Curious in general how often Youtube breaks things on their end, i.e. how long roughly this specific version of youtube-dl is expected to keep working without any active development?
I use youtube-dl fairly infrequently... maybe once a month or so. Nearly every time I used it it would not download the video I wanted - so I'd do a "youtube-dl -u", then it would work.
Just spreading the repo around isn't going to help for very long.
