Estoy luchando con este ejemplo específico de codificación de un mkv en h264. 0:0 es vídeo; 0:1 es audio (inglés) y 0:9 son subtítulos en inglés que solo aparecen cuando se habla japonés. Quiero codificar video en h264, copiar audio y codificar los subtítulos en la pista de video. El problema es: 0:9 parece estar dañado:
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
Esto es lo que se me ocurrió hasta ahora:
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
Y este es el resultado:
Error while opening encoder for output stream #0:2 - maybe incorrect parameters
such as bit_rate, rate, width or height
Aquí está el muestraEstoy tratando de procesar...
(Tenga en cuenta que los subtítulos no están presentes en la muestra ya que es el único monólogo en inglés)
Curiosamente, cuando ingreso la película completa, ffmpeg se queja no solo de la transmisión 9, sino también de todas las demás transmisiones de subtítulos 3-8. Pero esta vez me da metadatos para la transmisión 9:
Stream #0:9(eng): Subtitle: hdmv_pgs_subtitle

Lo que podría deberse a que técnicamente la secuencia 9 no contiene nada solo durante la muestra.
Quizás alguien sepa un par de cosas; Gracias Editar: Muestra de metadatos completos:

Respuesta1
El comando que diste intenta agregar los subtítulos como subtítulos suaves al MP4, no grabarlos, pero debes usar el subtitlesfiltro para convertir los subtítulos suaves en subs duros.
Algo parecido a
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
debería funcionar.
EDITAR 1
Después de publicar la muestra, quedó claro que el audio original no es AAC, por lo que necesitamos volver a codificar el audio: -c:a copyno funcionará.
correr
ffmpeg -i .\sample.mkv -filter_complex "[0:v][0:s]overlay[v]" -map "[v]" -map "0:a" -c:v h264 -c:a aac sample.mp4
Funciona como se esperaba.
EDITAR 2
¿Cómo funciona esto? Repasemos los argumentos:
- Primero abrimos el archivo:
-i sample.mkv - Luego combinamos la imagen (0:v) con los softsubs (0:s) usando un filtro; un filtro es una construcción que no solo cambia elcodificacióndel medio, sino también de sucontenido. En este caso, cambiamos la imagen grabando los subtítulos en ella y creando una secuencia con nombre llamada
v. - A continuación le decimos a ffmpeg qué transmisiones procesar: para imagen, debe usar
