Error in recording video using two logitech webcam simultaneously

I was able to record video using two webcam simultaneously. But now using same code I am getting error. It is saying that my device is in use but actually it is not. The error is:

Error using videoinput (line 391)

winvideo: The device associated with device ID 2 is already in use.  A new videoinput object cannot be created for this device while it is in use.

Error in recording_video1 (line 5)

vid2 = videoinput('winvideo',2, 'YUY2_320x240');

Try

vid2 = videoinput('winvideo',1, 'YUY2_320x240');

or

vid2 = videoinput('winvideo',3, 'YUY2_320x240');

or whatever number your second camera is.

I am using two logitech C170 webcam. For the first webcam it is

vid1 = videoinput('winvideo',1, 'YUY2_320x240');

and for the second camera it is

vid2 = videoinput('winvideo',2, 'YUY2_320x240');

when I use these webcam individually, each of them run properly. But when I try to use them simultaneously which is my requirement, I get the error as mentioned

Error using videoinput (line 391)

winvideo: The device associated with device ID 2 is already in use. A new videoinput object cannot be created for this device while it is in use.

Error in recording_video1 (line 5)

vid2 = videoinput('winvideo',2, 'YUY2_320x240');
