Description

ThreadImporter demonstrates importing and displaying still images on separate threads. For demonstration purposes only, this sample will also allow the use of non-thread safe components on separate threads.

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 applications main thread to forestall blocking the user interface.

Note:

This sample will NOT run on Mac OS X 10.2.x (Jaguar) even with QuickTime 6.4 installed.
