python 通过视频url获取视频的宽高方式

这里其实是通过获取视频截图的方式获得大小的

下面列举两个小demo

import cv2 #引入模块 获取视频截图的 from PIL import Image #引入模块 获取图片大小import os #引入系统命令 删除图片video_full_path="http://qnmov.a.yximgs.com/upic/2018/06/06/12/BMjAxODA2MDYxMjQwMTZfMTkzMDUyMjRfNjU2NzMwNzI5MF8xXzM=_hd3_Bc143c8abf799984d2cc75a52de7039f0.mp4?tag=1-1530685096-h-0-xbkiau97pb-2b932528a435f1d0"cap = cv2.VideoCapture(video_full_path)#print(cap.isOpened())if cap.isOpened():#正常打开  rval,frame = cap.read()else:  rval = Falsecv2.imwrite("a.jpg",frame)img = Image.open('a.jpg')print(type(img.size))print(img.size[0])print(type(img.size[0]))my_file = "images/1.jpg"if os.path.exists(my_file):  os.remove(my_file)else:   print("no such file") 

demo2 更新数据库
