748of SDL. Get it from @url{http://www.libsdl.org}.
749Edit the @file{bin/sdl-config} script so that it points to the correct prefix
750where SDL was installed. Verify that @file{sdl-config} can be launched from

760As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
761want to use the libav* libraries in your own applications, you can still
762compile those applications using MSVC++. But the libav* libraries you link
763to @emph{must} be built with MinGW. However, you will not be able to debug
764inside the libav* libraries, since MSVC++ does not recognize the debug
765symbols generated by GCC.
766We strongly recommend you to move over from MSVC++ to MinGW tools.

768This description of how to use the FFmpeg libraries with MSVC++ is based on
769Microsoft Visual C++ 2005 Express Edition. If you have a different version,
770you might have to modify the procedures slightly.
d0e1cd3d 771
c1989552 772@subsubsection Using static libraries
d0e1cd3d 773
c1989552 774Assuming you have just built and installed FFmpeg in @file{/usr/local}.
d0e1cd3d
DB
775
776@enumerate
777
778@item Create a new console application ("File / New / Project") and then
779select "Win32 Console Application". On the appropriate page of the
780Application Wizard, uncheck the "Precompiled headers" option.
781
782@item Write the source code for your application, or, for testing, just
783copy the code from an existing sample application into the source file
c1989552 784that MSVC++ has already created for you. For example, you can copy
d95a0c67 785@file{libavformat/output-example.c} from the FFmpeg distribution.
d0e1cd3d
DB
786
787@item Open the "Project / Properties" dialog box. In the "Configuration"
788combo box, select "All Configurations" so that the changes you make will
789affect both debug and release builds. In the tree view on the left hand
790side, select "C/C++ / General", then edit the "Additional Include
c1989552
RP
791Directories" setting to contain the path where the FFmpeg includes were
792installed (i.e. @file{c:\msys\1.0\local\include}).
f010d377
RP
793Do not add MinGW's include directory here, or the include files will
794conflict with MSVC's.
c1989552
RP
795
796@item Still in the "Project / Properties" dialog box, select
797"Linker / General" from the tree view and edit the
798"Additional Library Directories" setting to contain the @file{lib}
799directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
800the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
801and the directory where MinGW's GCC libs are installed
802(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
803"Linker / Input" from the tree view, and add the files @file{libavformat.a},
804@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
805@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
806to the end of "Additional Dependencies".
d0e1cd3d
DB
807
808@item Now, select "C/C++ / Code Generation" from the tree view. Select
809"Debug" in the "Configuration" combo box. Make sure that "Runtime
810Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
811the "Configuration" combo box and make sure that "Runtime Library" is
812set to "Multi-threaded DLL".
813
c1989552
RP
814@item Click "OK" to close the "Project / Properties" dialog box.
815
816@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
817Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
818and install it in MSVC++'s include directory
819(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
820
821@item MSVC++ also does not understand the @code{inline} keyword used by
822FFmpeg, so you must add this line before @code{#include}ing libav*:
823@example
824#define inline _inline
825@end example
826
c1989552
RP
827@item Build your application, everything should work.
828
829@end enumerate
830
831@subsubsection Using shared libraries
832
833This is how to create DLL and LIB files that are compatible with MSVC++:
834
835@enumerate
836
837@item Add a call to @file{vcvars32.bat} (which sets up the environment
838variables for the Visual C++ tools) as the first line of @file{msys.bat}.
839The standard location for @file{vcvars32.bat} is
840@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
841and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
842If this corresponds to your setup, add the following line as the first line
843of @file{msys.bat}:
844
845@example
846call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
847@end example
848
849Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
850and run @file{c:\msys\1.0\msys.bat} from there.
851
852@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
853from @file{Microsoft (R) Library Manager}, this means your environment
854variables are set up correctly, the @file{Microsoft (R) Library Manager}
855is on the path and will be used by FFmpeg to create
856MSVC++-compatible import libraries.
857
858@item Build FFmpeg with
859
860@example
861./configure --enable-shared --enable-memalign-hack
862make
863make install
864@end example
865
866Your install path (@file{/usr/local/} by default) should now have the
867necessary DLL and LIB files under the @file{bin} directory.
d0e1cd3d
DB
868
869@end enumerate
870
c1989552
RP
871To use those files with MSVC++, do the same as you would do with
872the static libraries, as described above. But in Step 4,
873you should only need to add the directory where the LIB files are installed
874(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
875installed in the @file{bin} directory. And instead of adding @file{libxx.a}
876files, you should add @file{avcodec.lib}, @file{avformat.lib}, and
877@file{avutil.lib}. There should be no need for @file{libmingwex.a},
878@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
879statically linked into the DLLs. The @file{bin} directory contains a bunch
880of DLL files, but the ones that are actually used to run your application
881are the ones with a major version number in their filenames
882(i.e. @file{avcodec-51.dll}).
883
d0e1cd3d
DB
884@subsection Cross compilation for Windows with Linux
885
886You must use the MinGW cross compilation tools available at
887@url{http://www.mingw.org/}.
888
889Then configure FFmpeg with the following options:
890@example
891./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
892@end example
893(you can change the cross-prefix according to the prefix chosen for the
894MinGW tools).
895
896Then you can easily test FFmpeg with Wine
897(@url{http://www.winehq.com/}).
898
899@subsection Compilation under Cygwin
900
8484503e
VP
901The main issue with the 1.5.x Cygwin versions is that newlib, its C library,
902does not contain llrint(). You need to upgrade to the unstable 1.7.x versions,
903or leverage the implementation in MinGW (as explained below).
d0e1cd3d
DB
904
905Just install your Cygwin with all the "Base" packages, plus the
906following "Devel" ones:
907@example
71ecc16b
RP
908binutils, gcc-core, make, subversion, mingw-runtime
909@end example
910
911And the following "Utils" one:
912@example
913diffutils
d0e1cd3d
DB
914@end example
915
666a1b34
VP
916The experimental gcc4 package is still buggy, hence please
917use the official gcc 3.4.4 or a 4.2.x compiled from source by yourself.
918
8484503e
VP
919Install the current binutils-20080624-2 as they work fine (the old
920binutils-20060709-1 proved buggy on shared builds).
d0e1cd3d 921
29c3d42b
VP
922Then create a small library that just contains llrint():
923
924@example
925ar x /usr/lib/mingw/libmingwex.a llrint.o
926ar cq /usr/local/lib/libllrint.a llrint.o
927@end example
928
d0e1cd3d
DB
929Then run
930
931@example
29c3d42b 932./configure --enable-static --disable-shared --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
933@end example
934
935to make a static build or
936
937@example
29c3d42b 938./configure --enable-shared --disable-static --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
939@end example
940
941to build shared libraries.
942
943If you want to build FFmpeg with additional libraries, download Cygwin
5dd9799d
VP
944"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
945@example
946libogg-devel, libvorbis-devel
947@end example
948
949These library packages are only available from Cygwin Ports
be8497b0 950(@url{http://sourceware.org/cygwinports/}) :
5dd9799d
VP
951
952@example
953yasm, libSDL-devel, libdirac-devel, libfaac-devel, libfaad-devel, libgsm-devel,
954libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
955libxvidcore-devel
956@end example
957
958The recommendation for libnut and x264 is to build them from source by
959yourself, as they evolve too quickly for Cygwin Ports to be up to date.
d0e1cd3d 960

961Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
962of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.

964@subsection Crosscompilation for Windows under Cygwin
965
966With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
967
968Just install your Cygwin as explained before, plus these additional
969"Devel" packages:
970@example
971gcc-mingw-core, mingw-runtime, mingw-zlib
972@end example
973
974and add some special flags to your configure invocation.
975
976For a static build run
977@example
978./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
979@end example
980
981and for a build with shared libraries
982@example
983./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
