Hi,
I understand that you are trying to create a video from images that are coming in the loop. There are multiple issues related to usage to video writer and so on.
Majorly, whenever a call is made to writeVideo, it is expecting an image frame. However, you are passing h, which is a handle to a pcolor object. Hence, you are getting the error: IMG must be of one of the following classes: double, single, uint8.
The way you can solve it is, draw pcolor on an axes and then get the image from that axes for each frame. Once, you get that image, write it to the video.
Here is a full working example,
x1 = randi([0, 5], [4,4]);
x2 = randi([0, 5], [4,4]);
x3 = randi([0, 5], [4,4]);
A(:,:,1)=x1;
A(:,:,2)=x2;
A(:,:,3)=x3;
f = figure;
ax = axes(f);
Q = size(A,3);
W = A(:,:,1);
h = pcolor(ax,W);
drawnow();
pause(0.3);
video = VideoWriter('newfile.avi');
video.FrameRate = 10;
open(video);
for K = 2 : Q
W = A(:,:,K);
set(h, 'CData', W);
drawnow();
img = getframe(f);
writeVideo(video, img);
end
close(video);
Regarding the error resiliente@resiliente-S2600STB:, does not exist.
On a linux machine, the prompt is something like this: "username@machine: path"
You only need to pick up the path from it. The path would be something like /home/..
