roi_stream error

Thanks for sharing the great tool. There are some errors when running the individual and batch location tracking. Here shows individual errors. Details see attached PDF. Thanks.

For the individually processed video, in cell 2 you have region names set to ["left","right","top","bottom"], but you don't define their location. This will cause an error. If you do not intend to use regions of interest, it must be set to None.

For the batched processed video, you ran the cell to set the distance scale (where it says 'Select Points'), but I don't see any points selected. If you run this cell but don't select any points it will cause an error.

Thanks. It works.
