[Savonet-users] Play OnDemand

[Chris E. <chr...@gm...>]

Hi Folks, I put together a quick on_demand function using some posts
from previous discussions on this list.  But I'm not sure how to get
this on_demand stream to stop and shutdown when the single track or
playlist is over.  As it is written, the request.dynamic source will
loop indefinitely and only stop with explicit call to name.stop via
the telnet interface.  Any tips from other users out there?

dyn_out = output.icecast(
  %ogg(%vorbis(quality=1)),
  host = "<ip_address>",
  port = <port>,
  password = "<passwd>",
  genre= "Mixed",
  url= "http://vinylproject.com",
  fallible=true
)

def play_on_demand(sname)
  s=request.dynamic({request.create("/path/to/myfile.mp3")})
  # Dummy stop function
  f = ref { () }
  output = dyn_out(
      mount = (sname ^ ".ogg"),
      description = "On demand " ^ sname ^ " Liquidsoap Controller",
      name = sname ^ " Stream [ogg 1.0] - provided by liquidsoap",
      on_stop = { f = !f; f() },
      s
  )
  f := { source.shutdown(output) }
  "ok!"
end

server.register(
  namespace="ondemand",
  usage="play <stream_name>",
  description="Play URI on demand. Creates a new icecast mount to play",
  "play",
  play_on_demand
)
