将程序视频输入代码改为： %VideoPlay v = VideoReader('xylophone.mp4');%460k; %read some images frame = read(v,1); frame = read(v,Inf); frames = read(v,[1 Inf]); info = mmfileinfo('xylophone.mpg') audio = info.Audio video = info.Video size(frames,1 )*size(frames,2 )*size(frames,3 )size(frames,4 )8/(2^108) %look every images Time=size(frames,4) for i=1:Time imshow(frames(:,:,:,i)); pause(1/(4v.FrameRate)); end并返回完整代码

完整代码如下所示：

% Video input code
v = VideoReader('xylophone.mp4');
frames = read(v,[1 Inf]);
info = mmfileinfo('xylophone.mpg');
audio = info.Audio;
video = info.Video;
size(frames,1)*size(frames,2)*size(frames,3)*size(frames,4)*8/(2^10*8);

% Video playback code
Time = size(frames,4);
for i = 1:Time
    imshow(frames(:,:,:,i));
    pause(1/(4*v.FrameRate));
end

这段代码将视频文件 "xylophone.mp4" 读入并存储在变量 `frames` 中，然后使用 `mmfileinfo` 函数获取视频文件的音频和视频信息。最后，使用 `imshow` 函数和 `pause` 函数循环播放视频。
