Matlab 视频读写操作


1）：视频读取，

function moive=read_moive(file)

readerobj=VideoReader(file)

NumFrame=readerobj.NumberOfFrames;

for k=1:NumFrame

frame=read(readerobj,k);

moive(k).cdata=frame;

moive(k).colormap=[];

end

end

1）：视频写

function moive=save_moive(moive_data，filename)

writerObj=VideoWriter(tmp_name,'Uncompressed AVI'); %%对应VideoReader()函数

writerObj.FrameRate=10;

open(writerObj); %%%将对象打开

for k=1:length(moive_data);

frame = moive_data(k).cdata;

writeVideo(writerObj,frame);

end

close(writerObj);

end
