检查是否在Windows 10上使用Python播放音频

问题描述：

我正在Windows 10上使用Python 3.7.我想检测计算机上是否有音频播放.我一直在寻找 win32api.GetVolumeinformation ，但无法获得想要的东西.

I'm working with Python 3.7 on Windows 10. I would like to detect if there is any audio playing on my computer or not. I was looking into win32api.GetVolumeinformation but I'm unable to get what I want.

控制音频时，您可以查看是否正在播放一个程序，我想实现这一目标.

When you control your audio you can see if there is a program playing and I want to achieve that.

答

使用winrt尝试以下api:枚举选项在此处列出，但您可以使用 mediaIs("PAUSED")， mediaIs("PLAYING")等...

Try this api using winrt: The enum options are listed here, but you can use mediaIs("PAUSED"), mediaIs("PLAYING") ect...

import asyncio, winrt.windows.media.control as wmc

def mediaIs(state):
    session = asyncio.run(getMediaSession())
    if session == None:
        return False
    return int(wmc.GlobalSystemMediaTransportControlsSessionPlaybackStatus[state]) == session.get_playback_info().playback_status #get media state enum and compare to current main media session state

也有很多更有用的winrt API来控制Windows上的媒体

There are heaps more useful winrt APIs to control media on windows too here.
