My matlab code is this
video = VideoReader('video1.avi'); for i = 1:video.NumberOfFrames img = read(video,i); imwrite(img,sprintf('img%d.jpg',i)); end
fprintf('Please wait....');
filebase = dir('*.jpg');
num_files = nume1(filebase);
images = cell(1, num_files);
MS=cell(1,num_files);
for k = 1:num_files
images{k} = imread(filebase(k).name);
[rows columns color]=size(images{1});
if (color==3)
MS{k}=image_enhancement_sw(images{k});
M(k)=im2frame(MS{k});
else
MS{k}=gray_level_images(images{k});
end
end
movie(M)
but i cant able to execute the code
im getting the following error
can anyone please help me with dis.....
??? The file requires the following codec(s) to be installed on your system: h264
Error in ==> VideoReader.VideoReader>VideoReader.init at 423 obj.VideoReaderImpl = audiovideo.mmreader(fullName);
Error in ==> VideoReader.VideoReader>VideoReader.VideoReader at 133 obj.init(fileName);
Error in ==> eg at 1 video = VideoReader('video1.avi');

I do this in second half of my demo. Follow what I did in the attached m-file.

in this vidFrames hold and store your all frames. You can use a Frame by using mov(i).data
readerobj = mmreader('dd.avi');
vidFrames = read(readerobj);
numFrames = get(readerobj, 'numberOfFrames');
For i=1:numFrames-1
mov(i).data=vidFrames(:,:,:,i).
end
