When reading a dvd/iso/VIDEO_TS, is there any chance metadata could be added to the subtitle streams the same way it is for audio streams?
In particular the language tags, but it would also be very helpful to see the subtitle "content/language extension" information, ie "Forced Caption", "Closed Caption", etc. I'm not sure what all is possible for this field, but the "Forced Caption" would be the most helpful for me.
This site has quite a bit of info about DVD structures and this page in particular about attributes. #19 appears to be the one related to the subtitle content/language extension field.
FYI. One thing I've learned from looking at some other code is the correct field in libdvdread is "code_extension" and NOT "lang_extension". There may be cases where "lang_extension" contains something, but all the DVDs I've checked show "lang_extension" is blank.
