750@item Building natively using MSYS can be sped up by disabling implicit rules
751in the Makefile by calling @code{make -r} instead of plain @code{make}. This
752speed up is close to non-existent for normal one-off builds and is only
753noticeable when running make for a second time (for example in
754@code{make install}).

756@item In order to compile FFplay, you must have the MinGW development library
757of SDL. Get it from @url{http://www.libsdl.org}.
758Edit the @file{bin/sdl-config} script so that it points to the correct prefix
759where SDL was installed. Verify that @file{sdl-config} can be launched from
760the MSYS command line.
d0e1cd3d 761
d0e1cd3d 762@item By using @code{./configure --enable-shared} when configuring FFmpeg,
c1989552 763you can build libavutil, libavcodec and libavformat as DLLs.

769As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
770want to use the libav* libraries in your own applications, you can still
771compile those applications using MSVC++. But the libav* libraries you link
772to @emph{must} be built with MinGW. However, you will not be able to debug
773inside the libav* libraries, since MSVC++ does not recognize the debug
774symbols generated by GCC.
775We strongly recommend you to move over from MSVC++ to MinGW tools.
d0e1cd3d 776

777This description of how to use the FFmpeg libraries with MSVC++ is based on
778Microsoft Visual C++ 2005 Express Edition. If you have a different version,
779you might have to modify the procedures slightly.
d0e1cd3d 780
c1989552 781@subsubsection Using static libraries
d0e1cd3d 782
c1989552 783Assuming you have just built and installed FFmpeg in @file{/usr/local}.
d0e1cd3d
DB
784
785@enumerate
786
787@item Create a new console application ("File / New / Project") and then
788select "Win32 Console Application". On the appropriate page of the
789Application Wizard, uncheck the "Precompiled headers" option.
790
791@item Write the source code for your application, or, for testing, just
792copy the code from an existing sample application into the source file
c1989552 793that MSVC++ has already created for you. For example, you can copy
d95a0c67 794@file{libavformat/output-example.c} from the FFmpeg distribution.
d0e1cd3d
DB
795
796@item Open the "Project / Properties" dialog box. In the "Configuration"
797combo box, select "All Configurations" so that the changes you make will
798affect both debug and release builds. In the tree view on the left hand
799side, select "C/C++ / General", then edit the "Additional Include
c1989552
RP
800Directories" setting to contain the path where the FFmpeg includes were
801installed (i.e. @file{c:\msys\1.0\local\include}).
f010d377
RP
802Do not add MinGW's include directory here, or the include files will
803conflict with MSVC's.
c1989552
RP
804
805@item Still in the "Project / Properties" dialog box, select
806"Linker / General" from the tree view and edit the
807"Additional Library Directories" setting to contain the @file{lib}
808directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
809the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
810and the directory where MinGW's GCC libs are installed
811(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
812"Linker / Input" from the tree view, and add the files @file{libavformat.a},
813@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
814@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
815to the end of "Additional Dependencies".
d0e1cd3d
DB
816
817@item Now, select "C/C++ / Code Generation" from the tree view. Select
818"Debug" in the "Configuration" combo box. Make sure that "Runtime
819Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
820the "Configuration" combo box and make sure that "Runtime Library" is
821set to "Multi-threaded DLL".
822
c1989552
RP
823@item Click "OK" to close the "Project / Properties" dialog box.
824
825@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
826Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
827and install it in MSVC++'s include directory
828(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
829
830@item MSVC++ also does not understand the @code{inline} keyword used by
831FFmpeg, so you must add this line before @code{#include}ing libav*:
832@example
833#define inline _inline
834@end example
835
c1989552
RP
836@item Build your application, everything should work.
837
838@end enumerate
839
840@subsubsection Using shared libraries
841
842This is how to create DLL and LIB files that are compatible with MSVC++:
843
844@enumerate
845
846@item Add a call to @file{vcvars32.bat} (which sets up the environment
847variables for the Visual C++ tools) as the first line of @file{msys.bat}.
848The standard location for @file{vcvars32.bat} is
849@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
850and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
851If this corresponds to your setup, add the following line as the first line
852of @file{msys.bat}:
853
854@example
855call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
856@end example
857
858Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
859and run @file{c:\msys\1.0\msys.bat} from there.
860
861@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
862from @file{Microsoft (R) Library Manager}, this means your environment
863variables are set up correctly, the @file{Microsoft (R) Library Manager}
864is on the path and will be used by FFmpeg to create
865MSVC++-compatible import libraries.
866
867@item Build FFmpeg with
868
869@example
870./configure --enable-shared --enable-memalign-hack
871make
872make install
873@end example
874
875Your install path (@file{/usr/local/} by default) should now have the
876necessary DLL and LIB files under the @file{bin} directory.
d0e1cd3d
DB
877
878@end enumerate
879
c1989552
RP
880To use those files with MSVC++, do the same as you would do with
881the static libraries, as described above. But in Step 4,
882you should only need to add the directory where the LIB files are installed
883(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
884installed in the @file{bin} directory. And instead of adding @file{libxx.a}
885files, you should add @file{avcodec.lib}, @file{avformat.lib}, and
886@file{avutil.lib}. There should be no need for @file{libmingwex.a},
887@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
888statically linked into the DLLs. The @file{bin} directory contains a bunch
889of DLL files, but the ones that are actually used to run your application
890are the ones with a major version number in their filenames
891(i.e. @file{avcodec-51.dll}).
892
d0e1cd3d
DB
893@subsection Cross compilation for Windows with Linux
894
895You must use the MinGW cross compilation tools available at
896@url{http://www.mingw.org/}.
897
898Then configure FFmpeg with the following options:
899@example
900./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
901@end example
902(you can change the cross-prefix according to the prefix chosen for the
903MinGW tools).
904
905Then you can easily test FFmpeg with Wine
906(@url{http://www.winehq.com/}).
907
908@subsection Compilation under Cygwin
909
8484503e
VP
910The main issue with the 1.5.x Cygwin versions is that newlib, its C library,
911does not contain llrint(). You need to upgrade to the unstable 1.7.x versions,
912or leverage the implementation in MinGW (as explained below).
d0e1cd3d
DB
913
914Just install your Cygwin with all the "Base" packages, plus the
915following "Devel" ones:
916@example
71ecc16b
RP
917binutils, gcc-core, make, subversion, mingw-runtime
918@end example
919
920And the following "Utils" one:
921@example
922diffutils
d0e1cd3d
DB
923@end example
924
666a1b34
VP
925The experimental gcc4 package is still buggy, hence please
926use the official gcc 3.4.4 or a 4.2.x compiled from source by yourself.
927
8484503e
VP
928Install the current binutils-20080624-2 as they work fine (the old
929binutils-20060709-1 proved buggy on shared builds).
d0e1cd3d 930
29c3d42b
VP
931Then create a small library that just contains llrint():
932
933@example
934ar x /usr/lib/mingw/libmingwex.a llrint.o
935ar cq /usr/local/lib/libllrint.a llrint.o
936@end example
937
d0e1cd3d
DB
938Then run
939
940@example
29c3d42b 941./configure --enable-static --disable-shared --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
942@end example
943
944to make a static build or
945
946@example
29c3d42b 947./configure --enable-shared --disable-static --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'
d0e1cd3d
DB
948@end example
949
950to build shared libraries.
951
952If you want to build FFmpeg with additional libraries, download Cygwin
5dd9799d
VP
953"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
954@example
955libogg-devel, libvorbis-devel
956@end example
957
958These library packages are only available from Cygwin Ports
be8497b0 959(@url{http://sourceware.org/cygwinports/}) :
5dd9799d
VP
960
961@example
962yasm, libSDL-devel, libdirac-devel, libfaac-devel, libfaad-devel, libgsm-devel,
963libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
964libxvidcore-devel
965@end example
966
967The recommendation for libnut and x264 is to build them from source by
968yourself, as they evolve too quickly for Cygwin Ports to be up to date.
d0e1cd3d 969

970Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
971of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.

973@subsection Crosscompilation for Windows under Cygwin
974
975With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
976
977Just install your Cygwin as explained before, plus these additional
978"Devel" packages:
979@example
980gcc-mingw-core, mingw-runtime, mingw-zlib
981@end example
982
983and add some special flags to your configure invocation.
984
985For a static build run
986@example
987./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
988@end example
989
990and for a build with shared libraries
991@example
992./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
