Executing ffmpeg from php exec function

Is there a way to execute the ffmpeg using php’s exec function?

Does anyone have a tutorial on how this works? according to dreamhost, the ffmpeg-php alternative they have in their wiki is out of date and will not work without a custom installation of php.

ffmpeg is available as dream host have installed across the board.

all you nned to do is exec(ffmepg …);

that shoudl do the trick

I attempted:

$cmd = ‘/usr/bin/ffmpeg -i /path/to/video/video.mpg -ab 90 -ar 22050 -b 500 -r 15 -s 640x480 /path/to/video/video.flv’;

and it creates the the .flv file, however, the .flv contains no data. It’s 0KB in size.
