IMFTopologyServiceLookup interface

Enables a custom video mixer or video presenter to get interface pointers from the Enhanced Video Renderer (EVR). The mixer can also use this interface to get interface pointers from the presenter, and the presenter can use it to get interface pointers from the mixer.

To use this interface, implement the IMFTopologyServiceLookupClient interface on your custom mixer or presenter. The EVR calls IMFTopologyServiceLookupClient::InitServicePointers with a pointer to the EVR's IMFTopologyServiceLookup interface.
