Po delsim testovani jsem se dopracoval k mp4box
https://github.com/gpac/gpac/wiki/MP4Box
kde manualu zminuji moznost prejmenovani tkz. "Title" pomoci
To replace the label on an audio or subtitle track (uses udta "name" atom, shown by players like vlc):
MP4Box -udta 3:type=name -udta 3:type=name:str="English" file.mp4
Tak jsem zkousel mp4box pro extrakci videa/audio/titulku a zpetne slouceni,
coz funguje jak ma podle manualu, ale v sekci "title" to nechava tohle:
Title: ddplus-2.0-dash-English.eac3:lang=eng@GPAC2.2-rev0-gab012bbf-master / English
Nevi nekdo jak umazat z toho UDTA atomu "ddplus-2.0-dash-English.eac3:lang=eng@GPAC2.2-rev0-gab012bbf-master /" aby tam zustalo jen "English"?
V Issues sice maji dva tikety:
https://github.com/gpac/gpac/issues/33
https://github.com/gpac/gpac/issues/1606
ale oba dva jsou zavrene ...
