A=VideoReader('rhinos.avi');B=read(A);
disp(size(B))
N_Frames=A.NumFrames
Height=A.Height
Width=A.Width
mov(1:N_Frames)=struct('cdata',zeros(Height,Width,3,'unit8'),'colormap',[]);
for i=1:N_Frames
mov(i).data=B(:,:,:,i)
end
h=figure
set(h,'position',[150,150,Width,Height]);
movie(h,mov);
这个视频文件是matlab自带的文件,为什么出错了呢,应该怎么改呢?
