CMediaType provides a C++ class object containing the media type data structure and methods that provide access to each of the members of the structure.

CRefTime provides a C++ class object containing the methods used to access the reference time, and operators used to perform Boolean tests or arithmetical operations on two CRefTime objects.

FOURCCMap provides conversion between the older-style FOURCC media tags used to identify and register media types and the GUID media subtypes used by DirectShow.
