[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetMediaTime method sets the media times for this sample.

Syntax

HRESULT SetMediaTime(
  [in] LONGLONG *pTimeStart,
  [in] LONGLONG *pTimeEnd
);

Parameters

[in] pTimeStart

Pointer to the beginning media time.

[in] pTimeEnd

Pointer to the ending media time.

Return value

Returns S_OK, or an HRESULT value indicating the cause of the error.

Remarks

To invalidate the media time, set pTimeStart and pTimeEnd to NULL. This will cause the IMediaSample::GetMediaTime method to return VFW_E_MEDIA_TIME_NOT_SET.

For more information about media times, see Time Stamps.
