IAMTimelineSplittable::SplitAt method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Note
[Deprecated. This API may be removed from future releases of Windows.]
The SplitAt method 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 timeline, in 100-nanosecond units.
Return value
Returns an HRESULT value. Possible values include the following:
| Return code | Description |
|---|---|
|
Nothing to split. |
|
Success. |
|
The object does not exist at this time. |
|
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.)
For a track, if the split time is later than everything in the track, the method returns S_FALSE. For any other object, if the split time does not fall anywhere within the object, the method returns E_INVALIDARG.

The header file Qedit.h is not compatible with Direct3D headers later than version 7.
