Hallo,
ich habe hier einige 6.1-AAC-Files, die ich nach Flac konvertieren will. Sämtliche meiner Encoder schlagen fehlt, interessanterweise bei ALLEN 6.1-AACs, nicht aber bei 7.1-AACs. Mit dem VLC kann ich die Tonspur in der Matroska-Datei problemlos abspielen. Ich habe in einer virtuellen Maschine mit einem Windows-Gast die Dateien in MeGui versucht und auch über ein AviSynth-Script mit LSmash-Source. Das Ergebnis ist immer kürzer als der tatsächliche Film ist. FFmpeg bringt diesen Fehler:
Code
