[Savonet-users] Output status information

[Nicholas Vrtis]

This is just a test script, but if I do something like this:

#!/home/liquidsoap/.opam/system/bin/liquidsoap
set("log.file",false)
set("log.stdout",true)
set("server.telnet", true)
# Need to use external address to listen on, so we can talk from external
# set("server.telnet.bind_addr","192.168.0.140")
set("server.telnet.bind_addr","192.168.0.134")
# Don't time out the telnet server
set("server.timeout",-1.0)
alsaDevice = ref "hw: Set"
s = single(id='theSingle',"FirstTest.mp3")
# This will give liquidsoap something to do while we wait for the telnet
commands
thedummy=output.dummy(id='dummyAudio',blank())
thelocal = output.alsa(id='localAudio', device="#{!alsaDevice}",
fallible=true,s)

Then in telnet I have commands which will 'list' all the outputs that have
been created.

I can also issue the telnet commands:
localAudio.status
localAudio.stop
localAudio.start

I have been beating my head trying to find how to get the same information
within a liquidsoap script.

How do I get a list of all the currently created outputs?

How can I tell if they are running or not?

How can I stop/start them (the telnet command localAudio.stop is different
than source.shutdown(thelocal). Shutdown destroys the output, but stop
simply stops sending bits out.

I must be looking at the wrong spots, but I have been pouring over the API
for quite a while and have not found anything to do this.

Thanks. Nick

If you are confident with using the server, then you should be able to
execute the same calls in your script:
server.execute("localAudio.status")
server.execute("localAudio.start")

etc..

Thank you. ! I didn't connect the server meant the same server that Telnet
uses. This should get me going. Thanks a lot
