如何找到媒体音量控制覆盖中图像的位置？

我偶然发现了这里的答案

这是文档

以下是如何在 python 中将图像保存到当前目录

import asyncio
from winrt.windows.media.control import \
    GlobalSystemMediaTransportControlsSessionManager as MediaManager
from winrt.windows.storage.streams import \
    DataReader, Buffer, InputStreamOptions

async def get_media_info():
    sessions = await MediaManager.request_async()

    # This source_app_user_model_id check and if statement is optional
    # Use it if you want to only get a certain player/program's media
    # (e.g. only chrome.exe's media not any other program's).

    current_session = sessions.get_current_session()
    if current_session:  # there needs to be a media session running
        info = await current_session.try_get_media_properties_async()

        # song_attr[0] != '_' ignores system attributes
        info_dict = {song_attr: info.__getattribute__(song_attr) for song_attr in dir(info) if song_attr[0] != '_'}

        # converts winrt vector to list
        info_dict['genres'] = list(info_dict['genres'])

        return info_dict

    # It could be possible to select a program from a list of current
    # available ones. I just haven't implemented this here for my use case.
    # See references for more information.
    raise Exception('No current media session')

current_media_info = asyncio.run(get_media_info())

async def read_stream_into_buffer(stream_ref, buffer):
    readable_stream = await stream_ref.open_read_async()
    readable_stream.read_async(buffer, buffer.capacity, InputStreamOptions.READ_AHEAD)

# create the current_media_info dict with the earlier code first
thumb_stream_ref = current_media_info['thumbnail']

# 5MB (5 million byte) buffer - thumbnail unlikely to be larger
thumb_read_buffer = Buffer(5000000)

# copies data from data stream reference into buffer created above
asyncio.run(read_stream_into_buffer(thumb_stream_ref, thumb_read_buffer))

# reads data (as bytes) from buffer
buffer_reader = DataReader.from_buffer(thumb_read_buffer)
byte_buffer = buffer_reader.read_bytes(thumb_read_buffer.length)

with open('media_thumb.jpg', 'wb+') as fobj:
    fobj.write(bytearray(byte_buffer))
