The [pretty much] Complete Guide to Installing ffMPEG and Audio Binaries

Posted by Nessa | Posted in uncategorized | Posted on 07-01-2008


I know you’ve provably seen a lot of guides on how to install ffMPEG, but I’ve noticed that most of them are incomplete and don’t cover the possible issues that can arise during installation. I’ve installed ffMPEG on dozens of servers and have devised a standardized procedure on what I feel is the best way to perform this installation.

This walkthrough has been tested on systems running Redhat 9, RHEL 4, and CentOS 4.5 and it may also work on other distributions and versions. Our servers also run cPanel 11, but this is in no way required in order to install ffMPEG. I assume at this point that you have root access and that yum (or another similar package manager) is installed.

ffMPEG commonly consists of and includes the following software:

– Essential / MPlayer
– FLVtool2 (Requires a Ruby Core)
– LAME MP3 Encoder
– php-ffMPEG
– ffMPEG
– libOgg
– libvorbis

To start out, enter into a temporary source directory and download all the binaries:

cd /usr/src

*These are the latest stable versions at the time this article was written. If you are unable to download any of the above, you’ll need to visit the distributor’s site and download the latest stable version available.

Now extract everything:

bunzip2 essential-20061022.tar.bz2; tar xvf essential-20061022.tar
tar zxvf flvtool2-1.0.6.tgz
tar zxvf lame-3.97.tar.gz
bunzip2 ffmpeg-php-0.5.0.tbz2; tar xvf ffmpeg-php-0.5.0.tar
bunzip2 MPlayer-1.0rc2.tar.bz2 ; tar -xvf MPlayer-1.0rc2.tar

Create and import the Codecs directory:

mkdir /usr/local/lib/codecs/
mv essential-20061022/* /usr/local/lib/codecs/
chmod -Rf 755 /usr/local/lib/codecs/

Install Subversion and Ruby

yum install subversion
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:// ffmpeg
svn checkout svn:// mplayer

Install LAME:

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

Install libOgg and libVorbis:

yum install libogg.i386
yum install libvorbis.i386
yum install 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

HTML Email Template Pack - PC Version

Install ffMPEG:

cd /usr/src/ffmpeg/
./configure --enable-libmp3lame --enable-libvorbis --disable-mmx --enable-shared
make && make install

This is the typical configure line that I use, but you can customize this to what you need. For available configure options, type ./configure –help. Your custom configuration may require the installation of additional software on the server.

ln -s /usr/local/lib/ /usr/lib/
ln -s /usr/local/lib/ /usr/lib/
ln -s /usr/local/lib/ /usr/lib/
ln -s /usr/local/lib/ /usr/lib/
ln -s /usr/local/lib/ /usr/lib/

You may get an error about a library path not being found, if so, run

export LD_LIBRARY_PATH=/usr/local/lib

If this is being installed on a dedicated server, you might also get an error about the /tmp directory not be executable, which is common when installing on a dedicated server with a separate /tmp partition mounted noexec. In this case, you will need to create a tmp dir in the ffmpeg folder and use that as the tmp disk for now:

mkdir tmp
chmod 777 tmp
export TMPDIR=./tmp

Then run the configure command and set the TMPDIR variable back.

export TMPDIR=/tmp

Install ffMPEG-php

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

When the installation is complete, it will give you a long path to the shared libraries. This needs to be copied to the php.ini as so:


or in most cases where the extension_dir variable is set, just do:


The ‘no-debug-non-zts-xxxxxxxx’ directory will be the one provided during installation. When this is done, restart Apache and check that the module is loaded in PHP:

/etc/init.d/httpd restart
php -r 'phpinfo();' | grep ffmpeg

Look for this:

fmpeg support (ffmpeg-php) => enabled
ffmpeg-php version => 0.5.0
ffmpeg.allow_persistent => 0 => 0

If you only get output for the ‘PWD’ variables, make sure that the extension_dir path is correct in the phpinfo file. Sometimes there are two specified, and if that is the case then the incorrect one should be commented out.

Test out ffmpeg for errors just by typing ffmpeg at the command line. The most common error is:

ffmpeg: error while loading shared libraries: cannot open...

To correct this, edit /etc/ and add the line


then save and exit.

Now run this command to reload the library cache:

ldconfig -v

You’re all done…enjoy!

Upgrade to Subversion 1.4.x on CentOS

Posted by Nessa | Posted in uncategorized | Posted on 04-12-2007


I don’t know if it’s just me, but it seems that CentOS is kinda slow with their software updates. It’s not too big of a deal since CentOS is based off of RHEL so you can usually use RHEL 4-5 RPM’s, but those usually bombard me with failed dependencies. I find that the generic x86 RPMs do the trick, so for any of you trying to update your Subversion installations to a more recent version, here’s what you have to do on CentOS:

Optionally remove the old version by running yum remove subversion (assuming you installed with Yum)



rpm -i apr-util-1.2.8-1.i386.rpm
rpm -i apr-1.2.8-1.i386.rpm
rpm -i subversion-1.4.5-1.i386.rpm

Some people may have to do a ‘yum install postgresql-libs’ as for some reason APR wants that stuff.

Yum GCC Errors

Posted by Nessa | Posted in Uncategorized | Posted on 17-11-2007


This is coming from Shelby as a fix for the CentOS gcc compiler error that occurs when you try run a Yum update on some systems:

--> Processing Dependency: glibc-common = 2.3.4-2.25 for package: glibc-dummy-centos-4
--> Finished Dependency Resolution
Error: Missing Dependency: glibc-common = 2.3.4-2.25 is needed by package glibc-dummy-centos-4

First you have to remove the existing package:

yum remove glibc-dummy-centos-4

Then you have to reinstall gcc:

yum install gcc & yum install gcc*

Then you should be able to proceed running the yum update command.
