But, " xterm -e 'pkill mplayer ; mplayer -fs -zoom -tv device=/dev/video0 tv://' " command isn't working for me.

try:

xterm -e mplayer -fs -zoom -tv device=/dev/video0 tv://

do you have even /dev/video0 available with ls (list file) ?

Thanks for reply again, I checked /dev/ folder. In normally, there isn't "video0" in /dev/ folder; after pressing "FN+F6", yes there is "video0" in /dev" folder.

I run command which above, just open xterm with this message: "Can't execvp mplayer: No such file or directory."

I guess, FN key is a switch for on/off and hardware related.

Yes, so it is.

Hi everyone,

I found how works FN+F6 for me. This key is hardware related for switching on/off device. I tested it these steps:

1. I pressed FN+F6 and turned on webcam.
2. Restart computer.
3. Try open webcam and yes, webcam opened.

My goal was open webcam at the beginning and I made it.

Thanks too much to everyone!
