IWMSyncReader2::SetRangeByTimecode method (wmsdkidl.h)

[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 It has been superseded by Source Reader and Sink Writer.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 SetRangeByTimecode method sets a starting and ending time, based on SMPTE time codes, for playback of a file.

Syntax

HRESULT SetRangeByTimecode(
  [in] WORD                        wStreamNum,
  [in] WMT_TIMECODE_EXTENSION_DATA *pStart,
  [in] WMT_TIMECODE_EXTENSION_DATA *pEnd
);

Parameters

[in] wStreamNum

WORD containing the stream number.

[in] pStart

Pointer to a WMT_TIMECODE_EXTENSION_DATA structure containing the starting time code.

[in] pEnd

Pointer to a WMT_TIMECODE_EXTENSION_DATA structure containing the ending time code.

Return value

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Remarks

For the method to succeed, the file must be indexed by SMPTE time code.

If the call is successful, all streams are synchronized to the same position based on presentation time.
