external libraries
******************

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.

OpenCORE AMR
============

FFmpeg can make use of the OpenCORE libraries for AMR-NB decoding/encoding and AMR-WB decoding.

Go to http://sourceforge.net/projects/opencore-amr/ 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 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 FFmpeg's license to LGPL version 3 (or if you have enabled GPL components, GPL version 3) to use it.

Platform Specific information
*****************************

BSD
===

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

Windows
=======

To get help and instructions for building FFmpeg under Windows, check out the FFmpeg Windows Help Forum at http://ffmpeg.arrozcru.org/.

Native Windows compilation
--------------------------

FFmpeg can be built to run natively on Windows using the MinGW tools. Install the latest versions of MSYS and MinGW from http://www.mingw.org/. 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 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216).

Within the MSYS shell, configure and make with:

     ./configure --enable-memalign-hack
     make
     make 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:

  * Building natively using MSYS can be sped up by disabling implicit rules in the Makefile by calling make -r instead of plain 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 make install).

  * In order to compile FFplay, you must have the MinGW development library of SDL. Get it from http://www.libsdl.org. 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.

Microsoft Visual C++ compatibility
----------------------------------

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.

Using static libraries
......................

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 http://code.google.com/p/msinttypes/downloads/list 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 #includeing libav*:

          #define inline _inline

 9. Build your application, everything should work.

Using shared libraries
......................

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-hack
          make
          make install

     Your 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).

Cross compilation for Windows with Linux
----------------------------------------

You must use the MinGW cross compilation tools available at http://www.mingw.org/.

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 (http://www.winehq.com/).

Compilation under Cygwin
------------------------

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

And the following "Utils" one:

     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.o
     ar 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 (http://sourceware.org/cygwinports/) :

     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.

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:

     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
