that was the easiest way for me to make it work. but thanks for the ideas.
i'd probably use all shell if i had to process too many videos,
needing to use all the cores in the LTSP lab, w/c don't have php
easily.
or if the cores are all in the web and we can't run shell easily then
all php maybe...
added some if (file_exists($finalfile)) { die...} after the
array_pop... so it can be used in batch files and run as many times in
parallel as you want the cores to be busy.
