Ok - I have installed everything referenced on this page:
http://wiki.freepbx.org/display/FOP/Installing+Media+Conversion+Libraries
and I still don’t have it working - do you need php-ffmpeg?
Could someone post a list of the actual dependencies so we are not just guessing - Everything is working except iPhones - they throw a message saying I haven’t installed the necessary libraries - Can we get a list of what we are actually looking for?
