IAMTimelineComp::VTrackSwapPriorities 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 VTrackSwapPriorities method switches the priority levels of two tracks.
Given two priority levels, this method switches the virtual tracks at those priorities. When the method returns, the track that was at the first priority level is now at the second priority level, and vice versa.
