ffmpeg-php error

Hi

i get this error when i type the command php -r 'phpinfo();' | grep ffmpeg in ssh

PHP Warning: Unknown(): Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20020429/ffmpeg.so' - /usr/local/lib/php/extensions/no-debug-non-zts-20020429/ffmpeg.so: cannot open shared object file: No such file or directory in Unknown on line 0


what does this mean ??


Thanks


Harry

the error has changed to

Failed loading /usr/local/lib/php/extensions/ffmpeg.so: /usr/local/lib/php/extensions/ffmpeg.so: cannot dynamically load executable


do i need to chmod it ?
