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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.
