Hi everybody ;)

I've a little request, question ;)

how can I stream into airtime during a specific time ?

for example :

I need to rebroadcast a stream from 17h00 to 17h10, every day

Martin Konecny

Take a look at this page:

http://savonet.sourceforge.net/doc-1.0.0/complete_case.html

Where they first use a switch. You can see that the switch will decide which source to use depending on the time of day. So that solves your time problem.

Now you just need to make an input.harbor source, and connect this source to the switch.

Albert FR

I'm thinking about that, effectively, but with ls_script is not so simple to adapt ;)

Martin Konecny

If you visualize the whole source and sink as tree you will see you only need to put this switch near the sink (icecast outputs)

Albert FR

I'm trying that this Week End ;)

I'm trying that, but whit no success...
any ideas ?

rfi= input.http("http://stream.rfi.fr/rfi.mp3")
morning= playlist(mode='randomize',reload=1,reload_mode="rounds", "/home/airtime/Musique/")
night= playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/airtime/stor/imported/")

default=fallback([ request.queue(id="request"),switch([({ 6h-18h }, morning),({ 18h-21h05 }, night),({ 21h05-21h15 }, rfi),({ 21h15-6h }, night)])])

my bad,

rfi have a bad adress translation, and liquidsoap don't really like that
if i give the ip, that's working fine ;)

but ...

stream don't stop :( at the end of switch time...

any idea ?

David Slevin

Hi there...

Would I be correct in thinking that I can set up a situation where, when IceCast detects a source (possibly an incoming stream), it can switch that source to it's output?

So I could make either the output from the scheduler the default source or the "live" broadcast stream the default. One flipping to the other depending whether it's on or not.

That way, unlike Albert I need not worry about switching over at specific times!!!

Cheers...

Martin Konecny

Hi David,

You can do that using input.harbor with a fallback switch.

When someone connects to the input.harbor using mixxx (or some other source), liquidsoap will automatically switch over and use that as a source.

As I mentioned, we are implementing this in Airtime 2.1. This will all be configurable from the interface, and you will also be able to disable the live source if a 3rd party forgets to disconnect.

Albert FR

the question is : automated disconnect is it possible ?
I'm thinking yes, but i'm searching how to do that ;)

If you have an idea Martin ;)
I'm listening ;)

Albert FR

it seems necessary to make the source of the stream fault compliant with

({true},request.queue(...))

someone have an idea ?

I'm in the dark...

James Moon

Hi Albert,

Automatic disconnection on which source? Can you explain this in more detail?
I'm not sure what you are trying to achieve.
Thank you.

Albert FR

in this case rfi stream

James Moon

Automatically disconnect on what condition?

Albert FR

as you can see here :

default=fallback([ request.queue(id="request"),switch([({ 6h-18h },
morning),({ 18h-21h05 }, night),({ 21h05-21h15 }, rfi),({ 21h15-6h },
night)])])

after a certain time of diffusion

James Moon

So This is what you want:

6h-18h => morning
18h-21h05 => night
21h05-21h15 => rfi
21h15-6h => night

But when airtime is playing something(if request.queue has something to play), it will override any of above sources.

Is this what you trying to do?

Albert FR

almost ;)

the thing i want is rfi stream only for ten minutes
and after come back on radio airtime or night or day

James Moon

hm.. I'm not sure why it would play more than 10 mins. Have you look at the ls_script.log file and try to find any hints?

Albert FR

nope

but now i have another error :(

2012/03/09 01:24:25 [decoder:3] Unable to decode stream of type "audio/mp3"!

really strange before upgrade to 2.0.2 that's worked

Albert FR

perhaps a beginning of solution, but i don't understand why my mp3 stream is now none decoded :(

default=fallback(track_sensitive=false,[ request.queue(id="request"),switch([({ 6h-18h }, morning),({ 18h-21h15 }, night),({ 21h35-21h55 }, rfi),({ 23h15-6h }, night)])])

i've add track_sensitive function

Albert FR

Hi everyone !

Romain Beauxis from Savonet give me the solution :

"

This happends because the switch waits for the end of current track to
switch to another source. However, live source do not have tracks..
Therefore, you need to add track_sensitive=false to your switch.

Please note, however, that you may not need a track_sensitive=false
for the whole switch. In this case, you may create a source for rfi
seperatly like this:
  rfi = switch(tracks_sensitive=false, ({ 21h-21h10 }, rfi))

and plug this into your main switch:

default=fallback([ request.queue(id="request"),switch([({ 6h-18h },
morning),({ 18h-21h }, night),({ true }, rfi),({ 21h10-6h },
night)])])

Romain"

Howdy, Stranger!
