So I have a big project in college and I couldn't run the optical flow example from the opencv source files... So I need a running code that does optical flow to an input from a camera. I also need help understanding the functions calcOpticalFlowPyrLK and goodFeaturesToTrack.

and if you could, please tell me what need to be changed in the optical flow exaple to make it run.

The code: https://docs.opencv.org/3.3.0/d2/d0a/...

the goodFeaturesToTrack error is that apparently opencv has 2 features by that are very similar and I can't know which one is needed and how to resolve it
