    Hi, how can change the mp3 bitrate, from 128 to 64 or 96 on airtime 1.70 o 1.6.1?

    Very Happy

    I tried to change the file ls_script.liq on airtime 1.6.1 with this new line

    ""
    if output_icecast_mp3 then
    out_mp3 = output.icecast(%mp3,
    host = icecast_host, port = icecast_port,
    password = icecast_pass, mount = mount_point_mp3,
    fallible = true,
    bitrate = 96,
    restart = true,
    restart_delay = 5,
    url = icecast_url,
    description = icecast_description,
    genre = icecast_genre,


    but the output was always at 128 Sad

    how can I do? thanks and sorry for the trouble!

    Your best bet is to look into the liquidsoap documentation to figure that one out...and if you do find out, please let us know!

    Hi Fabio,
    You're almost there.. once you edit that file, you need to copy it to /opt/pypo/bin/scripts and restart liquidsoap.

    Or you could just edit /opt/pypo/bin/scripts/ls_script.liq directly.

    bitrate = 96,

    This doesn't work with Liquidsoap 1.0.0-beta+svn (default@e712df4d96c0:20110501:162642), after adding the "bitrate" parameter, I get the following error in liquidsoap --check:
    At line 140, char 23-24: cannot apply that parameter because
the function (at line 136, char 29) has no argument labeled "bitrate"!
    Same for "quality" setting for the OGG stream.

    try putting it like this:

    if output_icecast_mp3 then
    out_mp3 = output.icecast(%mp3(bitrate=96),
        host = icecast_host, port = icecast_port,
        password = icecast_pass, mount = mount_point_mp3,
        fallible = true,
        restart = true,
        restart_delay = 5,
        url = icecast_url,
        description = icecast_description,
        genre = icecast_genre,
        s)

    Same thing, except change the line that says output.icecast(%vorbis)
    instead.

    I done ii in this way:
        out_ogg = output.icecast(%ogg(quality=-1.0),


    What's wrong?

    Hi,

    I haven't tested this, but try replacing "%vorbis" with "%vorbis.cbr" on line 74.

    It is works! Thanks you.

    But there are no meta tags Sad

    I don't know if the problem is standing on Icecast side (it looks like) or in client player side (I am using VLC, audacious)

    ogg metadata is turned off as it causes disconnects in some players.

    What's that language? - some words seem familiar : )
    Encoding of the title is screwed, looks like this now:

    Language - Polish.

    You said that ogg metadata is turned off.
    But I have in ls_script.liq this:

    if output_icecast_vorbis then
    
    if output_icecast_vorbis_metadata then
        out_vorbis = output.icecast(%vorbis,
                host = icecast_host, port = icecast_port,
                password = icecast_pass, mount = mount_point_vorbis,
                fallible = true,
                restart = true,
                restart_delay = 5,
                url = icecast_url,
                description = icecast_description,
                genre = icecast_genre,
                s)

        #remove metadata from ogg source and merge tracks to fix bug
        #with vlc and mplayer disconnecting at the end of every track
        s = add(normalize=false, [amplify(0.00001, noise()),s])
        out_vorbis = output.icecast(%vorbis,
                host = icecast_host, port = icecast_port,
                password = icecast_pass, mount = mount_point_vorbis,
                fallible = true,
                restart = true,
                restart_delay = 5,
                url = icecast_url,
                description = icecast_description,
                genre = icecast_genre,
                s)    
    end


    PS. I don't know how fix encoding.
