J'ai un MKV que j'utilise pour créer un DVD avec DeVeDe.
Le MKV contient des sous-titres intégrés au format vobsub, que DeVeDe ne prend pas en charge (ou est bogué, je ne suis pas sûr).
J'ai décidé de graver les sous-titres sur la sortie en utilisant l'option de paramètres supplémentaires de ffmpeg, que j'ai pris ici :
https://trac.ffmpeg.org/wiki/How%20to%20burn%20subtitles%20into%20the%20video
J'ai donc mis à jour la dernière version de ffmpeg et ajouté les paramètres supplémentaires suivants :
-filter_complex "[0:v][0:s]overlay[v]" -map [v] -map 0:a
Donc la commande complète est :
ffmpeg -i ~/Input.mkv -vf scale=720:412,fifo,pad=720:576:0:82:0x000000 -y -target pal-dvd -sn -acodec copy -g 12 -t 60.0 -ac 2 -s 720x576 -threads 3 -trellis 1 -mbd 2 -b 2616000 -aspect 16:9 /var/tmp/previewfile_01_01.mpg -filter_complex "[0:v][0:s]overlay[v]" -map [v] -map 0:a
Mais de DeVeDe j'obtiens :
[AVFilterGraph @ 0xa744ca0] No such filter: '"'
En l'exécutant dans un Shell, on obtient :
Output pad "default" with type video of the filter instance "Parsed_overlay_0" of overlay not connected to any destination
La documentation du filtre est ici : http://ffmpeg.org/ffmpeg-filters.html#overlay-1
Mais je ne peux pas faire la tête ou la queue de ça. Les paramètres -map sont également un mystère.
Voici les détails des flux :
