Description
When I download subtitles from a channel en masse via (
youtube-dl --skip-download --write-auto-sub --write-sub --sub-lang en --sub-format best <someChannelOrPlaylist>, it ought to have an option to skip doing so for videos that already have their subtitles downloaded.This is a bit tricky when it comes to auto-generated subtitles, as these may change as the algorithm changes, but even these should be skippable if a version has already been downloaded. This is important for my own purposes, as I am using ytdl to automate archiving searchable transcripts (auto-generated) of various channels and when these channels update, it would be nice to be able to skip things I've already downloaded.
