Description
|
||||
===========
|
||||
This is a pseudo streaming audio server. It supports the shoutcast protocol for certain players. This will output streaming mpeg for all other players.
|
||||
|
||||
The script does not accept a single audio source, but uses lose audio files instead. It employs a trick to keep all the listeners in sync. Through a shuffled playlist with a fixed seed value, the script will always serve the same audio at the same time.
|
||||
|
||||
The advantage is low processor usage, because the audio had not to be transcoded on the fly.
|
||||
|
||||
Shoutcast protocol
|
||||
==================
|
||||
The protocol is a bit of a hack. It's quite simple but there is almost no documentation on the interwebs. The protocol consists of two part: the mpeg audio and the metadata.
|
||||
|
||||
Audio stream
|
||||
------------
|
||||
The stream is just a simple dump of concatenated MP3 files. To make it a bit more of a 'protocol' the header and the id3 tags are stripped of the file. So only the audiodata of a MP3 file used.
|
||||
|
||||
The metadata
|
||||
------------
|
||||
Was a bit of a challege to reverse engineer. This was badly documented.
|
||||
|
||||
The raw audio stream (without headers and id3-tags) is spliced into chuncks the size of the buffer. The size is specified in the icy-metaint variable in the http header. Then the metadata is inserted at these point in a certain format. The metadata must have this payload:
|
||||
|
||||
StreamTitle='Artist - Song';
|
||||
|
||||
and has an null-character (0x00) to end the string. The string must be padded to the next 16th position. So the example has 28 character + 1 null-character. Makes: 29 characters. You'll have to append 3 extra null-characters.
|
||||
|
||||
Setup
|
||||
=====
|
||||
Your audio must be transcoded to MP3 in your transmission bitrate. Please normalize and trim your audio to avoid silent parts. Put the audio in the music folder.
|
||||
|
||||
music.db
|
||||
--------
|
||||
If the music.db is present it must be deleted after every change. This is a cache-file for the metadata of the audio.
|
||||
|
||||
Config
|
||||
======
|
||||
|
||||
Edit the settings in the index.php
|
||||
|
||||
This is an example:
|
||||
|
||||
$settings = array(
|
||||
"name" => "Radio Demo", //Name of your radio station.
|
||||
"genre" => "Classic", //Does not have to be a MP3 genre, can be anything.
|
||||
"url" => $_SERVER["SCRIPT_URI"], //URL to the station, this is automatic generated by PHP.
|
||||
"bitrate" => 96, //Bitrate in kbps of the transmission. All audio but be transcoded to this bitrate.
|
||||
"music_directory" => "music/", //Folder where the audio is.
|
||||
"database_file" => "music.db", //Cache filename of the audio metadata.
|
||||
"buffer_size" => 16384, //Buffersize of the icy-data, not really important. Bigger buffer is less updates of the current song name.
|
||||
"max_listen_time" => 14400, //Maximum listen time of a user in seconds. Set to 4 hours.
|
||||
"randomize_seed" => 31337 //The seed of the pseudo random playlist. Must be set to a contant otherwise the clients won't be in sync.
|
||||
);
|
||||
|
||||
Usage
|
||||
=====
|
||||
Point your audio player to the URL where you have installed this script.
|
||||
|
||||
