11@chapter external libraries
12
13FFmpeg can be hooked up with a number of external libraries to add support
14for more formats. None of them are used by default, their use has to be
15explicitly requested by passing the appropriate flags to @file{./configure}.
16
17@section AMR
18
50e4d833
DB
19AMR comes in two different flavors, wideband and narrowband. FFmpeg can make
20use of the AMR wideband (floating-point mode) and the AMR narrowband
0b175caa
DB
21(floating-point mode) reference decoders and encoders (libamr) as well as
22the OpenCORE libraries for AMR-NB decoding/encoding and AMR-WB decoding.
23
24@subsection OpenCORE
25
26Go to @url{http://gitorious.org/opencore-amr/} and follow the instructions for
27installing the libraries. Then pass @code{--enable-libopencore-amrnb} and/or
28@code{--enable-libopencore-amrwb} to configure to enable the libraries.
29
30Note that OpenCORE is under the Apache License 2.0 (see
31@url{http://www.apache.org/licenses/LICENSE-2.0} for details), which is
32incompatible with the LGPL version 2.1 and GPL version 2. You have to
33upgrade FFmpeg's license to LGPL version 3 (or if you have enabled
34GPL components, GPL version 3) to use it.

757want to use the libav* libraries in your own applications, you can still
758compile those applications using MSVC++. But the libav* libraries you link
759to @emph{must} be built with MinGW. However, you will not be able to debug
760inside the libav* libraries, since MSVC++ does not recognize the debug
761symbols generated by GCC.
762We strongly recommend you to move over from MSVC++ to MinGW tools.

764This description of how to use the FFmpeg libraries with MSVC++ is based on
765Microsoft Visual C++ 2005 Express Edition. If you have a different version,
766you might have to modify the procedures slightly.
d0e1cd3d 767
c1989552 768@subsubsection Using static libraries
d0e1cd3d 769
c1989552 770Assuming you have just built and installed FFmpeg in @file{/usr/local}.
d0e1cd3d
DB
771
772@enumerate
773
774@item Create a new console application ("File / New / Project") and then
775select "Win32 Console Application". On the appropriate page of the
776Application Wizard, uncheck the "Precompiled headers" option.
777
778@item Write the source code for your application, or, for testing, just
779copy the code from an existing sample application into the source file
c1989552 780that MSVC++ has already created for you. For example, you can copy
d95a0c67 781@file{libavformat/output-example.c} from the FFmpeg distribution.
d0e1cd3d
DB
782
783@item Open the "Project / Properties" dialog box. In the "Configuration"
784combo box, select "All Configurations" so that the changes you make will
785affect both debug and release builds. In the tree view on the left hand
786side, select "C/C++ / General", then edit the "Additional Include
c1989552
RP
787Directories" setting to contain the path where the FFmpeg includes were
788installed (i.e. @file{c:\msys\1.0\local\include}).
f010d377
RP
789Do not add MinGW's include directory here, or the include files will
790conflict with MSVC's.
c1989552
RP
791
792@item Still in the "Project / Properties" dialog box, select
793"Linker / General" from the tree view and edit the
794"Additional Library Directories" setting to contain the @file{lib}
795directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
796the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
797and the directory where MinGW's GCC libs are installed
798(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
799"Linker / Input" from the tree view, and add the files @file{libavformat.a},
800@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
801@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
802to the end of "Additional Dependencies".
d0e1cd3d
DB
803
804@item Now, select "C/C++ / Code Generation" from the tree view. Select
805"Debug" in the "Configuration" combo box. Make sure that "Runtime
806Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
807the "Configuration" combo box and make sure that "Runtime Library" is
808set to "Multi-threaded DLL".
809
c1989552
RP
810@item Click "OK" to close the "Project / Properties" dialog box.
811
812@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
813Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
814and install it in MSVC++'s include directory
815(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
816
817@item MSVC++ also does not understand the @code{inline} keyword used by
818FFmpeg, so you must add this line before @code{#include}ing libav*:
819@example
820#define inline _inline
821@end example
822
c1989552
RP
823@item Build your application, everything should work.
824
825@end enumerate
826
827@subsubsection Using shared libraries
828
829This is how to create DLL and LIB files that are compatible with MSVC++:
830
831@enumerate
832
833@item Add a call to @file{vcvars32.bat} (which sets up the environment
834variables for the Visual C++ tools) as the first line of @file{msys.bat}.
835The standard location for @file{vcvars32.bat} is
836@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
837and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
838If this corresponds to your setup, add the following line as the first line
839of @file{msys.bat}:
840
841@example
842call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
843@end example
844
845Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
846and run @file{c:\msys\1.0\msys.bat} from there.
847
848@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
849from @file{Microsoft (R) Library Manager}, this means your environment
850variables are set up correctly, the @file{Microsoft (R) Library Manager}
851is on the path and will be used by FFmpeg to create
852MSVC++-compatible import libraries.
853
854@item Build FFmpeg with
855
856@example
857./configure --enable-shared --enable-memalign-hack
858make
859make install
860@end example
861
862Your install path (@file{/usr/local/} by default) should now have the
863necessary DLL and LIB files under the @file{bin} directory.
d0e1cd3d
DB
864
865@end enumerate
866
c1989552
RP
867To use those files with MSVC++, do the same as you would do with
868the static libraries, as described above. But in Step 4,
869you should only need to add the directory where the LIB files are installed
870(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
871installed in the @file{bin} directory. And instead of adding @file{libxx.a}
872files, you should add @file{avcodec.lib}, @file{avformat.lib}, and
873@file{avutil.lib}. There should be no need for @file{libmingwex.a},
874@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
875statically linked into the DLLs. The @file{bin} directory contains a bunch
876of DLL files, but the ones that are actually used to run your application
877are the ones with a major version number in their filenames
878(i.e. @file{avcodec-51.dll}).
879

DB
880@subsection Cross compilation for Windows with Linux
881
882You must use the MinGW cross compilation tools available at
883@url{http://www.mingw.org/}.
884
885Then configure FFmpeg with the following options:
886@example
887./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
888@end example
889(you can change the cross-prefix according to the prefix chosen for the
890MinGW tools).
891
892Then you can easily test FFmpeg with Wine
893(@url{http://www.winehq.com/}).
894
895@subsection Compilation under Cygwin
896
8484503e
VP
897The main issue with the 1.5.x Cygwin versions is that newlib, its C library,
898does not contain llrint(). You need to upgrade to the unstable 1.7.x versions,
899or leverage the implementation in MinGW (as explained below).
d0e1cd3d
DB
900
901Just install your Cygwin with all the "Base" packages, plus the
902following "Devel" ones:
903@example
f496ab12 904binutils, gcc-core, make, subversion, mingw-runtime, diffutils
d0e1cd3d
DB
905@end example
906
666a1b34
VP
907The experimental gcc4 package is still buggy, hence please
908use the official gcc 3.4.4 or a 4.2.x compiled from source by yourself.
909
8484503e
VP
910Install the current binutils-20080624-2 as they work fine (the old
911binutils-20060709-1 proved buggy on shared builds).
d0e1cd3d 912
29c3d42b
VP
913Then create a small library that just contains llrint():
914
915@example
916ar x /usr/lib/mingw/libmingwex.a llrint.o
917ar cq /usr/local/lib/libllrint.a llrint.o
918@end example
919
d0e1cd3d
DB
920Then run
921
922@example
29c3d42b 923./configure --enable-static --disable-shared --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
924@end example
925
926to make a static build or
927
928@example
29c3d42b 929./configure --enable-shared --disable-static --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
930@end example
931
932to build shared libraries.
933
934If you want to build FFmpeg with additional libraries, download Cygwin
5dd9799d
VP
935"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
936@example
937libogg-devel, libvorbis-devel
938@end example
939
940These library packages are only available from Cygwin Ports
be8497b0 941(@url{http://sourceware.org/cygwinports/}) :
5dd9799d
VP
942
943@example
944yasm, libSDL-devel, libdirac-devel, libfaac-devel, libfaad-devel, libgsm-devel,
945libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
946libxvidcore-devel
947@end example
948
949The recommendation for libnut and x264 is to build them from source by
950yourself, as they evolve too quickly for Cygwin Ports to be up to date.
d0e1cd3d 951

VP
952Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
953of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
954
d0e1cd3d
DB
955@subsection Crosscompilation for Windows under Cygwin
956
957With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
958
959Just install your Cygwin as explained before, plus these additional
960"Devel" packages:
961@example
962gcc-mingw-core, mingw-runtime, mingw-zlib
963@end example
964
965and add some special flags to your configure invocation.
966
967For a static build run
968@example
969./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
970@end example
971
972and for a build with shared libraries
973@example
974./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
975@end example
