Hell NGraziano.
I have found a possible bug with some nvr softwares (Hanwha specifically).
This nvr returns the port couple as 1-1, instead of 1-0 or 0-1.
I assume, reading from their documentation (sorry, I cannot provide shader it, is under N.D.A.), that some specific models returns coupe as 1-1, assuming it as 1-0.
This cause a bug in the data reading, as video is returned always as control, since is the first channel checked...
