IEnumPIDMap interface

The IEnumPIDMap interface enumerates a collection of Packet ID (PID) maps. Each PID map describes how the MPEG-2 Demultiplexer filter maps a PID to an output pin on the filter. PID mappings are created by calling the IMPEG2PIDMap::MapPID method on the filter's output pin.

To obtain the IEnumPIDMap interface, call the IMPEG2PIDMap::EnumPIDMap method on the output pin. Typically, output pins for audio and video streams have at most one PID mapped at any given time.

This interface implements a standard Component Object Model (COM) collection object. The collection object represents a snapshot of the PID map when the collection is created. The collection is not updated automatically.
