QUESTION · EXTRA HOURS

I've been trying to use Python to connect a pan-tilt zoom camera with RTSP and control it through Visca, but I failed. Should I get a different approach?

THE PANEL'S ANSWER
Carl

A Constellation hardware control box can handle VISCA over IP/ethernet natively; even a 1ME Constellation HD can serve as a VISCA control interface. You can vibe-code it easily using the API documentation in Blackmagic manuals. For RS-422 control, you need intermediate hardware; for VISCA over IP, Constellation is a good option.

VISCA can be encapsulated over ethernet using TCP or UDP. Approach depends on camera brand and interface type (RS-232, RS-422, ethernet). Some older Sony cameras used mini-plug RS-232 connections; modern cameras often support IP-based VISCA for zoom and focus control.

Use Claude or ChatGPT with explicit details: camera model (VISCA comes in TCP/UDP variants), network address, and credentials. Run Claude CLI on a dedicated Linux box on the same subnet to communicate with the camera without opening the GUI. Build reusable agents (e.g., named 'newcastle', 'sarah') to chain tasks and control multiple cameras.

50:29Talking about vibe coding and controlling gear, I've been trying to use Python to connect a pan-tilt zoom camera with RTSP and control it through Vizca, which is a control interface for cameras, but I failed. Should I get a different approach? Guy. Yeah, I'm curious as to what model of camera it is, because there is different flavors of Vizca. There's like TCP and UDP.

50:57And so I'm curious if there's a way to do it with ChatGPT or Clod or one of the bigger frontier models. I'm curious as to which one you're working with, because they're pretty dang smart, should be able to figure it out. But what might be helpful is if you have it plugged in via the camera plugged in on the same subnet, same network, and you're able to access it via GUI, then be more specific and tell Claude or use the actual app.

51:24Use the download the app and put it on your machine. Like I have a Linux box that just is Claude CLI, and I could point it at something as long as it's on the same subnet and have it talking to it pretty quick. But I'm explicit. listen, I say, Hey, it's on the network at this address. And here's the credentials here. It's

51:42admin and admin, if that's the default. And it can go in there. Like I've had mine do crazy stuff. I was telling it to SRT out to a specific address in Azure at a certain bit rate, just because I was being lazy. I was just like, yeah, you go do it for me. I don't even want to open up the GUI. And it was just like, sure. It took a while and I was watching it and it figures it out. It was

52:03is actually going in there it's just burning tokens i mean sometimes i don't know why i do some of the stuff i do but this is where the subsidized uh like in the future we may not be able to be this crazy uh because you know the there's a true cost of these tokens and uh they're being heavily subsidized by these frontier models so sometimes you get too many things bacon and

52:24you're just like oh yeah you could do that for me and you could do that for me this is a cool thing about grokbots too is uh you can just keep spinning them up and you can just say uh one of mine's called newcastle you could be like newcastle you go do this and uh sarah you you watch him do that when he's done go assign him this and that and you get a loop going it's pretty cool mickey

52:46writing in from the chat where's one f jeff to say central control yeah go ahead so yeah you can put a hardware box that controls via visca and then as long as that hardware box can understand commands can be some api all constellations so just a baby constellation so one of me constellation could do this now so and of course blackmagic has apis and sdks but apis to control the constellation

53:13and because you can plug in via ethernet so in other words all constellations can control will have what's called visca via ethernet via ip so that's one way so if you have a constellation even just a 1me constellation hd you can now use that as a visca control box um and you can essentially even vibe code that easily because you know you have a documentation in the back

53:34of the manual as we said before for the black magic products that have apis um so yeah so any constellation can do uh visca via ip if that's what you're trying to do if you're trying to do it via rs422 that's a different thing altogether so therefore you'll need a box which technically the constellations have that as well but i won't come to that um but yeah so there are other ways

53:54of doing it but you will need a box in the middle that will do it the constellation is a good example of that courtney yeah it depends on what ptz you're using and what what whether it has an rs232 interface or if you're just communicating over ethernet and you could use biscuit as was mentioned encapsulated over ethernet over uh udm uh udp or tcp uh so it depends depends on what

54:19brand camera etc was as was mentioned but yeah i i go back to when sony cameras had that little mini plug with this guy plugged in and set it over uh rs232 feed uh to the camera to control So zoom and focus on all the other good stuff.
