How do I connect a VGA input to my Mac?

Question

I am not talking about connecting a VGA monitor to a Mac. I'm referring to plugging in a VGA output in to my Mac. I want the VGA to show up as a video device, so that I can run a projector's feed through UStream.

What hardware is needed to digitize a VGA input in real time to send for broadcast?

Answer 1

You need a product like this:

KVM Console to USB 2.0 Portable Laptop Crash Cart Adapter

However I don't know if that will show up as a streamable device (or if it's even compatible with Mac). There are also people who have had success buying a webcam and a VGA > Analogue adapter, and wiring the analogue adapter into the webcams electronics to get it back into the computer.

Unfortunately, no real "easy" solution exists.

Answer 2

I use a product from http://xlr8.com/ to give me a video input on my mac, then use a VGA-to-TV adapter to stream powerpoint over ustream. Video is really choppy and crappy looking, but for simple non-moving slides, it's OK for ustream.
