Effective frame rate.
Declaration
property CurrentFrameRate: Double read GetCurrentFrameRate;
__property double CurrentFrameRate=read=GetCurrentFrameRate
Property CurrentFrameRate As Double
Description
Retrieves the effective frame rate, that can differ from the FrameRate that has been set.
Useful to know when the FrameRate property cannot be set, e.g. with video capture devices that have a fixed frame rate depending of the video format (e.g. like DV sources).
Note that some video capture devices accept any stupid value and return this stupid value even if they limit this value to an acceptable value.
