11 @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.

728 @section BeOS
729
730 BeOS support is broken in mysterious ways.
731
732 @section DOS
733
734 Using a cross-compiler is preferred for various reasons.
735
736 @subsection DJGPP
737
738 FFmpeg cannot be compiled because of broken system headers, add
739 @code{--extra-cflags=-U__STRICT_ANSI__} to the configure options as a
740 workaround.
741
742 @section OS/2
743
744 For information about compiling FFmpeg on OS/2 see
745 @url{http://www.edm2.com/index.php/FFmpeg}.
746
747 @section Unix-like
748
749 Some parts of FFmpeg cannot be built with version 2.15 of the GNU
750 assembler which is still provided by a few AMD64 distributions. To
751 make sure your compiler really uses the required version of gas
752 after a binutils upgrade, run:
753
754 @example
755 $(gcc -print-prog-name=as) --version
756 @end example
757
758 If not, then you should install a different compiler that has no
759 hard-coded path to gas. In the worst case pass @code{--disable-asm}
760 to configure.
761
762 @subsection BSD
763
764 BSD make will not build FFmpeg, you need to install and use GNU Make
765 (@file{gmake}).
766
767 @subsubsection FreeBSD
768
769 FreeBSD will not compile out-of-the-box due to broken system headers.
770 Passing @code{--extra-cflags=-D__BSD_VISIBLE} to configure will work
771 around the problem. This may have unexpected sideeffects, so use it at
772 your own risk. If you care about FreeBSD, please make an attempt at
773 getting the system headers fixed.
774
775 @subsection (Open)Solaris
776
777 GNU Make is required to build FFmpeg, so you have to invoke (@file{gmake}),
778 standard Solaris Make will not work. When building with a non-c99 front-end
779 (gcc, generic suncc) add either @code{--extra-libs=/usr/lib/values-xpg6.o}
780 or @code{--extra-libs=/usr/lib/64/values-xpg6.o} to the configure options
781 since the libc is not c99-compliant by default. The probes performed by
782 configure may raise an exception leading to the death of configure itself
783 due to a bug in the system shell. Simply invoke a different shell such as
784 bash directly to work around this:
785
786 @example
787 bash ./configure
788 @end example
789
790 @section Windows
791
792 To get help and instructions for building FFmpeg under Windows, check out
793 the FFmpeg Windows Help Forum at
794 @url{http://ffmpeg.arrozcru.org/}.
795
796 @subsection Native Windows compilation
797
798 FFmpeg can be built to run natively on Windows using the MinGW tools. Install
799 the latest versions of MSYS and MinGW from @url{http://www.mingw.org/}.
800 You can find detailed installation
801 instructions in the download section and the FAQ.
802
803 FFmpeg does not build out-of-the-box with the packages the automated MinGW
804 installer provides. It also requires coreutils to be installed and many other
805 packages updated to the latest version. The minimum version for some packages
806 are listed below:
807
808 @itemize
809 @item bash 3.1
810 @item msys-make 3.81-2 (note: not mingw32-make)
811 @item w32api 3.13
812 @item mingw-runtime 3.15
813 @end itemize
814
815 FFmpeg automatically passes @code{-fno-common} to the compiler to work around
816 a GCC bug (see @url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216}).
817
818 Within the MSYS shell, configure and make with:
819
820 @example
821 ./configure --enable-memalign-hack
822 make
823 make install
824 @end example
825
826 This will install @file{ffmpeg.exe} along with many other development files
827 to @file{/usr/local}. You may specify another install path using the
828 @code{--prefix} option in @file{configure}.
829
830 Notes:
831
832 @itemize
833
834 @item Building natively using MSYS can be sped up by disabling implicit rules
835 in the Makefile by calling @code{make -r} instead of plain @code{make}. This
836 speed up is close to non-existent for normal one-off builds and is only
837 noticeable when running make for a second time (for example in
838 @code{make install}).
839
840 @item In order to compile FFplay, you must have the MinGW development library
841 of SDL. Get it from @url{http://www.libsdl.org}.
842 Edit the @file{bin/sdl-config} script so that it points to the correct prefix
843 where SDL was installed. Verify that @file{sdl-config} can be launched from
844 the MSYS command line.
845
846 @item By using @code{./configure --enable-shared} when configuring FFmpeg,
847 you can build libavutil, libavcodec and libavformat as DLLs.
848
849 @end itemize
850
851 @subsection Microsoft Visual C++ compatibility
852
853 As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
854 want to use the libav* libraries in your own applications, you can still
855 compile those applications using MSVC++. But the libav* libraries you link
856 to @emph{must} be built with MinGW. However, you will not be able to debug
857 inside the libav* libraries, since MSVC++ does not recognize the debug
858 symbols generated by GCC.
859 We strongly recommend you to move over from MSVC++ to MinGW tools.
860
861 This description of how to use the FFmpeg libraries with MSVC++ is based on
862 Microsoft Visual C++ 2005 Express Edition. If you have a different version,
863 you might have to modify the procedures slightly.
864
865 @subsubsection Using static libraries
866
867 Assuming you have just built and installed FFmpeg in @file{/usr/local}.
868
869 @enumerate
870
871 @item Create a new console application ("File / New / Project") and then
872 select "Win32 Console Application". On the appropriate page of the
873 Application Wizard, uncheck the "Precompiled headers" option.
874
875 @item Write the source code for your application, or, for testing, just
876 copy the code from an existing sample application into the source file
877 that MSVC++ has already created for you. For example, you can copy
878 @file{libavformat/output-example.c} from the FFmpeg distribution.
879
880 @item Open the "Project / Properties" dialog box. In the "Configuration"
881 combo box, select "All Configurations" so that the changes you make will
882 affect both debug and release builds. In the tree view on the left hand
883 side, select "C/C++ / General", then edit the "Additional Include
884 Directories" setting to contain the path where the FFmpeg includes were
885 installed (i.e. @file{c:\msys\1.0\local\include}).
886 Do not add MinGW's include directory here, or the include files will
887 conflict with MSVC's.
888
889 @item Still in the "Project / Properties" dialog box, select
890 "Linker / General" from the tree view and edit the
891 "Additional Library Directories" setting to contain the @file{lib}
892 directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
893 the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
894 and the directory where MinGW's GCC libs are installed
895 (i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
896 "Linker / Input" from the tree view, and add the files @file{libavformat.a},
897 @file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
898 @file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
899 to the end of "Additional Dependencies".
900
901 @item Now, select "C/C++ / Code Generation" from the tree view. Select
902 "Debug" in the "Configuration" combo box. Make sure that "Runtime
903 Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
904 the "Configuration" combo box and make sure that "Runtime Library" is
905 set to "Multi-threaded DLL".
906
907 @item Click "OK" to close the "Project / Properties" dialog box.
908
909 @item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
910 Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
911 and install it in MSVC++'s include directory
912 (i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
913
914 @item MSVC++ also does not understand the @code{inline} keyword used by
915 FFmpeg, so you must add this line before @code{#include}ing libav*:
916 @example
917 #define inline _inline
918 @end example
919
920 @item Build your application, everything should work.
921
922 @end enumerate
923
924 @subsubsection Using shared libraries
925
926 This is how to create DLL and LIB files that are compatible with MSVC++:
927
928 @enumerate
929
930 @item Add a call to @file{vcvars32.bat} (which sets up the environment
931 variables for the Visual C++ tools) as the first line of @file{msys.bat}.
932 The standard location for @file{vcvars32.bat} is
933 @file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
934 and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
935 If this corresponds to your setup, add the following line as the first line
936 of @file{msys.bat}:
937
938 @example
939 call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
940 @end example
941
942 Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
943 and run @file{c:\msys\1.0\msys.bat} from there.
944
945 @item Within the MSYS shell, run @code{lib.exe}. If you get a help message
946 from @file{Microsoft (R) Library Manager}, this means your environment
947 variables are set up correctly, the @file{Microsoft (R) Library Manager}
948 is on the path and will be used by FFmpeg to create
949 MSVC++-compatible import libraries.
950
951 @item Build FFmpeg with
952
953 @example
954 ./configure --enable-shared --enable-memalign-hack
955 make
956 make install
957 @end example
958
959 Your install path (@file{/usr/local/} by default) should now have the
960 necessary DLL and LIB files under the @file{bin} directory.
961
962 @end enumerate
963
964 To use those files with MSVC++, do the same as you would do with
965 the static libraries, as described above. But in Step 4,
966 you should only need to add the directory where the LIB files are installed
967 (i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
968 installed in the @file{bin} directory. And instead of adding @file{libxx.a}
969 files, you should add @file{avcodec.lib}, @file{avformat.lib}, and
970 @file{avutil.lib}. There should be no need for @file{libmingwex.a},
971 @file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
972 statically linked into the DLLs. The @file{bin} directory contains a bunch
973 of DLL files, but the ones that are actually used to run your application
974 are the ones with a major version number in their filenames
975 (i.e. @file{avcodec-51.dll}).
976
977 @subsection Cross compilation for Windows with Linux
978
979 You must use the MinGW cross compilation tools available at
980 @url{http://www.mingw.org/}.
981
982 Then configure FFmpeg with the following options:
983 @example
984 ./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
985 @end example
986 (you can change the cross-prefix according to the prefix chosen for the
987 MinGW tools).
988
989 Then you can easily test FFmpeg with Wine
990 (@url{http://www.winehq.com/}).
991
992 @subsection Compilation under Cygwin
993
994 Please use Cygwin 1.7.x as the obsolete 1.5.x Cygwin versions lack
995 llrint() in its C library.
996
997 Install your Cygwin with all the "Base" packages, plus the
998 following "Devel" ones:
999 @example
1000 binutils, gcc4-core, make, subversion, mingw-runtime, texi2html
1001 @end example
1002
1003 And the following "Utils" one:
1004 @example
1005 diffutils
1006 @end example
1007
1008 Then run
1009
1010 @example
1011 ./configure --enable-static --disable-shared
1012 @end example
1013
1014 to make a static build.
1015
1016 The current @code{gcc4-core} package is buggy and needs this flag to build
1017 shared libraries:
1018
1019 @example
1020 ./configure --enable-shared --disable-static --extra-cflags=-fno-reorder-functions
1021 @end example
1022
1023 If you want to build FFmpeg with additional libraries, download Cygwin
1024 "Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
1025 @example
1026 libogg-devel, libvorbis-devel
1027 @end example
1028
1029 These library packages are only available from Cygwin Ports
1030 (@url{http://sourceware.org/cygwinports/}) :
1031
1032 @example
1033 yasm, libSDL-devel, libdirac-devel, libfaac-devel, libfaad-devel, libgsm-devel,
1034 libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
1035 libxvidcore-devel
1036 @end example
1037
1038 The recommendation for libnut and x264 is to build them from source by
1039 yourself, as they evolve too quickly for Cygwin Ports to be up to date.
1040
1041 Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
1042 of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
1043
1044 @subsection Crosscompilation for Windows under Cygwin
1045
1046 With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
1047
1048 Just install your Cygwin as explained before, plus these additional
1049 "Devel" packages:
1050 @example
1051 gcc-mingw-core, mingw-runtime, mingw-zlib
1052 @end example
1053
1054 and add some special flags to your configure invocation.
1055
1056 For a static build run
1057 @example
1058 ./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1059 @end example
1060
1061 and for a build with shared libraries
1062 @example
1063 ./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1064 @end example
