Hi When using double buffering, how do i get to know the number of missed frames. As of now if I do it by measuring the time lapsed between two consecutive CSYNC signals. If the time measure is more that 1/25th of a sec (assuming PAL capure) I think of it as a frame being lost. I am not sure if this is the right way to go about doing it. Please let me know if anyone has a better one. thanx in advance regards Vinod Kumar M.V.
