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.

681 @chapter Platform Specific information
682
683 @section BSD
684
685 BSD make will not build FFmpeg, you need to install and use GNU Make
686 (@file{gmake}).
687
688 @section Windows
689
690 To get help and instructions for building FFmpeg under Windows, check out
691 the FFmpeg Windows Help Forum at
692 @url{http://ffmpeg.arrozcru.org/}.
693
694 @subsection Native Windows compilation
695
696 FFmpeg can be built to run natively on Windows using the MinGW tools. Install
697 the latest versions of MSYS and MinGW from @url{http://www.mingw.org/}.
698 You can find detailed installation
699 instructions in the download section and the FAQ.
700
701 FFmpeg does not build out-of-the-box with the packages the automated MinGW
702 installer provides. It also requires coreutils to be installed and many other
703 packages updated to the latest version. The minimum version for some packages
704 are listed below:
705
706 @itemize
707 @item bash 3.1
708 @item msys-make 3.81-2 (note: not mingw32-make)
709 @item w32api 3.13
710 @item mingw-runtime 3.15
711 @end itemize
712
713 FFmpeg automatically passes @code{-fno-common} to the compiler to work around
714 a GCC bug (see @url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216}).
715
716 Within the MSYS shell, configure and make with:
717
718 @example
719 ./configure --enable-memalign-hack --extra-cflags=-fno-common
720 make
721 make install
722 @end example
723
724 This will install @file{ffmpeg.exe} along with many other development files
725 to @file{/usr/local}. You may specify another install path using the
726 @code{--prefix} option in @file{configure}.
727
728 Notes:
729
730 @itemize
731
732 @item In order to compile FFplay, you must have the MinGW development library
733 of SDL. Get it from @url{http://www.libsdl.org}.
734 Edit the @file{bin/sdl-config} script so that it points to the correct prefix
735 where SDL was installed. Verify that @file{sdl-config} can be launched from
736 the MSYS command line.
737
738 @item By using @code{./configure --enable-shared} when configuring FFmpeg,
739 you can build libavutil, libavcodec and libavformat as DLLs.
740
741 @end itemize
742
743 @subsection Microsoft Visual C++ compatibility
744
745 As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
746 want to use the libav* libraries in your own applications, you can still
747 compile those applications using MSVC++. But the libav* libraries you link
748 to @emph{must} be built with MinGW. However, you will not be able to debug
749 inside the libav* libraries, since MSVC++ does not recognize the debug
750 symbols generated by GCC.
751 We strongly recommend you to move over from MSVC++ to MinGW tools.
752
753 This description of how to use the FFmpeg libraries with MSVC++ is based on
754 Microsoft Visual C++ 2005 Express Edition. If you have a different version,
755 you might have to modify the procedures slightly.
756
757 @subsubsection Using static libraries
758
759 Assuming you have just built and installed FFmpeg in @file{/usr/local}.
760
761 @enumerate
762
763 @item Create a new console application ("File / New / Project") and then
764 select "Win32 Console Application". On the appropriate page of the
765 Application Wizard, uncheck the "Precompiled headers" option.
766
767 @item Write the source code for your application, or, for testing, just
768 copy the code from an existing sample application into the source file
769 that MSVC++ has already created for you. For example, you can copy
770 @file{libavformat/output-example.c} from the FFmpeg distribution.
771
772 @item Open the "Project / Properties" dialog box. In the "Configuration"
773 combo box, select "All Configurations" so that the changes you make will
774 affect both debug and release builds. In the tree view on the left hand
775 side, select "C/C++ / General", then edit the "Additional Include
776 Directories" setting to contain the path where the FFmpeg includes were
777 installed (i.e. @file{c:\msys\1.0\local\include}).
778 Do not add MinGW's include directory here, or the include files will
779 conflict with MSVC's.
780
781 @item Still in the "Project / Properties" dialog box, select
782 "Linker / General" from the tree view and edit the
783 "Additional Library Directories" setting to contain the @file{lib}
784 directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
785 the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
786 and the directory where MinGW's GCC libs are installed
787 (i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
788 "Linker / Input" from the tree view, and add the files @file{libavformat.a},
789 @file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
790 @file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
791 to the end of "Additional Dependencies".
792
793 @item Now, select "C/C++ / Code Generation" from the tree view. Select
794 "Debug" in the "Configuration" combo box. Make sure that "Runtime
795 Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
796 the "Configuration" combo box and make sure that "Runtime Library" is
797 set to "Multi-threaded DLL".
798
799 @item Click "OK" to close the "Project / Properties" dialog box.
800
801 @item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
802 Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
803 and install it in MSVC++'s include directory
804 (i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
805
806 @item MSVC++ also does not understand the @code{inline} keyword used by
807 FFmpeg, so you must add this line before @code{#include}ing libav*:
808 @example
809 #define inline _inline
810 @end example
811
812 @item Build your application, everything should work.
813
814 @end enumerate
815
816 @subsubsection Using shared libraries
817
818 This is how to create DLL and LIB files that are compatible with MSVC++:
819
820 @enumerate
821
822 @item Add a call to @file{vcvars32.bat} (which sets up the environment
823 variables for the Visual C++ tools) as the first line of @file{msys.bat}.
824 The standard location for @file{vcvars32.bat} is
825 @file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
826 and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
827 If this corresponds to your setup, add the following line as the first line
828 of @file{msys.bat}:
829
830 @example
831 call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
832 @end example
833
834 Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
835 and run @file{c:\msys\1.0\msys.bat} from there.
836
837 @item Within the MSYS shell, run @code{lib.exe}. If you get a help message
838 from @file{Microsoft (R) Library Manager}, this means your environment
839 variables are set up correctly, the @file{Microsoft (R) Library Manager}
840 is on the path and will be used by FFmpeg to create
841 MSVC++-compatible import libraries.
842
843 @item Build FFmpeg with
844
845 @example
846 ./configure --enable-shared --enable-memalign-hack
847 make
848 make install
849 @end example
850
851 Your install path (@file{/usr/local/} by default) should now have the
852 necessary DLL and LIB files under the @file{bin} directory.
853
854 @end enumerate
855
856 To use those files with MSVC++, do the same as you would do with
857 the static libraries, as described above. But in Step 4,
858 you should only need to add the directory where the LIB files are installed
859 (i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
860 installed in the @file{bin} directory. And instead of adding @file{libxx.a}
861 files, you should add @file{avcodec.lib}, @file{avformat.lib}, and
862 @file{avutil.lib}. There should be no need for @file{libmingwex.a},
863 @file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
864 statically linked into the DLLs. The @file{bin} directory contains a bunch
865 of DLL files, but the ones that are actually used to run your application
866 are the ones with a major version number in their filenames
867 (i.e. @file{avcodec-51.dll}).
868
869 @subsection Cross compilation for Windows with Linux
870
871 You must use the MinGW cross compilation tools available at
872 @url{http://www.mingw.org/}.
873
874 Then configure FFmpeg with the following options:
875 @example
876 ./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
877 @end example
878 (you can change the cross-prefix according to the prefix chosen for the
879 MinGW tools).
880
881 Then you can easily test FFmpeg with Wine
882 (@url{http://www.winehq.com/}).
883
884 @subsection Compilation under Cygwin
885
886 The main issue with the 1.5.x Cygwin versions is that newlib, its C library,
887 does not contain llrint(). You need to upgrade to the unstable 1.7.x versions,
888 or leverage the implementation in MinGW (as explained below).
889
890 Just install your Cygwin with all the "Base" packages, plus the
891 following "Devel" ones:
892 @example
893 binutils, gcc-core, make, subversion, mingw-runtime
894 @end example
895
896 And the following "Utils" one:
897 @example
898 diffutils
899 @end example
900
901 The experimental gcc4 package is still buggy, hence please
902 use the official gcc 3.4.4 or a 4.2.x compiled from source by yourself.
903
904 Install the current binutils-20080624-2 as they work fine (the old
905 binutils-20060709-1 proved buggy on shared builds).
906
907 Then create a small library that just contains llrint():
908
909 @example
910 ar x /usr/lib/mingw/libmingwex.a llrint.o
911 ar cq /usr/local/lib/libllrint.a llrint.o
912 @end example
913
914 Then run
915
916 @example
917 ./configure --enable-static --disable-shared --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
918 @end example
919
920 to make a static build or
921
922 @example
923 ./configure --enable-shared --disable-static --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
924 @end example
925
926 to build shared libraries.
927
928 If you want to build FFmpeg with additional libraries, download Cygwin
929 "Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
930 @example
931 libogg-devel, libvorbis-devel
932 @end example
933
934 These library packages are only available from Cygwin Ports
935 (@url{http://sourceware.org/cygwinports/}) :
936
937 @example
938 yasm, libSDL-devel, libdirac-devel, libfaac-devel, libfaad-devel, libgsm-devel,
939 libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
940 libxvidcore-devel
941 @end example
942
943 The recommendation for libnut and x264 is to build them from source by
944 yourself, as they evolve too quickly for Cygwin Ports to be up to date.
945
946 Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
947 of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
948
949 @subsection Crosscompilation for Windows under Cygwin
950
951 With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
952
953 Just install your Cygwin as explained before, plus these additional
954 "Devel" packages:
955 @example
956 gcc-mingw-core, mingw-runtime, mingw-zlib
957 @end example
958
959 and add some special flags to your configure invocation.
960
961 For a static build run
962 @example
963 ./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
964 @end example
965
966 and for a build with shared libraries
967 @example
968 ./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
969 @end example
970
971 @section BeOS
972
973 BeOS support is broken in mysterious ways.
974
975 @section OS/2
976
977 For information about compiling FFmpeg on OS/2 see
