python获取视频宽高,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 = False

cv2.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

#!/usr/bin/env python3

#-*- coding:utf-8 -*-

from short_video import ShortVideo

import json

import re

import requests

import hashlib

import cv2

from PIL import Image

import logging

import os

try:

query = ShortVideo().select()

except:

print('操作失败')

else:

for item in query:

shv = ShortVideo().select().where(ShortVideo.video_identify_md5 == item.video_identify_md5).get()

video_url = shv.video_url

cap = cv2.VideoCapture(video_url)

if cap.isOpened():

rval,frame = cap.read()

cv2.imwrite("images/"+str(shv.id)+".jpg",frame)

img = Image.open("images/"+str(shv.id)+".jpg")

w = img.size[0]

h = img.size[1]

shv.width_height = str(w)+'x'+str(h)

#更新完删除文件

my_file = "images/"+str(shv.id)+".jpg"

if os.path.exists(my_file):

os.remove(my_file)

else:

logging.info("no such file")

else:

logging.info('id:'+str(shv.id)+"更新失败")

continue

if shv.save() == 1:

print('更新成功')

else:

print('更新失败')

以上这篇python 通过视频url获取视频的宽高方式就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持python博客。
