@chapter external libraries
13

    
14
FFmpeg can be hooked up with a number of external libraries to add support
15
for more formats. None of them are used by default, their use has to be
16
explicitly requested by passing the appropriate flags to @file{./configure}.
17

    
18
@section OpenCORE AMR
19

    
20
FFmpeg can make use of the OpenCORE libraries for AMR-NB
21
decoding/encoding and AMR-WB decoding.
22

    
23
Go to @url{http://sourceforge.net/projects/opencore-amr/} and follow the instructions for
24
installing the libraries. Then pass @code{--enable-libopencore-amrnb} and/or
25
@code{--enable-libopencore-amrwb} to configure to enable the libraries.
26

    
27
Note that OpenCORE is under the Apache License 2.0 (see
28
@url{http://www.apache.org/licenses/LICENSE-2.0} for details), which is
29
incompatible with the LGPL version 2.1 and GPL version 2. You have to
30
upgrade FFmpeg's license to LGPL version 3 (or if you have enabled
31
GPL components, GPL version 3) to use it.

746
Using a cross-compiler is preferred for various reasons.
747

    
748
@subsection DJGPP
749

    
750
FFmpeg cannot be compiled because of broken system headers, add
751
@code{--extra-cflags=-U__STRICT_ANSI__} to the configure options as a
752
workaround.
753

    
754
@section OS/2

756
For information about compiling FFmpeg on OS/2 see
757
@url{http://www.edm2.com/index.php/FFmpeg}.
758

    
759
@section Unix-like
760

    
761
Some parts of FFmpeg cannot be built with version 2.15 of the GNU
762
assembler which is still provided by a few AMD64 distributions. To
763
make sure your compiler really uses the required version of gas
764
after a binutils upgrade, run:
765

    
766
@example
767
$(gcc -print-prog-name=as) --version
768
@end example
769

    
770
If not, then you should install a different compiler that has no
771
hard-coded path to gas. In the worst case pass @code{--disable-asm}
772
to configure.
773

    
774
@subsection BSD
775

    
776
BSD make will not build FFmpeg, you need to install and use GNU Make
777
(@file{gmake}).
778

    
779
@subsubsection FreeBSD
780

    
781
FreeBSD will not compile out-of-the-box due to broken system headers.
782
Passing @code{--extra-cflags=-D__BSD_VISIBLE} to configure will work
783
around the problem. This may have unexpected sideeffects, so use it at
784
your own risk. If you care about FreeBSD, please make an attempt at
785
getting the system headers fixed.
786

    
787
@subsection (Open)Solaris
788

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

    
798
@example
799
bash ./configure
800
@end example
801

    
802
@subsection Darwin (MacOS X, iPhone)
803

    
804
MacOS X on PowerPC or ARM (iPhone) requires a preprocessor from
805
@url{http://github.com/yuvi/gas-preprocessor} to build the optimized
806
assembler functions. Just download the Perl script and put it somewhere
807
in your PATH, FFmpeg's configure will pick it up automatically.
808

    
809
@section Windows
810

    
811
To get help and instructions for building FFmpeg under Windows, check out
812
the FFmpeg Windows Help Forum at
813
@url{http://ffmpeg.arrozcru.org/}.
814

    
815
@subsection Native Windows compilation
816

    
817
FFmpeg can be built to run natively on Windows using the MinGW tools. Install
818
the latest versions of MSYS and MinGW from @url{http://www.mingw.org/}.
819
You can find detailed installation
820
instructions in the download section and the FAQ.
821

    
822
FFmpeg does not build out-of-the-box with the packages the automated MinGW
823
installer provides. It also requires coreutils to be installed and many other
824
packages updated to the latest version. The minimum version for some packages
825
are listed below:
826

    
827
@itemize
828
@item bash 3.1
829
@item msys-make 3.81-2 (note: not mingw32-make)
830
@item w32api 3.13
831
@item mingw-runtime 3.15
832
@end itemize
833

    
834
FFmpeg automatically passes @code{-fno-common} to the compiler to work around
835
a GCC bug (see @url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216}).
836

    
837
Within the MSYS shell, configure and make with:
838

    
839
@example
840
./configure --enable-memalign-hack
841
make
842
make install
843
@end example
844

    
845
This will install @file{ffmpeg.exe} along with many other development files
846
to @file{/usr/local}. You may specify another install path using the
847
@code{--prefix} option in @file{configure}.
848

    
849
Notes:
850

    
851
@itemize
852

    
853
@item Building natively using MSYS can be sped up by disabling implicit rules
854
in the Makefile by calling @code{make -r} instead of plain @code{make}. This
855
speed up is close to non-existent for normal one-off builds and is only
856
noticeable when running make for a second time (for example in
857
@code{make install}).
858

    
859
@item In order to compile FFplay, you must have the MinGW development library
860
of SDL. Get it from @url{http://www.libsdl.org}.
861
Edit the @file{bin/sdl-config} script so that it points to the correct prefix
862
where SDL was installed. Verify that @file{sdl-config} can be launched from
863
the MSYS command line.
864

    
865
@item By using @code{./configure --enable-shared} when configuring FFmpeg,
866
you can build libavutil, libavcodec and libavformat as DLLs.
867

    
868
@end itemize
869

    
870
@subsection Microsoft Visual C++ compatibility
871

    
872
As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
873
want to use the libav* libraries in your own applications, you can still
874
compile those applications using MSVC++. But the libav* libraries you link
875
to @emph{must} be built with MinGW. However, you will not be able to debug
876
inside the libav* libraries, since MSVC++ does not recognize the debug
877
symbols generated by GCC.
878
We strongly recommend you to move over from MSVC++ to MinGW tools.
879

    
880
This description of how to use the FFmpeg libraries with MSVC++ is based on
881
Microsoft Visual C++ 2005 Express Edition. If you have a different version,
882
you might have to modify the procedures slightly.
883

    
884
@subsubsection Using static libraries
885

    
886
Assuming you have just built and installed FFmpeg in @file{/usr/local}.
887

    
888
@enumerate
889

    
890
@item Create a new console application ("File / New / Project") and then
891
select "Win32 Console Application". On the appropriate page of the
892
Application Wizard, uncheck the "Precompiled headers" option.
893

    
894
@item Write the source code for your application, or, for testing, just
895
copy the code from an existing sample application into the source file
896
that MSVC++ has already created for you. For example, you can copy
897
@file{libavformat/output-example.c} from the FFmpeg distribution.
898

    
899
@item Open the "Project / Properties" dialog box. In the "Configuration"
900
combo box, select "All Configurations" so that the changes you make will
901
affect both debug and release builds. In the tree view on the left hand
902
side, select "C/C++ / General", then edit the "Additional Include
903
Directories" setting to contain the path where the FFmpeg includes were
904
installed (i.e. @file{c:\msys\1.0\local\include}).
905
Do not add MinGW's include directory here, or the include files will
906
conflict with MSVC's.
907

    
908
@item Still in the "Project / Properties" dialog box, select
909
"Linker / General" from the tree view and edit the
910
"Additional Library Directories" setting to contain the @file{lib}
911
directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
912
the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
913
and the directory where MinGW's GCC libs are installed
914
(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
915
"Linker / Input" from the tree view, and add the files @file{libavformat.a},
916
@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
917
@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
918
to the end of "Additional Dependencies".
919

    
920
@item Now, select "C/C++ / Code Generation" from the tree view. Select
921
"Debug" in the "Configuration" combo box. Make sure that "Runtime
922
Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
923
the "Configuration" combo box and make sure that "Runtime Library" is
924
set to "Multi-threaded DLL".
925

    
926
@item Click "OK" to close the "Project / Properties" dialog box.
927

    
928
@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
929
Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
930
and install it in MSVC++'s include directory
931
(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
932

    
933
@item MSVC++ also does not understand the @code{inline} keyword used by
934
FFmpeg, so you must add this line before @code{#include}ing libav*:
935
@example
936
#define inline _inline
937
@end example
938

    
939
@item Build your application, everything should work.
940

    
941
@end enumerate
942

    
943
@subsubsection Using shared libraries
944

    
945
This is how to create DLL and LIB files that are compatible with MSVC++:
946

    
947
@enumerate
948

    
949
@item Add a call to @file{vcvars32.bat} (which sets up the environment
950
variables for the Visual C++ tools) as the first line of @file{msys.bat}.
951
The standard location for @file{vcvars32.bat} is
952
@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
953
and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
954
If this corresponds to your setup, add the following line as the first line
955
of @file{msys.bat}:
956

    
957
@example
958
call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
959
@end example
960

    
961
Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
962
and run @file{c:\msys\1.0\msys.bat} from there.
963

    
964
@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
965
from @file{Microsoft (R) Library Manager}, this means your environment
966
variables are set up correctly, the @file{Microsoft (R) Library Manager}
967
is on the path and will be used by FFmpeg to create
968
MSVC++-compatible import libraries.
969

    
970
@item Build FFmpeg with
971

    
972
@example
973
./configure --enable-shared --enable-memalign-hack
974
make
975
make install
976
@end example
977

    
978
Your install path (@file{/usr/local/} by default) should now have the
979
necessary DLL and LIB files under the @file{bin} directory.
980

    
981
@end enumerate
982

    
983
To use those files with MSVC++, do the same as you would do with
984
the static libraries, as described above. But in Step 4,
985
you should only need to add the directory where the LIB files are installed
986
(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
987
installed in the @file{bin} directory. And instead of adding the static
988
libraries (@file{libxxx.a} files) you should add the MSVC import libraries
989
(@file{avcodec.lib}, @file{avformat.lib}, @file{avcore.lib}, and
990
@file{avutil.lib}). Note that you should not use the GCC import
991
libraries (@file{libxxx.dll.a} files), as these will give you undefined
992
reference errors. There should be no need for @file{libmingwex.a},
993
@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
994
statically linked into the DLLs. The @file{bin} directory contains a bunch
995
of DLL files, but the ones that are actually used to run your application
996
are the ones with a major version number in their filenames
997
(i.e. @file{avcodec-51.dll}).
998

    
999
FFmpeg headers do not declare global data for Windows DLLs through the usual
1000
dllexport/dllimport interface. Such data will be exported properly while
1001
building, but to use them in your MSVC++ code you will have to edit the
1002
appropriate headers and mark the data as dllimport. For example, in
1003
libavutil/pixdesc.h you should have:
1004
@example
1005
extern __declspec(dllimport) const AVPixFmtDescriptor av_pix_fmt_descriptors[];
1006
@end example
1007

    
1008
@subsection Cross compilation for Windows with Linux
1009

    
1010
You must use the MinGW cross compilation tools available at
1011
@url{http://www.mingw.org/}.
1012

    
1013
Then configure FFmpeg with the following options:
1014
@example
1015
./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
1016
@end example
1017
(you can change the cross-prefix according to the prefix chosen for the
1018
MinGW tools).
1019

    
1020
Then you can easily test FFmpeg with Wine
1021
(@url{http://www.winehq.com/}).
1022

    
1023
@subsection Compilation under Cygwin
1024

    
1025
Please use Cygwin 1.7.x as the obsolete 1.5.x Cygwin versions lack
1026
llrint() in its C library.
1027

    
1028
Install your Cygwin with all the "Base" packages, plus the
1029
following "Devel" ones:
1030
@example
1031
binutils, gcc4-core, make, subversion, mingw-runtime, texi2html
1032
@end example
1033

    
1034
And the following "Utils" one:
1035
@example
1036
diffutils
1037
@end example
1038

    
1039
Then run
1040

    
1041
@example
1042
./configure --enable-static --disable-shared
1043
@end example
1044

    
1045
to make a static build.
1046

    
1047
The current @code{gcc4-core} package is buggy and needs this flag to build
1048
shared libraries:
1049

    
1050
@example
1051
./configure --enable-shared --disable-static --extra-cflags=-fno-reorder-functions
1052
@end example
1053

    
1054
If you want to build FFmpeg with additional libraries, download Cygwin
1055
"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
1056
@example
1057
libogg-devel, libvorbis-devel
1058
@end example
1059

    
1060
These library packages are only available from Cygwin Ports
1061
(@url{http://sourceware.org/cygwinports/}) :
1062

    
1063
@example
1064
yasm, libSDL-devel, libdirac-devel, libfaac-devel, libgsm-devel,
1065
libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
1066
libxvidcore-devel
1067
@end example
1068

    
1069
The recommendation for libnut and x264 is to build them from source by
1070
yourself, as they evolve too quickly for Cygwin Ports to be up to date.
1071

    
1072
Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
1073
of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
1074

    
1075
@subsection Crosscompilation for Windows under Cygwin
1076

    
1077
With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
1078

    
1079
Just install your Cygwin as explained before, plus these additional
1080
"Devel" packages:
1081
@example
1082
gcc-mingw-core, mingw-runtime, mingw-zlib
1083
@end example
1084

    
1085
and add some special flags to your configure invocation.
1086

    
1087
For a static build run
1088
@example
1089
./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1090
@end example
1091

    
1092
and for a build with shared libraries
1093
@example
1094
./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1095
@end example
1096
