IPin::NewSegment

Windows CE .NET

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

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 Values

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 any new data. It indicates that all data arriving after this call is part of a segment delineated by the parameters.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
