I have a problem in extracting the video frames.My code does'nt work.Can anyone help me in correcting my mistakes?
vid=VideoReader('Documents\MATLAB\Video\WIN_20181128_00_37_49_Pro.MP4');
numFrames = vid.NumberOfFrames;
n=numFrames;
Folder = 'Documents\MATLAB\Video\';
for iFrame = 1:n
frames = read(vid, iFrame);
imwrite(frames, fullfile(Folder, sprintf('%06d.jpg', iFrame)));
end
FileList = dir(fullfile(Folder, '*.jpg'));
for iFile = 1:length(FileList)
aFile = fullfile(Folder, FileList(iFile).name);
img = imread(aFile);
end

Off the top of my head it looks okay, though your folder will be relative to your current folder, not your root folder. And your final for loop doesn't really do anything except read in files - it doesn't display them or anything.
Perhaps if you described what "doesn't work" means.
I attach a program that does the same thing and I know works. Just change the video filename, output folder name, etc.
