import os import subprocess

定义输入输出文件路径

input_path = '' output_path = ''

支持的视频格式

supported_formats = ['.mp4', '.mkv', '.wmv', '.avi', '.rmvb', '.rm', '.flv', '.mov', '.ts', '.m2ts', '.mpeg', '.asf', '.asx', '.vob' , '.m2t', '.3gp']

获取视频列表

def get_video_list(path): video_list = [] if os.path.isfile(path) and os.path.splitext(path)[1] in supported_formats: video_list.append(path) elif os.path.isdir(path): for file_name in os.listdir(path): if os.path.splitext(file_name)[1] in supported_formats: video_list.append(os.path.join(path, file_name)) return video_list

按照最后修改时间排序

def sort_video_list(video_list): video_list.sort(key=lambda x: os.path.getmtime(x), reverse=True) return video_list

剪辑视频

def clip_video(video_path, start_time='00:00:00.000', end_time=None): video_name = os.path.basename(video_path) output_path = os.path.join(os.path.dirname(video_path), 'clip_' + video_name) if not start_time: start_time = '00:00:00.000' if end_time is None: cmd = 'ffmpeg -ss '{}' -i '{}' -c copy '{}''.format(start_time, video_path, output_path) else: cmd = 'ffmpeg -ss '{}' -to '{}' -i '{}' -c copy '{}''.format(start_time, end_time, video_path, output_path) with open(os.devnull, 'w') as devnull: subprocess.Popen(cmd, shell=True, stdout=devnull, stderr=subprocess.PIPE)
