Apple's QuickTime multimedia architecture has some features that can be exploited through server-side scripting and HTML embedding, but it's something of a black art. There is confusion and inconsistency in how best to embed QuickTime in Web pages, deal with QTVR, let movies talk to each other, pass XML QTLists back and forth between movies and servers, and much more. PEAR::QuickTime hopes to expose this in a clean and elegant way so that QuickTime can reach the audience it deserves. It aims to provide a simple and consistent interface to these features through a set of PEAR-compatible PHP classes and functions.
