Я пытаюсь использовать ffmpeg для преобразования и нормализации звука в файле wav на компьютере с Windows 7. Кажется, что я могу сделать любой без проблем, но каждый раз, когда я пытаюсь сделать оба, я получаю эту ошибку от Windows Media Player, пытающегося воспроизвести ее: «Windows Media Player не может воспроизвести файл. Проигрыватель может не поддерживать тип файла или может не поддерживать кодек, который использовался для сжатия файла. "
Теперь, это странно для меня, потому что, если я просто конвертирую файл или просто нормализую его, нет проблем с его воспроизведением. Кроме того, не имеет значения, в каком порядке я выполняю операции или пытаюсь ли я их выполнять в одной строке; результат всегда один и тот же.
Для справки, когда я конвертирую файл, я использую ffmpeg -i infile.wav -c:a aac -b:a 64k outfile.m4a а когда я его нормализую, я использую ffmpeg -i infile -af "loudnorm" outfile .
Кто-нибудь сталкивался с этим или есть идеи для решения?
Обновление с журналом: у меня нет доступа к файлам полного размера, которые я сейчас конвертирую, но ниже приведен журнал для комбинированного вызова тестового файла, сделанного на том же оборудовании.
