WMT_OFFSET_FORMAT enumeration (wmsdkidl.h)

  • Article

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The WMT_OFFSET_FORMAT enumeration type defines the types of offsets used in this SDK.

Syntax

typedef enum tagWMT_OFFSET_FORMAT {
  WMT_OFFSET_FORMAT_100NS = 0,
  WMT_OFFSET_FORMAT_FRAME_NUMBERS,
  WMT_OFFSET_FORMAT_PLAYLIST_OFFSET,
  WMT_OFFSET_FORMAT_TIMECODE,
  WMT_OFFSET_FORMAT_100NS_APPROXIMATE
} WMT_OFFSET_FORMAT;

Constants

 
WMT_OFFSET_FORMAT_100NS
Value: 0
An offset into a file is specified by presentation time in 100-nanosecond units.
WMT_OFFSET_FORMAT_FRAME_NUMBERS
An offset into a file is specified by frame number.
WMT_OFFSET_FORMAT_PLAYLIST_OFFSET
An offset of playlist entries.
WMT_OFFSET_FORMAT_TIMECODE
An offset into a file is specified by presentation time as identified by SMTPE time codes.
WMT_OFFSET_FORMAT_100NS_APPROXIMATE
Used to specify approximate seeking. This type of offset seeks to the closest key frame prior to the time specified.

Remarks

WMT_OFFSET_FORMAT is used as an input parameter to IWMReaderAdvanced3::StartAtPosition. The value passed specifies whether the reader should begin playback at a specified presentation time, frame number, or offset into a playlist.

Minimum supported client Windows 2000 Professional [desktop apps only],Windows Media Format 9 Series SDK, or later versions of the SDK
