Id3 Tags, Muetze1's Lib

[Muetze1]

1. Ich weiss nicht, ob die anderen soviel Wissen über meine Lib haben, als dass du direkt hier nachfragst.
2. Die Reihenfolge der Tags sind immer völlig zufällig - so wie sie aus dem MP3 gelesen werden. Der TTxxxTag handelt dabei alle Text-Tags die unterschiedliche Informationen beinhalten. Wenn du die Inhalte unterscheiden willst, dann schau dir an was in der Eigenschaft TagID drinne steht. Hier mal eine kurze Liste der unterschiedlichen Bedeutungen (übrigens auch zu finden in der ID3v2Types.pas aus der Library):

(Diese Tags werden mindestens mit der TTxxxTag Klasse behandelt (sprich: gelesen/geschrieben))...

Somit findest du das Genre immer in dem TTxxxTag, welcher eine TagID von 'TCON' hat. Wenn kein TTxxxTag mit dieser TagID vorhanden ist, dann leg eine an mit dem TagDispatcher der Library.
