+or
+Parameter:  {“action”:“subtitledelayplus”}
+===== Extract subtitles =====
+Extract subtitle with specific metadata title:
+<code>
+for f in *.mkv; do ffmpeg -hide_banner -i "$f" -c copy -map 0:s:m:title:"English [ForcedNarrative]" "${f%.*}.en.forced.srt"; done
+for f in *.mkv; do ffmpeg -hide_banner -i "$f" -c copy -map 0:s:m:title:"angličtina" "${f%.*}.en.srt"; done
+#extract 2 at once
+for f in *.mkv; do ffmpeg -hide_banner -i "$f" -c copy -map 0:s:m:title:"English [ForcedNarrative]" "${f%.*}.en.forced.srt" -c copy -map 0:s:m:title:"angličtina" "${f%.*}.en.srt"; done
+</code>
+===== Set subtitle to forced =====
+This copies the video and audio stream of an mp4 file, sets the first mov_text subtitle stream to 'forced' and the second to normal:
+<code>
+ffmpeg -i input.mp4 -vcodec copy -acodec copy -map 0:v:0 -map 0:a:0 -map 0:s:0 -c:s mov_text -disposition:s:0 forced -map 0:s:1 -disposition:s:1 0 output.mp4
+</code>
+For mkv files, this probably needs to be srt instead of mov_text.
