Romain Beauxis updated LS-349:
------------------------------
Summary: Finer-grained display of on_air informations (was: command
server bugs)
Issue Type: Improvement (was: Bug)
Reporter: anonymous
Priority: Minor (was: Blocker)
This is not really a bug but I understand that it can be confusing.. You can
have a better handling of the current song by using on_metadata on the last
source before the output.

> Key: LS-349

> Project: Liquidsoap
> Issue Type: Improvement
> Components: Liquidsoap
> Affects Versions: 1.0 beta
> Reporter: anonymous
>
> Hello, I'm using the command server (telnet) to feed a web panel with the
> status of the radio.
> My radio plays a randomized playlist source and has a request queue source.
> When there is a request on the queue playing the on_air command outputs both
> IDs, the one in the playlist and the one on the queue head.
> An example output follows
> ---------------------------------------------
> on_air
> 48 47
> END
> trace 48
> [2010/01/01 10:21:02] Pushed ["/opt/storage/share/Music//OverClocked ReMix
> OCR01001 to OCR01900/Final_Fantasy_6_Seized_with_Fury_OC_ReMix.ogg";...].
> [2010/01/01 10:21:11] Currently on air.
> END
> trace 47
> [2010/01/01 10:20:32] Pushed ["/opt/storage/share/Music/OverClocked ReMix
> OCR00001 to
> OCR01000/Final_Fantasy_6_Dancing_Madly_(Second_Form)_OC_ReMix.ogg";...].
> [2010/01/01 10:20:32] Entering the secondary queue.
> [2010/01/01 10:26:32] Entering the primary queue.
> [2010/01/01 10:26:42] Currently on air.
> END
> ------------------------------------
> This of course messes up my web panel since the song playing is not 48 but 47.
> Also if I issue a radio(dot)ogg.skip command it skips both sources and plays
> the new one in the playlist not the new one in the queue.
> I don't know if this is a bug in my script but it's based entirely on the
> advanced case study script on the site.
> script follows
