how to process multiple video files from a folder
显示 更早的评论
I am in the process of processing numerous video files from a folder, so I need a sample support for processing one video file at a time. I am using the following snippet, but I am getting stuck with the following additional parameter when I look at the file name, which is halting my progress. Any assistance would be greatly appreciated.
folder = 'C:\Video_file\';
files = dir(folder)
files.name
numel(files.name)
ans =
162 % on my windows system
I see followig output
files.name
ans =
'.' % this is NOT required
ans =
'..' % this is NOT required
ans =
'dummy1.avi'
ans =
'dummy2.avi'
Thank you very much.

By far the simplest approach is to specify the filename (using wildcards as required) and fileextension:
F = 'C:\Video_file\';
S = dir(fullfile(F,'*.avi'))

numel(S.name) % this will throw an error if S has zero/multiple elements.
"I want to loop through the files one by one"
You can simply loop over the elements of S:
S = dir(..);
for k = 1:numel(S)
F = fullfile(S(k).folder,S(k).name);
% do whatever you want with filename F
end
