IAMTimecodeDisplay 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IAMTimecodeDisplay interface controls an external SMPTE/MIDI timecode display device.

DirectShow currently does not provide any filters that implement this interface. Third parties should implement this interface on any filter that controls the timecode display of an external timecode reader or generator. Timecode readers or generators can be built into a VCR or can be separate external devices.

This interface is not intended for rendering in a DirectShow filter graph; it is purely for use on external device displays.

Hardware Requirements

See the IAMExtTransport interface for hardware requirements.

Inheritance
