On va devoir utiliser RDAdmin → Manage Hosts → ordinateur sur lequel tourne le programme → RDAirplay Là on clique sur Now and Next. Ensuite on va charger un module.
Nous allons charger le module rlm_urlwrite.rlm
Si vous ne l'avez pas vous pouvez le compiler à partir de ce code https://github.com/ElvishArtisan/rivendell/blob/stable/rlm/rlm_urlwrite.c

Puis dans le champ argument nous allons faire pointer vers le fichier de configuration du rlm que l'on va nommer rlm-urlwrite.conf
Pour plus de facilités on mettra le .conf dans le même dossier que les rlm (/usr/lib64/rivendell dans la version 2.19.3.1)
La structure du .conf se trouve aussi sur git hub https://github.com/ElvishArtisan/rivendell/blob/stable/conf/rlm_urlwrite.conf
Mais pour faire simple
; rlm_urlwrite.conf ; ;fichier exemple de configuration. Faire autant de section [url] que vous avez de fichier à envoyer ;enlever le point virgule devant une ligne pour l'activer ; Section Header ; [Url1] ; Url ; ; L'url vers laquelle vous envoyez le fichier. Elle peut être de la forme suivante ; file:// ; ftp:// ; http:// (uses the PUT method) ; sftp:// ; Url=sftp://server.exemple.com:portdestination/titre_encours.txt ; Username ; ; Votre nom d'utilisateur ; Username=votrenom ; Password ; ; le mot de passe que vous utilisez Password=motdepasse ; Format String. Le format avec lequel les informations sont écrite dans le fichier texte. ; FormatString=NOW: %d(ddd MMM d hh:mm:ss yyyy): %t - %a\nNEXT: %D(ddd MMM d hh:mm:ss yyyy): %T - %A\n ; Encoding. Definir si certains caractère doivent être ignorés. ; les options sont les suivantes ; ; 0 - tous les caractères sont pris en comptes. ; 1 - "XML" escaping: Escape reserved characters as per XML-v1.0 ; 2 - "Web" escaping: Escape reserved characters as per RFC 2396 Section 2.4 Encoding=0 ; Log Selection ; ;Détermine dans quel log les informations vont être lues ; Yes', 'No' or 'Onair'. ;Si sur 'Onair', le fichier ne prendra en compte que les morceaux passer avec le flag On Air ;si l'option est active dans RDAirPlay MasterLog=Yes ;Aux1Log=Yes ;Aux2Log=Yes ; D'autres fichiers peuvent être envoyés il suffit de respecter cette syntaxe de fichier ; ;[Url2] ;Url=file:///home/rd/somefile.txt ;Username=janedoe ;Password=crackme ;FormatString=%t by %a\r\n ;Encoding=0 ;MasterLog=Yes ;Aux1Log=No ;Aux2Log=Onair
Faire un CRON sur votre serveur qui lancera le script de mise à jour de votre base de données toutes les minutes.
Ce script peut ressembler à ça
<?php
try {
// On ouvre le fichier en lecture
$fichier = fopen( '/chemin/sur/mon/serveur/titre_encours.txt', 'r' );
// On récupère la première ligne
$encours = fgets( $fichier );
// On ferme le fichier
fclose( $fichier );
// Connexion MySQL
$options[PDO::ATTR_ERRMODE] = PDO::ERRMODE_EXCEPTION;
$options[PDO::ATTR_DEFAULT_FETCH_MODE] = PDO::FETCH_OBJ;
$bdd = new PDO( 'mysql:host=serveur ;dbname=base ;', 'identifiant', 'password', $options );
// Vérifies si le titre existe depuis 120 minutes (au cas où)
$requete = $bdd->prepare( '
SELECT titre
FROM wp_playlist
WHERE
titre = ?
AND `date` > NOW()-INTERVAL 120 MINUTE;'
);
$requete->execute( array( $encours ) );
// Si le titre n'existe pas on le crée
if( !$requete->fetchColumn() ) {
$requete = $bdd->prepare( '
INSERT INTO wp_playlist ( titre, `date` )
VALUES ( ?, NOW() );'
);
$requete->execute( array( $encours ) );
}
}
catch(Exception $e) {
// On crée ou on ouvre le fichier de log
$fichier = fopen( 'log.txt', 'a+' );
// On stocke l'erreur
fputs( $fichier, date('Y-m-d H:i').' - '.$e->getMessage()."\n" );
// On ferme le fichier
fclose( $fichier );
}
?>
