Oh, and the volume is almost nill on some of the local streams that use it.
I know there's probably an inaccessible turn it up button, even replay AV in
Windows can't seem to do it using winpcap. Maybe it's ssl too?

Hi,
Apologies if this has already been answered.

I'm trying to locate a tool which when given a web page with a "Listen

If the "listen live" link actually points to a playlist file (.pls, .m3u,
.ram, .asx, .wax, .xspf etc), you can configure mplayer to just deal with
these by configuring the appropriate mime type to launch mplayer with
the -playlist option.
My problem as you will doubtless surmise, is finding the actual
URLs of audio streams.
Ideally I'd like a tool which I can use like this:
$ get_audio_url http://www.wabcradio.com > url.txt
It would be pretty much impossible to write a tool to do this, and in fact
the site given above is a good example of exactly why it would be
impossible.
On www.wabcradio.com, the "listen live" link on the front page actually
links to another page on the site, not to the stream directly. The actual
listen link is on this second page.
Furthermore, the actual listen link, when you get to it, actually opens
another page using some javascript. The page it actually opens is
http://player.streamtheworld.com/_players/citadel/?sid=826&nid=2920
This page uses more javascript to load up a flash-based stream player, and
even reading the source code does not clearly reveal the stream URL.
It might be possible to find it by closely examining the code on this page
and reading some of the javascript files it includes, but I've not a mind
to do that right now.
Given that finding this is hard enough for a human to do, and this kind of
obscurity is designed to stop humans from finding it, trying to write a
program to do it would be more work than just digging up the URLs from the
pages in question, assuming it can in fact be done at all.
Geoff.
