IEnumMediaTypes interface

The IEnumMediaTypes interface enumerates a pin's preferred media types. To obtain this interface, call the IPin::EnumMediaTypes method on the pin. Filters use this interface when they connect to other filters. Applications can also use it to examine a pin's preferred media types. For more information, see Enumerating Objects in a Filter Graph.

This interface implements a standard Component Object Model (COM) collection object.

If a pin's set of preferred media types changes, some methods on this interface return VFW_E_ENUM_OUT_OF_SYNC. Call the IEnumMediaTypes::Reset method to resynchronize the enumerator.
