1. 우선 디렉토리를 생성한다. 아무 곳이나 해도 무방함. 
(주의할 것은 마운트 되는 곳에 하지 말 것: Permission denied 라는 메시지가 뜰 수 있음)
mkdir ~/ffmpeg
cd ~/ffmpeg

2.소스 가져오기..
wget http://www3.mplayerhq.hu/MPlayer/releases/codecs/ essential-20061022.tar.bz2
wget http://rubyforge.org/frs/download.php/9225/ flvtool2_1.0.5_rc6.tgz
wget http://easynews.dl.sourceforge.net/sourceforge/ lame/lame-3.97.tar.gz
wget http://superb-west.dl.sourceforge.net/sourceforge/ ffmpeg-php/ffmpeg-php-0.5.0.tbz2
wget http://downloads.xiph.org/releases/ ogg/libogg-1.1.3.tar.gz
wget http://downloads.xiph.org/releases/ vorbis/libvorbis-1.1.2.tar.gz 
 

3. 소스 압축풀기
bunzip2 essential-20061022.tar.bz2
tar xvf essential-20061022.tar
tar zxvf flvtool2_1.0.5_rc6.tgz
tar zxvf lame-3.97.tar.gz
bunzip2 ffmpeg-php-0.5.0.tbz2
tar xvf ffmpeg-php-0.5.0.tar
tar zxvf libogg-1.1.3.tar.gz

4. 코덱디렉토리 만들고 가져오기
mkdir /usr/local/lib/codecs/
mv /essential-20061022/* /usr/local/lib/codecs/
chmod -R 755 /usr/local/lib/codecs/
 

5. 최신버젼으로 가져오기위해.. SVN 설치...
