Can someone please explain how does the parameter usePrevious (from the function fcvTrackBMOpticalFlow16x16u8) work? The documentation says "it indicates if the function should use the existing motion vectors in locX and locY as the starting point for motion vector search", but I couldn't make it work. I'm looking for a way to search blocks in src1 around different starting point in src2.

This parameter is redundant and the functionality was not implemented. Sorry for oversight in function header documentation.

Thank. So basically, there's no option to explicitly set the starting point for motion vector search?
