Record streaming and saving internet radio in python

Question

I am looking for a python snippet to read an internet radio stream(.asx, .pls etc) and save it to a file.

The final project is cron'ed script that will record an hour or two of internet radio and then transfer it to my phone for playback during my commute. (3g is kind of spotty along my commute)

any snippits or pointers are welcome.

Answer 1

I am aware this is a year old, but this is still a viable question, which I have recently been fiddling with.

Most internet radio stations will give you an option of type of download, I choose the MP3 version, then read the info from a raw socket and write it to a file. The trick is figuring out how fast your download is compared to playing the song so you can create a balance on the read/write size. This would be in your buffer def.

Now that you have the file, it is fine to simply leave it on your drive (record), but most players will delete from file the already played chunk and clear the file out off the drive and ram when streaming is stopped.

I have used some code snippets from a file archive without compression app to handle a lot of the file file handling, playing, buffering magic. It's very similar in how the process flows. If you write up some sudo-code (which I highly recommend) you can see the similarities.

Answer 2

The following has worked for me using the requests library to handle the http request.

import requests

stream_url = 'http://your-stream-source.com/stream'

r = requests.get(stream_url, stream=True)

with open('stream.mp3', 'wb') as f:
    try:
        for block in r.iter_content(1024):
            f.write(block)
    except KeyboardInterrupt:
        pass

That will save a stream to the stream.mp3 file until you interrupt it with ctrl+C.
