IAMTimelineTransable::TransAdd 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 TransAdd method adds a transition to the object. An object can have multiple transitions, but they must not overlap in time. Transitions must fall within the time boundaries of the object.

Syntax

HRESULT TransAdd(
   IAMTimelineObj *pTrans
);

Parameters

pTrans

Pointer to the IAMTimelineObj interface of the transition to add.

Return value

Returns one of the following HRESULT values:

Return code	Description
S_OK	Success.
E_INVALIDARG	Cannot insert the transition.
E_NOINTERFACE	pTrans is not a pointer to a transition.

 

Remarks

If the transition overlaps an existing transition, the method returns E_INVALIDARG.
