AS3 determine differnce between animated and not-animated gif?

Is there a way in AS3 to开发者_如何转开发 determine the difference between animated and not-animated gif?

The native Flash Player does NOT support animated GIFs. However someone has written a library that does, so you could use that library to read in the file, and count the number of frames. 1 frame = non animated. More than 1 frame = animated.
