out of memory

clear all
mov = aviread('book.avi');
xy=zeros([size(mov(1).cdata),length(mov)], 'uint8');

for ii=1:537
    figure(10)
    ii
    xy(:,:,:,ii)=mov(ii).cdata;
   imshow(xy(:,:,:,ii));
endwhen I read the code,these message also show again.
pleas teach me how to do 
thank!

I did warn you in your previous thread on this topic to expect to run out of memory. No matter how much memory you have, there will be a movie bigger than that.

Are you certain that you need to store the data as a 4D array, and cannot process it in the mov struct instead?

Anyhow:

numframe = 537;
ii = 1;
thisframe = aviread('book.avi', ii);
xy = repmat(thisframe.cdata, [1, 1, 1, numframe]);
figure(10);
ii
imshow(thisframe.cdata);
drawnow();
for ii = 2 : numframe
  thisframe = aviread('book.avi', ii);
  xy(:,:,:,ii) = thisframe.cdata;
  ii
  imshow(thisframe.cdata);
  drawnow();
end

Please expect this to be notably slower than your previous code. As usual, fast operations depend upon having a lot of memory, which you do not have.

Thank for your proposition!!

[Sean de Wolski]

you're trying to create an array the size of

[size(mov(1).cdata),length(mov)]

i.e.

prod([size(mov(1).cdata),length(mov)])

many elements.

How much RAM do you have? Are you on a 64bit system (capable of having more than 3gb of memory)?

32 bit system

Then you limit is somewhere around 3Gb.
