我正在尝试创建一个 python 脚本，将音频和视频文件合并到一个（音频+视频）文件中。

我正在使用 ffmpeg 来实现此目的，但它不起作用，并且出现错误。运行此脚本时，这里是我的脚本。

import os
import subprocess
import time
from datetime import datetime
def merge_all():
    
 global p
 p =subprocess.Popen('ffmpeg -i temp_vid.mp4 -i temp_voice.wav -c:v copy -c:a aac -strict experimental - 
 strftime 1 ' + dt_file_name ,stdin=subprocess.PIPE,creationflags = subprocess.CREATE_NO_WINDOW)
  time.sleep(2)
  print('merging done')
  os.remove('temp_vid.mp4')
  os.remove('temp_voice.wav')
  print('file delete done')>

这是错误
