Note from the Author or Editor:
The version of OSMF used in the book is 0.9 which builds properly. Since the release of the book 1.0 has been released and may have slightly different named variables, though 0.9 was slated as being api complete and locked down.

OSMF 1.0 comes with plenty of samples including use of the CaptioningPlugin. It can be found at http://opensource.adobe.com/wiki/display/osmf/downloads

The class Application no longer exist in Flex 4.
This line creates fatal error :
var parameters : Object = Application.application.parameters;

It should be :

Please try to test your codes before update your books?
