Hi,
I am trying to log acquired data to disk, and save the video file as mp4 or .avi, but it doesn't create any file in the folder? Any advice would be appreciated.
thanks.
clear ;
close all;
vid = videoinput('winvideo', 1, 'YUY2_640x480');
vid.Timeout = 20;
set(vid, 'FrameGrabInterval', 2);
vid.LoggingMode = 'disk';
logfile = VideoWriter('MATLAB.mp4', 'MPEG-4')
vid.FramesPerTrigger = 20;
start( vid );
wait( vid, Inf );
[d t] = getdata( vid, vid.FramesAvailable );
fps = 1 / mean( diff( t ) );
vid.ReturnedColorSpace = 'grayscale'
preview(vid);
start(vid);
pause(2);
frames = getdata(vid);
stop(vid)
clear vid

Hi,
Probably, you'd need to indicate the directory of your log data as a whole, e.g.: '../dir/videos/MATLAB.mp4'
