Auto Thumbnailing Embedded Flash Videos

I searched around but was unable to find anything. I’m not sure if it’s because I’m not searching the right thing or people haven’t been setting this up.

Is there a way to automatically capture screenshots from embedded videos?

Like when you embed a YouTube, Google Video video on your site, are you able to somehow auto grab the screenshot from video you just embedded. I know there are APIs that Youtube and other services offered. We’re looking for something we can build locally and cap while still embedding the videos.

Not sure if that makes sense. Any info would be great.
