Installing FFMPEG.

yum install ffmpeg ffmpeg-devel

Install FFMPEG-PHP Extension

FFmpeg-php is a very good extension and wrapper for PHP which can pull useful information about video through API interface. Inorder to install it you will need to download the source file and then compile and install extension in your server.

cd /usr/local/src

wget http://downloads.sourceforge.net/project/ffmpeg-php/ffmpeg-php/0.6.0/ffmpeg-php-0.6.0.tbz2?use_mirror=nchc

tar -xjf ffmpeg-php-0.6.0.tbz2
cd ffmpeg-php-0.6.0.tbz2
phpize
./configure
make
make install

Once you have done that without any problems then you will see the php extension file /usr/local/lib/php/extensions/no-debug-non-zts-20060613/ffmpeg.so and you will need mention that extension in php.ini file.

nano /usr/local/lib/php.ini

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

[ffmpeg]
extension=ffmpeg.so

Then restart apache using — service httpd restart

If you get an error like this 
/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

Under the ffmpeg-php-0.6.0 directory modify the file: ffmpeg_frame.c with nano or vi editor and replace every instance of PIX_FMT_RGBA32 with PIX_FMT_RGB32

# nano ffmpeg_frame.c
# Search for PIX_FMT_RGBA32 and replace it with PIX_FMT_RGB32
# 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.
