ffmpeg flac to aac (libdfdk_aac) fehlende Metadaten

Ich möchte ein Album von Flac in AAC konvertieren. Nach dem Konvertieren der aac-Datei fehlen alle Metadaten der ursprünglichen flac-Datei. Ich habe schon versucht, es mit dem -map_metadata 0Argument zu konvertieren

Mein Befehl sah so aus:

ffmpeg -i input.flac -c:a libfdk_aac -b:a 320k -map_metadata 0 output.aac 

Die Ausgabe:
