This chapter provided you with an introduction to the AV Foundation framework. You should now have a better understanding of where it fits into Apple’s media environment and the capabilities it provides. You also now have a better understanding of the digital media domain itself. Although AV Foundation enables you to build some powerful applications without getting too deeply involved in the details of the media, you’ll definitely find that the more you understand about the domain, the easier it is to build the applications you desire. AV Foundation is the future of media on Mac OS X and iOS, and this book provides a hands-on guide showing you how to successfully use the framework to build the next generation of media applications.
