vidObj = VideoReader('xylophone.mp4');
 
gotdata = false;
mip = [];
% Read video frames until not available
while hasFrame(vidObj)
    vidFrame = readFrame(vidObj);
    if ~gotdata
       mip = vidFrame;
       gotdata = true;
    else
       mip = max(mip, vidFrame);
    end
end

clear vidObj

imshow(mip)
