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
760
assembler which is still provided by a few AMD64 distributions. To
761
make sure your compiler really uses the required version of gas
762
after a binutils upgrade, run:
763
764
@example
765
$(gcc -print-prog-name=as) --version
766
@end example
767
768
If not, then you should install a different compiler that has no
769
hard-coded path to gas. In the worst case pass @code{--disable-asm}
770
to configure.

standard Solaris Make will not work. When building with a non-c99 front-end
789 ee945547 Diego Biurrun

790 e69decae Michael Kostylev
or @code{--extra-libs=/usr/lib/64/values-xpg6.o} to the configure options
791
since the libc is not c99-compliant by default. The probes performed by
792
configure may raise an exception leading to the death of configure itself
793
due to a bug in the system shell. Simply invoke a different shell such as

As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
871
want to use the libav* libraries in your own applications, you can still
872
compile those applications using MSVC++. But the libav* libraries you link
873
to @emph{must} be built with MinGW. However, you will not be able to debug
874
inside the libav* libraries, since MSVC++ does not recognize the debug
875
symbols generated by GCC.
876
We strongly recommend you to move over from MSVC++ to MinGW tools.
877 d0e1cd3d Diego Biurrun
878 c1989552 Ramiro Polla
This description of how to use the FFmpeg libraries with MSVC++ is based on
879
Microsoft Visual C++ 2005 Express Edition. If you have a different version,
880
you might have to modify the procedures slightly.

@subsubsection Using static libraries
883 d0e1cd3d Diego Biurrun
884 c1989552 Ramiro Polla
Assuming you have just built and installed FFmpeg in @file{/usr/local}.
885 d0e1cd3d Diego Biurrun
886
@enumerate
887
888
@item Create a new console application ("File / New / Project") and then
889
select "Win32 Console Application". On the appropriate page of the
890
Application Wizard, uncheck the "Precompiled headers" option.
891
892
@item Write the source code for your application, or, for testing, just
893
copy the code from an existing sample application into the source file
894 c1989552 Ramiro Polla
that MSVC++ has already created for you. For example, you can copy
895 d95a0c67 Diego Biurrun
@file{libavformat/output-example.c} from the FFmpeg distribution.
896 d0e1cd3d Diego Biurrun
897
@item Open the "Project / Properties" dialog box. In the "Configuration"
898
combo box, select "All Configurations" so that the changes you make will
899
affect both debug and release builds. In the tree view on the left hand
900
side, select "C/C++ / General", then edit the "Additional Include
901 c1989552 Ramiro Polla
Directories" setting to contain the path where the FFmpeg includes were
902
installed (i.e. @file{c:\msys\1.0\local\include}).
903 f010d377 Ramiro Polla
Do not add MinGW's include directory here, or the include files will
904
conflict with MSVC's.
905 c1989552 Ramiro Polla
906
@item Still in the "Project / Properties" dialog box, select
907
"Linker / General" from the tree view and edit the
908
"Additional Library Directories" setting to contain the @file{lib}
909
directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
910
the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
911
and the directory where MinGW's GCC libs are installed
912
(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
913
"Linker / Input" from the tree view, and add the files @file{libavformat.a},
914
@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
915
@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
916
to the end of "Additional Dependencies".
917 d0e1cd3d Diego Biurrun
918
@item Now, select "C/C++ / Code Generation" from the tree view. Select
919
"Debug" in the "Configuration" combo box. Make sure that "Runtime
920
Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
921
the "Configuration" combo box and make sure that "Runtime Library" is
922
set to "Multi-threaded DLL".
923
924 c1989552 Ramiro Polla
@item Click "OK" to close the "Project / Properties" dialog box.
925
926
@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
927
Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
928
and install it in MSVC++'s include directory
929
(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
930
931
@item MSVC++ also does not understand the @code{inline} keyword used by
932
FFmpeg, so you must add this line before @code{#include}ing libav*:
933
@example
934
#define inline _inline
935
@end example
936
937
@item Build your application, everything should work.
938
939
@end enumerate
940
941
@subsubsection Using shared libraries
942
943
This is how to create DLL and LIB files that are compatible with MSVC++:
944
945
@enumerate
946
947
@item Add a call to @file{vcvars32.bat} (which sets up the environment
948
variables for the Visual C++ tools) as the first line of @file{msys.bat}.
949
The standard location for @file{vcvars32.bat} is
950
@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
951
and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
952
If this corresponds to your setup, add the following line as the first line
953
of @file{msys.bat}:
954
955
@example
956
call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
957
@end example
958
959
Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
960
and run @file{c:\msys\1.0\msys.bat} from there.
961
962
@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
963
from @file{Microsoft (R) Library Manager}, this means your environment
964
variables are set up correctly, the @file{Microsoft (R) Library Manager}
965
is on the path and will be used by FFmpeg to create
966
MSVC++-compatible import libraries.
967
968
@item Build FFmpeg with
969
970
@example
971
./configure --enable-shared --enable-memalign-hack
972
make
973
make install
974
@end example
975
976
Your install path (@file{/usr/local/} by default) should now have the
977
necessary DLL and LIB files under the @file{bin} directory.
978 d0e1cd3d Diego Biurrun
979
@end enumerate
980
981 c1989552 Ramiro Polla
To use those files with MSVC++, do the same as you would do with
982
the static libraries, as described above. But in Step 4,
983
you should only need to add the directory where the LIB files are installed
984
(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
985 bc3836a1 Ramiro Polla
installed in the @file{bin} directory. And instead of adding the static
986
libraries (@file{libxxx.a} files) you should add the MSVC import libraries
987
(@file{avcodec.lib}, @file{avformat.lib}, @file{avcore.lib}, and
988
@file{avutil.lib}). Note that you should not use the GCC import
989
libraries (@file{libxxx.dll.a} files), as these will give you undefined
990
reference errors. There should be no need for @file{libmingwex.a},
991 c1989552 Ramiro Polla
@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
992
statically linked into the DLLs. The @file{bin} directory contains a bunch
993
of DLL files, but the ones that are actually used to run your application
994
are the ones with a major version number in their filenames
995
(i.e. @file{avcodec-51.dll}).
996
997 e16c1569 Ramiro Polla
FFmpeg headers do not declare global data for Windows DLLs through the usual
998
dllexport/dllimport interface. Such data will be exported properly while
999
building, but to use them in your MSVC++ code you will have to edit the
1000
appropriate headers and mark the data as dllimport. For example, in
1001
libavutil/pixdesc.h you should have:
1002
@example
1003
extern __declspec(dllimport) const AVPixFmtDescriptor av_pix_fmt_descriptors[];
1004
@end example
1005
1006 d0e1cd3d Diego Biurrun
@subsection Cross compilation for Windows with Linux
1007
1008
You must use the MinGW cross compilation tools available at
1009
@url{http://www.mingw.org/}.
1010
1011
Then configure FFmpeg with the following options:
1012
@example
1013
./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
1014
@end example
1015
(you can change the cross-prefix according to the prefix chosen for the
1016
MinGW tools).
1017
1018
Then you can easily test FFmpeg with Wine
1019
(@url{http://www.winehq.com/}).

@subsection Compilation under Cygwin
1022

1024
llrint() in its C library.
1025 d0e1cd3d Diego Biurrun
1026 2f821b03 Víctor Paesa
Install your Cygwin with all the "Base" packages, plus the

following "Devel" ones:
1028
@example
1029 2f821b03 Víctor Paesa
binutils, gcc4-core, make, subversion, mingw-runtime, texi2html
1030 71ecc16b Ramiro Polla
@end example

1032
And the following "Utils" one:
1033
@example
1034
diffutils
1035 d0e1cd3d Diego Biurrun
@end example
1036
1037
Then run
1038
1039
@example
1040 2f821b03 Víctor Paesa
./configure --enable-static --disable-shared
1041 d0e1cd3d Diego Biurrun
@end example
1042
1043 2f821b03 Víctor Paesa
to make a static build.
1044
1045
The current @code{gcc4-core} package is buggy and needs this flag to build
1046
shared libraries:
1047 d0e1cd3d Diego Biurrun
1048
@example

./configure --enable-shared --disable-static --extra-cflags=-fno-reorder-functions
1050 d0e1cd3d Diego Biurrun
@end example
1051
1052
If you want to build FFmpeg with additional libraries, download Cygwin
1053 5dd9799d Víctor Paesa
"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
1054
@example
1055
libogg-devel, libvorbis-devel
1056
@end example
1057
1058
These library packages are only available from Cygwin Ports

1064
libxvidcore-devel
1065
@end example
1066
1067
The recommendation for libnut and x264 is to build them from source by
1068
yourself, as they evolve too quickly for Cygwin Ports to be up to date.
1069 d0e1cd3d Diego Biurrun
1070 cdf51395 Víctor Paesa
Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
1071
of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
1072
1073 d0e1cd3d Diego Biurrun
@subsection Crosscompilation for Windows under Cygwin
1074
1075
With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
1076
1077
Just install your Cygwin as explained before, plus these additional
1078
"Devel" packages:
1079
@example
1080
gcc-mingw-core, mingw-runtime, mingw-zlib
1081
@end example
1082
1083
and add some special flags to your configure invocation.
1084
1085
For a static build run
1086
@example
1087
./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1088
@end example

1090
and for a build with shared libraries
1091
@example
1092
./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
