如何在 Python 3.5.3 上播放来自网络电台的流音频

How to play streaming audio from internet radio on Python 3.5.3(如何在 Python 3.5.3 上播放来自网络电台的流音频)

问题描述

我在 Windows 8.1 x64 上使用 Python 3.5.3，我需要播放来自这里的音频

我尝试过 pyaudio，但它只给我白噪声，并且在运行几次 pyaudio 后出现错误(pyaudio 模块pyaudio"没有属性PyAudio").

请告诉我如何更好地使用 Python 从 url 播放流音频...

附言我已经使用此代码获得了歌曲名称和艺术家姓名:

导入请求导入时间导入日期时间打印(日期时间.日期时间.现在())进口重新url = 'http://prem1.rockradio.com:80/bluesrock?9555ae7caa92404c73cade1d'编码 = 'latin1'信息 = ''radio_session = requests.Session()而真:radio = radio_session.get(url, headers={'Icy-MetaData': '1'}, stream=True)metaint = int(radio.headers['icy-metaint'])流 = radio.rawaudio_data = stream.read(metaint)meta_byte = stream.read(1)如果(元字节):meta_length = ord(meta_byte) * 16meta_data = stream.read(meta_length).rstrip(b'')stream_title = re.search(br"StreamTitle="KFte"]*)';", meta_data)如果流标题:stream_title = stream_title.group(1).decode(encoding, errors='replace')如果信息 != stream_title:打印('正在播放:'，stream_title)信息 = 流标题别的:经过别的:打印('没有流标题！')时间.sleep(1)
 解决方案 
如果你对外部库开放，你可以使用 pip install python-vlc
 为 python 安装 vlc 绑定
并使用 player 方法直接从 URL 播放音频文件，如下所示.
导入vlc导入时间url = 'http://prem1.rockradio.com:80/bluesrock?9555ae7caa92404c73cade1d'#define VLC 实例instance = vlc.Instance('--input-repeat=-1', '--fullscreen')#定义VLC播放器播放器=instance.media_player_new()#定义VLC媒体媒体=instance.media_new(网址)#设置播放器媒体player.set_media(媒体)#播放媒体播放器播放()
vlc 播放器的优点是您可以直接从 URL 播放大多数媒体类型(不仅仅是 mp3)，还可以执行类似播放器的选项，例如
<预><代码>>>>player.pause() #暂停播放>>>player.play() #继续播放>>>player.stop() #停止播放

I am using Python 3.5.3 on Windows 8.1 x64 and i need play audio from here

I have tried pyaudio, but it gives me only white noise and error occurred after a few runs of pyaudio (pyaudio module 'pyaudio' has no attribute 'PyAudio').

Please, advise me how better play the streaming audio from url, using Python...

P.S. I already got the song title and artist name with this code:

import requests
import time
import datetime
print(datetime.datetime.now())
import re


url = 'http://prem1.rockradio.com:80/bluesrock?9555ae7caa92404c73cade1d'
encoding = 'latin1'
info = ''

radio_session = requests.Session()

while True:

    radio = radio_session.get(url, headers={'Icy-MetaData': '1'}, stream=True)

    metaint = int(radio.headers['icy-metaint'])

    stream = radio.raw

    audio_data = stream.read(metaint)
    meta_byte = stream.read(1)

    if (meta_byte):
        meta_length = ord(meta_byte) * 16

        meta_data = stream.read(meta_length).rstrip(b'')

        stream_title = re.search(br"StreamTitle="KFte"]*)';", meta_data)


        if stream_title:

            stream_title = stream_title.group(1).decode(encoding, errors='replace')

            if info != stream_title:
                print('Now playing: ', stream_title)
                info = stream_title
            else:
                pass

        else:
            print('No StreamTitle!')

    time.sleep(1)

If you are open for external libraries, you can install vlc binding for python using pip install python-vlc

And use player method to play audio file directly from URL as below.

import vlc
import time

url = 'http://prem1.rockradio.com:80/bluesrock?9555ae7caa92404c73cade1d'

#define VLC instance
instance = vlc.Instance('--input-repeat=-1', '--fullscreen')

#Define VLC player
player=instance.media_player_new()

#Define VLC media
media=instance.media_new(url)

#Set player media
player.set_media(media)

#Play the media
player.play()

Advantage of vlc player is that you can play most media types directly from URL (not just mp3) and also perform player like options such as

>>> player.pause()  #pause play back
>>> player.play() #resume play back
>>> player.stop() #stop play back
