A lot of people are getting hiring people to install FFMPEG as they think it’s a difficult task, but it’s much easier than you think if you follow these instructions. You should have root access & basic Linux knowledge to the server to follow these instructions.

1. Create a directory to do our work in
mkdir ~/ffmpeg
cd ~/ffmpeg

2. Get all the source files
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. Extract all the source files
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
tar zxvf libvorbis-1.1.2.tar.gz

4. Create the codecs directory & import them
mkdir /usr/local/lib/codecs/
mv essential-20061022/* /usr/local/lib/codecs/
chmod -R 755 /usr/local/lib/codecs/

5. Install SVN/Ruby (Depends on OS, this is for RHEL/CentOS)
yum install subversion
yum install ruby
yum install ncurses-devel

6. Get the latest FFMPEG/MPlayer from the subversion
svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer

7. Compile LAME
cd ~/ffmpeg/lame-3.97
./configure
make
make install

8. Compile libOGG
cd ~/ffmpeg/libogg-1.1.3
./configure
make
make install

9. Compile libVorbis
cd ~/ffmpeg/libvorbis-1.1.2
./configure
make
make install

10. Compile flvtool2
cd ~/ffmpeg/flvtool2_1.0.5_rc6
ruby setup.rb config
ruby setup.rb setup
ruby setup.rb install

11. Compile MPlayer
cd ~/ffmpeg/mplayer
./configure
make
make install

12. Compile FFMPEG
cd ~/ffmpeg/ffmpeg
./configure --enable-libmp3lame --enable-libogg --enable-libvorbis --disable-mmx --enable-shared
echo '#define HAVE_LRINTF 1' >> config.h
make
make install

13. 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

14. Compile FFMPEG-PHP
cd ~/ffmpeg/ ffmpeg-php-0.5.0
phpize
./configure
make
make install

15. Install FFMPEG-PHP (make sure the php.ini path is correct.)
echo 'extension=/usr/local/lib/php/extensions/ no-debug-non-zts-20020429/ffmpeg.so' >> /usr/local/Zend/etc/php.ini

16. Restart Apache to load FFMPEG-PHP (Depends on OS, this is for RHEL/CentOS)
service httpd restart

17. Verify if it works
php -r 'phpinfo();' | grep ffmpeg

If you get a few lines such as
ffmpeg
ffmpeg support (ffmpeg-php) => enabled
ffmpeg-php version => 0.5.0
ffmpeg.allow_persistent => 0 => 0

Then everything is installed and working. FFMPEG, FFMPEG-PHP, MPlayer, MEncoder, flv2tool, LAME MP3 encoder & libOGG.

You’ve probably heard of ffmpeg-php and it’s wide usability mostly in sites that involve with videos such as YouTube or any other similar site. Here’s a bit of an introduction to it and how to use it.

First thing, you’ve got to check that your web hosting provider actually has ffmpeg & ffmpeg-php extension installed on your account and then you could get started with ffmpeg. You can check if it’s installed by creating a PHP script and executing the following code:

extension_loaded('ffmpeg') or die("ffmpeg extension not loaded");

If you get “ffmpeg extension not loaded” then your web hosting provider does not have ffmpeg installed, if you get nothing, then you’re one the good track!

ffmpeg-php is very simple to learn, what it is pretty much is an interface that works with the ffmpeg software to make it easier for PHP developers to access.

Like any object in PHP, you’ll have to start with creating a new instance of it. You can do that by using the following line:

$ffmpegInstance = new ffmpeg_movie(“/path/to/movie/”);

Now that you’ve had that, you can use that instance to use the many features of ffmpeg-php which are from knowing the duration of the movie/audio in seconds to retrieving the bitrate of the movie/audio file.

Once here, it’s pretty much like object oriented programming, ex:
$ffmpegInstance->getDuration(); // Gets the duration in secs.
$ffmpegInstance->getVideoCodec(); // What type of compression/codec used

This can be very helpful when coding anything that has to do with uploading videos because you can know a lot of information about it. I’ve made a small script that pretty much retrieves all the information that ffmpeg can get right here
