I've got the script working for a bit. My server fullfill the requirements, my phpinfo.php displays the right things for ffmpeg, but I still keep struggeling with the problem the video's are not being converted to flv. I'm using 2.4 right now. In this version I can't find a debug mode, how can I see what's going on when the converting starts..?

Edit: Besides that, I have a thumbnail problem. I uploaded a .3gp video, the thumbnail shows up (not converted to the flvideo map!) but when I upload a .mp4 video, the thumbnail won't be created.
