hdhr-listings-to-m3u.py

#
# this script will convert the hdhomerun listings (channels) to
# m3u format for use with external media players. before running
# this script, be sure to modify the <<config>> variable settings
# below.
#
# Suggested Usage: This script should be run on a cron to keep
# the channel lineup to date. Below is an example of how to execute this script:
# python /path/to/script/hdhomerun-prime-listings-to-m3u.py > /path/to/playlist.m3u

import requests
import json
from pprint import pprint

# * hdhr-ip: ip address of your hdhr prime unit
# * duration: the duration the stream should play for. some
# players seem to require this while others do not. default
# is set for 7200 minutes (2 hours)
config = {
    'hdhr-ip'   : '192.168.1.100',
    'duration'  : '7200',
}

hdhr_url        = "http://{0}/lineup.json?show=unprotected".format(config['hdhr-ip'])
response_obj    = requests.get(hdhr_url)
listings_res    = response_obj.text

print "#EXTM3U"
listings = json.loads(listings_res)
for l in listings:
    channel = l['GuideNumber']
    name    = l['GuideName']

    #print "#EXTINF:{0},{1}: {2}".format(channel,channel, name)
    print '#EXTINF:-1 tvg-name="{1}" tvh-chnum="{0}",{1}'.format(channel, name)
    print "http://{0}:5004/auto/v{1}?duration={2}".format(
            config['hdhr-ip'],
            channel,
            config['duration']
    )

Just a heads up, I ported this over to Python 3 and added dynamic IP address finding here: https://gist.github.com/caseyavila/f37abe5490d4abfc83a75e65056bda6c
