[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 EnableTransitions method enables or disables all transitions in the timeline. If transitions are disabled, the render engines treats them as cuts; that is, the rendered output jumps instantly from one track to the next. The default cut point is halfway through the duration of the transition. You can change the cut point by calling the IAMTimelineTrans::SetCutPoint method on the transition. Disabled transitions are not removed from the timeline.
HRESULT EnableTransitions(
BOOL fEnabled
);-
fEnabled
-
Boolean value that specifies whether to enable or disable transitions. If TRUE, transitions are enabled. If FALSE, transitions are disabled.
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
