DEXTERF_TRACK_SEARCH_FLAGS enumeration

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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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

Note

[Deprecated. This API may be removed from future releases of Windows.]

The DEXTERF_TRACK_SEARCH_FLAGS enumeration specifies the boundary conditions on a search for an object in the timeline.

Syntax

typedef enum  { 
  DEXTERF_BOUNDING    = -1,
  DEXTERF_EXACTLY_AT  = 0,
  DEXTERF_FORWARDS    = 1
} DEXTERF_TRACK_SEARCH_FLAGS;

Constants

DEXTERF_BOUNDING Start <= TimeStop > Time
DEXTERF_EXACTLY_AT Start == Time
