The SimplePlayer Application

As discussed in the last chapter, using these APIs is the best way to get a feel for them. To demonstrate QuickTime, look at the SimplePlayer example. This player can load and play a variety of media formats, including QuickTime movies and MP3 audio files. Additionally, the application allows you to export files to other formats, demonstrating that facet of the QuickTime API. As they are put to use in SimplePlayer, try to recognize the key classes and methods from the last section.

The source for this application, shown in Example 10-1, is surprisingly concise. Much of this code is actually spent in setup and user interface. The actual QuickTime APIs used are fairly simple to understand.
