matlab播放视频

可以使用`mmreader`和`read`函数来读取视频帧，然后使用`movie`函数在MATLAB中播放视频。具体代码如下所示：

readerobj = mmreader('video.avi');
vidFrames = read(readerobj);
numFrames = readerobj.NumberOfFrames;
for k = 1:numFrames
    mov(k).cdata = vidFrames(:,:,:,k);
    mov(k).colormap = [];
end
movie(mov);

另外，你也可以使用`VideoReader`和`implay`函数来播放视频：

obj = VideoReader('video.avi');
while hasFrame(obj)
    frame = readFrame(obj);
    imshow(frame);
end

你还可以使用`VideoReader`和`vision.VideoPlayer`来播放视频：

obj = VideoReader('video.avi');
videoPlayer = vision.VideoPlayer;
while hasFrame(obj)
    frame = readFrame(obj);
    videoPlayer(frame);
end
