Introducing a delay

[cowboyd]

Hi there,

I'm using camtwist to broadcast live streams of video games as they are in progress. I was wondering if there was a way to introduce an arbitrary delay to the live stream so that it cannot be used for cheating.

Would it be possible to do this with a custom effect?

Yup

Ok. I would rate myself as a strong ruby,java,python developer with absolutely zero ObjectiveC experience and just as much experience with cocoa. Given that I don't have a development environment set up to write/compile/debug cocoa, how difficult would it be to jump in and write this effect myself?

Well there are at least 2 ways to proceed. You could certainly do it with Obj-C, and that's how I would do it but only because that's what I am most familiar with. You could also attempt to do it with Quartz Composer. QC is a really powerful tool that lets you create graphical compositions. It's hard to describe in a few sentences but think about a toolbox where you can drag out various tools (patches) and connect the patches together like a pipeline. If you get into it, you might find that it's not practical with QC but keep in mind that I don't fancy myself a QC expert. I know just enough to do the basic stuff.

That being said, Obj-C/Cocoa is a really great programming language/environment. If you're strong with Java, I imagine you'd pick up the basics pretty quickly. From there, I could send you a Hello World CamTwist plugin and help you get it going.

Do you know C?
