streamtuner2
============

ST2 is a internet radio browser. It queries online directories like
shoutcast and xiph.org for music stations.

It mimics the original streamtuner application to some extend. It's
however writting in Python instead of C now.


how to run
----------

You can just execute the main binary "st2.py". All the other files
need to be copied into /usr/share/streamtuner2/ however. If it
doesn't work, make sure you have Python and gtk/pygtk installed:

  sudo apt-get install python python-gtk2 python-glade2 python-xdg


The *.glade file represents the GUI.  So if you have the glade-3
application installed, you can inspect and enhance the interface.
Give it a try, report back.


development state
-----------------

There was a lengthy development pause, actual maintenance time of
this application is probably 2-3 months now. However, it is mostly
feature-complete meanwhile. The internal application structures are
somewhat settled. Some modules are still pretty rough (json format,
http functions), and especially the action module for playing and
recording isn't very autonomic (though has some heuristic and uses
stream format hints).

The directory modules mostly work. If they don't, it's just a
matter of adapting the regular expressions. Shoutcast and Live365
lately changed the HTML output, so broke. Therefore PyQuery parsing
methods were implemented, which extract stream info from HTML soup
using CSS/jQuery selectors.
And it should be pretty easy to add new ones. There will also
somewhen be a feature to add simple station 'scripts'; in testing.


comparison to streamtuner1
--------------------------

Streamtuner1 has been written around 2002-2004. At this time it was
totally unfeasible to write any responsive application in a scripting
language. Therefore it was implemented in C, which made it speedy.

Using C however has some drawbacks. The codebase is more elaborate,
and it often takes more time to adapt things.

Personally I had some occasional crashes because of corrupt data
from some of the directory services. Because that was more difficult
to fix in C code, this rewrite started. It's purely for practical
purposes, not because there was anything wrong with streamtuner1.

streamtuner2 being implemented directly in Python (the C version had
a Python plugin), cuts down the code size considerably. It's much
easier to add new plugins. (Even though it doesn't look that way yet.)

For older machines or netbooks, the C streamtuner1 might overall
remain the better choice, btw. Running inside the Python VM makes this
variant more stable, but also way more memory hungry. (This has been
reduced with some de-optimizations already.)

-------------

If you are looking for a lightweight alternative, Tunapie is still
in development, and it has a working Shoutcast+Xiph reader.
http://tunapie.sourceforge.net/

Streamtuner2 CLI can also be used as proxy server for streamtuner1.
There is a wrapper available. But there was nobody yet to be found who
wanted set it up globally. (Else streamtuner1 would just require a patch
in /etc/hosts to work again.)
It's available as st1proxy.tgz and cli-mode-only.tgz from
http://milki.erphesfurt.de/streamtuner2/ext/
Contact me for setup help. Requires a webserver with unrestrained
vhost support.
