Peertube can mirror a YouTube channel automatically, but it will probably be hard to find an instance that allows it, unless it’s your own channel.
Otherwise, you can setup peertube yourself and mirror away ;)
You could use yt-dlp to download the videos / channels / playlists you want to save, although they wouldn't be available online.
I've had no issues with my combo: blocky container (dns), uBlock origin, and LibRedirect (manually configured with nearby instances).
I don't have issues too but Google is expirementing things like server side ads injection that will be hard to circumvent.
If you're into selfhosting (this is datahoarder after all) I recently got around to backing up my fav channels with
https://www.tubearchivist.com/
and it's very good indeed.
One thing this recent ad injection debacle has me worried about is that I’ll open an archived download of a YouTube video and find ads in my files. I have hesitated to continue my personal archival project until I could be 100% sure my downloads are clean, because I can’t go through everything to make sure they didn’t inject a 5 second ad somewhere.
I guess if you get the length with yt-dlp, and then compare with the downloaded file, and the length is within a one second tolerance, it should be fine. At least I would think the length that yt-dlp extracts would not include the baked in ad, but of course youtube could make it so.
Btw I haven't heard about this thing since it first came out. Is it really happening?
Yes it happening but it is in the experiment phase so few users are seeing that.
Who are we?
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
We are one. We are legion. And we're trying really hard not to forget.
