Hi all !
So I now have a working like s4shout GUI for liquidsoap. Features are:
- add/remove a server (server, port, password) in the link list.
- start / stop for the selected link.
- link status are updating every x second
- if liquidsoap crashes (or the computer is rebooted), at launch time,
s4shout reads its XML config file and populate the link list from scratch.
. I know have to face following problem:
* When s4shout adds a "link", it sends to liquidsoap (by a telnet socket):
dynamic_playlist.start pulse|server|port|password|XXXXXX
where XXXXXX is a UUID representing the "link" unique ID. Then in the
.liq script I am using:
output = out(id="#{stream_id}", host="#{stream_host}",
port=int_of_string("#{stream_port}"), password="#{stream_password}", s)
Note that I have also added start=false in the output properties, so
liquidsoap doesn't try to start a connection by himself.
What I don't understand is if the connection fail, liquidsoap retry
every 3s ... but I haven't specified any "restart" properties and it
seems to be "false" by default ?
While liquidsoap is in this "retry every 3s" loop, the status of the
link is still "on", which is logical assuming "retrying" being kind of
"started"... So the question is again: what's the best practice ? Do
you think I have to handle re-connection from s4shout ? in which way ?
Thanks !
