I'm told it's possible to embed subtitles (.srt) into video files (.avi) using ffmpeg, but I can't find any mention of it in the man page. Is this possible? What command do I use?

From Pier's link, specifically:
ffmpeg -i video.avi -vf subtitles=subtitle.srt out.avi
This creates a hard-sub ("burns" the subtitles into the video images) so you can't hide the subtitles and the change is irreversible!
I've used this successfully with the current static git ffmpeg release.

This filter requires ffmpeg to be compiled with --enable-libass, according documentation.Nakamoto– Nakamoto2021-03-26 02:33:50 +00:00Commented Mar 26, 2021 at 2:33

Thx, resulting subtitles was smaller than i am used to, i would increase 50%. Someone mention:
subtitles=subtitle.srt:force_style='Fontsize=20'ffmpeg.org/ffmpeg-all.html16851556– 168515562022-01-14 16:24:06 +00:00Commented Jan 14, 2022 at 16:24
From man ffmpeg:
Subtitle options:
-scodec codec Force subtitle codec ('copy' to copy stream).
-newsubtitle Add a new subtitle stream to the current output stream.
-slang code Set the ISO 639 language code (3 letters) of the current subtitle stream.
So:
ffmpeg -newsubtitle subtitles.srv -i video.avi ...

If I use instead of

Sufficient is
ffmpeg -newsubtitle subtitles.srt -i video.avi result.avibut this ends with the message above. I hoped that result.avi is output file. I tried it with-o result.avitoo but without success.xralf– xralf2011-10-27 11:22:47 +00:00Commented Oct 27, 2011 at 11:22 -
1I don't know why this didn't work for me (maybe wrong file or problem with ffmpeg). I tried this command instead

@ShawnJ.Goff: This did not work for me either. What version of ffmpeg are you using, and what OS?Faheem Mitha– Faheem Mitha2012-04-07 20:52:51 +00:00Commented Apr 7, 2012 at 20:52
ffmpeg developers are working with subtitle support, but as far as I know it's only working in the latest ffmpeg. mencoder will burn subtitles instantly, if you want to try that instead.
