A tady se to zastavilo u streamu "0:6 dvb_subtitle".
Takze ted hledam "ffmpeg dvb_subtitle"
https://trac.ffmpeg.org/wiki/ExtractSubtitlesVerze ffmpeg podporuje u "dvb_subtitle" i decoder, i encoder = dvbsub.

Codecs:
D..... = Decoding supported

..V... = Video codec
..A... = Audio codec
..S... = Subtitle codec
..D... = Data codec
..T... = Attachment codec
...I.. = Intra frame-only codec
....L. = Lossy compression
.....S = Lossless compression
Ale pokud z toho budu vytahovat ty titulky, tak je asi treba nahravku trimovat, jinak
asi nebudou sedet timestamps pozdeji .....
Takze jsem to takhle ostrihl (u CT nastesti nemaji v prubehu filmu reklamy):

v MPV i VLC? (Ve VLC zkousim 888, ale nic a je to nejnovejsi verze 3.0.20).
https://mpv.io/manual/master/--teletext-page=<1-999>
This works for dvb_teletext subtitle streams, and if FFmpeg has been compiled with support for it.
mpv --teletext-page=888 --sid=1 CT1.HD.-.Tri.orisky.pro.Popelku.ts
Zapinam s "V" a prepinam na prvni stopu titulku, ale nic
