方法一：VideoFileClip
|
1 2 3 4 5 6 |
from moviepy.editor import VideoFileClip
def get_duration_from_moviepy(url): clip = VideoFileClip(url) return clip.duration |
方法二：CV2
最快。

import cv2
def get_duration_from_cv2(filename): cap = cv2.VideoCapture(filename) if cap.isOpened(): rate = cap.get(5) frame_num =cap.get(7) duration = frame_num/rate return duration return -1 |
方法三：FFmpeg

import ffmpy3
def get_duration_from_ffmpeg(url): tup_resp = ffmpy3.FFprobe( inputs={url: None}, global_options=[ '-v', 'quiet', '-print_format', 'json', '-show_format', '-show_streams' ] ).run(stdout=subprocess.PIPE)
meta = json.loads(tup_resp[0].decode('utf-8')) return meta['format']['duration'] |
