If you know anything about pinewood derby races...
I've got a laptop that is connected to a video projector. I have an adapter that converts the laptop's HDMI signal to the projector's VGA signal. The laptop is collecting data from the race track and displaying it on the laptop's monitor, which is then mirrored on the video projector. All that works fine.
What I also want to do is put a video camera (e.g., GoPro) in place to show the cars as they come across the finish line. How can I get the output of the video camera to the laptop (so that it can also be shown on the video projector)?
Thanks.

OBS (Open Broadcaster Software) would likely fit nicely. It's aimed at streaming, but it supports (multiple)camera overlays over a main screen. I've used it and it worked well.

Didn't know about the pinewood derby races.
kinda cool.
Don't know about the technical stuff you're asking; sorry.
I'd rather be phishing!

In other words, your response is just as helpful as mine.

They don't have scouting where you are?

yes, but they thought I was not cool enough to join. (somewhere in the early 80s)

When I was a boy, scouting for girls was cool.
Scouting for boys was for the forest nerds.

Scouts were too much religious at that time and refuses all anti-christs non baptized kids.

I suppose via cable is not an option ?

The laptop's HDMI port is connected to the video projector, and the two USB ports are being used (one is connected to the race track, and the other is connected to the mouse/keyboard).

Have you tried connecting a USB hub to give you more connections?
Also, many cameras have a network port so you could just create a small network containing the camera and the laptop.
I connected to 68 cameras to a server this way. I then wrote software to enable multiple streams from any of them - they had been restricted to only two per camera but this method enabled more than that.
- I would love to change the world, but they won’t give me the source code.

USB Hub and USB cable to your GoPro is probably the best solution.

Just curios. For you ASP.net developers out there. If you were to start a new project, which would you use and why?

To answer your questions, "it depends", and "because". 
Microsoft are pushing .NET Core as the future, and won't be making any further changes to the .NET Framework. It's not going away any time soon, but the features and performance will never improve, and any bugs which don't impact security will never be fixed.
You can get some C# 8 features to work in a .NET Framework project by manually editing the project file; others require additional NuGet packages; and some won't work at all. I think some of the new features are terrible - particularly the tangled mess that came out of "default interface methods" - but without upgrading to .NET Core, you probably won't be able to take advantage of any further improvements to the language.
But at the same time, we regularly need to display or export SSRS reports from our applications. I have yet to find a reliable way of doing that which would work in .NET Core.
We also occasionally have to interact with a third-party ERP system which uses a WCF interface with a custom closed-source message format. I have yet to see whether it's possible to make that work in Core.
I don't think we've yet reached the point where newer libraries are dropping support for .NET Framework. Microsoft tried it with EF Core 3.0, but changed their minds for 3.1, which caused a complete mess. Having said that, it's probably only a matter of time, especially with ".NET 5" allegedly slated for release later this year.

Sounds like it would be OK to use .Net Core for newbasic web apps. But anything legacy would probably require .Net Framework.

I totaloly agree here. What a terrible idea.
Thanks for your input

Yeah, why is 3.1 a long term support version if they are going to .Net 5 right away?
I haven't seen a new C# feature in a while that was much of an improvement and most of them obscure the readability of the code.
I find it funny that they are pushing WPF with no compelling reason. I tested and a WinForm app calls .Net Core 3.1 assemblies just fine.

Because they need a version for customers who're unable/unwilling to upgrade framework versions every few month (3.1 LTS) while they work on the next version for early adoptersunpaid beta testers (5.0).
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

We have a butt-load of WCF services. We won't be switching over anytime soon.

Given where you work, I'm amazed you've managed to drag them up as far as MVC.

Caveat - we *still* haven't started active dev work with the new template, so I'm not really counting it yet.

Neither. I've been using ASP.Net Webforms for 15 years but am still learning lots. I've never come across anything I needed to do with it that I couldn't. I'm at an age where I'm not about to start learning a complete new paradigm, library, framework...
It's unlikely that I'll be starting any new projects at this point, other than "hobby" or personal projects, and for them WebForms will do the job admirably. However I do acknowledge that as Microsoft has declared there will be no further development on the WebForms front and that there will be no extensions to .Net Framework, it's inevitable that "the world" will move away from it to .Net core and MVC. I've just finished a task working on a Classic ASP site running on Windows 2003. Yes, it's in production and it is a core Line-of-Business application. Software hangs around for a lot longer than we might like, and that works in two ways. First it means that support for WebForms is unlikely to disappear any time soon; currently most Windows hosting companies support Classic ASP and ASP.Net Webforms, whilst only a minority have .Net Core fully available. So in one respect I'd have no worries about building a new WebForms application, on the assumption that "most" websites only last around 5 - 10 years or less before a rewrite. However my recent experience confirms that some can last a lot longer than that, and I'd be wary not so much about lumbering a client with a technically obsolete application, but rather leaving them with one that no-one could - or more to the point would - provide support for. And that is the crunch issue, really. There are lots of developers who know Classic ASP, for instance - but very few who are willing to take on Classic ASP projects, because they don't add to the CV, they don't build new skills, they don't give the buzz that being at the "cutting edge" brings.
So as others have said - "it depends". I don't know the detail differences between the options you give, but the same considerations apply. What is the realistic lifetime of the application? Is it for a 3rd party who might need to find alternative support in the future? Where is it to be hosted? Plus other commercial considerations - is choosing .Net Core at this time limiting the potential hosting options, and therefore a potentially more expensive solution? Is there a learning curve for the developer(s) that will extend development timescales and costs, potentially negating the project's benefits?
You're "just curious", but I suspect you have a potential project in mind. Just apply the usual technical and commercial criteria that you would normally use for determining the best implementation route.
