Hey guys. Here's the thing, i'v decided to experiment a bit, and create a mini version of you tube, just for the sake of it, to understand how it works. Now, the basic idea, is for the script to convert video files into FLV files, and stream them. As far as i understood, the way to do that, is using FFMPEG and a command, which should be ran through CMD - ffmpeg -i file.avi file.flv The question is - how do i get PHP script to execute it for me? As far as i understood, it's done with one of several functions - exec or system. Can anybody help me out please? I'v tried running the following script: [code]<?php $cmd = "ipconfig"; system($cmd,$return_value); ($return_value == 0) or die("returned an error: $cmd"); ?> [/code] But for some reason, it just wont run, causing the browser to stop at some point, while loading
