Hi Rob, Thank you for your help!
I tried your commend (the one at the bottom of this mail) and I still get the same screen: +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ |1=-10| |2= -5| |3= -2| |4= -1| |5= 0| |6= 1| |7= 2| |8= 5| |9= 10| +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +-----+ +---------------------------------------------------------------------+ | H = back 1 minute, L = forward 1 minute | | h = previous frame, l = next frame | | g = start of clip, j = next clip, k = previous clip | | 0 = restart, q = quit, space = play | +---------------------------------------------------------------------+ Current Position: 0 On this screen I have to be behind my computer and press "l" or "space" or whatever makes melt run... And that's the point: how can I launch the command line from a script (.sh or php) SERVER SIDE so that melt can work alone and treat the video. In other words, how can I make it work automatically? At the end, where can I found the testme.avi video to publish it for my students? Thank you so much ;-) Best Regards, Brice Vercoustre Le 22 mars 2010 à 14:12, Rob Canning a écrit : > Brice Vercoustre said : >> Hi all, >> >> I'm currently searching for a server side solution that would be able to >> handle picture-in-picture processing (insert a video thumbnail into another >> video). >> >> The purpose of that is to generate educational videos of university courses >> with a mix of both the teacher's screencast (main video) and it's face >> (thumbnail video). >> >> I'm looking for a command line app that would let me create such a video. >> The melt app really seems to do that, but I'm not sure I understood the >> mechanism well.
