12 @chapter external libraries
13
14 Libav 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 Libav 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 Libav's license to LGPL version 3 (or if you have enabled
31 GPL components, GPL version 3) to use it.

766 @chapter Platform Specific information
767
768 @section DOS
769
770 Using a cross-compiler is preferred for various reasons.
771
772 @section OS/2
773
774 For information about compiling Libav on OS/2 see
775 @url{http://www.edm2.com/index.php/FFmpeg}.
776
777 @section Unix-like
778
779 Some parts of Libav cannot be built with version 2.15 of the GNU
780 assembler which is still provided by a few AMD64 distributions. To
781 make sure your compiler really uses the required version of gas
782 after a binutils upgrade, run:
783
784 @example
785 $(gcc -print-prog-name=as) --version
786 @end example
787
788 If not, then you should install a different compiler that has no
789 hard-coded path to gas. In the worst case pass @code{--disable-asm}
790 to configure.
791
792 @subsection BSD
793
794 BSD make will not build Libav, you need to install and use GNU Make
795 (@file{gmake}).
796
797 @subsection (Open)Solaris
798
799 GNU Make is required to build Libav, so you have to invoke (@file{gmake}),
800 standard Solaris Make will not work. When building with a non-c99 front-end
801 (gcc, generic suncc) add either @code{--extra-libs=/usr/lib/values-xpg6.o}
802 or @code{--extra-libs=/usr/lib/64/values-xpg6.o} to the configure options
803 since the libc is not c99-compliant by default. The probes performed by
804 configure may raise an exception leading to the death of configure itself
805 due to a bug in the system shell. Simply invoke a different shell such as
806 bash directly to work around this:
807
808 @example
809 bash ./configure
810 @end example
811
812 @subsection Darwin (MacOS X, iPhone)
813
814 MacOS X on PowerPC or ARM (iPhone) requires a preprocessor from
815 @url{http://github.com/yuvi/gas-preprocessor} to build the optimized
816 assembler functions. Just download the Perl script and put it somewhere
817 in your PATH, Libav's configure will pick it up automatically.
818
819 @section Windows
820
821 @subsection Native Windows compilation
822
823 Libav can be built to run natively on Windows using the MinGW tools. Install
824 the latest versions of MSYS and MinGW from @url{http://www.mingw.org/}.
825 You can find detailed installation
826 instructions in the download section and the FAQ.
827
828 Libav does not build out-of-the-box with the packages the automated MinGW
829 installer provides. It also requires coreutils to be installed and many other
830 packages updated to the latest version. The minimum version for some packages
831 are listed below:
832
833 @itemize
834 @item bash 3.1
835 @item msys-make 3.81-2 (note: not mingw32-make)
836 @item w32api 3.13
837 @item mingw-runtime 3.15
838 @end itemize
839
840 Libav automatically passes @code{-fno-common} to the compiler to work around
841 a GCC bug (see @url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216}).
842
843 Notes:
844
845 @itemize
846
847 @item Building natively using MSYS can be sped up by disabling implicit rules
848 in the Makefile by calling @code{make -r} instead of plain @code{make}. This
849 speed up is close to non-existent for normal one-off builds and is only
850 noticeable when running make for a second time (for example in
851 @code{make install}).
852
853 @item In order to compile AVplay, you must have the MinGW development library
854 of @uref{http://www.libsdl.org/, SDL}.
855 Edit the @file{bin/sdl-config} script so that it points to the correct prefix
856 where SDL was installed. Verify that @file{sdl-config} can be launched from
857 the MSYS command line.
858
859 @item By using @code{./configure --enable-shared} when configuring Libav,
860 you can build libavutil, libavcodec and libavformat as DLLs.
861
862 @end itemize
863
864 @subsection Microsoft Visual C++ compatibility
865
866 As stated in the FAQ, Libav will not compile under MSVC++. However, if you
867 want to use the libav* libraries in your own applications, you can still
868 compile those applications using MSVC++. But the libav* libraries you link
869 to @emph{must} be built with MinGW. However, you will not be able to debug
870 inside the libav* libraries, since MSVC++ does not recognize the debug
871 symbols generated by GCC.
872 We strongly recommend you to move over from MSVC++ to MinGW tools.
873
874 This description of how to use the Libav libraries with MSVC++ is based on
875 Microsoft Visual C++ 2005 Express Edition. If you have a different version,
876 you might have to modify the procedures slightly.
877
878 @subsubsection Using static libraries
879
880 Assuming you have just built and installed Libav in @file{/usr/local}.
881
882 @enumerate
883
884 @item Create a new console application ("File / New / Project") and then
885 select "Win32 Console Application". On the appropriate page of the
886 Application Wizard, uncheck the "Precompiled headers" option.
887
888 @item Write the source code for your application, or, for testing, just
889 copy the code from an existing sample application into the source file
890 that MSVC++ has already created for you. For example, you can copy
891 @file{libavformat/output-example.c} from the Libav distribution.
892
893 @item Open the "Project / Properties" dialog box. In the "Configuration"
894 combo box, select "All Configurations" so that the changes you make will
895 affect both debug and release builds. In the tree view on the left hand
896 side, select "C/C++ / General", then edit the "Additional Include
897 Directories" setting to contain the path where the Libav includes were
898 installed (i.e. @file{c:\msys\1.0\local\include}).
899 Do not add MinGW's include directory here, or the include files will
900 conflict with MSVC's.
901
902 @item Still in the "Project / Properties" dialog box, select
903 "Linker / General" from the tree view and edit the
904 "Additional Library Directories" setting to contain the @file{lib}
905 directory where Libav was installed (i.e. @file{c:\msys\1.0\local\lib}),
906 the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
907 and the directory where MinGW's GCC libs are installed
908 (i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
909 "Linker / Input" from the tree view, and add the files @file{libavformat.a},
910 @file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
911 @file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
912 to the end of "Additional Dependencies".
913
914 @item Now, select "C/C++ / Code Generation" from the tree view. Select
915 "Debug" in the "Configuration" combo box. Make sure that "Runtime
916 Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
917 the "Configuration" combo box and make sure that "Runtime Library" is
918 set to "Multi-threaded DLL".
919
920 @item Click "OK" to close the "Project / Properties" dialog box.
921
922 @item MSVC++ lacks some C99 header files that are fundamental for Libav.
923 Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
924 and install it in MSVC++'s include directory
925 (i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
926
927 @item MSVC++ also does not understand the @code{inline} keyword used by
928 Libav, so you must add this line before @code{#include}ing libav*:
929 @example
930 #define inline _inline
931 @end example
932
933 @item Build your application, everything should work.
934
935 @end enumerate
936
937 @subsubsection Using shared libraries
938
939 This is how to create DLL and LIB files that are compatible with MSVC++:
940
941 Within the MSYS shell, build Libav with
942
943 @example
944 ./configure --enable-shared
945 make
946 make install
947 @end example
948
949 Your install path (@file{/usr/local/} by default) should now have the
950 necessary DLL and LIB files under the @file{bin} directory.
951
952 Alternatively, build the libraries with a cross compiler, according to
953 the instructions below in @ref{Cross compilation for Windows with Linux}.
954
955 To use those files with MSVC++, do the same as you would do with
956 the static libraries, as described above. But in Step 4,
957 you should only need to add the directory where the LIB files are installed
958 (i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
959 installed in the @file{bin} directory. And instead of adding the static
960 libraries (@file{libxxx.a} files) you should add the MSVC import libraries
961 (@file{avcodec.lib}, @file{avformat.lib}, and
962 @file{avutil.lib}). Note that you should not use the GCC import
963 libraries (@file{libxxx.dll.a} files), as these will give you undefined
964 reference errors. There should be no need for @file{libmingwex.a},
965 @file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
966 statically linked into the DLLs.
967
968 Libav headers do not declare global data for Windows DLLs through the usual
969 dllexport/dllimport interface. Such data will be exported properly while
970 building, but to use them in your MSVC++ code you will have to edit the
971 appropriate headers and mark the data as dllimport. For example, in
972 libavutil/pixdesc.h you should have:
973 @example
974 extern __declspec(dllimport) const AVPixFmtDescriptor av_pix_fmt_descriptors[];
975 @end example
976
977 Note that using import libraries created by dlltool requires
978 the linker optimization option to be set to
979 "References: Keep Unreferenced Data (@code{/OPT:NOREF})", otherwise
980 the resulting binaries will fail during runtime. This isn't
981 required when using import libraries generated by lib.exe.
982 This issue is reported upstream at
983 @url{http://sourceware.org/bugzilla/show_bug.cgi?id=12633}.
984
985 To create import libraries that work with the @code{/OPT:REF} option
986 (which is enabled by default in Release mode), follow these steps:
987
988 @enumerate
989
990 @item Open @file{Visual Studio 2005 Command Prompt}.
991
992 Alternatively, in a normal command line prompt, call @file{vcvars32.bat}
993 which sets up the environment variables for the Visual C++ tools
994 (the standard location for this file is
995 @file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat}).
996
997 @item Enter the @file{bin} directory where the created LIB and DLL files
998 are stored.
999
1000 @item Generate new import libraries with @file{lib.exe}:
1001
1002 @example
1003 lib /machine:i386 /def:..\lib\avcodec-53.def /out:avcodec.lib
1004 lib /machine:i386 /def:..\lib\avdevice-53.def /out:avdevice.lib
1005 lib /machine:i386 /def:..\lib\avfilter-2.def /out:avfilter.lib
1006 lib /machine:i386 /def:..\lib\avformat-53.def /out:avformat.lib
1007 lib /machine:i386 /def:..\lib\avutil-51.def /out:avutil.lib
1008 lib /machine:i386 /def:..\lib\swscale-2.def /out:swscale.lib
1009 @end example
1010
1011 @end enumerate

1013 @anchor{Cross compilation for Windows with Linux}
1014 @subsection Cross compilation for Windows with Linux
1015
1016 You must use the MinGW cross compilation tools available at
1017 @url{http://www.mingw.org/}.
1018
1019 Then configure Libav with the following options:
1020 @example
1021 ./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
1022 @end example
1023 (you can change the cross-prefix according to the prefix chosen for the
1024 MinGW tools).
1025
1026 Then you can easily test Libav with @uref{http://www.winehq.com/, Wine}.
1027
1028 @subsection Compilation under Cygwin
1029
1030 Please use Cygwin 1.7.x as the obsolete 1.5.x Cygwin versions lack
1031 llrint() in its C library.
1032
1033 Install your Cygwin with all the "Base" packages, plus the
1034 following "Devel" ones:
1035 @example
1036 binutils, gcc4-core, make, git, mingw-runtime, texi2html
1037 @end example
1038
1039 And the following "Utils" one:
1040 @example
1041 diffutils
1042 @end example
1043
1044 Then run
1045
1046 @example
1047 ./configure
1048 @end example
1049
1050 to make a static build.
1051
1052 The current @code{gcc4-core} package is buggy and needs this flag to build
1053 shared libraries:
1054
1055 @example
1056 ./configure --enable-shared --disable-static --extra-cflags=-fno-reorder-functions
1057 @end example
1058
1059 If you want to build Libav with additional libraries, download Cygwin
1060 "Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
1061 @example
1062 libogg-devel, libvorbis-devel
1063 @end example
1064
1065 These library packages are only available from
1066 @uref{http://sourceware.org/cygwinports/, Cygwin Ports}:
1067
1068 @example
1069 yasm, libSDL-devel, libdirac-devel, libfaac-devel, libgsm-devel,
1070 libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
1071 libxvidcore-devel
1072 @end example
1073
1074 The recommendation for libnut and x264 is to build them from source by
1075 yourself, as they evolve too quickly for Cygwin Ports to be up to date.
1076
1077 Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
1078 of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
1079
1080 @subsection Crosscompilation for Windows under Cygwin
1081
1082 With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
1083
1084 Just install your Cygwin as explained before, plus these additional
1085 "Devel" packages:
1086 @example
1087 gcc-mingw-core, mingw-runtime, mingw-zlib
1088 @end example
1089
1090 and add some special flags to your configure invocation.
1091
1092 For a static build run
1093 @example
1094 ./configure --target-os=mingw32 --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1095 @end example
1096
1097 and for a build with shared libraries
1098 @example
1099 ./configure --target-os=mingw32 --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1100 @end example
