Unable to resolve the name vision.VideoFileReader

This is the code I am trying to execute and I am ending up with the error message that it is "Unable to resolve the name vision.VideoFileReader"

Not getting what exactly is the issue. I have ensured the video file is selected from the right path but still not getting it. Kindly help

%% Set up video reader and player
vision.VideoFileReader('video2.avi')
videoFReader = vision.VideoFileReader('video2.avi',...
    'VideoOutputDataType','double');
vidPlayer = vision.VideoPlayer;

Hi,

In order use vision.VideoFileReader you need to install computer vision toolbox.

Make sure you have installed computer vision toolbox at your end by using "ver" command in your MATLAB command prompt.

If computer vision toolbox is not installed you can download from the below link

I have the same trouble as you. How did you figure it out in the end?

Yes, he said that he did not have the Computer Vision Toolbox and he installed that, and then it worked. If you don't have that (type "ver" to find out) then contact Mathworks sales.

However you can use VideoReader() and VideoWriter(), without the "vision." prefix, since those functions are built in to base MATLAB.
