CEnumMediaTypes class

CEnumMediaTypes Class Hierarchy

The CEnumMediaTypes class implements an enumerator for preferred media types.

This class implements the IEnumMediaTypes interface. It calls the following CBasePin methods:

Whenever a pin alters its list of preferred media types, the pin increments the media-type version number. When this happens, the enumerator object is no longer synchronized with the pin, and the class methods return VFW_E_ENUM_OUT_OF_SYNC. Call the CEnumMediaTypes::Reset method to resynchronize the enumerator.
