Hi folks,
This is a followup to my original question, found here!
I am creating a video and having trouble with the videoWriter not closing, or taking a very long time to close.
It appears it doesn't actually get to the close(writeObj) statement as I left the programme running over 2 days and had no video files written.
May I please ask how to fix this? The code is as follows:
writerObj = VideoWriter(mainVideoName);
writerObj.FrameRate = 10;
open(writerObj);
for j = 1 : numMainImages
mainImg = imread([imageMainFolder imageMainFiles(j).name]);
mainImg = mainImg(:,:,1:3);
cropImg = imread([cropsFolder cropFiles(j).name]);
threshImg = im2uint8(imread([threshFolder threshFiles(j).name]));
h = figure;
h(1) = subplot(2, 2, 1);
image(cropImg, "Parent", h(1));
h(2) = subplot(2, 2, 2);
image(threshImg, "Parent", h(2));
h(3) = subplot(2, 2, 3:4);
image(mainImg, "Parent", h(3));
myText = ['Temperature = ', num2str(myTemp(j)), '^{o}C'];
annotation('textbox', [0.4, 0.55, 0,0], 'string', myText, "FitBoxToText","on");
h(2).Colormap = gray(256);
for k = 1:3
h(k).XAxis.Visible = "off";
h(k).YAxis.Visible = 'off';
end
thisFrame = getframe(gca);
writeVideo(writerObj, thisFrame);
end
close(writerObj);

hi @yanqi liu I'm afraid this doesn't work either, as the code never actually makes it to the close(writerObj) line.
