Live Broadcasting Game Show

[Boogerlad]

Hello all. I'm wondering if it's possible to accept live input from a webcam/camera/camcorder connected via usb, and add human controllable overlays like the ones in the game show "Who Wants to Be a Millionaire?" I'm not sure if avisynth is the right software to do this, and if it isn't does anyone have a suggestion?

anyone?

That does not sound like something avisynth is well suited for.

I didn't chip in earlier as others are more knowledgable than me, but as I understand it the main problem is that AviSynth is designed for random, rather than sequential, access. To that end, AviSynth can only generate output of a fixed length. I guess in theory you could write some kind of input filter that returned an extremely long clip and populated frames with the latest capture from the USB card, but you'd be hard pushed to get a great result - frames would be dropped/duped, for example, because you can't guarantee that the AviSynth clip and the video input are in sync.

If it helps your Googling, such systems are sometimes called Astons in the industry.
