IAMTimelineTransable::GetNextTrans 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 GetNextTrans method retrieves the first transition that appears at the specified time or later.

Syntax

HRESULT GetNextTrans(
  [out] IAMTimelineObj **ppTrans,
        REFERENCE_TIME *pInOut
);

Parameters

ppTrans [out]

Receives a pointer to the transition object's IAMTimelineObj interface.

pInOut

Pointer to a variable that specifies the time in 100-nanosecond units. On input, this value specifies the time from which to find the transition. On output, if a transition is retrieved, this value is set to the stop time of the transition.

Return value

Returns S_OK if the method retrieves a transition, or S_FALSE if it does not find a transition. Otherwise, returns an HRESULT value indicating the cause of the failure.

Remarks

The start time of the transition might be less than the time that you specify in pInOut, if the transition spans the specified time.

If the method returns S_OK, the IAMTimelineObj interface that it returns has an outstanding reference count. Be sure to release the interface when you are finished using it.
