IRenderEngine::GetTimelineObject 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 GetTimelineObject method retrieves the timeline that the render engine is currently using.
Syntax
HRESULT GetTimelineObject(
[out] IAMTimeline **ppTimeline
);
Parameters
-
ppTimeline [out]
-
Receives a pointer to the timeline's IAMTimeline interface. It receives the value NULL if there is no timeline.
Return value
Returns one of the following HRESULT values:
| Return code | Description |
|---|---|
|
Success. |
|
Invalid pointer. |
|
Render engine failed to initialize. |
Remarks
On return, if the value of *ppTimeline is non-NULL, the IAMTimeline interface has an outstanding reference count. Be sure to release the interface when you are finished using it.
