#10356(undetermined:new): Incorrect escaping text from srt subtitles

#10356: Incorrect escaping text from srt subtitles --------------------------------------+---------------------------------- Reporter: Ashark | Type: defect Status: new | Priority: normal Component: undetermined | Version: 6.0 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | --------------------------------------+---------------------------------- Summary of the bug: I want to literally place "\n" string (not actually a line break) to the video. I created an srt file and hardsubbed it with subtitle video vilter: {{{ $ ffmpeg -hide_banner -loglevel error -y -f lavfi -i color=size=1280x720:rate=10:color=black -vf "subtitles=subtitle_with_n.srt:force_style='Alignment=10,Fontsize=12'" -frames:v 1 output.png ffmpeg version n6.0 Copyright (c) 2000-2023 the FFmpeg developers built with gcc 12.2.1 (GCC) 20230201 }}} But the escaping is done wrong. To hardsub the "\n" string, I escape backslash in srt: "\\n". But instead of escaping the backslash, it escapes the n, and the first '\' is written as is. I created this file subtitle_with_n.srt: {{{ 1 00:00:00,000 --> 10:00:00,000 line 1 \ \ \ backslash ampersand entity (also tried N letter entity) neither work in vlc nor in ffmpeg. line 2 \\n escapes n instead backslash. On vlc it makes backslash and breaks line. On ffmpeg it is backslash and space. line 3 \⁠n used wordjoiner (U+2060), works line 4 \n zero width space, works in vlc, works in ffmpeg. line 5 \n breaks line in vlc, make space in ffmpeg. <b>Bold</b> tag works in both. line 6 \<i></i>n works for vlc, but in ffmpeg it is wrong. }}} This is self commenting. See screenshot for result. The expected non-crutch way is escaping work as normal: going from left to right of the string. Additional info: #9058 - bug about possibility to encode ampersand entities. #9808 - similar bug about escaping in another type of subtitles https://github.com/libass/libass/issues/194#issuecomment-351902555 - workaround by using word joiner symbol. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10356> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#9058(avcodec:new): lavc/htmlsubtitles.c does not parse HTML ampersand escapes

#9058: lavc/htmlsubtitles.c does not parse HTML ampersand escapes -------------------------------------+------------------------------------- Reporter: thebombzen | Type: defect Status: new | Priority: normal Component: avcodec | Version: git- Keywords: | master htmlsubtitles,subrip,srt,srtdec | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- `libavcodec/htmlsubtitles.c` has a parser for `<html>` tags using angled brackets, but it ignores HTML escapes like `<` and `&`. This means there's no way to put an HTML tag in a subtitle format like SubRip, because `<` is passed as is, and `<tags>` are not passed if they are not recognized. For context WebVTT's parser does support `<` (in compliance with spec), but SubRip cannot because there's no way to escape a `<` using the current decoder/parser. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9058> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
