To record video from webcam I've used following code in matlab 2015:
clear all;
clc;
vid = videoinput('winvideo',1, 'YUY2_640x480');
set(vid, 'FramesPerTrigger', Inf);
set(vid, 'ReturnedColorspace', 'rgb');
vid.FrameGrabInterval = 1;
start(vid)
aviObject = VideoWriter('myVideo.avi');
for iFrame = 1:100
I=getsnapshot(vid);
F = im2frame(I);
aviObject = addframe(aviObject,F);
end
aviObject = close(aviObject);
stop(vid);
But it seems to be working but following error resulted:
Error using imaqdevice/getsnapshot (line 65) A timeout occurred during GETSNAPSHOT.
Error in recording_video (line 17) I=getsnapshot(vid);
What is the problem?

Are you able to preview() the webcam?
Is the timeout appearing on the first frame, or after several have been captured?

Instead of adding the frame each time to the aviObject, have you tried attaching the VideoWriter to the videoinput object?
