当已经打开时，如何用Python控制VLC

Question

我有一个代码，可以成功打开VLC，全屏幕，添加媒体等，所有这些都一行 - 例如（摘自较长的代码）：

p = subprocess.Popen(["C:/Program Files (x86)/VideoLAN/VLC/vlc.exe","--one-instance","--fullscreen","--playlist-enqueue",clips[selection],speed[speed_selection]])

该特定行在循环内。我想打开循环的vlc ，然后添加媒体，然后在中选择速度，如（摘录）：

p = subprocess.Popen(["C:/Program Files (x86)/VideoLAN/VLC/vlc.exe","--fullscreen"])
timer = 0
while timer <= 19:
        selection = randint(1, 11)
        speed_selection = randint(1, 4)
        p = subprocess.Popen(#???? is this even the right command?)([#Something here to refer to vlc??,"--playlist-enqueue",clips[selection],speed[speed_selection]])
        timer += 1

我似乎找不到或找出与已经打开的VLC播放器通信的语法。我会收到错误'FilenotFoundError：[WinError 2]系统无法找到指定的文件'每次尝试任何事情时，这是有道理的，因为我没有正确地告诉Popen在哪里打开这些东西！

可能是p = subprocess.popen（）是不正确的语法，或者在括号内我需要以某种方式参考VLC而不打开其他实例？

任何提出的建议。

speed = {1: "--rate=1.0", 2: "--rate=1.5", 3: "--rate=2.0", 4: "--rate=0.5"}
import subprocess
from random import randint
p = subprocess.Popen(["C:/Program Files (x86)/VideoLAN/VLC/vlc.exe","--fullscreen"])
timer = 0
while timer <= 19:
        selection = randint(1, 11)
        speed_selection = randint(1, 4)
        p = subprocess.Popen(["--playlist-enqueue",clips[selection],speed[speed_selection]])
        timer += 1

我做了一个python模块来解决此问题。televlc

    ~$ pip install televlc

创建VLC实例和接口，然后连接

    import televlc
    # Initialize the vlc object
    vlc = televlc.VLC()
    # Open a VLC instance and create the telnet interface
    vlc.start_telnet_interface()
    # Connect to the telnet interface
    vlc.connect_to_telnet_interface()
    # Run a command (volume up)
    vlc.do(["volup", "50"])
    # Disconnect from telnet interfac
    vlc.disconnect_from_telnet_interface()
    # or
    vlc.do(["exit"])
    # or end VLC instance and telnet interface
    vlc.do(["shutdown"])

连接到现有VLC实例和接口

这是创建现有实例并在脚本之外连接的命令

    ~$ vlc --extraintf --telnet --telnet-password myPassword --telnet-host myHost --telnet-port myPort

    import televlc
    # Set the interface data
    PASSWORD = myPassword
    HOST = myHost
    PORT = myPort
    # Initialize the vlc object
    vlc = televlc.VLC(PASSWORD, HOST, PORT)
    # Run a command
    command = ["volup", "50"]
    vlc.do(command)
    # Quit
    vlc.disconnect_from_telnet_interface()
