    with the last version
    some functions have strange results...

    for example :

    music = playlist (mode='randomize',reload=1,reload_mode="rounds", "/srv/airtime/Jingles/")
    jingles = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/airtime/Musics/")
    mixed = rotate(weights=[1,4],[jingles,music])
    default = fallback([crossfade_airtime(mixed)])

    rotate doesn't work, weights is not respected...
    someone have an idea ?

    I do also experience troubles with my fallback.
    Although it's just a relay to another stream in the LAN, it doesnt work.

    I did uncomment this:
    default = amplify(id="silence_src", 0.00001, noise())
    ignore(output.dummy(default, fallible=true))

    and placed this:
    default = input.http("http://10.0.0.20:9000/TAGESPLAYLIST.ogg")

    before "ref_off_air_meta = ref off_air_meta"

    what do I do wrong? I don't want any rotation, just relay to our Music-Shuffling-PC.

    but I did! At least with 2.1 and a slightly different code ;-) as I see now.
    I think I used default = fallback (input.http("http://10.0.0.20:9000/TAGESPLAYLIST.ogg"))
    I go for my documentations from v2.1-times.
    But afaik I did it like shown in this article, adopted to http.input.
    Why should it not work? Liquidsoap offers plenty of input-sources?

  • You have only one input source into your fallback function?

    I'm doing something stupid

    music = playlist (mode='randomize',reload=1,reload_mode="rounds", "/srv/airtime/Jingles/")
    jingles = playlist(mode='randomize',reload=1,reload_mode="rounds", "/srv/airtime/Musics/")

    this line doesn't work :

    default = rotate(weights=[1,4],[promotions,crossfade_airtime(playlist (mode='randomize',reload=1,reload_mode="rounds", "/srv/airtime/Musics/"))])

  • I'm having trouble with this as well. I've edited the following in ls_script.liq:

    Original:
    default = amplify(id="silence_src", 0.00001, noise())
    ref_off_air_meta = ref off_air_meta
    if !ref_off_air_meta == "" then
        ref_off_air_meta := "Airtime - offline"
    end
    default = rewrite_metadata([("title", !ref_off_air_meta)], default)
    ignore(output.dummy(default, fallible=true)

    Edited: (Commented out the 'default' lines and 'ignore' line)
    #default = amplify(id="silence_src", 0.00001, noise())
    ref_off_air_meta = ref off_air_meta
    if !ref_off_air_meta == "" then
        ref_off_air_meta := "Airtime - offline"
    end
    #default = rewrite_metadata([("title", !ref_off_air_meta)], default)
    #ignore(output.dummy(default, fallible=true)
    default = playlist(mode='random', "/location/of/media")


    The above works for a while, but crashes eventually and wrecks the entire Airtime installation..
    Also, weirdly, the file '/etc/airtime/liquidsoap.cfg' disappears when this happens and 'ls_script.liq' won't function anymore at all.
    Only after a re-install via apt-get am I able to get things running again.

    Isn't there a better (foolproof) method of having a playlist play at all times?

    Update:
    Just FYI, Airtime crashed without this fallback playlist as well.
    And again 'liquidsoap.cfg' disappeared.. So after this crash it would't recover either, I had to reinstall.

    This was running on Ubuntu 12.04 LTS. I've now switched to Debian 6 and so far it's running okay using the piece of code I mentioned above.

    Update 2:
    I believe I've fixed my crashing problems as well. When broadcasting M4A (iTunes / AAC) files the memory usage raised dramatically. I'm now strictly broadcasting MP3 with no problems so far.

    Hi Albert!

    Have you managed to figure out about that strange errors?

    I'm also using a modified script, so I wouldn't update knowing there are issues with basic liquidsoap functions like rotate and others.

    Thanks.
