QuickTime for Java: A Developer's Notebook

Playing Movies from URLs

Along with loading movies from disk, QuickTime can also load them from URLs, and is pretty smart about network latency.

How do I do that?

Example 2-6 shows a totally new class, BasicQTURLController.java. This is a significant rethinking of the earlier BasicQTController class. This example creates a GUI from an empty “dummy” movie, then asks the user for a URL, gets a Movie from that, and replaces the dummy movie. By getting the movie last, it tempts fate to see how well QTJ can deal with loading a movie over the network.
