I have a sync problem with my video experiment shield. I want to make a crosshair on my monitor. input signal signal is a digital cctv camera .
if I set “sync select” to “D9″ and set ” output select” to “SYNC ONLY” and in program if I make inactive initOverlay() comment everything is ok. there is no problem.
but if I set “sync select” to “V INPUT” and set ” output select ” to “OVERLAY” and in program if I make active initOverlay() comment. flickers and slidings are happening.
this is my code
