Python 批量修改 MP4 文件语言信息（支持文件夹路径）

import subprocess import os

input_folder = 'path/to/folder/' output_folder = 'path/to/folder/'

for file in os.listdir(input_folder): if file.endswith('.mp4'): input_file = os.path.join(input_folder, file) output_file = os.path.join(output_folder, 'output_' + file) cmd = ['ffmpeg', '-i', input_file, '-empty_hdlr_name', '1', '-metadata:s:v:0', 'language=jpn', '-metadata:s:a:0', 'language=jpn', '-c', 'copy', '-disposition:v:1', 'attached_pic', output_file] subprocess.run(cmd, check=True)
