-l LANGUAGES [LANGUAGES ...]
Subtitle languages to extract (ISO 639-2 codes). If only one language is extracted,
then the output file will have the same name as the video file. Otherwise `_lang`
will be appended to the name.
-
Output will be put in the same folder as the source, only with different extension.
.mp4.
for the video and_{lang}.srt
for the subtitles. -
The video is not recompressed, just copied without quality loss.
-
(not tested) If there is no MP4 video in the MKV file, the video will still be extracted as
.mp4
, but will need a different player.
