The set frequency sometimes works correctly and I can see the images. Normally, the first set works and I can see the images; than i call the set frequency and (sometimes) the signal goes 0. In this moment to continue with other tests, I've put the set frequency ioctl in a do/while loop that continue to call the set frequency untill the signal goes >0 Of course, with other programs the card works Thank you !
