The line obs.signal_handler_connect(sh,"show",showing) sets a signal handler for the refresh source that gets called when that source is "Showing" anywhere in OBS (preview or program).DCStrato - Thanks v.much for your rapid reply. i'll give this new script an outing!
You mention above some new code for auto camera control; is that the same/development as mentioned above (Sept 13 2020)? Is the code available as per Sept 15 2020 above? Does it integrate with OBS Studio?
I find the PTZ Optics Controller not that user friendly (and the User Manual out of date and useless!)
So I would be very interested in trying out something different (using Visca over IP?)
What do you mean by " doing "show" tests with callbacks " ?!!
(Sorry, I'm in UK and so 7 hours ahead of you in Colorado)
