== UPDATE ==

So I just found out that Claus Wahlers has an awesome, more feature complete version of an AS3 SWF parser. It’s also available on GitHub. I’m still going to keep SwfData up since it’s much more specific to getting the background color of the swf. If you need more features, use as3swf by Claus, it’s very well done.
