Correct! To verify whether ffmpeg-php can utilize your ffmpeg binary or not use the following commands from your ssh: which ffmpeg Code (markup): This should return the path to some /usr/bin or /usr/local/bin if its installed. To verify the status of ffmpeg-php under ffmpeg module use this command: php -r 'phpinfo();' | grep ffmpeg Code (markup): This should return a 3 lines path including ffmpeg binaries and stuffs. Sometimes for lib problem, you will see more than 3 lines explaining some other paths. If thus, then just type ffmpeg in your shell prompt and if it returns any error, try to fix it by contacting your host or admin. Otherwise it should return you the ffmpeg manual. Good Luck
ffmpeg is never setup as default, first install ffmpeg and then install the ffmpeg-php extension. If you have not done this before then you should consider hiring an server admin to do it for you.
