Which values for window size and number of pyramids are reasonable for calcOpticalFlowPyrLK?

Assume a mobile android application, processing video frames real-time, which can have a certain degree of camera motion.

Do any remaining parameters need some tweaking?

In the past (2.3.1 - 2.4.0 versions) I did fine with window sizes about 21x21 - not sure which pyramid levels i was using, i guess it was the default ones.

Right now (2.4.1 +), to have reasonable results i need window sizes ~ 41x41 and about 2 pyramid levels.
