[PD] pick color of videostream?

[Yves Degoyon]

hola,

pdp_ctrack can work in silent mode,
( yuo don't need no xv for all your videos ),
the message to command the color picking are :

setcur 0.123 0.234 : sets the cursor on that position ( percentages 
expressed here )
pick : picks the color and outputs its RGB components


see help file,
saludos,
sevy
