Splits a timeline object in Microsoft® DirectShow® Editing Services (DES). Sources, effects, transitions, and tracks implement this interface.
Requirements
Requires Qedit.h.
Methods in Vtable Order
IUnknown methods Description QueryInterface Retrieves pointers to supported interfaces. AddRef Increments the reference count. Release Decrements the reference count. IAMTimelineSplittable Methods Description SplitAt Splits the object at the specified time. SplitAt2 Equivalent to SplitAt, but takes a REFTIME value.
IAMTimelineSplittable Interface
Splits the object at the specified time.
Syntax
HRESULT SplitAt( REFERENCE_TIME Time );
Parameters
- Time
- Time at which to split the object, relative to the start of the object, in 100-nanosecond units.
Return Value
Returns an HRESULT value. Possible values include the following:
S_FALSE Nothing to split. S_OK Success. E_INVALIDARG Invalid argument. E_OUTOFMEMORY Insufficient memory.
Remarks
If you split a source, effect, or transition, this method creates a second object of the same type. The original object is truncated at the specified split time, and the new object replaces the truncated portion. The new object inherits all of the same properties. In a source object, the method also splits any effects that fall on the split time.
Calling this method on a track splits all the sources, effects, and transitions that are contained in the track at the specified split time. It does not create a second track. (A track begins at time zero and extends to infinity.) If the split time is later than everything in the track, the method returns S_FALSE.
IAMTimelineSplittable Interface
Splits the object at the specified time. This method is equivalent to SplitAt, but takes a REFTIME value.
Syntax
HRESULT SplitAt2( REFTIME Time );
Parameters
- Time
- Time at which to split the object, relative to the start of the object, in seconds.
Return Value
Returns an HRESULT value. Possible values include the following:
S_FALSE Nothing to split. S_OK Success. E_INVALIDARG Invalid argument. E_OUTOFMEMORY Insufficient memory.
