here is the code in C that prints out name of the song when mpd changes it.
#include <unistd.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <libmpd.h>
#include <debug_printf.h>
#define RED "\x1b[31;01m"
#define DARKRED "\x1b[31;06m"
#define RESET "\x1b[0m"
#define GREEN "\x1b[32;06m"
#define YELLOW "\x1b[33;06m"
void status_changed(MpdObj *mi, ChangedStatusType what)
if(what&MPD_CST_SONGID)
mpd_Song *song = mpd_playlist_get_current_song(mi);
if(song)
printf(GREEN"Song:"RESET" %s - %s\n", song->artist, song->title);
int main()
int run = 1, iport = 6600;
char *hostname = getenv("MPD_HOST");
char *port = getenv("MPD_PORT");
char *password = getenv("MPD_PASSWORD");
MpdObj *obj = NULL;
if(!hostname) {
hostname = "localhost";
if(port){
iport = atoi(port);
obj = mpd_new(hostname, iport,password);
mpd_signal_connect_status_changed(obj,(StatusChangedCallback)status_changed, NULL);
mpd_set_connection_timeout(obj, 10);
if(!mpd_connect(obj))
mpd_send_password(obj);
do{
mpd_status_update(obj);
}while(!usleep(100000) && run);
return 1;
to compile it:
gcc source_code -o output_file -lmpd -I/usr/include/libmpd-1.0/libmpd/
the code it's actually a modified example from libmpd site:
