Public ReadOnly Property CurrentFrameRate As Double

C++/Qt

double GetCurrentFrameRate ();

Retrieves the effective frame rate, which 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 on the video format (e.g. DV sources). Note that some video capture devices accept any value, even a meaningless one, and report it back even though they internally limit it to an acceptable value.
