You are missing some Flash content that should appear here! Perhaps your browser cannot display it, or maybe it did not initialise correctly.
The sound that is playing with this movie is being streamed using the loadSound() function. It is using the base parameter to make sure that the Flash player finds it in the right place.
The ActionScript that enables this is:
// declare a new sound object
mysound = new Sound();
// load the audio into mysound, streaming mode
mysound.loadSound("Maple-Leaf-Rag.mp3", true);
// when the audio finishes the first time through start it again, with 999 loops!
mysound.onSoundComplete = function() {
mysound.start(0,999);
};Within flash node the base parameter is simply /files.
So when the Flash player finds a reference to loadSound with an unqualified path it uses the base parameter to work out where things really are.
For more information about using loadSound, loadMovie and the base parameter refer to the flash node documentation at drupal.org.
