IMpeg2Demultiplexer interface (strmif.h)

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

This interface is implemented on the MPEG-2 Demultiplexer filter (Demux) and is used in both program stream mode and transport stream mode. It is called by applications or other filters to create, configure and delete output pins on the Demux. This interface is not exposed when the filter is playing back a file (pull-mode).

Inheritance
