Flash videos on sites always ask to put cookies on your computer, to store info for a particular site, or whatever. I regularly get the "s.ytimg.com" request and Deny it. I finally Googles it to see what's what, and was surprised at what I found:

video camera spying

I went through the settings in Flash before, and have always had the camera and mic access blocked to sites. It's crazy that YouTube, VEVO, or other sites asking to set cookies for one thing, could use this for another.

Excellent information. Thanks for posting it.
