Screen API changed a bit: now size args are taken from init(w,h) screen implementations should provide an _init(w,h) as well constructors are without arguments (as in the rest of freej)

"""
|
|
Classes to make a continuous video stream playlist from an RSS feed.
|
|
The script is planned to be a useful tool for video online databases as
|
|
http://giss.tv/dmmdb and plumi.org based sites to be able to do
|
|
continuity tv channels on the internet.
|
|
|
|
The script takes a an argument the URL of the RSS feed. If it's not specified will
|
|
fetch http://giss.tv/dmmdb/rss.php?channel=piksel08 by default.
|
|
|
|
In order to run the script you need RSS.py, and rss parser you can found here::
|
|
http://www.mnot.net/python/RSS.py
|
|
|
|
The script is still not functional as we need new features on the freej core and
|
|
in the freej python bindings. But it's an example as a simple user case and as
|
|
feature request need example ;)
