error in video recording on a windows

clear all; %% clear all privious variables

clc;

close all

cam = webcam('Integrated Webcam')

vid = videoinput('winvideo',1);

set(vid, 'FramesPerTrigger', Inf);

set(vid, 'ReturnedColorspace', 'rgb');

% vid.FrameRate =30;

vid.FrameGrabInterval = 1; % distance between captured frames

%start(vid)

aviObject = VideoWriter('myVideo.avi'); % Create a new AVI file

open(aviObject)

for iFrame = 1:150 % Capture 150 frames

% ...

% You would capture a single image I from your webcam here

% ...

I=getsnapshot(vid);

%imshow(I);

F = im2frame(I); % Convert I to a movie frame

writeVideo(aviObject,F); % Add the frame to the AVI file

pause(0.1)

end

close(aviObject); % Close the AVI file

stop(vid);

But I keep getting this error: Error using videoinput (line 532)

winvideo: Image acquisition device is not accessible.

Insufficient system resources exist to complete the requested service.

Make sure no other objects or applications are accessing the same device.

Error in AcquireVideo (line 11)

vid = videoinput('winvideo',1);

Hi Ana,

As per my understanding, you have to install the support packages for Image accquisition toolbox adapters.

If the usb webcam doesnt wanna install winvideo, I would recommend you to install Image Acquisition Toolbox Support Package for "OS Generic Video Interface".

Refer to these Link for more information.
