ThreadsExportMovie

Last Revision:	Version 1.0.2, 2006-01-03 Removed specific check for progressOpExportMovie in the movie export progress procedure which caused premature export termination with QT 7.0.3+.
Build Requirements:	Xcode 2.1+ (for Universal Binary), Xcode 1.0 or later.
Runtime Requirements:	Mac OS X 10.4.x, Mac OS X 10.3.x with QuickTime 6.4 or later.

ThreadExportMovie is a Cocoa sample which demonstrates exporting Movies using the QuickTime Movie Export Component on separate threads. Xcode 2.1 Project builds universal binary. Note: This sample requires Xcode 1.0 or later, Mac OS X 10.3 (Panther) or later with QuickTime 6.4 or later. It will not run on Mac OS X 10.2.x (Jaguar) even with QuickTime 6.4. QuickTime 6.4 (on MacOS X 10.3 and later) introduces several new features that support execution of background tasks on multiple threads in a preemptive multitasking environment. This makes it possible to offload many tasks from your program's main thread to forestall blocking the user interface.
