Does anyone out there know if there is a way to pull raw, still-compressed audio and video samples out of a Quicktime .mov file using an Apple API / Framework targeting the Mac that can be compiled natively in 64-bit (IE: QTKit)? I know this functionality is available in Apple's QuickTime Framework that targets the Mac, but this Framework can only be compiled under 32-bit.

如果任何人都熟悉这样一个框架和任何相关的样品code，一些有识之士将是非常美联社preciated。

If anyone is familiar with such a Framework and any related sample code, some insight would be much appreciated.
