I'm trying to load a video file in directory to capture frames and i keep getting the error this error. Below is the code and the error that I am getting
obj = VideoReader(Climate.mp4);
for k = 1 : 5 %fill in the appropriate number
this_frame = READFRAME(obj, k);
thisfig = figure();
thisax = axes('Parent', thisfig);
image(this_frame, 'Parent', thisax);
title(thisax, sprintf('Frame #%d', k));
end
Undefined variable "Climate" or function "Climate.mp4".
Error in Climate_Change (line 48)
obj = VideoReader(Climate.mp4);
How do I fix this?
Thank you

You might happen to be using an old version between the time that VideoReader was introduced but before the readFrame() method was introduced (note capitalization, by the way.) If so then you will need to recode in terms of the older read() method; https://www.mathworks.com/help/matlab/ref/videoreader.read.html
