1.使用subprocess和re

import re import subprocess video = r"work/train/video/a8b96f016a28d8f3836f7cbb7734ecde.mp4" import subprocessdef get_length(filename):result = subprocess.run(["ffprobe", "-v", "error", "-show_entries","format=duration", "-of","default=noprint_wrappers=1:nokey=1", filename],stdout=subprocess.PIPE,stderr=subprocess.STDOUT)return float(result.stdout) t=get_length(video) print(t)

2.使用VideoFileClip

from moviepy.editor import VideoFileClip clip=VideoFileClip(video) print(clip.duration)

使用cv2

import cv2 def get_video_duration(filename):cap = cv2.VideoCapture(filename)if cap.isOpened():rate = cap.get(5)frame_num =cap.get(7)duration = frame_num/ratereturn durationreturn -1 t=get_video_duration(video) print(t)

從結果可以看出，cv2的運行時長是最短的，推薦使用cv2
