IAMTimeline::GetDefaultFPS 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 GetDefaultFPS method retrieves the default output frame rate, in frames per second (FPS). Groups use this value as their default frame rate. To set a group's frame rate, call the IAMTimelineGroup::SetOutputFPS method on the group.
