WebVTT spec specifies a dozen HTML escapes that should be handled,
including '>', '<' and '&'. These aren't converted back to the
proper characters.
FFmpeg version:
{{{
% ffmpeg -i htmlescapes.vtt out.srt
ffmpeg version N-75818-g8135b1e Copyright (c) 2000-2015 the FFmpeg
developers
built with gcc 5.2.0 (Rev4, Built by MSYS2 project)
}}}
Attached is an example vtt file, result with this build and proper result.
Examples of where these html escapes are used can be found by getting the
subtitles from any video in Comedy Central's site using something like
youtube-dl. Example:
{{{
% youtube-dl --all-subs "http://www.cc.com/video-clips/52dpzm/the-daily-
show-with-trevor-noah-terrible--unending-national-tragedies"
}}}
