Matlab-Video2Frame并保存到指定文件夹

fileName = 'C:\Users\Wu\Desktop\SumMe\videos\Base jumping.mp4';

str = 'C:\Users\Wu\Desktop\SumMe\video_to_jpg\Base jumping\';

obj = VideoReader(fileName);

numFrames = obj.NumberOfFrames;% 帧的总数

for k = 1 : numFrames% 读取数据

frame = read(obj,k);

%imshow(frame);%显示帧

imwrite(frame,strcat(str,num2str(k),'.jpg'),'jpg');% 保存帧
