out of Memory ,when reading a video of 22 seconds

Hi..Im extracting frames from a video. Previously I extracted frames from a 5 seconds video clip and when Im trying to extract from a 22 seconds video clip using * aviread* it is showing error as *out of memory *.

How to solve this problem?

Well, do the data of 22 sec match into the available RAM? Is it really necessary to keep all these frames at the same time in the memory?

only one frame is saved at a time using a loop as shown below

folder = fullfile('D:\videofiles\framesNEW');

movieFullFileName = fullfile(folder, 'video.avi');

movieInfo = aviinfo(movieFullFileName);

mov = aviread(movieFullFileName);

numberOfFrames = size(mov, 2);

[folder, baseFileName, extentions] = fileparts(movieFullFileName);

folder = pwd;

outputFolder = sprintf('%s/Frames%s', folder, baseFileName);

mkdir(outputFolder);

for frame =1:numberOfFrames

here I'm extracting each frame and saving it

end;

Use the VideoReader class and the read() function to pull out just one frame at a time rather than a call to aviread() to suck up the whole thing at once, which you apparently cannot do due to memory limitations. I'm not sure what version VideoReader was introduced in but I have it in R2011a.

Same probelm is existing even Im using mmreader also.Im having R2008a.
