Tag: cross-platform solution

FFmpeg is a cross-platform solution for streaming audio and video as well as recording and conversion. There’s also a great PHP package called ffmpeg-php that allows for easy use of FFmpeg from inside PHP scripts. In this tutorial we will learn Install FFmpeg and FFmpeg-PHP Extension on CentOS server.

Install FFmpeg on CentOS

Step 1. To install, first you must add the DAG yum repository information corresponding to your CentOS/RHEL version to yum:

 #nano /etc/yum.repos.d/dag.repo

Add the following text to the file and save:

[dag]
name=DAG RPM Repository
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
enabled=1

Step 2. After add Dag repository, Use yum to install ffmpeg using following command.

#<code>rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
#yum install ffmpeg ffmpeg-devel ffmpeg-libpostproc

 Install FFmpeg-PHP Extension on CentOS

Step 1.

 #yum install php-gd php-devel

Step 2.Download the latest ffmpeg-php release

#wget http://nchc.dl.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
#make
#make install

If you get  [ffmpeg_movie.lo] Error 1 when compiling ffmpeg-php, then you will need to do:

#nano ffmpeg_movie.c
Changes in ffmpeg_movie.c:
#row 311: list_entry *le; to zend_rsrc_list_entry *le;
#row 346: list_entry new_le; to zend_rsrc_list_entry new_le;
#row 360: hashkey_length+1, (void *)&new_le, sizeof(list_entry), to hashkey_length+1, (void *)&new_le,sizeof(zend_rsrc_list_entry),

 

Step 3. Copy the ffmpeg.so module in php default module location. Now you have to edit php.ini file to enable ffmpeg-php support in it by using ffmpeg.so module.

 #nano /etc/php.ini

Put the below two lines at the end of the php.ini file

[ffmpeg]
extension=ffmpeg.so

FFmpeg-PHP extension should now be installed. You can check by creating a file called info.php in /var/www/html/ with the following content:

<?php phpinfo(); ?>
