杀死在python subprocess.Popen中打开并由subprocess.kill杀死的进程后，进程statuse为sombi

Question

我正在将python与subprocess.Popen（）配合使用，以输入实时广播流URL来启动FFmpeg，并每30秒制作一次wav文件。 当我尝试使用subprocess.kill（）杀死进程时，它可以工作，但是该进程仍写在/ proc /中，并且如果我签入系统监视器，进程的状态为“ Zombi”。

直到python脚本完成，所以该过程已从/ proc中删除，并且在系统监视器中看不到它。

如何在不关闭python脚本的情况下终止进程？

这是示例

#! /usr/bin/python3 
import os
import subprocess
import time

# Start ffmpeg in background.
folder_name = "path_to_file"
input_ = "https://kanlivep2event-i.akamaihd.net/hls/live/749629/749629/kanmoreshet_mp3/chunklist.m3u8"
ffmpeg_cmd = [
        "ffmpeg",
        "-y",
        "-loglevel", "8",
        "-thread_queue_size", "1500",
        "-i", input_,
        "-c", "copy",
        "-vn",
        "-f", "segment",
        "-segment_time", "30",
        "-ar", "8000",
        "-acodec", "pcm_s32le",
        "-ac", "1",
        "-strftime", "1",
        str(folder_name + '/' + input_.replace("/","") + '_*_*_%s.wav')
    ]
process = subprocess.Popen(ffmpeg_cmd)
# Check if the process is exist
def check_exist(process):
    print("pid - ", process.pid)
    if os.path.isdir("/proc/{}".format(process.pid)):
        print ("Yes")
    else:
        print("No")

check_exist(process)
process.kill()
time.sleep(20)
check_exist(process)
