faad2 compile
wget http://downloads.sourceforge.net/faac/faad2-2.7.tar.gz
./configure --prefix=/usr/alvastro/extras --enable-shared --enable-static
make ; mak install

faac-1.28 compile

speex를 컴파일 할때 libogg를 포함한다.
libogg
wget http://downloads.xiph.org/releases/ogg/libogg-1.1.3.tar.gz
./configure --prefix=/usr/alvastro/extras --enable-shared --enable-static
make;make install

speex
wget http://downloads.xiph.org/releases/speex/speex-1.2rc1.tar.gz
./configure --prefix=/usr/alvastro/extras --enable-shared --enable-static --with-ogg=/usr/alvastro/extras
make ;make install

libvorbis
wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.2.0.tar.gz
./configure --prefix=/usr/alvastro/extras --enable-shared --enable-static --with-ogg=/usr/alvastro/extras
make;make install

yasm for libx264
wget http://www.tortall.net/projects/yasm/releases/yasm-0.7.2.tar.gz
컴파일해도 안된다. ㅡㅡ;; asm은 패스 ;;
asm이 없으면 h.264로 엔코딩할때 시간이 많이 걸린다고 한다..

gpac for libx264
wget http://downloads.sourceforge.net/gpac/gpac-0.4.5.tar.gz
./configure --prefix=/usr/alvastro/extras --enable-shared --enable-static --disable-opengl
make clean;make
일단 opengl이 필요없으므로 컴파일하지 않는다..
cp -a bin/gcc/libgpac_static.a /usr/alvastro/extras/lib/
cp include -apR /usr/alvastro/extras/include

libx264
git clone git://git.videolan.org/x264.git
./configure --prefix=/usr/alvastro/extras --disable-asm --enable-shared --enable-mp4-output --extra-ldflags=-L/usr/alvastro/extras/lib --extra-cflags=-I/usr/alvastro/extras/include
make;make install

xvidcore
wget http://downloads.xvid.org/downloads/xvidcore-1.2.1.tar.gz
cd build/generic
./configure --prefix=/usr/alvastro/extras
make;make install

libmp3lame
wget http://downloads.sourceforge.net/project/lame/lame/3.98.4/lame-3.98.4.tar.gz
./configure --prefix=/usr/alvastro/extras --enable-shared --enable-static
make;make install

libtheora
wget http://downloads.xiph.org/releases/theora/libtheora-1.0.tar.bz2
