如何使用 python 在 Windows 10 中获取当前正在播放的媒体的标题
问题描述
无论何时在 Windows 10 中播放音频,无论是来自 Spotify、Firefox 还是游戏.当你打开音量时,windows 的角落里会显示歌曲艺术家、标题以及正在播放的应用程序,如下图所示(有时它只显示游戏正在播放声音时哪个应用程序正在播放声音)
Whenever audio is playing in windows 10, whether it is from Spotify, Firefox, or a game. When you turn the volume, windows has a thing in the corner that says the song artist, title, and what app is playing like the photo below (sometimes it only says what app is playing sound if a game is playing the sound)
我想以某种方式使用 python 获取这些数据.我的最终目标是,如果应用程序正在播放我不喜欢的内容(例如广告),则将其静音.
I want to somehow get that data with python. My end goal, is to mute an application if it is playing something I don't like, such as an advertisement.
解决方案
我正在获取windows的标题来获取歌曲信息.通常,应用程序名称显示在标题中,但在播放歌曲时,会显示歌曲名称.这是一个返回所有窗口标题列表的函数.
I am getting the titles of the windows to get the song information. Usually, the application name is displayed in the title, but when it is playing a song, the song name is shown. Here is a function that returns a list of all the window titles.
from __future__ import print_function
import ctypes
def get_titles():
EnumWindows = ctypes.windll.user32.EnumWindows
EnumWindowsProc = ctypes.WINFUNCTYPE(ctypes.c_bool, ctypes.POINTER(ctypes.c_int), ctypes.POINTER(ctypes.c_int))
GetWindowText = ctypes.windll.user32.GetWindowTextW
GetWindowTextLength = ctypes.windll.user32.GetWindowTextLengthW
IsWindowVisible = ctypes.windll.user32.IsWindowVisible
titles = []
def foreach_window(hwnd, lParam):
if IsWindowVisible(hwnd):
length = GetWindowTextLength(hwnd)
buff = ctypes.create_unicode_buffer(length + 1)
GetWindowText(hwnd, buff, length + 1)
titles.append(buff.value)
return True
EnumWindows(EnumWindowsProc(foreach_window), 0)
return titles
