<p>Some parts of FFmpeg 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:

|
||
|
|
|
||
|
|
<p>If not, then you should install a different compiler that has no
|

hard-coded path to gas. In the worst case pass <code class="code">--disable-asm</code>

<p>If you compiled FFmpeg libraries statically and you want to use them to
|

build your own shared library, you may need to force PIC support (with
|
||
|
|
<code class="code">--enable-pic</code> during FFmpeg configure) and add the following option
|
||
|
|
to your project LDFLAGS:
|

<p>If your target platform requires position independent binaries, you should

pass the correct linking flag (e.g. <code class="code">-pie</code>) to <code class="code">--extra-ldexeflags</code>.

<p>GNU Make is required to build FFmpeg, so you have to invoke (<code class="command">gmake</code>),
|
||
|
|
standard Solaris Make will not work. When building with a non-c99 front-end
|

(gcc, generic suncc) add either <code class="code">--extra-libs=/usr/lib/values-xpg6.o</code>
|
||
|
|
or <code class="code">--extra-libs=/usr/lib/64/values-xpg6.o</code> 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:

<ul class="itemize mark-bullet">
|

|
|
<li>Building for the MSYS environment is discouraged, MSYS2 provides a full
|
||
|
|
MinGW-w64 environment through <samp class="file">mingw64_shell.bat</samp> or
|
||
|
|
<samp class="file">mingw32_shell.bat</samp> that should be used instead of the environment
|
||
|
|
provided by <samp class="file">msys2_shell.bat</samp>.
|
||
|
|
|
||
|
|
</li><li>Building using MSYS2 can be sped up by disabling implicit rules in the
|
||
|
|
Makefile by calling <code class="code">make -r</code> instead of plain <code class="code">make</code>. 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 during
|
||
|
|
<code class="code">make install</code>).
|
||
|
|
|
||
|
|
</li><li>In order to compile FFplay, you must have the MinGW development library
|
||
|
|
of <a class="uref" href="http://www.libsdl.org/">SDL</a> and <code class="code">pkg-config</code> installed.
|
||
|
|
|
||
|
|
</li><li>By using <code class="code">./configure --enable-shared</code> when configuring FFmpeg,
|
||
|
|
you can build the FFmpeg libraries (e.g. libavutil, libavcodec,
|
||
|
|
libavformat) as DLLs.

<p>FFmpeg can be built with MSVC 2013 or later.

|
|
</p>
|
||
|
|
<p>You will need the following prerequisites:
|
||
|
|
</p>
|
||
|
|
<ul class="itemize mark-bullet">
|
||
|
|
<li><a class="uref" href="http://msys2.github.io/">MSYS2</a>

</li><li><a class="uref" href="http://www.nasm.us/">NASM</a>
|
||
|
|
(Also available via MSYS2’s package manager.)
|
||
|
|
</li></ul>
|
||
|
|
|
||
|
|
<p>To set up a proper environment in MSYS2, you need to run <code class="code">msys_shell.bat</code> from
|
||
|
|
the Visual Studio or Intel Compiler command prompt.
|
||
|
|
</p>
|
||
|
|
<p>Place <code class="code">yasm.exe</code> somewhere in your <code class="code">PATH</code>.
|
||
|
|
</p>
|
||
|
|
<p>Next, make sure any other headers and libs you want to use, such as zlib, are
|
||
|
|
located in a spot that the compiler can see. Do so by modifying the <code class="code">LIB</code>
|
||
|
|
and <code class="code">INCLUDE</code> environment variables to include the <strong class="strong">Windows-style</strong>
|
||
|
|
paths to these directories. Alternatively, you can try to use the
|
||
|
|
<code class="code">--extra-cflags</code>/<code class="code">--extra-ldflags</code> configure options.
|
||
|
|
</p>
|
||
|
|
<p>Finally, run:
|
||
|
|
</p>
|
||
|
|
<div class="example">
|
||
|
|
<pre class="example-preformatted">For MSVC:
|
||
|
|
./configure --toolchain=msvc
|

For ICL:

||
|
|
|
||
|
|
<p>If you wish to compile shared libraries, add <code class="code">--enable-shared</code> to your
|
||
|
|
configure options. Note that due to the way MSVC and ICL handle DLL imports and
|
||
|
|
exports, you cannot compile static and shared libraries at the same time, and
|
||
|
|
enabling shared libraries will automatically disable the static ones.

<ul class="itemize mark-bullet">
|
||
|
|
<li>If you wish to build with zlib support, you will have to grab a compatible
|
||

zlib binary from somewhere, with an MSVC import lib, or if you wish to link
|
||
|
|
statically, you can follow the instructions below to build a compatible
|
||
|
|
<code class="code">zlib.lib</code> with MSVC. Regardless of which method you use, you must still
|
||
|
|
follow step 3, or compilation will fail.

<h4 class="subsection">4.2.1 Linking to FFmpeg with Microsoft Visual C++</h4>
|
||
|
|
|
||
|
|
<p>If you plan to link with MSVC-built static libraries, you will need
|
||
|
|
to make sure you have <code class="code">Runtime Library</code> set to
|
||
|
|
<code class="code">Multi-threaded (/MT)</code> in your project’s settings.
|
||
|
|
</p>
|
||
|
|
<p>You will need to define <code class="code">inline</code> to something MSVC understands:
|
||
|
|
</p><div class="example">
|
||
|
|
<pre class="example-preformatted">#define inline __inline
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p>Also note, that as stated in <strong class="strong">Microsoft Visual C++</strong>, you will need
|
||
|
|
an MSVC-compatible <a class="uref" href="http://code.google.com/p/msinttypes/">inttypes.h</a>.
|
||
|
|
</p>
|
||
|
|
<p>If you plan on using import libraries created by dlltool, you must
|
||
|
|
set <code class="code">References</code> to <code class="code">No (/OPT:NOREF)</code> under the linker optimization
|
||
|
|
settings, otherwise the resulting binaries will fail during runtime.
|
||
|
|
This is not required when using import libraries generated by <code class="code">lib.exe</code>.
|
||
|
|
This issue is reported upstream at
|
||
|
|
<a class="url" href="http://sourceware.org/bugzilla/show_bug.cgi?id=12633">http://sourceware.org/bugzilla/show_bug.cgi?id=12633</a>.
|
||
|
|
</p>
|
||
|
|
<p>To create import libraries that work with the <code class="code">/OPT:REF</code> option
|
||
|
|
(which is enabled by default in Release mode), follow these steps:
|
||
|
|
</p>
|
||
|
|
<ol class="enumerate">
|
||
|
|
<li> Open the <em class="emph">Visual Studio Command Prompt</em>.
|
||
|
|
|
||
|
|
<p>Alternatively, in a normal command line prompt, call <samp class="file">vcvars32.bat</samp>
|
||
|
|
which sets up the environment variables for the Visual C++ tools
|
||
|
|
(the standard location for this file is something like
|
||
|
|
<samp class="file">C:\Program Files (x86_\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat</samp>).
|
||
|
|
</p>
|
||
|
|
</li><li> Enter the <samp class="file">bin</samp> directory where the created LIB and DLL files
|
||
|
|
are stored.
|
||
|
|
|
||
|
|
</li><li> Generate new import libraries with <code class="command">lib.exe</code>:
|
||
|
|
|
||
|
|
<div class="example">
|
||
|
|
<pre class="example-preformatted">lib /machine:i386 /def:..\lib\foo-version.def /out:foo.lib
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p>Replace <code class="code">foo-version</code> and <code class="code">foo</code> with the respective library names.

<h3 class="section">4.3 Cross compilation for Windows with Linux</h3>
|

|
|
|

|
|
<p>You must use the MinGW cross compilation tools available at
|
||
|
|
<a class="url" href="http://www.mingw.org/">http://www.mingw.org/</a>.
|
||
|
|
</p>
|
||
|
|
<p>Then configure FFmpeg with the following options:
|
||
|
|
</p><div class="example">
|
||
|
|
<pre class="example-preformatted">./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
|
||
|
|
</pre></div>
|
||
|
|
<p>(you can change the cross-prefix according to the prefix chosen for the
|
||
|
|
MinGW tools).
|
||
|
|
</p>
|
||
|
|
<p>Then you can easily test FFmpeg with <a class="uref" href="http://www.winehq.com/">Wine</a>.

|
||
|
|
<h3 class="section">4.4 Compilation under Cygwin</h3>
|
||
|
|
|
||
|
|
<p>Please use Cygwin 1.7.x as the obsolete 1.5.x Cygwin versions lack
|
||
|
|
llrint() in its C library.
|
||
|
|
</p>
|
||
|
|
<p>Install your Cygwin with all the "Base" packages, plus the
|
||
|
|
following "Devel" ones:
|
||
|
|
</p><div class="example">
|
||
|
|
<pre class="example-preformatted">binutils, gcc4-core, make, git, mingw-runtime, texinfo
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p>In order to run FATE you will also need the following "Utils" packages:
|
||
|
|
</p><div class="example">
|
||
|
|
<pre class="example-preformatted">diffutils
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p>If you want to build FFmpeg with additional libraries, download Cygwin
|
||
|
|
"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
|
||
|
|
</p><div class="example">
|
||
|
|
<pre class="example-preformatted">libogg-devel, libvorbis-devel
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p>These library packages are only available from
|
||
|
|
<a class="uref" href="http://sourceware.org/cygwinports/">Cygwin Ports</a>:
|
||
|
|
</p>
|
||
|
|
<div class="example">
|
||
|
|
<pre class="example-preformatted">yasm, libSDL-devel, libgsm-devel, libmp3lame-devel,
|
||
|
|
speex-devel, libtheora-devel, libxvidcore-devel
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p>The recommendation for x264 is to build it from source, as it evolves too
|
||
|
|
quickly for Cygwin Ports to be up to date.

<p>With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
|

|
|
</p>
|
||
|
|
<p>Just install your Cygwin as explained before, plus these additional

|
|
|

|
|
<p>and add some special flags to your configure invocation.
|

<p>For a static build run
|
