PyRadio 0.1

October 23, 2008

PyRadio is a console based Internet radio player. It is implemented in Python, and uses mplayer for media playback. Download version 0.1.

PyRadio has been tested under Ubuntu 8.10, but should run without any problems under most UNIX based operating systems. To get it running you’ll need Python and mplayer. Instructions are below:

Instructions

  1. Download PyRadio (you might need to right click on the link and select “save as”)
  2. Make the downloaded file executable. From the command line: chmod +x ./pyradio
  3. And run: ./pyradio

Code

The latest code available via GitHub.

  1. Nice app! Works fine on my OS X Leopard box.

    … and I like your taste in music stations. :-)

  2. Well, there is one problem: changing stations seems to leave behind an orphaned mplayer process, one for each previous station listened to. These processes are not shut down when pyradio is exited. I had to kill them manually.

  3. Hi,

    I have no specific request, I just wanted to say this project is very nice, especially on a netbook with low ressources.

    You may consider some coding-style issues, like naming a var str, as str is a type name (line 41), or adding some docstring for methods, or avoiding tabs (replace with 4 space chars) …

    But this is a nice project !

    Congrats

  5. Hmm … i like it (i a big fan of pure console) but i dont like that PyRadio leave running processes of mplayer … if you changing stations often and after you stop PyRadio then you have MANY mplayer processes left – thats no good i think …

  6. Some more info re those orphaned mplayer processes.

    I looked at the process tree with OS X’s Activity Monitor and noticed that the mplayer process created by pyradio was creating a second mplayer subprocess. It is this second subprocess which is orphaned after changing stations.

    The first mplayer process was killed as expected by the call to python’s os.kill( ) function.

    The “orphaned” process is actually shown as a child of launchd.

  7. If you use kill 15 (SIGTERM) instead of kill 9, the mplayer process will clean up any subprocesses it created.

    I have verified that this fixes the problem on OS X.

    Details of the fix:

    On line 87, replace
    os.kill(self.process.pid, 9)
    with
    os.kill(self.process.pid, 15)

  8. Great :) i follow CorkyAgain’s recipe that use kill 15 instead of kill 9 and it work’s here on linux – PyRadio is a sweet li’l script – i have added all my favo swedish radio stations to it too .. * POWER TO THE CONSOLE *

  9. Thanks for the feedback everyone! I’ve updated the code based on your suggestions, and the latest code is now on GitHub.

  10. Hi,

    I downloaded pyradio and ran it with python2.4. It came up okay. But, when I moved the highlighted line down to pick another station and pressed enter, it exitted with these messages:

    “File “/usr/lib/python2.4/subprocess.py”, line 542, in __init__ errread, errwrite)
    File “/usr/lib/python2.4/subprocess.py”, line 975, in _execute_child raise child_exception
    OSError: [Errno 2] No such file or directory”

    Any idea which file it was looking for? Thanks!

  11. Hi Than,

    I suspect that it can’t find “mplayer”, the media player that PyRadio uses for playback. If installing mplayer doesn’t fix the problem let me know.

    I’ll try to make the error message a little more readable in the next version!

    Thanks, Ben

  12. Hi Ben,

    Very nice and useful program.

    2 suggestions:

    1) A way to decrease/increase the volume, e.g. using ‘v’ and ‘V’ (these are the keys xine uses).

    2) Move the radio stations used to a config file, so that when we upgrade PyRadio, we don’t have to modify the source code each time to have our stations.

    Thanks for the nice app :)

  13. Hello Ben,

    very nice app. i could not play stations with the asx-ending.i added the -playlist option for mplayer in line 210, now that works too.

    thank you for pyradio!

  14. can we use the program on windows. if yes then what all changes I need to do for it to run on WinXP

    Comment by RedArc — February 3, 2009 @ 7:57 am

  15. @RedArc: I haven’t tried it on windows and to be honest I doubt it would run as is, but it should be possible to get it to run without any major changes. If you do try it please let me know how it goes. I’d be happy to help you out with any issues you might run into.

  17. Hi Ben,

    i’ve made some minor modifications to your script:
    I’ve added 3 radios which made my day happy.

    I also added a volume up and down funtionality by pressing the buttons “+” and “-”.

    Here you got the diff.

    Greetings
