General Documentation

FFmpeg 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 `./configure'.

AMR comes in two different flavors, wideband and narrowband. FFmpeg can make use of the AMR wideband (floating-point mode) and the AMR narrowband (floating-point mode) reference decoders and encoders (libamr) as well as the OpenCORE libraries for AMR-NB decoding/encoding and AMR-WB decoding.

Go to and follow the instructions for installing the libraries. Then pass

--enable-libopencore-amrnb

and/or

--enable-libopencore-amrwb

to configure to enable the libraries.

Note that OpenCORE is under the Apache License 2.0 (see for details), which is incompatible with the LGPL version 2.1 and GPL version 2. You have to upgrade FFmpeg's license to LGPL version 3 (or if you have enabled GPL components, GPL version 3) to use it.

Go to and follow the instructions for installing the libraries. Then pass

--enable-libamr-nb

and/or

--enable-libamr-wb

to configure to enable the libraries.

Note that libamr is copyrighted without any sort of license grant. This means that you can use it if you legally obtained it but you are not allowed to redistribute it in any way. Any FFmpeg binaries with libamr support you create are non-free and unredistributable!

You can use the

-formats

option to have an exhaustive list.

BSD make will not build FFmpeg, you need to install and use GNU Make (`gmake').

To get help and instructions for building FFmpeg under Windows, check out the FFmpeg Windows Help Forum at .

FFmpeg can be built to run natively on Windows using the MinGW tools. Install the latest versions of MSYS and MinGW from . You can find detailed installation instructions in the download section and the FAQ.

FFmpeg 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:

• bash 3.1
• msys-make 3.81-2 (note: not mingw32-make)
• w32api 3.13
• mingw-runtime 3.15

FFmpeg automatically passes

-fno-common

to the compiler to work around a GCC bug (see ).

Within the MSYS shell, configure and make with:

./configure --enable-memalign-hack --extra-cflags=-fno-commonmakemake install

This will install `ffmpeg.exe' along with many other development files to `/usr/local'. You may specify another install path using the

--prefix

option in `configure'.

Notes:

• In order to compile FFplay, you must have the MinGW development library of SDL. Get it from . Edit the `bin/sdl-config' script so that it points to the correct prefix where SDL was installed. Verify that `sdl-config' can be launched from the MSYS command line.
• By using

  ./configure --enable-shared

  when configuring FFmpeg, you can build libavutil, libavcodec and libavformat as DLLs.

As stated in the FAQ, FFmpeg 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 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 FFmpeg 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.

Assuming you have just built and installed FFmpeg in `/usr/local'.

1. 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.
2. 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 `libavformat/output-example.c' from the FFmpeg distribution.
3. 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 FFmpeg includes were installed (i.e. `c:\msys\1.0\local\include'). Do not add MinGW's include directory here, or the include files will conflict with MSVC's.
4. Still in the "Project / Properties" dialog box, select "Linker / General" from the tree view and edit the "Additional Library Directories" setting to contain the `lib' directory where FFmpeg was installed (i.e. `c:\msys\1.0\local\lib'), the directory where MinGW libs are installed (i.e. `c:\mingw\lib'), and the directory where MinGW's GCC libs are installed (i.e. `C:\mingw\lib\gcc\mingw32\4.2.1-sjlj'). Then select "Linker / Input" from the tree view, and add the files `libavformat.a', `libavcodec.a', `libavutil.a', `libmingwex.a', `libgcc.a', and any other libraries you used (i.e. `libz.a') to the end of "Additional Dependencies".
5. 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".
6. Click "OK" to close the "Project / Properties" dialog box.
7. MSVC++ lacks some C99 header files that are fundamental for FFmpeg. Get msinttypes from and install it in MSVC++'s include directory (i.e. `C:\Program Files\Microsoft Visual Studio 8\VC\include').
8. MSVC++ also does not understand the

   inline

   keyword used by FFmpeg, so you must add this line before

   #include

   ing libav*:

   #define inline _inline

9. Build your application, everything should work.

This is how to create DLL and LIB files that are compatible with MSVC++:

1. Add a call to `vcvars32.bat' (which sets up the environment variables for the Visual C++ tools) as the first line of `msys.bat'. The standard location for `vcvars32.bat' is `C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat', and the standard location for `msys.bat' is `C:\msys\1.0\msys.bat'. If this corresponds to your setup, add the following line as the first line of `msys.bat':

   call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"Alternatively, you may start the `Visual Studio 2005 Command Prompt', and run `c:\msys\1.0\msys.bat' from there.

2. Within the MSYS shell, run

   lib.exe

   . If you get a help message from `Microsoft (R) Library Manager', this means your environment variables are set up correctly, the `Microsoft (R) Library Manager' is on the path and will be used by FFmpeg to create MSVC++-compatible import libraries.

3. Build FFmpeg with

   ./configure --enable-shared --enable-memalign-hackmakemake installYour install path (`/usr/local/' by default) should now have the necessary DLL and LIB files under the `bin' directory.

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. `c:\msys\usr\local\bin'). This is not a typo, the LIB files are installed in the `bin' directory. And instead of adding `libxx.a' files, you should add `avcodec.lib', `avformat.lib', and `avutil.lib'. There should be no need for `libmingwex.a', `libgcc.a', and `wsock32.lib', nor any other external library statically linked into the DLLs. The `bin' directory contains a bunch of DLL files, but the ones that are actually used to run your application are the ones with a major version number in their filenames (i.e. `avcodec-51.dll').

You must use the MinGW cross compilation tools available at .

Then configure FFmpeg with the following options:

./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-

(you can change the cross-prefix according to the prefix chosen for the MinGW tools).

Then you can easily test FFmpeg with Wine ().

The main issue with the 1.5.x Cygwin versions is that newlib, its C library, does not contain llrint(). You need to upgrade to the unstable 1.7.x versions, or leverage the implementation in MinGW (as explained below).

Just install your Cygwin with all the "Base" packages, plus the following "Devel" ones:

binutils, gcc-core, make, subversion, mingw-runtime, diffutils

The experimental gcc4 package is still buggy, hence please use the official gcc 3.4.4 or a 4.2.x compiled from source by yourself.

Install the current binutils-20080624-2 as they work fine (the old binutils-20060709-1 proved buggy on shared builds).

Then create a small library that just contains llrint():

ar x /usr/lib/mingw/libmingwex.a llrint.oar cq /usr/local/lib/libllrint.a llrint.o

Then run

./configure --enable-static --disable-shared --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'

to make a static build or

./configure --enable-shared --disable-static --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint'

to build shared libraries.

If you want to build FFmpeg with additional libraries, download Cygwin "Devel" packages for Ogg and Vorbis from any Cygwin packages repository:

libogg-devel, libvorbis-devel

These library packages are only available from Cygwin Ports () :

yasm, libSDL-devel, libdirac-devel, libfaac-devel, libfaad-devel, libgsm-devel,libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,libxvidcore-devel

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

libgetaddrinfo-devel

package, available at Cygwin Ports.

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:

gcc-mingw-core, mingw-runtime, mingw-zlib

and add some special flags to your configure invocation.

For a static build run

./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin

and for a build with shared libraries

./configure --target-os=mingw32 --enable-memalign-hack --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin

BeOS support is broken in mysterious ways.
