IAMTimelineTrack::GetNextSrcEx 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 GetNextSrcEx method retrieves the next source after the specified source.

Syntax

HRESULT GetNextSrcEx(
        IAMTimelineObj *pLast,
  [out] IAMTimelineObj **ppNext
);

Parameters

pLast

Pointer to the previous source object, or NULL to retrieve the first source in the track.

ppNext [out]

Receives a pointer to the next source object's IAMTimelineObj interface.

Return value

Returns S_OK if the method retrieves a source, or S_FALSE otherwise.

Remarks

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.
