The SetStartStop method sets the object's start and stop times, relative to the object's parent.
Syntax
HRESULT SetStartStop(
REFERENCE_TIME Start,
REFERENCE_TIME Stop
);
Parameters
Start
New start time, in 100-nanosecond units, or –1 to keep the existing start time.
Stop
New stop time, in 100-nanosecond units, or –1 to keep the existing stop time.
Return Value
Returns one of the following HRESULT values:
| Return code | Description |
| S_OK | Success. |
| E_INVALIDARG | Invalid argument. |
| E_NOTIMPL | Not implemented. |
Remarks
Tracks, compositions, and groups do not implement this method. For these objects, the start time is always zero, and the stop time is the maximum stop time of the objects they contain.
Do not set overlapping times on source objects within the same track. Doing so can cause undefined behaviors.
For source objects, the start and stop times are independent of the media start and media stop times. Changing one pair of values does not change the other. To set the media start and stop times, call the IAMTimelineSrc::SetMediaTimes method. For more information, see Time in DirectShow Editing Services.
