Change mp3 bitrate
  • 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)

    Thank you James, I appreciate! It works.
  • How do with OGG quality ??

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

  • But this hang up me AirTime.

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


    What's wrong?

    Try this way:

    out_ogg = output.icecast(%ogg(bitrate=64),

  • No it still not working

  • What is on line 74 in ls_script.liq?
  • I attached above all ls_script.liq file.
    Here you have something more comfortable check this http://wklej.org/id/585194/
  • 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

    http://play.bieszczady.fm:8000/

    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:
    Bézèd'h - Les filles sont volages
  • 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)
    
        else
            #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,

                    restart = true,
                    restart_delay = 5,
                    url = icecast_url,
                    description = icecast_description,
                    genre = icecast_genre,
                    s)    
        end


    PS. I don't know how fix encoding.
