[FIXED] [2.0.3] Play music from a folder on silence won't work anymore - Airtime Support Discussions on Sourcefabric Forum

Hi there,

sadly i had to reinstall Airtime last week (hardware faulty), old version was 2.0.1 i think.

After installing, i recognized that the change in the ls_script.liq wont work anymore to play some music from a folder on silence.

What i found until now:

[ls_script.liq]

default = amplify(0.1, noise()) <- works

default = playlist(mode='random', "/srv/allmusic/") <- wont work

default = playlist("/srv/allmusic/") <- wont work

default = single("/srv/allmusic/01-somesong.mp3") <- work

default = playlist("/srv/allmusic/aplaylist.m3u") <- wont work

default = playlist(mode='random', "/srv/airtime/stor/imported/someband/somealbum/") <- wont work

default = single("/srv/airtime/stor/imported/someband/somealbum/02-anothersong.mp3") <- work

Also i noticed if default = playlist, the ls_script.log stays empty (no new entrys) - if default=single or amplify, the log file looks normal

Any ideas what i did wrong?

that's seems to be normal ;)
your ls_script is bugged
search ls_scrip on this forum you can see a lot of examples who explain how to do that correctly

Hi Albert,

thanks for your reply.

only thing i did is adding one of the lines above and commenting the original lines.

As i remember i did the same with the old version of Airtime.

Regards

EDIT:

Only usefull i found is http://forum.sourcefabric.org/discussion/13909 where it reads

default = playlist(mode='random', "/srv/airtime/stor/") :-( - also dont work

i don't get the idea where the error inside the ls_script should be... i only changed inside line 37/38

working:

.....

server.register(namespace="vars", "bootup_time", fun (s) -> begin time := s s end)

server.register(namespace="streams", "connection_status", fun (s) -> begin "1:#{!s1_connected},2:#{!s2_connected},3:#{!s3_connected}" end)

#default = amplify(0.1, noise())

default = single("/srv/music/01-Pirates-216kbps.mp3")

default = rewrite_metadata([("artist","Airtime"), ("title", "offline")],default)

s = fallback(track_sensitive=true, [queue, default])

s = on_metadata(notify, s)

....

not working:

....

server.register(namespace="vars", "bootup_time", fun (s) -> begin time := s s end)

server.register(namespace="streams", "connection_status", fun (s) -> begin "1:#{!s1_connected},2:#{!s2_connected},3:#{!s3_connected}" end)

#default = amplify(0.1, noise())

default = playlist(mode='random', "/srv/music/")

default = rewrite_metadata([("artist","Airtime"), ("title", "offline")],default)

s = fallback(track_sensitive=true, [queue, default])

s = on_metadata(notify, s)

.....

Here's what I use, Andreas:

ls_script.liq before modifications:
default = amplify(0.00001, noise())
default = rewrite_metadata([("artist","Airtime"), ("title", "offline")],default)

After modification:
#default = amplify(0.00001, noise())

#default = rewrite_metadata([("artist","Airtime"), ("title", "offline")],default)
default = playlist(mode='randomize', "/srv/airtime/stor")

Hope this helps.

Hi Wade,

sorry for the late reply - was out of the office.

Also tested your line - same result :( nothing is on air...

I remember i did the change exactly as you before we had the hardware problem and everything worked...

What version of Airtime you re using?

Regards

my ls_script correct (with hard crossfade) :

#default = amplify(0.00001, noise())
#default = rewrite_metadata([("artist","Airtime"), ("title", "offline")],default)

#s = fallback(track_sensitive=false, [queue, default])

drops = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/airtime/Drops/")
music = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/airtime/Musiques/")
jingles = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/airtime/Jingles/")
default = rotate(weights=[1,3,1,3], [jingles, music,drops,music])

def crossfade(s)
#duration is automatically overwritten by metadata fields passed in
#with audio
s = fade.in(type="log", duration=0., s)
s = fade.out(type="log", duration=0., s)
fader = fun (a,b) -> add(normalize=false,[b,a])
cross(fader,s)
end

s = fallback(track_sensitive=false, [queue, default])
enable_replaygain_metadata ()
s = amplify(1.,override="replay_gain",s)

s = on_metadata(notify, s)
s = crossfade(s)

FIXED!!!

dont know why your code wont work for me :(

BUT when i m using

default = playlist.safe(mode='randomize', "/srv/airtime/stor")

everything works... strange - didnt have to use .safe it before. Maybe i missed some changelog.

Thanks for all the help!!

Best regards,

Andreas

Reply to @Andreas+Bosl:I'm using 2.0.3 on my production server - the one from which I listed the modified script.

Howdy, Stranger!
