@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.

719
(@file{gmake}).
720

    
721
@section Windows
722

    
723
To get help and instructions for building FFmpeg under Windows, check out

726

    
727
@subsection Native Windows compilation
728

    
729
FFmpeg can be built to run natively on Windows using the MinGW tools. Install
730
the latest versions of MSYS and MinGW from @url{http://www.mingw.org/}.
731
You can find detailed installation
732
instructions in the download section and the FAQ.
733

    
734
FFmpeg does not build out-of-the-box with the packages the automated MinGW
735
installer provides. It also requires coreutils to be installed and many other
736
packages updated to the latest version. The minimum version for some packages
737
are listed below:
738

    
739
@itemize
740
@item bash 3.1
741
@item msys-make 3.81-2 (note: not mingw32-make)
742
@item w32api 3.13
743
@item mingw-runtime 3.15
744
@end itemize
745

    
746
FFmpeg automatically passes @code{-fno-common} to the compiler to work around
747
a GCC bug (see @url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216}).
748

    
749
Within the MSYS shell, configure and make with:
750

    
751
@example
752
./configure --enable-memalign-hack
753
make
754
make install
755
@end example
756

    
757
This will install @file{ffmpeg.exe} along with many other development files
758
to @file{/usr/local}. You may specify another install path using the
759
@code{--prefix} option in @file{configure}.
760

    
761
Notes:
762

    
763
@itemize
764

    
765
@item Building natively using MSYS can be sped up by disabling implicit rules
766
in the Makefile by calling @code{make -r} instead of plain @code{make}. This
767
speed up is close to non-existent for normal one-off builds and is only
768
noticeable when running make for a second time (for example in
769
@code{make install}).
770

    
771
@item In order to compile FFplay, you must have the MinGW development library
772
of SDL. Get it from @url{http://www.libsdl.org}.
773
Edit the @file{bin/sdl-config} script so that it points to the correct prefix
774
where SDL was installed. Verify that @file{sdl-config} can be launched from
775
the MSYS command line.
776

    
777
@item By using @code{./configure --enable-shared} when configuring FFmpeg,
778
you can build libavutil, libavcodec and libavformat as DLLs.
779

    
780
@end itemize
781

    
782
@subsection Microsoft Visual C++ compatibility
783

    
784
As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
785
want to use the libav* libraries in your own applications, you can still
786
compile those applications using MSVC++. But the libav* libraries you link
787
to @emph{must} be built with MinGW. However, you will not be able to debug
788
inside the libav* libraries, since MSVC++ does not recognize the debug
789
symbols generated by GCC.
790
We strongly recommend you to move over from MSVC++ to MinGW tools.
791

    
792
This description of how to use the FFmpeg libraries with MSVC++ is based on
793
Microsoft Visual C++ 2005 Express Edition. If you have a different version,
794
you might have to modify the procedures slightly.
795

    
796
@subsubsection Using static libraries
797

    
798
Assuming you have just built and installed FFmpeg in @file{/usr/local}.
799

    
800
@enumerate
801

    
802
@item Create a new console application ("File / New / Project") and then
803
select "Win32 Console Application". On the appropriate page of the
804
Application Wizard, uncheck the "Precompiled headers" option.
805

    
806
@item Write the source code for your application, or, for testing, just
807
copy the code from an existing sample application into the source file
808
that MSVC++ has already created for you. For example, you can copy
809
@file{libavformat/output-example.c} from the FFmpeg distribution.
810

    
811
@item Open the "Project / Properties" dialog box. In the "Configuration"
812
combo box, select "All Configurations" so that the changes you make will
813
affect both debug and release builds. In the tree view on the left hand
814
side, select "C/C++ / General", then edit the "Additional Include
815
Directories" setting to contain the path where the FFmpeg includes were
816
installed (i.e. @file{c:\msys\1.0\local\include}).
817
Do not add MinGW's include directory here, or the include files will
818
conflict with MSVC's.
819

    
820
@item Still in the "Project / Properties" dialog box, select
821
"Linker / General" from the tree view and edit the
822
"Additional Library Directories" setting to contain the @file{lib}
823
directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
824
the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
825
and the directory where MinGW's GCC libs are installed
826
(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
827
"Linker / Input" from the tree view, and add the files @file{libavformat.a},
828
@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
829
@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
830
to the end of "Additional Dependencies".
831

    
832
@item Now, select "C/C++ / Code Generation" from the tree view. Select
833
"Debug" in the "Configuration" combo box. Make sure that "Runtime
834
Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
835
the "Configuration" combo box and make sure that "Runtime Library" is
836
set to "Multi-threaded DLL".
837

    
838
@item Click "OK" to close the "Project / Properties" dialog box.
839

    
840
@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
841
Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
842
and install it in MSVC++'s include directory
843
(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
844

    
845
@item MSVC++ also does not understand the @code{inline} keyword used by
846
FFmpeg, so you must add this line before @code{#include}ing libav*:
847
@example
848
#define inline _inline
849
@end example
850

    
851
@item Build your application, everything should work.
852

    
853
@end enumerate
854

    
855
@subsubsection Using shared libraries
856

    
857
This is how to create DLL and LIB files that are compatible with MSVC++:
858

    
859
@enumerate
860

    
861
@item Add a call to @file{vcvars32.bat} (which sets up the environment
862
variables for the Visual C++ tools) as the first line of @file{msys.bat}.
863
The standard location for @file{vcvars32.bat} is
864
@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
865
and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
866
If this corresponds to your setup, add the following line as the first line
867
of @file{msys.bat}:
868

    
869
@example
870
call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
871
@end example
872

    
873
Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
874
and run @file{c:\msys\1.0\msys.bat} from there.
875

    
876
@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
877
from @file{Microsoft (R) Library Manager}, this means your environment
878
variables are set up correctly, the @file{Microsoft (R) Library Manager}
879
is on the path and will be used by FFmpeg to create
880
MSVC++-compatible import libraries.
881

    
882
@item Build FFmpeg with
883

    
884
@example
885
./configure --enable-shared --enable-memalign-hack
886
make
887
make install
888
@end example
889

    
890
Your install path (@file{/usr/local/} by default) should now have the
891
necessary DLL and LIB files under the @file{bin} directory.
892

    
893
@end enumerate
894

    
895
To use those files with MSVC++, do the same as you would do with
896
the static libraries, as described above. But in Step 4,
897
you should only need to add the directory where the LIB files are installed
898
(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
899
installed in the @file{bin} directory. And instead of adding @file{libxx.a}
900
files, you should add @file{avcodec.lib}, @file{avformat.lib}, and
901
@file{avutil.lib}. There should be no need for @file{libmingwex.a},
902
@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
903
statically linked into the DLLs. The @file{bin} directory contains a bunch
904
of DLL files, but the ones that are actually used to run your application
905
are the ones with a major version number in their filenames
906
(i.e. @file{avcodec-51.dll}).
907

    
908
@subsection Cross compilation for Windows with Linux
909

    
910
You must use the MinGW cross compilation tools available at
911
@url{http://www.mingw.org/}.
912

    
913
Then configure FFmpeg with the following options:
914
@example
915
./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
916
@end example
917
(you can change the cross-prefix according to the prefix chosen for the
918
MinGW tools).
919

    
920
Then you can easily test FFmpeg with Wine
921
(@url{http://www.winehq.com/}).
922

    
923
@subsection Compilation under Cygwin
924

    
925
The main issue with the 1.5.x Cygwin versions is that newlib, its C library,
926
does not contain llrint().  You need to upgrade to the unstable 1.7.x versions,
927
or leverage the implementation in MinGW (as explained below).
928

    
929
Just install your Cygwin with all the "Base" packages, plus the
930
following "Devel" ones:
931
@example
932
binutils, gcc-core, make, subversion, mingw-runtime
933
@end example
934

    
935
And the following "Utils" one:
936
@example
937
diffutils
938
@end example
939

    
940
The experimental gcc4 package is still buggy, hence please
941
use the official gcc 3.4.4 or a 4.2.x compiled from source by yourself.
942

    
943
Install the current binutils-20080624-2 as they work fine (the old
944
binutils-20060709-1 proved buggy on shared builds).
945

    
946
Then create a small library that just contains llrint():
947

    
948
@example
949
ar x /usr/lib/mingw/libmingwex.a llrint.o
950
ar cq /usr/local/lib/libllrint.a llrint.o
951
@end example
952

    
953
Then run
954

    
955
@example
956
./configure --enable-static --disable-shared  --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
957
@end example
958

    
959
to make a static build or
960

    
961
@example
962
./configure --enable-shared --disable-static  --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
963
@end example
964

    
965
to build shared libraries.
966

    
967
If you want to build FFmpeg with additional libraries, download Cygwin
968
"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
969
@example
970
libogg-devel, libvorbis-devel
971
@end example
972

    
973
These library packages are only available from Cygwin Ports
974
(@url{http://sourceware.org/cygwinports/}) :
975

    
976
@example
977
yasm, libSDL-devel, libdirac-devel, libfaac-devel, libfaad-devel, libgsm-devel,
978
libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
979
libxvidcore-devel
980
@end example
981

    
982
The recommendation for libnut and x264 is to build them from source by
983
yourself, as they evolve too quickly for Cygwin Ports to be up to date.
984

    
985
Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
986
of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
987

    
988
@subsection Crosscompilation for Windows under Cygwin
989

    
990
With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
991

    
992
Just install your Cygwin as explained before, plus these additional
993
"Devel" packages:
994
@example
995
gcc-mingw-core, mingw-runtime, mingw-zlib
996
@end example
997

    
998
and add some special flags to your configure invocation.
999

    
1000
For a static build run
1001
@example
1002
./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1003
@end example
