-p <personal video path> %s\n\
Specify a personal folder containing a video \n\
to process.\n\
Example : \"/Temp/ViSP-images/video/video.mpeg\"\n\
\n\
-c\n\
Disable the mouse click. Useful to automaze the \n\
execution of this program without humain intervention.\n\

-d \n\
Turn off the display.\n\
