Questions tagged [qtkit]

The QuickTime Kit is an Objective-C framework (QTKit.framework) with an API for manipulating time-based media.

QuickTime Kit (aka QTKit) is a developer framework that is intended to replace previous APIs for Cocoa developers. This framework is for Mac only, and exists as Objective-C abstractions around a subset of the C interface. Mac OS X v10.5 extends QTKit to full 64-bit support. The QTKit allows multiplexing between Quicktime X and Quicktime 7 behind the scenes so that the user need not worry about which version of Quicktime they need to use.
