+ @discussion
+ Camera intrinsic matrix is a CFData containing a matrix_float3x3, which is column-major. Each element is in IEEE754 native-endian 32-bit floating point. It has the following contents:
+ fx s cx
+ 0 fy cy
+ 0 0 1

- @discussion A video packing can be one of several types including frame-packing for stereo views or texture atlasing. A CMTag having a CMTagCategory of kCMTagCategory_ProjectionType has a value that is an OSType indicating the kind of packing using a kCMPackingType_* constant. Examples of frame-packing include side-by-side and over-under packing, There may be related CMTags if a kind of packing requires additional parameters. The requirements will be documented with the specific kind of packing.

@constant kCMPackingType_None There is no packing. This is a traditional 2D texture. For this case no packing tag needs to be used.
@constant kCMPackingType_SideBySide The packing uses a horizontal side-by-side packing of two views. By default, the left stereo eye view is to the left of the right stereo eye view. If the view order is reversed, indicated by kCMTagCategory_StereoViewInterpretation/kCMStereoViewInterpretation_StereoOrderReversed, then the right view is to the left of the left stereo view.
@constant kCMPackingType_OverUnder The packing uses a vertical over-under (or top-and-bottom) packing of two views. By default, the left stereo eye view is above the right stereo eye view. If the view order is reversed, indicated by kCMTagCategory_StereoViewInterpretation/kCMStereoViewInterpretation_StereoOrderReversed, then the right view is above the left stereo view.
