matlab读取视频，不光是avi格式的视频。还包括mp4等格式的视频，读取后视频以多幅帧图像显示-matlab reads the video, not only avi video format. Also includes video format mp4, etc., after reading the video display with multiple frames

将视频转换成一帧一帧的图片,并且支持多种视频格式，如avi MP4 mkv等格式。-convert video into images

该程序为帧间差分算法，可实现MP4格式，AVI格式的视频做差分，差分效果还是比较明显的，自定义帧数差分。-The program for the inter-frame difference algorithm can be realized MP4 format, AVI video format do differential, differential effect is quite obvious, custom frames difference.
