How to write a open cam loop?

Hey; I'm trying to converte a code from reading a video to open cam ; hope someone can help me.

   videoName = 'tt1.mp4';
    videoReader = VideoReader(videoName);
    timeStamp = 0.06667;                   % time from the beginning of the video
    videoReader.CurrentTime = timeStamp;   % point to the chosen frame
    rgbImage = readFrame(videoReader); % read frame at timeStamp seconds
    figure
    imshow(rgbImage) % display frame

What do you mean by "to open cam"? Do you have a machine vision camera or webcam installed? Those devices acquire images. What does that have to do with opening a video and extracting frames and displaying them from it like you are doing with your code?

Do you have the Image Acquisition Toolbox installed? Or the webcam add-on from the Add-on explorer?

I installed a webcam add-on .

In the code I attached I take a frame from a video, and now I want to take the frames in real time that the webcam is taking

See attached sample code. Adapt as needed to do whatever algorithm you want.

thanks. I need something like that but what can I write instead of Videoreader?

    
    cam = webcam('Microsoft® LifeCam HD-3000');
    preview(cam)
    % videoName = 'tt1.mp4';
    % videoReader = VideoReader(videoName);
    timeStamp = 0.06667;                   % time from the beginning of the video
    videoReader.CurrentTime = timeStamp;   % point to the chosen frame
