前言

前段时间公司在做流媒体服务,与许多厂家合作拿了许多视频过来,现在要对这些视频文件进行整理,通过特殊的编码排列,获取他们的时长以及分辨率,这里我遇到一个大坑,请往下面看。

# -*- coding: utf-8 -*-
import os
import sys
import shutil
import subprocess
import json
def getLength(filename):
command = ["ffprobe.exe","-loglevel","quiet","-print_format","json","-show_format","-show_streams","-i",filename]
result = subprocess.Popen(command,shell=True,stdout = subprocess.PIPE, stderr = subprocess.STDOUT)
out = result.stdout.read()
#print(str(out))
temp = str(out.decode('utf-8'))
try:
data = json.loads(temp)['streams'][1]['width']
except:
data = json.loads(temp)['streams'][0]['width']
return data def getLenTime(filename):
command = ["ffprobe.exe","-loglevel","quiet","-print_format","json","-show_format","-show_streams","-i",filename]
result = subprocess.Popen(command,shell=True,stdout = subprocess.PIPE, stderr = subprocess.STDOUT)
out = result.stdout.read()
#print(str(out))
temp = str(out.decode('utf-8'))
data = json.loads(temp)["format"]['duration']
return data
