744
c1989552 745Within the MSYS shell, configure and make with:
d0e1cd3d 746
c1989552 747@example
1a04d4c7 748./configure --enable-memalign-hack
c1989552
RP
749make
750make install
751@end example
d0e1cd3d 752
c1989552
RP
753This will install @file{ffmpeg.exe} along with many other development files
754to @file{/usr/local}. You may specify another install path using the
755@code{--prefix} option in @file{configure}.

d0e1cd3d 760

RP
761@item Building natively using MSYS can be sped up by disabling implicit rules
762in the Makefile by calling @code{make -r} instead of plain @code{make}. This
763speed up is close to non-existent for normal one-off builds and is only
764noticeable when running make for a second time (for example in
765@code{make install}).
766
c1989552
RP
767@item In order to compile FFplay, you must have the MinGW development library
768of SDL. Get it from @url{http://www.libsdl.org}.
769Edit the @file{bin/sdl-config} script so that it points to the correct prefix
770where SDL was installed. Verify that @file{sdl-config} can be launched from
771the MSYS command line.
d0e1cd3d 772
d0e1cd3d 773@item By using @code{./configure --enable-shared} when configuring FFmpeg,
c1989552 774you can build libavutil, libavcodec and libavformat as DLLs.

RP
780As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
781want to use the libav* libraries in your own applications, you can still
782compile those applications using MSVC++. But the libav* libraries you link
783to @emph{must} be built with MinGW. However, you will not be able to debug
784inside the libav* libraries, since MSVC++ does not recognize the debug
785symbols generated by GCC.
786We strongly recommend you to move over from MSVC++ to MinGW tools.
d0e1cd3d 787
c1989552
RP
788This description of how to use the FFmpeg libraries with MSVC++ is based on
789Microsoft Visual C++ 2005 Express Edition. If you have a different version,
790you might have to modify the procedures slightly.
d0e1cd3d 791
c1989552 792@subsubsection Using static libraries
d0e1cd3d 793
c1989552 794Assuming you have just built and installed FFmpeg in @file{/usr/local}.
d0e1cd3d
DB
795
796@enumerate
797
798@item Create a new console application ("File / New / Project") and then
799select "Win32 Console Application". On the appropriate page of the
800Application Wizard, uncheck the "Precompiled headers" option.
801
802@item Write the source code for your application, or, for testing, just
803copy the code from an existing sample application into the source file
c1989552 804that MSVC++ has already created for you. For example, you can copy
d95a0c67 805@file{libavformat/output-example.c} from the FFmpeg distribution.
d0e1cd3d
DB
806
807@item Open the "Project / Properties" dialog box. In the "Configuration"
808combo box, select "All Configurations" so that the changes you make will
809affect both debug and release builds. In the tree view on the left hand
810side, select "C/C++ / General", then edit the "Additional Include
c1989552
RP
811Directories" setting to contain the path where the FFmpeg includes were
812installed (i.e. @file{c:\msys\1.0\local\include}).
f010d377
RP
813Do not add MinGW's include directory here, or the include files will
814conflict with MSVC's.
c1989552
RP
815
816@item Still in the "Project / Properties" dialog box, select
817"Linker / General" from the tree view and edit the
818"Additional Library Directories" setting to contain the @file{lib}
819directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
820the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
821and the directory where MinGW's GCC libs are installed
822(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
823"Linker / Input" from the tree view, and add the files @file{libavformat.a},
824@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
825@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
826to the end of "Additional Dependencies".
d0e1cd3d
DB
827
828@item Now, select "C/C++ / Code Generation" from the tree view. Select
829"Debug" in the "Configuration" combo box. Make sure that "Runtime
830Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
831the "Configuration" combo box and make sure that "Runtime Library" is
832set to "Multi-threaded DLL".
833
c1989552
RP
834@item Click "OK" to close the "Project / Properties" dialog box.
835
836@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
837Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
838and install it in MSVC++'s include directory
839(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
840
841@item MSVC++ also does not understand the @code{inline} keyword used by
842FFmpeg, so you must add this line before @code{#include}ing libav*:
843@example
844#define inline _inline
845@end example
846
c1989552
RP
847@item Build your application, everything should work.
848
849@end enumerate
850
851@subsubsection Using shared libraries
852
853This is how to create DLL and LIB files that are compatible with MSVC++:
854
855@enumerate
856
857@item Add a call to @file{vcvars32.bat} (which sets up the environment
858variables for the Visual C++ tools) as the first line of @file{msys.bat}.
859The standard location for @file{vcvars32.bat} is
860@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
861and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
862If this corresponds to your setup, add the following line as the first line
863of @file{msys.bat}:
864
865@example
866call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
867@end example
868
869Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
870and run @file{c:\msys\1.0\msys.bat} from there.
871
872@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
873from @file{Microsoft (R) Library Manager}, this means your environment
874variables are set up correctly, the @file{Microsoft (R) Library Manager}
875is on the path and will be used by FFmpeg to create
876MSVC++-compatible import libraries.
877
878@item Build FFmpeg with
879
880@example
881./configure --enable-shared --enable-memalign-hack
882make
883make install
884@end example
885
886Your install path (@file{/usr/local/} by default) should now have the
887necessary DLL and LIB files under the @file{bin} directory.
d0e1cd3d
DB
888
889@end enumerate
890
c1989552
RP
891To use those files with MSVC++, do the same as you would do with
892the static libraries, as described above. But in Step 4,
893you should only need to add the directory where the LIB files are installed
894(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
895installed in the @file{bin} directory. And instead of adding @file{libxx.a}
896files, you should add @file{avcodec.lib}, @file{avformat.lib}, and
897@file{avutil.lib}. There should be no need for @file{libmingwex.a},
898@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
899statically linked into the DLLs. The @file{bin} directory contains a bunch
900of DLL files, but the ones that are actually used to run your application
901are the ones with a major version number in their filenames
902(i.e. @file{avcodec-51.dll}).
903

DB
904@subsection Cross compilation for Windows with Linux
905
906You must use the MinGW cross compilation tools available at
907@url{http://www.mingw.org/}.
908
909Then configure FFmpeg with the following options:
910@example
911./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
912@end example
913(you can change the cross-prefix according to the prefix chosen for the
914MinGW tools).
915
916Then you can easily test FFmpeg with Wine
917(@url{http://www.winehq.com/}).
918
919@subsection Compilation under Cygwin
920
8484503e
VP
921The main issue with the 1.5.x Cygwin versions is that newlib, its C library,
922does not contain llrint(). You need to upgrade to the unstable 1.7.x versions,
923or leverage the implementation in MinGW (as explained below).
d0e1cd3d
DB
924
925Just install your Cygwin with all the "Base" packages, plus the
926following "Devel" ones:
927@example
71ecc16b
RP
928binutils, gcc-core, make, subversion, mingw-runtime
929@end example
930
931And the following "Utils" one:
932@example
933diffutils
d0e1cd3d
DB
934@end example
935
666a1b34
VP
936The experimental gcc4 package is still buggy, hence please
937use the official gcc 3.4.4 or a 4.2.x compiled from source by yourself.
938
8484503e
VP
939Install the current binutils-20080624-2 as they work fine (the old
940binutils-20060709-1 proved buggy on shared builds).
d0e1cd3d 941
29c3d42b
VP
942Then create a small library that just contains llrint():
943
944@example
945ar x /usr/lib/mingw/libmingwex.a llrint.o
946ar cq /usr/local/lib/libllrint.a llrint.o
947@end example
948
d0e1cd3d
DB
949Then run
950
951@example
29c3d42b 952./configure --enable-static --disable-shared --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
953@end example
954
955to make a static build or
956
957@example
29c3d42b 958./configure --enable-shared --disable-static --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
959@end example
960
961to build shared libraries.
962
963If you want to build FFmpeg with additional libraries, download Cygwin
5dd9799d
VP
964"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
965@example
966libogg-devel, libvorbis-devel
967@end example
968
969These library packages are only available from Cygwin Ports
be8497b0 970(@url{http://sourceware.org/cygwinports/}) :
5dd9799d
VP
971
972@example
973yasm, libSDL-devel, libdirac-devel, libfaac-devel, libfaad-devel, libgsm-devel,
974libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
975libxvidcore-devel
976@end example
977
978The recommendation for libnut and x264 is to build them from source by
979yourself, as they evolve too quickly for Cygwin Ports to be up to date.
d0e1cd3d 980

VP
981Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
982of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
983
d0e1cd3d
DB
984@subsection Crosscompilation for Windows under Cygwin
985
986With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
987
988Just install your Cygwin as explained before, plus these additional
989"Devel" packages:
990@example
991gcc-mingw-core, mingw-runtime, mingw-zlib
992@end example
993
994and add some special flags to your configure invocation.
995
996For a static build run
997@example
998./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
999@end example
1000
1001and for a build with shared libraries
1002@example
1003./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1004@end example
