Mine is not dual core or more.. And that command(time with each command in
pipe) doesn't work. I don't how I am going to reduce the conversion
duration?!!!!
Another question, I'm using mjpegtools in ubuntu right now. When, I try to
install in debian. It is failing. Whether the package supports debian? I
need mjpegtools in debian machine.
