We do this all the time, but using an external player called via
Rivendell macro scheduled in the log. We've done it using both
"mplayer" and "vlc" players installed in our Linux OS.
Typically we end up putting it in a small script to handle odd events
like figuring out the audio routing of it or dealing with stream getting
disconnected and such. We also are running Jack audio, so it simply
shows up as a jack client and we route it to our broadcast output. If
you aren't using Jack, then you can dedicate an output to an external
audio switcher that you then command it from Rivendell to switch over
and back when you need to.
Typically we start the player playing the stream a few seconds before it
is needed then have a hard-timed macro put it on the air at the exact
time we need. Note there is typically a delay caused by the buffering
action of the player (that can often be adjusted), that you might have
to deal with.
The service we usually receive also sends sub-audible (25/35hz tones) to
trigger breaks and program end events that we also send through an
external tone decoder because I haven't yet found a way to process these
tones internally in software although I would think some tight filtering
with a Jack client and the use of silence-jack might work. If you only
need to stop the broadcast at a certain time, them another hard-timed
macro that kills you player and re-routes the audio will do it.

Hello,
I was wondering: is it possible to set up a cart which can play a stream? For
example: I know there's a stream at stream.radio.com:9000 (or something like
that), and I want to play that stream on my station. Can Rivendell handle this
in some kind of way? The Operations Guide doesn't say anything about this, but
I kinda need to know this. If it's not possible, I'll have to instruct someone
to connect a laptop to the line-in of the mixer.
The reason (for if you're wondering): the major will be speaching somewhere and
we'll be broadcasting that live. The location has a live-stream which we can
pick up. If I can create a cart that will play this stream, things will be much
easier. In the future we will have to do similar things more often. In the
past, before we started using Rivendell, we also had a way to do this.
Sincerely
Peter van Embden
