Subtitle encoding currently only possible from text to text or bitmap to bitmap

An unknown error occurred with FFmpeg.

Hey!

Thanks for using Plexus, sorry that you've encountered an error.

The subtitle stream for that file is encoded in dvd_subtitle, which essentially stores subtitles as bitmap images rather than genuine text. Unfortunately, MKVs don't support this format, and we can't easily extract the subtitles for external usage either.

Plexus is currently undergoing a complete rewrite in Golang for v2.0, so I'll add this as one of the planned features for release. In the meantime, I would recommend manually converting that file and map out the subtitles:

ffmpeg -y -i "/torrents/_Complete/TV/8.Out.Of.10.Cats.Does.Countdown.S08E01.HDTV.x264-TLA[ettv]/Season 14/8 Out of 10 Cats Does Countdown (2013) - 2018-12-23 21 00 00 - Christmas Special (copy 1).ts" -map 0 -map -0:2 -preset faster -max_muxing_queue_size 1024 -movflags faststart -threads 2 -crf 20 -level 4.1 -c:v libx264 -c:a libfdk_aac -stats "/encoded/8.Out.Of.10.Cats.Does.Countdown.S08E01.HDTV.x264-TLA[ettv]/Season 14/8 Out of 10 Cats Does Countdown (2013) - 2018-12-23 21 00 00 - Christmas Special (copy 1).mkv"
