Ø Can I use silentjack to start RDAirplay automaticaly and how is this done?
Sure, I do. Our main system uses the silence since on a broadcast tools 8.2
switch, but we have a backup that uses silentjack:
I startup silentjack with a line like this:
silentjack -q -c rivendell_0:playout_0L -n Silence_Alarm -p 5 -g 60
silence_alarm
So this assumes I'm listening to "Rivendell_0:playout_0L" as yours might be
different, then it calls a script I wrote called "silence_alarm".
In "silence_alarm" is a lot of logic to sort through different issues that can
cause silence on our station (such as problem Internet feeds), but here is the
part that handles a crashed rdairplay:
#!/bin/sh
if ( ! ps -C rdairplay > /dev/null 2>&1 ) ; then
rdairplay &
sleep 7
echo LC BLACK Restarted: `date +'%b-%d %T'`'!' > /dev/shm/restart
rmlsend --from-file=/dev/shm/restart
sleep 15
rmlsend PB\ 1!
sleep 30
fi
Save this to a file somewhere like /usr/local/bin and mark is executable with
"chmod +x silence_alarm"
So what this does is checks to see if rdairplay is running, and if it isn't, it
starts it. I also have it leaving a message about this in /dev/shm/restart
(which is a ramdisk-like space on my Debian system, you may need to save it
elsewhere), and then also sends it to the "label" area of rdairplay so that
there is notice that this happened and when.
Finally after the rdairplay gets running and its log automatically gets
reloaded, it starts is playing again with the "PB 1!" command.
