Я борюсь с этим конкретным примером кодирования mkv в h264. 0:0 — это видео; 0:1 — это аудио (англ.), а 0:9 — это субтитры англ., которые появляются только тогда, когда говорят на японском языке. Я хочу кодировать видео в h264, скопировать аудио и жестко закодировать субтитры в видеодорожку. Проблема в следующем: 0:9, похоже, поврежден:
Could not find codec parameters for stream 9 (Subtitle: hdmv_pgs_subtitle (pgssub)): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' options
Вот что у меня получилось на данный момент:
ffmpeg -i .\sample.mkv -map 0:0 -map 0:1 -map 0:9 -vcodec h264 -c:s mov_text sample.mp4 -analyzeduration 2147483647 -probesize 2147483647
И вот результат:
Error while opening encoder for output stream #0:2 - maybe incorrect parameters
such as bit_rate, rate, width or height
Здесь образецЯ пытаюсь обработать...
(Обратите внимание, что в образце нет субтитров, поскольку это единственный монолог на английском языке)
Интересно, что когда я ввожу весь фильм, ffmpeg жалуется не только на поток 9, но и на все остальные потоки субтитров 3-8. Но на этот раз он фактически выдает мне метаданные для потока 9:

Это может быть связано с тем, что поток 9 технически не содержит ничего, кроме сэмпла.
Может быть, кто-то знает что-то; Спасибо Редактировать: Полные метаданные Пример:

решение1
Команда, которую вы дали, пытается добавить субтитры в MP4 как мягкие субтитры, а не записывать их на жесткий диск, но вам нужно использовать фильтр subtitlesдля преобразования мягких субтитров в жесткие субтитры.
Что-то вроде этого
ffmpeg -i .\sample.mkv -filter_complex "[0:v][0:s]overlay[v]" -map "[v]" -map "0:a" -c:v h264 -c:a copy sample.mp4
должно сработать.
ПРАВКА 1
После публикации примера стало ясно, что исходный звук не является AAC, поэтому нам необходимо перекодировать звук: -c:a copyработать не будет.

Как это работает? Давайте рассмотрим аргументы:
- Сначала открываем файл:
-i sample.mkv - Затем мы объединяем изображение (0:v) с софтсабами (0:s) с помощью фильтра - фильтр - это конструкция, которая не только изменяеткодированиесреды, но и еесодержание. В этом случае мы изменяем изображение, жестко встраивая в него субтитры и создавая именованный поток с именем
v. - Далее мы сообщаем ffmpeg, какие потоки обрабатывать: для изображения он должен использовать
v, для звука он должен использовать аудио исходного файла (0:a). Мы используем-mapдля их установки. - Наконец, нам необходимо закодировать вывод —
-c:vопределяет кодек для видео, а-c:aопределяет его для аудио.
