<< Click to display table of contents >> TRVCamMultiView.RefreshRate

Specifies how often the control can be redrawn when playing videos.

property RefreshRate: Integer;

If RefreshRate = 0, the component is redrawn when receiving each new video frame. While in VCL version the component draws new video frames directly on its canvas (without redrawing other its parts), in LCL and FireMonkey the whole control is redrawn (with CllipRect optimization, if possible), and displaying a large count of videos may be inefficient.

If RefreshRate > 0, it defines the maximum count of repaints in a second. In this mode, the component checks periodically for updated video viewers, and redraws itself if necessary (with CllipRect optimization, if possible). This mode is efficient for displaying a large count of videos, especially in LCL and FireMonkey.
