У меня есть несколько видео файлов в кодеке H.264 и аудио DTS. Моя цель - преобразовать аудиодорожки (в основном 2 дорожки, английскую и немецкую) в AAC, но также сохранить аудиодорожку DTS.
Я попробовал эту команду, но она только конвертирует треки и заменяет треки DTS на AAC.
$ ffmpeg -i input.mkv -map 0 -c:v copy -c:a libfdk_aac -b:a 128k \

Что я должен сделать, чтобы треки DTS и AAC находились в выходном файле?
