IVPManager interface (strmif.h)

  • Article

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]

The IVPManager interface is implemented on the Video Port Manager (VPM). The interface provides methods for applications to specify and retrieve indexes for ports when there are multiple video ports on a system, and to specify and retrieve the rectangle used by the video port. Currently, only the two index-related methods are implemented.

Inheritance

The IVPManager interface inherits from the IUnknown interface. IVPManager also has these types of members:
