But I get error:
Error using videoinput (line 391) winvideo: The device associated with device ID 1 is already in use. A new videoinput object cannot be created for this device while it is in use.
Error in trck_movng_obj (line 2) vid = videoinput('winvideo',1,'YUY2_160X120');
Can somebody tell me how to solve it ? please

I was having the same problem. but i was able to solve it. Used the following code:
clc; clear;
close all; objects = imaqfind %find video input objects in memory
delete(objects) %delete a video input object from memory
vid=videoinput('winvideo',2,'MJPG_1280x720'); preview(vid)
now whenever i run the code, it will detect the winvideo input and show the preview.

Make sure nothing else is using it. I'm not sure how to tell what else is using it if you don't already know, like you have your webcam manufacturer's app running, or webex running or whatever.
