CMediaSample.SetTime method

  • 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetTime method sets the stream times when this sample should begin and finish. This method implements the IMediaSample::SetTime method.

Syntax

HRESULT SetTime(
   REFERENCE_TIME *pTimeStart,
   REFERENCE_TIME *pTimeEnd
);

Parameters

pTimeStart

Pointer to the stream time at which the sample begins, in 100-nanosecond units, or NULL.

pTimeEnd

Pointer to the stream time at which the sample ends, in 100-nanosecond units, or NULL.

Return value

Returns S_OK.

Remarks

This method sets the CMediaSample::m_Start and CMediaSample::m_End member variables, which specify the time stamps. It also updates the CMediaSample::m_dwFlags member variable, which specifies whether the time stamps are valid.

For information about time stamps, see Time and Clocks in DirectShow.
