The GetStartStop method retrieves the object's start and stop times, relative to the object's parent.
Syntax
HRESULT GetStartStop(
REFERENCE_TIME *pStart,
REFERENCE_TIME *pStop
);
Parameters
pStart
Pointer to a variable that receives the start time, in 100-nanosecond units.
pStop
Pointer to a variable that receives the stop time, in 100-nanosecond units.
Return Value
Returns S_OK if successful, or E_POINTER otherwise.
Remarks
Compositions, groups, and tracks always have a start time of 0.
During rendering, DES rounds an object's start and stop times to the nearest frame boundary. However, DES does not overwrite the object's times. If you change the group frame rate, the rounded times are always calculated from the original times. For more information, Time in DirectShow Editing Services.
To determine the start and stop times in the rendered project, pass the values returned by GetStartStop to the IAMTimelineObj::FixTimes method.
