Matlab code for capturing video from webcam

Following is the Matlab Code for Capturing video from local webcam on computer and storing captured video, video frames to local storage on System.

 my_log = 'c:/tempfiles/videotest/test2.avi';        aviobj = avifile(my_log, 'compression','Cinepak','fps',10,'quality',100);        vid = videoinput('winvideo',1,'YUY2_640x480');         set(vid, 'ReturnedColorSpace', 'rgb');        %vid.LoggingMode = 'disk&memory';        vid.TriggerRepeat = Inf;            set(vid,'FramesPerTrigger', 50);        start(vid);                     i=0;         outputFolder = fullfile(cd, 'frames');        if ~exist(outputFolder, 'dir')        mkdir(outputFolder);        end;         while 1        i=i+1;                img=getsnapshot(vid);        %either use preview or image        image(img);        pause(0.01);        aviobj=addframe(aviobj,img);        img = imresize(img, (1/2));        outputBaseFileName = sprintf('%d.png',i);        outputFullFileName = fullfile(outputFolder, outputBaseFileName);        imwrite(img,outputFullFileName,'jpg');                                                        %managing memory        out = imaqmem;        mem_left = out.FrameMemoryLimit - out.FrameMemoryUsed;        half_of_memlimit=(out.FrameMemoryLimit/2);        if mem_left < half_of_memlimit            flushdata(vid,'triggers'); %each flushes only 50 frames            flushdata(vid,'triggers');        end;         end;
