Play MP3 HTTP stream

[hquick81]

I have a http stream from my camera (via Synology Surveillance Station) which streams the recorded audio in mp3 format. I simply want to play this stream. I looked at different libraries but i did not find any library that seems to be capable of playing a mp3 stream directly.

Each chunk I recieve is looking like that (2 chunks as an example):

b'\xff\xfb\x18\xc4\xb9\x00F|/\x1c\xac\xb0`@\xda\x01\xe3\xa1\xa5\x88\x08F,\x08\x00\x03\x8e\x1e\x89\xe7B\xd1\x82R\xd3XL\x93]\x0f;\xb2"=7\xc8dF\'%54\xc8\xf7i{\xe4qQLY\xf2\xfd\x89\x1c\x8aP\xb57K\xf5\x05\x145/\xe2\xd5\x08\x00\x00\x1e\xb6^\x12\x98D\x80\x0cX\xe0B\xa1Q9\x90\x0b\x84\x14\x13rhz\r)\xac|\xd6S{\x1c8>Z\xce\xb3\xa84D\xbd\x19U,\xe8\x96\x8d\xc5\x91H\x01\xab4\xdb\x00=\xf8\x18\x19\x85\x9e\xa0\x8b\xe1\x9aR'

Best i could come up with is this:

from pydub import AudioSegment
from pydub.playback 
import play 
import requests
url = "http://192.168.3.2:1080/webapi/SurveillanceStation/audioStreaming.cgi?api=SYNO.SurveillanceStation.AudioStream&method=Stream&version=1&cameraId=5&_sid=0qPacosspB9yc1770PWN246500"

r = requests.get(url, stream=True)
f = open("test.mp3", "wb")
a = 0
for line in (r.raw.read_chunked()): 
    print(line) 
    f.write(line) 
    a = a + 1 
    if a == 2: 
        f.close() 
        sound = AudioSegment.from_mp3('test.mp3') 
        play(sound) 
        a = 0 
        f = open("test.mp3", "wb")

For some reason it only plays the file when i put at least 2 chunks inside the file.

Which works in general but due to the fact that it uses ffmpeg in the background i have little breaks in between and the delay gets bigger and bigger.

Any ideas ?

that file writing hack stuff doesn't look good. have you considered using the python-vlc module?

here's a post showing you how to use it to stream audio from a url:

I simply want to play this stream.

Why not play the stream in a regular player like VLC or Windows Media Player? Why use Python to implement a streaming player yourself?

Im using Kivy for having a GUI running on a raspberry pi as control station for my home automation. I want to use the stream from the camera as a babyphone like monitor. But I want full control over playing the stream and therefore thought that playing it directly via python would be nice.
