iheartradio – command line (mplayer)

Well after some experimentation and playing around I have found some new information out regarding listening to iheartradio from the command line in Linux.

Newer versions of mplayer have support to play the rtmp:// protocol eliminating the need for rtmpdump.

Quick Recap on how to grab the rtmp:// url from an iheartradio stream

  • Go to http://p2.STATION_ID.ccomrcdn.com/player/player_dispatcher.html?section=radio&action=listen_live; where station id is the call letters (ex: wtfx-fm)
  • The attribute primary_location in <stream> contains the rtmp url

NOTE: The RTMP URL changes every 5-10 minutes! You must fetch the new url everytime.

To play the stream with mplayer:

mplayer "rtmp://cp21366.live.edgefcs.net/live/Lou_KY_WTFX-FM_OR..." -novideo

The -novideo option is very improtant otherwise mplayer will take 5+ minutes trying to find video for the stream (there is none).

This is all great, but this is a lot of work everytime you want to listen to a iheartradio stream. Therefore I have coded up a script.

The Script:

  • Asks you for the station id (ex: wtfx-fm)
  • Asks how long the stream should play for
  • Check for song information every 10 seconds
  • Not Perfect (Alpha Quality)
#!/usr/bin/env python

import subprocess
import time
import urllib2
import xml.etree.ElementTree as ET
import os
import datetime

#Location of Stream to be SAVED
DefaultStation="wtfx-fm"

def getXML():
    data=urllib2.urlopen('http://p2.'+station+'.ccomrcdn.com/player/player_dispatcher.html?section=radio&action=listen_live').read()
    xml=ET.fromstring(data)
    return xml

def getSongInfo():
    xml=getXML()
    artist=xml.find('ListenLiveInitialize/JustPlayed/song/artist').attrib['name']
    title=xml.find('ListenLiveInitialize/JustPlayed/song/track').attrib['track_title']
    return artist,title



while True:
    station=raw_input("Enter Station ID [" + DefaultStation + "]: ")

    if not station:
        station=DefaultStation
    try:
        xml=getXML()
    except urllib2.URLError:
        print "Error - Invalid Station ID or Web Server Problem - Try Again"
    else:
        break

while True:
    try:
        TIME=int(raw_input("Time Stream will Play (in minutes): "))
    except ValueError:
        print "Error - Invalid Time - Try Again"
    else:
        break

rtmpurl=xml.find("ListenLiveInitialize/StreamInfo/stream").attrib['primary_location']

mp=subprocess.Popen(['/usr/bin/mplayer', rtmpurl, '-novideo', '-ao', 'alsa', '-quiet'], stdout=subprocess.PIPE, stdin=subprocess.PIPE, stderr=subprocess.PIPE)
mpPID=mp.pid

endTime = datetime.datetime.now() + datetime.timedelta(minutes=TIME)

OldSongInfo=[]

while datetime.datetime.now() < endTime:
    SongInfo=getSongInfo()
    if not SongInfo == OldSongInfo:
        OldSongInfo = SongInfo
        print SongInfo[0] + " - " + SongInfo[1]
    time.sleep(5)



print("Stopping MPlayer...")
os.kill(mpPID, 2)

print "Done"

N900

I got this script working on the N900 by downloading the Maemo 5 SDK and compiling the mplayer binary from a recent svn snapshot. Luckily, I didn't run into any problems. Although mplayer works with the N900, without any patches, it is not flawless. For example, video  gets jittery and skips when the backlight switches off. I would recommend leaving mplayer form extra installed and storing the mplayer you compiled in /opt. With audio playback I  do not have any issues, especially with the iheartradio rtmp stream!

Listen to iheartradio without Flash

UPDATE:  http://pyther.net/blog/index.php/2010/08/iheartradio-command-line-mplayer/

If you have ever listened to any Clear Channel FM radio station then I am sure you have heard the ads to listen to the station online through iheartradio. The only problem is that iheartradio is a bulky and slow flash application. On a powerful desktop that isn’t a huge issue, but with my N900 (600mhz cpu, 256MB Ram) it takes over 5 minutes to start streaming the radio station. Of course, iheartradio has an application for the iPod and Blackberry, but no app for the N900.

I went on a quest to figure out how to listen to iheartradio without the bulky flash application and this is what I found.

Step 1:

The url of the a stations stream is can be found in a XML file, at URL “http://p2.STATION_NAME.ccomrcdn.com/player/player_dispatcher.html?section=radio&action=listen_live”

If I want to listen to The Fox (call letters: WTFX-FM), the URL of the XML would be “http://p2.wtfx-fm.ccomrcdn.com/player/player_dispatcher.html?section=radio&action=listen_live”

Open up the url in a web browser and grab the rtmp url which is between the <stream> tags. rtmp://cp21366.live.edgefcs.net/live/Lou_KY_WTFX-FM_OR@s7696?auth=daEcEbgdNb4a3bdcKdYcrcgcGara0c1c3cZ-bmC7wi-4q-LM3Y9_7nqEDps4CCulBtyp&aifp=1234&CHANNELID=981&CPROG=_&MARKET=LOUISVILLE-KY&REQUESTOR=WTFX-FM&SERVER_NAME=p2.wtfx-fm.ccomrcdn.com&SITE_ID=2038&STATION_ID=WTFX-FM&MNM=2&TYPEOFPLAY=0

Step 2:

Download and Install rtmpdump and mplayer

  • Use your distro’s repositories
  • rtmpdump is in AUR (archlinux)

Step 3:

Lastly open up the terminal and enter the following command: rtmpdump -r $RTMPURL -v | mplayer -

-r tells rtmpdump the url of the stream

-v tells rtmpdump that the stream is a live stream

The | (pipe) directs stdin to mplayer and the – after mplayer tells mplayer to read data from stdin

Example: rtmpdump -r "rtmp://cp21366.live.edgefcs.net/live/Lou_KY_WTFX-FM_OR@s7696?auth=daEcEbgdNb4a3bdcKdYcrcgcGara0c1c3cZ-bmC7wi-4q-LM3Y9_7nqEDps4CCulBtyp&aifp=1234&CHANNELID=981&CPROG=_&MARKET=LOUISVILLE-KY&REQUESTOR=WTFX-FM&SERVER_NAME=p2.wtfx-fm.ccomrcdn.com&SITE_ID=2038&STATION_ID=WTFX-FM&MNM=2&TYPEOFPLAY=0" -v | mplayer -

Things to watch out for:

  • The RTMP url may change/expire. I have not been able to confirm this yet, but if the RTMP url changes you will simply need to open the url of the xml file (step 1) and copy the new rtmp url

Sources:

Maybe when I get some more time and become more ambitious I will write a small python wrapper that will extract the url from the xml file and start the stream.
