@chapter external libraries
|
|
|
|
Libav can be hooked up with a number of external libraries to add support
|
|
for more formats. None of them are used by default, their use has to be
|
|
explicitly requested by passing the appropriate flags to @file{./configure}.
|
|
|
|
@section OpenCORE AMR
|
|
|
|
Libav can make use of the OpenCORE libraries for AMR-NB
|
|
decoding/encoding and AMR-WB decoding.
|
|
|
|
Go to @url{http://sourceforge.net/projects/opencore-amr/} and follow the instructions for
|
|
installing the libraries. Then pass @code{--enable-libopencore-amrnb} and/or
|
|
@code{--enable-libopencore-amrwb} to configure to enable the libraries.
|
|
|
|
Note that OpenCORE is under the Apache License 2.0 (see
|
|
@url{http://www.apache.org/licenses/LICENSE-2.0} for details), which is
|
|
incompatible with the LGPL version 2.1 and GPL version 2. You have to
|
|
upgrade Libav's license to LGPL version 3 (or if you have enabled
|
|
GPL components, GPL version 3) to use it.
|
|

|

@chapter Platform Specific information
|
|
|
|
@section DOS
|
|
|
|
Using a cross-compiler is preferred for various reasons.
|
|
|
|
@section OS/2
|
|
|
|
For information about compiling Libav on OS/2 see
|
|
@url{http://www.edm2.com/index.php/FFmpeg}.
|
|
|
|
@section Unix-like
|
|
|
|
Some parts of Libav cannot be built with version 2.15 of the GNU
|
|
assembler which is still provided by a few AMD64 distributions. To
|
|
make sure your compiler really uses the required version of gas
|
|
after a binutils upgrade, run:
|
|
|
|
@example
|
|
$(gcc -print-prog-name=as) --version
|
|
@end example
|
|
|
|
If not, then you should install a different compiler that has no
|
|
hard-coded path to gas. In the worst case pass @code{--disable-asm}
|
|
to configure.
|
|
|
|
@subsection BSD
|
|
|
|
BSD make will not build Libav, you need to install and use GNU Make
|
|
(@file{gmake}).
|
|
|
|
@subsection (Open)Solaris
|
|
|
|
GNU Make is required to build Libav, so you have to invoke (@file{gmake}),
|
|
standard Solaris Make will not work. When building with a non-c99 front-end
|
|
(gcc, generic suncc) add either @code{--extra-libs=/usr/lib/values-xpg6.o}
|
|
or @code{--extra-libs=/usr/lib/64/values-xpg6.o} to the configure options
|
|
since the libc is not c99-compliant by default. The probes performed by
|
|
configure may raise an exception leading to the death of configure itself
|
|
due to a bug in the system shell. Simply invoke a different shell such as
|
|
bash directly to work around this:
|
|
|
|
@example
|
|
bash ./configure
|
|
@end example
|
|
|
|
@subsection Darwin (MacOS X, iPhone)
|
|
|
|
MacOS X on PowerPC or ARM (iPhone) requires a preprocessor from
|
|
@url{http://github.com/yuvi/gas-preprocessor} to build the optimized
|
|
assembler functions. Just download the Perl script and put it somewhere
|
|
in your PATH, Libav's configure will pick it up automatically.
|
|
|
|
@section Windows
|
|
|
|
@subsection Native Windows compilation
|
|
|
|
Libav can be built to run natively on Windows using the MinGW tools. Install
|
|
the latest versions of MSYS and MinGW from @url{http://www.mingw.org/}.
|
|
You can find detailed installation
|
|
instructions in the download section and the FAQ.
|
|
|
|
Libav does not build out-of-the-box with the packages the automated MinGW
|
|
installer provides. It also requires coreutils to be installed and many other
|
|
packages updated to the latest version. The minimum version for some packages
|
|
are listed below:
|
|
|
|
@itemize
|
|
@item bash 3.1
|
|
@item msys-make 3.81-2 (note: not mingw32-make)
|
|
@item w32api 3.13
|
|
@item mingw-runtime 3.15
|
|
@end itemize
|
|
|
|
Libav automatically passes @code{-fno-common} to the compiler to work around
|
|
a GCC bug (see @url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216}).
|
|
|
|
Notes:
|
|
|
|
@itemize
|
|
|
|
@item Building natively using MSYS can be sped up by disabling implicit rules
|
|
in the Makefile by calling @code{make -r} instead of plain @code{make}. This
|
|
speed up is close to non-existent for normal one-off builds and is only
|
|
noticeable when running make for a second time (for example in
|
|
@code{make install}).
|
|
|
|
@item In order to compile AVplay, you must have the MinGW development library
|
|
of @uref{http://www.libsdl.org/, SDL}.
|
|
Edit the @file{bin/sdl-config} script so that it points to the correct prefix
|
|
where SDL was installed. Verify that @file{sdl-config} can be launched from
|
|
the MSYS command line.
|
|
|
|
@item By using @code{./configure --enable-shared} when configuring Libav,
|
|
you can build libavutil, libavcodec and libavformat as DLLs.
|
|
|
|
@end itemize
|
|
|
|
@subsection Microsoft Visual C++ compatibility
|
|
|
|
As stated in the FAQ, Libav will not compile under MSVC++. However, if you
|
|
want to use the libav* libraries in your own applications, you can still
|
|
compile those applications using MSVC++. But the libav* libraries you link
|
|
to @emph{must} be built with MinGW. However, you will not be able to debug
|
|
inside the libav* libraries, since MSVC++ does not recognize the debug
|
|
symbols generated by GCC.
|
|
We strongly recommend you to move over from MSVC++ to MinGW tools.
|
|
|
|
This description of how to use the Libav libraries with MSVC++ is based on
|
|
Microsoft Visual C++ 2005 Express Edition. If you have a different version,
|
|
you might have to modify the procedures slightly.
|
|
|
|
@subsubsection Using static libraries
|
|
|
|
Assuming you have just built and installed Libav in @file{/usr/local}.
|
|
|
|
@enumerate
|
|
|
|
@item Create a new console application ("File / New / Project") and then
|
|
select "Win32 Console Application". On the appropriate page of the
|
|
Application Wizard, uncheck the "Precompiled headers" option.
|
|
|
|
@item Write the source code for your application, or, for testing, just
|
|
copy the code from an existing sample application into the source file
|
|
that MSVC++ has already created for you. For example, you can copy
|
|
@file{libavformat/output-example.c} from the Libav distribution.
|
|
|
|
@item Open the "Project / Properties" dialog box. In the "Configuration"
|
|
combo box, select "All Configurations" so that the changes you make will
|
|
affect both debug and release builds. In the tree view on the left hand
|
|
side, select "C/C++ / General", then edit the "Additional Include
|
|
Directories" setting to contain the path where the Libav includes were
|
|
installed (i.e. @file{c:\msys\1.0\local\include}).
|
|
Do not add MinGW's include directory here, or the include files will
|
|
conflict with MSVC's.
|
|
|
|
@item Still in the "Project / Properties" dialog box, select
|
|
"Linker / General" from the tree view and edit the
|
|
"Additional Library Directories" setting to contain the @file{lib}
|
|
directory where Libav was installed (i.e. @file{c:\msys\1.0\local\lib}),
|
|
the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
|
|
and the directory where MinGW's GCC libs are installed
|
|
(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
|
|
"Linker / Input" from the tree view, and add the files @file{libavformat.a},
|
|
@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
|
|
@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
|
|
to the end of "Additional Dependencies".
|
|
|
|
@item Now, select "C/C++ / Code Generation" from the tree view. Select
|
|
"Debug" in the "Configuration" combo box. Make sure that "Runtime
|
|
Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
|
|
the "Configuration" combo box and make sure that "Runtime Library" is
|
|
set to "Multi-threaded DLL".
|
|
|
|
@item Click "OK" to close the "Project / Properties" dialog box.
|
|
|
|
@item MSVC++ lacks some C99 header files that are fundamental for Libav.
|
|
Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
|
|
and install it in MSVC++'s include directory
|
|
(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
|
|
|
|
@item MSVC++ also does not understand the @code{inline} keyword used by
|
|
Libav, so you must add this line before @code{#include}ing libav*:
|
|
@example
|
|
#define inline _inline
|
|
@end example
|
|
|
|
@item Build your application, everything should work.
|
|
|
|
@end enumerate
|
|
|
|
@subsubsection Using shared libraries
|
|
|
|
This is how to create DLL and LIB files that are compatible with MSVC++:
|
|
|
|
Within the MSYS shell, build Libav with
|
|
|
|
@example
|
|
./configure --enable-shared
|
|
make
|
|
make install
|
|
@end example
|
|
|
|
Your install path (@file{/usr/local/} by default) should now have the
|
|
necessary DLL and LIB files under the @file{bin} directory.
|
|
|
|
Alternatively, build the libraries with a cross compiler, according to
|
|
the instructions below in @ref{Cross compilation for Windows with Linux}.
|
|
|
|
To use those files with MSVC++, do the same as you would do with
|
|
the static libraries, as described above. But in Step 4,
|
|
you should only need to add the directory where the LIB files are installed
|
|
(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
|
|
installed in the @file{bin} directory. And instead of adding the static
|
|
libraries (@file{libxxx.a} files) you should add the MSVC import libraries
|
|
(@file{avcodec.lib}, @file{avformat.lib}, and
|
|
@file{avutil.lib}). Note that you should not use the GCC import
|
|
libraries (@file{libxxx.dll.a} files), as these will give you undefined
|
|
reference errors. There should be no need for @file{libmingwex.a},
|
|
@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
|
|
statically linked into the DLLs.
|
|
|
|
Libav headers do not declare global data for Windows DLLs through the usual
|
|
dllexport/dllimport interface. Such data will be exported properly while
|
|
building, but to use them in your MSVC++ code you will have to edit the
|
|
appropriate headers and mark the data as dllimport. For example, in
|
|
libavutil/pixdesc.h you should have:
|
|
@example
|
|
extern __declspec(dllimport) const AVPixFmtDescriptor av_pix_fmt_descriptors[];
|
|
@end example
|
|
|
|
Note that using import libraries created by dlltool requires
|
|
the linker optimization option to be set to
|
|
"References: Keep Unreferenced Data (@code{/OPT:NOREF})", otherwise
|
|
the resulting binaries will fail during runtime. This isn't
|
|
required when using import libraries generated by lib.exe.
|
|
This issue is reported upstream at
|
|
@url{http://sourceware.org/bugzilla/show_bug.cgi?id=12633}.
|
|
|
|
To create import libraries that work with the @code{/OPT:REF} option
|
|
(which is enabled by default in Release mode), follow these steps:
|
|
|
|
@enumerate
|
|
|
|
@item Open @file{Visual Studio 2005 Command Prompt}.
|
|
|
|
Alternatively, in a normal command line prompt, call @file{vcvars32.bat}
|
|
which sets up the environment variables for the Visual C++ tools
|
|
(the standard location for this file is
|
|
@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat}).
|
|
|
|
@item Enter the @file{bin} directory where the created LIB and DLL files
|
|
are stored.
|
|
|
|
@item Generate new import libraries with @file{lib.exe}:
|
|
|
|
@example
|
|
lib /machine:i386 /def:..\lib\avcodec-53.def /out:avcodec.lib
|
|
lib /machine:i386 /def:..\lib\avdevice-53.def /out:avdevice.lib
|
|
lib /machine:i386 /def:..\lib\avfilter-2.def /out:avfilter.lib
|
|
lib /machine:i386 /def:..\lib\avformat-53.def /out:avformat.lib
|
|
lib /machine:i386 /def:..\lib\avutil-51.def /out:avutil.lib
|
|
lib /machine:i386 /def:..\lib\swscale-2.def /out:swscale.lib
|
|
@end example
|
|
|
|
@end enumerate
|
|
|
|
@anchor{Cross compilation for Windows with Linux}
|
|
@subsection Cross compilation for Windows with Linux
|
|
|
|
You must use the MinGW cross compilation tools available at
|
|
@url{http://www.mingw.org/}.
|
|
|
|
Then configure Libav with the following options:
|
|
@example
|
|
./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
|
|
@end example
|
|
(you can change the cross-prefix according to the prefix chosen for the
|
|
MinGW tools).
|
|
|
|
Then you can easily test Libav with @uref{http://www.winehq.com/, Wine}.
|
|
|
|
@subsection Compilation under Cygwin
|
|
|
|
Please use Cygwin 1.7.x as the obsolete 1.5.x Cygwin versions lack
|
|
llrint() in its C library.
|
|
|
|
Install your Cygwin with all the "Base" packages, plus the
|
|
following "Devel" ones:
|
|
@example
|
|
binutils, gcc4-core, make, git, mingw-runtime, texi2html
|
|
@end example
|
|
|
|
And the following "Utils" one:
|
|
@example
|
|
diffutils
|
|
@end example
|
|
|
|
Then run
|
|
|
|
@example
|
|
./configure
|
|
@end example
|
|
|
|
to make a static build.
|
|
|
|
The current @code{gcc4-core} package is buggy and needs this flag to build
|
|
shared libraries:
|
|
|
|
@example
|
|
./configure --enable-shared --disable-static --extra-cflags=-fno-reorder-functions
|
|
@end example
|
|
|
|
If you want to build Libav with additional libraries, download Cygwin
|
|
"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
|
|
@example
|
|
libogg-devel, libvorbis-devel
|
|
@end example
|
|
|
|
These library packages are only available from
|
|
@uref{http://sourceware.org/cygwinports/, Cygwin Ports}:
|
|
|
|
@example
|
|
yasm, libSDL-devel, libdirac-devel, libfaac-devel, libgsm-devel,
|
|
libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
|
|
libxvidcore-devel
|
|
@end example
|
|
|
|
The recommendation for libnut and x264 is to build them from source by
|
|
yourself, as they evolve too quickly for Cygwin Ports to be up to date.
|
|
|
|
Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
|
|
of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
|
|
|
|
@subsection Crosscompilation for Windows under Cygwin
|
|
|
|
With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
|
|
|
|
Just install your Cygwin as explained before, plus these additional
|
|
"Devel" packages:
|
|
@example
|
|
gcc-mingw-core, mingw-runtime, mingw-zlib
|
|
@end example
|
|
|
|
and add some special flags to your configure invocation.
|
|
|
|
For a static build run
|
|
@example
|
|
./configure --target-os=mingw32 --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
|
|
@end example
|
|
|
|
and for a build with shared libraries
|
|
@example
|
|
./configure --target-os=mingw32 --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
|
|
@end example
|
|
|
|
@bye
