[Linux-disciples] Evaluating a Javascript function

[Adam Rosi-Kessel]

You probably need to save the .js file from NPR locally, and edit it to
display the ultimate URL to the screen, e.g., with a document.write()
function call.  You will then be able to see the URL and copy it into
your grabber.

You should also be able to see the URL of the current stream *from*
realplayer.

This isn't really scriptable as it is now, since wget et al. won't be
able to parse the JavaScript.  To do that, you'd have to rewrite the NPR
JavaScript file as PHP/Perl or whatever.  It's kind of a pain.

Another option is capturing the output from RealPlayer, or using mplayer
as your RealPlayer plugin and having *that* record to file.
