subtitle filter can't render indic languages

Reported by: unni Owned by:
Priority: important Component: avfilter
Version: git-master Keywords: subtitles regression
Cc: Blocked By:
Blocking: Reproduced by developer: yes
Analyzed by developer: no

Description

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.

Your ass library is missing harfbuzz, this cannot be fixed in FFmpeg.

That is not the case. I've compiled libass with harfbuzz and if I use ass filter, it is working fine. But subtitle filter is not using harfbuzz.

Not working:

ffmpeg -ss 00:03:00 -to 00:04:00 -copyts -i input.mp4 -vf subtitles=subtitile.srt:force_style='FontName=RaghuMalayalamSans-Regular' -ss 00:03:00 -y test.mp4

The subtitle filter does not „use“ harfbuzz, libass does.

Then can you tell me why ffmpeg ass filter renders with same libass while the ffmpeg subtitle filter can't?

comment:5 by Carl Eugen Hoyos, 16 months ago

If you really believe that there is an issue that can be fixed in FFmpeg please test current FFmpeg git head and (after making your terminal window a little wider) provide the command line you tested together with the complete, uncut console output to make this a valid ticket.

comment:6 by unni, 16 months ago

I've compiled by following https://trac.ffmpeg.org/wiki/CompilationGuide/Centos which uses the snapshot. I'll try the git.

But as per https://ffmpeg.org/ffmpeg-filters.html#ass only ass has option to select the shaping engine. There is no such option for subtitle filter. I guess then it's ffmpeg which selects the shaping engine.

comment:7 by Carl Eugen Hoyos, 16 months ago

The snapshot is current FFmpeg git head which you did not use above.

comment:8 by unni, 16 months ago

Yes, that output is from Mac which is installed through homwbrew. I am using the snapshot in my CentOS server. Results are same. I'll post the command output from that.
