I was planning on using either the one by kannagi0303 from github or stacher.
update: I have setup the one from github, seems to do the job. Still can’t figure out downloading subtitles using gui and using the yt-dlp terminal version for that. Link for what I am using: https://github.com/kannagi0303/yt-dlp-gui
The CLI is simple enough that I don’t really bug with any GUI abstractions. I used tubesync for a while on unRAID with pretty decent success, but I eventually ran into some limitations and ended switching to a cron job.
