How to play movine backward in matlab?

Hi all

I want to play video frames backwardly in matlab can any one help in this regards

My code is

source='LID.AVI';

vidobj=VideoReader(source);

frames=vidobj.NumberofFrames

for f=1:frames

thisframe=read(vidobj,f);

figure(1);imshow(thisframe);

end

This plays the video normally but when I want to change the loop

for f=frame:1

thisframe=read(vidobj,f);

figure(1);imshow(thisframe);

end

it does not work.any help is appreciated

and how can I simultaneously play two frames.I mean backward video as well as forward video

for f1:1:frames
thisframe=read(vidobj,f1);

for f2=frames:-1:1
itframe=read(vidobj,f2);

end

end

for f1 = 1 : frames
  thisframe = read(vidobj, f1);
  otherframe = read(vidobj, frames - f1 + 1);
  %display thisframe at this point
  %display otherframe at this point
end
