• FFMPEG on Fedora but PHP Compilation confliction

  11 octobre 2013, par UMI

  I have running Xampp with PHP5.5 on Fedora from Apache Friend, with default settings what the installer package do on Linux.

  When I install FFMPEG successfully and try to load from php.ini it always says:

  *

  11-Oct-2013 14:05:51 Europe/Berlin] PHP Warning:  PHP Startup: ffmpeg: Unable to initialize module
  Module compiled with module API=20060613
  PHP    compiled with module API=20121212
  These options need to match
  in Unknown on line 0
  

  *

  The only thing which is confusing me is that when I did phpize even that I already installed xampp server which means I have PHP running. FFMPEG phpize did not work and I had to install php-devel. Does that mean that FFMPEG is configured with PHP, other than the installed with XAMPP? I am not sure what is happening. Whatever I do I always receive this error message in php_error_log file.

  It is amazing :) that I just run below command to see what version of PHP is, I have and below are the results which are shocking one because I am in a feeling that I have PHP 5.5 installed and running from XAMMP.

  [root@localhost ~]# php -v
  PHP 5.2.6 (cli) (built: May  8 2008 08:53:44)
  Copyright (c) 1997-2008 The PHP Group
  Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies
  

  How can I get this covered that if I simple install XAMPP server on linux and want to install and configure FFMPEG along with?
