| * | sub: make filter_sdh a "proper" filter, allow runtime changes | wm4 | 2020-02-16 | 1 | -9/+52 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, filter_sdh was simply a function that was called by sd_ass directly (if enabled). I want to add another filter, so it's time to turn this into a somewhat more general subtitle filtering infrastructure. I pondered whether to reuse the audio/video filtering stuff - but better not. Also, since subtitles are horrible and tend to refuse proper abstraction, it's still messed into sd_ass, instead of working on the dec_sub.c level. Actually mpv used to have subtitle "filters" and even made subtitle converters part of it, but it was fairly horrible, so don't do that again. In addition, make runtime changes possible. Since this was supposed to be a quick hack, I just decided to put all subtitle filter options into a separate option group (=> simpler change notification), to manually push the change through the playloop (like it was sort of before for OSD options), and to recreate the sub filter chain completely in every change. Should be good enough. One strangeness is that due to prefetching and such, most subtitle packets (or those some time ahead) are actually done filtering when we change, so the user still needs to manually seek to actually refresh everything. And since subtitle data is usually cached in ASS_Track (for other terrible but user-friendly reasons), we also must clear the subtitle data, but of course only on seek, since otherwise all subtitles would just disappear. What a fucking mess, but such is life. We could trigger a "refresh seek" to make this more automatic, but I don't feel like it currently. This is slightly inefficient (lots of allocations and copying), but I decided that it doesn't matter. Could matter slightly for crazy ASS subtitles that render with thousands of events. Not very well tested. Still seems to work, but I didn't have many test cases. | ||||
| * | sub: enhance SDH filtering | Dan Oscarsson | 2020-02-09 | 1 | -0/+8 |
| | | | | | | It is not uncommon with a speaker label with [xxxx] inside. They should also be filtered out. | ||||
| * | sub: recognize UTF-8 characters in SDH subtitle filter | zc62 | 2019-03-02 | 1 | -1/+4 |
| | | | | | | | | | | | | Only printable ASCII characters were considered to be valid texts. Make it possible that UTF-8 contents are also considered valid. This does not make the SDH subtitle filter support non-English languages. This just prevents the filter from blindly marking lines that have only UTF-8 characters as empty. Fixes #6502 | ||||
| * | filter_sdh: remove pointless set_pos function | wm4 | 2017-04-20 | 1 | -17/+10 |
| | | | | | | This change was requested during patch review, but apparently it was overlooked on merge. | ||||

| * | sub: minor sdh filter fixes | Dan Oscarsson | 2017-04-15 | 1 | -1/+2 |
| | | | | | | | | | | | When doing harder filtering not require a space after : results in lines with a clock (like 10:05) to be taken as a speaker label. So require a space after : even when doing harder filtering as missing space is very uncommon. Some like to add text in parentheses in the speaker label, like XXX (loud): or just (loud): allow parentheses when doing harder filtering | ||||
| * | sub: add SDH subtitle filter | Dan Oscarsson | 2017-03-25 | 1 | -0/+459 |
| Add subtitle filter to remove additions for deaf or hard-of-hearing (SDH). This is for English, but may in part work for others too. This is an ASS filter and the intention is that it can always be enabled as it by default do not remove parts that may be normal text. Harder filtering can be enabled with an additional option.
