This article describes how to install ffmpeg, mplayer, mencoder, flvtool2, ffmpeg-php with all supported codecs to convert/manipulate videos easily on CentOS 5.x. If you want to run sites like youtube, this article will help you to install the base for your software.
1. Setting-up RPMForge repository.
RPMForge repository (http://dag.wieers.com) is the biggest rpm repository for RHEL, and CentOS for all versions. Set up the RPMForge repository as mentioned here.
2. Install ffmpeg, mplayer, mencoder with all supported modules. Now we have rpmforge repository, so we will use yum to install ffmpeg, mplayer, mencoder as well as all dependent software.
yum -y install ffmpeg ffmpeg-devel mplayer mencoder flvtool2
This command will some time to download and install all packages depending on your internet speed.
3. Install FFMPEG-PHP
ffmpeg-php is an extension for PHP that adds an easy-to-use, object-oriented API for accessing and retrieving information from video and audio files. ffmpeg-devel and php-devel are needed to compile ffmpeg-php from the source code. Use the following steps to install ffmpeg-php
cd /usr/src wget http://garr.dl.sourceforge.net/sourceforge/ffmpeg-php/ffmpeg-php-x.x.x.tbz2 tar jxvf ffmpeg-php-x.x.x.tbz2 cd ffmpeg-php-x.x.x phpize ./configure make make install
It will 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.
vi /etc/php.ini
and append the following line
extension=ffmpeg.so
Restart Apache service to take effect of php.ini
/etc/init.d/httpd restart
If you are getting the following error while compiling the latest release of ffmpeg-php-0.6.0, follow the below steps.
Error
/usr/src/ffmpeg-php-0.6.0/ffmpeg_frame.c: In function âzim_ffmpeg_frame_toGDImageâ: /usr/src/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: âPIX_FMT_RGBA32â undeclared (first use in this function) /usr/src/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: (Each undeclared identifier is reported only once /usr/src/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: for each function it appears in.) /usr/src/ffmpeg-php-0.6.0/ffmpeg_frame.c: In function âzim_ffmpeg_frame_ffmpeg_frameâ: /usr/src/ffmpeg-php-0.6.0/ffmpeg_frame.c:421: error: âPIX_FMT_RGBA32â undeclared (first use in this function) make: *** [ffmpeg_frame.lo] Error 1
Solution
Under the ffmpeg-php-0.6.0 directory modify the file: ffmpeg_frame.c with nano or vi editors and replace every instance of PIX_FMT_RGBA32 with PIX_FMT_RGB32
1. vi ffmpeg_frame.c
2. Search for PIX_FMT_RGBA32 and replace it with PIX_FMT_RGB32
3. Exit from the editor
Then run the following commands:
cd /usr/local/src/ffmpeg-php-0.6.0 cp -aP ffmpeg_frame.loT ffmpeg_frame.lo make clean ./configure make make install
This should fix the errors given above. Finally, add the ffmpeg.so extension in php.ini and check phpinfo for the server you should see ffmpeg listed.
Run the following command to ffmpeg module listing in php.
php -m | grep ffmpeg
Enjoy streaming!!
