CTransformFilter.NewSegment method

  • Článek

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 filter that media samples received after this call are grouped as a segment.

Syntax

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

Parameters

tStart

Start time of the segment, relative to the original source.

tStop

Stop time of the segment, relative to the original source.

dRate

Rate at which the segment should be processed.

Return value

Returns S_OK.

Remarks

The input pin's CTransformInputPin::NewSegment method calls this method. This method delivers the NewSegment call to the downstream input pin.
