Daniel, This doesn't display anything: die($first); die($second); Full commands are: first: /usr/local/bin/mencoder -vf scale=448:-3,expand=448:336 -sws 9 -of lavf -ovc lavc -lavcopts vcodec=flv:vbitrate=250:trell:v4mv:mv0:mbd=2:cbp:aic:cmp=3:subcmp=3:vpass=1 -frames 800 -ofps 24000/1001 -oac mp3lame -lameopts abr:br=64:mode=0 -channels 1 -srate 22050 -of lavf -lavfopts format=flv -o /home/re/video/2/16.flv /home/re/ff/logo7.avi /home/re/video/2/16temp second: /usr/local/bin/mencoder -vf scale=448:-3,expand=448:336 -sws 9 -of lavf -ovc lavc -lavcopts vcodec=flv:vbitrate=250:trell:v4mv:mv0:mbd=2:cbp:aic:cmp=3:subcmp=3:vpass=1 -frames 800 -ofps 24000/1001 -oac mp3lame -lameopts abr:br=64:mode=0 -channels 1 -srate 22050 -of lavf -lavfopts format=flv -o /home/re/video/2/16.flv /home/re/ff/logo7.avi /home/re/video/2/16temp I've set permissions of all test files and directories to 777.

Yes. It's just describes codecs. But I know mencoder support those codecs, because it encodes videos when it's called from SSH. > Beyond that, it's a question that should probably instead be asked > on a mencoder mailing list, since PHP's system() function is working > correctly, but apparently isn't getting the information it needs to > pass stuff back-and-forth with the system. > I've already asked this question in Mencoder group, by noone replied. I thinkit's because mencoder works fine and it doesn't work only when I call it from PHP. The thing is when I copy/paste commands above to SSH, everything works fine. Do you have any thoughts?
