zooming is used to indicate the moving direction, and zs is used to indicate the speed. 
To stop a continuous movement, you have to use the command as below:

2. [Area zoom]: it means to zoom in on a specific area, here is an example for a directly moving 
[x, y] is the desired coordinate, and it will be the center after movement 
[w, h] is the scaled area size 
[resolution] is the base range of this coordinate system 
The example shows [w, h] = [864, 488], which means to zoom in to ratio x2.2 based on [1920x1080]. 
Pay attention to that [x, y, w, h] are essential parameters in an area zoom case, and the stream index is counted 
from 0 as the first stream.
