subtitles don't work on Windows S.O

[guiima]

I'm trying to add a subtitle to the video but it doesn't work.

The input.mp4 file is correct and the subtitles in .srt format are also correct, as I add it to the Windows video software and it works.

I am using the following command:

await ffmpeg.run([ '-i', 'input.mp4', '-vf', 'subtitles=legend.srt', 'output.mp4', ]);

result command: run ffmpeg command: -i input.mp4 -vf subtitles=legend.srt output.mp4

Does anybody know how to solve this?
