This is a common error when we issue a “php -v” over command line or when we browse a phpinfo.php on a site.

To quickly fix this problem you will need to recompile your ffmpeg-php again.

How we fix this?


  1. #cd %ffmpeg-php-DIR%
  2. #vi ffmpeg-php.c

remove/comment the call to av_free_static()



rebuild ffmpeg-php and place the new on your extension directory.


Should be fixed.




HOW-TO FFMPEG under Linux.

On the last few months, we have seen a lot of customers trying to setup his own Video Sharing site (ex: youtube clone) with no luck, the implementation it’s not that hard to setup your linux server to allow video streaming. There are a lot of youtube sites around that may do this, what you only need is to setup your linux system to work with the requirements. Due this we have made this HOW TO FFMPEG post so customers and non-customers would do this by their end.


LAME MP3 Encoder


1) We download all the necessary packages.

  1. cd /usr/local/src
  2. wget
  3. wget
  4. wget
  5. wget
  6. wget
  7. wget
  8. svn checkout svn:// ffmpeg
  9. svn checkout svn:// mplayer

2) in order to install all the packages, we extract all of them.

  1. tar xzvf flvtool2_1.0.5_rc6.tgz
  2. tar xzvf lame-3.97.tar.gz
  3. tar xzvf libogg-1.1.3.tar.gz
  4. tar xzvf libvorbis-1.1.2.tar.gz
  5. tar xzvf flvtool2_1.0.5_rc6.tgz
  6. tar xjvf essential-20061022.tar.bz2
  7. tar xjvf ffmpeg-php-0.5.0.tbz2

3) We create a codecs directory so we can use it as default codec dir later. Then we copy the mplayer codecs to the new directory.

  1. mkdir /usr/local/lib/codecs/
  2. mv /usr/local/src/essential-20061022/* /usr/local/lib/codecs/
  3. chmod -R 755 /usr/local/lib/codecs/

4) We create a temporary TMP dir in order to safe compile everything.

  1. mkdir /usr/local/src/tmp
  2. chmod 777 /usr/local/src/tmp
  3. export TMPDIR=/usr/local/src/tmp

5) We start compiling & installing packages

a) For LAME:

  1. cd /usr/local/src/lame-3.97
  2. ./configure
  3. make
  4. make install

b) For LIBOGG:

  1. cd /usr/local/src/libogg-1.1.3
  2. ./configure
  3. make
  4. make install


  1. cd /usr/local/src/libvorbis-1.1.2
  2. ./configure
  3. make
  4. make install

d) For FLVTOOL2:

  1. cd /usr/local/src/flvtool2_1.0.5_rc6/
  2. ruby setup.rb config
  3. ruby setup.rb setup
  4. ruby setup.rb install

e) For MPlayer:

  1. cd /usr/local/src/mplayer
  2. ./configure
  3. make
  4. make install

f) For FFMPEG:

  1. cd /usr/local/src/ffmpeg/
  2. ./configure –enable-libmp3lame –enable-shared
  3. make
  4. make install

Some necessary linking,

  1. ln -s /usr/local/lib/ /usr/lib/
  2. ln -s /usr/local/lib/ /usr/lib/
  3. ln -s /usr/local/lib/ /usr/lib/
  4. ln -s /usr/local/lib/ /usr/lib/
  5. ln -s /usr/local/lib/ /usr/lib/


  1. cd /usr/local/src/ffmpeg-php-0.5.0/
  2. phpize
  3. ./configure
  4. make
  5. make install

Finally, we include the ffmpeg-php module to our php.ini

  1. echo ‘extension=/usr/local/lib/php/extensions/no-debug-non-zts-20020429/’ >> /usr/local/Zend/etc/php.ini

Restart apache:

  1. service httpd restart


Your installation is finish, now you need to check if the video streamin is working correctly on your website.

Keep in mind that most of the sites have different video rate conversion, this does not mean the installation is wrong, you will need to look on the PHP code of your video streaming site to see if its using ffmpeg and mencoder command line properly.
