IMediaSample::SetTime method (strmif.h)
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetTime method sets the stream times when this sample should begin and finish.
Syntax
HRESULT SetTime(
[in] REFERENCE_TIME *pTimeStart,
[in] REFERENCE_TIME *pTimeEnd
);
Parameters
[in] pTimeStart
Pointer to a variable that contains the start time of the sample.
[in] pTimeEnd
Pointer to a variable that contains the stop time of the sample.
Return value
Returns S_OK, or HRESULT value indicating the cause of the error.
Remarks
Both time values are relative to the stream time. For more information, see Time and Clocks in DirectShow.
To invalidate the stream times, set pTimeStart and pTimeEnd to NULL. This will cause the IMediaSample::GetTime method to return VFW_E_SAMPLE_TIME_NOT_SET.
For more information about stream times, see Time and Clocks in DirectShow.
