I'm struggling to find a one line command to merge new subtitle and delete existing ones from video file.
test1.mkv (already contain softcoded subs, dont need them)
test1.srt (only subtitle that i want on video)
Working under ubuntu server 18.04 LTS 64bit
mkvmerge -o output.mkv -S 1.mkv --language 0:hrv --sub-charset 0:utf-8 1.srt
This will do the work
