ffmpeg-php installation and a few others.

[Botan]

I'm trying to setup on the fly flv conversion on my server, but have run into trouble.
I supposedly need ffmpeg, ffmpeg-php and mplayer (lame audio codec?)

I'm just guessing here, but this is what I have done so far: (note that i'm on a fedora server w/ cpanel)

yum install subversion
chmod 775 lib
chmod 775 bin
svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer
mv mplayer /usr/local/
mv ffmpeg /usr/local/
wget ftp://ftp6.mplayerhq.hu/MPlayer/releases/codecs/all-20060611.tar.bz2
bunzip2 all-20060611.tar.bz2
tar xvf all-20060611.tar
cd /usr/local/mplayer
mkdir codecs
cd ..
cd ..
cd ..
cd all-20060611
mv * /usr/local/mplayer/codecs
cd ..
rmdir all-20060611
cd /usr/local/mplayer
mv codecs /usr/local/lib
cd ..
cd ..
cd ..
mkdir mm
cd mm
wget http://rpm.livna.org/fedora/4/i386/lame-3.96.1-0.lvn.1.4.i386.rpm
sudo rpm -Uvh lame-3.96.1-0.lvn.1.4.i386.rpm
wget http://dag.wieers.com/packages/lame/lame-devel-3.96.1-4.fc1.rf.i386.rpm
sudo rpm -Uvh lame-devel-3.96.1-4.fc1.rf.i386.rpm
wget http://downloads.xvid.org/downloads/xvidcore-1.1.0.tar.bz2
bzip2 -cd xvidcore-1.1.0.tar.bz2 | tar xvf -
cd xvidcore-1.1.0/build/generic/
./configure
make
su -c 'make install'
cd ..
cd ..
cd ..
cd ..
su -c 'ln -s /usr/local/lib/codecs /usr/lib/win32'
cd /usr/local/mplayer
./configure --prefix=/usr --enable-largefiles --with-codecsdir=/usr/local/mplayer/codecs
make
su -c 'make install'
cd ..
cd ..
cd /usr/local/ffmpeg
./configure --prefix=/usr/local/ffmpeg --enable-mp3lame --extra-cflags=-I/usr/bin/lame/include

I dont know if i've done the above correctly, but assuming I have; I cant manage to install ffmpeg-php due to the fact that i'm supposed to find the php sources extensions directory.
Despite having root access on ssh; I have been unable to pinpoint it to continue.
Please give me some helpful guidance if you dont mind xD

I found the extensions directory. Simply go to php.ini and find where the extensions path is located. Note that only 1 copy/version of php can be installed to continue ffmpeg-php. This is the point where I must stop for now, as the server I'm working on has multiple.

It would be very great if someone could finish what I started, or run through how to do what I did and intended on doing, for other popular server operating systems.
