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 |

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.
