i build something like automatic VJ program . I have 2 incomig videos signals from 2 webcams and a couple of visualisations(at the moment 2 but i want more). I have a volume in dB of incoming audio signal and bpm of it as a nummbers. What I need is a routing/switchig of video output. For example: if am bpm number changes more then 20-30 bpm then changes a a visualisation or a webcam from first to second. And the same with volume.

I would be happy about a quick and dirty solution please.

Use a jit.xfade to fade between videos. Better yet the basic jit.gen object will do it as well. For the difference in numbers use the if object.

If the bpm is greater than 120 output a 1 (send to jit.xfade) else send 0.

If $1 > 120 then 1. else 0
If the bpm is greater than 120 output a 1 (send to jit.xfade) else send 0.
This should get you going.


my webcams are in umenu, not 2 qmetros. its not so simple. if i try "If $i1 >= $i1+20 || $i1

haw can i switch cams from umenu with the signal gain ? has someone a solution? and a visualisation switching works just in one direction. Has anyone a solution?
