Webcam Video

I was told that there’s absolutly no way possible for Flash MX 2004 to find the location of movement through a webcam.

I’d like to know if this is true or not. I’ve looked on google for about 4 hours looking to see if there’s any possible way and that just made matters worse, because people said it could be done, but never gave links or examples…

So please, can someone put this to bed for me so I can stop searching?

TIA.
