yum install ruby (If you’re on cPanel you can alternatively use /scripts/installruby)
yum install ncurses-devel

Get FFMPEG and MPlayer from SVN:

svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer

Install LAME:

cd /usr/src/lame-3.97
./configure && make && make install

Install libOgg and libVorbis:

yum install libogg.i386 libvorbis.i386 libvorbis-devel.i386

Install flvtool2:

cd /usr/src/flvtool2-1.0.6/
ruby setup.rb config
ruby setup.rb setup
ruby setup.rb install

Install MPlayer:

cd /usr/src/MPlayer-1.0rc2
./configure && make && make install

Install ffMPEG:

cd /usr/src/ffmpeg/
mkdir tmp
chmod 777 tmp
export TMPDIR=./tmp
./configure –enable-libmp3lame –enable-libvorbis –disable-mmx –enable-shared
echo ‘#define HAVE_LRINTF 1? >> config.h
make && make install
export TMPDIR=/tmp

Finalize the codec setups:
ln -s /usr/local/lib/libavformat.so.50 /usr/lib/libavformat.so.50
ln -s /usr/local/lib/libavcodec.so.51 /usr/lib/libavcodec.so.51
ln -s /usr/local/lib/libavutil.so.49 /usr/lib/libavutil.so.49
ln -s /usr/local/lib/libmp3lame.so.0 /usr/lib/libmp3lame.so.0
ln -s /usr/local/lib/libavformat.so.51 /usr/lib/libavformat.so.51

You may get an error about a library path not being found, if so, run:
export LD_LIBRARY_PATH=/usr/local/lib

Install FFMPEG-PHP:

cd /usr/src/ffmpeg-php-0.5.0/
phpize
./configure && make && make install
ln -s /usr/local/bin/ffmpeg /usr/bin/ffmpeg
ln -s /usr/local/bin/mplayer /usr/bin/mplayer

Add extension to php.ini (find the correct php.ini file):
[ffmpeg]
extension_dir=/usr/local/lib/php/extensions/no-debug-non-zts-20060613/ffmpeg.so
extension=ffmpeg.so

Restart Apache and check that the module is loaded in PHP:

/etc/init.d/httpd restart

Test ffmpeg from command line and if you get this errors:

ffmpeg: error while loading shared libraries: libavformat.so.51:…

execute: /usr/local/lib >>/etc/ld.so.conf and reload library cache with ldconfig -v

Verify ffmpeg installation:

php -r ‘phpinfo();’ | grep ffmpeg

If you get the folowing results then FFMPEG and all it’s components are installed correctly:
ffmpeg
ffmpeg support (ffmpeg-php) => enabled
ffmpeg-php version => 0.5.3.1
