in reply to MP3 server with IO::Socket

Does anyone know what meta data to send to send the name of the song to players like XMMS or winamp? I see how to send the station name, but I don't see how to change that between songs... Thanks!

Update: Ahh, I see. I had to add code to send out icy-metaint in the header, and then puncture the stream with that meta data. There is a good description here:

and here at

New Question Does anyone know how to downsample the MP3 that is being streamed here by the Perl Monkey code? Thanks!

    Further icy headers that winamp looks for, not sure about xmms. just replace your current headers with the below content.
    print $socket "ICY 200 OK\r\n"; print $socket "Content-Type: audio/mpeg \r\n"; print $socket "Cache-Control: no-cache \r\n"; print $socket "Pragma: no-cache \r\n"; print $socket "Connection: close \r\n"; print $socket "icy-name: Fuelradio \r\n"; print $socket "icy-genre: Techno \r\n"; print $socket "icy-url: \r\n"; print $socket "icy-notice1:This stream requires Winamp \r\n"; print $socket "icy-notice2:Perl Streamer v0.1a \r\n"; print $socket "icy-metadata: 1 \r\n\r\n";
    additionaly you can add
    print $socket "icy-metaint:8192\r\n";
    althoug my tests with the metaint caused alot of skipping and chirps, maybe someone can shed some light on the proper interval, im sure its different than 8192 since the mp3's are not being decoded and re-encoded within the scope of the app, there just being shoved down the throat. Anyone have ideas on how to do title streaming (i.e. showing what song is playing in the winamp/xmms title bar) maybe a id3 lib for perl??
      Altho' I've not done any structured testing ( and i use XMMS ), I've notices some mp3's titles appear and some dont. I'm taking a guess here, but i think it could be ID3 tag related..

    As well as that, I am interested in creating a buffer to allow more connections.

    I tested this script with 4 connections at a stream rate of 128kbp for the MP3's i have
    They said it would stall every couple of minutes
    I am gonig to be working on this tomorrow in case any monks have ideas
