Summary of the bug: ffmpeg subtitle filter is using FriBidi to render text
irrespective of the language and there is no option to change it to
another text shaper like Harfbuzz. But it works if I convert srt to ass
and use the ass filter.
How to reproduce:
{{{
% ffmpeg -i input_video.mp4 -vf subtitles=malayalam.srt output.mp4
}}}
I am trying to burn subtitles from https://malayalamsubtitles.org/ .
Example text from both ffmpeg and vlc : https://i.imgur.com/n2F69Ns.png
Subtitle I tried to burn is attached.
