property TestMode: TRVBoundsTestMode;
rvstmChangedFragments may be used if Encoding=rvet*Change. In this mode, instead of sending changed fragments, the component sends special test images, where changed pixels are shown, and changed areas (matching MinChangeAreaSize property) are framed with rectangles. This mode can be useful to find the optimal values of MinChangeAreaSize and PixelColorThreshold properties for the given video source.
