The other day I was requested to set-up few requirements for a client such as mod_rewrite, GD library, PHP Dom, bcmath etc.. and among these in the list there was theFFMPEG library and the FFMPEG-PHP extension. OK, no big deal, but this box has CentOS 6 (RHEL6) with Virtualmin/Webmin set-up on top of it using the base repositories only, so let's do it I said...

ok, I took the following steps in order to install and set-up FFMPEG and FFMPEG-PHP in CentOS 6 with Virtualmin

1. Update the system
2. Install Development Tools
3. Protect base repositories
4. Add dag's repository
5. Install FFMPEG
6. Install FFMPEG-PHP
7. Load FFMPEG-PHP extension

yum update

yum groupinstall "Development tools"

Install the ProtectBase yum plugin by

yum install yum-protectbase

and then navigate to /etc/yum.repos.d

cd /etc/yum.repos.d/

before doing any changes to the repositories, always do backup of the original ones.

cp -prv ../yum.repos.d{,.orig}

in order for a repository to be protected, a line protect=1 needs to be added to each repository section in CentOS-Base.repo, CentOS-Media.repo and virtualmin.repo.

So, edit these files using your favourite editor or do the sed if you're feeling brave

sed -i '/gpgkey=/a\protect=1' CentOS-{Base,Media}.repo

sed -i '/gpgkey=/a\protect=1' virtualmin.repo

[dag]

name=Dag RPM Repository for Red Hat Enterprise Linux

baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag

gpgcheck=1

gpgkey=http://dag.wieers.com/packages/RPM-GPG-KEY.dag.txt

enabled=1

protect=0

next import dag's rpm gpg key by

wget http://dag.wieers.com/packages/RPM-GPG-KEY.dag.txt -P /tmp

rpm --import /tmp/RPM-GPG-KEY.dag.txt

yum install ffmpeg-devel php-devel re2c php-xml ffmpeg

verify FFMPEG is installed successfully by executing

ffmpeg

you should get something like

wget http://downloads.sourceforge.net/project/ffmpeg-php/ffmpeg-php/0.6.0/ffmpeg-php-0.6.0.tbz2

tar -xjf ffmpeg-php-0.6.0.tbz2

cd ffmpeg-php-0.6.0/

phpize

./configure

now run the following to prevent compilation failure with something like ffmpeg_frame.c:421: error: ‘PIX_FMT_RGBA32’ undeclared (first use in this function)

sed -i 's#PIX_FMT_RGBA32#PIX_FMT_RGB32#' ./ffmpeg_frame.c

and compile and install using

make

make install

you should end up with something like

Installing shared extensions:     /usr/lib64/php/modules/

echo -e "extension=ffmpeg.so\n" > /etc/php.d/ffmpeg.ini

restart the webserver by

/etc/init.d/httpd restart

verify that the FFMPEG-PHP extension is loaded

php -i | grep ffmpeg

php -m | grep ffmpeg
