ffmpeg flac в aac (libdfdk_aac) отсутствуют метаданные

Я хочу конвертировать альбом из flac в aac. После конвертации в aac-файле отсутствуют все метаданные исходного flac-файла. Я уже пробовал конвертировать его с -map_metadata 0аргументом

Моя команда выглядела так:

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

.aacявляется сырым потоком битов AAC и не содержит метаданных. Вывод в .m4aили, может быть, даже .mp4.
