Xspf autoplaylister
ein aus der windows command shell ausführbarer, scriptbarer xspf autoplaylister. hilft beim rekursiven erstellen von xspf playlists in großen mediensammlungen. funktioniert prima in verbindung mit flashplayern wie z.b. dem jw player.
ich habe vor kurzem Charlie Craigs xspf-playlister von vbs nach js (mit ActiveX und in verbindung mit MP3Tag.dll, also nur unter windows lauffähig) portiert und noch ein paar funktionen hinzugefügt. ursprünglich wollte ich ein utf-8/unicode problem, das beim auslesen der id3 tags von mp3-dateien auftritt, lösen, was mir in vbs zu schwer war; leider funktioniert das immer noch nur bei 2 bytes langen chars, also bis 0xff, d.h. japanische schriftzeichen etc. werden aus den tags immer noch nicht korrekt ausgelesen (die dateinamen können alle schriftzeichen, die in windows möglich sind enthalten und werden korrekt wiedergegeben).
wie auch immer: da ich selber ewig nach einer vernünftigen, scriptbaren lösung für den lokalen einsatz ohne php gesucht habe und es wirklich nur sehr wenig brauchbares in der richtung gibt, dachte ich, ich poste den code, für den fall, dass jemand so etwas sucht.
zur bedienung:
• einmalige vorbereitungen:
- besorge Dir die MP3Tag.dll
- die dll in ein verzeichnis ablegen, in dem sie permanent aufbewahrt werden soll
- die dll registrieren (in der kommandozeile
- den untenstehenden javascript code als *.js datei speichern
• im windows explorer: das verzeichnis mit den mediendateien auf die .js-datei ziehen und loslassen. doppelklick auf die datei gibt ein hilfe-fenster aus.
• in der windows shell:
für hilfe zur bedienung:
beispiel:
• folgender shell befehl
erzeugt für jedes unterverzeichnis des aktuellen verzeichnisses eine xml playlist die so aussehen könnte:
man beachte, dass beim zweiten track die sonderzeichen, die aus den id3 tags ausgelesen wurden, verstümmelt, die aus dem dateinamen und -pfad ausgelesenen sonderzeichen jedoch korrekt dargestellt werden.
also dann, hier kommt das script. viel spaß damit.
viele grüße

/******************************************************************
* :: AUTHOR :: based on vbs by charlie craig (http://www.iol.ie/~craigcharlie/blog/2006/04/xspf-mp3-playlister_06.html),
* which was based on php by la_boost (http://www.interclasse.com/scripts/ Mp3Playlister_singleList.php),
* char conversion by richard ishida (http://rishida.net/scripts/uniview/conversionfunctions.js).
*
* :: HOWTO :: installation: get the MP3Tag.dll from http://www.iol.ie/~craigcharlie/blog/
* and follow instructions to register the dll.
* start the script from shell by typing
* cscript ID3_XSPF_Playlister.js --usage
* or by doubleclicking on the script file for
* instructions on usage
*
* :: DATE :: 06-22-2009
*
* :: VERSION :: 0.2
*
* :: TODO :: 1) better checking of args
* 2) there should be a switch to only write the list
* to screen, not to fs. (:: DONE::)
* 3) maybe a user definable regex feature that guesses
* title info from file path for files that do not
* have readable id3 tags
* 4) instead of the binary silentoverwrite(true/false) a
* dialogue controlled overwrite(yes/no/don't bother
* me anymore)
* 5) the MP3Tag.dll unfortunately seems to mix up hex and
* utf-8, so that e.g. "?ô?" in the artist tag comes
* out as ",ôn" in the playlist. i initially did the
* translation iot include richard ishidas encoding
* conversion functions (which would have been a real
* hassle to implement in vbs, at least to me), to
* re-translate the misspelled characters. turns out
* this is not possible due to information loss by
* cutting off parts od the hex code points. bummer.
* at least it replaces the more common chars up to
* 7 bit correctly.
*
* if anybody finds a dll or other solution that can
* handle this encoding issue, please drop me a line
* at goetz.freytag_ät_gmail.com
*
* :: BUGS :: probably. please tell me if you find one.
