@chapter external libraries
12

    
13
FFmpeg can be hooked up with a number of external libraries to add support
14
for more formats. None of them are used by default, their use has to be
15
explicitly requested by passing the appropriate flags to @file{./configure}.
16

    
17
@section OpenCORE AMR
18

    
19
FFmpeg can make use of the OpenCORE libraries for AMR-NB
20
decoding/encoding and AMR-WB decoding.
21

    
22
Go to @url{http://sourceforge.net/projects/opencore-amr/} and follow the instructions for
23
installing the libraries. Then pass @code{--enable-libopencore-amrnb} and/or
24
@code{--enable-libopencore-amrwb} to configure to enable the libraries.
25

    
26
Note that OpenCORE is under the Apache License 2.0 (see
27
@url{http://www.apache.org/licenses/LICENSE-2.0} for details), which is
28
incompatible with the LGPL version 2.1 and GPL version 2. You have to
29
upgrade FFmpeg's license to LGPL version 3 (or if you have enabled
30
GPL components, GPL version 3) to use it.

730
Using a cross-compiler is preferred for various reasons.
731

    
732
@subsection DJGPP
733

    
734
FFmpeg cannot be compiled because of broken system headers, add
735
@code{--extra-cflags=-U__STRICT_ANSI__} to the configure options as a
736
workaround.
737

    
738
@section OS/2
739

    
740
For information about compiling FFmpeg on OS/2 see
741
@url{http://www.edm2.com/index.php/FFmpeg}.
742

    
743
@section Unix-like
744

    
745
Some parts of FFmpeg cannot be built with version 2.15 of the GNU
746
assembler which is still provided by a few AMD64 distributions. To
747
make sure your compiler really uses the required version of gas
748
after a binutils upgrade, run:
749

    
750
@example
751
$(gcc -print-prog-name=as) --version
752
@end example
753

    
754
If not, then you should install a different compiler that has no
755
hard-coded path to gas. In the worst case pass @code{--disable-asm}
756
to configure.
757

    
758
@subsection BSD
759

    
760
BSD make will not build FFmpeg, you need to install and use GNU Make
761
(@file{gmake}).
762

    
763
@subsubsection FreeBSD
764

    
765
FreeBSD will not compile out-of-the-box due to broken system headers.
766
Passing @code{--extra-cflags=-D__BSD_VISIBLE} to configure will work
767
around the problem. This may have unexpected sideeffects, so use it at
768
your own risk. If you care about FreeBSD, please make an attempt at
769
getting the system headers fixed.
770

    
771
@subsection (Open)Solaris
772

    
773
GNU Make is required to build FFmpeg, so you have to invoke (@file{gmake}),
774
standard Solaris Make will not work. When building with a non-c99 front-end
775
(gcc, generic suncc) add either @code{--extra-libs=/usr/lib/values-xpg6.o}
776
or @code{--extra-libs=/usr/lib/64/values-xpg6.o} to the configure options
777
since the libc is not c99-compliant by default. The probes performed by
778
configure may raise an exception leading to the death of configure itself
779
due to a bug in the system shell. Simply invoke a different shell such as
780
bash directly to work around this:
781

    
782
@example
783
bash ./configure
784
@end example
785

    
786
@section Windows
787

    
788
To get help and instructions for building FFmpeg under Windows, check out
789
the FFmpeg Windows Help Forum at
790
@url{http://ffmpeg.arrozcru.org/}.
791

    
792
@subsection Native Windows compilation
793

    
794
FFmpeg can be built to run natively on Windows using the MinGW tools. Install
795
the latest versions of MSYS and MinGW from @url{http://www.mingw.org/}.
796
You can find detailed installation
797
instructions in the download section and the FAQ.
798

    
799
FFmpeg does not build out-of-the-box with the packages the automated MinGW
800
installer provides. It also requires coreutils to be installed and many other
801
packages updated to the latest version. The minimum version for some packages
802
are listed below:
803

    
804
@itemize
805
@item bash 3.1
806
@item msys-make 3.81-2 (note: not mingw32-make)
807
@item w32api 3.13
808
@item mingw-runtime 3.15
809
@end itemize
810

    
811
FFmpeg automatically passes @code{-fno-common} to the compiler to work around
812
a GCC bug (see @url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216}).
813

    
814
Within the MSYS shell, configure and make with:
815

    
816
@example
817
./configure --enable-memalign-hack
818
make
819
make install
820
@end example
821

    
822
This will install @file{ffmpeg.exe} along with many other development files
823
to @file{/usr/local}. You may specify another install path using the
824
@code{--prefix} option in @file{configure}.
825

    
826
Notes:
827

    
828
@itemize
829

    
830
@item Building natively using MSYS can be sped up by disabling implicit rules
831
in the Makefile by calling @code{make -r} instead of plain @code{make}. This
832
speed up is close to non-existent for normal one-off builds and is only
833
noticeable when running make for a second time (for example in
834
@code{make install}).
835

    
836
@item In order to compile FFplay, you must have the MinGW development library
837
of SDL. Get it from @url{http://www.libsdl.org}.
838
Edit the @file{bin/sdl-config} script so that it points to the correct prefix
839
where SDL was installed. Verify that @file{sdl-config} can be launched from
840
the MSYS command line.
841

    
842
@item By using @code{./configure --enable-shared} when configuring FFmpeg,
843
you can build libavutil, libavcodec and libavformat as DLLs.
844

    
845
@end itemize
846

    
847
@subsection Microsoft Visual C++ compatibility
848

    
849
As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
850
want to use the libav* libraries in your own applications, you can still
851
compile those applications using MSVC++. But the libav* libraries you link
852
to @emph{must} be built with MinGW. However, you will not be able to debug
853
inside the libav* libraries, since MSVC++ does not recognize the debug
854
symbols generated by GCC.
855
We strongly recommend you to move over from MSVC++ to MinGW tools.
856

    
857
This description of how to use the FFmpeg libraries with MSVC++ is based on
858
Microsoft Visual C++ 2005 Express Edition. If you have a different version,
859
you might have to modify the procedures slightly.
860

    
861
@subsubsection Using static libraries
862

    
863
Assuming you have just built and installed FFmpeg in @file{/usr/local}.
864

    
865
@enumerate
866

    
867
@item Create a new console application ("File / New / Project") and then
868
select "Win32 Console Application". On the appropriate page of the
869
Application Wizard, uncheck the "Precompiled headers" option.
870

    
871
@item Write the source code for your application, or, for testing, just
872
copy the code from an existing sample application into the source file
873
that MSVC++ has already created for you. For example, you can copy
874
@file{libavformat/output-example.c} from the FFmpeg distribution.
875

    
876
@item Open the "Project / Properties" dialog box. In the "Configuration"
877
combo box, select "All Configurations" so that the changes you make will
878
affect both debug and release builds. In the tree view on the left hand
879
side, select "C/C++ / General", then edit the "Additional Include
880
Directories" setting to contain the path where the FFmpeg includes were
881
installed (i.e. @file{c:\msys\1.0\local\include}).
882
Do not add MinGW's include directory here, or the include files will
883
conflict with MSVC's.
884

    
885
@item Still in the "Project / Properties" dialog box, select
886
"Linker / General" from the tree view and edit the
887
"Additional Library Directories" setting to contain the @file{lib}
888
directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
889
the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
890
and the directory where MinGW's GCC libs are installed
891
(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
892
"Linker / Input" from the tree view, and add the files @file{libavformat.a},
893
@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
894
@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
895
to the end of "Additional Dependencies".
896

    
897
@item Now, select "C/C++ / Code Generation" from the tree view. Select
898
"Debug" in the "Configuration" combo box. Make sure that "Runtime
899
Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
900
the "Configuration" combo box and make sure that "Runtime Library" is
901
set to "Multi-threaded DLL".
902

    
903
@item Click "OK" to close the "Project / Properties" dialog box.
904

    
905
@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
906
Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
907
and install it in MSVC++'s include directory
908
(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
909

    
910
@item MSVC++ also does not understand the @code{inline} keyword used by
911
FFmpeg, so you must add this line before @code{#include}ing libav*:
912
@example
913
#define inline _inline
914
@end example
915

    
916
@item Build your application, everything should work.
917

    
918
@end enumerate
919

    
920
@subsubsection Using shared libraries
921

    
922
This is how to create DLL and LIB files that are compatible with MSVC++:
923

    
924
@enumerate
925

    
926
@item Add a call to @file{vcvars32.bat} (which sets up the environment
927
variables for the Visual C++ tools) as the first line of @file{msys.bat}.
928
The standard location for @file{vcvars32.bat} is
929
@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
930
and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
931
If this corresponds to your setup, add the following line as the first line
932
of @file{msys.bat}:
933

    
934
@example
935
call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
936
@end example
937

    
938
Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
939
and run @file{c:\msys\1.0\msys.bat} from there.
940

    
941
@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
942
from @file{Microsoft (R) Library Manager}, this means your environment
943
variables are set up correctly, the @file{Microsoft (R) Library Manager}
944
is on the path and will be used by FFmpeg to create
945
MSVC++-compatible import libraries.
946

    
947
@item Build FFmpeg with
948

    
949
@example
950
./configure --enable-shared --enable-memalign-hack
951
make
952
make install
953
@end example
954

    
955
Your install path (@file{/usr/local/} by default) should now have the
956
necessary DLL and LIB files under the @file{bin} directory.
957

    
958
@end enumerate
959

    
960
To use those files with MSVC++, do the same as you would do with
961
the static libraries, as described above. But in Step 4,
962
you should only need to add the directory where the LIB files are installed
963
(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
964
installed in the @file{bin} directory. And instead of adding @file{libxx.a}
965
files, you should add @file{avcodec.lib}, @file{avformat.lib}, and
966
@file{avutil.lib}. There should be no need for @file{libmingwex.a},
967
@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
968
statically linked into the DLLs. The @file{bin} directory contains a bunch
969
of DLL files, but the ones that are actually used to run your application
970
are the ones with a major version number in their filenames
971
(i.e. @file{avcodec-51.dll}).
972

    
973
@subsection Cross compilation for Windows with Linux
974

    
975
You must use the MinGW cross compilation tools available at
976
@url{http://www.mingw.org/}.
977

    
978
Then configure FFmpeg with the following options:
979
@example
980
./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
981
@end example
982
(you can change the cross-prefix according to the prefix chosen for the
983
MinGW tools).
984

    
985
Then you can easily test FFmpeg with Wine
986
(@url{http://www.winehq.com/}).
987

    
988
@subsection Compilation under Cygwin
989

    
990
Please use Cygwin 1.7.x as the obsolete 1.5.x Cygwin versions lack
991
llrint() in its C library.
992

    
993
Install your Cygwin with all the "Base" packages, plus the
994
following "Devel" ones:
995
@example
996
binutils, gcc4-core, make, subversion, mingw-runtime, texi2html
997
@end example

And the following "Utils" one:
1000
@example
1001
diffutils
1002
@end example
1003

    
1004
Then run
1005

    
1006
@example
1007
./configure --enable-static --disable-shared
1008
@end example
1009

    
1010
to make a static build.
1011

    
1012
The current @code{gcc4-core} package is buggy and needs this flag to build
1013
shared libraries:
1014

    
1015
@example
1016
./configure --enable-shared --disable-static --extra-cflags=-fno-reorder-functions
1017
@end example
1018

    
1019
If you want to build FFmpeg with additional libraries, download Cygwin
1020
"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
1021
@example
1022
libogg-devel, libvorbis-devel
1023
@end example
1024

    
1025
These library packages are only available from Cygwin Ports
1026
(@url{http://sourceware.org/cygwinports/}) :
1027

    
1028
@example
1029
yasm, libSDL-devel, libdirac-devel, libfaac-devel, libfaad-devel, libgsm-devel,
1030
libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
1031
libxvidcore-devel
1032
@end example
1033

    
1034
The recommendation for libnut and x264 is to build them from source by
1035
yourself, as they evolve too quickly for Cygwin Ports to be up to date.
1036

    
1037
Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
1038
of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.

@subsection Crosscompilation for Windows under Cygwin
1041

    
1042
With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
1043

    
1044
Just install your Cygwin as explained before, plus these additional
1045
"Devel" packages:
1046
@example
1047
gcc-mingw-core, mingw-runtime, mingw-zlib
1048
@end example
1049

    
1050
and add some special flags to your configure invocation.
1051

    
1052
For a static build run
1053
@example
1054
./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1055
@end example
1056

    
1057
and for a build with shared libraries
1058
@example
1059
./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1060
@end example
