763
@example
764
$(gcc -print-prog-name=as) --version
765
@end example
766
767
If not, then you should install a different compiler that has no
768
hard-coded path to gas. In the worst case pass @code{--disable-asm}
769
to configure.

@subsection BSD
772 d0e1cd3d Diego Biurrun
773
BSD make will not build FFmpeg, you need to install and use GNU Make
774
(@file{gmake}).

776 bee694bc Michael Kostylev
@subsubsection FreeBSD
777 54dab567 Diego Biurrun
778
FreeBSD will not compile out-of-the-box due to broken system headers.
779
Passing @code{--extra-cflags=-D__BSD_VISIBLE} to configure will work
780
around the problem. This may have unexpected sideeffects, so use it at
781
your own risk. If you care about FreeBSD, please make an attempt at
782
getting the system headers fixed.

@subsection (Open)Solaris
785 3fd427cd Diego Biurrun
786
GNU Make is required to build FFmpeg, so you have to invoke (@file{gmake}),
787 e69decae Michael Kostylev
standard Solaris Make will not work. When building with a non-c99 front-end
788 ee945547 Diego Biurrun
(gcc, generic suncc) add either @code{--extra-libs=/usr/lib/values-xpg6.o}
789 e69decae Michael Kostylev
or @code{--extra-libs=/usr/lib/64/values-xpg6.o} to the configure options
790
since the libc is not c99-compliant by default. The probes performed by
791
configure may raise an exception leading to the death of configure itself
792
due to a bug in the system shell. Simply invoke a different shell such as
793
bash directly to work around this:
794
795
@example
796
bash ./configure
797
@end example

801
MacOS X on PowerPC or ARM (iPhone) requires a preprocessor from
802
@url{http://github.com/yuvi/gas-preprocessor} to build the optimized
803 06a2ba23 Diego Biurrun
assembler functions. Just download the Perl script and put it somewhere
804
in your PATH, FFmpeg's configure will pick it up automatically.

@subsection Native Windows compilation
813
814 c1989552 Ramiro Polla
FFmpeg can be built to run natively on Windows using the MinGW tools. Install
815 126cadc7 Ramiro Polla
the latest versions of MSYS and MinGW from @url{http://www.mingw.org/}.
816
You can find detailed installation
817 d0e1cd3d Diego Biurrun
instructions in the download section and the FAQ.
818
819 126cadc7 Ramiro Polla
FFmpeg does not build out-of-the-box with the packages the automated MinGW
820
installer provides. It also requires coreutils to be installed and many other
821
packages updated to the latest version. The minimum version for some packages
822
are listed below:
823
824
@itemize
825
@item bash 3.1
826
@item msys-make 3.81-2 (note: not mingw32-make)
827 2014b51c Ramiro Polla

@item mingw-runtime 3.15
829
@end itemize
830
831 44be8d42 Ramiro Polla
FFmpeg automatically passes @code{-fno-common} to the compiler to work around
832 0f898714 Diego Biurrun
a GCC bug (see @url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216}).
833
834 c1989552 Ramiro Polla
Within the MSYS shell, configure and make with:
835 d0e1cd3d Diego Biurrun
836 c1989552 Ramiro Polla
@example
837 1a04d4c7 Ramiro Polla
./configure --enable-memalign-hack
838 c1989552 Ramiro Polla
make
839
make install
840
@end example
841 d0e1cd3d Diego Biurrun
842 c1989552 Ramiro Polla
This will install @file{ffmpeg.exe} along with many other development files
843
to @file{/usr/local}. You may specify another install path using the
844
@code{--prefix} option in @file{configure}.

@item Building natively using MSYS can be sped up by disabling implicit rules
851
in the Makefile by calling @code{make -r} instead of plain @code{make}. This
852
speed up is close to non-existent for normal one-off builds and is only
853
noticeable when running make for a second time (for example in
854
@code{make install}).
855
856 c1989552 Ramiro Polla
@item In order to compile FFplay, you must have the MinGW development library
857
of SDL. Get it from @url{http://www.libsdl.org}.
858
Edit the @file{bin/sdl-config} script so that it points to the correct prefix
859
where SDL was installed. Verify that @file{sdl-config} can be launched from
860
the MSYS command line.
861 d0e1cd3d Diego Biurrun
862
@item By using @code{./configure --enable-shared} when configuring FFmpeg,

@subsection Microsoft Visual C++ compatibility
868 d0e1cd3d Diego Biurrun
869 c1989552 Ramiro Polla
As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
870
want to use the libav* libraries in your own applications, you can still
871
compile those applications using MSVC++. But the libav* libraries you link
872
to @emph{must} be built with MinGW. However, you will not be able to debug
873
inside the libav* libraries, since MSVC++ does not recognize the debug
874
symbols generated by GCC.
875
We strongly recommend you to move over from MSVC++ to MinGW tools.
876 d0e1cd3d Diego Biurrun
877 c1989552 Ramiro Polla
This description of how to use the FFmpeg libraries with MSVC++ is based on
878
Microsoft Visual C++ 2005 Express Edition. If you have a different version,
879
you might have to modify the procedures slightly.
880 d0e1cd3d Diego Biurrun
881 c1989552 Ramiro Polla
@subsubsection Using static libraries
882 d0e1cd3d Diego Biurrun
883 c1989552 Ramiro Polla
Assuming you have just built and installed FFmpeg in @file{/usr/local}.
884 d0e1cd3d Diego Biurrun
885
@enumerate
886
887
@item Create a new console application ("File / New / Project") and then
888
select "Win32 Console Application". On the appropriate page of the
889
Application Wizard, uncheck the "Precompiled headers" option.
890
891
@item Write the source code for your application, or, for testing, just
892
copy the code from an existing sample application into the source file
893 c1989552 Ramiro Polla
that MSVC++ has already created for you. For example, you can copy
894 d95a0c67 Diego Biurrun
@file{libavformat/output-example.c} from the FFmpeg distribution.
895 d0e1cd3d Diego Biurrun
896
@item Open the "Project / Properties" dialog box. In the "Configuration"
897
combo box, select "All Configurations" so that the changes you make will
898
affect both debug and release builds. In the tree view on the left hand
899
side, select "C/C++ / General", then edit the "Additional Include
900 c1989552 Ramiro Polla
Directories" setting to contain the path where the FFmpeg includes were
901
installed (i.e. @file{c:\msys\1.0\local\include}).
902 f010d377 Ramiro Polla
Do not add MinGW's include directory here, or the include files will
903
conflict with MSVC's.
904 c1989552 Ramiro Polla
905
@item Still in the "Project / Properties" dialog box, select
906
"Linker / General" from the tree view and edit the
907
"Additional Library Directories" setting to contain the @file{lib}
908
directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
909
the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
910
and the directory where MinGW's GCC libs are installed
911
(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
912
"Linker / Input" from the tree view, and add the files @file{libavformat.a},
913
@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
914
@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
915
to the end of "Additional Dependencies".
916 d0e1cd3d Diego Biurrun
917
@item Now, select "C/C++ / Code Generation" from the tree view. Select
918
"Debug" in the "Configuration" combo box. Make sure that "Runtime
919
Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
920
the "Configuration" combo box and make sure that "Runtime Library" is
921
set to "Multi-threaded DLL".
922
923 c1989552 Ramiro Polla
@item Click "OK" to close the "Project / Properties" dialog box.
924
925
@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
926
Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
927
and install it in MSVC++'s include directory
928
(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
929
930
@item MSVC++ also does not understand the @code{inline} keyword used by
931
FFmpeg, so you must add this line before @code{#include}ing libav*:
932
@example
933
#define inline _inline
934
@end example
935
936
@item Build your application, everything should work.
937
938
@end enumerate
939
940
@subsubsection Using shared libraries
941
942
This is how to create DLL and LIB files that are compatible with MSVC++:
943
944
@enumerate
945
946
@item Add a call to @file{vcvars32.bat} (which sets up the environment
947
variables for the Visual C++ tools) as the first line of @file{msys.bat}.
948
The standard location for @file{vcvars32.bat} is
949
@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
950
and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
951
If this corresponds to your setup, add the following line as the first line
952
of @file{msys.bat}:
953
954
@example
955
call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
956
@end example
957
958
Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
959
and run @file{c:\msys\1.0\msys.bat} from there.
960
961
@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
962
from @file{Microsoft (R) Library Manager}, this means your environment
963
variables are set up correctly, the @file{Microsoft (R) Library Manager}
964
is on the path and will be used by FFmpeg to create
965
MSVC++-compatible import libraries.
966
967
@item Build FFmpeg with
968
969
@example
970
./configure --enable-shared --enable-memalign-hack
971
make
972
make install
973
@end example
974
975
Your install path (@file{/usr/local/} by default) should now have the
976
necessary DLL and LIB files under the @file{bin} directory.
977 d0e1cd3d Diego Biurrun
978
@end enumerate
979
980 c1989552 Ramiro Polla
To use those files with MSVC++, do the same as you would do with
981
the static libraries, as described above. But in Step 4,
982
you should only need to add the directory where the LIB files are installed
983
(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
984 bc3836a1 Ramiro Polla
installed in the @file{bin} directory. And instead of adding the static
985
libraries (@file{libxxx.a} files) you should add the MSVC import libraries
986
(@file{avcodec.lib}, @file{avformat.lib}, @file{avcore.lib}, and
987
@file{avutil.lib}). Note that you should not use the GCC import
988
libraries (@file{libxxx.dll.a} files), as these will give you undefined
989
reference errors. There should be no need for @file{libmingwex.a},
990 c1989552 Ramiro Polla
@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
991
statically linked into the DLLs. The @file{bin} directory contains a bunch
992
of DLL files, but the ones that are actually used to run your application
993
are the ones with a major version number in their filenames
994
(i.e. @file{avcodec-51.dll}).
995
996 e16c1569 Ramiro Polla
FFmpeg headers do not declare global data for Windows DLLs through the usual
997
dllexport/dllimport interface. Such data will be exported properly while
998
building, but to use them in your MSVC++ code you will have to edit the
999
appropriate headers and mark the data as dllimport. For example, in
1000
libavutil/pixdesc.h you should have:
1001
@example
1002
extern __declspec(dllimport) const AVPixFmtDescriptor av_pix_fmt_descriptors[];
1003
@end example
1004
1005 d0e1cd3d Diego Biurrun
@subsection Cross compilation for Windows with Linux
1006
1007
You must use the MinGW cross compilation tools available at
1008
@url{http://www.mingw.org/}.
1009
1010
Then configure FFmpeg with the following options:
1011
@example
1012
./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
1013
@end example
1014
(you can change the cross-prefix according to the prefix chosen for the
1015
MinGW tools).
1016
1017
Then you can easily test FFmpeg with Wine
1018
(@url{http://www.winehq.com/}).
1019
1020
@subsection Compilation under Cygwin
1021
1022 2f821b03 Víctor Paesa
Please use Cygwin 1.7.x as the obsolete 1.5.x Cygwin versions lack
1023
llrint() in its C library.
1024 d0e1cd3d Diego Biurrun
1025 2f821b03 Víctor Paesa
Install your Cygwin with all the "Base" packages, plus the
1026 d0e1cd3d Diego Biurrun
following "Devel" ones:
1027
@example
1028 2f821b03 Víctor Paesa
binutils, gcc4-core, make, subversion, mingw-runtime, texi2html
1029 71ecc16b Ramiro Polla
@end example
1030
1031
And the following "Utils" one:
1032
@example
1033
diffutils
1034 d0e1cd3d Diego Biurrun
@end example
1035
1036
Then run
1037
1038
@example
1039 2f821b03 Víctor Paesa
./configure --enable-static --disable-shared
1040 d0e1cd3d Diego Biurrun
@end example
1041
1042 2f821b03 Víctor Paesa
to make a static build.
1043
1044
The current @code{gcc4-core} package is buggy and needs this flag to build
1045
shared libraries:
1046 d0e1cd3d Diego Biurrun
1047
@example
1048 2f821b03 Víctor Paesa
./configure --enable-shared --disable-static --extra-cflags=-fno-reorder-functions
1049 d0e1cd3d Diego Biurrun
@end example
1050
1051
If you want to build FFmpeg with additional libraries, download Cygwin
1052 5dd9799d Víctor Paesa
"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
1053
@example
1054
libogg-devel, libvorbis-devel
1055
@end example
1056
1057
These library packages are only available from Cygwin Ports
1058 be8497b0 Víctor Paesa
(@url{http://sourceware.org/cygwinports/}) :
1059 5dd9799d Víctor Paesa
1060
@example
1061 6a74b127 Måns Rullgård
yasm, libSDL-devel, libdirac-devel, libfaac-devel, libgsm-devel,
1062 5dd9799d Víctor Paesa
libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
1063
libxvidcore-devel
1064
@end example
1065
1066
The recommendation for libnut and x264 is to build them from source by
1067
yourself, as they evolve too quickly for Cygwin Ports to be up to date.
1068 d0e1cd3d Diego Biurrun
1069 cdf51395 Víctor Paesa
Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
1070
of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
1071
1072 d0e1cd3d Diego Biurrun
@subsection Crosscompilation for Windows under Cygwin
1073
1074
With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
1075
1076
Just install your Cygwin as explained before, plus these additional
1077
"Devel" packages:
1078
@example
1079
gcc-mingw-core, mingw-runtime, mingw-zlib
1080
@end example
1081
1082
and add some special flags to your configure invocation.
1083
1084
For a static build run
1085
@example
1086
./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1087
@end example
1088
1089
and for a build with shared libraries
1090
@example
1091
./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1092
