739@item Building natively using MSYS can be sped up by disabling implicit rules
740in the Makefile by calling @code{make -r} instead of plain @code{make}. This
741speed up is close to non-existent for normal one-off builds and is only
742noticeable when running make for a second time (for example in
743@code{make install}).

745@item In order to compile FFplay, you must have the MinGW development library
746of SDL. Get it from @url{http://www.libsdl.org}.
747Edit the @file{bin/sdl-config} script so that it points to the correct prefix
748where SDL was installed. Verify that @file{sdl-config} can be launched from

758As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
759want to use the libav* libraries in your own applications, you can still
760compile those applications using MSVC++. But the libav* libraries you link
761to @emph{must} be built with MinGW. However, you will not be able to debug
762inside the libav* libraries, since MSVC++ does not recognize the debug
763symbols generated by GCC.
764We strongly recommend you to move over from MSVC++ to MinGW tools.
d0e1cd3d 765

766This description of how to use the FFmpeg libraries with MSVC++ is based on
767Microsoft Visual C++ 2005 Express Edition. If you have a different version,
768you might have to modify the procedures slightly.

c1989552 770@subsubsection Using static libraries
d0e1cd3d 771
c1989552 772Assuming you have just built and installed FFmpeg in @file{/usr/local}.
d0e1cd3d
DB
773
774@enumerate
775
776@item Create a new console application ("File / New / Project") and then
777select "Win32 Console Application". On the appropriate page of the
778Application Wizard, uncheck the "Precompiled headers" option.
779
780@item Write the source code for your application, or, for testing, just
781copy the code from an existing sample application into the source file
c1989552 782that MSVC++ has already created for you. For example, you can copy
d95a0c67 783@file{libavformat/output-example.c} from the FFmpeg distribution.
d0e1cd3d
DB
784
785@item Open the "Project / Properties" dialog box. In the "Configuration"
786combo box, select "All Configurations" so that the changes you make will
787affect both debug and release builds. In the tree view on the left hand
788side, select "C/C++ / General", then edit the "Additional Include
c1989552
RP
789Directories" setting to contain the path where the FFmpeg includes were
790installed (i.e. @file{c:\msys\1.0\local\include}).
f010d377
RP
791Do not add MinGW's include directory here, or the include files will
792conflict with MSVC's.
c1989552
RP
793
794@item Still in the "Project / Properties" dialog box, select
795"Linker / General" from the tree view and edit the
796"Additional Library Directories" setting to contain the @file{lib}
797directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
798the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
799and the directory where MinGW's GCC libs are installed
800(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
801"Linker / Input" from the tree view, and add the files @file{libavformat.a},
802@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
803@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
804to the end of "Additional Dependencies".
d0e1cd3d
DB
805
806@item Now, select "C/C++ / Code Generation" from the tree view. Select
807"Debug" in the "Configuration" combo box. Make sure that "Runtime
808Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
809the "Configuration" combo box and make sure that "Runtime Library" is
810set to "Multi-threaded DLL".

c1989552
RP
812@item Click "OK" to close the "Project / Properties" dialog box.
813
814@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
815Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
816and install it in MSVC++'s include directory
817(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
818
819@item MSVC++ also does not understand the @code{inline} keyword used by
820FFmpeg, so you must add this line before @code{#include}ing libav*:
821@example
822#define inline _inline
823@end example
824
c1989552
RP
825@item Build your application, everything should work.
826
827@end enumerate
828
829@subsubsection Using shared libraries
830
831This is how to create DLL and LIB files that are compatible with MSVC++:
832
833@enumerate
834
835@item Add a call to @file{vcvars32.bat} (which sets up the environment
836variables for the Visual C++ tools) as the first line of @file{msys.bat}.
837The standard location for @file{vcvars32.bat} is
838@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
839and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
840If this corresponds to your setup, add the following line as the first line
841of @file{msys.bat}:
842
843@example
844call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
845@end example
846
847Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
848and run @file{c:\msys\1.0\msys.bat} from there.
849
850@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
851from @file{Microsoft (R) Library Manager}, this means your environment
852variables are set up correctly, the @file{Microsoft (R) Library Manager}
853is on the path and will be used by FFmpeg to create
854MSVC++-compatible import libraries.
855
856@item Build FFmpeg with
857
858@example
859./configure --enable-shared --enable-memalign-hack
860make
861make install
862@end example
863
864Your install path (@file{/usr/local/} by default) should now have the
865necessary DLL and LIB files under the @file{bin} directory.
d0e1cd3d
DB
866
867@end enumerate
868
c1989552
RP
869To use those files with MSVC++, do the same as you would do with
870the static libraries, as described above. But in Step 4,
871you should only need to add the directory where the LIB files are installed
872(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
873installed in the @file{bin} directory. And instead of adding @file{libxx.a}
874files, you should add @file{avcodec.lib}, @file{avformat.lib}, and
875@file{avutil.lib}. There should be no need for @file{libmingwex.a},
876@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
877statically linked into the DLLs. The @file{bin} directory contains a bunch
878of DLL files, but the ones that are actually used to run your application
879are the ones with a major version number in their filenames
880(i.e. @file{avcodec-51.dll}).
881

DB
882@subsection Cross compilation for Windows with Linux
883
884You must use the MinGW cross compilation tools available at
885@url{http://www.mingw.org/}.
886
887Then configure FFmpeg with the following options:
888@example
889./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
890@end example
891(you can change the cross-prefix according to the prefix chosen for the
892MinGW tools).
893
894Then you can easily test FFmpeg with Wine
895(@url{http://www.winehq.com/}).
896
897@subsection Compilation under Cygwin
898
8484503e
VP
899The main issue with the 1.5.x Cygwin versions is that newlib, its C library,
900does not contain llrint(). You need to upgrade to the unstable 1.7.x versions,
901or leverage the implementation in MinGW (as explained below).
d0e1cd3d
DB
902
903Just install your Cygwin with all the "Base" packages, plus the
904following "Devel" ones:
905@example
71ecc16b
RP
906binutils, gcc-core, make, subversion, mingw-runtime
907@end example
908
909And the following "Utils" one:
910@example
911diffutils
d0e1cd3d
DB
912@end example
913
666a1b34
VP
914The experimental gcc4 package is still buggy, hence please
915use the official gcc 3.4.4 or a 4.2.x compiled from source by yourself.
916
8484503e
VP
917Install the current binutils-20080624-2 as they work fine (the old
918binutils-20060709-1 proved buggy on shared builds).
d0e1cd3d 919
29c3d42b
VP
920Then create a small library that just contains llrint():
921
922@example
923ar x /usr/lib/mingw/libmingwex.a llrint.o
924ar cq /usr/local/lib/libllrint.a llrint.o
925@end example
926
d0e1cd3d
DB
927Then run
928
929@example
29c3d42b 930./configure --enable-static --disable-shared --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
931@end example
932
933to make a static build or
934
935@example
29c3d42b 936./configure --enable-shared --disable-static --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
937@end example
938
939to build shared libraries.
940
941If you want to build FFmpeg with additional libraries, download Cygwin
5dd9799d
VP
942"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
943@example
944libogg-devel, libvorbis-devel
945@end example
946
947These library packages are only available from Cygwin Ports
be8497b0 948(@url{http://sourceware.org/cygwinports/}) :
5dd9799d
VP
949
950@example
951yasm, libSDL-devel, libdirac-devel, libfaac-devel, libfaad-devel, libgsm-devel,
952libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
953libxvidcore-devel
954@end example
955
956The recommendation for libnut and x264 is to build them from source by
957yourself, as they evolve too quickly for Cygwin Ports to be up to date.
d0e1cd3d 958
cdf51395
VP
959Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
960of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
961
d0e1cd3d
DB
962@subsection Crosscompilation for Windows under Cygwin
963
964With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
965
966Just install your Cygwin as explained before, plus these additional
967"Devel" packages:
968@example
969gcc-mingw-core, mingw-runtime, mingw-zlib
970@end example
971
972and add some special flags to your configure invocation.
973
974For a static build run
975@example
976./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
977@end example
978
979and for a build with shared libraries
980@example
981./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
