Re:FFMpeg DVB-C TS - Trim + re-mux do MKV a MP4
« Odpověď #1 kdy: 25. 12. 2023, 18:35:05 »
Nejdu s dobou ... :(

Napadlo mne proverit funkcnost teletext titulku v zarizeni kde jsem to nahraval.
A po zapnuti teletextu a zmeny stranek na 888 se teletextove stranky nacitaji a bezi porad dokola a
titulky se nenactou ......dvb_subtitle funguji jak maji.

Je to chyba na strane DVB-C poskytovatele?
Pouziva nekdo teletext titulky na Vu+ s OpenPLi 8.3?

Proveruji, jestli skryte titulky v teletextu nabizeji, ale tady nic:
https://www.ceskatelevize.cz/vse-o-ct/jak-sledovat/televizni-signal/o-televiznim-vysilani/dodatkove-sluzby/skryte-titulky/

Aha, takze dvb_teletext = "Teletextové skryté podtitulky" uz nejsou podporovany ani u "Pozemni" ani u "Satelitni" distribuce
