This method specifies that samples following this method are grouped as a segment with a given start time, stop time, and rate.

Syntax

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

Parameters

  • tStart
    [in] Start time of the segment.
  • tStop
    [in] Stop time of the segment.
  • dRate
    [in] Rate of the segment.

Return Value

Returns an HRESULT value that depends on the implementation.

HRESULT can be one of the following standard constants, or other values not listed.

Value

Description

E_FAIL

Failure.

E_POINTER

Null pointer argument.

E_INVALIDARG

Invalid argument.

E_NOTIMPL

Method is not supported.

S_OK or NOERROR

Success.

Remarks

This method enables filters that process buffers containing more than one sample to delineate the rendering of the samples between start and stop time, as indicated by the tStart and tStop parameters.

This method is intended to be implemented on an input pin.

A connected output pin on the upstream filter calls this method after completing delivery of previous data and before calling IMemInputPin::Receive with new data. It indicates that all data arriving after this call is part of a segment delineated by the parameters.
