Overview

An LED display built out of LED boards from some dead guy at TEP.

XMMS Plugin

Use the functions in xmms-1.2.11/libxmms/xmmsctrl.h to get data other than frequency and PCM data. Useful functions include:

gint xmms_remote_get_output_time(gint session);
gint xmms_remote_get_playlist_length(gint session);
gchar *xmms_remote_get_playlist_file(gint session, gint pos);
gchar *xmms_remote_get_playlist_title(gint session, gint pos);
gint xmms_remote_get_output_time(gint session);
gboolean xmms_remote_is_playing(gint session);
gboolean xmms_remote_is_paused(gint session);
gboolean xmms_remote_is_shuffle(gint session);
gboolean xmms_remote_is_repeat(gint session);
int xmms_remote_get_main_volume(gint session);
int xmms_remote_get_balance(gint session);
int xmms_remote_get_playlist_pos(gint session);

Data format streamed from the XMMS Plugin to user programs via named_pipes. There are two types of data: Information data about the state of XMMS and frequency data from the playing song. Each is preceded by an id number followed by the bytes of relevant data.

Frequency Data:
4 bytes: Id, which is 1 for frequency data
4 bytes: time into song in milliseconds
256 bytes: 

Info Data:
4 bytes: 1
second byte: length of title

Each named pipe should have only one user. The current named pipes are given below. Contact Lyric if you want one.
