I need to build pretty easy interactive motion graphic, where I need to display live "webcam window".
It should be a usb webcam connected to same computer where the presentation is running.
I spent two days of searching over the internet, but no luck.
Also, I was thinking about creating graphics with transparent square and leave "webcam window" behind the presentation, which can do the trick, bat as of now I did not find a way to make stage transparent to be able to see applications (or desktop) behind.
Is there some way how to achieve this or should I aim to Flash?
Thank you for your time.
Flash is one option, as is a Flash file hosted in Director if you need to extend the basic capability of Flash.
Depending on your version of Director you might find an xtra (like TTC or Myron) that works for you - check the Mile High Table
I've done it a couple of times, I use the cxtraVideoCapture xtra from cxtras (http://www.cxtra.net/).
To make the stage transparant, you should use a mask, but with this xtra, you can just implement it in your director movie, so no need to make it more difficult than necessary!
I would suggest avoiding cXtras if possible: they are Windows-only, only work up to version 10 (not 11+ - and never will), and their support seems to have vapourised. Saying this I have licences for 3 of their products that are in active distribution.
