I am trying this code , it work with me for som videos , but for the other one I get all frames: black
Any idea about how I can solve this ?
I try to convert it to avi but I get the same, and I couldn't attach it here because it is too large
vidObj = VideoReader('002.mp4');
s = struct('cdata',zeros(vidObj.Height,vidObj.Width,3,'uint8'),'colormap',[]);
>> vidObj.CurrentTime = 0.6;
>> k = 1;
while vidObj.CurrentTime <= 0.9
s(k).cdata = readFrame(vidObj);
k = k+1;
end
whos s

Can you post a couple of the frames that you get from VideoReader, as a MAT file? Why do you need the 'colormap' stuff and please post the code that you use to display the frames in the structure s.
