Stream the World script not working after all these years

Hey guys. I've been using this script for years to find the URL so that I can use wget to grab streams:

Code:

#!/usr/bin/env python



from random import choice

import os

import sys

import urllib2

import xml.dom.minidom as minidom



def validate_callsign(cs):

        '''

        Normal callsign format is 'WWWWFFAAA', where 'WWWW' is the radio station

        callsign, 'FF' is either 'AM' or 'FM', and 'AAA' is always 'AAC'.

        For this function, we expect the 'WWWWFF' part as input.

        '''

        if not cs or not isinstance(cs, str):

                raise ValueError('callsign \'%s\' is not a string.' % cs)

        if len(cs) < 6:

                raise ValueError('callsign \'%s\' is too short.' % cs)

        if not cs.endswith('AAC'):

                cs = cs + 'AAC'

        band = cs[-5:-3]

        if band != 'AM' and band != 'FM':

                raise ValueError('callsign \'%s\' is missing \'FM\' or \'AM\'.' % cs)

        return cs



def make_request(callsign):

        host = 'playerservices.streamtheworld.com'

        req = urllib2.Request(

                        'http://%s/api/livestream?version=1.2&mount=%s&lang=en' %

                        (host, callsign))

        req.add_header('User-Agent', 'Mozilla/5.0')

        return req



def t(element):

        '''get the text of a DOM element'''

        return element.firstChild.data



def check_status(ele):

        # should only be one status element inside a mountpoint

        status = ele.getElementsByTagName('status')[0]

        if t(status.getElementsByTagName('status-code')[0]) != '200':

                msg = t(status.getElementsByTagName('status-message')[0])

                raise Exception('Error locating stream: ' + msg)



def create_stream_urls(srcfile):

        doc = minidom.parse(srcfile)

        mp = doc.getElementsByTagName('mountpoint')[0]

        check_status(mp)

        mt = t(mp.getElementsByTagName('mount')[0])

        allurls = []

        for s in mp.getElementsByTagName('server'):

                # a thing of beauty, right?

                ip = t(s.getElementsByTagName('ip')[0])

                ports = [t(p) for p in s.getElementsByTagName('port')]

                # yes, it is always HTTP. We see ports 80, 443, and 3690 usually

                urls = ['http://%s:%s/%s' % (ip, p, mt) for p in ports]

                allurls.extend(urls)

        return allurls



def start_mplayer(location):

        print location

        return os.system('mplayer %s' % location)



if __name__ == '__main__':

        if len(sys.argv) < 2:

                print 'usage: station callsign must be the first argument'

                sys.exit(1)



        callsign = validate_callsign(sys.argv[1])



        req = make_request(callsign)

        result = urllib2.urlopen(req)



        urls = create_stream_urls(result)

        if len(urls) > 0:

                u = choice(urls)

                sys.exit(start_mplayer(u))

        sys.exit(1)

This has worked great for MANY years. Suddenly it seems that some stations are changing their URLs on every request. Here's an example with commands issued within a few seconds of each other:

Code:

root@debian# python streamtheworld.py KPELAMAAC            

http://14133.live.streamtheworld.com:3690/KPELAMAAC

( /mnt/data/data/radio/bin )

root@debian# python streamtheworld.py KPELAMAAC

http://13733.live.streamtheworld.com:3690/KPELAMAAC

( /mnt/data/data/radio/bin )

root@debian# python streamtheworld.py KPELAMAAC

http://14213.live.streamtheworld.com:80/KPELAMAAC

Does anyone know of a good way around this or do I need to look at a different stream capture method? Is there something decent for Linux?

Many thanks!
