If FFmpeg is not shipped, we may have to build it from source. The FFmpeg wiki has a really good compilation guide[1] and it's a good advice to follow it, since there are quite a few dependencies to build first. Here's the short version for some distributions.

Note: we will install each dependency in its own directory!


yum install autoconf automake gcc gcc-c++ git libtool make nasm pkgconfig zlib-devel   # Fedora
apt-get install autoconf automake gcc g++ git libtool make nasm pkg-config zlib1g-dev  # Debian, Ubuntu

Instead of running "make install" as root every time, we temporarily allow ourselves to write to our installation directory:

sudo setfacl -m u:$USER:rwx /opt


git clone git://github.com/yasm/yasm.git yasm-git
cd yasm-git

./configure --prefix=/opt/x264 --enable-static && make && make install
sudo ln -s /opt/yasm/bin/yasm /usr/local/bin/yasm


git clone --depth 1 git://git.videolan.org/x264 x264-git
cd x264-git

./configure --prefix=/opt/x264 --enable-static && make && make install


git clone --depth 1 git://git.code.sf.net/p/opencore-amr/fdk-aac fdk-aac-git
cd fdk-aac-git

autoreconf -fiv && ./configure --prefix=/opt/libfdk-aac --disable-shared && make && make install


cvs -d:pserver:anonymous@lame.cvs.sourceforge.net:/cvsroot/lame login
cvs -z3 -d:pserver:anonymous@lame.cvs.sourceforge.net:/cvsroot/lame co -P lame
mv lame lame-cvs && cd lame-cvs

./configure --prefix=/opt/lame --disable-shared --enable-nasm && make && make install


git clone git://git.xiph.org/opus.git opus-git
cd opus-git

./autogen.sh && ./configure --prefix=/opt/libopus --disable-shared && make && make install


git clone git://git.xiph.org/mirrors/ogg.git libogg-git
cd libogg-git

./autogen.sh && ./configure --prefix=/opt/libogg --disable-shared && make && make install


git clone git://git.xiph.org/mirrors/vorbis.git vorbis-git
cd vorbis-git

PKG_CONFIG_PATH=/opt/libogg/lib/pkgconfig ./autogen.sh --prefix=/opt/libvorbis --with-ogg=/opt/libogg --disable-shared && make && make install


git clone git://git.xiph.org/mirrors/theora.git theora-git
cd theora-git

PKG_CONFIG_PATH=/opt/libogg/lib/pkgconfig ./autogen.sh --prefix=/opt/libtheora --with-ogg=/opt/libogg --disable-examples --disable-shared --disable-sdltest --disable-vorbistest && make && make install


git clone --depth 1 http://git.chromium.org/webm/libvpx.git libvpx-git
cd libvpx-git

./configure --prefix=/opt/libvpx --disable-examples && make && make install


Xvid does indeed provide access to their SVN server[2]:

svn co --username anonymous --password "" http://svn.xvid.org/trunk/xvidcore xvidcore-svn
cd xvidcore-svn/build/generic

If this is not working, get their latest snapshot:

wget http://downloads.xvid.org/downloads/xvid_latest.tar.gz
tar -xjf xvid_latest.tar.gz
cd xvid_*/trunk/xvidcore/build/generic

./configure --prefix=/opt/xvidcore && make && make install


Now we can build FFmpeg:

git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg-git
cd ffmpeg-git

Since we installed every dependecy in its own directory we have to create our build flags first:

export INCDIR="-I`echo /opt/{x264,lame,libfdk-aac,libfdk-aac,libopus,libogg,libvorbis,libvpx,libtheora,xvidcore}/include | sed 's/ / -I/g'`"

export LIBDIR="-L`echo /opt/{x264,lame,libfdk-aac,libfdk-aac,libopus,libogg,libvorbis,libvpx,libtheora,xvidcore}/lib | sed 's/ / -L/g'`"

Of course, it would be easier to just install the distributions packages:

sudo apt-get install yasm libfdk-aac-dev libmp3lame-dev libopus-dev libtheora-dev libvorbis-dev libvpx-dev libx264-dev libxvidcore-de
sudo     yum install yasm libtheora-devel libvpx-devel opus-devel 

As our TMPDIR was mounted noexec, we have to use another directory:

mkdir tmp
TMPDIR=$PWD/tmp ./configure --prefix=/opt/ffmpeg --extra-cflags="$INCDIR" --extra-ldflags="$LIBDIR" --extra-libs="-ldl" --enable-gpl --enable-nonfree --enable-libvpx --enable-libx264 --enable-libfdk_aac --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libtheora --enable-libxvid
make && make install

Correct the permissions again:

sudo setfacl -x u:$USER /opt
sudo chown -R root:root /opt/{yasm,x264,libfdk-aac,lame,libopus,libogg,libvorbis,libvpx,libtheora,ffmpeg}


With macports:

port install yasm
port install x264 +asm configure.compiler=llvm-gcc-4.2
port install ffmpeg
