import os import subprocess

folder_path = '/path/to/folder' # 替换为你要扫描的文件夹路径 output_folder = '/path/to/output' # 替换为你要输出的文件夹路径

for filename in os.listdir(folder_path): if filename.endswith('.mp4'): input_file = os.path.join(folder_path, filename) output_file = os.path.join(output_folder, 'output_' + filename) 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)
