CBasePin.NewSegment 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 NewSegment method notifies the pin that media samples received after this call are grouped as a segment. Implements the IPin::NewSegment method.

Syntax

HRESULT NewSegment(
   REFERENCE_TIME tStart,
   REFERENCE_TIME tStop,
   double         dRate
);

Parameters

tStart

Starting media position of the segment, in 100-nanosecond units.

tStop

End media position of the segment, in 100-nanosecond units.

dRate

Rate at which this segment should be processed, as a percentage of the original rate.

Return value

Returns S_OK.

Remarks

This method sets the CBasePin::m_tStart, CBasePin::m_tStop, and CBasePin::m_dRate member variables. In your derived class, override this method to pass the notification downstream.
