On a 64bit CentOS 5.3 with PHP 5.2.11, the extension compiled and installed fine however Apache will not load it and spit out the error below:

PHP Warning:  PHP Startup: Unable to load dynamic library ‘/usr/lib64/php/modules/ffmpeg.so’ – /usr/lib64/php/modules/ffmpeg.so: undefined symbol: php_gd_gdImageSetPixel in Unknown on line 0

Surely enough, the GD extension was there, but why is ffmpeg complaining about not finding that shared symbol? Because, ffmpeg is loading first than GD (alphabetically) and such symbol has not been loaded. After adding the GD extension line on top of ffmpeg making sure it loads first the error went away and all is well again.
