Warning for popen

Can somebody please help me with this warning: 

Warning: popen() has been disabled for security reasons in /home/seemaj/public_html/kin/flash/modules/video/inc/functions.inc.php on line 203 error

I contacted my hosting company and their reply was:

Your software is trying to use a function on the server which we've disabled for security. I'm afraid you'll need to use different software or attempt to do bypass the use of this function in the software somehow.

Any suggestions please, Dolphin 6 worked fine!

hello this function work with ffmpeg. It's needed for video processing!

Sorry should have done a search first!! 

I see this topic has been discussed many times.

Thanks SashaE

You are welcome
