mpv --sid=auto --secondary-sid=auto --sub-pos=95 --slang de,en movie.mkv
Same works for youtube URLs. If it doesn't work, changing "de,en" to "en,de" may help. mpv --sid=auto --secondary-sid=auto --sub-pos=95 --slang de,en movie.mkv
Same works for youtube URLs. If it doesn't work, changing "de,en" to "en,de" may help.With a computer running mpv and plugged into the TV everything just works and I can trivially fix common issues like subtitle/audio sync with my phone as the remote.
On-topic: mpv seems to have a similar language learning extension to OP https://github.com/oltodosel/interSubs
Having a scriptable media player is really something else.
