Hi,
I understand that you are trying to extract frames from a video at 10 seconds, 20 seconds, 30 seconds, 40 seconds, 50 seconds. Following is the code to perform the operation : -
v = VideoReader('exampleVideo.mp4');
time = [10, 20, 30, 40, 50];
for i=1:numel(time)
if time(i)<v.Duration
v.CurrentTime = time(i);
frame = readFrame(v);
figure; imshow(frame); %Perform processing on the frame here
end
end
For more information, refer to VideoReader.
