现在我有这些库:请求, pyglet , pyaudio
如何播放音频流,例如,从this网站播放音频流而不将其保存到文件中(使用缓冲)?
关于StreamingSource类
,此库的文档中存在令人困惑的信息当我在StreamingSource对象(source.get_audio_data(DATA))中按字节推送信息时,我将其推入播放器(pyglet.media.Player())后会抛出一个异常,表示StreamingSource没有属性持续时间
代码:
import pyglet, requests
req = requests.get('http://ic7.101.ru:8000/c15_3', stream=True)
player = pyglet.media.Player()
source = pyglet.media.StreamingSource()
CHUNK = 1024
for num, chunk in enumerate(req.iter_content(CHUNK)):
if num == 1000:
break
source.get_audio_data(chunk)
if num == 100:
player.queue(source)
player.play()
pyglet.app.run()
pyglet.clock.schedule_once(lambda dt: pyglet.app.exit(), source.duration)
回溯:
Traceback (most recent call last):
File "/home/user/.PyCharmCE2017.1/config/scratches/scratch.py", line 16, in <module>

self.duration += source.duration

如果您只想从网址播放文件(音频/视频)而不保存,可以使用vlc
,如下所示。
vlc
的详细信息为here
您可以安装vlc
(在Windows上)
pip install python-vlc
源代码
import vlc
url = 'http://ic7.101.ru:8000/c15_3'
#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()
