765@item Building natively using MSYS can be sped up by disabling implicit rules
766in the Makefile by calling @code{make -r} instead of plain @code{make}. This
767speed up is close to non-existent for normal one-off builds and is only
768noticeable when running make for a second time (for example in
769@code{make install}).

771@item In order to compile FFplay, you must have the MinGW development library
772of SDL. Get it from @url{http://www.libsdl.org}.
773Edit the @file{bin/sdl-config} script so that it points to the correct prefix
774where SDL was installed. Verify that @file{sdl-config} can be launched from
775the MSYS command line.
d0e1cd3d 776
d0e1cd3d 777@item By using @code{./configure --enable-shared} when configuring FFmpeg,
c1989552 778you can build libavutil, libavcodec and libavformat as DLLs.

784As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
785want to use the libav* libraries in your own applications, you can still
786compile those applications using MSVC++. But the libav* libraries you link
787to @emph{must} be built with MinGW. However, you will not be able to debug
788inside the libav* libraries, since MSVC++ does not recognize the debug
789symbols generated by GCC.
790We strongly recommend you to move over from MSVC++ to MinGW tools.
d0e1cd3d 791
c1989552
RP
792This description of how to use the FFmpeg libraries with MSVC++ is based on
793Microsoft Visual C++ 2005 Express Edition. If you have a different version,
794you might have to modify the procedures slightly.
d0e1cd3d 795
c1989552 796@subsubsection Using static libraries
d0e1cd3d 797
c1989552 798Assuming you have just built and installed FFmpeg in @file{/usr/local}.
d0e1cd3d
DB
799
800@enumerate
801
802@item Create a new console application ("File / New / Project") and then
803select "Win32 Console Application". On the appropriate page of the
804Application Wizard, uncheck the "Precompiled headers" option.
805
806@item Write the source code for your application, or, for testing, just
807copy the code from an existing sample application into the source file
c1989552 808that MSVC++ has already created for you. For example, you can copy
d95a0c67 809@file{libavformat/output-example.c} from the FFmpeg distribution.
d0e1cd3d
DB
810
811@item Open the "Project / Properties" dialog box. In the "Configuration"
812combo box, select "All Configurations" so that the changes you make will
813affect both debug and release builds. In the tree view on the left hand
814side, select "C/C++ / General", then edit the "Additional Include
c1989552
RP
815Directories" setting to contain the path where the FFmpeg includes were
816installed (i.e. @file{c:\msys\1.0\local\include}).
f010d377
RP
817Do not add MinGW's include directory here, or the include files will
818conflict with MSVC's.
c1989552
RP
819
820@item Still in the "Project / Properties" dialog box, select
821"Linker / General" from the tree view and edit the
822"Additional Library Directories" setting to contain the @file{lib}
823directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
824the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
825and the directory where MinGW's GCC libs are installed
826(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
827"Linker / Input" from the tree view, and add the files @file{libavformat.a},
828@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
829@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
830to the end of "Additional Dependencies".
d0e1cd3d
DB
831
832@item Now, select "C/C++ / Code Generation" from the tree view. Select
833"Debug" in the "Configuration" combo box. Make sure that "Runtime
834Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
835the "Configuration" combo box and make sure that "Runtime Library" is
836set to "Multi-threaded DLL".
837
c1989552
RP
838@item Click "OK" to close the "Project / Properties" dialog box.
839
840@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
841Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
842and install it in MSVC++'s include directory
843(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
844
845@item MSVC++ also does not understand the @code{inline} keyword used by
846FFmpeg, so you must add this line before @code{#include}ing libav*:
847@example
848#define inline _inline
849@end example
850
c1989552
RP
851@item Build your application, everything should work.
852
853@end enumerate
854
855@subsubsection Using shared libraries
856
857This is how to create DLL and LIB files that are compatible with MSVC++:
858
859@enumerate
860
861@item Add a call to @file{vcvars32.bat} (which sets up the environment
862variables for the Visual C++ tools) as the first line of @file{msys.bat}.
863The standard location for @file{vcvars32.bat} is
864@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
865and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
866If this corresponds to your setup, add the following line as the first line
867of @file{msys.bat}:
868
869@example
870call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
871@end example
872
873Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
874and run @file{c:\msys\1.0\msys.bat} from there.
875
876@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
877from @file{Microsoft (R) Library Manager}, this means your environment
878variables are set up correctly, the @file{Microsoft (R) Library Manager}
879is on the path and will be used by FFmpeg to create
880MSVC++-compatible import libraries.
881
882@item Build FFmpeg with
883
884@example
885./configure --enable-shared --enable-memalign-hack
886make
887make install
888@end example
889
890Your install path (@file{/usr/local/} by default) should now have the
891necessary DLL and LIB files under the @file{bin} directory.
d0e1cd3d
DB
892
893@end enumerate
894
c1989552
RP
895To use those files with MSVC++, do the same as you would do with
896the static libraries, as described above. But in Step 4,
897you should only need to add the directory where the LIB files are installed
898(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
899installed in the @file{bin} directory. And instead of adding @file{libxx.a}
900files, you should add @file{avcodec.lib}, @file{avformat.lib}, and
901@file{avutil.lib}. There should be no need for @file{libmingwex.a},
902@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
903statically linked into the DLLs. The @file{bin} directory contains a bunch
904of DLL files, but the ones that are actually used to run your application
905are the ones with a major version number in their filenames
906(i.e. @file{avcodec-51.dll}).
907
d0e1cd3d
DB
908@subsection Cross compilation for Windows with Linux
909
910You must use the MinGW cross compilation tools available at
911@url{http://www.mingw.org/}.
912
913Then configure FFmpeg with the following options:
914@example
915./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
916@end example
917(you can change the cross-prefix according to the prefix chosen for the
918MinGW tools).
919
920Then you can easily test FFmpeg with Wine
921(@url{http://www.winehq.com/}).
922
923@subsection Compilation under Cygwin
924
8484503e
VP
925The main issue with the 1.5.x Cygwin versions is that newlib, its C library,
926does not contain llrint(). You need to upgrade to the unstable 1.7.x versions,
927or leverage the implementation in MinGW (as explained below).
d0e1cd3d
DB
928
929Just install your Cygwin with all the "Base" packages, plus the
930following "Devel" ones:
931@example
71ecc16b
RP
932binutils, gcc-core, make, subversion, mingw-runtime
933@end example
934
935And the following "Utils" one:
936@example
937diffutils
d0e1cd3d
DB
938@end example
939
666a1b34
VP
940The experimental gcc4 package is still buggy, hence please
941use the official gcc 3.4.4 or a 4.2.x compiled from source by yourself.
942
8484503e
VP
943Install the current binutils-20080624-2 as they work fine (the old
944binutils-20060709-1 proved buggy on shared builds).
d0e1cd3d 945
29c3d42b
VP
946Then create a small library that just contains llrint():
947
948@example
949ar x /usr/lib/mingw/libmingwex.a llrint.o
950ar cq /usr/local/lib/libllrint.a llrint.o
951@end example
952
d0e1cd3d
DB
953Then run
954
955@example
29c3d42b 956./configure --enable-static --disable-shared --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
957@end example
958
959to make a static build or
960
961@example
29c3d42b 962./configure --enable-shared --disable-static --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
963@end example
964
965to build shared libraries.
966
967If you want to build FFmpeg with additional libraries, download Cygwin
5dd9799d
VP
968"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
969@example
970libogg-devel, libvorbis-devel
971@end example
972
973These library packages are only available from Cygwin Ports
be8497b0 974(@url{http://sourceware.org/cygwinports/}) :
5dd9799d
VP
975
976@example
977yasm, libSDL-devel, libdirac-devel, libfaac-devel, libfaad-devel, libgsm-devel,
978libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
979libxvidcore-devel
980@end example
981
982The recommendation for libnut and x264 is to build them from source by
983yourself, as they evolve too quickly for Cygwin Ports to be up to date.
d0e1cd3d 984

VP
985Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
986of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
987
d0e1cd3d
DB
988@subsection Crosscompilation for Windows under Cygwin
989
990With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
991
992Just install your Cygwin as explained before, plus these additional
993"Devel" packages:
994@example
995gcc-mingw-core, mingw-runtime, mingw-zlib
996@end example
997
998and add some special flags to your configure invocation.
999
1000For a static build run
1001@example
1002./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
1003@end example
1004
1005and for a build with shared libraries
1006@example
1007./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
