IStreamSample::SetSampleTimes method (mmstream.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]

Note This interface is deprecated. New applications should not use it.

Sets the current sample's start and end times. You can call this method prior to updating the sample.

Syntax

HRESULT SetSampleTimes(
  [in] const STREAM_TIME *pStartTime,
  [in] const STREAM_TIME *pEndTime
);

Parameters

[in] pStartTime

Pointer to a STREAM_TIME value that contains the sample's new start time.

[in] pEndTime

Pointer to a STREAM_TIME value that contains the sample's new end time.

Return value

Returns S_OK if successful or E_POINTER if one of the parameters is NULL.

Remarks

For streams that have a clock, the times must be relative to the stream's current time. If the stream doesn't have a clock, the times should be relative to the media.
