@romin hm actually there's another thing I'd better to do. Can you tell what's your anime watch workflow? except mpv, I'm not sure how to optimize finding & downloading releases and subs
@vertka the neat thing about nyaa is that it allows you to compose your rss feeds per uploader like this https://nyaa.si/?page=rss&u=subsplease&q=frieren+1080p|urusei+1080p
And you can throw those RSS feeds into qbittorrent/rtorrent for example. There are also multiple release groups that ultimately just rip from the official source but might do extra things like clean up the typesetting/fix subs/encode into h265/av1. Some aren't even on nyaa but only on https://animetosho.org/. If you got a box laying around you can throw sonarr at it and then filter through there. Hf.
the rss feed should include different entries for each version, rss managers generally mark already downloaded entries as downloaded, but you can also mark entries as already downloaded manually so you don't download stuff you already downloaded before.
Neither isos nor anime is big on deltas like that so it's generally the entire thing every time. With anime you have the advantage that subs can be seperated so if an episode requires a v2 (a sub with fixes) which some sub groups actually do (or some random does it for them, it depends) they can just throw out a subfile which you just put into your video player or w/e, but it's rare nowadays.
Regardless, RSS feeds are generally not a good tool for deltas anyway because you might just decide to skip a release anyway.
@smug@romin speaking about RSS torrenting, I can't figure out how to automate it. For example I want to have up to date archlinux iso when it get released, replacing old torrent with new. And something similar with anime, so I don't need to redownload everything on each new episode release, just updated parts.
