command linevideo-subtitles
I want to use the command line to extract subtitles from video files.
I want to extract subtitles from a lot of files. That is why I want a CLI tool.
Ideally it should work with any video format that supports embedded subtitles.
For example:
subextract -f RevolutionOS.mp4
Extracting English.srt
Extracting French.srt
Extracting Russina.srt
All subtitles extracted

MPV has no menus for DVD, but it works very well. To start the DVD, access the DVD folders and drag&drop the VIDEO_TS folder onto the MPV's window. Then do the same with the subtitle file.
From my experience, in this case the main movie is started directly.
To do that with a command, use something like
mpv dvd://
or
mpv /media/username/*/VIDEO_TS
To get the correct path for that, mount the DVD, copy/paste the VIDEO_TS path and replace the variable DVD movie name with *, as indicated under this question.
That command can be used in a panel launcher, .desktop file or shortcut to start playing the DVD with one click.
An example of .desktop launcher:

Replace username with yours and the icon path. You can use this icon :)
or this
When the player is started with the command mpv /dev/sr0, it will play and seek through all included streams including menus as if in a single file (no DVD menu support).
SMPlayer
Does the job of adding external subtitles to DVDs. No DVD menus by default, although this can be enabled as an experimental feature under Options -Preferences - Drives. (DVD menus seem to work if mplayer is selected as multimedia engine but not with the more recent mpv.) When the menus are not enabled the main movie is shown in playlist as one separate entry and is easy to identify and add a subtitle to it.
So, start playing the item that corresponds to the movie and then add the external subtitle: it should work very well.
External dvd subtitles usually look better than the ones on the dvd.

There are such tools, specific to each container type (assuming subtitles are stored as text, not mixed in the video stream):
mkvtoolnixMP4Boxffmpeg/avconvFor your question specifically, the command line would be
Where possible values of
trackIDcan be deduced from the output ofFor subtitles which are mixed into the video stream (so-called hardsubs), OCR software is required. There seem to be ready-made solutions here, for example subtitleripper + GOCR for VobSub (common format for DVD), but I have no experience with those and no idea how good they are.
